Endometrial cancer is the most common gynaecological cancer in high income countries and its incidence is rising globally. Although an ageing population and fewer benign hysterectomies have contributed to this trend, the growing prevalence of obesity is the major underlying cause. Obesity poses challenges for diagnosis and treatment and more research is needed to offer primary prevention to high-risk women and to optimise endometrial cancer survivorship. Early presentation with postmenopausal bleeding ensures most endometrial cancers are cured by hysterectomy but those with advanced disease have a poor prognosis. Minimally invasive surgical staging and sentinel-lymph-node biopsy provides a low morbidity alternative to historical surgical management without compromising oncological outcomes. Adjuvant radiotherapy reduces loco-regional recurrence in intermediate-risk and high-risk cases. Advances in our understanding of the molecular biology of endometrial cancer have paved the way for targeted chemotherapeutic strategies, and clinical trials will establish their benefit in adjuvant, advanced, and recurrent disease settings in the coming years.Copyright © 2022 Elsevier Ltd.

To assess the prognostic performance of the 2023 International Federation of Gynecology and Obstetrics (FIGO) endometrial cancer staging schema.This retrospective cohort study queried the Commission-on-Cancer's National Cancer Database. Study population was 129,146 patients with stage I-IV endometrial cancer per the 2009 FIGO staging schema. Stage-shifting and overall survival (OS) were assessed according to the 2023 FIGO staging schema.Upstage (IA → II, 21.4 %; IB → II, 53.0 %) and downstage (IIIA→IA3, 22.2 %) occurred in both early and advanced diseases. Inter-stage prognostic performance improved in the 2023 schema with widened 5-year OS rate difference between the earliest and highest stages (68.2 % to 76.9 %). Stage IA1-IIB and IIC had distinct 5-year OS rate differences (85.8-96.1 % vs 75.4 %). The 5-year OS rate of the 2009 stage IIIA disease was 63.9 %; this was greater segregated in the 2023 schema: 88.0 %, 62.4 %, and 55.7 % for IIIA→IA3, IIIA1, and IIIA2, respectively (inter-substage rate-difference, 32.3 %). This 5-year OS rate of stage IA3 disease was comparable to the 2023 stage IB-IIB diseases (88.0 % vs 85.8-89.5 %). In the 2023 stage IIIC schema (micrometastasis rates: 29.6 % in IIIC1 and 15.6 % in IIIC2), micrometastasis and macrometastasis had the distinct 3-year OS rates in both pelvic (IIIC1-i vs IIIC1-ii, 84.9 % vs 71.1 %; rate-difference 13.8 %) and para-aortic (IIIC2-i vs IIIC2-ii, 82.9 % vs 65.2 %; rate-difference 17.7 %) nodal metastasis cases. The 5-year OS rate of the 2009 stage IVB disease was 23.4 %; this was segregated to 25.4 % for stage IVB and 19.2 % for stage IVC in the 2023 staging schema (rate-difference, 6.2 %).The 2023 FIGO endometrial cancer staging schema is a major revision from the 2009 FIGO schema. Almost doubled enriched sub-stages based on detailed anatomical metastatic site and incorporation of histological information enable more robust prognostication.Copyright © 2024 Elsevier Inc.

Adaptation of existing guidelines can be an efficient way to develop contextualized recommendations. Transparent reporting of the adaptation approach can support the transparency and usability of the adapted guidelines.To develop an extension of the RIGHT (Reporting Items for practice Guidelines in HealThcare) statement for the reporting of adapted guidelines (including recommendations that have been adopted, adapted, or developed de novo), the RIGHT-Ad@pt checklist.A multistep process was followed to develop the checklist: establishing a working group, generating an initial checklist, optimizing the checklist (through an initial assessment of adapted guidelines, semistructured interviews, a Delphi consensus survey, an external review, and a final assessment of adapted guidelines), and approval of the final checklist by the working group.International collaboration.A total of 119 professionals participated in the development process.Participants' consensus on items in the checklist.The RIGHT-Ad@pt checklist contains 34 items grouped in 7 sections: basic information (7 items); scope (6 items); rigor of development (10 items); recommendations (4 items); external review and quality assurance (2 items); funding, declaration, and management of interest (2 items); and other information (3 items). A user guide with explanations and real-world examples for each item was developed to provide a better user experience.The RIGHT-Ad@pt checklist requires further validation in real-life use.The RIGHT-Ad@pt checklist has been developed to improve the reporting of adapted guidelines, focusing on the standardization, rigor, and transparency of the process and the clarity and explicitness of adapted recommendations.None.

AMSTAR 2 was originally developed for systematic reviews (SRs) of healthcare interventions. The aim of this study was to assess the applicability of AMSTAR 2 to systematic reviews (SRs) of non-intervention studies STUDY DESIGN AND SETTING: This was a meta-research study. We used 20 SRs for each of the following four types of SRs: Diagnostic Test Accuracy reviews, Etiology and/or Risk reviews, Prevalence and/or Incidence reviews, and Prognostic reviews (80 in total). Three authors applied AMSTAR 2 independently to each included SRs. Then, the authors assessed the applicability of each item to that SR type and any SR type.Researchers unanimously indicated that 7 of 16 AMSTAR 2 items were applicable for all four specific SR types and any SR type (items 2, 5, 6, 7, 10, 14 and 16), but 8 of 16 items for any SR type. These items could cover generic SR methods that do not depend on a specific SR type.AMSTAR 2 is only partially applicable for non-intervention SRs. There is a need to adapt/extend AMSTAR 2 for SRs of non-intervention studies. Our study can help to further define generic methodological aspects shared across SR types and methodological expectations for non-intervention SRs.Copyright © 2023 Elsevier Inc.

This article is the first of a series providing guidance for use of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system of rating quality of evidence and grading strength of recommendations in systematic reviews, health technology assessments (HTAs), and clinical practice guidelines addressing alternative management options. The GRADE process begins with asking an explicit question, including specification of all important outcomes. After the evidence is collected and summarized, GRADE provides explicit criteria for rating the quality of evidence that include study design, risk of bias, imprecision, inconsistency, indirectness, and magnitude of effect. Recommendations are characterized as strong or weak (alternative terms conditional or discretionary) according to the quality of the supporting evidence and the balance between desirable and undesirable consequences of the alternative management options. GRADE suggests summarizing evidence in succinct, transparent, and informative summary of findings tables that show the quality of evidence and the magnitude of relative and absolute effects for each important outcome and/or as evidence profiles that provide, in addition, detailed information about the reason for the quality of evidence rating. Subsequent articles in this series will address GRADE's approach to formulating questions, assessing quality of evidence, and developing recommendations.Copyright © 2011 Elsevier Inc.

To evaluate a new device for obtaining endometrial biopsies which combines global endometrial disruption using a brush with a built-in suction process.Endometrial biopsies were collected, using the GDP-Tao device, from fresh uteri hysterectomy specimens after completion of surgery. Results were compared to final hysterectomy pathology. Specificity and sensitivity and positive and negative predictive values were calculated.Based on a sample size calculation, 42 patients were included in this study. Endometrial tissue adequate for diagnosis was obtained in 93% (39/42) of biopsies. Classifying atypia as a positive result, the sensitivity of the new device was 96% (23/24), with specificity of 87% (13/15). The positive predictive value was 92% (23/25) and the negative predictive value, 93% (13/14). There were 2 nondiagnostic (ND) samples from GDP-Tao with final pathology of benign endometrium. One specimen was ND on both GDP-Tao and final pathology due to absence of tissue after prior endometrial ablation. When stratified by uterine size, benign or malignant, the results were similar.Our validation study showed encouraging results for the GDP-Tao, which combines tissue disruption and aspiration into a single process. The device provides a reliable means of obtaining adequate samples to accurately detect endometrial cancer with a high negative and positive predictive value.

Cytopathology detecting for endometrial cancer is becoming accepted, and Tao Brush is the most widely used sampler for endometrial cells. This study aims to compare the effectiveness between Li brushes and Tao brushes for the diagnosis of endometrial lesions and to evaluate the diagnostic accuracy of endometrial cytology compared with histology.There were 109 patients needing dilation and curettage (D&C) and 21 patients needing hysterectomies included from November 2017 to April 2018. Every patient was sampled by Tao brush and Li brush before D&C or hysterectomy performed. The cytological results were compared based on the gold standard histological results of D&C or hysterectomy.The sensitivity of Li brush cytology for detecting endometrial cancer and atypical hyperplasia was estimated at 83.33%, specificity at 100%, positive predictive value (PPV) at 100%, and negative predictive value (NPV) at 98.02%, respectively. While for the Tao brush, it was 91.67% of sensitivity, 96.04% of specificity, 73.33% of PPV, and 98.98% of NPV, respectively. The kappa value was 0.767, which indicated a substantial agreement. Cytology by both two brushes had a lower insufficient sample rate (2.75% of Tao brush, 4.59% of Li brush) than did D&C (11.93%).Endometrial cytology is a reliable approach for evaluating endometrium with a lower insufficient sample rate. Cytology sampled by both Li brushes and Tao brushes has a high accuracy with histological diagnosis in detecting endometrial cancer and atypical hyperplasia. Combining social and economic benefits, the Li brush may be a better endometrial cell collector.© 2020 Lv et al.

Recently, the research on early detection of precancerous change and endometrial carcinoma has been focusing on minimally invasive procedures for screening. On this basis, we aim to verify the feasibility of endometrial samplers for screening endometrial cancer using Li Brush. We recruited patients undergoing hysterectomy for different diseases from the Inpatient Department of the Department of Obstetrics and Gynecology. Before surgery, endometrial cells were collected by Li Brush. The cytopathologic diagnosis from Li Brush and the histopathologic diagnosis from hysterectomy in the same patient were compared to calculate sensitivity (Se), specificity (Sp), false-negative rate (FNR), false-positive rate (FPR), positive predictive value (PV+) %, and negative predictive value (PV-). The research enrolled 293 women into this self-controlled trial. According to the hypothesis test of paired four lattices, we obtained the following indicators: Se 92.73, Sp 98.15, FNR 7.27, FPR 1.85, PV+92.73, and PV-98.15%. The endometrial sampler Li Brush is an efficacious instrument for screening endometrial cancer.

To evaluate a new technique for processing endometrial cytology for the diagnosis and exclusion of endometrial cancer.All women at risk for endometrial cancer with clinical indications for endometrial biopsy were evaluated by endometrial brush biopsy (Tao Brush, Cook OB-GYN, Bloomington, Indiana) and Pipelle (Cooper Surgical, Shelton, Connecticut) endometrial biopsies during one office visit. Patients were followed longitudinally for the development of endometrial cancer or until undergoing dilatation and curettage or hysterectomy. All comparisons were analyzed using the chi 2 or t test.One hundred one women (mean age, 58; range, 35-86) had endometrial biopsies performed. Median follow-up was > 21 months (range, 3-29). Twenty-two had cancer or atypia, while the remaining had benign diagnoses. When correlated with the final diagnosis, the Tao Brush had 95.5% sensitivity and the Pipelle, 86% sensitivity. Both devices had 100% specificity, positive predictive value of 100% and negative predictive value of 98%. When the results of the two biopsy devices are considered together, the positive and negative predictive value for detecting or excluding endometrial cancer was 100%. Based on 1998 Medicare reimbursements, a simultaneous second office biopsy using the Tao brush could save approximately $67 per case as compared to a sonohistogram and much more when compared to dilatation and curettage.Endometrial cancer can be reliably detected and excluded using these two distinct office biopsy devices simultaneously during one office visit. In patients with an indication for endometrial biopsy, no further diagnostic test may be necessary to exclude or diagnose endometrial cancer or atypia.

To compare the diagnostic accuracy of aspiration biopsy and dilatation and curettage (D&C) in patients diagnosed with endometrial hyperplasia prior to hysterectomy.We retrospectively reviewed medical records of 250 patients diagnosed with endometrial hyperplasia by endometrial sampling between July 2003 and March 2020. Endometrial sampling was performed by aspiration biopsy (n = 150) or D&C (n = 100), followed by hysterectomy within 6 months. Pathological findings of hysterectomy specimens of the two groups were compared to preoperative findings.The overall diagnostic concordance between endometrial sampling specimen including D&C and aspiration biopsy, and hysterectomy specimen was 51.0% (51/100) and 41.3% (62/150), respectively. Patients whose preoperative specimen was obtained by D&C were upgraded less significantly than those who underwent aspiration biopsy (21.0% vs 36.7%; P = 0.008). In particular, significantly fewer patients were upgraded after D&C than after aspiration biopsy in hyperplasia without atypia (12.5% vs 29.0%; P = 0.028). In addition, when the final pathological upgrade rate to endometrial carcinoma was evaluated between the two methods of endometrial sampling, significantly fewer cases were noted after D&C than after aspiration biopsy (15.0% vs 27.3%; P = 0.022).In our study, D&C more accurately reflected the final diagnosis in patients with endometrial hyperplasia than aspiration biopsy based on the histological examination of hysterectomy specimens. When considering the management strategy for women with an endometrial hyperplasia diagnosis obtained by aspiration biopsy, physicians should consider the significant rate of upgraded diseases with this method of endometrial sampling.

To determine the diagnostic accuracy of different endometrial sampling tests for detecting endometrial carcinoma.

To estimate the effect of preoperative diagnostic hysteroscopy on peritoneal cytology in patients with endometrial cancer.A total of 256 charts were reviewed. Two cohorts were established based on diagnosis by hysteroscopy or blind endometrial sampling via either endometrial biopsy or dilatation and curettage (D&C). Malignant or suspicious peritoneal cytology was the primary outcome. Cohorts were compared using logistic regression to correct for potential confounders of stage and grade.A total of 204 cases were diagnosed by endometrial biopsy or D&C, whereas 52 were identified by hysteroscopy. In the endometrial biopsy or D&C arm, 14 of 204 (6.9%) patients had malignant or suspicious cytology compared with 7 of 52 (13.5%) patients in the hysteroscopy arm (P =.15). After logistic regression controlling for stage and grade, the odds ratio for positive cytology after hysteroscopy was 3.88 (95% confidence interval 1.11,13.6; P =.03). Four of the 52 (7.7%) cases diagnosed by hysteroscopy were stage IIIA due to cytology alone compared with 3 of the 204 (1.4%) cases diagnosed by endometrial biopsy or D&C (P =.03).Hysteroscopy appears to be associated with an increased rate of malignant cytology after controlling for confounders of stage and grade. Further, there appears to be an association between hysteroscopy and upstaging patients due to cytology alone.II-2.

The penetration of distention medium into the peritoneal cavity as well as directly into the bloodstream via injured endometrial vessels occurs in a great proportion of patients at hysteroscopy (HSC). This may cause potential risk of dissemination of the malignant cells of endometrial cancer patients. To evaluate the real risk of a poorer prognosis of these patients a prospective multicentric study was started in 1998.Two groups of patients with endometrial carcinoma have been compared. The diagnosis was made in the study group by HSC and targeted biopsy, while in the control group by classical D&C. At the end of the HSC procedure puncture of the cul de sac was performed and the fluid obtained was cytologically examined. In both groups peritoneal lavage was performed at the beginning of the subsequent operation and the collected fluid was again cytologically examined. In the first phase of the study the cytology findings in both groups were compared. In the second phase which is planned for the next five years. the results of follow-up of both groups of patients will be evaluated.The results were evaluated in 134 patients with HSC and in 61 patients with D&C. In the study group a positive finding of malignant cells from the cul de sac was found in four patients (5.3%), a suspect finding in eight patients (10.7%), and a negative finding in 63 patients (84%). In the remaining 59 patients with HSC no peritoneal fluid was obtained. In the fluid from lavage at the beginning of the operation in the same group of HSC patients, a positive finding of malignant cells was found in 12.1%, a suspect finding in 18.2%, and a negative finding in 69.7%. In the control group (after D&C) the fluid from lavage contained malignant cells in eight patients (13.6%), suspect cells in 12 patients (20.3%), and no malignant cells in 39 patients (66.1%). Both groups were comparable for clinical stages of disease.Our results suggest that HSC does not increase the risk of penetration of tumour cells into the peritoneal cavity more than estimates in D&C.

To determine whether hysteroscopy (HSC) increases the risk of intraperitoneal dissemination in endometrial cancer patients.

This single-institution, retrospective study aimed to compare the surgical outcomes of single-port, multi-port, and robot-assisted laparoscopy, as well as laparotomy, in patients with endometrial cancer who underwent surgical staging between January 2006 and December 2017. This study evaluated various parameters, including disease-free survival (DFS), overall survival (OS), recurrence rate (RR), recurrence site, and intra- and postoperative complications. Propensity score matching was performed to account for baseline characteristics, and a total of 881 patients were included in the analysis. The 3-year DFS of single-port laparoscopy was similar to that of the other groups, but laparotomy exhibited a lower 3-year DFS compared to multi-port (p = 0.001) and robot-assisted (p = 0.031) laparoscopy. Single-port laparoscopy resulted in a significantly higher 3-year OS than laparotomy (p = 0.013). After propensity score matching, the four groups demonstrated similar survival outcomes (3-year DFS: p = 0.533; 3-year OS: p = 0.328) and recurrence rates (10.3%, 12.1%, 10.3%, and 15.9% in the single-port, multi-port, and robot-assisted laparoscopy and laparotomy groups, respectively, p = 0.552). Recurrence most commonly occurred in distant organs. The single-port laparoscopy group had the longest operative time (205.1 ± 76.9 min) but the least blood loss (69.5 ± 90.8 mL) and the shortest postoperative hospital stay (5.2 ± 2.3 days). In contrast, the laparotomy group had the shortest operative time (163.4 ± 51.0 min) but the highest blood loss (368.3 ± 326.4 mL) and the longest postoperative hospital stay (10.3 ± 4.6 days). The transfusion rate was 0% in the single-port laparoscopy group and 3.7% in the laparotomy group. Notably, the laparotomy group had the highest wound complication rate (p = 0.001), whereas no wound hernias were observed in the three minimally invasive approaches. In conclusion, the survival outcomes were comparable between the methods, with the benefit of lower blood loss and shorter hospital stay observed in the single-port laparoscopy group. This study suggests that single-port laparoscopy is a feasible approach for endometrial cancer surgical staging.

To compare disease-free survival between minimally invasive surgery and open surgery in patients with high-risk endometrial cancer.We conducted a multicentric, propensity-matched study of patients with high-risk endometrial cancer who underwent hysterectomy, bilateral salpingo-oophorectomy, and staging between January 1999 and June 2016 at two centers. High-risk endometrial cancer included grade 3 endometrioid, serous, clear cell, undifferentiated carcinoma or carcinosarcoma with any myometrial invasion. Patients were categorized a priori into two groups based on surgical approach, propensity scores were calculated based on potential confounders and groups were matched 1:1 using nearest neighbor technique. Cox hazard regression analysis and Kaplan-Meier curves evaluated the association of surgical technique with survival.Of 626 eligible patients, 263 (42%) underwent minimally invasive surgery and 363 (58%) underwent open surgery. In the matched cohort, there were no differences in disease-free survival rates at 5 years between open (53.4% [95% CI 45.6-60.5%]) and minimally invasive surgery (54.6% [95% CI 46.6-61.8]; P=.82). Minimally invasive surgery was not associated with worse disease-free survival (hazard ratio [HR] 0.85, 95% CI 0.63-1.16; P=.30), overall survival (HR 1.04, 95% CI 0.73-1.48, P=.81), or recurrence rate (HR 0.99; 95% CI 0.69-1.44; P=.99) compared with open surgery. Use of uterine manipulator was not associated with worse disease-free survival (HR 1.01, 95% CI 0.65-1.58, P=.96), overall survival (HR 1.18, 95% CI 0.71-1.96, P=.53), or recurrence rate (HR 1.12, 95% CI 0.67-1.87; P=.66).There was no difference in oncologic outcomes comparing minimally invasive and open surgery among patients with high-risk endometrial cancer.Copyright © 2021 by the American College of Obstetricians and Gynecologists.

Despite the potential benefits of minimally invasive hysterectomy for uterine cancer, population-level data describing the procedure's safety in unselected patients are lacking. We examined the use of minimally invasive surgery and the association between the route of the procedure and long-term survival.We used the SEER-Medicare database to identify women with stage I-III uterine cancer who underwent hysterectomy from 2006 to 2011. Patients who underwent abdominal hysterectomy were compared with those who had minimally invasive hysterectomy (laparoscopic and robot-assisted). Perioperative morbidity, use of adjuvant therapy, and long-term survival were examined after propensity score balancing.We identified 6,304 patients, including 4,139 (65.7%) who underwent abdominal hysterectomy and 2,165 (34.3%) who underwent minimally invasive hysterectomy; performance of minimally invasive hysterectomy increased from 9.3% in 2006 to 61.7% in 2011. Robot-assisted procedures accounted for 62.3% of the minimally invasive operations. Compared with women who underwent abdominal hysterectomy, minimally invasive hysterectomy was associated with a lower overall complication rate (22.7% v 39.7%; P <.001), and lower perioperative mortality (0.6% v 1.1%), but these women were more likely to receive adjuvant pelvic radiotherapy (34.3% v 31.3%) and brachytherapy (33.6% v 31.0%; P <.05). The complication rate was higher after robot-assisted hysterectomy compared with laparoscopic hysterectomy (23.7% v 19.5%; P =.03). There was no association between the use of minimally invasive hysterectomy and either overall (HR, 0.89; 95% CI, 0.75 to 1.04) or cancer-specific (HR, 0.83; 95% CI, 0.59 to 1.16) mortality.Minimally invasive hysterectomy does not appear to compromise long-term survival for women with endometrial cancer.© 2016 by American Society of Clinical Oncology.

We sought to analyze the clinicopathologic features, recurrence patterns and survival outcomes of women with high-grade uterine cancer (UC) enrolled on The Gynecologic Oncology Group (GOG) LAP2 trial.This is a post-hoc analysis of LAP-2 patients with grade 3 endometrioid adenocarcinoma (ENDO), uterine serous (USC), clear cell (CC) and carcinosarcoma (CS). Demographics, clinicopathologic features, and recurrence patterns, were compared by histology and surgical approach. Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method.Of the 2600 patients enrolled in LAP-2, 753 patients had high-grade UC: 350 had ENDO, 289 had USC, 42 had CC and 72 had CS. Compared with the ENDO cohort, those with other high-grade subtypes were older (p<0.001) and were more likely to have positive peritoneal cytology (p<0.001), positive lymph nodes (p=0.05) and higher disease stage on final pathology (p<0.001). With a median follow-up time of 60months, compared to patients with ENDO, those with USC, CCC and CS subtypes had higher recurrence rates (p<0.001), extra-pelvic recurrences (p<0.001) and poorer PFS (p<0.001) and OS (p<0.001). Those diagnosed with USC and CS experienced the worst survival outcomes (p=0.003). Patterns of recurrence and survival were not different in those staged with LSC vs LAP. On multivariable analysis, age, stage, pelvic washings and Type II histology were independently and adversely associated with survival.Women with apparent early-stage, USC and CS histologies have poorer outcomes than women with grade 3 endometrioid adenocarcinoma. Patterns of recurrence and survival were not impacted by surgical approach.Copyright © 2016 Elsevier Inc. All rights reserved.

Natural-orifice transluminal endoscopic surgery (NOTES) is performed increasingly often despite the lack of high-quality evidence confirming its safety, especially for malignant diseases. The aim of this prospective study is to verify that vaginal NOTES (vNOTES) can be performed safely and effectively in early endometrial cancer staging surgery.This prospective study was conducted in two tertiary hospitals in southern China from January 2021 to May 2022. A total of 120 patients with stage I endometrial cancer were included. vNOTES or multiport laparoscopic staging surgery was selected according to each patient's wishes. The primary outcome was the sentinel lymph node (SLN) detection rate, analyzed by a noninferiority test. The secondary outcomes were perioperative outcomes.Among the 120 patients enrolled, 57 underwent vNOTES, and 63 underwent multiport laparoscopy. The patient-specific detection rates of SLNs were 94.73% and 96.82% in the vNOTES and laparoscopy groups, respectively. Additionally, the bilateral detection rates were 82.46% and 84.13%, and the side-specific detection rates were 88.60% and 90.48% in these two groups, respectively. All three detection rates in the vNOTES group were noninferior to those of laparoscopy group at a noninferiority cutoff of -15%. The median operation times of the vNOTES and laparoscopy groups were 132.35 and 138.73 minutes (P=0.362), and the median estimated blood loss were 75 and 50 ml (P=0.096), respectively. No intraoperative complications occurred in either group. The pain scores on the Numerical Rating Scale (NRS) at both 12 hours and 24 hours after operation were significantly lower in the vNOTES group (P<0.001) and the median postoperative hospital stay was significantly shorter in the vNOTES group (P=0.001).This study illustrates the potential applicability of vNOTES in gynecological malignancy surgery by demonstrating its safety and effectiveness in endometrial cancer staging. However, its long-term survival outcomes require further exploration.Copyright © 2023 The Author(s). Published by Wolters Kluwer Health, Inc.

Background. This study was conducted to investigate the effectiveness of vaginal natural orifice transluminal endoscopic surgery (vNOTES) gynecologic scarless surgery in benign and malignant class 2 and class 3 obese patients. Materials and methods. The class 2 and class 3 obese women undergoing vNOTES scarless surgery for benign and malign indications at a tertiary referral medical center between January 2019 and April 2021 were retrospectively analyzed and surgical outcomes were measured. Results. In this study, 81 class 2 and class 3 obese patients underwent gynecological procedures using vNOTES scarless surgery. Of the 81 operations, 55 of the class 2 obese patients with benign pathologies, and 26 of the class 3 obese patients had malign pathologies. No conversion to conventional laparoscopy or even laparotomy was needed in any of the procedures. All of the surgeries were performed by the same surgeon (Prof. Dr Ahmet Kale). vNOTES scarless surgery was performed on 26 class 3 obese patients with malign pathologies. Of the 26 class 3 obese patients, 22 of the class 3 obese patients with early-stage endometrial carcinoma had very high mean body mass index 41.5 kg/m2 (range 20.6–56) and 4 of the class 3 obese patients had ascites with unknown cause and diagnosed with peritoneal carcinomatosis. The mean postoperative pain VAS scores of class 2 obese patients undergoing vNOTES scarless surgery with benign pathology at 6, 12, and 24 h were 3.19, 1.11, and.66, respectively, and the mean postoperative pain VAS scores of class 3 obese patients underwent vNOTES scarless surgery with malign pathology at 6, 12, and 24 h were 3.30, 1.76, and 1.03, respectively. Conclusion. vNOTES scarless surgery is an alternative surgical method for diagnosis and treatment not only in benign obese cases, but also in severely obese patients with early stage endometrial cancer and patients had with ascites with unknown cause. In the near future, vNOTES scarless surgery will become more preferable by experienced surgeons in benign and malignant obese cases as it has increased satisfaction with esthetic results such as less pain, and improved postoperative quality of life in the short and long term.

In 2023, based on advances in the understanding of the pathological and molecular features of endometrial carcinoma, an updated International Federation of Gynaecology and Obstetrics (FIGO) staging system was published, aiming to better define prognostic groups and identify relevant treatment subgroups by including factors reflecting tumour biology (histological subtypes, lymphovascular space invasion, and molecular classification) alongside refinements of anatomical factors (peritoneal carcinomatosis and lymph node metastasis). As part of its mission to improve the quality of care for people with gynaecological cancers, the European Society of Gynaecological Oncology (ESGO), European Society for Radiotherapy and Oncology (ESTRO), and the European Society of Pathology (ESP) updated the ESGO-ESTRO-ESP evidence-based guidelines published in 2021 by incorporating this revised FIGO staging and the large body of new evidence addressing the management of endometrial carcinoma. The development process of these guidelines was based on a systematic literature review and critical appraisal process involving an international multidisciplinary development group consisting of 30 experts from relevant disciplines (gynaecological oncology, radiation oncology, medical oncology, and pathology). A patient representative was also included. Before publication, the guidelines were reviewed by 225 independent international practitioners in cancer care delivery and three patient representatives from Asia, Europe, North Africa, North America, the Middle East, and South America to ensure a global perspective. These guidelines comprehensively cover diagnosis, management, follow-up, and patient education. Management includes surgical and adjuvant therapy according to the stage of the disease, and metastatic and recurrent disease. The management algorithms and the principles of radiotherapy and pathological evaluation are also defined.Copyright © 2025 Elsevier Ltd.

The purpose of this study was to assess the feasibility and efficacy of transvaginal natural orifice transluminal endoscopic surgery (v‐NOTES) staging surgery for extreme obese patients with early‐stage type‐1 endometrial cancer.

This study aims to investigate the survival impact of minimally invasive surgery on endometrial cancer (EC) patients with different histology and microsatellite status.This is a retrospective study based on the Cancer Genome Atlas (TCGA) data. 519 eligible EC patients were divided into four subgroups according to histology and microsatellite status. Kaplan-Meier survival analyses were conducted in all patients and four subgroups to compare the survival outcome after two surgeries (open vs. minimally invasive). Propensity score matching and propensity score covariate adjustment models were used to control confounders. To establish survival prediction models for EC patients, multivariate stepwise Cox regressions were conducted.Among the eligible patients, 318 (61.3%) received open surgery and 201 (38.7%) received minimally invasive surgery. Overall survival was similar between the two groups (p = 0.33), but the latter showed significantly shorter recurrence-free survival (RFS) (p = 0.005). Subgroup analyses revealed the survival influence of surgical approach was only significant in microsatellite-stable (MSS) endometrioid EC patients. These results were verified by Kaplan-Meier survival analyses after propensity score matching and propensity score covariate adjustment models. Finally, the survival influence of multiple clinicopathological factors was analyzed. After stepwise Cox regressions, minimally invasive surgery was found to be independent risk factor for shorter RFS of all patients (hazard ratio [HR] = 2.038, 95% confidence interval [CI] 1.111-3.741, p = 0.02) and MSS patients (HR = 2.449, 95% CI 1.064-5.639, p = 0.04).Minimally invasive surgery is associated with more rapid recurrence in MSS endometrioid EC patients, thus indicating the necessity of microsatellite testing for guiding EC surgery.Copyright © 2020.

Initial results by Le and colleagues, which were published in the June 25, 2015 issue of the New England Journal of Medicine, report significant responses of cancers with microsatellite instability (MSI) to anti-PD-1 inhibitors in patients who failed conventional therapy. This finding fits into a broader body of research associating somatic hypermutation and neoepitope formation with response to immunotherapy, with the added benefit of relying on a simple, widely used diagnostic test. This review surveys the pathogenesis and prognostic value of MSI, diagnostic guidelines for detecting it, and the frequency of MSI across tumors, with the goal of providing a reference for its use as a biomarker for PD-1 blockade. MSI usually arises from either germline mutations in components of the mismatch repair (MMR) machinery (MSH2, MSH6, MLH1, PMS2) in patients with Lynch syndrome or somatic hypermethylation of the MLH1 promoter. The result is a cancer with a 10- to 100-fold increase in mutations, associated in the colon with poor differentiation, an intense lymphocytic infiltrate, and a superior prognosis. Diagnostic approaches have evolved since the early 1990s, from relying exclusively on clinical criteria to incorporating pathologic features, PCR-based MSI testing, and immunohistochemistry for loss of MMR component expression. Tumor types can be grouped into categories based on the frequency of MSI, from colorectal (20%) and endometrial (22%-33%) to cervical (8%) and esophageal (7%) to skin and breast cancers (0%-2%). If initial results are validated, MSI testing could have an expanded role as a tool in the armamentarium of precision medicine.©2016 American Association for Cancer Research.

The aim was to describe the rate of laparoscopic trocar-related subcutaneous tumor implants in women with underlying malignant disease.An analysis of a prospective database of all patients undergoing transperitoneal laparoscopic procedures for malignant conditions performed by the gynecologic oncology service.Between July 1991 and April 2007, laparoscopic procedures were performed in 1694 patients with a malignant intraabdominal condition and in 505 breast cancer patients undergoing risk-reducing, diagnostic or therapeutic laparoscopic procedures without intraabdominal disease. Port-site metastases were documented in 20 of 1694 patients (1.18%) who underwent laparoscopic procedures for a malignant intraabdominal condition. Of these, 15 patients had a diagnosis of epithelial ovarian or fallopian tube carcinoma, 2 had breast cancer, 2 had cervical cancer, and 1 had uterine cancer. Nineteen of 20 patients (95%) had simultaneous carcinomatosis or metastases to other sites at the time of port-site metastasis. Patients who developed port-site metastases within 7 months from the laparoscopic procedure had a median survival of 12 months whereas patients who developed port-site metastasis >7 months had a median survival of 37 months (P=0.004). No port-site recurrence was documented in patients undergoing risk-reducing, diagnostic or therapeutic laparoscopic procedures for breast cancer without intraabdominal disease.The rate of port-site tumor implantation after laparoscopic procedures in women with malignant disease is low and almost always occurs in the setting of synchronous, advanced intraabdominal or distant metastatic disease. The presence of port-site implantation is a surrogate for advanced disease and should not be used as an argument against laparoscopic surgery in gynecologic malignancies.

Desmoid tumors are rare; however, they sometimes form in the abdominal wall after surgery or trauma. We report a case of desmoid tumors in the abdominal wall mimicking port-site metastasis after laparoscopic surgery for endometrial cancer. A 53-year-old woman with familial adenomatous polyposis presented to our hospital with vaginal bleeding and was diagnosed with endometrial cancer. We performed a total laparoscopic hysterectomy and began observation. Two years after surgery, follow-up computed tomography revealed three nodules with a size of approximately 15 mm in the abdominal wall at the trocar sites. Tumorectomy was performed because endometrial cancer recurrence was suspected, but desmoid fibromatosis was finally diagnosed. This is the first report of desmoid tumors at the trocar site after laparoscopic surgery for uterine endometrial cancer. Gynecologists should be aware of this disease because differentiating it from metastatic recurrence is challenging.Copyright: © 2023 Gynecology and Minimally Invasive Therapy.

Background: Port site metastasis (PSM) has been reported as a rare metastasis in women with endometrial carcinoma (EC). However, even more rarely, it has also been described in patients with low- or intermediate-risk EC. Unfortunately, knowledge appears limited on the topic. Objectives: Our objective was to systematically review the literature on PSM in low- or intermediate-risk EC. Search Strategy: A systematic review of the literature was performed by searching six electronic databases from their inception to January 2023. Selection Criteria: We included in our research all peer-reviewed studies which reported PSM in low- or intermediate-risk EC women. Data Collection and Analysis: Data on PSM were collected from the included studies and compared. Results: Seven studies with 13 patients (including our case) were included in the systematic review. PSM was reported in patients with low- or intermediate-risk EC independently from tumor histologic characteristics, endoscopic approach, lymph node staging type, number and site of the port, route of specimen removal, prevention strategies for PSM, and concomitant metastases. Among several proposed treatments, local resection and radiotherapy with or without chemotherapy might be the most appropriate ones. Nevertheless, the prognosis appears poor. Conclusions: In patients with low- or intermediate-risk EC, PSM can occur as a rare metastasis, regardless of tumor characteristics or surgical strategy. Unfortunately, no consensus has been reached regarding treatment, and the prognosis appears poor. Additional cases are needed in order to confirm and further explore this rare EC metastasis.

Port site metastasis (PSM) is considered an uncommon and rare complication in gynecologic malignancies with unclear treatment recommendations or guidelines. Thus, we report the treatment strategies and outcomes of two cases of PSMs following gynecologic malignancies and a review of the literature to provide much information about the most frequent sites of PSMs and the incidence of PSMs in different gynecological tumors. A 57-year-old woman underwent laparoscopic radical surgery for right ovarian serous carcinoma in June 2016 followed by postoperative chemotherapy. Because PSMs were present near the port site of the bilateral iliac fossa, the tumors were completely removed on August 4, 2020, and the patient received chemotherapy. She has shown no signs of relapse. During the same period, a 39-year-old woman underwent laparoscopic type II radical hysterectomy for endometrial adenocarcinoma involving the endometrium and cervix on May 4, 2014, without adjuvant treatment. In July 2020, a subcutaneous mass under her abdominal incision was removed, and chemotherapy plus radiotherapy was administered. Metastasis was found in the left lung in September 2022, but there was no abnormality in the abdominal incision. We showed the two cases of PSMs, reviewed articles to provide some new insights about the incidences of PSMs in the gynecologic tumors, and discussed the proper preventive strategies.© 2023 Yu et al.

The exfoliation of endometrial carcinoma might intraperitoneally spread through the fallopian tube. We analyzed the influence of prior tubal ligation (TL) in endometrial carcinoma to evaluate whether it can prevent the process and improve patients' survival.A total of 562 patients with a diagnosis of endometrial carcinoma at the Peking University People's Hospital between July 1995 and June 2012 were enrolled in this study. The patients were divided into 2 groups based on the presence or absence of prior TL. International Federation of Gynecology and Obstetrics stage distributions, recurrence rates, survival status, and histopathological findings were compared between the 2 groups. Kaplan-Meier estimates and log-rank tests were used to compare the survival status based on TL in the overall population and stratified by histopathological subtypes and International Federation of Gynecology and Obstetrics stages. Cox models analysis was used to estimate the hazard ratios and 95% confidence intervals for associations between TL and carcinoma-specific mortality. All statistical tests were 2-sided.Of the 562 patients, 482 (85.7%) had a diagnosis of endometrioid and 80 patients (14.2%) with nonendometrioid carcinoma. Tubal ligation was associated with negative peritoneal cytology in the total population (P = 0.015) and in patients with endometrioid carcinomas (P = 0.02) but not help to reduce carcinoma-specific mortality (P = 0.095 and P = 0.277, respectively). In the nonendometrioid group, TL was not only associated with negative peritoneal cytology (P = 0.004) but also with lower stage (P < 0.001) and lower recurrence rate(P < 0.005), resulting in improved prognosis (P = 0.022). In Cox models analysis adjusted for covariates, TL was inversely associated with lower endometrial carcinoma-specific mortality (hazard ratio, 0.47; 95% confidence interval, 0.14-2.6).Tubal ligation was associated with lower positive peritoneal cytology, stages, and recurrence rate, and improved prognosis among patients with nonendometrioid carcinoma. Tubal ligation might influence metastatic spread of nonendometrioid endometrial carcinoma. It could also help to reduce positive peritoneal cytology among patients with endometrioid carcinoma, but lacked prognostic significance.

The objective of this study was to find readily ascertainable intraoperative pathologic indicators that would discriminate a subgroup of early corpus cancers that would not require lymphadenectomy or adjuvant radiotherapy.Between 1984 and 1993, a total of 328 patients with endometrioid corpus cancer, grade 1 or 2 tumor, myometrial invasion < or =50%, and no intraoperative evidence of macroscopic extrauterine spread were treated surgically. Pelvic lymphadenectomy was performed in 187 cases (57%), and nodes were positive in nine cases (5%). Adjuvant radiotherapy was administered to 65 patients (20%). Median follow-up was 88 months.The 5-year overall cancer-related and recurrence-free survivals were 97% and 96%, respectively. Primary tumor diameter and lymphatic or vascular invasion significantly affected longevity. No patient with tumor diameter < or =2 cm had positive lymph nodes or died of disease.Patients who have International Federation of Gynecology and Obstetrics grade 1 or 2 endometrioid corpus cancer with greatest surface dimension < or =2 cm, myometrial invasion < or =50%, and no intraoperative evidence of macroscopic disease can be treated optimally with hysterectomy only.

Adenocarcinoma of the endometrium (also known as endometrial cancer, or more broadly as uterine cancer or carcinoma of the uterine corpus) is the most common malignancy of the female genital tract in the United States. It is estimated that 65,950 new uterine cancer cases will have occurred in 2022, with 12,550 deaths resulting from the disease. Endometrial carcinoma includes pure endometrioid cancer and carcinomas with high-risk endometrial histology (including uterine serous carcinoma, clear cell carcinoma, carcinosarcoma [also known as malignant mixed Müllerian tumor], and undifferentiated/dedifferentiated carcinoma). Stromal or mesenchymal sarcomas are uncommon subtypes accounting for approximately 3% of all uterine cancers. This selection from the NCCN Guidelines for Uterine Neoplasms focuses on the diagnosis, staging, and management of pure endometrioid carcinoma. The complete version of the NCCN Guidelines for Uterine Neoplasms is available online at NCCN.org.

A European consensus conference on endometrial carcinoma was held in 2014 to produce multi-disciplinary evidence-based guidelines on selected questions. Given the large body of literature on the management of endometrial carcinoma published since 2014, the European Society of Gynaecological Oncology (ESGO), the European SocieTy for Radiotherapy and Oncology (ESTRO), and the European Society of Pathology (ESP) jointly decided to update these evidence-based guidelines and to cover new topics in order to improve the quality of care for women with endometrial carcinoma across Europe and worldwide.© IGCS and ESGO 2021.

Gastric cancer ranks as the fifth most frequently diagnosed cancer and the seventh most prevalent overall. The lifetime risk of developing gastric cancer is 1.87% for males and 0.79% for females worldwide.This systematic review and meta-analysis aimed to determine whether Extensive Intraoperative Peritoneal Lavage (EIPL) provides short-term benefits or improved survival outcomes for patients undergoing gastrectomy.A comprehensive search spanned PubMed, Embase, Cochrane Library, clinicaltrials.gov, and Web of Science, from their inception up to October 2023, adhering to predefined inclusion and exclusion criteria. The quality of the studies was analyzed using the Cochrane Collaboration Risk of Bias Tool. Data analysis was done using Review Manager 5.3, utilizing a random-effects model.Our analysis incorporated seven randomized controlled trials with 2602 patients. The follow-up time for all outcomes varied from 30-60 months. For our primary outcomes, EIPL demonstrated a significant benefit over surgery alone in terms of recurrence (RR=0.73; 95% CI: 0.65 to 0.83, P<0.00001) and postoperative complications (RR=0.67; 95% CI: 0.51 to 0.87, P=0.003). For our secondary outcomes, postoperative hospital stay (MD=-0.35; 95% CI: -1.11 to 0.41; P-value=0.37), 3-year overall survival (OR=1.44; 95% CI 0.84 to 2.47; P-value=0.19), 3-year disease-free survival (HR=0.93; 95% CI: 0.78 to 1.13; P-value=0.48), and time to first flatus (MD=-0.17; 95% CI: -0.35 to 0.01; P-value=0.06), no statistically significant differences were observed between the EIPL and control groups.While there is a marginal difference in survival outcomes, EIPL holds promise in significantly reducing overall cancer recurrence and suggests an enhancement in postoperative recovery.Copyright © 2024 The Author(s).

Peritoneal invasion is more common and has a worse prognosis in gastric cancer than most of other intestinal cancers. Advanced gastric cancers have a poor course in terms of the development of peritoneal carcinomatosis and prognosis, even if the curative resection has been performed. Patients usually die within the first 2 years of the postoperative period mainly due to peritoneal metastasis. It is, therefore, essential to eradicate intraperitoneal free cancer cells to prevent peritoneal recurrences. A standard therapy has not been developed yet for patients with gastric cancer with a positive peritoneal cytology or a gross peritoneal metastasis. Curative resection following neoadjuvant chemotherapy, postoperative oral S-1 chemotherapy, intraoperative intraperitoneal chemotherapy (IPC), and extensive intraoperative peritoneal lavage (EIPL)-IPC are recommended as therapeutic approaches. Although there is a limited number of studies on EIPL, which is a promising and exciting method in this patient population, unexpected results of survival have been demonstrated. We consider that the results of ongoing and further studies would lead to an extensive use of EIPL, which is a simple and easy method which can be applied anywhere and anytime, in patients with advanced gastic cancer and/or peritoneal cytology positive but peritoneal metastasis negative (CY+/P0) gastric cancer.

This systematic review identifies, evaluates, and summarises the findings of all relevant individual studies on the prevalence of BRCA mutation (BRCAm) in endometrial cancer patients and the incidence of endometrial cancer in BRCAm women patients. Consequently, the benefits and limits of a prophylactic hysterectomy at the time of the risk-reducing salpingo-oophorectomy are analysed and discussed. A systematic literature search was performed in the databases of PubMed, Cochrane, and Web of Science until May 2022; 13 studies met the eligibility criteria. Overall, 1613 endometrial cancer patients from 11 cohorts were tested for BRCA1/2 mutation. BRCA1/2m were identified in 4.3% of women with endometrial cancer (70/1613). BRCA1m was the most represented (71.4%) pathogenic variant. Alongside, a total of 209 BRCAm carriers from 14 studies were diagnosed with endometrial cancer. Only 5 out of 14 studies found a correlation between BRCAm and an increased risk of endometrial cancer. Nevertheless, two studies found a statistical difference only for BRCA1m women. The present systematic review does not provide strong evidence in favour of performing routine hysterectomy at the time of risk-reducing salpingo-oophorectomy; however, it provides epidemiological data that can be useful for counselling patients in order to offer a tailored approach.

The clinical management of BRCA1 and BRCA2 mutation carriers requires accurate, prospective cancer risk estimates.To estimate age-specific risks of breast, ovarian, and contralateral breast cancer for mutation carriers and to evaluate risk modification by family cancer history and mutation location.Prospective cohort study of 6036 BRCA1 and 3820 BRCA2 female carriers (5046 unaffected and 4810 with breast or ovarian cancer or both at baseline) recruited in 1997-2011 through the International BRCA1/2 Carrier Cohort Study, the Breast Cancer Family Registry and the Kathleen Cuningham Foundation Consortium for Research into Familial Breast Cancer, with ascertainment through family clinics (94%) and population-based studies (6%). The majority were from large national studies in the United Kingdom (EMBRACE), the Netherlands (HEBON), and France (GENEPSO). Follow-up ended December 2013; median follow-up was 5 years.BRCA1/2 mutations, family cancer history, and mutation location.Annual incidences, standardized incidence ratios, and cumulative risks of breast, ovarian, and contralateral breast cancer.Among 3886 women (median age, 38 years; interquartile range [IQR], 30-46 years) eligible for the breast cancer analysis, 5066 women (median age, 38 years; IQR, 31-47 years) eligible for the ovarian cancer analysis, and 2213 women (median age, 47 years; IQR, 40-55 years) eligible for the contralateral breast cancer analysis, 426 were diagnosed with breast cancer, 109 with ovarian cancer, and 245 with contralateral breast cancer during follow-up. The cumulative breast cancer risk to age 80 years was 72% (95% CI, 65%-79%) for BRCA1 and 69% (95% CI, 61%-77%) for BRCA2 carriers. Breast cancer incidences increased rapidly in early adulthood until ages 30 to 40 years for BRCA1 and until ages 40 to 50 years for BRCA2 carriers, then remained at a similar, constant incidence (20-30 per 1000 person-years) until age 80 years. The cumulative ovarian cancer risk to age 80 years was 44% (95% CI, 36%-53%) for BRCA1 and 17% (95% CI, 11%-25%) for BRCA2 carriers. For contralateral breast cancer, the cumulative risk 20 years after breast cancer diagnosis was 40% (95% CI, 35%-45%) for BRCA1 and 26% (95% CI, 20%-33%) for BRCA2 carriers (hazard ratio [HR] for comparing BRCA2 vs BRCA1, 0.62; 95% CI, 0.47-0.82; P=.001 for difference). Breast cancer risk increased with increasing number of first- and second-degree relatives diagnosed as having breast cancer for both BRCA1 (HR for ≥2 vs 0 affected relatives, 1.99; 95% CI, 1.41-2.82; P<.001 for trend) and BRCA2 carriers (HR, 1.91; 95% CI, 1.08-3.37; P=.02 for trend). Breast cancer risk was higher if mutations were located outside vs within the regions bounded by positions c.2282-c.4071 in BRCA1 (HR, 1.46; 95% CI, 1.11-1.93; P=.007) and c.2831-c.6401 in BRCA2 (HR, 1.93; 95% CI, 1.36-2.74; P<.001).These findings provide estimates of cancer risk based on BRCA1 and BRCA2 mutation carrier status using prospective data collection and demonstrate the potential importance of family history and mutation location in risk assessment.

Endometrial cancer is the most common gynecologic malignancy in developed country. Women under the age of 40 represent 5% of all endometrial cancer and the majority are nulliparous at the time of diagnosis. The aim of this review was to compare oncologic and fertility outcomes among different fertility-preserving therapies in patients under 45 years of age with grade 1 or 2 endometrial cancer. A systematic review was conducted, the MEDLINE, EMBASE, and CINAHL databases were searched for articles published during the period from January 2010 through January 2020 in accordance with PRISMA guidelines, using the terms endometrial cancer, fertility sparing treatment and conservative treatment. A total of 661 patients in 38 studies were included. The median age was 32.3 years (range 13--43). Regardless of the primary treatment, it is always accompanied by systemic or local hormonal treatment. The median follow-up time was 47.92 months (range 1-412), 54.9 months (range 3.4-412) for the progesterone group, 38.97 months (range 3-172) for the hysteroscopic resection group and 23.11 months (range 1-115.5) for the Levonorgestrel Intrauterine Device group. The overall complete response rate was 79.4%, [Hysteroscopic Resection: 90%, hormonal treatment: 77.7%, and Levonorgestrel Intrauterine Device: 71.3%] The p = 0.02 when the primary treatment is Hysteroscopic resection, always followed by hormonal therapy either oral progesterone or Levonorgestrel Intrauterine Device. Patients who had tumor resection had lower progression than those who received hormonal treatment or Levonorgestrel Intrauterine Device 3.5% vs. 12.1% vs. 19.5% respectively (p = 0.03). The complete response time was higher in the Hysteroscopic Resection group (p = 0.04) with fewer patients undergoing hysterectomy (p = 0.0001). Patients who underwent Hysteroscopic Resection had higher pregnancy rates compared to medical treatment or Levonorgestrel Intrauterine Device, 34.5%, 27.6% and 18.4%, respectively (p = 0.002). CONCLUSION: Patients who underwent Hysteroscopic Resection followed progestogens agent was associated to a better complete response, high pregnancy rates and minor numbers of hysterectomies.Copyright © 2021 Elsevier Inc.

Our objective was to conduct a systematic review and meta‐analysis of studies evaluating the oncological and reproductive outcomes of patients with endometrial atypical hyperplasia (AH) and endometrioid endometrial cancer (EEC) undergoing conservative therapy with hysteroscopic resection (HR).

Endometrial cancer is the most common gynecological malignancy with a relatively good overall prognosis. It traditionally has two subtypes: type 1 (endometrioid carcinoma) and type 2 (non-endometrioid carcinoma). The prognosis is excellent for stage I endometrioid cancer, with a 5-year survival rate of 96%. However, the prognosis is much worse for women with high-risk endometrial cancer. Effective preoperative staging is important in order to tailor treatment and achieve optimal long-term survival. The majority of asymptomatic polyps detected by ultrasound are treated surgically. Conventionally, dilatation and curettage was performed to obtain a histological diagnosis, but nowadays hysteroscopy with biopsy is starting to be considered as the gold standard. Hysteroscopic resection seems to reduce the risk of underdiagnosed (atypical endometrial hyperplasia) endometrial cancer. To avoid the spread of malignant cells, hysteroscopy should be performed with concern to keep intrauterine pressure low. In comparison with cervical injection, the hysteroscopic method has a better detection rate in the para-aortic area during sentinel lymph node mapping. In the assessment of cervical involvement, the accuracy of magnetic resonance imaging is significantly higher than the accuracy of hysteroscopy. In fertility-sparing cases, hysteroscopic endometrium resection with progesterone therapy is an acceptable option.

Endometrial assessment by means of biopsy or sampling of endometrial cells is a minimally invasive alternative for dilatation and curettage (D&C) or hysteroscopy. The use of this technique is believed to reduce the cost of the diagnostic work-up for abnormal uterine bleeding without reducing accuracy. Because the authors were not aware of any systematic review of this test, they performed a meta-analysis to assess the accuracy of endometrial sampling devices in the detection of endometrial carcinoma and atypical hyperplasia.The authors searched the literature for studies published between 1966 and 1999 comparing the results of endometrial sampling with findings at D&C, hysteroscopy, and/or hysterectomy. They found 39 studies that included 7914 women. For each study, the fraction of patients was calculated in which endometrial sampling failed. Furthermore, the authors calculated the fraction of cases of endometrial carcinoma and atypical hyperplasia that were identified correctly as well as the fraction of women in whom these diseases were diagnosed false positively.The detection rate for endometrial carcinoma was higher in postmenopausal women compared with premenopausal women. In both postmenopausal and premenopausal women, the Pipelle was the best device, with detection rates of 99. 6% and 91%, respectively. For the detection of atypical hyperplasia, there was only one study that reported explicitly on postmenopausal women, thereby hampering the possibility of subgroup analysis. Again, the Pipelle was the most sensitive technique with a sensitivity of 81%. The specificity of all devices was > 98%.Endometrial biopsy with the Pipelle is superior to other endometrial techniques in the detection of endometrial carcinoma and atypical hyperplasia. The accuracy of the Pipelle is higher in postmenopausal women compared with premenopausal women.Copyright 2000 American Cancer Society.

This study aimed to compare the quality of histological endometrial samples collected through Pipelle aspiration and hysteroscopic biopsies to assess the agreement between these 2 biopsies in the histological diagnosis of malignancy and to compare the costs of both biopsies.
