The purpose of this study was to evaluate the prognostic factors of patients with stage IIIC1r cervical cancer who underwent concurrent chemoradiotherapy.

To assess the risk factors of lymph node metastasis (LNM) in patients with FIGO stage (2009) IB1 cervical cancer (CC).

Pelvic lymphadenectomy, which is the routine surgical treatment for early-stage cervical cancer, causes serious morbidity. The goal of the current retrospective study was to identify predictive factors of lymph node metastasis (LNM) in patients with early-stage cervical cancer.The study included 496 patients diagnosed with stages IA2-IB1cervical cancer who underwent a radical hysterectomy with pelvic lymphadenectomy. The predictive factors of LNM were evaluated.The incidence of LNM in this study was 4.6%. LNM was more common in patients with deep stromal invasion (DSI), tumor size > 2 cm, lymph vascular invasion and parametrial involvement (PI). Multivariate analysis showed DSI (p = 0.010) and PI (p = 0.005) were independently associated with LNM. The median follow-up time was 56.9 months. The patients with LNM had poorer 5-year overall survival (77.8%; 95% confidence interval (CI) 44.2-92.6) than the patients without LNM (98.2%; 95% CI 95.6-99.2; p = 0.002) and also poorer 5-year recurrence-free survival (65.5%; 95% CI 38.6-82.8) than the patients without LNM (90.2%; 95% CI 86.5-92.9; p < 0.001).The predictive factors of pelvic lymph node metastasis in stage IA2-IB1 cervical cancer patients were DSI and PI. LNM was associated with poorer oncological outcomes.© 2018 S. Karger GmbH, Freiburg.

The role of sentinel lymph node (SLN) biopsy alone for staging of early-stage cervical cancer remains controversial. We aimed to determine the validity of this technique in women with early-stage cervical cancer.We retrospectively reviewed women with early-stage cervical cancer who underwent SLN mapping followed by complete pelvic lymphadenectomy as part of initial surgical management from August 1997 through October 2015. All modes of surgical approach were included. Lymphatic mapping was performed using blue dye, technetium-99m sulfur colloid (Tc-99), and/or indocyanine green (ICG). We determined SLN detection rates, sensitivity and negative predictive value.One hundred eighty-eight patients were included, and 35 (19%) had lymph node metastases. At least one SLN was identified in 170 patients (90%), and bilateral SLNs were identified in 117 patients (62%). The majority of SLNs (83%) were found in the pelvis. There was no difference in detection rates between mapping agents, surgical approach, patients with and without prior conization or between patients with tumors <2cm and ≥2cm. The detection rate for bilateral SLNs was significantly lower in women with body mass index (BMI)>30kg/m than in women with lower BMI (p=0.03). Metastatic disease in sentinel nodes was detected by H&E staining in 78% of cases and required ultrastaging/immunohistochemistry in 22% of cases. Only one patient had a false-negative result, yielding a sensitivity of 96.4% (95% CI 79.8%-99.8%) and negative predictive value of 99.3% (95% CI 95.6%-100%). The false-negative rate was 3.6%.In these women with early-stage cervical cancer, SLN biopsy had very high sensitivity and negative predictive value. We believe it is time to change the standard of care for women with early-stage cervical cancer to SLN biopsy only.Copyright © 2017 Elsevier Inc. All rights reserved.

To evaluate the clinical diagnostic validity of carbon nanoparticle suspension (CNS) in sentinel lymph node biopsy (SLNB) for assessing lymphatic spread of early‐stage cervical cancer.

Sentinel node navigation surgery (SNNS) has been frequently used in early cervical cancer. However, the incidence and potential reduction of lymphatic complications following the removal of the sentinel lymph node remain unknown. Thus, this study aimed to evaluate the occurrence of lymphatic complications post sentinel node navigation surgery in patients with early cervical cancer.A total of 167 patients, including 70 and 97 patients who had undergone SNNS and pelvic lymphadenectomy (PLA), respectively, were enrolled in this study. We compared the lymphatic complications (lower extremity lymphedema and pelvic lymphocele) between the SNNS and PLA groups.The median number of sentinel lymph nodes removed was 2 (range: 1-14). Among the 70 patients in the SNNS group, there were 0 (0%) and 3 (4.3%) occurrences of lower extremity lymphedema and pelvic lymphocele, respectively. The occurrences of lower extremity lymphedema and pelvic lymphocele were significantly lower in the SNNS group than in the PLA group, despite circumflex iliac node removal.The occurrence of lymphatic complications (lower extremity lymphedema and pelvic lymphocele) was significantly lower in the SNNS group than in the PLA group. We found that SNNS, and not PLA, was the best treatment option for preventing the development of lower extremity lymphedema and pelvic lymphocele, despite circumflex iliac node preservation.© The Author(s) 2020.

The purpose of this study was to evaluate the impact of high-risk factors on the survival of patients with cervical cancer treated with surgery followed by adjuvant chemoradiotherapy.From 2000 to 2014, medical records of 897 patients with International Federation of Gynecology and Obstetrics stage IB-IIA disease treated with surgery were retrospectively reviewed. Among them, 483 patients with high-risk factors, including pelvic lymph node metastasis, parametrial invasion, or resection margin involvement, were analyzed.The median follow-up time was 57 months (range, 6-205 months). For patients with single and multiple high-risk factors, the 5-year DFS rates were 80.4% and 65.7%, respectively (p < 0.001), and 5-year OS rates were 87.3% and 75.1%, respectively (p = 0.001). Distant metastasis was the most common pattern of recurrence (86.1%). Furthermore, distant metastasis-free survival significantly differed with the number of high-risk factors present (single 82.7% vs. multiple 68.8%, p < 0.001). In the multivariate analysis, while parametrial invasion and resection margin involvement showed no association, the adenocarcinoma histology, pelvic lymph node metastasis, higher metastatic lymph node ratio, and multiple high-risk factors were independent prognosticators associated with poor DFS and OS.Patients with early-stage cervical cancer having multiple high-risk factors, adenocarcinoma histologic type, and pelvic lymph node metastasis accompanied by a higher lymph node ratio after surgery are more likely to have occult distant metastasis. Further, consolidation with systemic chemotherapy after adjuvant therapy might be considered to improve the survival outcome in this patient population.Copyright © 2020. Published by Elsevier Inc.
