The role of surgery in patients with initially metastatic breast cancer (IMBC) is unclear. The purpose of this study was to determine if surgery improves the prognosis of patients with IMBC.Data of patients with IMBC at the First Affiliated Hospital of Sun Yat-Sen University from 2000 to 2014 were retrospectively analyzed. The last follow-up was October 2015. Clinical characteristics and overall survival (OS) were compared and evaluated by univariate and multivariate analysis.Eighty-one patients were included in this study; 59 were operated and 22 were not. The median survival time was 28 months, 3-year survival rate was 32.5%, and 5-year survival rate was 8.4%. The OS of operated patients was significantly longer than those without surgery (34 vs. 23 months, p=0.002). Surgery (estimated hazard ratio [HR] =0.12, 95% confidence interval [CI]: 0.04-0.42) and endocrine therapy (HR=0.17, 95% CI: 0.06-0.54), were significantly associated with a better prognosis in the multivariate model. However, patients with surgery were younger, had fewer metastases, and a higher ratio of patients with Ki-67≤14%. Patients who were operated more than 3 months after diagnosis had better OS that those who had surgery less than 1 month (p=0.009). Stratified analyses of the surgery group found that younger age (HR 0.28, p=0.016), bone-only metastases (HR 0.24, p=0.006) and chemotherapy administration (HR 0.38, p=0.004) or endocrine therapy (HR 0.06, p=0.006) were favorable predictors of survival. Conclusion Surgery may prolong the OS of patients with IMBC, especially in certain of them, and in those who undergo surgery at a certain time.

Approximately five percent of all breast cancer patients in developed countries present with distant metastases at initial diagnosis. Due to its incurability, metastatic breast cancer is generally treated with systemic therapies to achieve disease control and reduce tumor-related symptoms. Primary treatments for metastatic breast cancer are chemotherapy, endocrine- and biologic therapy, whereas surgery with or without radiotherapy is usually performed to treat impending wound issues. Since 2002, several retrospective non-randomized clinical studies have shown that extirpation of the primary tumor correlates with a significantly improved survival in patients with primary metastatic breast cancer. Others have argued that this survival benefit associated with surgery may be due to selection biases. Therefore, in the absence of published results from randomized controlled trials carried out in India and Turkey and completion of a trial in the United States, there is no clear conclusion on whether surgical excision of the primary breast cancer translates into a survival benefit for patients with de novo metastatic disease. Furthermore, timing and type of surgical procedure, as well as selection of patients who could benefit the most from this approach, represent additional points of uncertainty. Despite the epidemiological burden of this condition, there are no guidelines on how to manage breast cancer patients presenting with de novo metastatic breast cancer; and decisions are often left to provider and patient preferences. Here, we present a critical overview of the literature focusing on the rationale and potential role of primary tumour excision in patients with de novo metastatic breast cancer.

We evaluated patterns of surgical care and their association with overall survival among a contemporary cohort of women with stage IV breast cancer.

Metastatic breast cancer has been defined as a systemic disease. The discussion concerning the resection of lung metastases in patients with breast cancer is controversial. To confirm the role of resection of pulmonary metastases from breast cancer and to identify possible prognostic factors, we reviewed our institutional experience.Between 1991 and 2007, 41 patients with pulmonary metastases from breast cancers underwent complete pulmonary resection. All patients had obtained or had obtainable locoregional control of their primary tumors. Various perioperative variables were investigated retrospectively to confirm the role of metastasectomy and to analyze prognostic factors for overall survival after metastasectomy.All patients were female with a median age of 55 years (range, 35-81 years). The overall survival rate after metastasectomy was 51% at 5 and 10 years. On multivariate analysis, fewer than four pulmonary metastases and a disease-free interval of more than 3 years were significantly favorable prognostic factors for overall survival (p=0.023 and 0.024, respectively).The current practice of pulmonary metastasectomy for breast cancers in our institution was well justified. Pulmonary metastasectomy in patients with previous breast cancer might be justified when fewer than four pulmonary metastases or a disease-free interval of more than 3 years.

We investigated whether overall survival (OS) in patients with primary breast cancer (BC) is prolonged by pulmonary metastasectomy and which prognostic criteria may facilitate the decision in favor of thoracic surgical intervention.We assessed the median OS of 81 women after resection of pulmonary primary BC metastases by means of Kaplan-Meier estimators. Statistical interferences regarding prognostic factors were based on univariate log-rank tests and multivariate Cox proportional hazards regression. Matched patients who had not undergone resection from the Munich Tumor Registry served as controls.Between 1982 and 2007, 81 patients were recruited prospectively. In 81.5% of the patients R0 resection was achieved, which was associated with significantly longer median OS than occurred after R1 or R2 resection (103.4 months versus 23.6 months versus 20.2 months, respectively; p<0.001). Multivariate analysis revealed R0 resection, number (n≥2), size (≥3 cm), and estrogen receptor (ER) and/or progesterone receptor (PR) positivity of metastases as independent prognostic factors for long-term survival. Presence of metastases in mediastinal and hilar lymph nodes correlated with decreased survival only in the univariate analysis (32.1 versus 103.4 months; p=0.095). Matched pair analysis confirmed that pulmonary metastasectomy significantly improved survival.OS in patients with isolated pulmonary primary BC metastasis is prolonged by metastasectomy. Patients with multiple pulmonary lesions or metastases with negative hormone receptor (HR) status are at greater risk of disease relapse and should be followed closely. Moreover, additive treatment tailored to the biological subtype defined by HR expression should be considered for this group.Copyright © 2013 The Society of Thoracic Surgeons.

Isolated lung metastases have been reported to occur in 10-20% of all women with breast carcinoma. The authors described a series of patients who underwent surgery for lung metastases from breast carcinoma.They reviewed the files of 125 consecutive patients who underwent surgery with a curative intent for lung metastases from breast carcinoma between 1972 an 1998 at a single institution. Survival curves were plotted by the Kaplan-Meier method. Prognostic factors were identified using the log-rank test and a Cox proportional hazards model for univariate and multivariate analyses, respectively.The median age at surgery was 53 years. There was a median of 1 resected metastasis (range, 1-16 resected metastases). The median size of the largest metastasis was 19 mm (range, 5-70 mm). The median disease-free interval (DFI) was 3 years. The median follow-up time after surgery was 8.5 years (range, 25 days to 22 years). The 3-year, 5-year, and 10-year probabilities of survival were 58% (95% confidence interval [95% CI], 49-67%), 45% (95% CI, 36-55%), and 30% (95% CI, 21-41%), respectively. The median survival time after surgery was 4.2 years. Complete resection was achieved in 96 patients. The quality of the resection (complete vs. incomplete) was not a statistically significant prognostic factor by univariate analysis and there was no significant difference between these two groups in terms of adjuvant postoperative therapy. The characteristics of the primary tumor and the number of metastases (one vs. two or more) had no detectable influence on survival. The size of the largest metastasis (> 20 mm or < or = 20 mm) and the DFI (< or = 3 years vs. > 3 years) were highly significant prognostic factors (P = 0.006 and P = 0.003, respectively). This was confirmed by multivariate analysis. Patients with a DFI < or = 3 years and/or the largest metastasis > 20 mm reportedly had a poor outcome (median survival, 2.6 years vs. 8.5 years for patients with none of these poor prognostic factors).Resection of lung metastases from breast carcinoma was associated with a significant 5-year survival rate of 45%. Whether these encouraging findings resulted from the surgical procedure itself or the preoperative selection of patients remained uncertain. When surgery is considered in this setting, the size of the largest metastasis and the DFI should be taken into account.

The role of surgery for breast cancer liver metastases (BCLM) remains controversial. This study aimed to analyze survival in patients treated with hepatectomy plus systemic therapy or systemic therapy alone for BCLM and to determine selection factors to guide surgical therapy.Patients who underwent hepatectomy plus systemic therapy (n = 136) and systemic therapy alone for isolated BCLM (n = 763) were compared. Overall survival (OS) was analyzed after propensity score matching. Intrinsic subtypes were defined as: luminal A (estrogen receptor [ER]+ and/or progesterone receptor positive [PR]+, human epidermal growth factor receptor 2 [HER2]-), luminal B (ER and/or PR+, HER2+), HER2-enriched (ER and PR-, HER2+), and basal-like (ER, PR, HER2-).After hepatectomy, independent predictors of poor OS were number and size of liver metastases, and intrinsic subtype (hazard ratios, 1.11, 1.16, and 4.28, respectively). Median OS was 75 and 81 months among patients with luminal B and HER2-enriched subtypes, compared with 17 and 53 months among patients with basal-like and luminal A subtypes (P < .001). Median progression-free survival (PFS) was 60 months with the HER2-enriched subtype, compared with 17, 16, and 5 months with luminal A, luminal B, and basal-like subtypes, respectively (P < .001). After propensity score matching, 5-year OS rates were 56% vs. 40% in the surgery vs. systemic therapy alone groups (P = .018).Surgical resection of BCLM yielded higher OS compared with systemic therapy alone and prolonged PFS among patients with the HER2-enriched subtype. These findings support the use of surgical therapy in appropriately selected patients, based on intrinsic subtypes.Copyright © 2020 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

To determine whether, in a highly selected patient population, medical treatment combined with surgical resection of liver metastases from breast cancer is associated with improved survival compared with medical treatment alone.Between 1988 and 2007, 100 liver resections for metastatic breast cancer were performed at Institut Curie, 51 of which met the criteria for inclusion in this case-control study. With the exception of bone metastases, patients with other distant metastasis sites were excluded. Surgery was only performed in patients with stable disease or disease responding to medical treatment evaluated by imaging evaluation. Surgical cases were individually matched with 51 patients receiving medical treatment only. All patients had 4 or fewer resectable liver metastases. The study group was matched with the control group for age, year of breast cancer diagnosis, time to metastasis, TNM stage, hormone receptor status and breast cancer tumour pathology.Univariate analysis confirmed a survival advantage for patients lacking bone metastases and axillary lymphadenopathy at the time of breast cancer diagnosis and for surgically treated patients. Multivariate analysis indicated that surgery and the absence of bone metastases were associated with a better prognosis. A multivariate Cox model adapted for paired data showed a RR = 3.04 (CI: 1.87-4.92) (p < 0.0001) in favour of surgical treatment.Surgical resection of liver metastases from primary breast cancer appears to provide a survival benefit for highly selected patients.Copyright © 2013 Elsevier Ltd.

Background: Distant metastatic breast cancer (MBC), including metastases found at diagnosis (de novo) and those occurring later (recurrence), represents the most severe form of the disease, when resource utilization is most intensive. Yet, the number of women living with MBC in the United States is unknown. The objective of this article is to use population-based data to estimate the prevalence of MBC.

Despite the increasing use of positron emission tomography/computed tomography (PET/CT) in the management of patients with breast cancer, its role is yet to be defined.We reviewed PET/CT scans carried out in breast cancer patients, the indication, concordance/discordance with other imaging and whether their use had altered patient management.PET/CT scans (233) were carried out in 122 patients between July 2004 and October 2008. Indications were as follows: staging (S) (91), response assessment (RA) (87), clarification (C) of findings on other imaging (32) and reassurance (ASS) (23). In the S group, positive scans were helpful in accurately defining the extent of disease and guided localised or systemic treatment. PET/CT was particularly useful for detecting lytic bone metastases. One-third of the scans was carried out for RA. PET/CT allowed early RA and in some cases appropriate discontinuation of ineffective treatment. PET/CT was used effectively for the clarification of indeterminate lesions on CT (18), magnetic resonance imaging (15) and bone scan (13). In the ASS group, all scans were negative.PET/CT is useful in accurately staging metastatic disease, assessing response to systemic treatment and clarifying equivocation on other imaging. Incorporation of PET/CT in these areas contributes to breast cancer management optimisation.

In the OlympiAD study, olaparib was shown to improve progression-free survival compared with chemotherapy treatment of physician's choice (TPC) in patients with a germline BRCA1 and/or BRCA2 mutation (BRCAm) and human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer (mBC). We now report the planned final overall survival (OS) results, and describe the most common adverse events (AEs) to better understand olaparib tolerability in this population.OlympiAD, a Phase III, randomized, controlled, open-label study (NCT02000622), enrolled patients with a germline BRCAm and HER2-negative mBC who had received ≤2 lines of chemotherapy for mBC. Patients were randomized to olaparib tablets (300mg bid) or predeclared TPC (capecitabine, vinorelbine, or eribulin). OS and safety were secondary end points.A total of 205 patients were randomized to olaparib and 97 to TPC. At 64% data maturity, median OS was 19.3months with olaparib versus 17.1months with TPC (HR 0.90, 95% CI 0.66-1.23; P = 0.513); median follow-up was 25.3 and 26.3months, respectively. HR for OS with olaparib versus TPC in prespecified subgroups were: prior chemotherapy for mBC [no (first-line setting): 0.51, 95% CI 0.29-0.90; yes (second/third-line): 1.13, 0.79-1.64]; receptor status (triple negative: 0.93, 0.62-1.43; hormone receptor positive: 0.86, 0.55-1.36); prior platinum (yes: 0.83, 0.49-1.45; no: 0.91, 0.64-1.33). Adverse events during olaparib treatment were generally low grade and manageable by supportive treatment or dose modification. There was a low rate of treatment discontinuation (4.9%), and the risk of developing anemia did not increase with extended olaparib exposure.While there was no statistically significant improvement in OS with olaparib compared to TPC, there was the possibility of meaningful OS benefit among patients who had not received chemotherapy for metastatic disease. Olaparib was generally well-tolerated, with no evidence of cumulative toxicity during extended exposure.© 2019 THE AUTHORS.

Visual analogue scales (VAS) of sensory intensity and affective magnitude were validated as ratio scale measures for both chronic and experimental pain. Chronic pain patients and healthy volunteers made VAS sensory and affective responses to 6 noxious thermal stimuli (43, 45, 47, 48, 49 and 51 degrees C) applied for 5 sec to the forearm by a contact thermode. Sensory VAS and affective VAS responses to these temperatures yielded power functions with exponents 2.1 and 3.8, respectively; these functions were similar for pain patients and for volunteers. The power functions were predictive of estimated ratios of sensation or affect produced by pairs of standard temperatures (e.g. 47 and 49 degrees C), thereby providing direct evidence for ratio scaling properties of VAS. Vas sensory intensity responses to experimental pain, VAS sensory intensity responses to different levels of chronic pain, and direct temperature (experimental pain) matches to 3 levels of chronic pain were all internally consistent, thereby demonstrating the valid use of VAS for the measurement of and comparison between chronic pain and experimental heat pain.

It was unknown whether surgery for primary tumor would affect the occurrence of local symptoms caused by tumor progression in patients with de novo stage IV breast cancer (BC). Our work attempted to probe the effect of local resection on controlling local symptoms and improving the quality of life in de novo stage IV BC patients.

The aim of this randomized clinical trial was to evaluate the overall survival (OS) data of patients diagnosed with de novo stage IV breast cancer (BC) who received locoregional treatment (LRT) over a 10-year follow-up.

Multiple studies have suggested that resection of the primary tumor improves survival in patients with stage IV breast cancer, yet in the era of targeted therapy, the relation between surgery and tumor molecular subtype is unknown. The objective of the current study was to identify subsets of patients who may benefit from primary tumor treatment and assess the frequency of local disease progression.

The objective of this study was to determine whether the 21-gene Recurrence Score (RS) provides clinically meaningful information in patients with de novo stage IV breast cancer enrolled in the Translational Breast Cancer Research Consortium (TBCRC) 013.

Several prospective studies have evaluated the benefit of primary tumour resection (PTR) in de novo Stage IV breast cancer (BC) patients, but it remains controversial. We aimed to investigate whether PTR improves the survival of de novo stage IV BC patients.

Recent studies indicate that removal of the primary tumour may have a beneficial effect on mortality risk of patients with primary distant metastatic breast cancer (stage IV), although most of them did not rule out confounding by the presence of co-morbidity. In this retrospective study the impact of surgical resection of the primary tumour on the survival of patients with primary distant metastatic disease is investigated, taking into account the presence of co-morbidity and other potential confounders.Between 1993 and 2004, 15 769 patients with breast cancer were diagnosed in the south of the Netherlands. This study included the 728 patients with distant metastatic disease at initial presentation, which was 5% of all patients. Of them, 40% had surgery of the primary tumour. Follow-up was carried out until 1 July 2006.Median survival of the patients who had surgery of their primary tumour was significantly longer than for the patients who did not have surgery (31 vs. 14 months). The 5-year survival rates were 24.5% and 13.1%, respectively (p < 0.0001). In a multivariable Cox regression analysis, adjusting for age, period of diagnosis, T-classification, number of metastatic sites, co-morbidity, use of loco-regional radiotherapy and use of systemic therapy, surgery appeared to be an independent prognostic factor for overall survival (HR = 0.62; 95% CI 0.51-0.76).Removal of the primary tumour in patients with primary distant metastatic disease was associated with a reduction of the mortality risk of around 40%. The association was independent of age, presence of co-morbidity and other potential confounders, but a randomized controlled trial will be needed to rule out residual confounding.

Advanced breast cancer is common in less affluent parts of Asia. The impact of breast surgery on survival of women presenting with metastatic breast cancer in this setting was investigated.Women presenting with metastatic breast cancer at the initial diagnosis at the University Malaya Medical Centre (Malaysia) between 1993 and 2008 were included in the study. Mortality of patients who had primary breast surgery was compared with that of those without surgery, and adjusted for possible confounders by means of a propensity score.Of 3689 patients, 375 (10·2 per cent) presented with metastatic disease. One hundred and thirty-nine patients (37·1 per cent) underwent surgery. A total of 330 deaths occurred during 6814 person-months of follow-up. The 2-year survival rate was 21·2 (95 per cent confidence interval (c.i.) 15·9 to 26·5) per cent in women who did not have surgery and 46·3 (37·7 to 54·9) per cent in those who had breast surgery. Breast surgery was associated with a 28 per cent lower risk of death (hazard ratio 0·72, 95 per cent c.i. 0·56 to 0·94), after adjustment for patient and tumour characteristics, metastatic profile and treatment.Surgical resection of the primary breast tumour was independently associated with a survival advantage in patients presenting with metastatic breast cancer.Copyright © 2011 British Journal of Surgery Society Ltd.

Surgery of the primary tumor usually is not advised for patients with metastatic breast cancer at diagnosis because the disease is considered incurable. In this population-based study, we evaluate the impact of local surgery on survival of patients with metastatic breast cancer at diagnosis.We included all 300 metastatic breast cancer patients recorded at the Geneva Cancer Registry between 1977 and 1996. We compared mortality risks from breast cancer between patients who had surgery of the primary breast tumor to those who had not and adjusted these risks for other prognostic factors.Women who had complete excision of the primary breast tumor with negative surgical margins had a 40% reduced risk of death as a result of breast cancer (multiadjusted hazard ratio [HR], 0.6; 95% CI, 0.4 to 1.0) compared with women who did not have surgery (P =.049). This mortality reduction was not significantly different among patients with different sites of metastasis, but in the stratified analysis the effect was particularly evident for women with bone metastasis only (HR, 0.2; 95% CI, 0.1 to 0.4; P =.001). Survival of women who had surgery with positive surgical margins was not different from that of women who did not have surgery.Complete surgical excision of the primary tumor improves survival of patients with metastatic breast cancer at diagnosis, particularly among women with only bone metastases.

Lung is a common organ of metastases in patients with primary breast cancer. Pulmonary metastasis of primary breast cancer is usually considered as a systemic disease, however, the systemic approaches have achieved little progress in terms of prolonging survival time. In contrast, some studies revealed a probable survival benefit of pulmonary metastasectomy for such patients. However, the prognostic factor for pulmonary metastasectomy in breast cancer patients is still a controversial issue. The aim of this study was to conduct a systematic review and meta-analysis of cohort studies to assess the pooled 5-year overall survival (OS) rate and the prognostic factors for pulmonary metastasectomy from breast cancer.An electronic search in MEDLINE (via PubMed), EMBASE (via OVID), CENTRAL (via Cochrane Library), and Chinese BioMedical Literature Database (CBM) complemented by manual searches in article references were conducted to identify eligible studies. All cohort studies in which survival and/or prognostic factors for pulmonary metastasectomy from breast cancer were reported were included in the analysis. We calculated the pooled 5-year survival rates, identified the prognostic factors for OS and combined the hazard ratios (HRs) of the identified prognostic factors.Sixteen studies with a total of 1937 patients were included in this meta-analysis. The pooled 5-year survival rates after pulmonary metastasectomy was 46% [95% confidence interval (95% CI): 43-49%]. The poor prognostic factors were disease-free interval (DFI) (<3 years) with HR =1.70 (95% CI: 1.37-2.10), resection of metastases (incomplete) with HR =2.06 (95% CI: 1.63-2.62), No. of pulmonary metastases (>1) with HR =1.31 (95% CI: 1.13-1.50) and the hormone receptor status of metastases (negative) with HR =2.30 (95% CI: 1.43-3.70).Surgery with a relatively high 5-year OS rate after pulmonary metastasectomy (46%), may be a promising treatment for pulmonary metastases in the breast cancer patients with a good performance status and limited disease. The main poor prognostic factors were DFI (<3 years), resection of metastases (incomplete), No. of pulmonary metastasis (>1) and hormone receptor status of metastases (negative). And prospective randomized trials will be needed to address these issues in the future.

The role of surgery in breast cancer liver metastases (BCLM) remains elusive, and current application is limited. Our aim is to investigate whether hepatic resection (HR) of BCLM improves survival compared with non-hepatic resection (NHR) treatment.Three hundred and eighty-four patients with BCLM from 2008 to 2018 were divided into two groups. Propensity score matching (PSM) analysis was used to compare the clinical outcomes.After PSM the mean overall survival (OS) and the 1, 3, and 5-year OS rates in HR group were 61.8 months, 92.6%, 54.7% and 54.7%, respectively; while for NHR group these values were 38.6 months, 79.2%, 45.6% and 21.9%, respectively (p < 0.007). Multivariate analysis indicated hormonal receptor status (p = 0.039) and hepatic resection (p = 0.032) were independent prognostic factors.Our study revealed that hepatectomy yields a survival benefit safely compared with medical treatments, especially for patients with positive hormonal receptors.Copyright © 2020 Elsevier Inc.

&lt;b&gt;<i>Background:</i>&lt;/b&gt; The role of liver resection for metastatic breast carcinoma is still debated. &lt;b&gt;<i>Methods:</i>&lt;/b&gt; Fifty-one resected patients were reviewed. All patients received adjuvant chemotherapy after resection of the primary tumor. Clinicopathological characteristics and immunohistochemistry expression of estrogen (ER), progesterone (PR), human epidermal growth factor (HER2), or Ki67 were evaluated. &lt;b&gt;<i>Results:</i>&lt;/b&gt; The median number of metastases was 2; single metastases were present in 24 (47%) patients. The median tumor diameter was 4 cm. Major hepatectomies were performed in 31 (61%) patients. Postoperative mortality was null. Postoperative morbidity was 13.7%. The 1-, 5-, and 10-year survival rates were 92, 36, and 16% respectively. Eleven (21.6%) patients survived longer than 5 years and 8.9% are alive without recurrence 10 years after surgery. At the univariate analysis, tumor diameter, lymph node status, PR receptor status, and triple positive receptors (ER+/PR+/Her2+) were significantly related to survival. At the multivariate analysis, tumor diameter, PR receptor, and triple negative status were significantly related to the long-term outcome. &lt;b&gt;<i>Conclusion:</i>&lt;/b&gt; Liver resection seems to be a safe and effective treatment for metastases from breast cancer, and encouraging long-term survival can be obtained with acceptable risk in selected patients. Tumors less than 5 cm and positive hormone receptor status are the best prognostic factors.

Recent studies suggest local surgical therapy improves survival in metastatic breast cancer (MBC). We evaluate the difference in outcome in patients with MBC after mastectomy versus breast conservation (BCT) and factors that influence outcome.In a retrospective review of our prospective database, we identified patients who presented with MBC (1990 to 2007). Patient surgery type and clinicopathologic factors were reviewed. We compared OS between pts dependent on surgery and clinicopathologic factors.Of the 566 patients with MBC, 154 (27%) underwent removal of the primary tumor. Surgery was associated with an improved OS (33%) versus no surgery (20%) (P = 0.0015). Of those undergoing local therapy; mastectomy was associated with a 37% OS vs BCT with a 20% OS (P = 0.04).Our study confirms that removal of the primary tumor in MBC is associated with improved overall survival. It appears that mastectomy is associated with a significantly improved overall survival.

Contralateral axillary lymph node metastasis (CAM) is an infrequent clinical condition currently considered an M1, stage IV, disease. Due to the absence of shared data on CAM significance and on its therapeutic approach, be it curative or simply palliative, its management is still uncertain and undoubtedly represents a clinical challenge.Patients with pathologically confirmed metachronous CAM were retrospectively evaluated. All patients had been managed at the European Institute of Oncology, Milan, Italy, from 1997. Patients with distant metastases at the time of CAM were excluded. Possible treatments included surgery, systemic therapy and RT (radiotherapy). Outcomes were evaluated as rates of disease-free survival (DFS) and of overall survival (OS).Forty-seven patients with CAM were included in the study. Metachronous CAM occurred 73 months (range 5-500 months) after diagnosis of the primary tumor. The median follow-up time was 5.4 years (interquartile range 2.9-7.0 years). The estimated OS was 72% at 5 years (95% CI 54-83), and 61% at 8 years (95% CI 43-75). The estimated DFS was 61% at 5 years (95% CI 44-74), and 42% at 8 years (95% CI 25-59).These findings, together with those from previous studies, show that CAM outcome, particularly if measured as OS, appear better than at other sites of distant dissemination, when CAM is subjected to surgical and systemic treatments with a curative intent. Therefore, a new clinical scenario is suggested where, in the TNM system, CAM is no longer classified as a stage IV, but as an N3 disease.

The role of supraclavicular lymph node dissection (SCLD) in the treatment of breast cancer with ipsilateral supraclavicular lymph node metastasis (ISLM) remains controversial. We evaluated the role of SCLD in the treatment of breast cancer with ISLM and identified patients who may benefit from SCLD.Data on patients presenting with breast cancer to the Breast Disease Center, Southwest Hospital, The Army Medical University from January 2004 and December 2017 were retrospectively screened. The median duration of follow-up was 36 months (2-175 months). 305 patients who were recently diagnosed with ISLM were eligible for the analysis.Overall, 9,236 women presented with breast cancer during the study period. Among the patients included, 146 and 159 received SCLD with radiotherapy (RT) and RT alone, respectively. Synchronous ISLM without distant metastases were present in 3.6% cases. The 3- and 5-year overall survival (OS) and disease-free survival (DFS) rates were 79.5% and 73.9%, respectively, and 67.5% and 54.8%, respectively. However, SCLD with RT was not associated with superior survival on both univariate and multivariate analyses. On stratified analyses, patients with non-luminal A tumors with 4-9 positive axillary lymph nodes who underwent SCLD with RT had both superior OS (HR =5.296; 95% CI: 1.857-15.107; P=0.001) and DFS (HR =5.331; 95% CI: 2.348-12.108; P<0.001) compared with those who received RT alone.SCLD may not beneficial in improving survival for unselected breast cancer patients with ISLNM. There is less of a tendency to perform SCLD in the luminal A group.2020 Gland Surgery. All rights reserved.

In the era of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)FDG-PET/CT), more patients are being diagnosed with N3M0 disease. The objective of this study was to assess the prognostic impact of radical lymph node surgery (RLNS) in patients with locally advanced breast cancer classified as lymph node N3 disease according to the American Joint Committee on Cancer (AJCC) 2002 in whom there is no known distant metastasis and in the context of multimodal therapy.This was a two-Center retrospective study that included patients with breast cancer classified as N3M0 after (18)FDG-PET/CT assessment. We reviewed the clinical characteristics, surgical treatment and oncological outcomes of those patients.Thirty-nine patients fulfilled the inclusion criteria. Multimodal treatment included neo-adjuvant chemotherapy (n=34), adjuvant radiotherapy (n=33), adjuvant chemotherapy (n=18) or neo- or adjuvant hormone therapy (n=17). Surgical treatment was not homogeneous. Eight patients had undergone RLNS and 31 conventional axillary lymph node dissection (CD). There was no significant difference in median overall survival between the RLNS group and the CD group (32 months (28-36) vs. 49 months (42-56) respectively (p=0.25)). The overall recurrence rate was 23%. Out of the 8 patients who had under gone RLNS, three had relapsed (two with distant metastases and one local).RLNS was not proven to be beneficial in our study. In order to guide surgical management for these patients, PET/CT and magnetic resonance imaging (MRI) could be of interest, therefore a pilot study to improve reproducible surgical management would be of interest.Copyright© 2015 International Institute of Anticancer Research (Dr. John G.

The aim of this study was to investigate the prognosis, patterns of failure, and prognostic factors for breast cancer patients with pathologically proven synchronous ipsilateral supraclavicular lymph node (ISCLN) metastases.We reviewed the records of breast cancer patients with pathologically proven ISCLN metastases. Local aggressive treatment was defined as treatment including surgery, axillary lymph node dissection (ALND), ISCLN excision, radiotherapy (RT), and chemotherapy.A total of 111 patients were included. The 5-year overall survival (OS) and disease-free survival (DFS) rates were 64.2% and 56.2%, respectively. On univariate analysis, RT, ALND, trastuzumab treatment, hormone receptor (HR) status, and local aggressive treatment were identified as significant factors for OS. The 5-year OS for 73 patients who received local aggressive treatment was superior to that of 38 patients who received nonaggressive treatment (70.9% vs. 49.3%, p=0.036). Multivariate analysis showed that RT, HR status, and trastuzumab were significant variables for the 5-year OS and DFS.Multimodality treatment with surgery, taxane-based chemotherapy, hormone therapy, and RT is strongly recommended for breast cancer patients with synchronous ISCLN metastases.

The impact of locoregional treatment (LRT) on overall survival (OS) in de novo metastatic breast cancer (dnMBC) is still under debate, with very few data available regarding exclusive radiotherapy (ERT) as a therapeutic modality.We evaluated the impact of ERT, exclusive surgery, or a combination of surgery plus radiotherapy (bimodality therapy, BMT) on survival outcomes in a national real-life dnMBC cohort. The primary and secondary end points were OS and progression free survival (PFS) according to LRT (ERT, exclusive surgery, BMT) and no LRT. Sensitivity analyses were performed using propensity score matched analyses.From 2008 to 2014, 4507 dnMBC patients were identified. Only patients alive and free from progression under systemic therapy at least 1 year after diagnosis were included (n = 1965). Forty-five percent of patients (891/1965) underwent LRT: 41.1% (n = 366) ERT, 13.7% (n = 122) exclusive surgery, and 45.2% (n = 403) BMT. OS adjusted for major prognostic factors was significantly longer in the ERT and BMT group compared with no-LRT group, but not exclusive surgery (hazard ratio (HR) = 0.63, 95% confidence interval (CI) [0.49, 0.80], p < 0.001, HR = 0.61, 95%CI [0.47, 0.78], p < 0.001 and HR = 0.87, 95%CI [0.61, 1.26], p = 0.466 respectively). Results were similar after matching on a propensity score. ERT, surgery and BMT were all associated with a significantly better PFS in multivariable analysis.ERT was significantly associated with better OS in dnMBC, in the same magnitude as BMT, compared with no-LRT. However, even with statistical models adjusted for known prognostic factors and propensity score analysis, selection biases cannot be eliminated from observational studies.Copyright © 2020 Elsevier B.V.

Stereotactic ablative radiotherapy (SABR) has been reported to be an effective treatment for oligometastatic disease from different primary cancer sites. Here we assess the effectiveness and safety of SABR for oligometastatic breast cancer patients by performing a meta-analysis.Following PRISMA and MOOSE guidelines, a systematic review and meta-analysis was performed. Eligible studies were identified on Medline, Embase, Cochrane Library, and annual meetings proceedings from 1990 to June 2021. A meta-regression analysis was performed to assess if there was a correlation between moderator variables and outcomes, and a p-value < 0.05 was considered significant.Ten studies met criteria for inclusion, comprising 467 patients and 653 treated metastases. The 1- and 2-year local control rates were 97% (95% CI 95 - 99%), and 90% (95% CI 84 - 94%), respectively. Overall survival (OS) was 93% (95% CI 89 - 96%) at 1 year, 81% (95% CI 72 - 88%) at 2 years. The rate of any grade 2 or 3 toxicity was 4.1 % (95% CI 0.1-5), and 0.7% (0-1%), respectively. In the meta-regression analysis, only prospective design (p=0.001) and bone-only metastases (p=0.01) were significantly associated with better OS. In the subgroup analysis, the OS at 2y were significantly different comparing HER2+, HR+/HER2(-) and triple negative breast cancer 100%, 86% and 32%, p=0.001. For local control outcomes, hormone receptor status (p=0.01) was significantly associated on meta-regression analysis.SABR for oligometastatic breast cancer is safe and associated with high rates of local control. Longer follow-up of existing data and ongoing prospective trials will help further define the role of this management strategy.Copyright © 2021 Elsevier B.V. All rights reserved.
