Background: The reverse sequence of neoadjuvant chemotherapy, preoperative radiotherapy, mastectomy then immediate breast reconstruction is currently proposed for selected patients with locally advanced breast cancer. Few studies have compared it to the standard sequence of neoadjuvant chemotherapy, mastectomy and radiotherapy with or without differed reconstruction. Our study compares overall (OS) and recurrence-free (RFS) survivals of breast cancer patients treated with reverse sequence compared to the standard technique., Methods: In this retrospective, single center study at a Comprehensive Cancer Center in France, patients were included if: female, age <65y, had received neoadjuvant chemotherapy, mastectomy and radiotherapy, and were M0. Outcomes for patients treated by reverse sequence (RS) are compared to those for patients treated by standard sequence (ST). Data was collected from medical records., Results: From January 2009 to April 2018, 222 eligible patients were treated, 46 by RS and 176 by ST. Mean follow-up was 61.7 months. Five-year OS and RFS did not differ between groups. 5-yr OS: 88.4% 95%CI [74.1-95.0] for RS and 81.5% 95%CI [74.0-87.0] for ST (P = 0.4412); 5-yr RFS: 78.3% 95%CI [61.9-88.3] for RS and 70.1% 95%CI [62.2-76.7] for ST (P = 0.3003). Overall treatment time was significantly shorter in the RS group, and the rate of severe surgical complications did not differ between groups., Conclusions: For locally advanced breast cancer patients with an indication for radiation therapy the reverse sequence offers similar safety and efficacy results as the standard treatment while allowing immediate breast reconstruction. However, careful patient selection is necessary, particularly with regard to preoperative lymph node invasion., Competing Interests: Declaration of competing interest The authors declare no competing interests., (Copyright © 2022 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

The similarities between sporadic basal-like breast cancer (BLBC) and BRCA1-mutated breast tumours raise the possibility that deregulation of the same pathway may underlie these tumour types. The aim of this study was to determine if PTEN aberrations are characteristic of both BRCA1 tumours and sporadic TN breast carcinomas with low BRCA1 expression, and can thus be used to identify sporadic tumours potentially sensitive to PARP inhibitors. Twelve BRCA1 tumours, 19 non-BRCA familial breast tumours and 71 unselected TN breast carcinomas were screened for PTEN mutations and assessed for PTEN expression and BRCA1 mRNA expression. Loss of PTEN expression was observed in 67% of BRCA1 tumours and more specifically in 89% of TN BRCA1 tumours highlighting the link between PTEN loss and BLBC in the context of germline BRCA1 mutations. Regarding unselected TN tumours, 56% showed PTEN expression loss and 35% displayed low BRCA1 mRNA expression. Unlike familial breast cancers with low BRCA1 mRNA expression, no significant correlation was observed between the loss of PTEN expression and low BRCA1 mRNA expression in this unselected TN tumours panel. Our data suggest that, unlike the germinal context, PTEN and BRCA1 alterations in sporadic TN breast tumours are independent events., Competing Interests: Declaration of Competing Interest The authors declare no conflicts of interest., (Copyright © 2022.

Background: We determined the prognostic impact of lymphovascular invasion (LVI) in a large, national, multicenter, retrospective cohort of patients with early breast cancer (BC) according to numerous factors., Patients and Methods: We collected data on 17 322 early BC patients treated in 13 French cancer centers from 1991 to 2013. Survival functions were calculated using the Kaplan-Meier method and multivariate survival analyses were carried out using the Cox proportional hazards regression model adjusted for significant variables associated with LVI or not. Two propensity score-based matching approaches were used to balance differences in known prognostic variables associated with LVI status and to assess the impact of adjuvant chemotherapy (AC) in LVI-positive luminal A-like patients., Results: LVI was present in 24.3% (4205) of patients. LVI was significantly and independently associated with all clinical and pathological characteristics analyzed in the entire population and according to endocrine receptor (ER) status except for the time period in binary logistic regression. According to multivariate analyses including ER status, AC, grade, and tumor subtypes, the presence of LVI was significantly associated with a negative prognostic impact on overall (OS), disease-free (DFS), and metastasis-free survival (MFS) in all patients [hazard ratio (HR) = 1.345, HR = 1.312, and HR = 1.415, respectively; P < 0.0001], which was also observed in the propensity score-based analysis in addition to the association of AC with a significant increase in both OS and DFS in LVI-positive luminal A-like patients. LVI did not have a significant impact in either patients with ER-positive grade 3 tumors or those with AC-treated luminal A-like tumors., Conclusion: The presence of LVI has an independent negative prognostic impact on OS, DFS, and MFS in early BC patients, except in ER-positive grade 3 tumors and in those with luminal A-like tumors treated with AC. Therefore, LVI may indicate the existence of a subset of luminal A-like patients who may still benefit from adjuvant therapy., Competing Interests: Disclosure The authors have declared no conflicts of interest., (Copyright © 2021 The Authors.

Introduction: Women identified as high-risk for breast cancer may choose between close follow-up and radical mastectomy. Prophylactic mastectomy, as any other surgery, is associated with benefits and harms. The aim of this study was to assess the morbidity associated with prophylactic mastectomy and to evaluate the prevalence of occult cancers., Methods: All patients who underwent unilateral or bilateral prophylactic mastectomy between 2007 and 2017 in our institution were eligible for inclusion in this retrospective study. Medical history, type of surgery, occurrence of complication or reoperation and pathological reports were examined in medical charts., Results: 79 women underwent prophylactic mastectomy over the studied period of which 58.2% were contralateral after breast cancer. A genetic mutation was present in 86.1% of cases. Postoperative complications occurred in 43.0% of cases. An additional surgery for medical or esthetic purpose was needed in 72.1% of cases. Occult cancer was found in 11.4% of the pathological reports. Triple negative invasive ductal carcinoma was discovered in two cases (2.5%)., Discussion: Prophylactic mastectomy is the only effective preventive action against breast cancer. Women must be clearly informed of possible complications, high reoperation rate and potential pathological findings. Identifying women most at risk for breast cancer would help to better target those who will benefit most from surgery., (Copyright © 2021 Société Française du Cancer.

Introduction: Ductal carcinoma in situ (DCIS) accounts for 15% of all breast cancers and generally, the prognosis is good if treated optimally. The standard treatment includes breast conservative surgery along with adjuvant radiotherapy. Skin-sparing mastectomy (SSM) preserves the breast skin envelope but its oncological safety poses a few concerns. Moreover, no DCIS-specific studies have compared the local recurrence (LR) rate following total mastectomy (TM) or SSM. We evaluated the LR rate in DCIS patients who underwent either TM or SSM., Methods: This is a retrospective study on women who underwent mastectomy with or without immediate breast reconstruction or secondary reconstruction for pure DCIS of the breast. All patients treated at Institut Bergonié by mastectomy for DCIS from January 1990 to December 2010 were included. LR and overall survival (OS) rates were estimated., Results: The study population included 399 patients who were categorized into two groups, 207 in the TM group and 192 in the SSM group. At 10 years of follow-up, the LR rate was 0.97% in the TM group and 1.04% in the SSM group (p = NS). The OS of the entire population was 94.7% [95% CI; 91.6-96.7], 92.8% [95% CI, 87.9-95.8] for the TM group and 96.8% [95% CI, 91.6-98.8] for the SSM group., Conclusions: In our study, the LR rate following mastectomy is low, regardless of the surgical technique used, with an excellent OS at 10 years., (Copyright © 2019.

Introduction: The aim of this study was to examine changes in therapeutic practices for early breast cancer T0-2 N0 managed by upfront surgery and SLNB., Population: Between 1999 and 2012, 15.508 patients were treated. Four periods were determined: 1999-2003, 2004-2006, 2007-2009 and > 2009. Five tumor subtypes were defined according to hormonal receptors (HR) and Her2: Luminal A (HR + Her2- Grade 1-2), Her2 (Her2+ HR-), Triple-negative (HR- Her2-), Luminal B Her2- (HR + Her2- Grade 3), Luminal B Her2+ (HR + HER2+)., Methods: Rates of axillary lymph node dissection (ALND), adjuvant chemotherapy ± trastuzumab, endocrine treatment, mastectomy and post mastectomy radiotherapy (PMRT) were analyzed according to treatment periods with univariate and multivariate analysis. Overall and disease-free survivals were analyzed according to treatment periods adjusted for HR and then for tumor subtypes., Results: Rates of ALND, adjuvant chemotherapy and endocrine treatment varied significantly according to treatment periods, for HR positive and negative tumors. ALND rate decreased for all tumor subtypes with a decrease of adjuvant chemotherapy rate for Luminal A tumors and an increase for Luminal B Her2+ and Her2-tumors. Endocrine treatment rate decreased for Luminal A and increased for Luminal B Her2+ tumors. In multivariate analysis, these modifications with time remained significant. Mastectomy and PMRT rates increased. In multivariate analysis, overall and disease-free survivals increased during successive periods., Conclusion: A global therapeutic de-escalation in ALND and adjuvant systemic treatment, combined with an actual escalation in some specific subsets was demonstrated, but without negative impact on survival., (Copyright © 2017 Elsevier Ltd.

Introduction: The objective of our study is to describe the practices of breast reconstruction in patients aged 70 years and over undergoing a radical mastectomy at institut Bergonié., Material and Methods: We performed a detailed single-site retrospective study from January 2005 to December 2015. Through a computerized review, we have identified and analyzed all patients aged 70 years and over who underwent a breast reconstruction., Results: Five hundred and ninety patients underwent a radical mastectomy during the period. Twenty-eight patients (4.7%) benefited from a breast reconstruction. Nineteen patients (67.9%) had an immediate breast reconstruction and 9 patients (32.1%) had a delayed breast reconstruction, within an average time of 2 years. Sixteen patients (57.1%) benefited from the insertion of an expander replaced by a permanent implant. Five patients (17.9%) benefited from the immediate placement of an implant. Six patients (21.4%) had a reconstruction by autologous latissimus dorsi flap and 1 patient (3.6%) by exclusive lipofilling. Four patients (14.3%) presented postoperative complications without the need for removal of an implant or flap loss. Twenty patients (71.4%) were satisfied with their final reconstruction., Conclusions: Breast reconstruction in elderly patients is possible. Further studies are needed to better describe French practices., (Copyright © 2017 Société Française du Cancer. Published by Elsevier Masson SAS. All rights reserved.)

Purpose: Controversy exists about the prognosis of breast cancer in young women. Our objective was to describe clinicopathological and prognostic features to improve adjuvant treatment indications., Methods: We conducted a retrospective multi centre study including fifteen French hospitals. Disease-free survival's data, clinical and pathological criteria were collected., Results: 5815 patients were included, 15.6% of them where between 35 and 40 years old and 8.7% below 35. In 94% of the cases, a palpable masse was found in patients ≤35 years old. Triple negative and HER2 tumors were predominantly found in patients ≤35 (22.2% and 22.1%, p < 0.01). A young age ≤40 years (p < 0.001; hazard ratio [HR]: 2.05; 95% confidence limit [CL]: 1.60-2.63) or ≤35 years (p < 0.001; [HR]: 3.86; 95% [CL]: 2.69-5.53) impacted on the indication of chemotherapy. Age ≤35 (p < 0.001; [HR]: 2.01; 95% [CL]: 1.36-2.95) was a significantly negative factor on disease-free survival. Chemotherapy (p < 0.006; [HR]: 0.6; 95% [CL]: 0.40-0.86) and positive hormone receptor status (p < 0.001; [HR]: 0.6; 95% [CL]: 0.54-0.79) appeared to be protector factors. Patients under 36, had a significantly higher rate of local recurrence and distant metastasis compared to patients >35-40 (21.5 vs. 15.4% and 21.8 vs. 12.6%, p < 0.01)., Conclusion: Young women present a different distribution of molecular phenotypes with more luminal B and triple negative tumors with a higher grade and more lymph node involvement. A young age, must be taken as a pejorative prognostic factor and must play a part in indication of adjuvant therapy., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

Aim: Sentinel lymph node (SLN) biopsy was recently recommended after prior breast tumour surgery and lymphadenectomy is not the gold standard anymore for nodal staging after a lesion's removal. The purpose of our study was to evaluate the good practices of use of SLN biopsy in this context., Patients and Methods: From 2006 to 2012, 138 patients having undergone a surgical biopsy without prior diagnosis of an invasive carcinoma with a definitive histological analysis in favour of this diagnosis were included in a prospective observational multicentric study. Each patient had a nodal staging following SLN biopsy with subsequent systematic lymphadenectomy., Results: The detection rate of SLN was 85.5%. The average number of SLNs found was 1.9. The relative detection failure risk rate was multiplied by 4 in the event of an interval of less than 36 days between the SLN biopsy and the previous breast surgery, and by 9 in the event of using a single-tracer detection method. The false negative rate was 6.25%. The prevalence of metastatic axillary node involvement was 11.6%. In 69% of cases only the SLN was metastatic. The post-operative seroma rate was 19.5%., Conclusion: Previous conservative breast tumour surgery does not affect the accuracy of the SLN biopsy. A sufficient interval of greater than 36 days between the two operations could allow to improve the SLN detection rate, although further studies are needed to validate this statement., Clinical Trial Registration Number: NCT00293865., (Copyright © 2016 Elsevier Ltd.

Objectives: To assess the prognostic factors of T1 and T2 infiltrating lobular breast cancers, and to investigate predictive factors of axillary lymph node involvement., Methods: This is a retrospective multicentric study, conducted from 1999 to 2008, among 13 french centers. All data concerning patients with breast cancer who underwent a primary surgical treatment including a sentinel lymph node procedure have been collected (tumors was stage T1 or T2). Patients underwent partial or radical mastectomy. Axillary lymph node dissection was done systematically (at the time of sentinel procedure evaluation), or in case of sentinel lymph node involvement. Among all the 8100 patients, 940 cases of lobular infiltrating tumors were extracted. Univariate analysis was done to identify significant prognosis factors, and then a Cox regression was applied. Analysis interested factors that improved disease free survival, overall survival and factors that influenced the chemotherapy indication. Different factors that may be related with lymph node involvement have been tested with univariate than multivariate analysis, to highlight predictive factors of axillary involvement., Results: Median age was 60 years (27-89). Most of patients had tumours with a size superior to 10mm (n=676, 72%), with a minority of high SBR grade (n=38, 4%), and a majority of positive hormonal status (n = 880, 93, 6%). The median duration of follow-up was 59 months (1-131). Factors significantly associated with decreased disease free survival was histological grade 3 (hazard ratio [HR]: 3,85, IC 1,21-12,21), tumour size superior to 2cm (HR: 2,85, IC: 1,43-5,68) and macrometastatic lymph node status (HR: 3,11, IC: 1,47-6,58). Concerning overall survival, multivariate analysis demonstrated a significant impact of age less than 50 years (HR: 5,2, IC: 1,39-19,49), histological grade 3 (HR: 5,03, IC: 1,19-21,25), tumour size superior to 2cm (HR: 2,53, IC: 1,13-5,69). Analysis concerning macrometastatic lymph node status nearly reached significance (HR: 2,43, IC: 0,99-5,93). There was no detectable effect of chemotherapy regarding disease free survival (odds ratio [OR] 0,8, IC: 0,35-1,80) and overall survival (OR: 0,72, IC: 0,28-1,82). Disease free survival was similar between no axillary invasion (pN0) and isolated tumor cells (pNi+), or micrometastatic lymph nodes (pNmic). There were no difference neither between one or more than one macromatastatic lymph node. But disease free survival was statistically worse for pN1 compared to other lymph node status (pN0, pNi+ or pNmic). Factors associated with lymph node involvement after logistic regression was: age from 51 to 65 years (OR: 2,1, IC 1,45-3,04), age inferior to 50 years (OR 3,2, IC: 2,05-5,03), Tumour size superior to 2cm (OR 4,4, IC: 3,2-6,14), SBR grading 2 (OR 1,9, IC: 1,30-2,90) and SBR grade 3 (OR 3,5, IC: 1,61-7,75)., Conclusion: The analysis of this series of 940 T1 and T2 lobular invasive breast carcinomas offers several information: factors associated with axillary lymph node involvement are age under 65 years, tumor size greater than 20mm, and a SBR grade 2 or 3. The same factors were significantly associated with the OS and DFS. The macrometastatic lymph node involvement has a significant impact on DFS and OS, which is not true for isolated cells and micrometastases, which seem to have the same prognosis as pN0., (Copyright © 2015 Elsevier Masson SAS.

Background: Focusing on the current context of national and international recommendations, techniques development to evaluate and preserve fertility and patients' claims, this study aims to make a survey about the management of patients' breast cancer regarding oncofertility., Methods: Retrospective and analytic study of medical practices at Bergonié Institute of health professionals (medical oncologists, surgical oncologists, nurses) dedicated to the care of non-disseminated breast cancer patients younger than 37, needing medical treatment., Results: The number of participants was 230. The most interested practitioners in fertility theme are those of multidisciplinary consultation and surgeons (P<0.001), with an increasing interest during last years (P<0.05). The information about hypofertilizing risks of treatments are delivered most of the time by oncologists (57.7%). The motherhood project is expressed by 11 patients (4.9%) before treatment, only 4 of them receive information on the risks and 49 patients (21.7%) during follow-up. Only 24 patients (48% of the 49) are encouraged for motherhood., Conclusion: To satisfy patients' requests, several improvements have to be made regarding the patients' information, the health professionals' awareness and care coordination., (Copyright © 2015 Société Française du Cancer.

Women who have undergone surgical treatment for breast cancer often benefit from a contralateral reduction mammaplasty (CRM) aimed at symmetrization of the contralateral breast unaffected by the initial cancer. In our 7-year multicentric study (12 centers) of 2718 patients, incidence of CRM cancers (CRMc) was 1.47% (n = 40) [95% CI 1.05%-2.00%]. The CRMc group had significantly more initial mammary cancers of invasive lobular carcinoma (ILC, 22.5% vs 12.0%) and ductal carcinoma in situ (DCIS, 35.0% vs 21.6%) types than the healthy CRM group (p = 0.017). 35.0% (n = 14) of patients had en bloc resection; 25.0% (n = 10) of surgical specimens were correctly oriented. En bloc resection and orientation of surgical specimens enable precise pinpointing of the CRMc. A salvage lumpectomy may be proposed as an option when margins are invaded. The histological distribution of the 40 CRMc (mean size 12.7 mm) was carcinoma in situ (CIS) 70%, ILC 12.5%, invasive ductal carcinoma (IDC) 12.5% and tubular carcinoma (TC) 5.0%., (Copyright © 2015 Elsevier Ltd.

To define the prognostic value of isolated tumor cells (ITC), micrometastases (pN1mi) and macrometastases in early stage breast cancer (ESBC). We conducted a retrospective multicenter cohort study at 13 French sites. All the eligible patients who underwent SLNB from January 1999 to December 2008 were identified, and appropriate data were extracted from medical records and analyzed. Among 8001 patients, including 70% node-negative (n = 5588), 4% ITC (n = 305), 10% pN1mi (n = 794) and 16% macrometastases (n = 1314) with a median follow-up of 61.3 months, overall survival (OS) and recurrence-free survival (RFS) rates at 84 months were not statistically different in ITC or pN1mi compared to tumor-free nodes. Axillary recurrence (AR) was significantly more frequent in ITC (1.7%) and pN1mi (1.5%) compared to negative nodes (0.6%). Survival and AR rates of single macrometastases were not different from those of ITC or pN1mi. In case of 2 macrometastases or more, survival rates decreased and recurrence rates increased significantly. Micrometastases and ITC do not have a negative prognostic value. Single macrometastases might have an intermediate prognostic value while 2 macrometastases or more are associated with poorer prognosis., (Copyright © 2014 Elsevier Ltd. All rights reserved.)

Background: A subgroup of T1N0M0 breast cancer (BC) carries a high potential of relapse, and thus may require adjuvant systemic therapy (AST)., Patients and Methods: Retrospective analysis of all patients with T1 BC, who underwent surgery from January 1999 to December 2009 at 13 French sites. AST was not standardized., Results: Among 8100 women operated, 5423 had T1 tumors (708 T1a, 2208 T1b and 2508 T1c 11-15 mm). T1a differed significantly from T1b tumors with respect to several parameters (lower age, more frequent negative hormonal status and positive HER2 status, less frequent lymphovascular invasion), exhibiting a mix of favorable and poor prognosis factors. Overall survival was not different between T1a, b or c tumors but recurrence-free survival was significantly higher in T1b than in T1a tumors (P = 0.001). In multivariate analysis, tumor grade, hormone therapy and lymphovascular invasion were independent prognostic factors., Conclusion: Relatively poor outcome of patients with T1a tumors might be explained by a high frequency of risk factors in this subgroup (frequent negative hormone receptors and HER2 overexpression) and by a less frequent administration of AST (endocrine treatment and chemotherapy). Tumor size might not be the main determinant of prognosis in T1 BC.

Background: Pure Tubular Carcinoma (PTC) of the breast is a rare histological subtype of invasive breast cancer characterized by a low rate of lymph node involvement. Currently there is no consensus on less surgical axillary node staging according to this histological subtype., Methods: We performed a retrospective multi-institutional study. Inclusion criteria were PTC, sentinel lymph node detection (SLND) and conservative breast surgery., Results: From January 1999 to December 2006, 234 patients were included in the study from 9 institutions. The median pathological tumor size was 9.59 (1-22) mm. SLN were successfully detected in 98% (229/234) of patients. Among the 234 patients, a macrometastasis was found in 6 cases (2.5%), micrometastasis in 15 cases (6.4%), and isolated cells in 2 cases (0.8%). In the case of patients with SLND macrometastasis, half of them had macrometastasis in the complementary axillary lymphadenectomy, and none in the case of SLN only micrometastasis or isolated cells. Of the 122 patients with a pathological tumor size <10 mm, none had sentinel node macrometastasis. According to a multivariate analysis, pathological tumor size (>10 mm) was the only parameter significatively linked to the risk of lymph node involvement (p = 0.007)., Conclusion: In a large multi-institutional series with SLND, we have shown that the risk of axillary lymph node involvement in PTC is very low. In the case of PTC <10 mm, we suggest that surgical axillary evaluation, even with SLND, may not be warranted., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Objective: Breast cancer is the most frequent secondary tumor for women treated for Hodgkin's disease. It is important to study the risk factors associated to be able to adapt the monitoring of these women., Patients and Methods: This is a retrospective study from Institut Bergonié, a comprehensive French Cancer Center, concerning the women treated for Hodgkin's disease and having developed a breast cancer., Results: Among 328 women treated for Hodgkin's disease between January 1968 and December 1994, 20 patients developed 25 breast cancers. The average age of the patients during the irradiation was 24 years and the average period of occurrence of the cancer was 19 years. An irradiation of the chest wall and an under-diaphragmatic irradiation in doses of 40Gy are risk factors for the occurrence of breast cancer. A young age, less than 30, in the treatment of Hodgkin's disease tend to be significant., Discussion and Conclusion: This population of women with a high risk of breast cancer thus has to benefit from an appropriate monitoring program, which is what we suggest setting up in the Institut Bergonié., (Copyright © 2011 Elsevier Masson SAS.

Background: Our objective was to assess the global cost of the sentinel lymph node detection [axillary sentinel lymph node detection (ASLND)] compared with standard axillary lymphadenectomy [axillary lymph node dissection (ALND)] for early breast cancer patients., Patients and Methods: We conducted a prospective, multi-institutional, observational, cost comparative analysis. Cost calculations were realized with the micro-costing method from the diagnosis until 1 month after the last surgery., Results: Eight hundred and thirty nine patients were included in the ASLND group and 146 in the ALND group. The cost generated for a patient with an ASLND, with one preoperative scintigraphy, a combined method for sentinel node detection, an intraoperative pathological analysis without lymphadenectomy, was lower than the cost generated for a patient with lymphadenectomy [€ 2947 (σ = 580) versus € 3331 (σ = 902); P = 0.0001]., Conclusion: ASLND, involving expensive techniques, was finally less expensive than ALND. The length of hospital stay was the cost driver of these procedures. The current observational study points the heterogeneous practices for this validated and largely diffused technique. Several technical choices have an impact on the cost of ASLND, as intraoperative analysis allowing to reduce rehospitalization rate for secondary lymphadenectomy or preoperative scintigraphy, suggesting possible savings on hospital resources.

Purpose: The risk of non sentinel node (NSN) involvement varies in function of the characteristics of sentinel nodes (SN) and primary tumor. Our aim was to determine and validate a statistical tool (a nomogram) able to predict the risk of NSN involvement in case of SN micro or sub-micrometastasis of breast cancer. We have compared this monogram with other models described in the literature., Methods: We have collected data on 905 patients, then 484 other patients, to build and validate the nomogram and compare it with other published scores and nomograms., Results: Multivariate analysis conducted on the data of the first cohort allowed us to define a nomogram based on 5 criteria: the method of SN detection (immunohistochemistry or by standard coloration with HES); the ratio of positive SN out of total removed SN; the pathologic size of the tumor; the histological type; and the presence (or not) of lympho-vascular invasion. The nomogram developed here is the only one dedicated to micrometastasis and developed on the basis of two large cohorts. The results of this statistical tool in the calculation of the risk of NSN involvement is similar to those of the MSKCC (the similarly more effective nomogram according to the literature), with a lower rate of false negatives., Conclusion: this nomogram is dedicated specifically to cases of SN involvement by metastasis lower or equal to 2 mm. It could be used in clinical practice in the way to omit ALND when the risk of NSN involvement is low., (Copyright © 2011 Elsevier Ltd. All rights reserved.)

Intraoperative examination of sentinel lymph nodes (SLN) in breast cancer can avoid a new surgical procedure in case of positive SLN, but its value, efficacy and the methods used are still controversial. The aim of our study was to evaluate the imprint cytology intraoperative method of SLN analysis performed at our institution. We did a retrospective study of the sentinel lymph node procedures performed during a period of 24  months on cT1N0 unifocal breast cancers. Intraoperative procedure was mainly by imprint cytology (touch prep). A SLN procedure was performed on 187 women with 360 SLN. Two hundred and seventy-seven SLN among 156 women were analyzed intraoperatively by touch prep. 19/48 positive SLN were detected by intraoperative touch prep (sensitivity 39.6%; specificity 100%; positive predictive value 100%; negative predictive value 88.7%, accuracy 89.5%). False negative rate of cytological intraoperative examination of SLN was 11,2% by SLN and 18,3% by patient. By univariate analysis, this rate significantly increased with lymphovascular invasion, tumor size cT1b and c and histological SBR grade 2 or 3. By multivariate analysis, only lymphovascular invasion was a predictive factor of intraoperative touch prep failure (OR = 3.3; IC 1.3-8.4). Intraoperative imprint cytology of SLN in breast cancer is associated with a high rate of false negativity that questions its use in this setting.

Background: Axillary lymph node clearance (ALNC) improves locoregional control and provides prognostic information for early breast cancer treatment, but effects on survival are controversial. This multicentre, randomized pragmatic equivalence trial compares outcomes for post-menopausal early invasive breast cancer patients after locoregional treatment with ALNC and adjuvant therapies to outcomes after locoregional treatment without ALNC and adjuvant therapies., Methods: From 1995-2005, women aged ≥ 50 years with early breast cancer (tumor ≤ 10 mm) and clinically-negative axillary nodes were randomized to receive treatment with ALNC (Ax) or without (no-Ax). Adjuvant therapies were prescribed according to hormonal receptor status and individual histological results. The primary endpoint was overall survival (OS); secondary endpoints were event-free survival (EFS) and functional outcomes. The trial was terminated due to lack of equivalence and low accrual after first interim analyses., Trial Registration: NCT00210236., Results: Of 625 patients, 297 no-Ax and 310 Ax patients were maintained for final per-protocol analyses. OS and EFS at five years were not equivalent (Ax vs. no-Ax: 98% vs. 94% and 96% vs. 90% respectively). Recurrence was higher for no-Ax, particularly in the first five years after surgery. Axillary nodes were positive for 14% Ax patients but only 2% no-Ax patients experienced axillary node recurrence. Functional impairments were greater after ALNC., Conclusion: Our results fail to demonstrate equivalence of outcomes when ALNC is omitted from post-menopausal early breast cancer patient treatment. However the low locoregional recurrence rates warrant further examination over a longer duration, in particular to consider whether these would impact on survival., (Copyright © 2011 Elsevier Ltd.

Background: After breast conservative treatment (BCT), young age is a predictive factor for recurrence in patients with Ductal Carcinoma In Situ (DCIS) of the breast. The purpose of this study was to evaluate predictive factors for recurrence and outcomes in these younger women (under 40 years) treated for pure DCIS., Methods: From 1974 to 2003, 207 cases were collected in 12 French Cancer Centers. Median age was 36.3 years and median follow-up 160 months. Seventy four (35.8%) underwent mastectomy, 67 (32.4%) lumpectomy alone and 66 (31.9%) lumpectomy plus radiotherapy., Results: 37 recurrences occurred (17.8%): 14 (38%) were in situ and 23 (62%) invasive. After BCT, the overall rate of recurrence was 27% (33% in the lumpectomy plus radiotherapy group vs. 21% in the lumpectomy alone group). Comedocarcinoma subtype (p = 0.004), histological size more than 10 mm (p = 0.011), necrosis (p = 0.022) and positive margin status (p = 0.019) were statistically significant predictive factors for recurrence. The actuarial 15-year rates of local recurrence were 29%, 42% and 37% in the lumpectomy alone, lumpectomy and whole breast radiotherapy and lumpectomy + whole breast radiotherapy with additional boost groups respectively. After recurrence, the 10-year overall survival rate was 67.2%., Conclusion: High recurrence rates (mainly invasive) after BCT in young women with DCIS are confirmed. BCT in this subgroup of patients is possible if clear and large margins are obtained, tumor size is under 11 mm and necrosis- and/or comedocarcinoma-free., (Copyright © 2010 Elsevier Ltd.

Background: To prospectively determine the feasibility of sentinel lymph node biopsy (SLNB) in preoperatively diagnosed multiple unilateral synchronous invasive breast cancers., Patients and Methods: The Interest of Axillary Sentinel Lymph Node Biopsy in Multiple Invasive Breast Cancer (IGASSU) study was a prospective multi-institutional study with initial breast surgery, SLNB, and systematic axillary lymph node dissection (ALND). Patients eligible for the IGASSU study had an operable invasive multiple synchronous tumor (MST), defined as two or more physically separate invasive tumors in the same or different quadrant., Results: From 1 March 2006 to 31 August 2007, 216 patients were prospectively included from 16 institutions. Of these patients, 211 were assessable. The SLNB-identified rate was 93.4% (197 of 211). The false-negative rate (FNR) was 13.6% (14 of 103) [95% confidence interval (CI) 7% to 20%], and the accuracy was 92.9% (183 of 197) (95% CI 89% to 96%). In a univariate analysis, tumor location (only external location versus other location) was the only clinicopathological factor influencing the FNR [22% (11%-33%) versus 7% (4%-10%)], even then median aggregate histological tumor size was smaller in external tumors [17 mm (range 12-80 mm) versus 34 mm (range 8-90 mm), P = 0.016]., Conclusion: With a FNR of 13.6%, we do not recommend SLNB as a routine procedure for MST, even for small tumor.

Purpose: Predictive factors of non-sentinel lymph node (NSN) involvement at axillary lymph node dissection (ALND) have been studied in the case of sentinel node (SN) involvement, with validation of a nomogram. This nomogram is not accurate for SN micrometastasis. The purpose of our study was to determine a nomogram for predicting the likelihood of NSN involvement in breast cancer patients with a SN micrometastasis., Methods: We collated 909 observations of SN micrometastases with additional ALND. Characteristics of the patients, tumours and SN were analysed., Results: Involvement of SN was diagnosed 490 times (53.9%) with standard staining (HES) and 419 times solely on immunohistochemical analysis (IHC) (46.1%). NSN invasion was observed in 114 patients (12.5%), whereas 62.3% (71) had only one NSN involved and 37.7% (43) two or more NSN involved. In multivariate analysis, significant predictive factors were: tumour size (pT stage < or = 10 mm or >11 and < or = 20 or >20 mm [odds ratio (OR) 2.1 and 3.43], micrometastases detected by HES or IHC [OR 1.64], presence or absence of lymphovascular invasion (LVI) [OR 1.76], tumour histological type mixed or not [OR 2.64]. The rate and probability of NSN involvement with the model are given for 24 groups, with a representation by a nomogram., Conclusion: One group, corresponding to 10.1% of the patients, was associated with a risk of NSN involvement of less than 5%, and five groups, corresponding to 29.8% of the patients, were associated with a risk < or = 10%. Omission of ALND could be proposed with minimal risk for a low probability of NSN involvement.

Ductal carcinoma in situ of the breast (DCIS) is rare in younger women, accounting for about 4% of all cases of DCIS in France, and tends to be diagnosed by clinical findings or casually, after plastic surgery. After breast conserving treatment, young age ( less than 40) is a predictive factor of relapses in patients with DCIS. Age may serve as one more parameter that should be considered in the complex decision-making process necessary to create a treatment plan for a woman with DCIS. Breast conservative treatment (BCT) could be used if: margins are free and more than 10 mm; if DCIS size is less than 11 mm and DCIS is free of necrosis and comedocarcinoma. Mastectomy ought to be proposed in case of: multifocal DCIS, or DCIS size more than 30 mm; invaded margins after re-excision; radiotherapy contraindicated; small breasts and patient choice. Immediate breast reconstruction should be proposed for patients with all the poor predictive factors. In other cases, treatment procedure will be explained to the patient and the treatment will be chosen by the patient in consultation with the medical team (radiologist, surgeon, pathologist and oncologist). Radiotherapy with boost or hormonotherapy with tamoxifen should not be used routinely but may be proposed individually.

Objectives: To analyze the characteristics and to establish prognosis factors for 52 men suffering from breast cancer from 1980 to 2004., Patients and Methods: Men treated for breast cancer (invasive or in situ). A retrospective study analyzed clinical and histological characteristics, and treatment procedures. The probability of survival or recurrence was calculated using the Kaplan-Meier method. Prognostic factors were studied using the Log Rank test., Results: The mean age of our patients was 63.5 years old. In 73.1% of cases, subaerolar tumors were the initial symptoms, the average size was 30.31 mm. Among patients, 17 (32.7%) had T1, 19 (36.5%) T2, two (3.8%) T3 and 14 (26.9%) T4. The most represented histological type was the infiltrative ductal carcinoma (84.6%). The spread rate to axillary lymph nodes was 63.6%. The hormone dependency of these tumors was proven in 84.6% of cases. Overall survival rate were about 69% at five years and 32% at 10 years. The spread to lymph node and to derm, the clinical stage were significant factors influencing disease free survival. None of these factors had any significance regarding overall survival., Discussion and Conclusion: Male breast cancer is a rare disease (about 1% of breast cancer) with a poor prognosis (32% 10 years disease free survival). An early diagnosis and better knowledge of the disease would certainly lead to improvement of prognosis.

Objectives: In a retrospective study of bilateral Ductal Carcinoma In Situ (DCIS), cases were analysed to determine the relationship between the two events., Material and Methods: From 1971 to 2001, among 812 patients with DCIS in Bergonie Institute, 78 suffering from bilateral DCIS and only19 were treated entirely in our institute. It was either synchronous DCIS or asynchronous (before 6 months). We realised a comparative study between, clinical and pathological characteristics of each DCIS., Results: In case of asynchronous DCIS, contra lateral DCIS occurred after a median 75-months period and until 22 years after the first event. We found at least for one histological subtype an agreement in 53% of cases. In 31% of cases, the grade was the same. For low plus intermediary grade versus high grade, the agreement was 53%. There was a subtype and grade agreement of 32% and a subtype or grade agreement in 63% of cases., Conclusion: Histological agreement between the two lesions indicated the possible existence of in situ bilateral disease in these women. The local relapse rate was 20% and all of them were invasive. The risk of relapse in controlateral breast is high and patient needs a long follow up even in case of mastectomy.

Objective: To determine the reliability of pretherapeutic laparoscopic pelvic lymphadenectomy in cervical cancer as a function of lymph node recurrences according to initial lymph node status: 1) to establish the false negative rate by analyzing lymph node recurrence in patients N-, 2) to verify treatment adequacy in patients N+ by comparing the rate of node recurrence to initial node positivity., Patients and Methods: Retrospective analysis of a prospectively registered patient database. One hundred and ninety patients treated by a combination of radiotherapy and surgery for cervical cancer stages 1b to 2b in 95% of cases had undergone, from March 1992 to June 2003, a previous laparoscopic pelvic lymphadenectomy. Median follow-up was 40 months (range: 3-126 months)., Results: Initial lymph node positivity (N+) was found in 79 patients (42%). Fourteen patients (7.4%) presented with lymph node recurrence, all of whom have died from disease. Lymph node recurrence was found in 4/111 patients N- (3.6%) and in 10/79 patients N+ (12.7%), of whom 8/10 occurred outside the radiation fields., Conclusion: With a very low false negative rate, accuracy of the laparoscopic pelvic lymphadenectomy in the determination of lymphatic spread in cervical cancer is confirmed. It can still be considered the gold standard despite recent developments (e.g. sentinel lymph node determination) to which they should be compared. Treatment adequacy in patients N+ is confirmed.

Aim: We report on the design, validation and evaluation of a DVD for patient information in a department of surgical oncology., Patients and Method: DVDs provided the patient with information about the anatomy, surgical techniques and post-operative complications on digestive cancers, oral cavity and breast tumours. After surgery a questionnaire was sent to the patients in order to evaluate their level of satisfaction and opinion regarding the pre-operative information they had been given., Results: One hundred and eight patients were invited to watch the DVD. Seventy-one percent of the patients considered that viewing the DVD had been positive and encouraging and 83% of all the patients would recommend its use. Among the 14 patients who experienced complications, only 21% declared having been well informed by the DVD and only 12% considered they were better prepared to face those complications., Conclusions: DVD based information systems are valuable and acceptable to patients, but the presentation of complications needs to be improved.

The " Standards, Options and Recommendations " (SOR) project, started in 1993, is a collaboration between the Federation of French Cancer Centres (FNCLCC), the 20 French cancer centres, and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. Objectives : To update the Standards, Options and Recommendations clinical practice guidelines for the management of ductal carcinoma in situ of the breast (DCIS). Methods : The working group identified the questions requiring up-dating from the previous guideline. Medline(r) and Embase(r) were searched using specific search strategies from year 1996 to year 2003. In addition several Internet sites were searched in October 2002. Results : Clinical guidelines have been defined for the management of diagnosis, treatment, follow-up, and treatment of recurrence of DCIS. The issue of hormone replacement therapy has also been addressed in the context of DCIS.

Objective: To assess the risk of local recurrence of intraductal carcinoma of the breast with a large series and a review of literature., Methods: We present a retrospective study of 331 cases treated for intraductal carcinoma of the breast. Only patients with at least 5 years follow-up were selected. We were specially interested in recurrence risk factors. In these patients with a long follow-up; pathology was reevaluated with new investigation technique., Results: After a median follow-up of 109 months, 40 local recurrences were observed; these lesions were invasive in 23 cases. Only one patient had recurrence after mastectomy. For the others, they had lumpectomy associated with radiotherapy in 12 cases. Histologic features, grade and therapeutic options were evaluated as risk factors of local recurrence., Conclusion: Follow-up after lumpectomy for intraductal carcinoma was studied. The status of tumor margins was important; irradiation appeared useful, specially in case of high grade carcinoma but further large prospective randomized studies are needed. The use of prognostic index is interesting, but there are still unanswered questions.

Liposarcoma of the breast is an unfrequent tumor that can be found in 45-55-year-old women, usually with benign clinical and radiological characteristics. We report the case of a 50-year-old patient treated with menopausal hormonal replacement therapy, for whom mammographic screening revealed a solid tumor. Lumpectomy was performed and histology reported liposarcoma of the breast. Two years after surgery alone no relapse was observed. Our case report underlines the possibility of discovering this type of tumor by means of mammographic examination performed during menopausal hormonal replacement therapy. It suggests good prognosis after surgery alone.
