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.

The oncogenic events involved in breast implant-associated anaplastic large cell lymphoma (BI-ALCL) remain elusive. To clarify this point, we have characterized the genomic landscape of 34 BI-ALCLs (15 tumor and 19 in situ subtypes) collected from 54 BI-ALCL patients diagnosed through the French Lymphopath network. Whole-exome sequencing (n = 22, with paired tumor/germline DNA) and/or targeted deep sequencing (n = 24) showed recurrent mutations of epigenetic modifiers in 74% of cases, involving notably KMT2C (26%), KMT2D (9%), CHD2 (15%), and CREBBP (15%). KMT2D and KMT2C mutations correlated with a loss of H3K4 mono- and trimethylation by immunohistochemistry. Twenty cases (59%) showed mutations in ≥1 member of the JAK/STAT pathway, including STAT3 (38%), JAK1 (18%), and STAT5B (3%), and in negative regulators, including SOCS3 (6%), SOCS1 (3%), and PTPN1 (3%). These mutations were more frequent in tumor-type samples than in situ samples (P = .038). All BI-ALCLs expressed pSTAT3, regardless of the mutational status of genes in the JAK/STAT pathway. Mutations in the EOMES gene (12%) involved in lymphocyte development, PI3K-AKT/mTOR (6%), and loss-of-function mutations in TP53 (12%) were also identified. Copy-number aberration (CNA) analysis identified recurrent alterations, including gains on chromosomes 2, 9p, 12p, and 21 and losses on 4q, 8p, 15, 16, and 20. Regions of CNA encompassed genes involved in the JAK/STAT pathway and epigenetic regulators. Our results show that the BI-ALCL genomic landscape is characterized by not only JAK/STAT activating mutations but also loss-of-function alterations of epigenetic modifiers., (© 2020 by The American Society of Hematology.)

Therapeutic innovations in the field of oncology allow to manage cancer as a chronic illness with treatments being administered over prolonged periods of time. In this context, it is now acknowledged that it is important to complete the assessment of benefit based on purely clinical endpoints using outcome measurement evaluated by patients themselves. The Patient reported outcome (PRO) concept has then emerged and there is an increasing interest in using the PROs as an indicator of the benefit of new therapeutic strategies. In this paper, we aim to illustrate the potential use and value of using PROs in the management of cancer patients. After a brief review of the PRO concept and it's link with the quality-of-life concept, this paper describes the actual implementation of PROs, first in clinical research, then in routine clinical practice. We then will focus on the difficulties in the French context to promote a larger use of PROs in the routine clinical practice. This paper will show how the PROs are a useful tool to improve the management of cancer patients., (Copyright © 2018 Société Française du Cancer. Published by Elsevier Masson SAS.

Aims: To compare survival outcomes after mastectomy (Mt) and lumpectomy plus interstitial brachytherapy (LpIB) in the treatment of breast cancer local recurrence (LR) occurring after conservative surgery., Methods: Medical records of patients treated for an isolated LR from January 1, 1981 to December 31, 2009 were reviewed. To overcome the bias due to the fact that treatment choice (Mt or LpIB) was based on prognostic factors with LpIB proposed preferentially to women with good prognosis, Mt and LpIB populations were matched and compared with regard to overall survival (OS) and metastasis free survival (MFS)., Results: Among 348 patients analyzed, 66.7% underwent Mt, 17.8% LpIB and 15.5% Lp alone. After a median follow-up of 73.3 months, 65 patients had died (42/232 Mt, 8/62 LpIB, 15/54 Lp). Before matching, OS and MFS at 5 years were significantly better in the LpIB compared to the Mt group, due to significantly more frequent poor prognostic factors in the latter (p = 0,07 and p = 0,09 respectively, log-rank significance limit of 10%). After matching, the benefits of LpIB disappeared since MFS and OS rates were not significantly different in both groups (p = 0.68 and 0.88 respectively). After LpIB, the second LR rate was 17% at 5 years and 30% at 10 years., Conclusion: A second conservative breast cancer treatment associating lumpectomy and interstitial brachytherapy is possible for selected patients with LR, without decrease in neither OS nor MFS compared to mastectomy., (Copyright © 2017 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Context: Even if neoadjuvant chemotherapy (NACT) and oncoplastic techniques have increased the breast conserving surgery rate, mastectomy is still a standard for multifocal or extensive breast cancers (BC). In the prospect of increasing breast reconstruction, an alternative therapeutic protocol was developed combining NACT with neoadjuvant radiation therapy (NART), followed by mastectomy with immediate breast reconstruction (IBR). The oncological safety of this therapeutic plan still needs further exploration. We assessed pathological complete response (pCR) as a surrogate endpoint for disease free survival., Methods: Between 2010 and 2016, 103 patients undergoing mastectomy after NACT and NART were recruited. After CT and RT were administrated, a completion mastectomy with IBR by latissimus dorsi flap was achieved 6 to 8 weeks later. pCR was defined by the absence of residual invasive disease in both nodes and breast. Histologic response was analyzed for each immunohistochemical subset., Results: pCR was obtained for 53.4% of the patients. This pCR rate was higher in hormonal receptor negative (HER2 and triple negative) patients when compared to luminal tumours (69.7% vs 45.7%, p=0.023)., Discussion: The pCR rate found in this study is higher than those published in studies analyzing NACT (12.5%-27.1%). This can be explained by the combination of anthracycline and taxane, the use of trastuzumab when HER2 was overexpressed but also by RT associated to NACT., Conclusion: Inverting the sequence protocol for BC, requiring both CT and RT, allows more IBR without diminishing pCR and should therefore be considered as an acceptable therapeutic option., (Copyright © 2016 Elsevier Ltd.

In patients with breast cancer, axillary lymph node micrometastasis detection has been more frequent with a better definition since the introduction of the sentinel node procedure. In this review, we focus on pN1mi micrometastasis and review the literature in order to determine factors involved in making the decision of a regional treatment., (Copyright © 2015 Société française de radiothérapie oncologique (SFRO).

Sentinel node biopsy without complementary axillary lymph node dissection was validated for T1-2 N0 unifocal breast cancer without previous treatment since several years. In the situation of multifocal multicentric breast tumors, this procedure was considered as a contraindication. The aim of this work was to analyse literature results to determine if sentinel lymph node biopsy can be considered as a valid option without complementary axillary lymph node dissection for negative sentinel lymph node., (Copyright © 2015 Elsevier Masson SAS.

Nipple-Sparing Mastectomy (NSM) is a procedure with skin-sparing mastectomy and nipple-areolar complex preservation in association with immediate reconstruction. The aim of this publication is to perform a review of oncological results, technical procedure, complications and indications of NSM with discussion of post-mastectomy radiotherapy indication. Local areolar recurrence is rare and treatment is performed by resection of the nipple-areolar complex. The nipple-areolar complex necrosis rate is a specific complication, observed between 1 to 30% in literature studies. Incisions and surgical procedure of dissection are discussed., (Copyright © 2014.

A therapeutic surgical de-escalation has been observed since many years with an actual prolongation for axillary lymph node area treatment. Axillary lymph node dissection (ALND) omission has been studied before and after validation of sentinel node (SN) biopsy procedure. A non-inferiority of ALND omission has been reported in case of non-involved SN. ALND omission has been studied in case of SN involvement without consensus in relation with scientific level of proof and with selective indications. The purpose of this work is to make a synthesis of the experiences on this subject then to envisage the current and future perspectives.

Objective: The management of recurrent ovarian cancer is based on intravenous chemotherapy with or without debulking surgery. The hyperthermic intraperitoneal chemotherapy (HIPEC) is sometimes proposed as a complement to complete surgery. The purpose of this study was to evaluate the feasibility, morbidity and survival of HIPEC associated with complete surgical cytoreduction in the management of patients with a first recurrence of ovarian cancer., Patients and Methods: Between 2005 and 2010, 27 patients underwent surgery for a recurrence of ovarian cancer. Among them, 17 patients (63%) have received HIPEC., Results: Sixteen patients (94%) were completely resected after surgery. No patient died postoperatively. Two patients had intraoperative complications: a bladder injury and a section of the ureter. Eight patients had postoperative complications including 3 grade 3 or higher (two organ failure and one reoperation). Fifteen patients had a recurrence with a median DFS of 11.9 months (95% CI [5.4-32.9]) from the HIPEC. The median overall survival from diagnosis was 107.8 months., Discussion and Conclusion: These results showed that the association of HIPEC with a complete cytoreduction for recurrent ovarian cancer presents acceptable morbidity and survival. The results of the ongoing French multicenter study (CHIPOR) are expected to generalize this support., (Copyright © 2013 Elsevier Masson SAS. All rights reserved.)

Micrometastases or sub-micrometastases can be detected by standard histopathological method sometimes associated with immunohistochemistry in lymph nodes, bone marrow and blood. The consequence of these small size involvement may be prognostic and therapeutic. Two factors are necessary to assess this kind of involvement: the rate of involvement of non-sentinel lymph node after axillary lymph node dissection and significative difference of survivals. The rate of involvement of non-sentinel lymph node in case of micrometastases or sub-micrometastases is different from the rate of involvement in case of no lymph node metastases (7 to 8%) or in case of macrometases (30 to 50%). Micrometastase is an important factor to determine the rate of involvement of non-sentinel lymph node, the overall or disease free survival and to assess the need of radiotherapy and chemotherapy. In conclusion, micrometastases and sub-micrometastases have a clinical impact even if complementary axillary lymph node dissection is still discussed.

Objectives: To describe our single-port experience in gynecologic oncology surgery, and emphasize the feasibility to use the single-port in this surgery., Patients and Methods: It is a retrospective, feasibility study, monocentric. All patients who were operated by the single-port, between 1st January 2010 to 1st November 2011, were included., Results: We note that 107 patients were included. We made different interventions: uni- and bilateral salpingo-ovariectomy, hysterectomy, pelvic and para-aortic lymph node sampling or lymphadenectomy in gynecologic malignancies. The median age of the population and the body mass index were respectively 52 and 22.6 kg/m(2). In total, six interventions will be converted. The median hospital stay of patients, all procedures combined, was 2 days. We find low rate of postoperative complications., Conclusion: Gynecological cancer surgery appears feasible for single-port. However, we need other studies to confirm a benefit of using the single-port compared to conventional laparoscopy., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

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.)

Objectives: The aim of this study is to establish the feasibility of the management of recurrent pelvic cancers by robot-assisted laparoscopy, and particularly the feasibility of robot-assisted laparoscopy anterior pelvic exenteration, from a single center series of seven patients., Patients and Methods: From February 2007 to April 2010, all patients cared for recurrent pelvic cancer have been included (n=7). Five patients have been cared for a cervical cancer recurrence, one patient for recurrent VAIN 3, and one patient for squamous cell carcinoma of the vaginal vault after hysterectomy for cervical carcinoma in situ. All patients were benefited from robot-assisted laparoscopy: two had surgery such as anterior pelvic exenteration with Miami Pouch urinary reconstruction, and five had colpectomy with or without lymph node removal, including one with vaginal preparation first before vaginal cuff resection. Data were collected prospectively identifying treatment history, intraoperative data, immediate outcomes, pathological findings, and long-term outcomes., Results: From February 2007 to April 2010, 195 patients underwent robot-assisted laparoscopy at the Institut Paoli-Calmettes. Among them, seven patients had pelvic cancer recurrence. The median age was 53 years (44 to 67). The median BMI was 25 (19.7 to 35.3). The median Karnofsky index was 100 (80-100). The median operative time was 210 min (90 to 300) for colpectomy, 480 min for pelvectomy, 240 min (90-480) for the serie. The mean duration of the installation of the robot, all procedures combined, is estimated at 22.5 min (±4.8 min). There was no conversion to laparotomy, the median blood loss was 340 ml (100 to 800). One patient was transfused with two red blood cells. There was a surgical complication (wound of the inferior mesenteric artery). There were no early postoperative complications and the median hospital stay was 6 days (3-24). There was a late postoperative complication: a patient who underwent anterior pelvic exenteration had impaired wound healing, with scarring requiring led by the VAC system. On pathological findings, the average number of nodes removed in the pelvic was 8.5 (±2) on the left, and 4 (±1.4) on the right. Three patients had involved margins; it was an anterior pelvic exenteration and two colpectomy. There was no hospital mortality, neither post-operative mortality at D30 and D90. After a median follow up of 22 months (9-34), the recurrence rate was 71% (5 patients out of 7), and one patient died 10 months after the intervention of a pulmonary embolism., Discussion and Conclusion: The surgical management of recurrent cervical cancer by laparoscopy-assisted robot is feasible for selected indications, and could be proposed as an alternative to laparotomy. Monitoring data in this series raise the question of the validity of conservative treatment in cases of recurrent pelvic cancer. The possibilities in terms of urinary and vaginal reconstruction remain to be defined. The impact of this surgical approach on oncological data must be confirmed., (Copyright © 2011 Elsevier Masson SAS. All rights reserved.)

The aim of this work is to specify surgical procedures for the breast and the axillary lymph node area after neoadjuvant chemotherapy. The extent of glandular resection was chosen using a rational based on the goals of neoadjuvant chemotherapy, the prognostical impact of response level and the evaluation of this response. The results of sentinel lymph node procedure before or after neoadjuvant chemotherapy are presented.

Objective: The aim of this study was to compare the feasibility and efficacy of robot-assisted laparoscopy with traditional laparotomy and conventional laparoscopy in a series of patients with locally advanced cervical cancer managed in our two institutions., Methods: Twenty-two patients who underwent robot-assisted laparoscopy were compared with 20 patients who underwent adjuvant surgery by laparotomy and 16 who underwent conventional laparoscopy, before the arrival of the Da Vinci surgical system., Results: There was no significant difference between the three groups in terms of body mass index, FIGO stage, or tumor histology. The complication rate was similar in the three groups of patients, although there was a trend towards more lymphatic complications in the robot-assisted subgroup managed medically. There was no significant difference in the recurrence rate between the robot-assisted laparoscopy, conventional laparoscopy and laparotomy groups (27.3%, 29.4% and 30%, respectively)., Conclusion: Robot-assisted laparoscopy is feasible after concurrent chemoradiation and brachytherapy in cases of locally advanced cervical cancer. This new surgical approach reduces hospital stay, and seems to result in less severe complications than conventional laparotomy without modifying the oncological outcome., (Copyright (c) 2009 Elsevier Ltd.

Background: Several authors reported sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NC). Nevertheless, the ideal time of SLNB is still a matter of debate., Methods: We evaluated the feasibility and the accuracy of SLNB before NC using a combined procedure (blue dye and radio-labelled detection) before NC. Axillary lymph node dissection (ALND) was performed after completion of NC in a homogeneous cohort study with clinically axillary node-negative breast cancer., Results: Among the 20 women who had metastatic SLNB (65%), 4 (20%) had additional metastatic node on ALND. By contrast, all the 11 women who had no metastatic SLNB had no involved nodes in the ALND. The SLN identification rate before NC was 100% with any false negative., Conclusions: SLNB before NC is a feasible and an accurate diagnostic tool to predict the pre-therapeutic axilla status. These findings suggest that ALND may be avoided in patients with a negative SLNB performed before NC.

Breast conserving surgery and mastectomy are equivalent for overall survival. However, the rate of local recurrence is higher for breast conserving surgery. Several predictive factors for local recurrence have been identified and some of them such as margins of resection, radiation therapy, chemotherapy, and hormonotherapy can be modified. The aim of this study is to review arguments in the literature to define optimal margins of resection. The orientation of the specimen and the inking of lateral margins are essentials for the histopathological analysis. Lateral margins are the most important since the resection is close to the pectoral muscle. According to the literature, the rate of local recurrence is higher when margins are positive. Moreover, the presence of tumoral cells on specimen after a re-excision is correlated with the positivity of the margins. There are no agreements about the number of millimeters requested to consider a margin sufficient. However, two millimeters seem to show a decrease of local recurrence. The influence of extensive intraductal component on local recurrence risk has been studied. Several factors are correlated and to define independent factors seem to be interesting.

Objective: This study was undertaken to evaluate prevalence of low urinary tract symptoms (LUTS) after Thierry's spatula delivery at first pregnancy., Patients and Methods: A retrospective study of 236 primiparous with instrumental delivery or spontaneous delivery who had delivered from January 2001 to December 2002. Low urinary tract symptoms (LUTS) were evaluated one year after delivery with a questionnaire. Incidence of LUTS was compared depending on mode of delivery., Results: Of the 236 patients included, 88.1% replied to the questionnaire, 106 who delivered spontaneously and 102 who underwent Thierry's spatula delivery. The incidence of urinary incontinence was similar after instrumental deliveries and after spontaneous vaginal deliveries (34.9 versus 24.5%, p=0.10). In univariate analysis, symptoms of urinary urgency and urinary frequency were higher after instrumental delivery than after spontaneous delivery, respectively, 34.9 versus 22.5%, p=0.049 and 19.8 versus 8.8%, p=0.03. After controlling for confounding factors, no difference in LUTS was observed between the two groups; the respective adjusted odds-ratios (95% IC) were 1,5 (0.8-3) for urinary incontinence, 1.7 (0.9-3.5) for urgency and 2.5 (0.9-6.3) for urinary frequency., Discussion and Conclusion: One year after delivery, one third of patients will present urinary incontinence and more than 50% will complain of bladder instability symptoms. Compared to spontaneous vaginal delivery, the use of Thierry's spatulas at first pregnancy does not induce higher risk of LUTS.

Background: A few studies report malnutrition in hospitalized patients., Material and Methods: This one-day cross-sectional survey performed in January 1999 assessed nutritional status and protein-energy intake in a pediatric population hospitalized in medicine or surgery units. Every child older than six months, hospitalized for more than 48 h and free of nutritional support (parenteral, enteral, or special regimens for metabolic diseases) was included., Results: Fifty-eight children among the 183 present the day of the study met the inclusion criteria and were included in the statistical analysis. They were hospitalized in medicine (48%), psychiatry (31%) and surgery (21%). The body mass index (BMI) was below -2 standard deviations (DS) in 21% of them. Excluding patients with anorexia nervosa, BMI was < -2 SD, > +2 SD, or in between these limits in respectively 12, 14 and 74%. Energy intake measured at the hospital was below 75% of the recommended dietary allowances in two-thirds of the children whether malnourished or not. Fifty percent of the malnourished children had been referred to a dietician the day of the study., Conclusions: Malnutrition is frequent in a population of hospitalized children. Energy intake and referral to a dietician are insufficient.
