The French national network dedicated to rare gynecological cancers diagnosis and management could improve the quality of surgery in daily practice of granulosa cell tumors. A TMRG and GINECO group Study.

OBJECTIVE: The French national rare gynecological tumor network has been established to improve the quality of care through offering expertise in double reading histological diagnosis, reviewing cases and guiding management of these tumors through specialized multidisciplinary tumor boards and online clinical guidelines (www.ovaire-rare.com). The aim of this study is to evaluate the impact of the development and implementation of this network by assessing the conformity of medical practice with the guidelines concerning the granulosa cell tumors (GCTs). METHODS: This is a French nationwide study, including 463 patients (out of the 639 identified patients) with a definitive diagnosis of GCT between 2011 and 2016. Surgical practices were analyzed for conformity with the current guidelines (www.ovaire-rare.org). Medical records, surgical and pathological reports were systematically analyzed. Total conformity was defined by a conservative (unilateral salpingo-oophorectomy) or radical surgery (hysterectomy and bilateral salpingo-oophorectomy) including surgical staging (omentectomy, peritoneal biopsies and peritoneal cytology) according to the FIGO stage. Partial conformity referred to a conservative or radical surgery without surgical staging and non-conformity was defined as a non-optimal surgery as recommended by the guidelines. RESULTS: Median age at diagnosis was 49 years old (range 10-89). The median size of tumor was 94 mm (range 5-400). Radical surgery was performed in 240 patients (52%); while a fertility-sparing surgery was performed in 98 cases (21%). A surgical staging was performed in 76 cases (16%) and an evaluation of the endometrium in 289 cases (62%). Surgery was fully compliant with the guidelines in 65 patients (14%), partially compliant in 213 patients (46%), non-compliant in 137 patients (30%) and not assessable in 48 cases (10%). A statistically significant difference for compliance was observed in restaging surgery (p < 0,001), radical surgery (p = 0,017) and the period (before or after) of the implementation of the network (p < 0,001). Survival analyses did not allow us to demonstrate a significant difference in overall survival nor in PFS although there was a trend in favor of optimal surgery compared to incomplete/non optimal surgery. CONCLUSION: Surgical management's conformity to the guidelines increases over time from 2011 to 2016. According to this study, the implementation of a national network dedicated to rare gynecologic tumors seems to significantly improve the surgical management of the patients with ovarian granulosa cell tumors.

Genomic alterations and radioresistance in breast cancer: an analysis of the ProfiLER protocol.

BACKGROUND: Breast cancer (BC) patients with comparable prognostic features have heterogeneous outcomes, party related to a possible radiotherapy resistance leading to local-regional recurrences (LRR). The objective of the present study was to identify predictive molecular biomarkers of LRR of BC. PATIENTS AND METHODS: Genetic profile of 146 BC patients' tumours included in the ProfiLER clinical trial (NC01774409) between 2013 and 2016 were analysed using next-generation-sequencing and comparative-genomic-hybridization tests. Patients and tumour characteristics were retrospectively collected and analysed for association with genomic rearrangements (mutations, amplification, deletions). Only gene alterations observed in >3% of the tumours were selected. RESULTS: A total of 193 genomic rearrangements were identified, and 16 were observed in >3% of tumours. One was statistically correlated to the risk of local relapse. A median loco-regional progression-free survival (LRPFS) of 23.6 years was reported for PIK3CA mutation carriers (n = 31, 21.2%) versus 9.9 years for PIK3CA wild-type patients (HR 0.27, 95% CI 0.12-0.65, P = 0.002 in univariate analysis). PIK3CA mutation was identified as an independent protective factor on LRR using multivariate analysis (HR 0.29, 95% CI 0.09-0.99, P = 0.047). All other mutations, amplifications or deletions were not found associated with LRPFS. CONCLUSION: PIK3CA mutation was associated with a lower risk of local relapse in this population of BCs. This is consistent with recent studies suggesting PIK3CA to be part of biological pathways impacting the radiosensitivity.

[Axillary lymph node dissection after breast reconstruction by pedicled Latissimus dorsi: Operative steps and outcomes]. / Curage axillaire après reconstruction mammaire par lambeau de grand dorsal: principes chirurgicaux et résultats.

OBJECTIVES: We retrospectively reviewed all the cases of axillary lymph node dissection (ALND) performed within a year after an immediate breast reconstruction procedure by a pedicled Latissimus dorsi, which is transferred to the anterior thoracic wall through an axillary funnel. Operative technical steps are described taking account of the new anatomical relationship of the axilla. METHODS: We assessed postoperative immediate complications and late sequelaes. RESULTS: From 1999 to 2013, 21 ALND were performed. Immediate postoperative period was free of complication in 85% of cases when following the operative steps described in this work. Partial or total necrosis of the reconstructed breast did not occur. With a median follow-up of 64 months, 6 patients (28% of the whole population) presented at least one sequelae like a feeling of heavy arm (n=2, 9%) or a lymphedema (n=3, 14%), a chronic neuropathic pain (n=4, 19%) or a limitation in the arm range of motion (n=2, 9%). CONCLUSION: ALND after immediate breast reconstruction by a pedicled Latissimus dorsi is feasible and safe, without any additional postoperative complication in comparison with a classic ALND.

[Axillary lymph node metastases with an occult breast: About 16 cases from a cohort of 7770 patients]. / Envahissement ganglionnaire axillaire sans tumeur primitive mammaire retrouvée : à propos de 16cas issus d'une cohorte de 7770patientes.

OBJECTIVES: Isolated axillary lymph node metastases is an unusual clinical presentation of breast carcinoma. We studied its different issues. METHODS: This study is a follow-up study of 16patients, treated between 1996 and 2012, presenting with axillary metastases with an occult breast carcinoma, which could not be identified by physical examination nor by a conventional imaging or a breast MRI. Clinical characteristics, histological analysis, treatment, monitoring and five-year survival rate were studied. RESULTS: The incidence of this kind of breast cancer was 0.20%. A breast MRI was performed in 75% of the patients. The histology of these tumors showed a rate of hormono-sensibility of 50% and an HER2 overexpression of 44%. Sixty-nine percent of the patients had no breast surgery or radiotherapy; global five-year survival rate for these women was 77.4%±11.5. CONCLUSION: The survival rates of this study should lead the practitioner to choose a less aggressive breast therapy. Moreover, the histological characteristics explain the high metastatic potential of these tumors, and relate them to the HER2+ subclass of gene expression patterns of breast carcinomas.

[Postoperative morbidities after modified posterior pelvic exenteration for ovarian cancer]. / Complications après exentération pelvienne postérieure modifiée selon Hudson dans le cadre de tumeurs malignes ovariennes.

OBJECTIVE: Complication and survival analysis of cytoreduction surgery with modified posterior pelvic exenteration in the surgical treatment of the ovarian malignant tumor. METHODS: A retrospective monocentric study between 2000 and 2013 in Rhone-Alpes cancer treatment center. One hundred and fifty-two patients with ovarian cancer and treated by surgery with modified posterior pelvic exenteration were included. Complication in the 30 days after surgery was analysed by the Clavien-Dindo classification. RESULTS: In our study, rate of global complication was 62.5% with a morbidity rate of grave complication of 7.9%. Our rate of complete resection was 82.2%. Three fistulas (2.2%) were found. On average, there was 6.6±1.8 (2-11) surgery gesture associated with Hudson resection during surgery. In univariate analysis, there was a statistic significant association between complication from the rank II of Clavien-Dindo classification and supraradical surgery, post-chemotherapy surgery, recurrent surgery, the resection of a diaphragmatic dome, and the partial gastric resection. This association was also observed with the number of surgical gesture associated with Hudson resection. CONCLUSIONS: The main prognostic surgical factor in ovarian cancer is to obtain a no macroscopic residual disease. The modified posterior pelvic exenteration allowed to obtain it. Our study demonstrates a low rate of grave complication further to this type of surgery.

[Satisfaction in ambulatory patients with breast-conserving surgery and sentinel node biopsy for breast cancer]. / Satisfaction des patientes opérées par tumorectomie-ganglion sentinelle pour cancer du sein en ambulatoire.

OBJECTIVE: The objective of this study was to evaluate outpatient satisfaction for breast cancer surgery and compare with inpatient satisfaction. PATIENTS AND METHODS: Our observational prospective study included all patients who underwent breast cancer surgical procedure (breast-conserving surgery and sentinel node biopsy) between July and December 2013 in a cancer center. Patients were asked to answer a questionnaire at discharge and 30 days after surgery. RESULTS: One hundred and fifty-five patients (exclusively women) were included; the outpatient group comprised 102 patients and the inpatient group 53. The study showed no statistical difference in patients' satisfaction betweeen the two groups at discharge (P=0.20) and 30 days after surgery (P=0.30); 101 (99%) outpatients and 44 (95.7%) inpatients had very good or excellent level of satisfaction at discharge and 88 (92,7%) and 49 (98%), respectively 30 days after surgery. The overall mean satisfaction score was 9.1±1.2 [3-10] at discharge and 8.7±1.3 [3-10] 30 days after surgery. DISCUSSION AND CONCLUSION: Our study found high degree of satisfaction after breast surgery for cancer both for outpatients and inpatients. This suggests that ambulatory surgery is possible and valid for this type of oncologic breast surgery.

[Spontaneous regression of breast cancer after biopsy. About two cases]. / Régression spontanée de cancers mammaires après biopsie : à propos de deux cas.

We report two cases of spontaneous regression of breast cancer occurred in our institution. It was about a 34- and an 82-year-old patient. The examination revealed a palpable nodule. In both cases, biopsy revealed a negative immunohistochemical staining for estrogen and progesterone receptors, and HER-2 negative. Histological analysis of the surgical specimen found fibrous tissue rearrangement without carcinoma. In the first case, a sarcoidosis was diagnosed at the same time, the mediastinal nodes mimicked a metastatic cancer. These cases illustrate a rare phenomenon. The main hypothesis is a carcinoma- directed immune response triggered by the biopsy.
