Reste-t-il des indications de curage ganglionnaire dans les cancers épithéliaux de l’ovaire après l’essai LION ?

International audienceIn March 2019, Harter et al. published the results of the LION study (Lymphadenectomy in patients with advanced ovarian neoplasms) which raises the question of pelvic and para-aortic lymphadenectomy for patients with advanced-stage epithelial ovarian cancer (EOC). These results influenced the new French recommendations published in December 2018 by the French National Cancer Institute (INCa). Thus, it no longer seems consistent to perform a systematic lymphadenectomy for patients for whom there is no argument for nodal involvement, when a macroscopic complete peritoneal cytoreductive surgery has been performed. The question of preoperative lymph node assessment is therefore essential, whereas more than half of the patients in the LION study had metastatic lymph node involvement that was histologically proven. For the assessment of lymph node status by imaging, superior sensitivity for Positron Emission Tomography is demonstrated in comparison with CT-scan or Magnetic Resonance Imaging. Nevertheless, thoraco-abdomino-pelvic CT-scan with contrast injection remains the gold standard for this indication. In the absence of suspected involvement, supra-renal, mesenteric, coelio-hepatic, and cardio-phrenic lymphadenectomy are not recommended. Lymphadenectomies should always be performed in the other situations of EOC management apart from the rare case of stage 1 expansile subtype mucinous carcinoma. The aim of this review is to discuss lymphadenectomy indications for the surgical management of EOC by taking into account new data from the scientific literature

Impact of obesity on the results of fertility-sparing management for atypical hyperplasia and grade 1 endometrial cancer

International audienceObjectives The aim of the present study was to evaluate the impact of obesity on reproductive and oncologic outcomes on the success of fertility-sparing management. Methods This retrospective multicenter cohort study included women treated conservatively for atypical hyperplasia (AH) and endometrial cancer (EC) to preserve fertility. Five inclusion criteria were defined: (i) the presence of AH or grade 1 EC confirmed by two pathologists; (ii) adequate radiological examination before conservative management; (iii) available body mass index (BMI) at the beginning of treatment; and (iv) a minimum follow-up time of six months. Results Forty patients fulfilled the inclusion criteria (17 had EC, and 23 had AH), mean age and BMI were 33 years and 29 kg/m2 respectively. Among the 15 obese patients, after medical treatment, 10 patients responded (67%) and three relapsed, whereas in the 25 non-obese patients, 19 responded (76%) and three relapsed (p = 0.72). The overall pregnancy rate and follow-up time were 35% and 35 months respectively. Among the 15 obese patients, after medical treatment, two patients became pregnant, whereas in the 25 non-obese patients, 12 became pregnant (p = 0.04). Conclusion Despite similar response and recurrence rates, our results suggest that fertility-sparing management for AH and EC is associated with a lower probability of pregnancy in obese patients

Association between maternal social deprivation and prenatal care utilization: the PreCARE cohort study

International audienceAbstractBackgroundMaternal social deprivation is associated with an increased risk of adverse maternal and perinatal outcomes. Inadequate prenatal care utilization (PCU) is likely to be an important intermediate factor. The health care system in France provides essential health services to all pregnant women irrespective of their socioeconomic status. Our aim was to assess the association between maternal social deprivation and PCU.MethodsThe analysis was performed in the database of the multicenter prospective PreCARE cohort study. The population source consisted in all parturient women registered for delivery in 4 university hospital maternity units, Paris, France, from October 2010 to November 2011 (N = 10,419). This analysis selected women with singleton pregnancies that ended after 22 weeks of gestation (N = 9770). The associations between maternal deprivation (four variables first considered separately and then combined as a social deprivation index: social isolation, poor or insecure housing conditions, no work-related household income, and absence of standard health insurance) and inadequate PCU were tested through multivariate logistic regressions also adjusted for immigration characteristics and education level.ResultsAttendance at prenatal care was poor for 23.3% of the study population. Crude relative risks and confidence intervals for inadequate PCU were 1.6 [1.5–1.8], 2.3 [2.1–2.6], and 3.1 [2.8–3.4], for women with a deprivation index of 1, 2, and 3, respectively, compared to women with deprivation index of 0. Each of the four deprivation variables was significantly associated with an increased risk of inadequate PCU. Because of the interaction observed between inadequate PCU and mother’s country of birth, we stratified for the latter before the multivariate analysis. After adjustment for the potential confounders, this social gradient remained for women born in France and North Africa. The prevalence of inadequate PCU among women born in sub-Saharan Africa was 34.7%; the social gradient in this group was attenuated and no longer significant. Other factors independently associated with inadequate PCU were maternal age, recent immigration, and unplanned or unwanted pregnancy.ConclusionSocial deprivation is independently associated with an increased risk of inadequate PCU. Recognition of risk factors is an important step in identifying barriers to PCU and developing measures to overcome them

Consultation personnalisée d'évaluation du risque de cancer du sein: premiers résultats

International audienceIntroductionIn France, participation in the organized breast cancer screening program remains insufficient. A personalized approach adapted to the risk factors for breast cancer (RBC) should make screening more efficient. A RBC evaluation consultation would therefore make it possible to personalize this screening. Here we report our initial experience.Material and methodThis is a prospective study on women who were seen at the RBC evaluation consultation and analyzing: their profile, their risk assessed according to Tyrer Cuzick model (TC) ± Mammorisk© (MMR), the existence of an indication of oncogenetic consultation (Eisinger and Manchester score), their satisfaction and the recommended monitoring.ResultsAmong the women who had had a TCS and/or MMR evaluation of SCR (n = 153), 76 (50%) had a high risk (n = 67) or a very high risk (n = 9). Almost half (47%) had a possible (15%) or certain (32%) indication to an oncogenetic consultation. Regarding this consultation, 98% of women were satisfied or very satisfied. In total, 60% of women had a change in screening methods.ConclusionThis RBC evaluation consultation satisfies women and for a majority of them, modifies their methods of breast cancer screening.IntroductionL’adhésion en France au programme de dépistage organisé du cancer du sein demeure insuffisante. Une approche personnalisée adaptée aux facteurs de risque de cancer du sein (RCS) permettrait une meilleure efficience du dépistage. Une consultation d’évaluation du RCS permettrait donc de personnaliser ce dépistage. Nous rapportons ici notre expérience initiale.Matériel et méthodeIl s’agit d’une étude prospective portant sur les femmes ayant été vues à la consultation d’évaluation du RCS et analysant : leur profil, leur risque évalué selon les modèles de Tyrer Cuzick (TC) ± Mammorisk© (MMR), l’existence d’une indication de consultation d’oncogénétique (scores d’Eisinger et de Manchester), leur satisfaction et la surveillance préconisée.RésultatsParmi les femmes ayant eu une évaluation du RCS par le modèle TC et/ou MMR (n = 153), 76 (50 %) avaient un risque élevé (n = 67) ou très élevé (n = 9). Près de la moitié (47 %) avait une indication possible (15 %) ou certaine (32 %) à une consultation d’oncogénétique. Concernant cette consultation, 98 % des femmes étaient satisfaites ou très satisfaites. Au total, 60 % des femmes ont eu un changement des modalités de surveillance.ConclusionCette consultation d’évaluation du RCS satisfait les femmes et pour une majorité d’entre elles, modifie les modalités de leur surveillance mammaire

Residual Microscopic Peritoneal Metastases after Macroscopic Complete Cytoreductive Surgery for Advanced High-Grade Serous Ovarian Carcinoma: A Target for Folate Receptor Targeted Photodynamic Therapy?

International audienceDespite conventional treatment combining complete macroscopic cytoreductive surgery (CRS) and systemic chemotherapy, residual microscopic peritoneal metastases (mPM) may persist as the cause of peritoneal recurrence in 60% of patients. Therefore, there is a real need to specifically target these mPM to definitively eradicate any traces of the disease and improve patient survival. Therapeutic targeting method, such as photodynamic therapy, would be a promising method for such a purpose. Folate receptor alpha (FRα), as it is specifically overexpressed by cancer cells from various origins, including ovarian cancer cells, is a good target to address photosensitizing molecules. The aim of this study was to determine FRα expression by residual mPM after complete macroscopic CRS in patients with advanced high-grade serous ovarian cancer (HGSOC). A prospective study conducted between 1 June 2018 and 10 July 2019 in a single referent center accredited by the European Society of Gynecological Oncology for advanced EOC surgical management. Consecutive patients presenting with advanced HGSOC and eligible for complete macroscopic CRS were included. Up to 13 peritoneal biopsies were taken from macroscopically healthy peritoneum at the end of CRS and examined for the presence of mPM. In case of detection of mPM, a systematic search for RFα expression by immunohistochemistry was performed. Twenty-six patients were included and 26.9% presented mPM. In the subgroup of patients with mPM, FRα expression was positive on diagnostic biopsy before neoadjuvant chemotherapy for 67% of patients, on macroscopic peritoneal metastases for 86% of patients, and on mPM for 75% of patients. In the subgroup of patients with no mPM, FRα expression was found on diagnostic biopsy before neoadjuvant chemotherapy in 29% of patients and on macroscopic peritoneal metastases in 78% of patients. FRα is well expressed by patients with or without mPM after complete macroscopic CRS in patients with advanced HGSOC. In addition to conventional cytoreductive surgery, the use of a therapeutic targeting method, such as photodynamic therapy, by addressing photosensitizing molecules that specifically target FRα may be studied
