[Hysterectomy: Practices evolution between 2009 and 2019 in France]. / Hystérectomie : évolution des pratiques entre 2009 et 2019 en France.

OBJECTIVE: Hysterectomy is the most common procedure in women. We wanted to make an assessment of the hysterectomy in France in 2019. We also assessed the variations over time in the indications and the surgical approch for hysterectomy, this with regard to the various events that may have been at the origin of the modification practices. METHODS: We used the Medical Information Systems Program in Medicine, Surgery, Obstetrics and Dentistry to extract all acts relating to a hysterectomy regardless of its route of approach from 2009 to 2019. RESULTS: Hysterectomy is a frequent procedure which was performed in nearly 60,000 women in France in 2019. The most frequently used surgical approach is now laparoscopy, performed in 30% of hysterectomies, followed by laparotomic (29%), then vaginal approaches (26%) and coelio-vaginal (15%). Laparoscopic procedures are performed more often in public than private hospitals. Adnexectomy is associated with 41% of hysterectomies. A decrease in the number of hysterectomies was observed between 2008 and 2019, from approximately 72,000 in 2008 to approximately 60,000 in 2019. This decrease occurs during a period in which new therapies have emerged as well as new recommendations. CONCLUSION: The evolution of the number of hysterectomies is correlated with the development of therapeutic alternatives for pathologies for which a hysterectomy has traditionally been performed.

Fertility and prognosis of borderline ovarian tumor after conservative management: Results of the multicentric OPTIBOT study by the GINECO & TMRG group.

OBJECTIVES: Description of fertility and prognosis of patients with borderline ovarian tumor (BOT) treated by fertility-sparing surgery through a longitudinal study from the French national cancer network. METHODS: All consecutive patients diagnosed with BOT from the French National Network dedicated to Ovarian Malignant Rare Tumors from 2010 and 2017 were selected. In 2018, an update was made by sending a questionnaire regarding recurrence and fertility to patients aged under 43 years at diagnosis and treated conservatively. We compared the characteristics of the patients with/without recurrence and with/without live birth. RESULTS: Fifty-two patients aged 18 to 42 years presented a desire of pregnancy. Thirty patients (58%) presented a FIGO IA tumor, and 20 patients were treated by bilateral cystectomies (38%). We observed at least one live birth for 33 patients (63%) and local recurrences in 20 patients (38%). Both recurrence and live birth in 17 patients (33%) were reported, with recurrence occurring before pregnancy, after a second fertility-sparing treatment, in half of the cases. No factors associated with recurrence or live birth in this study were identified. Moreover, in this population, both recurrence and live birth were independent of age, with a linear risk along time. Disease-free survival was worse for patients treated with bilateral cystectomy (n = 20, 38%), with no difference in terms of fertility. CONCLUSION: Two third of the patients experienced life birth after conservation surgery. We did not highlight an age/time from surgery for which the risk of recurrence outweighs the chance of pregnancy and to radicalize surgery. Moreover, almost a quarter of the live birth occurred after recurrence, with no more further event to date in these patients. The results encourage to consider a second fertility-sparing surgery after local borderline recurrence in the case of pregnancy desire. All these decisions must be discussed in specialized multidisciplinary boards.

CCL2/CCL5 secreted by the stroma induce IL-6/PYK2 dependent chemoresistance in ovarian cancer.

BACKGROUND: Minimal residual disease is the main issue of advanced ovarian cancer treatment. According to the literature and previous results, we hypothesized that Mesenchymal Stromal Cells (MSC) could support this minimal residual disease by protecting ovarian cancer cells (OCC) from chemotherapy. In vitro study confirmed that MSC could induce OCC chemoresistance without contact using transwell setting. Further experiments showed that this induced chemoresistance was dependent on IL-6 OCC stimulation. METHODS: We combined meticulous in vitro profiling and tumor xenograft models to study the role of IL-6 in MSC/OCC intereactions. RESULTS: We demonstrated that Tocilizumab® (anti-IL-6R therapy) in association with chemotherapy significantly reduced the peritoneal carcinosis index (PCI) than chemotherapy alone in mice xenografted with OCCs+MSCs. Further experiments showed that CCL2 and CCL5 are released by MSC in transwell co-culture and induce OCCs IL-6 secretion and chemoresistance. Finally, we found that IL-6 induced chemoresistance was dependent on PYK2 phosphorylation. CONCLUSIONS: These findings highlight the potential key role of the stroma in protecting minimal residual disease from chemotherapy, thus favoring recurrences. Future clinical trials targeting stroma could use anti-IL-6 therapy in association with chemotherapy.

[External multicentric validation of two scores predicting the risk of relapse in patients with borderline ovarian tumors: The nomogram of Bendifallah and the score of Ouldamer]. / Validation externe de 2 scores prédictifs de récidive de tumeurs mucineuses et séreuses borderline de l'ovaire : le nomogramme de Bendifallah et le score d'Ouldamer.

BACKGROUND: Borderline ovarian tumors are rare and can occur in young women. For these patients, a fertility sparing surgery should be discussed. Two predicting borderline ovarian tumor relapse risk models were developed in 2014 (Nomogram of Bendifallah) and 2017 (Score of Ouldamer). This study aimed to valid in an external population, these two scores using a multi-institutional BOT database. METHODS: In this bicentric and retrospective study, all consecutive patients comprising the variable nomogram documented treated between January 2006 and December 2012 for BOT in centre hospitalier de Poissy-Saint-Germain and hôpital René-Huguenin were included. A ROC model was established for each predicting scores. RESULTS: Sixty-five patients were included in the study. Twelve patients showed a recurrence (19%), three of them experienced an infiltrative cancer (5%). The median time of recurrence was 25 months (range: 8-115). The concordance index for the Nomogram of Bendifallah and the Score of Ouldamer were 0.88 (IC 95% [0.78-0.98]) and 0.87 (IC 95% [0.77-0.96]) respectively. CONCLUSION: This study from an independent population valids the Bendifallah nomogram and Ouldamer score for clinical use in predicting borderline ovarian recurrence.

Impact of bariatric surgery on fetal growth restriction: experience of a perinatal and bariatric surgery center.

BACKGROUND: Bariatric surgery is known to improve some pregnancy outcomes, but there is concern that it may increase the risk of small for gestational age. OBJECTIVE: To assess the impact of bariatric surgery on pregnancy outcomes and specifically of the type of bariatric surgery on the risk of fetal growth restriction. STUDY DESIGN: A single-center retrospective case-control study. The study group comprised all deliveries in women who had undergone bariatric surgery. To investigate the effects of weight loss on pregnancy outcomes, we compared the study group with a control group matched for presurgery body mass index. Secondly, to assess the specific impact of the type of surgery on the incidence of fetal growth restriction in utero, we distinguished subgroups with restrictive and malabsorptive bariatric surgery, and compared outcomes for each of these subgroups with a second control group, matched for prepregnancy body mass index. RESULTS: Among 139 patients operated, 58 had a malabsorptive procedure (gastric bypass) and 81 a purely restrictive procedure (72 a gastric banding and 9 a sleeve gastrectomy). Compared with controls matched for presurgery body mass index, the study group had a decreased rate of gestational diabetes (12% vs 23%, P = .02) and large for gestational age >90th percentile (11% vs 22%, P = .01) but an increased rate of small for gestational age <10th percentile. The incidence of small for gestational age was higher after gastric bypass (29%) than it was after restrictive surgery (9%) or in controls matched for prepregnancy body mass index (6%) (P < .01 between bypass and controls). In multivariable analysis, after adjustment for other risk factors, gastric bypass remained strongly associated with small for gestational age (adjusted odds ratio, 7.16; 95% confidence interval, 2.74-18.72). CONCLUSION: Malabsorptive bariatric surgery was associated with an increased risk of fetal growth restriction.
