    Les adĂ©nocarcinomes de l’intestin grĂȘle (AIG) sont des tumeurs rares et de mauvais pronostic Ă  un stade avancĂ©. Les donnĂ©es publiĂ©es concernant l’efficacitĂ© de la chimiothĂ©rapie palliative sont peu nombreuses. Le but de notre Ă©tude Ă©tait d’évaluer l’efficacitĂ© et la tolĂ©rance de diffĂ©rents protocoles « modernes » de chimiothĂ©rapie et de comparer l’efficacitĂ© des chimiothĂ©rapies Ă  base de sels de platine dans le traitement de premiĂšre ligne des AIG avancĂ©s. Cette Ă©tude rĂ©trospective multicentrique a inclus 93 patients (sexe masculin : 53 % ; Ăąge mĂ©dian : 56 ans ; site primitif duodĂ©nal : 53 %) avec un AIG avancĂ© (mĂ©tastatique : 86 %) traitĂ©s par LV5FU2 (n = 10), FOLFOX (n = 48), FOLFIRI (n = 19) ou LV5FU2- cisplatine (n = 16). Le taux de toxicitĂ© grade 3-4 Ă©tait significativement plus frĂ©quent dans le groupe de patients traitĂ©s par LV5FU2-cisplatine (75 %) comparativement aux autres groupes de patients (p = 0,001). Les mĂ©dianes de survie sans progression (SSP) Ă©taient de 7,7 ; 6,9 ; 6,0 et 4,8 mois (p = 0,16) et les mĂ©dianes de survie globale (SG) Ă©taient de 13,5 ; 17,8 ; 10,6 et 9,3 mois (p = 0,25) pour les quatre groupes de patients traitĂ©s par LV5FU2, FOLFOX, FOLFIRI et LV5FU2-cisplatine, respectivement. En analyse multivariĂ©e, l’indice de performance OMS Ă  2 (p < 0,0001) ainsi que des taux Ă©levĂ©s d’ACE (p = 0,02) et de CA 19-9 (p = 0,03) avant traitement Ă©taient les seuls facteurs indĂ©pendants significativement associĂ©s Ă  un mauvais pronostic. Dans le sous-groupe de patients traitĂ©s par sels de platine, ceux qui ont reçu une chimiothĂ©rapie par FOLFOX avaient de meilleures SSP et SG que les patients traitĂ©s par LV5FU2-cisplatine. En analyse multivariĂ©e, le traitement par FOLFOX Ă©tait un facteur significatif et indĂ©pendant de survie prolongĂ©e en termes de SSP (p < 0,0001) et SG (p = 0,02). Ainsi, cette Ă©tude, la plus grande rapportĂ©e Ă  ce jour, suggĂšre d’une part que l’indice de performance OMS et les taux d’ACE et CA 19-9 avant traitement sont des facteurs pronostiques indĂ©pendants de survie et, d’autre part que la chimiothĂ©rapie par FOLFOX est le traitement de choix en premiĂšre ligne des AIG avancĂ©s

    Use of Proton Pump Inhibitors and Risk of Pancreatic Cancer: A Nationwide Case-Control Study Based on the French National Health Data System (SNDS)

    International audienceBackground: Only a few studies investigated the association between proton pump inhibitors (PPIs) use and pancreatic cancer, with inconsistent results. Moreover, these studies had a number of methodological limitations. Our objective was to assess this association in a nationwide case-control study.Methods: We used the French National Health Data System (SNDS), covering 99% of the French population since 2006. Incident cases of pancreatic cancer, identified between 2014 and 2018, were matched with up to 4 controls on year of birth, sex, frequency of hospitalization within 8 years prior to index date, and department of residence. Associations between PPIs and pancreatic cancer were estimated using conditional logistic regression models adjusted for sociodemographic characteristics, risk factors of pancreatic cancer (including diabetes mellitus, tobacco-related diseases, and morbid obesity), and other comorbidities.Results: 23,321 cases of pancreatic cancer (mean age 69.8 years, 51.7% males) and 75,937 matched controls were included. Overall, 77.8% of cases and 75.5% of controls were PPI ever users. Ever (vs. never) PPI use was associated with an increased risk of pancreatic cancer (adjusted OR [aOR]=1.05, 95% CI: 1.01-1.09). A dose-response relationship was observed (1-30 cumulative defined daily dose [cDDD]: aOR=0.92, 95%CI: 0.87-0.97; 31-180 cDDD: aOR=1.05, 95%CI: 1.00-1.11; 181-1080 cDDD: aOR=1.18, 95%CI: 1.12-1.24; >1080 cDDD: aOR=1.17, 95%CI: 1.10-1.23).Conclusions: Based on these findings, a slight increase in the risk of pancreatic cancer associated with high cumulative doses of PPIs cannot be excluded.Impact: Given the overuse of PPIs, efforts should be continued to limit treatments to appropriate indications and durations

    FOLFIRINEC: a randomized phase II trial of mFOLFIRINOX vs platinum-etoposide for metastatic neuroendocrine carcinoma of gastroenteropancreatic or unknown origin

    International audienceBackgroundPoorly differentiated neuroendocrine carcinomas (NEC) are rare diseases with a poor prognosis. Platinum-etoposide (PE) has been the recommended first-line treatment for decades. FOLFIRINEC (NCT04325425) is a national multicenter randomized phase II study which aims to challenge this standard regimen.MethodsThe primary objective is to compare the median progression-free survival (PFS) under mFOLFIRINOX versus PE. The secondary objectives are to evaluate the objective response rates (ORR), median overall survival (OS), safety and quality of life. The associated real-time translational study will establish a molecular profile for each patient enrolled.Main inclusion criteria areNEC of gastroenteropancreatic (GEP) or unknown origin, metastatic and RECIST 1.1 evaluable disease, tumor sample available and no contraindication to chemotherapy. Patients will be randomized 1:1 between PE every 21 days for 6–8 cycles and mFOLFIRINOX every 14 days for up to 12 cycles and stratified according to center, performance status, Ki67 and pathological subtype.This trial will randomize 218 patients (24 months of follow-up) to have 80% power to detect an improvement of the median PFS from 5 months under PE to 7.5 months under mFOLFIRINOX (HR of 0.67, α =5%, two-sided). An intermediate analysis is planned at 50% of events
