5FOLFOXIRI vs FOLFIRINOX as first-line chemotherapy in patients with advanced pancreatic cancer: A population-based cohort study显示文摘BACKGROUND FOLFIRINOX regimen is the first-line reference chemotherapy(L1)in advanced pancreatic ductal adenocarcinoma(aPDAC).FOLFOXIRI,a schedule with a lower dose of irinotecan and no bolus 5-fluorouracil,has demonstrated efficacy and feasibility in colorectal cancer.AIM To investigate the potential clinical value of FOLFOXIRI in patients with aPDAC in routine clinical practice.METHODS Analyses were derived from all consecutive aPDAC patients treated in L1 between January 2011 and December 2017 in two French institutions,with either FOLFOXIRI(n=165)or FOLFIRINOX(n=124)regimens.FOLFOXIRI consisted of irinotecan(165 mg/m2),oxaliplatin(85 mg/m2),leucovorin(200 mg/m2)and 5-fluorouracil(3200 mg/m2 as a 48-h continuous infusion)every 2 wk.Ninety-six pairs of patients were selected through propensity score matching,and clinical outcomes of the two treatment regimens were compared.RESULTS Median overall survival was 11.1 mo in the FOLFOXIRI and 11.6 mo in the FOLFIRINOX cohorts,respectively.After propensity score matching,survival rates remained similar between the two regimens in terms of overall survival(hazard ratio=1.22;P=0.219)and progression-free survival(hazard ratio=1.27;P=0.120).The objective response rate was 37.1%in the FOLFOXIRI group vs 47.8%in the FOLFIRINOX group(P=0.187).Grade 3/4 toxicities occurred in 28.7%of patients in the FOLFOXIRI cohort vs 19.5%in the FOLFIRINOX cohort(P=0.079).FOLFOXIRI was associated with a higher incidence of grade 3/4 digestive adverse events.Hematopoietic growth factors were used after each chemotherapy cycle and the low hematological toxicity rates were below 5%with both regimens.CONCLUSION FOLFOXIRI is feasible in L1 in patients with aPDAC but does not confer any therapeutic benefit as compared with FOLFIRINOX.The low hematological toxicity rates strengthened the relevance of primary prophylaxis with hematopoietic growth factors.Angélique Vienot Hortense Chevalier Clément Bolognini Elisabeta Gherga Elodie Klajer Aurélia Meurisse Marine Jary Stefano Kim Christelle d’Engremont Thierry Nguyen Fabien Calcagno Hamadi Almotlak Francine Fein Meher Nasri Syrine Abdeljaoued Anthony Turpin Christophe Borg Dewi Vernerey 2020World Journal of Gastrointestinal Oncology2020,12,3:0
6Development of a standardized in vitro approach to evaluate microphysical,chemical,and toxicological properties of combustion-derived fine and ultrafine particles显示文摘Ultrafine particles represent a growing concern in the public health community but their precise role in many illnesses is still unknown. This lack of knowledge is related to the experimental difficulty in linking their biological effects to their multiple properties, which are important determinants of toxicity. Our aim is to propose an interdisciplinary approach to study fine(FP) and ultrafine(UFP) particles, generated in a controlled manner using a mini CAST(Combustion Aerosol Standard) soot generator used with two different operating conditions(CAST1 and CAST3). The chemical characterization was performed by an untargeted analysis using ultra-high resolution mass spectrometry. In conjunction with this approach, subsequent analysis by gas chromatography–mass spectrometry(GC–MS) was performed to identify polycyclic aromatic hydrocarbons(PAH). CAST1 enabled the generation of FP with a predominance of small PAH molecules, and CAST3 enabled the generation of UFP, which presented higher numbers of carbon atoms corresponding to larger PAH molecules. Healthy normal human bronchial epithelial(NHBE) cells differentiated at the air-liquid interface(ALI) were directly exposed to these freshly emitted FP and UFP. Expression of MUC5AC, FOXJ1, OCLN and ZOI as well as microscopic observation confirmed the ciliated pseudostratified epithelial phenotype. Study of the mass deposition efficiency revealed a difference between the two operating conditions, probably due to the morphological differences between the two categories of particles. We demonstrated that only NHBE cells exposed to CAST3 particles induced upregulation in the gene expression of IL-8 and NQO1. This approach offers new perspectives to study FP and UFP with stable and controlled properties.Ana Teresa Juarez-Facio Clement Castilla Cecile Corbiere Helene Lavanant Carlos Afonso Christophe Morin Nadine Merlet-Machour Laurence Chevalier Jean-Marie Vaugeois Jerome Yon Christelle Monteil 2022Journal of Environmental Sciences2022,34,3:0
