A comparison of doublet versus triplet chemotherapy regimens for esophagogastric adenocarcinoma (EGC): Is more always better?

124Background: Recent data showed that a taxane-containing triplet regimen (FLOT) was superior to an anthracycline-containing regimen (ECX/ECF). However, there is no comparison between more costly and toxic triplet (T) regimens versus doublets (D) in the perioperative setting (periCT) of EGC. Methods: A retrospective analysis of patients (pts) with newly diagnosed EGC was carried out at AC Camargo Cancer Center from 2007 to 2015. Pts received either a D with a fluopyrimidine and platin or T with addition of epirubicin or docetaxel. Variables used in the Cox model were age, site, TNM, Lauren subtype and periCT (T versus D). The selection between T and D was at physician's choice. Endpoints were Relapse Free Survival (RFS) and Overall Survival (OS). Results: A total of 128 pts were included. Median age was 59.5y (56.5y for T and 67y for D, respectively). Male/female ratio was 82/46. Sixty-six received T (DCF 26 pts, EOX 28, ECX 8, 4 others) and 62 received D (FOLFOX 47 pts, CF 13, 2 others). Primary site: g...
