First-line chemotherapy with docetaxel, oxaliplatin, and timed-flat infusion 5Fluorouracil in metastatic gastro-esophageal adenocarcinomas: The experience with FD/FOx regimen.

178Background: Triplet chemotherapies, with fluoropyrimidines, platin derivates and Docetaxel, represent an option for first line treatment of metastatic Gastro-Esophageal Adenocarcinoma (mGEA). To increase tolerability and dose intensity (DI), we previously developed an alternative way of administration of 5Fluorouracil (5FU), with nocturnal “timed-flat infusion” (TFI) (from 10:00 PM to 10:00 AM), without 5FU bolus and Folinic Acid, in several combination-schedules in breast and colorectal cancers. Methods: We report a retrospective analysis of 27 mGEA patients (pts) treated with FD/FOx regimen, a schedule of weekly TFI/5FU for two nights at 1000 or 900 mg/m2/night, associated to alternating Docetaxel at 50 mg/m2 on days 1 and 15, and Oxaliplatin at 80 mg/m2 on days 8 and 22, cycles repeated every 4 weeks. Results: From June 2007 to July 2017, 17 pts (62.9%) were treated with standard FD/FOx and 10 pts (37.1%) with modified FD/FOx (defined by any projected dose reduction compared to standard) due to age,...
