Résumé : Until now advanced gastric cancer has been generally treated with the FAM chemotherapy protocol. Due to the relatively low response rates with this protocol we decided to start a randomized prospective phase II trial comparing the FAM with the FAMTX protocol. The primary aim of our trial was to compare the toxicity in both protocols. The FAMTX protocol has been demonstrated to be fully comparable with the toxicity of the FAM protocol. The trial has been extended to a phase III study. With respect to response rates and survival times it is too early for evaluation. © 1989, Humana Press Inc.. All rights reserved.
