Clinical Trial Summary

The purpose of this retrospective study is to evaluate the efficacy and the safety of trastuzumab + chemotherapies with or without taxanes among HER2-positive advanced gastroesophageal adenocarcinoma patients.

Description:

Studies have reported a beneficial role of trastuzumab combined to platin-5-FU based chemotherapy in first-line advanced HER2 positive gastroesophageal adenocarcinoma. However, the effect of taxanes combined with platin-5FU + trastuzumab (TPFT) is understudied.

In this context, the aim of this study is to evaluate the efficacy and the safety of trastuzumab + chemotherapies with or without taxanes among HER2-positive advanced gastroesophageal adenocarcinoma patients.
