Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To assess the usefulness of irinotecan plus S-1 therapy based on the antitumor effect and survival period. by performing a phase I/II study of this combination in patients with inoperable or with postoperative gastric cancer

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A multicenter Open-label, single-arm, phase I/II clinical trial is conducted on patients with histological stage IV gastric cancer given irinotecan plus S-1. The usefulness of this regimens as 1st line therapy for gastric cancer was evaluated by the disease-free survival rate (DFR), overall survival rate (OS), incidence and severity of adverse event.
