Phase II Study of Oral S-1 Plus Irinotecan (IRIS) in Patients With Advanced Colorectal Cancer
Keywords
Abstract
Description
A multicenter Open-label, single-arm, phase II clinical trial is conducted on patients with histological stage IV colorectal cancer given irinotecan plus S-1. The usefulness of this regimens as 1st line therapy for colorectal cancer was evaluated by the disease-free survival rate (DFR), overall survival rate (OS), incidence and severity of adverse event.
