|Official title||Phase II Study of Oral S-1 Plus Irinotecan in Patients With Advanced Colorectal Cancer: Hokkaido Gastrointestinal Cancer Study Group HGCSG0302|
|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.|
