Overview
Brief Summary
The purpose of this study is to evaluate the efficacy and safety of first-line chemotherapy with cisplatin and irinotecan in advanced gastric cancer, and try to find out the optimal dosage of combination chemotherapy.
Detailed Description
Open label single arm phase II study of cisplatin and irinotecan in patients with advanced gastric carcinoma not previously treated with palliative chemotherapy. 40 Patients will be enrolled in this local trial. The primary objective of this study is to determine the response rate of the treatment.Schedule for this study is as follows: 8 cycles/14 days of irinotecan 125 mg/m2 on Day 1 and cisplatin 50 mg/m2 on Day2. This study will also include genotype investigations of UGT1A1 and ERCC1 expression in order to assess determinants of efficacy and toxicity of the treatment with cisplatin and irinotecan in the study population.
