Brief summary

Patients will be treated with irinotecan (150mg/m2) followed by oxaliplatin (85mg/m2)on day 1 and S-1(80mg/m2/day) from day 1 to 14 every 3 weeks. Patients will receive up to a planned treatment of maximum 12 cycles of chemotherapy. Response assessement will be performed every 2 cycles of chemotherapy.

Inclusion criteria

1. Histologically or cytologically confirmed gastric adenocarcinoma with recurrent or metastatic disease 2. Age ≥18 years 3. Eastern Cooperative Oncology Group (ECOG) performance status 0-2 4. Disease status must be that of measurable disease as defined by RECIST criteria:Measurable lesions: Lesions that can be accurately measured in at least one dimension by any of the following: - CT of abdomen, pelvis or thorax, if the longest diameter to be recorded is at least 10 mm with spiral CT- Chest x-ray, if the lung lesion to be recorded is clearly defined and surrounded by aerated lung and the diameter to be recorded is at least 20 mm- Physical examination, if the clinically detected lesions are superficial (e.g., skin nodule and palpable lymph nodes) and at least 10 mm 5. No prior treatment for recurrent or metastatic disease; prior adjuvant/neoadjuvant therapy is allowed if at least 12 months have elapsed between completion of adjuvant/neoadjuvant therapy and enrolment into the study. However, prior oxaliplatin and/or irinotecan as adjuvant therapy are not allowed. 6. Adequate major organ function including the following: Hematopoietic function: ANC ³ 1,500/mm3, Platelet ³ 100,000/mm3Hepatic function: serum bilirubin 1.5 mg/dl, AST/ALT levels 2.5 x UNL ( 5 x UNL if liver metastases are present)Renal function: serum creatinine UNL 7. Patients should sign a written informed consent before study entry

Exclusion criteria

Inadequate cardiovascular function:New York Heart Association class III or IV heart diseaseUnstable angina or myocardial infarction within the past 6 monthsHistory of significant ventricular arrhythmia requiring medication with antiarrhythmics or significant conduction system abnormality 3.
