Phase II Clinical Study of Preoperative S-1/CPT-11 Combination Chemotherapy in Patients With Locally Advanced Gastric Cancer
Phase II Clinical Study of Preoperative S-1/CPT-11 Combination Chemotherapy in Patients With Locally Advanced Gastric Cancer
RATIONALE: Drugs used in chemotherapy, such as S-1 and irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Giving chemotherapy before surgery may shrink the tumor so that it can be completely removed.
PURPOSE: This phase II trial is studying how well giving S-1 together with irinotecan works in treating patients who are undergoing surgery for locally advanced stomach cancer.
OBJECTIVES:
Primary
Secondary
OUTLINE: This is a multicenter study.
Patients receive oral S-1 on days 1-21 and irinotecan IV over 90 minutes on days 1 and 15. Treatment repeats every 28 days for 2 courses in the absence of disease progression or unacceptable toxicity. Patients then undergo gastrectomy with lymphadenectomy. After surgery, patients resume treatment with S-1 alone as before for 1 year.
PROJECTED ACCRUAL: A total of 70 patients will be accrued for this study.
