[Evaluation of low-dose FP therapy as adjuvant therapy for gastric cancer]

In the present study, we demonstrate the result of low-dose FP treatment as an adjuvant therapy for 30 patients of stage II or more progressive gastric cancer. 5-FU and CDDP were injected intravenously for 10 days from day 1 through day 5, and day 8 through 12 for 2 weeks at a dose of 250 mg/body and 10 mg/body, or for 14 days at a dose of 250 mg/m2/day and 5 mg/m2/day, respectively. Patients were excluded if they received less than 80% of the respective doses in a course of treatment by the protocol. This constituted a course of chemotherapy, which was repeated every 4 weeks. Grade 3 neutropenia was observed in one case. Other toxicities were anorexia, nausea, weight loss, diarrhea, general fatigue and elevation of serum creatinine, but they were not so severe. The two-year survival rate was 100% in cur A cases, 85% in cur B, and 0% in cur C. The median survival time of the cur C patients was 10 months. These results indicate that low-dose FP therapy is safe and recommendable for cur A and cur B patients. However, other treatment methods such as sequential chemotherapy are needed for cur C gastric cancer patients.
