Combination chemotherapy with CDDP and 5-FU is one of the most effective regimens for head and neck cancer. Recent studies have focused on biochemical modulation in the combination of CDDP and 5-FU. We studied the difference in effectiveness and adverse effects between two CDDP administration schedules for CDDP-5-FU combination chemotherapy. For regimen A, CDDP was administered on 5 consecutive days from day 1 to day 5, with a daily dose of 16 mg/m2. For regimen B, CDDP was administered at 80 mg/m2 on day 1. 5-FU was administered at 600 mg/m2/day in a continuous drip infusion for 120 hours from day 1 to day 5 for regimens A and B. Twenty-seven patients with head and neck squamous cell carcinoma were included in this study, and received either regimen A or B. Thirteen patients were given regimen A and 14 regimen B. With regimen A, 3 patients showed CR and the response rate was 76.9%. With regimen B, 3 patients showed CR and the response rate was 64.3%. The rates of efficacy were not different between regimen A and B. In contrast, a difference was seen with organ toxicity. Regimen B was more toxic for renal function than regimen A, while regimen A showed greater toxicity to bone marrow function. Acute nausea and vomiting were observed more frequently with regimen B. The difference in organs and symptoms of adverse effects, according to the schedule of CDDP administration would seem to be important in the treatment of head and neck cancer patients. The schedule of CDDP administration should be adjusted depending on the renal and bone marrow functions of the patients. Because multiple infusion of CDDP proved to be efficacious, low-dose CDDP and 5-FU will have a role for patients with head and neck squamous cell carcinoma. We also introduce other reports on the efficacy of low-dose CDDP and 5-FU.
