Abstract
A prospective study was carried out to investigate the effectiveness and toxicity of three courses of combination high-dose bolus CDDP and 120-hour continuous infusion 5-FU every three weeks prior to definitive surgery and/or radiation therapy in 35 patients with locally advanced Stage III and IV squamous cell carcinoma of the head and neck. Twenty-two patients (63%) achieved a CR and 11 (31%) a PR after three cycles of chemotherapy, for an objective response rate of 94%. Toxicity was clinically acceptable. Nausea and vomiting occurred in 23 of 35 (66%) without any patients discontinuing therapy for this reason. Leukopenia in 13 (37%) and reversible azotemia in six (17%). Following three courses of chemotherapy, 13 patients had surgical resection and 12 patients had radiation therapy. Ten of these 35 patients had no pathologic evidence of cancer in the surgical specimen or preradiation therapy biopsy. Only two patients of those achieving a complete objective response have relapsed. However, the median follow-up has been short. The authors concluded that three courses of CDDP and 5-FU is a highly effective and safe adjuvant treatment in patients with advanced carcinoma of the head and neck.
