Superior clinical response and survival rates with initial bolus of cisplatin and 120 hour infusion of 5-fluorouracil before definitive therapy for locally advanced head and neck cancer.

One hundred ninety-one patients were treated by one of three cisplatin-containing multidrug protocols. The initial 77 patients received two courses of cisplatin and vincristine plus bleomycin. The next 26 patients received two courses of 5-fluorouracil and cisplatin, and the final 88 patients were placed on a three course 5-fluorouracil and cisplatin protocol. Overall response rates were similar for each of the three protocols. The complete response rate, however, was much better (54 percent) for three course 5-fluorouracil and cisplatin versus cisplatin vincristine, and bleomycin (29 percent) and two course 5-fluorouracil and cisplatin (19 percent). Survival curves were also better for the three course 5-fluorouracil and cisplatin segment of this nonrandomized pilot study.
