Phase I/II study of cisplatin, 5-fluorouracil and alpha-interferon for recurrent carcinoma of the head and neck.
Current chemotherapy regimens have failed to demonstrate a significant impact on the overall survival of patients with recurrent head and neck cancer; therefore, new agents or combinations of agents are necessary to improve outcome. Alpha-interferon potentiates the activity in vitro of both agents of one of the most active regimens currently available, cisplatin and 5-fluorouracil. The purpose of the current study was to evaluate the feasibility and efficacy in patients with recurrent head and neck cancer of adding alpha-interferon to cisplatin 14 mg/m2 daily and 5-fluorouracil 700 mg/m2 daily for 5 days. No significant toxicity occurred with alpha-interferon at dose level 0, 1 x 10(6) units/m2 daily for five days. Of four patients treated at dose level +1, alpha-interferon 3 x 10(6) units/m2, two developed prolonged grade III neutropenic following the fourth course. One of three patients developed grade IV thrombocytopenia and 6 of 13 courses at this dose level resulted in grade III neutropenia. A phase II study was performed in 19 patients with cisplatin 17 mg/m2/day, 5-fluoruracil 700 mg/m2/day and alpha-interferon 3 x 10(6) units/m2/day. During the phase II study grade III neutropenia occurred in 6 patients and grade IV neutropenia in another patient during at least one course. Grade III and IV thrombocytopenia occurred in one patient each during the phase II study. Overall, major responses occurred in 7 or 23 patients (30%): 5 in phase I and 2 in phase II. In conclusion, the addition of alpha-interferon to cisplatin and 5-fluorouracil is feasible, but does not appear to increase response rates in recurrent head and neck cancer.
