Thirty-six patients with advanced squamous cell carcinoma of the head and neck (SCCHN) were treated with a regimen including cisplatinum (CP) 30 mg/m2 i.v., 5-fluorouracil (5-FU) 500 mg/m2 i.v. bolus, folinic acid (FA) 200 mg/m2 i.v. in a continuous one-hour infusion, and bleomycin (B) 15 mg i.m. on the first and second days and repeated every 28 days. Thirty-three patients (25 with recurrent disease and 8 untreated) are evaluable for objective response. Of these, 4 (12%) achieved CR and 15 (45%) PR. All of the untreated patients responded. The mean duration of response in the patients with recurrent or metastatic disease was 5.5 months (range 2-10+). Remission of symptoms, such as pain and dysphagia, was obtained in 58% and in 44%, respectively. Subjective remission occurred almost exclusively in objectively responsive patients. The major side effects were leukopenia (55%) and nausea/vomiting (58%). This regimen is active in the treatment of advanced SCCHN. The quality of life may be improved in responsive patients.
