Randomized comparison of two chemotherapy, radiotherapy schemes for stage III and IV unresectable squamous cell carcinoma of the head and neck.
Between August 1983 and December 1986, 116 previously untreated patients with squamous cell carcinoma of the head and neck were randomized to receive induction chemotherapy followed by radiotherapy given in conventional fractions (55 patients, arm A) or an alternating chemotherapy and radiotherapy (3 courses of 20 Gy, 10 daily fractions each; 61 patients, arm B). The same chemotherapy was used in both arms: 6 mg/m2 vinblastine sulfate, hour 0; 30 mg bleomycin, hour 6; 200 mg methotrexate, hours 24 to 26; 45 mg leucovorin, hour 48. Forty-five patients had stage III disease and 71 had stage IV disease. All patients were evaluated for survival, 112 for toxicity, and 105 for analyses of response and time from the start of treatment until progression of disease. At the end of the combined treatment, we observed an overall response rate of 52% in arm A and an overall response rate of 64.9% in arm B. The incidence of mucositis was more relevant in arm B compared to arm A (P less than .00004). The difference in complete response, progression-free survival, and survival was statistically significant, with an advantage for arm B (P less than .03, P less than .02, and P less than .03, respectively). The analysis at a median follow-up of 36 months (range = 19 to 59) demonstrates a higher effectiveness for the alternating program.
