Abstract

From March 1983 to December 1989, 208 patients with locally advanced squamous cell carcinoma of the head and neck were successively included into two trials randomizing induction chemotherapy versus no pre-irradiation treatment. The chemotherapy regimen of the first trial, which included 100 patients, consisted of two cycles of a combination of cisplatin, bleomycin, vindesine, mitomycin C; while that of the second trial, which included 108 patients, consisted of three cycles of a combination cisplatin, 5-fluorouracil (continuous infusion) and vindesine. Local treatment was the same in two trials: 'primary' radiotherapy in all patients. The response was then evaluated at 55 Gy; in the case of poor response, surgery was performed, otherwise radiotherapy was continued to full doses (possibly followed by salvage surgery). The tumor and lymph node responses to chemotherapy (complete and partial response) were higher in the second trial and in the first one: 70% versus 50% for primary lesions, 47% versus 25% for lymph nodes. The toxicity of the two chemotherapy regimens was minimal. In the two trials, an initial major response to chemotherapy predicted subsequent efficacy of irradiation in 80% of the patients. Complete response rate at the end of irradiation correlates with the previous response to the chemotherapy. With a median follow-up of 60 months with the first chemotherapy regimen and 30 months with the second, overall survival and disease-free interval did not significantly differ in the two groups of patients, with or without chemotherapy. The incidence of distant metastasis was significantly reduced (P < 0.03) in the chemotherapy arms. This negative trial encourages the design of new chemotherapy protocols according to new schemes of treatment. For advanced stages of head and neck cancers (T3, T4, N2, N3), we recently launched a pilot study combining platinum and irradiation, but according to a concomitant schedule.
