A randomized trial of combined multidrug chemotherapy and radiotherapy in advanced squamous cell carcinoma of the head and neck. An interim report from the SECOG participants. South-East Co-operative Oncology Group.

This report concerns the design and results of a randomized prospective trial (SECOG 1) in the treatment of advanced Stage III and IV head and neck cancer with radical radiotherapy combined with polychemotherapy. Synchronous administration of chemotherapy and radiotherapy was compared with sequential chemotherapy and radiotherapy and VBM (vincristine, bleomycin and methotrexate) compared with VBM plus 5-fluorouracil in a 2 X 2 standard factorial design. Two-hundred-and-seventy patients were entered and 267 were included in the analysis. Treatment did not present serious problems of toxicity. The addition of 5-fluorouracil to VBM produced a significant improvement in disease-free survival (P = 0.04) though not in overall survival. Synchronous chemotherapy was similarly better than sequential chemotherapy, though not significantly so (P = 0.1). A new study (SECOG II), based on this was started in February 1984, and one-third of the patients are now being allocated to treatment by radiotherapy as the sole method of treatment.
