- W1969366993 abstract "Combined therapeutic regimens integrating chemotherapy, radiation therapy, and surgery are reported to be effective in treating advanced squamous cell carcinomas of the head and neck. The current study evaluates 58 consecutive patients with advanced (T4, N3) head and neck cancers. Forty patients (multimodal group) were treated with 2 courses of chemotherapy (cisplatin 2 mg/kg; methotrexate 280-560 mg/m2 with leucovorin rescue; bleomycin 30 mu X 3) followed by radiation therapy and surgery. Eighteen patients (combined group) were treated with preoperative radiation therapy followed by surgery. In the multimodal group there were 27 (67.5%) partial responses and nine (22.5%) complete responses, for an overall response rate of 90%. Response rates by site of primary lesion were: oral cavity, 11 of 11; oropharynx, 13 of 17; hypopharynx, 5 of 5; and larynx 7 of 7. Distant metastases (skin, lung, bone, central nervous system [CNS]) appeared in 16 patients (40%) (P less than 0.05 versus combined) at a median time of 8.5 months after diagnosis, 15 in patients having a partial (11) or complete (4) response. Thirteen patients (33%) developed distant metastases within 1 year of diagnosis (P less than 0.05 versus combined). In 11 of these patients, the primary lesion and neck disease were resectable. Two thoracotomies were performed for solitary pulmonary metastases; one was resected for cure. Fifteen patients (38%) underwent curative resection; 11 (73%) were alive at 1 year, and ten (67%) were free of disease. Overall survival was 20 of 40 (50%) at 1 year. In the combined group, there were 14 partial responses (78%) and no complete responses. Early distant metastases appeared in two patients (12.5%), at 2 and 6 months after diagnosis. Seven patients (38%) underwent curative resection; six of seven (86%) were alive at 1 year, four of seven (57%) were disease-free. Six of 16 patients at risk (37.5%) survived 1 year. After combined therapy, six of ten patients (60%) with responses to therapy survived 1 year versus 12 of 20 responders (57%) without distant metastases in the multimodal group. It is concluded that multimodal therapy for advanced head and neck cancer results in a higher response rate than with conventional combined therapy. The incidence of early and postoperative distant metastases was increased after the multimodal regimen. At 1 year there were no differences in survival between the combined and multimodal groups for responders without early metastases. Further observation is needed to determine the net long-term effects of this regimen. A prospective randomized comparison of combined and multimodal therapy for advanced lesions is indicated." @default.
