The authors studied retrospectively 16 cases of malignant epithelial nasopharyngeal tumors which were treated at the Head and Neck Service of the Heliópolis Hospital, São Paulo, Brasil, from December 1977 to December 1983. The treatment was intra-arterial chemotherapy (IAC) followed by radiotherapy. The chemotherapeutic schedules were: methotrexate and vincristine, methotrexate, bleomycin and vincristine (2 different schedules) and methotrexate, bleomycin, vincristine and cisplatinum. Objective responses to IAC were observed in 18.6% of the cases. Only 3 patients are alive at 26, 37 and 53 months; 2 of them had exhibited response to IAC. The authors analyze the results and suggest randomized trials in order to determine the exact effects of this method of treatment.
