Abstract
Twenty patients with previously untreated nasopharyngeal tumors received, as initial treatment, two courses of Schedule A chemotherapy including vincristine, 5-fluorouracil, bleomycin, hydrocortisone, methotrexate, and a folinic acid rescue, prior to definitive radiotherapy. Thirteen patients had Stage IV and seven had Stage III tumors, with nodal involvement in 18 patients (90%). Response to two courses of Schedule A chemotherapy was assessed on day 28, and overall, 18 patients responded. Side effects were minimal. Following radiotherapy 17 patients achieved a clinical complete remission. Durations of response ranged from 6 to 95+ months (median 40 months) and of survival from 8 to 95+ months (median 53 months). This chemotherapy protocol should be more widely evaluated as initial treatment in nasopharyngeal carcinomas since the 90% chemotherapy response rate and, after radiotherapy, 85% clinical complete remission rate was accomplished with minimal toxicity and interference with patients' quality of life and resulted in median overall survival figures of approximately four years.
