Abstract

Between 1982 and 1991, 16 patients with recurrent cancer of the nasopharynx were treated with chemotherapy (CT) and radiotherapy (RT). All patients had received prior RT (45-69, 30 Gy). According to rTNM there were three rT2, one rT3 and 12 rT4. 5 patients were N1. Reirradiation (12-46 Gy, mean: 28) started 3-4 weeks after CT (2-6 cycles of different combinations), but 2 cases involved concomitant therapy. Out of 16 patients 7 had complete response (CR) (43.7%), 7 partial response and 2 no response. Statistically significant prognostic factors for obtaining CR were time of relapse and response to initial CT. Median duration of CR was 22+ months (9-64+). Failures at primary site occurred in 3 patients, 2/2 of those receiving CT without platinum compounds and 1/5 of other ones, with statistically significant difference in local recurrence free-survival between the two groups. Two- and 3-year actuarial overall survival were 28% and 10%. Rates of disease-free survival were 17% and 8%, respectively. The acute toxicity was generally mild. No central nervous system damage or radiation-induced myelitis were observed in survivors.
