Combined radiotherapy and chemotherapy in stage T3 and T4 nasopharyngeal carcinoma in children.

Abstract

Twelve children younger than 16 years affected by undifferentiated nasopharyngeal carcinoma (NPC) with advanced primary tumor (T3, T4) were treated with chemotherapy consisting of Adriamycin (ADM [doxorubicin; Adria Laboratories, Columbus, OH]), vincristine (VCR), and cyclophosphamide (CYC), and radiotherapy. Preradiation chemotherapy produced partial responses in eight of ten evaluable patients. Eleven of 12 patients achieved a complete response following radiotherapy. The actuarial 3-year continuous relapse-free survival (CRFS) was 75%. This represents a significant improvement when compared with the 8% rate obtained in a previous series of patients treated with radiotherapy either with or without adjuvant CYC.
