[The status of sequential chemo-/radiotherapy in inoperable head and neck cancers. Personal results and review of the literature]

Abstract

Between March 1986 and October 1987 75 patients with advanced cancer of the head and neck were treated with initial chemotherapy before surgery and/or radiotherapy. Chemotherapy consisted of three courses of cisplatin or carboplatin combined with 5-fluorouracil (5-FU). Three weeks after the last course of chemotherapy 34 patients with unresectable tumours received conventional fractionated radiotherapy (60-64 Gy). Of these 34 patients, 32 were evaluated for response and survival with a minimal follow-up of 3 years (22% stage III, 78% stage IV). As the response to cisplatin/5-FU and carboplatin/5-FU was similar (72% versus 64%), survival rates of both chemotherapeutic regimens are presented together. At the end of sequential chemo-radiotherapy 11 patients (34%) were clinically free of disease with an overall response rate of 69%. The survival after 3 years was 12.5% (4 patients) with a median of 15 months. Disease-free survival was 27% (3/11). These poor results confirm the results of other investigators. They indicate that induction chemotherapy does not improve the results of conventional radiotherapy in unresectable carcinomas of the head and neck, even when using highly effective platinum-containing regimens.
