BACKGROUND: The purpose of this study was to study the effect of intensive targeted chemoradiation in a group of patients with head and neck cancer with stage IV inoperable disease. METHODS: We examined 79 patients with inoperable stage IV head and neck cancer receiving intra-arterial infusion of high-dose cisplatin (150 mg/m(2)) on days 2, 9, 16, and 23 concomitant with delivery of external beam radiotherapy (total dose, 70 Gy; 2 Gy, 35 fractions; 1 fraction/day for 7 weeks). Sodium thiosulfate was administered intravenously to provide effective cisplatin neutralization. RESULTS: Four patients were not assessable. Complete local tumor response was achieved in 72 patients (91%) and a partial response in three patients. The complete response rate of neck node metastases was 90%. The 1- and 2-year locoregional control rates were 82% and 69%, respectively. The median overall survival time was 2.2 years, with a 3-year overall survival probability of 43%. Acute toxicities were as follows: grade III/IV hematologic toxicity (22%/16%), grade III/IV nephrotoxicity (0%), grade III mucositis (43%), grade III skin reactions (24%), grade III toxicity of the upper gastrointestinal tract (57%), grade III nausea (20%), and grade III subjective hearing loss (10%). Grade V toxicity (treatment-related deaths) was 3.8%. Six (18%) of 33 patients with complete remission needed tube feeding 2 years after treatment without intercurrent salvage surgery. CONCLUSIONS: Supradose superselective intra-arterial cisplatin and concomitant radiation is an effective organ-preserving therapy in an unfavorable group of patients. Our series confirms encouraging results reported previously. This regimen is justified in unresectable patients despite the substantial toxicity.
