Mitomycin and fluorouracil in combination with concomitant radiotherapy: a potentially curable approach for locally advanced head and neck squamous cell carcinoma.

OBJECTIVE: The purpose of this study was to evaluate the efficacy of radiotherapy and concurrent mitomycin-C (MC) plus 5-fluorouracil (5FU) infusion in locally advanced squamous cell carcinoma of the head and neck (SCCHN). METHODS: Sixty-nine patients with SCCHN (6 Stage III and 63 Stage IV patients) were treated with external beam radiotherapy (70 Gy) and simultaneous intravenous chemotherapy with 5FU (600 mg/m(2)/day, Days 1-5) and MC (10 mg/m(2), Days 5 and 36). RESULTS: After a mean follow-up of 28.5 months, 59.4% of patients were alive without disease. Complete response was seen in 76.8% of patients. The 3 years overall survival, locoregional relapse-free survival and disease-free survival was 62.3, 63.1[corrected] and 49.5%, respectively. Treatment was well tolerated (Grade III mucositis in 43.5% and Grade II leukopenia in 5.8%). CONCLUSIONS: This concurrent chemoradiotherapy regimen offers a curative option for our patients where primary and nodal disease is fairly large resulting in hypoxic radioresistant tumors.
