Abstract
PURPOSE: Treatment with conventional radiotherapy alone for local control of T2 glottic cancer (T2GC) is insufficient. To improve local control of T2GC, we have simultaneously administered continuous intravenous infusions of low-dose cisplatin and 5-fluorouracil (5-FU) in combination with irradiation. MATERIALS AND METHODS: We performed this combination therapy in a total of 11 consecutive patients with previously untreated invasive squamous cell carcinoma (T2GC). Cisplatin was administered at 4 mg/m2/day and 5-FU at 200 mg/m2/day for 120 h, except during weekends, beginning on the day irradiation with a once-daily fraction at 2 Gy was started. RESULTS: An initial local control rate of the primary tumor was achieved in 10 of the 11 patients (91%), and ultimate laryngeal preservation by cordectomy was achieved in all cases. Regarding adverse reactions, grade 3 or 4 hemotoxicity did not develop in any of the patients. Grade 3 laryngitis was observed in four patients (36%), but none of these patients required interruption of treatment owing to acute laryngeal reactions. CONCLUSION: Instead of radiotherapy alone, this combination chemoradiotherapy is suggested with the possibility of improving local control of T2GCs.
