概要	BACKGROUND:This study was undertaken to analyze the functional results, complications, local control rates, and survival in patients undergoing conservation surgery for squamous cell carcinoma (SCC) of the larynx as a salvage procedure for recurrent tumors after previous radiotherapy.METHODS:Twenty-one patients underwent frontolateral laryngectomy for radiation failure, T1 and T2 glottic SCC, at the Cancer Institute Hospital, Tokyo, from 1976 to 1991. All patients were men between the ages of 42 and 83 years. The disease-free interval ranged from 1 to 87 months (median, 26 months). The stage at initial treatment was T1 in 17 patients and T2 in four patients. Local recurrence developed in three patients.RESULTS:The rate of local control was influenced by a surgical margin of less than 1 mm (p < 0.05). Overall voice preservation was achieved in 86% of the patients. The 5-year and 10-year survival rates following frontolateral laryngectomy were 86% and 70%, respectively. Maximum phonation time after surgery ranged from 4 to 18 seconds (median, 8.1 seconds).CONCLUSIONS:These results indicate that in carefully selected cases, frontolateral laryngectomy may be used for treating radiation failure stage I or II vocal cord carcinomas with good success. Careful follow-up may be necessary in patients with a close surgical margin.
