Abstract

Objectives: To investigate the prognostic significance of positive margin and disease course in partial laryngectomy for advanced laryngeal carcinoma and radiation failure. Design: Retrospective case control study. Setting: A major tertiary referral centre. Participants: Patients who underwent partial laryngectomy for advanced laryngeal carcinoma or for radiation failure with at least 2 years of follow-up. Main outcome measures: Margin status versus primary treatment and salvage treatment versus disease-free survival and overall survival. Results: Twenty nine patients with sufficient follow-up data were found. Twelve patients had histological positive margin. Five of the 12 patients with a histological positive margin failed surgery as did four patients with clear margins. A positive margin had no effect on disease-free survival (P = 0.287) but was associated with poorer overall survival (P = 0.051). Of 11 patients treated primarily with surgery, recurrence was documented in one of eight with a positive margin and none of three with clear margins. Of 18 patients who underwent surgery secondary to radiation failure, recurrence was documented in all four with a positive margin and 4 of 14 with negative margins. Extended frontolateral resection, performed only in radiation failures, was associated with worse disease-free survival. Conclusions: Non-irradiated patients with involvement of a single margin after partial laryngectomy may be spared total laryngectomy if adjuvant radiation is administered. Patients who fail radiation should undergo radical partial laryngectomy, with conversion to total laryngectomy in those with a positive margin.
