Oncological outcome in advanced laryngeal cancers treated with different modalities in a single institution. A retrospective analysis on 65 cases.

Abstract\r\nBackground: Treatment for laryngeal squamous cell carcinoma (SCC) has been predominantly surgical for decades, but in the last 20 years nonsurgical modalities (radiotherapy), with the aim of organ preservation, also became predominant among advanced stages. Retrospectively evaluating our series of stage III and stage IV laryngeal SCCs, we compared the 2 main therapeutic modalities.\r\n\r\nMethods: Medical records of 65 consecutive patients with advanced laryngeal SCC, from November 2005 to January 2009, were reviewed.\r\n\r\nResults: Among irradiated patients 2-year organ preservation was 86% for cT2, 43% for cT3, and 17% for cT4a (p = .037, Wilcoxon test). With respect to survival, the only significant differences between surgery and radiotherapy were detected among cT4a SCCs (p = .03, Wilcoxon test), in favor of surgery.\r\n\r\nConclusions: The present results confirm the surgical recommendation for cT4a laryngeal SCCs. On the other hand, for T < 4, our results confirm that radiochemotherapy warrants a survival similar to that of total laryngectomy, thus allowing us to preserve the larynx in a relevant number of cases.
