Transoral laser microsurgery for early and moderately advanced laryngeal cancers: outcomes from a single centralised United Kingdom centre.

Transoral laser microsurgery (TLM) represents an important treatment for selected laryngeal cancers. Utilisation of TLM, however, is highly variable between United Kingdom (UK) centres, and published data relating to its use in the UK is scarce. We report outcomes from our tertiary referral centre, and highlight lessons learned. Patients undergoing primary TLM for laryngeal cancer with curative intent (2007-2011) were studied retrospectively. Survival analyses were evaluated using the Kaplan-Meier method and log-rank statistics used to examine the influence of several variables. Overall, 170 cases were included-153 glottic and 17 supraglottic. Median follow-up was 39 months (range 14-79 months). Respective 3-year local control (LC), overall survival (OS), disease-specific survival (DSS), and disease-free survival were 92, 92, 98, and 86 % for glottic carcinomas. Three-year LC and OS were both 88 % for supraglottic carcinomas. For glottic cases, a significant impact of pT stage on DSS was observed, and of age on OS. Median hospital stay was one and 19 days for glottic and supraglottic cases respectively, with respective 3-year laryngeal preservation rates of 97 and 94 %, and tracheostomy rates of 0 and 29 %. One patient in the glottic group and four in the supraglottic group failed to regain swallowing function post-operatively, remaining either PEG dependent or undergoing functional total laryngectomy. Our series confirms the oncological and functional efficacy of TLM, offering a unique large-scale UK perspective. Our experience indicates, however, that treatment of larger supraglottic tumours should be considered carefully, as functional outcomes may be compromised. [ABSTRACT FROM AUTHOR]
