Abstract

BACKGROUND:

The objective of this study was to evaluate the outcomes of transoral laser microsurgery (TLM) in T3 laryngeal carcinomas and to identify prognostic factors for survival and laryngeal preservation.

METHODS:

This study aimed to provide a retrospective analysis of 147 consecutive patients, evaluating their overall survival, disease-specific survival, laryngectomy-free survival, and function preservation rate.

RESULTS:

Five-year overall, disease-specific, and laryngectomy-free survivals were 53.1%, 70.2%, and 62.3%, respectively. Disease-specific survival differed between glottic and supraglottic tumors (86.3% vs 61.8%; p = .015). Function preservation was 65.5% in supraglottic and 49.1% in glottic tumors (p = .002). Disease-specific survival was not related to pre-epiglottic involvement, cord fixation, or focal cartilage infiltration (p > .05). Vocal cord fixation and cartilage infiltration were independent negative prognostic factors for organ preservation (odds ratio [OR] = 0.184; 95% confidence interval [CI] = 0.082-0.411; p = .000 and OR = 0.331; 95% CI = 0.139-0.789; p = .013, respectively).

CONCLUSION:

Our conclusion is that TLM is a good alternative in a large number of T3 laryngeal tumors, with adequate survival and organ preservation rates above 60%.
