Introduction:

Laryngeal cancer is the most prevalent malignant tumor in Otorhinolaryngology. Glottic topography is the most frequent in Uruguay and is usually detected in early stages given the early and sustained manifestation of dysphonia. The objective of this study is to analyze disease-free survival (DFS) and overall survival (OS) of patients with stage T1N0M0 glottic laryngeal cancer at 4 institutions in Montevideo.

Methodology:

The mean OS and DFS of 55 patients diagnosed with T1 glottic cancer between 2009 and 2019 were retrospectively analyzed. Kaplan-Meier method was used to calculate survival. The prognostic effect of certain variables of interest on OS was also studied using univariate and multivariate analysis.

Results:

In this study, mean odds survival (OS) for T1N0M0 glottic cancer was 7.706 years (CI 95% 6.63 - 8.78). At 5 years, OS was 77.5% (± 7%) and at 10 years was 62% (± 9.8%). Disease free survival (DFS) was 74.6% ± (7.5%) at 5 years and 63.1% (± 9.8%), at 10 years. Median OS and DFS for the groups were not reached.

Conclusions:

OS and DFS in our medium is comparable to that reported in the international literature. The median OS and DFS were not reached, so it can be stated that this disease has, when appropriate treatment is performed, a good vital prognosis at 10 years. Longer follow-up is required to determine the median OS and DFS of the study groups.
