Abstract

Background: Laryngeal early glottic tumors can benefit from different treatment modalities, including transoral laser microsurgery, open partial horizontal laryngectomy (OPHL), and radiotherapy. However, the treatment of early glottic tumors with the involvement of the anterior commissure remains controversial. The studies about the role of anterior commissure involvement in oncologic outcomes in patients with early glottic cancer treated with supracricoid laryngectomy (SCL) are very few. For this reason, we conducted a retrospective study to evaluate local recurrence-free survival and specific survival in patients with and without involvement of the anterior commissure who underwent SCL with cricohyoidoepiglottopexy.

Methods: This retrospective study has been carried out on patients with T1b-T2 glottic squamous cell carcinoma submitted to SCL with cricohyoidoepiglottopexy. The patients' demographic and clinical data were collected, and the histological findings of the surgical specimens were reviewed to identify patients who had involvement of the anterior commissure.

Results: A total of 72 patients were included in the study; two of them were female and 70 were male. The mean age at diagnosis was 61.5±8.0 SD years. In 26 of the 72 (36.2%) patients, anterior commissure was not pathologically involved (group A), while in 46 (63.8%) patients, it was involved (group B). The 5-year local recurrence-free survival rate was 96.1% and 93.48% in groups A and B, respectively, P=0.09. The 5-year disease-specific survival rate was 92.31% and 95.65% in groups A and B, respectively, P=0.057.

Conclusion: SCL with cricohyoidoepiglottopexy seems to be an adequate treatment modality, even for T1b-T2 glottic tumors with anterior commissure involvement.

Keywords: cricohyoidoepiglottopexy; laryngeal cancer; open partial horizontal laryngectomy; supracricoid laryngectomy.
