Endolaryngeal surgery in treatment of early-stage cancer in supraglottic laryngeal region

Objectives – to improve the results of surgical treatment of patients with T1-T2 stages of cancer in the supraglottic and ventricular region by using endolaryngeal resections.

Material and methods. The study was held in Samara Regional Clinical Oncology Center from 2011 to 2016. We analysed 97 case histories of patients diagnosed with stage 0-I laryngeal cancer. The patients were divided into 2 groups depending on the selected organ-preserving method of surgical treatment. The patients of the control group were subjected to open resection of the larynx (laryngofissure). While the patients of the main group received the endolaryngeal resection using an endoscopic rack, a suspension system, a laryngoscope, hard endoscopes of 0, 30, 45 degrees, as well as electrosurgical cutting and endolaryngeal instruments.

Results. The duration of the operation, blood loss, and bed day number was significantly less in patients of the main group in comparison with the control group. Also, the percentage of common complications in the main group was lower in relation to the control group. The three-year relapse-free and overall survival was not significantly different between the study groups.

Conclusion. According to our observations, the endolaryngeal resections in treatment of the initial stages of laryngeal cancer do not impair the results of treatment and do not significantly affect the survival of this category of patients.
