Popis: The study objective – to analyze the treatment results and prognostic factors of survival in patients with locally advanced laryngeal cancer who received surgical treatment and chemoradiotherapy.Materials and methods. The retrospective study included patients with locally advanced laryngeal cancer treated at the N. N. Petrov National medical Research Center of Oncology, Ministry of Health of Russia in the period from 2009 to 2018. The patients included in the study were divided into 2 equal groups (74 patients were included in each group) depending of treatment: surgery with postoperative radiation therapy combined with chemotherapy (group 1) and concurrent chemoradiation therapy and subsequent surgical treatment in case of incomplete response to treatment or disease progression (group 2). The endpoints of the study were general and relapse-free survival.Results. One hundred and forty-eight patients were included in the study: 74 patients in group 1 and 74 patients in the group 2. The median overall survival in the surgical treatment group was 45 months, in the chemoradiotherapy group – 44.6 months, and the overall 5-year survival for the group 1 and the group 2 were 39.3 (95 % confidence interval (CI) 26.1–59.2), and 59.2 % (95 % CI 45.3–77.2), respectively. The relapse-free 5-year survival rate for the surgical treatment group and the chemoradiotherapy group was 36.8 (95 % CI 25.1–53.8), and 53.9 % (95 % CI 40.7–71.4), respectively.Conclusion. There were no significant differences in overall and relapse-free survival. Metastatic lesion of the neck lymph nodes (N2–3), invasion of laryngeal cartilage, invasion of the thyroid gland and the spread of the tumor to the larynx are statistically significantly associated with lower overall and relapse-free survival.
