Епідеміологічна ситуація та аналіз організації спеціалізованої допомоги хворим на рак гортані в Запорізькій області (2001-2015)

Abstract

The incidence of laryngeal cancer of 2001-2015 years among the male population (1354 cases) was much higher than among the female population (77 cases).The highest incidence of laryngeal cancer was observed in men aged 50 to 69 years – 917 cases (67.7%). The highest incidence of laryngeal cancer (37 cases, 48.1%) noted in women older than 60 years. The vast majority of cases (932 patients, 65.1%) were diagnosed in III-IV stages of tumor development and 912 patients (63.7%) only, from 1431 primary patients, received special treatment. Five-year survival rates of patients with first stage cancer of the larynx – 90.9%; at the second stage – 88.1%; at the third stage – 60.4%; at stage IV – 22.6%. The regional metastases were observed mainly in the corner lymph node and nodes along the internal jugular vein, at least in supraclavicular lymph nodes and compared with extended growth or recurrence of cancer of the larynx, a rein a ratio of 1/6.The risk of development of regional metastases of cancer of the larynx correlates with the proliferation (Rs 0.73), localization (Rs 0.67), and the form of a growth (Rs 0.70) and histological structure of tumors (Rs 0.43). Prognosis of laryngeal cancer of the region's population by 2022 – 94 cases per year, with an average error -1.12 and the average percent age error -3.33.
