[PECULIARITIES OF TREATMENT OF DISTRIBUTED FORMS OF THORACIC PART OF ESOPHAGEAL CANCER].

The aim of this study is to evaluate the methods of treatment of thoracic part of esophageal cancer and to predict the results of treatment depending on the factors of the prognosis. The results of treatment of 366 patients with cancer of the thoracic part of esophagus for 10 years (2007-2016) on the basis of the department of thoracic oncology of the Karaganda oncological dispensary were studied. The overall five-year survival rate, regardless of the method of treatment, was only 8.72% (28 of 321), and in the 6-10 year period 8.41% (27 of 321) lived, p <0.05. Analysis of the overall survival of patients with cancer of the thoracic part of esophagus showed that the method of treatment does not have a significant effect on life expectancy. A multivariate analysis of 19 grades that affect the prognosis of the disease was carried out. Radical type of treatment of the middle and lower thoracic esophagus is surgical, in which the median of cumulative survival is 19 months. Traditional radiotherapy should be used in a limited way, as it is palliative, with a median survival of no more than 9 months. The leading factor in the prognosis for thoracic part of esophageal cancer is the presence of regional metastases, on which the choice of method of treatment depends.
