Possibility of predicting the results of the surgical treatment of cancer of the thoracic portion of the esophagus

Within a 18-year period in the clinic 273 patients were subjected to radical surgery for cancer of the thoracic esophagus. 206 patients were discharged from the clinic. The survival rate for 5 years and longer was noted in 58 patients. The data and results of the treatment depending on a sum of clinical signs were treated mathematically. It is noted that the patients' survival is influenced by such factors as sex, the stage of the disease, the morphological structure of tumor, the character of course, tumor size and spread, the type of surgical intervention. An advanced course, changes in blood presence of metastases do not seem to be the reason for cancellation of the operation.
