[On the possibilities for the traditional x-ray diagnosis of cancer of the middle and lower thoracic esophagus].

Traditional X-ray and endoscopy methods of research have limited abilities in expotion of the all parameters of the esophagus tumor. It becomes clear, that this method is not satisfactory enough. It's clear that without information about all parameters of cancer infiltration surgical and combined (operation + radiotherapy) treatment do not give desired result. With an objective to study this matter, 290 X-ray pictures of 150 patients with cancer of the middle and lower mediastinum sections of esophagus and were getting treatment, were studied and analyzed. It was identified, that correspondingly to the filling defect with the esophagus cancer on the phone of the light stripe of mediastinum the external contours give the full picture of the tumor infiltration. Rehabilitation of esophagus function during the process of X-ray therapy in parallel with the deduction of the shadow of the tumor infiltration the phone of mediastinum, give a floor to our suspecion, that abovementioned shadow is the anatomic substrate of the esophagus tumor. It is very important to reveal all tumor's parameters in diagnostics and radiation therapy of the esophagus cancer.
