Computed tomography (CT) findings were compared with operative ones for 50 patients with esophageal and proximal gastric cancer. In diagnosis of metastases to the upper abdominal and retroperitoneal lymph nodes ST sensitivity reached 93.3%, specificity 85% and accuracy 90.3%. The best diagnostic results were obtained in detection of metastases to the nodes of the celiac trunk branch and paraaortal fat (94.2%). Lower CT resolution appeared in diagnosis of perigastric node metastatic involvement in the primary tumor location in the proximal stomach.
The examination of 170 patients with cancer of the esophagus and proximal stomach made it possible to specify x-ray, ultrasonic and CT signs of cancer metastases to the upper abdomen and retroperitoneum. A scheme of radiodiagnosis of these metastases is suggested. The diagnostic value of x-ray, echography and CT was considered in relation to various lymph nodes involvement.

An examination of 1525 patients has established that the main clinical symptoms of the perifocal inflammatory process are: hyperthermia of different degrees, leukocytosis and higher ESR, pain in the rectum area and in the abdomen, tenderness and pasty tissues in the tumor area. The roentgenological symptoms are: the presence of fistulas, considerable dilatation of presacral space not corresponding to the tumor size, pathological "cellularity" of the paraintestinal tissues.
