The paper is based on analysis of the results of ultrasound investigation of 67 patients with esophageal cancer with metastatic involvement of abdominal and retroperitoneal lymph nodes verified at operation. For effective diagnosis of these changes during ultrasound scanning one should observe the main methodological principles and methods including polyprojection, polyposition and staging of investigation. It should be noted that unchanged lymph nodes cannot be visualized.

In clinical oncology, outpatient ultrasonic investigation helps to assess the nature of the tumor and the spread of malignancy with a high degree of accuracy, so that an adequate treatment could be chosen and initiated as early as possible, and monitored echographically, which is expected to improve its long-term results.
