Endoscopy capabilities in diagnostics of intramural lymphogenous metastasis in esophageal cancer and esophagogastric junction cancer

The purpose of this article is to demonstrate the experience of the Astrakhan Regional Clinical Oncology Dispensary in diagnosing intramural metastasis of tumors of the esophagus and prostomial parts of the stomach, as well as to emphasize the importance of correctly assessing the extent of tumor damage to determine further treatment tactics. Materials and methods. 630 endoscopic examinations were performed on 570 patients with malignant tumors of the esophagus and proximal parts of the stomach with transition to the area of the esophagogastric junction and esophagus (ICD-O-3 C15.0, 3-5, C 16.0) Results. The endoscopic picture of intramural metastases is diverse, but most often they were multiple or single elevated or flat-elevated neoplasms with a submucosal location, a predominant size of 3-5 mm, mainly with clear contours, grayish-pink or grayish-yellow color, dense consistency. Conclusion. Detection of intramural metastases affects the determination of disease staging and, accordingly, the development of treatment strategy.
