Endoscopic diagnosis and treatment of primary multiple noninvasive malignant neoplasms of the stomach: clinical case

This clinical case describes a rare combination of early stage cancer and sporadic neuroendocrine tumor in stomach. The patient 57 years old admitted to P. A. Hertsen Moscow Oncology Research Institute for diagnostics and treatment for the gastric adenoma. Upper GI endoscopy performed in P. A. Hertsen Institute, detected two tumors: a sporadic neuroendocrine tumor in the middle part of the body stomach and early cancer in the antrum. With NBI (Narrow-Band Imaging), signs of malignancy were found in both tumors. А plan for therapeutic and diagnostic endoscopic surgical interventions was implemented: two sequential endoscopic submucosal dissection (ESD). This treatment confirmed as radical, according to the results of the pathological examination.
