Abstract
We study the possibilities of radionuclide methods of research for identification of sentinel lymph nodes (SLN) in gastric cancer. As a result of the intraoperative radiometric research the SLN were identified in all 48 patients. The study of distant lymph nodes reveals the presence of a metastatic lesion of SLN in 27 patients (56.2 %). In 21 patients (43.8 %) there was no metastatic lesion of SLN. Intraoperative radiometric indication allows to determine the "sentinel" lymph nodes with a sensitivity of 100% and a specificity of 100%. The study of "sentinel" lymph nodes is indicated for patients with depth of invasion of T1-T2 and tumor size of less than 3 cm.
