Herzen Moscow Oncology Research Institute, class: OTHER_GOV, collaborators name: National Medical Research Radiological Centre of the Ministry of Health of Russia, descriptionModule briefSummary: Gastric cancer is still one of the main health care issue and gastrectomy with lymph node dissection is the only chance to be cure. Trials show that the postoperative course differs significantly between eastern and western centers, as well as between clinics within Russian Federation. Postoperative 30-day postoperative mortality after gastric cancer surgery ranges from 1% to 5%, and postoperative complication rates range from 10% to 40%. To improve the quality of further studies and recommendations for standardization of surgical treatment of gastric cancer and its complications, there is a need to study the differences in 90-day postoperative morbidity and mortality in different clinics and centers of the Russian Federation., conditionsModule conditions: Gastric Cancer, conditions: Siewert Type III Adenocarcinoma of Esophagogastric Junction, conditions: Stomach Cancer, designModule studyType: OBSERVATIONAL, designInfo observationalModel: COHORT, timePerspective: PROSPECTIVE, enrollmentInfo count: 700, type: ESTIMATED, armsInterventionsModule interventions name: Elective Surgery for gastric cancer, outcomesModule primaryOutcomes measure: the type of complications and the incidence of it, eligibilityModule sex: ALL, minimumAge: 18 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: A.S.
