Prognostic relevance of systematic lymph node dissection in gastric carcinoma. German Gastric Carcinoma Study Group.

摘要: In a prospective multicentre study of 2394 patients with gastric carcinoma the prognostic relevance systematic lymph node dissection was evaluated. Of 1654 undergoing resection, 558 had standard dissection, defined as fewer than 26 nodes in specimen, and 1096 underwent radical lymphadenectomy, i.e. or more specimen. Radical significantly improved survival rate Union Internacional Contra la Cancrum (UICC) stages II IIIA tumours. Multivariate analysis identified an independent factor subgroups UICC tumour IIA. conferred no advantage pN2 There significant difference morbidity mortality rates between dissection. lymphadenectomy improves cancer IIIA, should be recommended treatment for such patients.
