Prognostic impact of metastatic lymph node ratio on gastric cancer after curative distal gastrectomy

摘要

AIM:To investigate the prognostic impact of metastatic lymph node ratio(rN) on gastric cancer after curative distal gastrectomy.METHODS:A total of 634 gastric cancer patients who underwent curative resection(R0) of lymph nodes at distal gastrectomy in 1995-2004.Correlations between positive nodes and retrieved nodes,between rN and retrieved nodes,and between rN and negative lymph node(LN) count were analyzed respectively.Prognostic factors were identif ied by univariate and multivariate analyses.Staging acc...
