title: Risk factors associated with splenic hilar lymph node metastasis in patients with advanced gastric cancer in northwest China.
abstract: There are plenty of risk factors associated with splenic hilar lymph node metastasis (SHLNM) in patients with advanced gastric cancer (AGC). Whereas, their main influencing factors have not reached a consensus yet. The aim of the study is to investigate the related clinicopathological factors influencing SHLNM in AGC. A retrospective study was performed to investigate 150 patients who underwent D2 curative partial or total gastrectomy for gastric carcinoma from January 2007 to November 2012. Clinicopathological factors were analyzed by univariate and multivariate analysis. A total of 10.7% (16/150) of the patients had SHLNM. The overall ratio of metastatic lymph node (positive lymph nodes/lymph nodes harvested) in the splenic hilum was 17.5% (38/217). Univariate analysis results showed SHLNM was related with depth of invasion, tumor grade, tumor size, tumor location and Bormann type, with significant difference (P<0.05); Multivariate analysis demonstrated that SHLNM was related with depth of invasion and tumor size, with significant difference (P<0.05). Consequently, depth of invasion, tumor grade, tumor size, tumor location and Bormann type were associated with SHLNM in AGC, meanwhile depth of invasion and tumor size are independent risk factors. Preoperative predicting risk factors of SHLNM greatly benefits making more rational surgical scheme of treating AGC.
