Abstract

BACKGROUND:

Survival of patients after curative surgical resection for gastric cancer (GC) remains poor, thus emphasizing the need for better definition of prognostic factors to improve the long-term course of disease.

METHODS:

From 1999 to 2009, 110 patients had curative-intent gastrectomy for adenocarcinoma. Clinicopathological features, Helicobacter pylori infection, dietary habits and lifestyle, and the presence of proinflammatory gene polymorphisms were evaluated.

RESULTS:

At the end of follow-up, 55 deaths had occurred, 48 of them due to GC, whereas the median overall survival (OS) and disease-free survival (DFS) were 62 and 51 months, respectively. From the Kaplan-Meier analysis and log-rank test, statistically significant differences in OS and DFS were found for tumor site (only for DFS), tumor size, lymph node metastasis ratio (NR), and tumor-node-metastasis stage, but not for age, comorbidity, H. pylori infection, cigarette smoking, and IL1B or TNFA polymorphisms. Multivariable Cox regression analysis revealed NR was an independent prognostic factor for OS and DFS. Cardia tumor and patient age 65 years or older were also independent prognostic factors for OS and DFS.

CONCLUSIONS:

Tumor-related factors remain strongest predictors of survival in GC patients after surgery. Particularly, NR was an effective feature in identifying patients at high risk for adverse outcome.
