[Analysis of risk factor of perioperative complications in patients with radical gastrectomy for gastric cancer and its influence on prognosis].

Objective: To study the risk factor of perioperative complication in gastric cancer patients with radical therapy and its influence on prognosis.

Methods: Clinical, pathological and follow-up data of 1 148 gastric cancer patients undergoing radical gastrectomy at Tianjin Medical University Affiliated Tumor Hospital between January 2009 and August 2011 were retrospectively collected. Pearson 2 test and Logistic regression analysis were used to analyze the risk factor of perioperative complication.

Effect of the number of positive niduses in extranodal soft tissues on the overall survival of gastric cancer patients.

Background: This study aimed to elucidate the intensive effect of the number of positive niduses in extranodal soft tissues (PNESTs) on the overall survival of gastric cancer (GC) patients after curative gastrectomy.

Methods: The clinicopathological data of 961 GC patients were studied to determine whether increased number of PNESTs was a high-risk factor for the dismal prognosis of GC patients.

Results: Survival analyses revealed that the number of PNESTs was negatively associated with the overall survival (OS) (<0.
