The predictive value of tumor lymphocytic infiltration was studied in 186 gastric cancer patients curatively resected. All patients were followed-up for over 10 years. LI was negatively correlated with p-TN stage of disease. A poorer prognosis was detected in patients with minor or no tumor lymphocytic infiltration. LI was an independent prognostic parameter according to the Cox model and logistic regression analysis. These findings suggest that LI should also have been considered in the current staging of gastric cancer.
