Abstract
Survival of in patients with gastric carcinoma depends on biological characteristics and staging. At present, widely used in clinical tumor stage is TNM stage. In addition to TNM stage, and prognosis of gastric carcinoma index of concern, such as PNI. The mechanism of PIN is unclear, which have yet to be explored. PNI was closely related to tumor size, depth of invasion, lymph node metastasis, TNM stage, lymphatic vessel and blood vessel invasion, positive surgical margins. However, PNI showed no correlation to age, gender, tumor location, and distant metastasis. PNI is not an independent prognostic factor, despite the prognostic value of PNI. PNI may improve accuracy of the staging of gastric carcinoma, a positive effect on the improvement of means of treatment of gastric cancer.关键词
