The Relationship Between The Rate Of Lymph Node Metastasis And T Stage Of Gastric Cancer Patients

Objective: To evaluate the prognostic value of metastatic lymph node ration(MLNR)in gastric cancer patients by T stage.Methods: Clinical data of 535 patients with gastric cancer undergoing radical gastrectomy and lymphadenectomy were reviewed.MLR classification was compared with pN classification in terms of the accuracy and valid value.The MLR in T stage patients were analyzed retrospectively.Results: The MLR was assessed in 4 categories:0,0.01~0.09,0.1~0.2,>0.2.Kaplan-Meier survival analysis showed that MLR significantly influenced the postoperative survival time and Cox proportional hazard regression model analysis showed MLR Was an independent poor prognostic factor.There Was no significant difference between the area under the receiver working characteristic curve of MLR and metastatic lymph nodes number in predicting patients 5 year death postoperatively.Conclusions: MLR is an independent prognostic factor of patients with gastric cancer.MLR is more reliable factor in predicting the prognosis of gastric cancer patients than the number of metastatic lymph nodes.especially for T2~T3 stage gastric cancer patients.
