Relationship among Diameter of Lymph Nodes,Metastasis and N Staging in Gastric Carcinoma

Objective To study the relationship among diameter of lymph nodes,metastasis and N staging in gastric carcinoma,combining pathology.Methods Seventy-six patients of gastric cancer were examined by MSCT(multi-slice computerized tomography) before operation.All the lymph nodes were examined and analyzed on the relationship among the diameter of lymph nodes,metastasis and the influence on N staging.Results The accuracy of MSCT to predict N staging was 71.05%.The lymph nodes ≤1cm were infiltrated by cancer in 22.20% and those 1cm in 50.74%.Conclusion MSCT possesses high accuracy in preoperative N staging.But the relationship between lymph nodes' metastasis and N staging needs more studies.
