Abstract:
Objective To study the relationship of different histological types and degrees of infiltration of gastric adenocarcinoma on lymph node metastasis.Methods The clinical data of 1 615 cases of gastric adenocarcinoma were analyzed retrospectively,and the rate and number of lymph node metastasis in different histological types and with different depths of invasion were statistically analyzed.Results There were 46 227 lymph nodes collected from 1615 cases,with an average of 28.62 per case. Lymph node metastasis was found in 1046(64.77%) cases of gastric cancer and 10 173(22.01%) lymph nodes. Different TNM stages showed different rates of metastasis: T1(M)2.78%,T1(SM)13.61%,T2 55.59%,and T3 84.84% respectively,while the metastatic rate for histolgically well-differentiated carcinoma was 50.25%,and for low-differentiated earcinoma was 78.95%,and both had statistically significant difference(P
