ObjectiveTo study and analyse the correlation between biologic behavior and clinical factors in gastric cancer.MethodsClinical and pathological study of carcinoma of stomach were retrospectively made in 1034 patients. ResultsIn this series,148 of 1034 patients (14.3%) were early gastric cancer.The frequency of lymph nodes metastasis was higher in proximal gastric cancer than distal (P＜0.0001).Similar frequency can also be seen in the tumor of larger diameter (P＜0.01),deeper invasion (P＜0.0001) and poor differentiation (P=0.004).Some difference in ages and sex of patients may be found on the invasion (P=0.003),differentiation (P＜0.0001),site (P＜0.001) and frequency of lymph nodes metastasis of the tumor (P=0.01).In multifactorial multivariate linear regression analysis,the site of tumor (P=0.003),diameter of tumor (P＜0.0001),depth of tumor infiltration (P＜0.0001) and the cell differentiation showed significant association with lymph node metastasis,in which the female patient had more lymph node metastasis than male (P＜0.001).Depth of tumor infiltration was the most important factor in lymph node metastasis.Numbers of lymph nodes resected were much more in total and distal gastrectomies than that in proximal gastrectomy (P＜0.0001). ConclusionThe results of this study suggest that radical gastrectomy with lymphadenectomy is necessary even in all stages of gastric cancer.
