Clinical analysis of early gastric cancer in 338 cases

Objective To find out the relationship between lymph node metastasis and clinical pathological specificity, the prognostic factors for the purpose of improving survival of early gastric cancer (EGC) and quality of life. Methods The clinical data of the 338 EGC patients from July 1999 to June 2009 was analyzed retrospectively, includirg the possible relationship of lymph node metastasis, the size of tumor,types of histopathology,depth of infiltration. Using Kaplan-Meier method to process suvival rate,immunohistochemistry method to detect the micrometastasis. Results Lymphnode metastasis was relative to the size of tumor, depth of infiltration (P < 0.05 or < 0.01). Total 5-year survival rate was 92.1%, intramucosa 5-year survival rate 97.1%, submucosa 5-year survival rate was 85.7% in 63 followed up patients, the survival rate of EGC was related with depth of infiltration and size of tumor (P = 0.043,0.004). Conclusion By precisely estimating depth of infiltration, the size of tumor and correct estimating the state of lymph node metastasis, choosing right 5-year surgical protocol can improve EGC survival rate and prognosis.
