Objective To study the prognostic significance of abnormal expression of p53 and nm23 in gastric cancer.Methods With LSAB immunohistochemical methods,209 cases of gastric cancer was studied.Results The abnormal expression rate of p53 and nm23 is 49.76% and 57.42% ,respectively.The presence of p53 and nm23 protein was not correlated with the sex and age of the patients,the location and size of the tumor,but they correlated with tumor lymphnode metastasis,and patients′ prognosis.Conclusions The abn...
