The Expression and Significance of Multidrug Resistant Gene mdr1 in Hepatocellular Carcinoma / 中国普外基础与临床杂志

Objective To explore the relationship between mdr1 gene expression of hepatocellular carcinoma (HCC) and pathological characteristics,chemotherapy and prognosis. Methods The mdr1 gene expression of HCC in 56 patients with the methods of immunohistochemistry was studied. The results were analysed with the pathological data by statistic methods. Results The positive expression of mdr1 gene in cancer tissues and pericancerous tissues of HCC were 30/56(53.6%) and 19/56 (33.9%) respectively. The difference was statistically significant (? 2=4.39, P
