肿瘤耐药是；临床化疗失败的主要原因，经研究发现某些肿瘤耐药是多机制的，单一检测某项指标并不全面，联合检测会提高阳性率，给临床提供更多的耐药信息。近年来，用于检测比较多的是多药耐药基因ＭＤＲ１和其编码的Ｐ－糖蛋白，ＧＳＴ－π。在多药耐药中的作用及其表达情况?
Tumor resistance is the main reason for the failure of clinical chemotherapy, the study found that some of the tumor drug resistance is multi-mechanism, a single test is not comprehensive indicators, the joint test will increase the positive rate, to provide more resistance to clinical information . In recent years, for the detection of multidrug resistance gene MDR1 and its encoded P-glycoprotein, GST-π. The role of multidrug resistance and its expression?
