Abstract
Objective To detect the expression of BAG-1 and p53 in postoperative patients paraffin section of non-snmll cell lung cancer (NSCLC), and retrospectively analyze the relationships of clinical feature and platinum-based chemotherapeutic sensitivity in NSCLC, to further investigate the resistance mechanism of platinum. Methods The expression of BAG-1 and p53 was measured by immunohistochemistry in paraffin sections of 125 NSCLC postoperative patients. The existence and prognosis were analyzed after follow-up. Results BAG-1 and p53 showed high expression in NSCLC (positive rate 64.8 %, 46.7 %); BAG-1 positive or p53 negative expression had survival advantage(P<0.05); The group of BAG-1, p53 negative expression could benefit from platinum-based chemotherapy (P<0.05). Conclusion Expressions of BAG-1, p53 correlates with platinum-based chemotherapeutic sensitivity, and maybe become new types of clinical prognostic indicators and contribute to individualized treatment options for NSCLC. Key words: BAG-1; Genes, p53; Carcinoma, non-small-cell-lung; Platinum; Chemotherapeutic sensitivity
