Abstract

The published data on the predictive value of polymorphism of ERCC1 and XPD in patients with advanced non-small cell lung cancer receiving platinum-based chemotherapy are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. Relevant studies were identified by searching the Medline, Embase, CNKI and American Society of Clinical Oncology abstract databases. Inclusion criteria were patients with advanced NSCLC, received platinum-based chemotherapy, evaluation of polymorphism of ERCC1 and XPD and overall response rate (ORR). A total of 12 studies were included in this meta-analysis. For studies evaluating ERCC1 polymorphism at codon 118, the ORR for the wild-type C/C genotype versus the heterozygous C/T and T/T genotype was 2.17 (95% confidence interval (CI), 1.43–3.33; P = 0.000). For studies evaluating XPD Asp312Asn and XPD Lys751Gln, the pooled OR was 1.33 (95% CI, 0.92–1.91; P = 0.13) and 1.02 (95% CI, 0.72–1.45; P = 0.915), respectively. The results indicated that platinum-based chemotherapy sensitivity was significantly associated with polymorphism of ERCC1 C118T. However, XPD Asp312Asn and XPD Lys751Gln were not predictive makers for platinum-based chemotherapy in patients with advanced NSCLC.
