Investigation on the DNA repaired gene polymorphisms and response to chemotherapy and overall survival of osteosarcoma.

ABSTRACT: The aim of the present study was to evaluate the influence of polymorphisms in NER and HRR pathways on the response to cisplatin-based treatment and clinical outcome in osteosarcoma patients. 214 osteosarcoma patients treated with cisplatin-based chemotherapy were collected between January 2008 and January 2011. Genotypes of ERCC1 rs11615, ERCC2 rs1799793 and rs13181, NBN rs709816, RAD51 rs1801320, and XRCC3 rs861539 were conducted by Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP) assay. By conditional logistic regression analysis, patients carrying CC genotype of ERCC1 rs11615 showed a significant more good responder than TT genotype, and the OR (95% CI) was 2.51 (1.02-6.85). In the Cox proportional hazards model, after adjusting for potential confounding fa
