Eight single nucleotide polymorphisms in ERCC2, XPC, XPA, ERCC1, ERCC4 and ERCC5 genes were analyzed in 91 patients diagnosed with osteosarcoma and treated with cisplatin….In addition, carrying at least one ERCC2 Lys751GlnG allele was significantly associated with shorter event-free survival (median=184 months, compared with 240 months for TT homozygotes; hazard ratio=5.76, 95% confidence interval=1.30–25.55; P-value=0.021).
