We analyzed the influence of codon 751 Lys-->Gln polymorphism of XPD on its protein expression levels, clinico-pathological features, and outcome of 188 Chinese patients with metastatic colorectal carcinoma (CRC) that had been treated with first-line Oxaliplatin + Leucovorin + 5-Fluorouracil (FOLFOX-4) chemotherapy.
The SNPs, Ile105Val for GSTP1 and Lys751Gln for ERCC2, may affect the efficiency of oxaliplatin in patients treated with an oxaliplatin-based regimen for metastatic colorectal carcinoma.
