摘要: Platinum resistance enhances DNA damage repair through nucleotide excision mechanisms involving the cross-complementing group 1 (ERCC1), X-ray (XRCC1), and 2 (ERCC2). We evaluated correlation between expression of these three genes clinical outcomes in patients with rectal cancer receiving FOLFOX-based preoperative chemoradiotherapy (CRT). Using immunohistochemistry, we examined ERCC1, ERCC2, XRCC1 pre-CRT tissues from 86 who had undergone curative resection CRT FOLFOX-4 to identify potential predictors outcomes. Following CRT, 57 29 were classified as responders (pathological tumor regression grade TRG 0 1) poor (TRG 3), respectively. The multivariate analysis revealed that ERCC1 overexpression was correlated a response [p 5 ng/mL) (p = 0.03; OR 6.288; 95% CI 1.198–33.006) independent postoperative relapse. By contrast, ERCC2 did not play predictive roles analyzed patients. ERCC1 is associated CRT. biomarker for identifying can benefit customized treatment programs.
