ERCC1 and colorectal carcinoma: For the univariate analysis, the hazard ratio (HR) for the mRNA expression levels of TS and ERCC1 (logTS: HR = 0.820, 95% CI = 0.600 - 1.117, P = 0.210; logERCC1: HR = 1.054, 95% CI = 0.852 - 1.304, P = 0.638) indicated that there was no significant association of DFS with the mRNA expression levels of TS and ERCC1 in Chinese CRC patients treated with oxaliplatin and 5-FU based adjuvant chemotherapy (Table 2).
