ERCC1 and non-small cell lung carcinoma: The study of Dong et al. [40] on the expression of ERCC1 and the prognosis of platinum chemotherapy in patients with advanced NSCLC indicates that the 5-year survival rate and median survival time of patients with low expression of ERCC1 are higher than those of patients with high expression, which is consistent with the results of chemosensitivity in this study.
