This resembles what observed for the expression of ERCC1 in non small cell lung cancer (NSCLC), where it has been shown that higher ERCC1 levels were correlated with a better prognosis [50], [51], but was also higher levels of ERCC1 were a marker of resistance to a platinum containing regimens [50]. This evidence concerns the gene ERCC1 and non-small cell lung carcinoma.
