ERCC1 and TS levels were detected in all tumours, with median gene expression relative to housekeeping β-actin for ERCC1 of 0.039 (range 0.001–5.23, 95% confidence interval (CI): 0.26–0.83) and for TS of 8.83 (range 0.72–78.79, 95% CI: 8.03–12.34). This evidence concerns the gene ERCC1 and neoplasm.
