The positive expression of ERCC Excision Repair 1 (ERCC1; a DNA excision repair protein) also predicted a poor OS (HR = 1.77; 95% CI = 1.48–2.12; p < 0.001) and DFS (HR = 1.60; 95% CI = 1.43–1.79; p < 0.001) in NPC patients [32]. The gene discussed is ERCC1; the disease is nasopharyngeal carcinoma.
