ZNF154 and nasopharyngeal carcinoma: Consistent with our observations, Kaplan–Meier analysis also showed that hypermethylation of the ZNF154 promoter was associated with significantly poorer disease-free survival (p = 0.032) and distant metastasis-free survival (p = 0.040) among patients with locoregionally advanced nasopharyngeal carcinoma (NPC) [20].
