CIP2A and nasopharyngeal carcinoma: In recent years, several molecular biomarkers have been identified to be associated with prognosis in NPC, such as breast cancer metastasis suppressor 1 (BRMS1), metastasis-associated protein 1 (MTA1), Dicer 11, centromere protein-H (CENP-H) and cancerous inhibitor of protein phosphatase 2A (CIP2A) [9-13]; however, prognostic prediction in NPC remains extremely poor [14].
