AbstractAnti-differentiation non-coding RNA (ANCR), a long non-coding RNA, is involved in the development, progression and metastasis of various human cancers. However, its clinical significance in nasopharyngeal carcinoma (NPC) still remains unknown. This study aimed to investigate ANCR expression and its clinical significance in NPC.Totally, 96 NPC tissues and 24 non-cancerous nasopharyngeal mucosa tissues were used. The levels of ANCR were determined by qRT-PCR. Relationship of ANCR with patient clinical characteristics, disease-free survival and overall survival (OS) was evaluated.ANCR expression was increased in NPC tissues compared to non-cancerous nasopharyngeal mucosae. ANCR expression was significantly related to lymph node metastasis, clinical stage, and tumor differentiation (P < .05). Kaplan-Meier survival analysis revealed that high level of ANCR expression was significantly associated with poor disease-free survival but not with OS in NPC patients. Univariate analysis showed a significant association between increased ANCR expression and adverse OS (P < .05), but multivariate analysis suggested that ANCR could not be used as an independent prognostic factor for NPC patients.ANCR is involved in the development and progression of NPC, but whether it can be used as an effective therapeutic target for NPC needs further study.Copyright © 2021 the Author(s).
