OBJECTIVE: To determine expressions of MicroRNA-19a-3p (miRNA-19a-3p) and PDCD5 in nasopharyngeal carcinoma (NPC) tissues, and their prognostic potentials in NPC.
PATIENTS AND METHODS: Expressions of miRNA-19a-3p and PDCD5 in NPC tissues and controls were determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The correlation between expressions of miRNA-19a-3p and PDCD5 in NPC was evaluated by Pearson correlation test. Furthermore, potential influences of miRNA-19a-3p and PDCD5 on clinical features of NPC patients were assessed. Through 5-year follow-up, survival analysis in NPC patients was conducted by Kaplan-Meier method. Finally, factors influencing prognosis of NPC were determined using the Cox regression model.
RESULTS: MiRNA-19a-3p was upregulated and PDCD5 was downregulated in NPC tissues. Pearson correlation test uncovered a negative correlation between expression levels of miRNA-19a-3p and PDCD5 in NPC tissues. MiRNA-19a-3p level was correlated with N classification and clinical stage in NPC patients, while PDCD5 level was correlated with T classification, pathological grade and clinical stage. Survival analysis showed poor prognosis in NPC patients expressing high level of miRNA-19a-3p or low level of PDCD5. Cox regression analysis illustrated that N2+3 classification, clinical stage III+IV, high level of miRNA-19a-3p and low level of PDCD5 were independent risk factors for the prognosis of NPC.
CONCLUSIONS: MiRNA-19a-3p is upregulated and PDCD5 is downregulated in NPC tissues. High level of miRNA-19a-3p and low level of PDCD5 are unfavorable for the prognosis of NPC.
