Abstract

MicroRNA-32 (miR-32) is associated with tumor progression and poor prognosis in certain malignant tumors. However, the function and clinical relevance of miR‑32 in human hepatocellular carcinoma (HCC) has not yet been elucidated. The present study aimed to investigate the expression and prognostic value of miR‑32 from liver samples in patients with HCC. The expression of miR‑32 was analyzed in HCC and healthy tissues using Gene Expression Omnibus datasets. Reverse transcription‑quantitative polymerase chain reaction was used to analyze the levels of miR‑32 mRNA in 154 HCC liver samples, 33 of which were paired with adjacent non‑tumor tissues. The overall survival (OS) rate in patients with HCC was evaluated using Kaplan‑Meier survival analysis, and the factors that may affect the prognosis and survival of patients with HCC were analyzed using univariate (log‑rank test) and multivariate Cox proportional hazard models. The present results demonstrated that miR‑32 expression levels were significantly upregulated in HCC liver biopsies compared with normal tissues (P<0.05). miR‑32 expression was significantly associated with the number of foci and tumor diameter (P<0.05). In addition, Kaplan‑Meier analysis revealed that patients with low miR‑32 expression had longer OS and disease‑free survival compared with those with high miR‑32 expression (P<0.01). Altogether, to the best our knowledge, the present study is the first study to indicate the association between increased miR‑32 expression with HCC progression and poor prognosis in patients. This suggests that miR‑32 may have potential prognostic value and may be used as a tumor biomarker for the diagnosis of patients with HCC.
