    Abstract:
    Potential values of microRNA152 (miR-152) as a serum diagnostic and prognostic biomarker have not been determined in human osteosarcoma. By detecting the expression of miR-152 among 80 osteosarcoma patients, 20 periostitis patients and 20 healthy individuals using qRT-PCR, we aimed to explore the clinical significance of miR-152 in osteosarcoma patients. The expression of miR-152 was significantly decreased in patients with osteosarcoma compared to patients with periostitis (P<0.01) and healthy controls (P<0.01). The relationship between clinicopathologic characteristics and miR-152 was analyzed by chi-square test. The outcome indicated that miR-152 might be linked with the development of osteosarcoma. Moreover, the receiver operating characteristic (ROC) curve was performed to estimate the diagnostic value of miR-152. The result demonstrated that miR-152 might be a promising diagnostic marker of osteosarcoma with an AUC of 0.956, combing with 92.5% specificity and 96.2% sensitivity. The relationship between miR-152 and overall survival of osteosarcoma patients was analyzed by Kaplan-Meier curve and log rank test. As a result, the survival time of patients with low miR-152 expression was significantly shorter than those with high miR-152 expression (P<0.001). Then Cox regression analysis was used to estimate the prognostic value of miR-152 in osteosarcoma. The outcomes showed that low miR-152 expression (P=0.004) might be a potential independent prognostic marker for osteosarcoma patients. These findings suggested that down-regulation of miR-152 could be considered as a predictor for diagnosis and prognosis of osteosarcoma patients.
