Abstract: OBJECTIVE:To observe expression levels of serum exocrine miR-193a and miR-21-5p in patients with osteosarcoma,and to explore their diagnostic and prognostic values. METHODS:A total of 112 osteosarcoma patients who visited our hospital from January 2016 to December 2021 were collected as the study subjects,and 100 healthy people as the controls. From all individuals,5mL peripheral blood were collected from each,and serum samples were isolated for exosomes collection. Expression levels of miR-193a and miR-21-5p were detected by real-time quantitative PCR (qPCR). ROC curves were used to evaluate diagnostic values of miR-193a and miR-21-5p for osteosarcoma,and to analyze their correlation with clinical features and prognosis. RESULTS:Expression levels of miR-193a and miR-21-5p from patients were significantly higher than those from controls (P<0.05). The osteosarcoma diagnosis AUC of miR-193a and miR-21-5p were 0.811 and 0.880,respectively. Their sensitivities were 89.2% and 90.2%,and the specificities were 75.0% and 84.0%,respectively. The osteosarcoma diagnosis AUC of the combined method was 0.901,which was higher than that of the single index. The sensitivity and specificity were 92.1% and 86.5%,respectively. Osteosarcoma patients with high expression levels of miR-193a and miR-21-5p were often associated with advanced TNM stages,risk of distant organ metastasis and worse prognosis (P<0.05). CONCLUSION:The expression levels of miR-193a and miR-21-5p in the serum exosomes from osteosarcoma patients were significantly increased. The increase was associated with advanced TNM stages,higher risk of distant organ metastasis and worse prognosis. Thus,serum secretions of miR-193a and miR-21-5p can be considered as biomarkers for diagnosis and prognosis of osteosarcoma.
