The purpose of the present study was to investigate the serum levels of microRNA (miRNA/miR) -382-3p, -598-3p, -1246 and -184 in breast cancer patients and to assess their feasibility as biomarkers for breast cancer screening. Serum samples were obtained from 100 breast cancer patients and 40 age-matched healthy control subjects in Taizhou Central Hospital (Taizhou, Zhejiang, China) between January 2013 and September 2014. The serum expression levels of miR-382-3p, -598-3p, -1246 and -184 were determined by stem-loop reverse transcription-quantitative polymerase chain reaction. Receiver operating characteristic curves were drawn to evaluate the sensitivity and specificity of the serum miRNA expression levels for the screening of breast cancer. miR-382-3p and -1246 were significantly upregulated in the serum of the breast cancer patients, while miR-598-3p and -184 were significantly downregulated. The sensitivity and specificity to detect breast cancer were as follows: miR-382-3p, 52.0 and 92.5%; miR-598-3p, 95.0 and 85.0%; miR-1246, 93.0 and 75.0%; and miR-184, 87.5 and 71.0%, respectively. The expression levels of the four serum miRNAs were not correlated with the patients' clinical stage. In summary, miR-382-3p, -598-3p, -1246 and -184 are all involved in the development of breast cancer, and are promising biomarkers for breast cancer detection.
