Abstract

    Purpose: For early detection of breast cancer, tests with high sensitivity and specificity are needed. Metabolomics, the study of chemical processesinvolving metabolites, can be used to identify diagnostic biomarkers for a variety of types of cancers. In this study we identified biomarkersof breast cancer by profiling urinary metabolites.

    Methods: We performed metabolite profiling of 30 urine samples from 14 patientswith breast cancer and 16 healthy controls by liquid chromatography–mass spectrometry. An orthogonal partial least squares-discriminantanalysis (OPLS-DA), Student’s t-test, and receiver operating characteristic (ROC) analysis were performed to identify metabolites that werepotential diagnostic biomarkers for breast cancer.

    Results: The OPLS-DA showed clear separation between the two groups. Of the 95 metabolitesdetected, 24 potential biomarkers were identified by Student’s t-test. A ROC analysis showed that concentrations of N-(2-furoyl)glycine, histidine, and D-tagarose were significantly higher (area under the ROC curve [AUC] >0.7) and those of trigonellinamide, L-galacto-2-heptulose, creatinine, and xanthine were significantly lower (AUC ≥0.8) in the patients with breast cancer than in the healthy controls.

    Conclusion: Measurement of the concentrations of urinary metabolites can be used to screen for early breast cancer. We plan to explore diagnosticbiomarkers of breast cancer in blood and urine further in a larger study.
