A simplified metabolomic analysis of dried blood spots in breast cancer patients.
Breast cancer (BC) is among the most commonly diagnosed cancers. Besides mammography, breast ultrasonography and the routinely monitored protein markers, the variations of small molecular metabolites in blood may be of great diagnostic value. This study aimed to quantify specific metabolite markers with potential application in BC detection. The study enrolled 50 participants, 25 BC patients and 25 healthy controls (CTRL). Dried blood spots (DBS) were utilized as biological media and were quantified via a simplified liquid chromatography tandem mass spectrometry (LC-MS/MS) method, used in expanded newborn screening. The targeted metabolomic analysis included 12 amino acids and 32 acylcarnitines. Statistical analysis revealed a significant variation of metabolic profiles between BC patients and CTRL. Among the 44 metabolites, 18 acylcarnitines and 10 amino acids remained significant after Bonferroni correction, showing increase or decrease and enabled classification of BC patients and CTRL. The well-established LC-MS/MS protocol could provide results within few minutes. Therefore, the combination of an easy-to-handle material-DBS and LC-MS/MS protocol could facilitate BC screening/diagnosis and in the next step applied to other cancer patients, as well.
期刊介绍:
The Scandinavian Journal of Clinical and Laboratory Investigation is an international scientific journal covering clinically oriented biochemical and physiological research. Since the launch of the journal in 1949, it has been a forum for international laboratory medicine, closely related to, and edited by, The Scandinavian Society for Clinical Chemistry.
The journal contains peer-reviewed articles, editorials, invited reviews, and short technical notes, as well as several supplements each year. Supplements consist of monographs, and symposium and congress reports covering subjects within clinical chemistry and clinical physiology.
