Summary:At present, there is no screening test for the early detecting and monitoring of ovarian cancer, one of the most lethal form of gynaecological malig- nancy in the worldwide. In this study, the new methodology for the search of tumor markers of ovarian cancer, involving profiling the low-molec- ular blood plasma proteomes, is developed, unified and approved. The given approach included three basic components: pre-preparation of samples, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and bioinformatics software for mass spectral data process- ing. Opportunities and prospects of the developed approach for the detection of potential ovarian cancer markers were shown. For search of po- tential tumor markers, screening of 40 blood plasma samples from ovarian cancer patients and 48 control samples were carried out. As a result of the present research, peptides/polypeptides which can be used in future for detecting this pathology were found out.
