Aim. The work is devoted to the development of less invasive tools for the colorectal cancer (CRC) screening. Methods. Q-PCR and methylation-specific PCR techniques were used in the current work. Results. We have shown that the levels of cell-free plasma DNA are higher in the CRC patients compared with the healthy donors (p < 0.01). Hypermethylation of APC, FHIT, LRRC3B and HIC1 genes was studied in the tumor and plasma samples of CRC patients. Two-stage verification for CRC screening was proposed. Conclusions. We proposed and tested a novel approach for CRC screening based on the determination of cell-free DNA and methylated DNA fragments in the plasma.
