RT Journal Article SR Electronic A1 Stary, Lubomir A1 Mezerova, Kristyna A1 Skalicky, Pavel A1 Zboril, Pavel A1 Raclavsky, Vladislav T1 Are we any closer to screening for colorectal cancer using microbial markers?A critical review JF Biomedical papers YR 2017 VO 161 IS 4 SP 333 OP 338 DO 10.5507/bp.2017.051 UL https://biomed.papers.upol.cz/artkey/bio-201704-0001.php AB The role of gut microbiota in the development of sporadic colorectal cancer (CRC) is supported by a number of studies, however, the conclusiveness of published metagenomic studies is questioned by technical pitfalls and limited by small cohort sizes. In this review, we evaluate the current knowledge critically and outline practical solutions. We also list candidate CRC risk markers that are - in our opinion - well supported by available data and thus deserve clinical validation. Last but not least, we summarise available knowledge useful for improving care for patients immediately.
