EARLY DIAGNOSIS OF COLORECTAL CANCER

The diagnosis and treatment of colonic precancers and the detection of early-stage colorectal cancer (CRC) are able to reduce CRC morbidity and mortality. Elaboration of unified protocols for screening and diagnostic tactics in the detection of CRC will help optimize the use of early primary diagnostic methods for colonic epithelial tumors (colonoscopy, fecal occult blood test, fecal immunochemical test, virtual colonoscopy, determination of the molecular genetic profile of enterocytes in the feces) and confirmatory clinical diagnostic techniques (echography, computed tomography, magnetic resonance imaging, positron emission tomography). The use of unified standards for early diagnosis will increase the detection rate of early-stage colonic tumor diseases and will be able to choose an optimal treatment policy for CRC, which will, in the long run, contribute to the reduction of CRC mortality rates.
