This neoplasm occurs mostly among people older than 50, and the incidence rate is growing each year. This calls for a need for new methods of detection of this type of cancer. Transferrin Test (Tf) can be an effective and reliable method for diagnosing colorectal cancer. HTSA Fecal Occult Blood Test using the immunochemical IFOBT/FIT method in Khanty-Mansiysk Region - Yugra DETECTION Immunochemical fecal occult blood test OCCULT bleeding in various intestine areas iFOBT/FIT Fecal Hemoglobin (Hb) – high levels of Hb indicate the damage of lower areas of intestine. Hb Fecal Transferrin (Tf) - high levels of Tf indicate the Tf damage of higher areas of intestine . Besides, Fecal Tf allows avoiding the false-negative results for Hb. © “Diagnosis” Yoshinori Takashima, Takao Shimada, Tamotsu Yokozawa – 2015; 2(1): 53-59. (Hemoglobin Transferrin Simultaneous Assay) a combination of the quantification of fecal hemoglobin (Hb) and fecal transferrin (Tf) has the highest current accuracy level: 96% for patients with cancer and 88% for patients with precancerous conditions. Transferrin – in the LOINC system In may 2017 fecal transferrin was introduced to the international database and universal standard for identification of medical doctor’s and laboratory examinations – LOINC, and it was given a code 86271-4. LOINC is used for standardized presentation of medical terminology in the field of laboratory research and clinical observation for the purpose of electronic exchange and the collection of clinical data obtained from various information systems.

Caprin, V.V. Starinski, G.V. Petrova - Moscow, 2012-2016 Conclusions: The data over the 5 year period in Khanty-Mansiysk region are represented above. Due to the 2-days HTSA method use (fecal hemoglobin and transferrin simultaneous assay) detection of colon cancer at the 1 stage has grown three times. Two-days HTSA method helped to increase detection of rectum cancer two times. As a result CRC mortality rate remained at a low level.
