THE ROLE OF RADIATION METHODS IN DIAGNOSIS AND STAGING OF COLORECTAL CANCER

Purpose: assessment of complex radiation diagnosis in the recognition and staging of rectal cancer.

Material and methods. From 2016 for 2017 are examined 66 patients with rectum cancer. X-ray methods (irrigoscopy), MSCT and (or) MRI in combination with intravenous contrast enhancement were used as radiation methods.

Results. Rectal cancer was detected in 66 patients. In the study, the upper ampullar part of the rectum was affected in 14 (21%) patients, the upper-middle-ampullar part in 2 (3%), the middle ampullar one in 26 (39%), the middle- lowera mpullar one in 3 (5%), the lower ampullary in 21 (32%). Results of inspection have allowed not only to establish defeat process, but also to specify his stage in compliance with TNM system. Stage I of the disease was established in 2 (3%) patients, stage II in 22 (33%), stage III in 25 (38%) and stage IV in 17 (26%). Subsequently, 39 (59%) patients were operated on.

Conclusion. Complex radiation diagnosis made it possible to accurately diagnose and localize the tumor process, to establish intra – and extra organ distribution with the defeat of surrounding structures and organs. And finally, to make a choice in favor of this or that surgical intervention, and also to determine the necessity of its combination with chemoradiotherapy.
