Does PET-CT Contribute to Sitoreductive Surgery in Advanced Stage Colorectal Cancers?

Abstract

Colorectal cancers are seen at a high rate in developed countries. The 5-year survival rate varies according to the stage of the disease at the time of diagnosis. Therefore, it is very important to detect the disease at an early stage, to stage it correctly and to determine the appropriate treatment options according to the stage. Surgical resection, neoadjuvant chemoradiotherapy and adjuvant chemotherapy are the treatment options according to the staging of the disease at the time of first diagnosis. Positron Emission Tomography-Computed Tomography (PET-CT) is used in the indications of diagnosis, staging, restaging, detection of recurrence and evaluation of treatment response in colorectal cancers. In this review, the limitations of current imaging methods and the place of PET-CT imaging in colorectal cancer staging and its potential future uses will be explained.
