Local Staging Characteristics (T2, T3) of Colorectal Cancer In Multislice Computerized Tomography (MSCT) Imaging

Abstract

Background: Early determination of the local staging of colorectal cancer is very important to determine the prognostic and optimal management of therapy. The purpose of this study was to determine the local staging characteristics (T2, T3) of colorectal cancer on MSCT imaging.Method: a descriptive design with a retrospective analytical observation approach, namely by evaluating the results of a local staging CT scan (T2, T3) of colorectal cancer. The sample size was 34 cases of colorectal cancer that met the inclusion criteria.Results: 8 cases (23.5%) of colorectal cancer were found with local T2 staging and 26 cases (76.5%) with local T3 staging. The characteristics of local staging T2 are the majority of 100% solid components, 100% clear boundaries, 100% homogeneous enhancement patterns, and 100% not invading surrounding organs. While the characteristics of the local staging of T3 are mostly solid components 61.53%, unclear boundaries 73.07%, irregular margins 96.15%, mass morphology 88.46%, homogeneous enhancement patterns 61.53% and heterogeneous 38.46%, does not invade the surrounding organs 100%. Conclusion:The differences in the characteristics of local T2 and T3 staging lie in the tumor boundaries, tumor shape, and patterns of enhancement.
