Abstract

Objective: To study the reliability of CT scan interpretation in pre- and post-operative chemoradiation of rectosigmoid cancer.
Methods: Retrospective review CT scan of 12 patients with diagnosis of rectosigmoid cancer stage 3 or more in pre and post operative chemoradiation were done by 2 radiologists. Data analysis included maximum wall thickness, distance of lesion above anal verge, perirectal involvement, regional node, distant metastasis. Chest radiograph (CXR), endorectal ultrasound (ERUS), barium enema (BE), colonoscopy and treatment information were reviewed.
Results: Reliability of TNM staging by CT scan interpretation were .66, .50 and .75, respectively total reliability is .75 and overall validation of CT scan staging is .40 with statistic significant at .05 reference with pathological staging.
Conclusion: There was CT scan interpretation reliability in pre- and post- chemoradiation for rectosigmoid cancer patients.
