Abstract

Background: Computed Tomographyhas an important role in bladder cancer staging and clinical treatment decisions. Objective: To determine the value of Computed Tomography in the assessment of bladder cancer tumor stage compared with the pathological results. Methods: A descriptive cross-sectional retrospective study on 95 patients with bladder cancer who underwent CT scans by the preoperative technique and obtained pathological results. Blind reading of T stage results on CT scan according to the TNM classification of AJCC 8th edition.Compare with pathological results, calculate sensitivity, specificity, accuracy, and positive predictive value for the role of each invasive stage of CT scan. Results: CT has a high value in diagnosing the T-stage of esophageal cancer.The value of CT in diagnosing ≥T3b stage has sensitivity, specificity, accuracy, and positive predictive value of 81.8%, 93.2%, 90.5%, and 78.3%, respectively. Stage T4 sensitivity, specificity, accuracy, positive predictive value were 85.7%, 98.8%, 97.9%, 85.7%, respectively. Conclusion: Computed Tomography enables accurate staging of bladder cancer, particularly from stage T3b and beyond.
