Clinical value of computerized tomography (CT) in assessment of recurrent uterine cancers

Fifty-one patients with a clinically suspected relapse of uterine cancer were evaluated with computerized tomography (CT) in the Departments of Obstetrics/Gynecology and Radiology of the University of Pavia. The accuracy of these scans was always compared with biopsy results (31 cases) or clinical outcome (20 cases). To evaluate the role CT played in the treatment of each patient we divided the results of these examinations into "Confirmative" (when there was clinical evidence of a tumor) and "Diagnostic" (when physical examination and conventional radiologic techniques were inconclusive). Overall diagnostic accuracy was 92%, specificity 80%, and sensitivity 92%. The authors found that CT provides information that is useful for planning treatment and for avoiding unnecessary surgical exploration when a tumor is clinically evident; furthermore, CT was found to be better than conventional diagnostic means in doubtful cases, especially those in which post-therapeutic pelvic fibrosis was not extensive (correct diagnosis is 15 of 19 cases).
