BACKGROUND _ OBJECTIVES: Staging of @entity2622 is done clinically using International Federation of Obstetrics and Gynecology (FIGO) guidelines. It is based on physical examination findings and also includes results of biopsy, endoscopy and conventional radiological tests like chest radiograph, intravenous urography and barium enema. These conventional radiological investigations have largely been replaced by computed tomography (CT) and magnetic resonance imaging (MRI) at present. FIGO staging system does not consider CT and MRI mandatory; however, use of these modalities are encouraged. This prospective study was conducted to determine the role of CT in staging work up in @entity1 diagnosed with @entity2622 . METHODS: Fifty three @entity1 diagnosed with @entity2622 were evaluated with contrast enhanced CT scan of abdomen and pelvis. CT scan images were especially evaluated to determine @entity5 size, invasion of parmetrium, pelvic walls, rectum, urinary bladder and ureters, pelvic or @entity3329 and distant metastases. CT findings were associated with clinical findings and staging, including findings from cystoscopy and sigmoidoscopy. RESULTS: There was a poor agreement between clinical and @entity5 . Primary @entity5 was demonstrated on CT in 36 (70%) of 53 @entity1 . CT underestimated the parametrial, vaginal and pelvic wall invasion when compared with physical examination. CT overestimated the urinary bladder and rectal invasion when compared with cysto-sigmoidoscopy, however, CT had 100 per cent negative predictive value (NPV) to exclude @entity1494 . CT detection of lymph node enlargement and lung metastases influenced the management. INTERPRETATION _ CONCLUSIONS: Our findings show that CT scan does not reliably correlate with clinical FIGO staging of cervical @entity5 . However, it can detect urinary obstruction as well as nodal or distant metastases and thus improves the clinical FIGO staging.
