ABSTRACT
OBJECTIVE:
To determine the clinical utility of cystoscopy to rule out bladder invasion in cervical cancer patients who have had pelvic computed tomographic (CT) scan.METHODS:
We reviewed charts of 49 patients at Walter Reed and Tripler Army Medical Centers who had International Federation of Gynecology and Obstetrics stage II or greater cervical cancer and who underwent both cystoscopy and CT scan before treatment. Data retrieved included diagnosis, race, age, cystoscopy results, and CT scan reports. These patients were evaluated and treated between January 1, 1991, and September 1997.RESULTS:
The mean age of the patients was 50 years. Seven of the women were Asian, five black, six white, one Hispanic, and 30 Pacific Islander. There were 40 squamous cell carcinomas and nine adenocarcinomas. There were 25 stage II, 20 stage III, three stage IV, and one recurrent stage II carcinomas. Three patients with bladder invasion were identified by cystoscopy and all also were identified with possible bladder invasion by CT scan. Two additional cases of possible invasion seen on CT scan proved not to be invasion with cystoscopy. The positive predictive valve of CT scan in predicting bladder invasion was 60% (three of five). The negative predictive valve of CT scan in predicting bladder invasion was 100%.CONCLUSION:
The utility of performing cystoscopy to rule out bladder invasion in a patient with no evidence of bladder involvement on CT scan is low and might not be necessary.
