CYTOLOGIC DETECTION OF URINARY-BLADDER INVOLVEMENT IN CERVICAL-CANCER

One-hundred and four patients with advanced carcinoma of the cervix ha d their urine specimens collected, at the time of cystoscopy, for cyto logic detection of the presence of malignant cells. Forty-eight (46%) of the patients had evidence of bladder mucosal involvement at cystosc opy. The overall sensitivity of urine cytology in detecting bladder mu cosal involvement was 56%, with a specificity of 93%. The predictive v alue for a positive result was 87% and the accuracy of the test was 76 %. The findings indicate that urine cytology is a useful test for dete cting bladder mucosal involvement in cervical cancer where cystoscopy is not available.
