ABSTRACT
PURPOSE: To investigate the usefulness of urine cytology in the detection of tumor recurrence in terms of practicality and cost-effectiveness. MATERIALS AND METHODS: We retrospectively analyzed 393 patients who underwent transurethral resection of bladder tumor (TURBT) for non-muscle-invasive bladder cancer (NMIBC) from January 2010 to June 2013. All patients underwent cystoscopy, urine cytology, urinalysis, and computed tomography (CT) at 3 and 6 months after TURBT. In 62 cases, abnormal bladder lesions were identified on cystoscopy within 6 months. Suspicious lesions were confirmed pathologically by TURBT or biopsy. Patients were grouped by modalities: group I, urine cytology; group II, CT; group III, urinalysis; group IV, urine cytology plus CT; group V, urine cytology plus urinalysis; group VI, CT plus urinalysis; group VII, combination of all three modalities. Each group was compared by cost per cancer detected. RESULTS: Forty-nine patients were confirmed to have tumor recurrence and 13 patients were confirmed to have inflammation by pathology. The overall tumor recurrence rate was 12.5% (49/393) and recurrent cases were revealed as NMIBC. Sensitivity in group I (24.5%) was lower than in group II (55.1%, p=0.001) and group III (57.1%, p<0.001). However, in group VII (77.6%), the sensitivity was statistically similar to that of group VI (75.5%, p=0.872). Under the Korean insurance system, total cost per cancer detected for group VII was almost double that of group VI (p=0.041). CONCLUSIONS: Routine urine cytology may not be useful for follow-up of bladder cancer in terms of practicality and cost-effectiveness. Application of urine cytology needs to be adjusted according to each patient.
