Abstract
- A retrospective analysis was done on 68 patients with primary superficial bladder cancer between September 1989 and December 1995. We evaluated the predictive value of urine cytology in the recurrence and the progression of superficial bladder cancer. Positive cytology was shown in 52.9% (36/68) and was significantly associated with tumor grade (p=0.001). The recurrence rate in patients with negative cytology was 28.1% (9/32) compared to 77.8% (28/36) in those with positive cytology (p=0;001). No patients of negative cytology had tumor progression while 4 out of 36 (11.1%) patients of positive cytology had progression to invasive or metastatic disease. In conclusion, urinary cytology appears to be a significant prognostic factor in superficial bladder cancer.
