Abstract: Objective: To assess the value of UroVysion FISH for screening urological malignancy and to explore its potential application in monitoring of recurrence of bladder cancer. Methods: Fresh urine specimens were collected from 368 cases with hematuria and/or history of urological cancer during follow-up. Diagnostic performance of UroVysion FISH for screening urological malignancy was evaluated in accordance with the results of pathology. Further analysis especially in patients with hematuria was conducted to determine the value of UroVysion FISH for detecting urological malignancy as well as for monitoring recurrence of bladder cancer. Results: ① The sensitivity of UroVysion FISH for detecting urological malignancy (bladder cancer, renal cancer, carcinoma of ureter, prostatic cancer) in patients with hematuria was superior to that without hematuria(P<0.005). ② Results of UroVysion Fish were closely related to tumor grade of urological malignancy. The sensitivity and specificity of UroVysion Fish for diagnosing high-stage tumor were higher than those of low-stage, especially in patients with hematuria. ③ A total of 45.51%(71/156) patients who eventually diagnosed as bladder cancer had cancer recurrence, and 57.75%(41/71) of them could be predicted according to the results of UroVysion Fish. ④ Results of FISH for bladder cancer follow-up in patients with hematuria showed higher sensitivity than in patients with history of urological malignancy. Conclusions: UroVysion FISH has high sensitivity and specificity for detecting urological malignancy, and the results are strongly relevant to tumor malignancy and invasion. UroVysion FISH is valuable for monitoring recurrence of bladder cancer, especially in patients with hematuria.
