Abstract:
Objective: To assess the feasibility of applying the scoring system proposed by Sylvester RJ in predicting recurrence and progression of nonmuscle invasive bladder carcinoma (NIBC) after transurethral resection (TUR). Methods: Using Sylvester RJ's predicting system, we evaluated the risk factors for recurrence and progression of NIBC after TUR in patients treated in the Department of Urinary Surgery of Changhai Hospital in a ten-year period. The 1-year, 5-year recurrence rates and progression rates of patients with different scores were calculated and the results were compared with the results of Sylvester RJ system. Results: The data of 187 patients with NIBC treated in the Department of Urinary Surgery of Changhai Hospital from Jan. 1992 to Jan. 2002 were collected. The 1-year recurrence rates in 0 score group, 1-4 score group, 5-9 score group and 14-23 score group were 13.3%, 21.0%, 36.0% and 58.8%, respectively; their 1-year progression rates were 0, 1.4%, 5.1% and 15.6%, respectively. The 5-year recurrence rates were 26.5%, 44.0%, 59.5% and 82.4%, respectively; and their progression rates were 1.1%, 6.7%, 14.8%, and 53.1%, respectively. The above results were not significantly different from those of Sylvester RJ's (P>0.05). Conclusion: Sylvester RJ's system can be used for the patients in our hospital for predicting risk factors of recurrence and progression of NIBC after operation. Whether the system is suitable for all Chinese patient still need further study in greater population.
