ABSTRACT
Objective To Validate the prognostic significance of the European Organization for Research and Treatment of Cancer (EORTC) risk tables in Chinese patients with non-muscle invasive bladder cancer (NMIBC). Methods According to the scoring standard of the EORTC system, 225 NMIBC patients were reviewed and divided into 3 groups: low, intermediate and high risk groups for recurrence and progression respectively. The probabilities of recurrence and progression at 1 year and 5 year for each group were calculated using life-table analysis and then compared with the EORTC risk tables. Log-Rank test and multivariable analysis were used to analyze the possible differences between risk groups and to find independent prognostic factors. Results For low (n= 32, 25), intermediate (n=109, 128) and high (n=84, 72) risk groups, the probabilities of recurrence and progression at 1 year were 15. 1%, 31.2%, 55.5% and 0. 3%, 2. 0%, 15.5% respectively. The probabilities at 5 year were 28. 2%, 55.2%, 75.0% and 1.4%, 12.9%, 54. 7%. All the results were similar to that of EORTC tables except the probability of progression at 5 year for the high progression risk group.The differences between different risk groups were significant (P<0.01). In a multivariable analysis for recurrence and progression, the EORTC scores had independent significance (P<0.01). Conclusions EORTC risk tables could stratify NMIBC patients effectively according to the risk of recurrence and progression. It could be a useful tool for Chinese urologists.
