摘要目的 验证欧洲癌症研究与治疗组织(European Organization for Research and Treatment of Cancer,EORTC)膀胱癌预后风险评分表对我国非肌层浸润性膀胱癌(non-muscle invasive bladder cancer,NMIBC)患者预后判断的准确性.方法 按照EORTC评分标准对225例NMIBC患者进行评分并按得分高低分组,寿命表法计算每组患者的1年和5年实际复发率及进展率,Log-Rank检验行组间比较并与EORTC评分表相应结果对比.多因素分析筛选影响NMIBC预后的独立因素.结果 低、中、高复发风险者分别32、109、84例,低、中、高进展风险者分别25、128、72例.低、中、高复发及进展风险组术后1年复发率和进展率分别为15.1%、31.2%、55.5%和0.3%、2.0%、15.5%;术后5年复发率和进展率分别为28.2%、55.2%、75.0%和1.4%、12.9%、54.7%.除高进展风险组5年进展率略高外,其余均接近EORTC评分表.各组间相比,复发率及进展率的差异有统计学意义(P＜0.01).多因素分析表明,EORTC评分为影响NMIBC患者术后复发及进展风险的独立因素(P＜0.01).结论 EORTC风险评估表使用简便,可以按照复发及进展风险概率将患者准确分层,值得推广应用.

abstractsObjective 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.
