摘要目的 评价欧洲癌症研究与治疗组织风险评分表(European Organization for Research and Treatment of Cancer risk tables,EORTC风险评分表)用于非肌层浸润性膀胱尿路上皮癌患者预后评估的可行性.方法 回顾性分析2003年1月至2009年2月收治的185例非肌层浸润性膀胱尿路上皮癌患者临床资料,其中Ta128例、T1 57例;G1 87例、G253例、G345例;肿瘤数目为单发、2～7个、≥8个者分别120、36、29例;肿瘤直径＜3 cm者131例、≥3 cm者54例;伴发原位癌者6例.185例均行经尿道膀胱肿瘤电切术,术后均行常规膀胱灌注化疗.采用电话随访方式,随访6～77个月,平均36个月.应用EORTC风险评分表进行预后风险评分,计算各评分组患者的1年复发率和进展率,并与EORTC评分表的预计值进行比较.结果 185例中1年内复发48例(25.9%),1年内出现肿瘤进展者7例(3.8%).根据患者实际情况计算,0、1～4、5～9、10～17分4组患者1年实际复发率分别为10.4%(5/48)、21.5%(14/65)、35.2%(19/54)、55.6%(10/18);0、2～6、7～13、14～23分患者1年实际进展率分别为0(0/43)、1.5%(1/67)、6.7%(4/60)、13.3%(2/15).经x2检验,结果与评分表的预计值差异无统计学意义(P＞0.05);而低危、中危、高危3组患者1年复发率及进展率差异有统计学意义(P＜0.05).结论 EORTC风险评分表可用于非肌层浸润性膀胱尿路上皮癌术后复发和进展风险的短期预测,对长期预测的应用及广泛人群的适用性尚待进一步验证.

abstractsObjective To evaluate the feasibility of European Organization for Research and Treatment of Cancer (EORTC) risk tables in non-muscle invasive bladder cancer in Chinese patients.Methods A retrospective analysis was performed on the data from 185 patients with non-muscle invaaive urothelial bladder cancer from January 2003 to February 2009. Among the 185 patients, 128 patients were stage Ta compared with 57 patients who were stage T1. There were 87, 53 and 45 patients with grade G1, G2 and G3 respectively. Transurethral resection of the bladder tumor was performed on all the patients and all the patients received routine post-operative intravesical instillation. A telephone interview follow-up was conducted on all the patients, and the average follow-up period was 36 months. EORTC risk tables were used to calculate risk scores for recurrence and progression for each patient. The recurrence and progression rates of different risk groups were recorded and compared with the estimated rates by EORTC risk table. Statistical analysis was used for comparison. ResultsTotal 1-year recurrence rate and progression rate for these patients were 25.9% and 3.8% respectively. According to calculated values of the patients, the 1-year recurrence rates of Group 0, Group 1-4, Group 5-9, Group 10-17 were 10.4%(5/48), 21. 5%(14/65), 35. 2% (19/54), 55.6%(10/18), respectively. The 1-year progression rates of Group 0, Group 2-6, Group 7-13, Group 14-23 were 0% (0/43), 1.5% (1/67), 6. 7% (4/60), 13. 3% (2/15). There was no significant difference between the real rates and estimated rates of the EORTC risk tables (P＞0. 05). However,the 1-year recurrence and progression rates between the low risk group, the medium risk group and the high risk group showed significant differences respectively (P ＜ 0. 05 ). Conclusions The EORTC risk tables are feasible to evaluate the recurrence and progression risk of non-muscle invasive bladder cancer in the present cohort. Nevertheless, the long term value and feasibility need more research to confirm.
