目的 :比较CT肾癌分期和INSS病理分期的相关性并对影响CT对肾癌分期的影响因素进行探讨 ,总结影响肾癌分期的因素。方法 :运用CT和手术病理及细胞学检查 (INSS分期 )对 1993年 9月～ 2 0 0 2年 8月进行手术治疗的 10 6例肾癌患者进行分期。回顾性地分析本实验组的术前CT资料 ,探讨CT对肾癌诊断和分期的价值。结果 :经术后病理诊断证实 ,本组CT对肾癌的准确率为 91.5 %。按Robson分期标准 ,CT对肾癌各分期的准确率分别为Ⅰ期 :87.5 % ,Ⅱ期 :76 .5 % ,Ⅲa期 :75 % ,Ⅲb期 :6 2 .5 % ,ⅢC期 :70 .0 % ,Ⅳa期 :75 .0 % ,Ⅳb期 :10 0 .0 %。分期错误率为 18.7%。结论 :CT可作为肾癌临床诊断评估和术前分期的重要依据
Objective: To compare the correlation between the stage of renal cell carcinoma and the pathological stage of INSS, and to explore the influential factors of CT on the stage of renal cell carcinoma, and to summarize the factors affecting the stage of renal cell carcinoma. Methods: A total of 106 patients with renal cell carcinoma undergoing surgery from September 1993 to August 2002 were staged using CT, pathology and cytology (INSS staging). Retrospective analysis of the experimental group preoperative CT data to explore the value of CT on the diagnosis and staging of renal cell carcinoma. Results: The postoperative pathological diagnosis confirmed that the accuracy of this group of CT on renal cell carcinoma was 91.5%. According to the Robson staging criteria, the accuracy rates of CT for stage of renal cell carcinoma were stage Ⅰ: 87.5%, stage Ⅱ: 76.5%, stage Ⅲa: 75%, stage Ⅲb: 62.5%, and stage ⅢC: 70. 0%, IVa: 75.0%, IVb: 100.0%. Staging error rate was 18.7%. Conclusion: CT can be used as an important basis for clinical diagnosis of renal cell carcinoma and preoperative staging
