目的 :提高囊性肾细胞癌的诊断和治疗水平。方法 :回顾分析了自 1986年 1月至 1996年 7月间 13例囊性肾细胞癌和同期 2 44例实质性肾细胞癌的临床资料。结果 :囊性肾细胞癌术前影像学检查的正确率为76.9% ,手术治疗的 5年生存率达 92 .3 % ,核分级和TNM分期较低 ,肿瘤细胞类型为透明细胞。结论 :囊性肾细胞癌是一种恶性度较低的肿瘤 ,应与肾细胞癌囊性坏死等肾囊性病变鉴别
Objective: To improve the diagnosis and treatment of cystic renal cell carcinoma. Methods: The clinical data of 13 cases of cystic renal cell carcinoma and 2 44 cases of substantial renal cell carcinoma from January 1986 to July 1996 were retrospectively analyzed. Results: The correct rate of preoperative imaging of cystic renal cell carcinoma was 76.9%. The 5-year survival rate of surgical treatment was 92.3%. The nuclear grade and TNM stage were lower. The tumor cell type was clear cell. CONCLUSIONS: Cystic renal cell carcinoma is a less malignant tumor that should be distinguished from nephrogenic cystic lesions such as cystic necrosis of renal cell carcinoma
