多囊性肾细胞癌18例诊疗分析

Analysis of diagnosis and treatment of multilocular cystic renal cell carcinoma： a study of eighteen cases

目的探讨多囊性肾细胞癌的诊断、鉴别诊断、治疗与预后。方法1999年1月至2010年10月，共收治398例肾癌患者，其中多囊性肾细胞癌18例，回顾并总结其临床诊治资料。结果多囊性肾细胞癌占同期肾癌病例的4．52％（18／398）；肿瘤TNM分期：pT。NoMo期肿瘤5例，oT2NoMo期肿瘤13例；G1级肿瘤8例，G2级肿瘤10例。结论多囊性肾细胞癌术前鉴别诊断难度大，诊断主要依据CT，尤其是螺旋CT检查，治疗上应以根治性肾切除术为主，部分病例可行保留。肾单位手术。

Objective To investigate the diagnosis,differential diagnosis, treatment and prognosis of muhilocular cystic renal cell carcinoma （MCRCC）. Methods A total of 398 patients with renal carcinoma were hospitalized from January 1999 to October 2010,and there were 18 patients with MCRCC. The data of clinical diagnosis and treatment of these cases were analyzed retrospectively. Results MCRCC accounted for renal carcinoma in the same period was 4.52%（18/398）. According to TNM staging, 5 cases were in stage pT,NoMo, 13 cases in stage pT2NoM0. There were 8 cases in GI phase, 10 cases in G2 phase. Conclusions The preoperative diagnosis of MCRCC is difficult to differentiate, and mainly based on CT, especially spiral CT. It should be treated mainly with radical nephrectomy, and nephron sparing surgery in some cases.
