目的:加深对囊性肾细胞癌的认知,提高囊性肾细胞癌的诊治水平。方法:回顾性分析2007～2011年收治的32例具有显著囊性特点的肾细胞癌患者的临床表现、影像学、病理学及治疗手段等临床资料。结果:囊性肾细胞癌无特征性临床表现,术前影像学检查可以提供诊断线索。28例为囊性变性肾细胞癌,4例为多房囊性肾细胞癌。21例行根治性肾切除术,10例行肾部分切除术,1例行患侧根治性肾切除及输尿管全长切除术。31例获得随访,平均随访期为18.0个月(4～49个月)。结论:囊性肾细胞癌是一类在影像学和大体病理上具有显著囊性改变的肾癌统称,临床上主要关注多房囊性肾细胞癌和囊性变性肾细胞癌两种亚型,两者在预后上存在巨大差异,应采取不同的治疗方式。
Objective: To deepen the cognition of cystic renal cell carcinoma and improve the diagnosis and treatment of cystic renal cell carcinoma. Methods: Clinical data of 32 patients with significant cystic features of renal cell carcinoma from 2007 to 2011 were retrospectively analyzed. The clinical data, imaging findings, pathology and treatment methods were retrospectively analyzed. Results: Cystic renal cell carcinoma has no characteristic clinical manifestations, preoperative imaging examination can provide diagnostic clues. 28 cases of cystic degenerative renal cell carcinoma, 4 cases of multilocular renal cell carcinoma. 21 cases underwent radical nephrectomy, 10 cases underwent partial nephrectomy, and 1 case underwent radical nephrectomy and total ureteral resection. Twenty-one patients were followed up for an average of 18.0 months (range 4-49 months). CONCLUSIONS: Cystic renal cell carcinoma is a group of renal cancers with significant cystic changes in both imaging and gross pathology. Clinically, there are two subtypes of multilocular cystic renal cell carcinoma and cystic degenerative renal cell carcinoma, There are huge differences in prognosis between the two, should take a different treatment.
