摘要
目的比较多房囊性肾癌(multilocular cystic renal cell carcinoma,MCRCC)与其他复杂性肾囊性病变在临床、病理及影像学方面的不同特点。方法搜集本院2007年至2011年经手术病理证实的复杂性肾囊性病变64例,包括MCRCC患者17例,囊性肾癌(cystic renal cell carcinoma,CRCC)28例,肾脏囊性良性病变19例,回顾性分析三组病例的临床资料、病理及CT特征。结果 (1)MCRCC组与良性病变组囊液性状均以浆液状为主(分别为82.4%,52.6%),CRCC囊液以浑浊坏死为主(64.3%);MCRCC组临床T分期明显低于CRCC组(P=0.001);(2)MCRCC与肾良性病变主要分布在BosniakⅢ级(64.7%∶57.9%),CRCC主要分布在BosniakⅣ级(67.8%)。CRCC组囊液CT值中位数明显高于MCRCC与良性囊性病变组(30.6∶15.8∶10.6,P=0.019)。MCRCC与CRCC病灶内软组织影大小存在明显差异(P=0.000)。结论 MCRCC在临床、病理及影像学方面均显示其恶性程度低于CRCC,甚至在某些方面与肾脏囊性良性病变有相似的特点。
Objective To compare the clinicopathological and imaging features of multilocular cystic renal cell carcino- ma（MCRCC） with other complex renal cystic lesions. Methods The clinical, pathological and CT findings of 64 cases with complex renal cystic lesions （Bosniak Ⅱ F, Ⅲand Ⅳ ） were retrospectively analyzed. Of the 64 cases, 17 were classi- fied as MCRCC and 19, 28 were classified as benign cystic lesion and cystic renal cell carcinoma （CRCC）, respectively. Results （ 1 ） The pathological results showed that both MCRCC and other benign cystic lesions contained high proportion of serous fluid （52.6%, 82.4%, respectively）, but CRCC had more necrotic liquid （64.3%）, （P = 0. 003）. The Tumor stage of patients with MCRCC was lower than that patient with CRCC（ P = 0.001 ）. （2） Both MCRCC and other benign cystic lesions were significantly more than CRCC to be of Bosiniak Ⅲ （57.9%： 64.7%： 17.8% , P = 0.033）. The median CT value of cystic component in CRCC was higher than that in MCRCC and other benign cystic lesions（ 30.6： 15.8：10.6 ,P = 0.019）, The size of soft tissue in the lesion was significantly different between MCRCC and CRCC （P = 0.000）. Conclusion MCRCC has lower malignant potential compared with CRCC and even somehow similar with the be- nign cystic lesions on clinicopathological and imaging features.
