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 clinical, pathological and imaging features of multilocular cystic renal cell carcinoma (MCRCC) with other complicated nephrogenic lesions. Methods Sixty-four patients with pathologically confirmed complex renal cystic lesions from 2007 to 2011 in our hospital were enrolled. Among them, 17 were MCRCC, 28 were cystic renal cell carcinoma (CRCC), 19 were cystic benign lesions Cases, retrospective analysis of three groups of clinical data, pathology and CT features. Results (1) The cystic fluid properties of MCRCC group and benign lesion group were mainly serous (82.4% and 52.6%, respectively), and cysts of CRCC were mainly turbid necrosis (64.3%). The clinical stage of MCRCC was significantly lower than that of MCRCC CRCC group (P = 0.001). (2) The main distribution of MCRCC and nephropathy was Bosniak Ⅲ grade (64.7%: 57.9%), and CRCC mainly in Bosniak Ⅳ grade (67.8%). The median CT value of cyst fluid in CRCC group was significantly higher than that in MCRCC group and benign cystic lesion group (30.6:15.8:10.6, P = 0.019). There was a significant difference in soft tissue shadow size between MCRCC and CRCC lesions (P = 0.000). Conclusion MCRCC has a lower degree of malignancy than CRCC in clinical, pathological and imaging aspects, and has some similarities with cystic benign lesions in some aspects.
