摘　　要：目的探讨并评估多房囊性肾细胞癌(MCRCC)的诊断及治疗方法的选择。方法回顾性分析8例MCRCC的临床资料。分析MCRCC的临床表现、放射学特征、手术方法及病理特征和随访结果。结果 MCRCC占全部含囊性成分的肾细胞癌的3.3%,75.0%的病例行根治性肾脏切除,25.0%行肾部分切除。肿瘤的平均直径是3.7 cm,平均实体成分占肿瘤的9.5%,平均肿瘤分级是1.1。平均随访38.2个月,无一例复发或转移。结论 MCRCC专指那些囊壁上由小量(25.0%或更少)的透明癌细胞构成的囊性肾细胞癌,是肾细胞癌的一种罕见的亚型,容易与其他表现的肾囊性病变的疾病相混淆,鉴别诊断很重要,超声检查是一个首选的方法,计算机断层扫描能更好地识别其恶性特征。磁共振成像用于模棱两可的病例。本病的良性生物学行为可能使患者受益于保留肾单位的手术。Objective To assess the diagnosis and treatment of multilocular cystic renal cell carcinoma（MCRCC）.Methods The clinical data of 8 cases of MCRCC were analyzed retrospectively.The clinical features,radiologic features,surgical procedure,pathologic features,and follow-up outcomes of the MCRCC were studied.Results Of all the RCC,8 cases（3.3%） of MCRCC were observed.For treatment,radical nephrectomy was done in 75.0% and partial nephrectomy in 25.0%.The mean tumor size was 3.7 cm.The mean solid component of the tumor was 9.5%.They were followed up for an average of 38.2 months.None of the 8 cases available for follow-up showed any evidence of recurrence.Conclusion MCRCC is an uncommon subtype of RCC.It is easily confused with other variety of cystic disorders,so the identification is very important,ultrasonography is found to be a useful screening test,but computed tomography is the imaging study of choice to identify malignant features.The benign clinical course of these lesions suggests that patients may benefit from nephron-sparing surgery.
