摘　　要：目的:探讨减瘤手术联合靶向治疗转移性肾癌(metastatic renal cell carcinoma,mRCC)合并下腔静脉癌栓患者的安全性和有效性。方法:回顾性分析2011年11月至2019年02月收治的13例mRCC合并下腔静脉癌栓患者的临床资料,根据有无靶向治疗分为靶向组和非靶向组。靶向组8例,男7例,女1例,平均年龄(48.38±13.92)岁,肿瘤位于左侧5例,右侧3例,平均直径(9.93±5.37)cm。非靶向组5例,男4例,女1例,平均年龄(60.60±5.37)岁,肿瘤位于左侧1例,右侧4例,平均直径(11.24±2.76)cm。结果:术后病理:靶向组透明细胞癌6例,乳头状肾细胞癌和肉瘤样癌各1例,术后TNM分期T_(3b)N_(1)M_(0)和T_(4)N_(1)M_(1)各1例,T_(3a)N_(1)M_(1)3例,T_(3b)N_(1)M_(1)3例。非靶向组透明细胞癌2例,Xp11.2易位/TFE3基因融合相关性肾癌、乳头状肾细胞癌和低分化癌各1例,术后TNM分期T_(3b)N_(1)M_(1)和T_(3c)N_(1)M_(1)各1例,T_(4)N_(1)M_(1)3例。所有患者获随访4~47个月,中位随访时间27个月。靶向组和非靶向组中位无进展生存期分别为6.5个月和2个月,半年、1年无进展生存率分别为50.00%(4/8)、37.50%(3/8)和40.00%(2/5)、20.00%(1/5),两组对比无统计学差异(HR=0.46,95%CI:0.13~1.70,P=0.1259)。靶向组和非靶向组中位总生存期分别为41个月和8个月,1年和2年总存活率分别为100.00%(8/8)、87.50%(7/8)和20.00%(1/5)、20.00%(1/5),两组对比统计学差异显著(HR=0.17,95%CI:0.03~0.99,P=0.0005)。结论:减瘤手术治疗mRCC并下腔静脉癌栓患者安全有效,术后进行靶向治疗可显著延长患者总生存期。Objective:To investigate the efficacy and safety of cytoreductive nephrectomy combined with targeted therapy for metastatic renal cell carcinoma(mRCC)with inferior vena cava(IVC)tumor thrombus.Methods:The clinical data of 13 mRCC patients with IVC tumor thrombus from November 2011 to February 2019 in our hospital were analyzed retrospectively.In the target group,there were 8 cases,7 males and 1 female,with an average age of(48.38±13.92)years old.Five tumors were on the left side and three tumors were on the right side,with an average diameter of(9.93±5.37)cm.In the non-targeted group,there were 5 cases,4 males and 1 female,with an average age of(60.60±5.37)years old.The tumor was located in 1 case on the left and 4 cases on the right,with an average diameter of(11.24±2.76)cm.Results:Postoperative pathology:In the targeted group,there were 6 cases of clear cell carcinoma,1 case of papillary renal cell carcinoma and 1 case of sarcomatoid carcinoma,1 case of T_(3b)N_(1)M_(0) and T_(4)N_(1)M_(1) respectively,3 cases of T_(3a)N_(1)M_(1) and T_(3b) N_(1)M_(1 )respectively.In the non-targeted group,there were 2 cases of clear cell carcinoma,1 case of Xp11.2 translocation/TFE3 gene fusion related renal carcinoma,papillary renal cell carcinoma and poorly differentiated carcinoma respectively,1 case of T_(3b)N_(1)M_(1) and T_(3c) N_(1)M_(1) respectively,and 3 cases of T_(4)N_(1)M_(1).All patients were followed up for 4~47 months,with a median follow-up of 27 months.The median progression free survival(PFS)time was 6.5 months and 2 months in the target group and non-target group,and the half-year and one-year PFS rates were 50.00%(4/8),37.50%(3/8)and 40.00%(2/5),20.00%(1/5),respectively.There was no significant difference between the two groups(HR=0.46,95%CI:0.13~1.70,P=0.1259).The median overall survival(OS)time of the target group and the non-target group was 41 months and 8 months respectively,and the 1-year and 2-year OS rates were 100.00%(8/8),87.50%(7/8)and 20.00%(1/5),20.00%(1/5),respectively.The difference was s
