A 78-year-old woman underwent partial hepatectomy for the treatment of hepatocellular carcinoma(HCC).After surgery, she was further treated with radiofrequency ablation(RFA)and transcatheter arterial embolization(TAE)for the intrahepatic reccurence of HCC.Thirty months after surgery, her tumor marker levels increased and computed tomography (CT)revealed an intrahepatic mass and right renal tumor which extended into the renal vein.We therefore suspected a reccurence of HCC and right renal cell carcinoma which extended into the renal vein, and thus performed right nephrectomy before again performing TAE to treat the reccurence of HCC.The pathological findings showed HCC metastasis in the kidney. Nephrectomy should be performed as soon as possible in patients with a renal vein tumor thrombus in order to prevent the occurrence of a pulmonary embolism.We herein describe a very rare oncologic emergency case and review the relevant literature.
一名78岁女性因肝细胞癌（HCC）接受了部分肝切除术。术后，她因HCC肝内复发接受了射频消融（RFA）和经导管动脉栓塞（TAE）治疗。术后30个月，她的肿瘤标志物水平升高，计算机断层扫描（CT）显示肝内有肿块以及延伸至肾静脉的右肾肿瘤。因此，我们怀疑是HCC复发以及延伸至肾静脉的右肾细胞癌，于是在再次进行TAE治疗HCC复发之前先进行了右肾切除术。病理结果显示为肾脏的HCC转移。对于存在肾静脉肿瘤血栓的患者，应尽快进行肾切除术以预防肺栓塞的发生。我们在此描述了一例非常罕见的肿瘤急症病例并回顾了相关文献。
