[Four Cases of Liver Resection for Liver Metastases from Renal Cell Carcinoma].

ABSTRACT

We report 4 cases of liver metastasis from renal cell carcinoma(RCC). Case 1 72 years old, female. Pancreatic metastasis was resected 7 years after resection of left RCC, and hepatic posterior sectionectomy was performed for multiple liver metastases 2 years later. After that, multi-organ metastasis appeared and she died of the primary disease. Case 2 72 years old, male. Liver metastasis and right RCC appeared 16 years after resection of left RCC, and hepatic posterior sectionectomy and partial resection of right kidney were performed. Nine months later, liver metastasis recurred and hepatic partial resection was performed. Case 3 55 years old, male. After surgery for right RCC with tumor thrombus in the right atrium, multiple lung and liver metastases appeared, and hepatic central bisectionectomy was performed after chemotherapy. Case 4 60 years old, male. Multiple pancreatic and lung metastases appeared 10 years after resection of left RCC, and most of them shrank or disappeared with chemotherapy. But increasing metastases appeared in the tail of pancreas and the right lobe of liver 16 months later, and hepatic subsegmentectomy and distal pancreatectomy were performed. Multidisciplinary treatment such as aggressive chemotherapy and excision is expected to improve the prognosis for liver metastasis from RCC.
