[A Case of Myocardial Metastasis of Renal Cell Cancer Treated with Nivolumab].

The patient a 48-year-old male, underwent nephrectomy for clear cell renal cell carcinoma. After surgery, the patient was treated sequentially with sunitinib, axitinib, and everolimus for multiple pulmonary metastases and iliopsoas muscle metastasis. After 16 months, subcutaneous metastasis and left ventricular myocardial metastasis developed without any symptoms. He was treated with pazopanib for these metastases. However, no shrinkage was seen and bone metastasis in right acetabulum appeared. After radiation therapy (20 Gy/5 Fr) for right acetabulum, nivolumab was administered for myocardial metastasis and subcutaneous metastasis. Significant shrinkage of metastases was seen after 3 courses of nivolumab and the patient's condition remained stable after 31 courses of nivolumab.
