Renal cell carcinoma with multiple bone metastases effectively treated by a combination of tyrosine kinase inhibitor, robot-assisted partial nephrectomy, and metastasectomy

Recent advances in medications, such as immune checkpoint inhibitors (ICIs) and tyrosine kinase inhibitors (TKIs), have improved metastatic renal cell carcinoma (mRCC) outcomes. We report a case of mRCC with bone metastasis that was successfully treated using a multidisciplinary approach. Here, we present a case of a 56-year-old man with left renal cancer and large and painful bone metastases at the 11th thoracic vertebrae (Th11). Therefore, a metastasectomy of Th11 was performed. Systemic treatment with TKI, robot-assisted partial nephrectomy, and metastasectomy were then administered. No recurrence was observed in >2 years. Long-term disease-free survival with the TKI-era multidisciplinary approach in a patient with mRCC remains significant when considering treatment sequences, especially now that drug treatment options-including ICIs-have increased. Treatment strategy and indication and timing of resection of the primary lesion and metastasectomy should be carefully considered in each case.
