Renal cell carcinoma (RCC) is the most common type of kidney cancer, accounting for most renal cancers. Oligoprogressive RCC (OP-RCC) describes metastatic RCC wherein one or a few metastatic sites continue to progress, while the majority of metastatic sites are stable on systemic therapy. Treatment options for the primary site for OP-RCC include cytoreductive nephrectomy, stereotactic body radiation therapy (SBRT), or ablative techniques, although there is no currently agreed-upon standard for treatment. This report describes a 76-year-old male with OP-RCC who was treated with salvage SBRT after failing cytoablation therapy. A review of the current literature on SBRT as a treatment option for OP-RCC is presented and discussed. This case demonstrates that SBRT may be a viable salvage treatment option for patients with OP-RCC that provides good local disease control while preserving long-term renal function.
