Durable complete response to combination nivolumab and ipilimumab in metastatic renal cell carcinoma

Immune checkpoint inhibitors, which promote or suppress the anti-tumor immune response, are becoming the mainstay of cancer treatment. In 2018, CheckMate 214 study showed a higher response rate with ipilimumab and nivolumab combination therapy compared to conventional therapy for advanced renal cell carcinoma. We report a case of complete response and durable response for two years to ipilimumab and nivolumab combination therapy in a patient with postoperative renal cancer recurrence that caused immune-related adverse events such as interstitial pneumonia and hepatotoxicity.
