Sequential therapy with nivolumab followed by ipilimumab induces complete response in metastatic melanoma of the lung but with severe hepatotoxicities

Since nivolumab significantly prolongs survival in patients with metastatic melanoma, the number of patients administered nivolumab is increasing, but only 30-40% of patients who received nivolumab monotherapy experienced objective tumor regression. Therefore, enhancing its anti-tumor immune response is of great interest to dermato-oncologists. In this report, we present a case of multiple metastatic melanomas in the lung successfully treated with nivolumab (2 mg/kg every 3 weeks for 12 weeks) followed by ipilimumab (3 mg/kg every 3 weeks for 9 weeks), but with severe liver dysfunction.
