Abstract
The overall survival of melanoma patients has improved using antibodies targeting immune checkpoints (anti-PD-1, anti-CTLA-4 and anti-LAG-3). Systemic chemotherapy was administered in melanoma for many years with limited effectiveness. Here we report a case of a patient who experienced immune-mediated adverse effects from checkpoint blockade therapy and subsequently responded to chemotherapy. The patient presented with melanoma and paraneoplastic digital ischemia. She received a combination of ipilimumab/nivolumab and experienced G3 myocarditis, followed by melanoma progression after a steroid taper. This patient achieved a partial and durable response with platinum and taxane-based chemotherapy. This report suggests the possibility of a subset of patients who experience progression after immune-based side effects where chemotherapy may be effective in the modern age of melanoma treatment.
Plain language summary
We describe a patient with a type of skin cancer called melanoma. At first, we tried to treat it with a medication that made the patient's body's defense system fight against it, but it caused problems with her heart so we had to stop it. Instead, we used another type of treatment called chemotherapy, which worked. The patient remains off therapy 4.5 years later. The lesson learned from this case is that chemotherapy is still helpful in certain situations. The initial treatment did not stop the melanoma growth. In addition, the patient had life-threatening toxicity.
Tweetable abstract
Chemotherapy may be useful for melanoma patients intolerant to checkpoint blockade therapy. Written informed consent was obtained from the patient to publish a case report.
