S1801: Pembrolizumab in Treating Patients With Stage III-IV High-Risk Melanoma Before and After Surgery (H-44987)
S1801: A Phase II Randomized Study of Adjuvant Versus NeoAdjuvant MK-3475 (Pembrolizumab) for Clinically Detectable Stage III-IV High-Risk Melanoma
This phase II trial studies how pembrolizumab works before and after surgery in treating patients with stage III-IV high-risk melanoma. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving pembrolizumab before and after surgery may work better in treating melanoma.
