Melanoma Now One of the Most Curable Solid Cancers

MedStar Georgetown University Hospital’s Lombardi Comprehensive Cancer Center Offers Full Range of Latest Clinical and Research Approaches to Patient Care

MedStar Georgetown University Hospital’s Lombardi Comprehensive Cancer Center is now curing patients with high-risk and distant metastatic melanoma with FDA-approved and research immunotherapy treatments. Now the standard of care and the backbone for new research studies,  these immunotherapies work by restoring the function of tumor specific immune cells inside the tumor, enabling the immune system to fight the cancer on its own.These approaches are not chemotherapy and therefore do not have the side effects  traditionally associated with  chemotherapy. Instead, side effects are all related to activation of the immune system and can be addressed without altering the effectiveness of the immunotherapy.
