Immunotherapy agents have significantly changed the landscape of melanoma treatment over the past decade. Paradigm shifts in treatment require reanalysis of the treatment algorithms in melanoma. Despite surgical excision, certain high risk patients with desmoplastic melanoma remain at high risk for local recurrence and retrospective data suggests improvement in local control with adjuvant radiation therapy. Likewise, despite surgical excision and effective systemic therapy agents, patients with extracapsular extension and other high risk features are at substantial risk of nodal basin (regional) recurrence. Adjuvant radiation therapy has been demonstrated to reduce the local recurrence risk. Despite these benefits, adjuvant radiation therapy in melanoma remains controversial in part because its use has not been definitively demonstrated to improve overall or disease-free survival in a randomized prospective study.
