(P60) Targeting Radiation Therapy to Soft Tissue Lesions Prior to the Start of Immunotherapy Improves Survival in Extracranial Metastatic Melanoma

Preclinical studies have reported that radiation therapy (RT) enhances antitumor immune response and can act synergistically when administered with immunotherapy. We aim to explore the clinical effect of combining RT and immunotherapy in extracranial metastatic melanoma. We also report the impact of timing of RT relative to the start of immunotherapy and its impact on clinical outcomes.
