Body composition is prognostic and predictive of ipilimumab activity in metastatic melanoma

Abstract

Low SMD and receiving >2.03 mg/cm² are prognostic of poorer melanoma outcomes post ipilimumab. SMD may identify patients with flawed immunology and predict who may better respond to such therapy. Ipilimumab dosing by skeletal muscle index stands in contrast to weight-based dosing and may demonstrate a more accurate method of antibody dosing.
