Abstract

Immunotherapies now dominate the treatment landscape for melanoma, but why they only work in a subset of patients remains unclear. Here, the authors perform an immunogenomic analysis on 67 intratumor sub-regions of a PD-1 inhibitor resistant melanoma, and 2 additional metastases from a single patient, mapping the spatial relationships between genomic and immune heterogeneity at high resolution.
