Article Abstract

Hyperprogression is a paradoxical cancer acceleration observed in a minority of patients upon immunotherapy. In this issue of Cancer Cell, Li et al demonstrate that hyperprogressive tumors upregulate the Wnt/β-catenin pathway. This activation was subsequent to an oncogenic FGF2-mediated autocrine loop generated by the IFNγ released by CD8 T cells upon PD-1/PD-L1 blockade.
