Tumor Neoantigens: When Too Much of a Good Thing Is Bad

Immunotherapy has been the most effective in tumors with high mutational burden. However, a recent study in Cell by Wolf et al. demonstrates that high intratumor heterogeneity (ITH) for cancer neoantigens paradoxically attenuates anti-tumor immune responses, suggesting a need to quantify ITH to improve patient selection for checkpoint blockade therapy.
