Tumor aneuploidy correlates with markers of immune evasion and with reduced response to immunotherapy

Abstract excerpt

Chromosomal chaos and tumor immunity Cancer immunotherapy produces durable clinical responses in only a subset of patients. Identification of tumor characteristics that correlate with responses could lead to predictive biomarkers and shed light on causal mechanisms. Davoli et al. found that human tumors with extensive aneuploidy—i.e., that display a highly abnormal number of chromosomes and chromosomal...
