In this issue of Cancer Cell , Woolston et al. show that colorectal cancers that become refractory to initially effective anti-EGFR therapy contain an abundance of stromal and immune cells, irrespective of the contextual presence of resistance-conferring mutations. This reconfiguration puts forward therapeutic opportunities for patients who relapse on EGFR-targeting treatment.
