Immunotherapy plus other drug classes: encouraging results in mCRC
In the setting of microsatellite-stable (MSS) metastatic colorectal cancer (mCRC), combining immune checkpoint inhibitors (ICIs) with targeted drugs is a potential approach to augment the immune response and increase immunogenicity [1]. For example, vascular endothelial growth factor receptor (VEGFR) inhibitors in addition to ICIs have shown promising activity in patients with pretreated mCRC [2-5].
