Immunotherapy, page-4

Phase 2 trial results presented at ASCO showed responses to anti–PD-1 antibody pembrolizumab (Keytruda) in about 60% of colorectal cancers with MMR deficiency, but no responses in CRC lacking this feature. Link is below for those interested. Exciting result for that small subset of patients, which is only 4% of metastatic CRC. SIRT unlikely to be replaced by this expensive new therapy, I don't see why they couldn't be used together in the MMR deficient group.
