The median PFS was 54.1 months with nivolumab/ipilimumab vs 5.9 months with chemotherapy in patients with MSI-H/dMMR CRC.

Anlotinib/chemotherapy showed comparable efficacy vs bevacizumab/chemotherapy in patients with RAS/BRAF wild-type metastatic colorectal cancer.

Updated findings from BREAKWATER support encorafenib plus cetuximab and chemotherapy as a new standard of care in BRAF V600E-mutated metastatic CRC.

Among patients with rectal cancer who underwent total mesorectal excision following SCRT plus camrelizumab and chemotherapy, the 3-year OS rate was 93.3%.

For patients with right-sided CRC tumors, no significant progression-free survival difference was observed between the cetuximab and FOLFIRI-only groups.
