Colon Cancer

For advanced stages of colorectal cancer, particularly stage IV or metastatic cases, genotyping for specific biomarkers such as RAS, BRAFV600, MSI/MMR, and HER2 is crucial. Therapy options vary based on these genetic profiles, with targeted treatments available for different mutations.

last line agents

Regorafenib trifluridine - tipiracil

STAGE IV/Metastatic - all metastatic colorectal cancers should be geonotyped for RAS, BRAFV600, MSI/ MMR, HER2

5FU/LV capecitabine + bevacizumab cetuximab/panitumumab for KRAS WT, left side tumor nivolumab/pembrolizumab for dMMR/MSI-h only nivolumab + ipilmumab for dMMR/MSI-H only trastuzumab + (pertuzumab or lapatinib) or fam-trastuzumab deruxtecan for HER2+, RAS, BRAF WTG
If improved functional status -> use "fit for therapy" if no improve functional status -> supportive care
FOLFOX +/- bevacizumab (VEGF) CAPEOX +/- bevacizumab FOLFIRI +/- bevacizumab FOLFOX + (cetuximab/panitumumab)[EGFR] for KRAS WT (Nivolumab [PD1] + ipilimumab [CTLA4]) or pembrolizumab [PD1] for dMMR/MSI-H only
