KRAS mutation is a re-occuring theme in molecular pathology. KRAS is an oncogene.[1]
General
Seen in:
Implication
In the context of colorectal carcinoma:[3][4]
- Patient must have wild type KRAS to get drugs; KRAS mutation predicts resistance to cetuximab (Erbitux) and panitumumab (Vectibix).
Microscopic
Features:
- Typically mucinous carcinoma.
