Micrograph showing mucinous carcinoma, a histology associated with KRAS mutations.
KRAS mutation is a re-occuring theme in molecular pathology. KRAS is an oncogene.[1]
General
Seen in:
Not seen in the context of:
- ALK rearrangements in non-small cell lung cancer.[3]
Implication
In the context of colorectal carcinoma:[4][5]
- Patient must have wild type KRAS to get drugs; KRAS mutation predicts resistance to cetuximab (Erbitux) and panitumumab (Vectibix).
Microscopic
Features:
- Typically mucinous carcinoma in lung.[6]
- No correlation in colorectal carcinoma.[7]
