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]
- Nearly mutually exclusive to BRAF (V600E).[4]
Implication
In the context of colorectal carcinoma:[5][6]
- Patient must have wild type KRAS to get drugs; KRAS mutation predicts resistance to cetuximab (Erbitux) and panitumumab (Vectibix).
Gross
In colorectal carcinoma:
- Typically right sided lesions.[4]
Microscopic
Features:
- Typically mucinous carcinoma in lung.[7]
- In colorectal carcinoma:
