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]

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).

Gross

In colorectal cancer:

  • Typically right sided lesions.[6]
