KRAS Mutation (Codons 12 & 13)

TEST NAME

– KRAS Mutation (Codons 12 & 13)
ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ
ABOUT TEST

– K-ras is an oncogene which plays a crucial role in the development of tumours. Mutations in the K-ras gene are
present in approximately 35-45% of colorectal cancers, in 15-50% of lung cancers and in 72-90% of pancreatic
cancers. The mutations have been localized in various DNA sections, including codon 12 and 13. Several
recently published studies have shown that the mutation status can be a prognostic marker for treatment with
EGFR antibodies such as cetuximab (Erbitux, Merck), or panitumumab (Vectibix, Amgen). By knowing a
patient’s K-ras mutation status, oncologists will be able to identify whether a patient can benefit from treatment
with these antibodies, and can individualize cancer therapy for these patients.
