Description of Medical Service

The RAS mutation test is a combination of genetic tests, conducted on a biopsy sample, to tell whether a tumour carries a RAS mutation(s). KRAS and NRAS are highly related members of the RAS oncogene family which have an important role in the development and continued growth of colorectal cancer. The KRAS gene is found to be mutated, or changed, in about 40% of people with colorectal cancer. The NRAS gene is found to be mutated in an additional 10-15% of patients. The other ~50% of people have a non-mutated (sometimes called “wild type”) RAS genes.

Description of Medical Condition

Widespread colorectal cancer is treated with chemotherapy and patients may receive several sequential courses of different types of chemotherapy as the disease progresses. For patients with widespread disease the prognosis is poor with only 10% of patients still alive 5 years after diagnosis.
