testing for treatment selection
tests look at samples of blood, tumor or other tissue for changes or abnormalities caused by cancer. These tests can give doctors clues about the cancer, including:
- how fast the cancer is growing
- which treatments are most likely to work
- whether or not the cancer is responding to treatment or growing
- whether or not the cancer has come back after remission
tests may be used to select treatments, and help patients avoid side effects from treatments that will not work for them. tests used to select a specific treatment are sometimes called companion diagnostic tests. These tests may be done on tumor tissue or on blood. See our Testing section for more information.
Experts recommend that patients with advanced or recurrent melanoma be tested for the following biomarkers:
- Tumor testing can find a specific mutation in a gene known as BRAF. In melanoma, the most common BRAF mutation is called V600E (may also be V600K/R/M/D/G). Patients with a BRAF V600 mutation may benefit from the addition of targeted therapies known as BRAF inhibitors.
Additional tests that may be used for melanoma:
- Tumor testing can find mutations in genes known as KIT and NRAS.
- testing may help identify people who are eligible for certain clinical trials.
Genetic testing for inherited mutations
About 10 percent of melanomas are caused by an . Genetic testing can help people with endometrial cancer and their relatives learn more about their cancer risks and medical options.
Genetic testing for hereditary melanoma is recommended in the following situations:
- personal history of 3 or more melanomas
- melanoma before age 45
- personal history of other cancers or close family members that have had other cancers that might be related to an , including breast, endometrial, pancreatic and brain tumors
See our section on genetic testing for a more complete list of who should consider genetic testing.
