Save as Favorite Sign in to receive recommendations Learn more The Oncotype DX test is a genomic test that analyzes the activity of a group of genes that can affect how a cancer is likely to behave and respond to treatment.

The Oncotype DX is used in two ways: The results of the Oncotype DX test, combined with other features of the cancer, can help you make a more informed decision about whether or not to have chemotherapy to treat early-stage, hormone-receptor-positive breast cancer or radiation therapy to treat DCIS.

What are genomic tests? Genomic tests analyze a sample of a cancer tumor to see how active certain genes are. The activity level of these genes affects the behavior of the cancer, including how likely it is to grow and spread.

Genomic tests are used to help make decisions about whether more treatments after surgery would be beneficial. While their names sound similar, genomic testing and genetic testing are very different.

Genetic testing is done on a sample of your blood, saliva, or other tissue and can tell if you have an abnormal change also called a mutation in a gene that is linked to a higher risk of breast cancer.

See the Genetic Testing pages for more information.

Who is eligible for the Oncotype DX test? You may be a candidate for the Oncotype DX test if: After surgery, hormonal therapies such as an aromatase inhibitor or tamoxifen are prescribed to reduce the risk that the cancer will come back in the future.

Whether or not chemotherapy is also necessary has been an area of uncertainty for patients and their doctors. Some research also suggests the test may help postmenopausal women with estrogen-receptor-positive breast cancer that has spread to the lymph nodes make chemotherapy decisions.

Talk to your doctor if you are in this group. You also may be a candidate for the Oncotype DX test if: DCIS usually is treated by surgically removing the cancer lumpectomy in most cases.

After surgery, hormonal therapy may be recommended if the DCIS is hormone-receptor-positive.

Radiation therapy may be recommended for some women. How does Oncotype DX work? The Oncotype DX genomic test analyzes the activity of 21 genes that can influence how likely a cancer is to grow and respond to treatment. Looking at these 21 genes can provide specific information on: Studies have shown that Oncotype DX is useful for both purposes.

You and your doctor can use the following ranges to interpret your results for early-stage invasive cancer: Recurrence Score lower than The cancer has a low risk of recurrence. The benefit of chemotherapy is likely to be small and will not outweigh the risks of side effects.

Recurrence Score of 18 up to and including The cancer has an intermediate risk of recurrence.related to ER and PgR testing for patients with breast cancer.

GUIDELINE QUESTIONS The overall purpose of this guideline is to improve the accuracy of hormone receptor testing and the utility of ER.
