Breast Cancer Gene Expression Assays

DESCRIPTION

Laboratory tests have been developed that detect the expression of many different genes in breast tumor tissue and combine the results into a prediction of distant recurrence risk (return of detectable cancer in another part of the body) for women with early-stage breast cancer.  Test results may help determine whether to include adjuvant chemotherapy in post-surgical management of breast cancer.

For women with early-stage invasive breast cancer considering adjuvant chemotherapy who receive gene expression profiling using one of the assays listed below, a low score is associated with a low risk of recurrence.

Tests intended to assess estrogen receptor, progesterone receptor and HER2 status, such as TargetPrint®, and tests that do not provide a specific recurrence risk are outside the scope of this policy.
