DESCRIPTION
Laboratory tests have been developed to detect the expression of 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 individuals with early-stage breast cancer. Test results may help determine whether to include adjuvant chemotherapy in post-surgical management of breast cancer. In addition to guiding treatment decisions related to chemotherapy, Breast Cancer index™ has been validated to predict late distant recurrence risk and endocrine responsiveness when considering extension of endocrine therapy.
Most individuals with newly diagnosed, early-stage or nonmetastatic breast cancer are disease-free after initial local and regional treatment; however, almost a third of women develop metastasis by the 5 – 10-year follow-up.
Examples of Gene Expression Assays for Breast Cancer:
Test |
Description |
Breast Cancer Index™ |
6-11 gene predictor for risk of late recurrence at 5 to 10 years; Predictive of benefit of extended adjuvant endocrine therapy |
EndoPredict® |
12-gene molecular score for early and late recurrence |
MammaPrint® |
70 gene analysis; provides low – high risk classification for 10 year prognosis |
Oncotype DX® for Breast Cancer |
21-gene assay; Recurrence Score® of 0 – 100 provides 10 year prognosis information |
Prosigna® (PAM 50) |
Digital analysis system based on prediction of 50 gene microarray; giving a numerical value of 0-100 that correlates with the probability of recurrence within 10 years. |
