What is TAILORx?
TAILORx is one of the first trials to examine a methodology for personalizing cancer treatment. The study has randomized more than 10,200 women with this type of breast cancer at 1,182 sites in the United States, Australia, Canada, Ireland, New Zealand, and Peru.
Does age affect Oncotype score?
Conclusion. The Oncotype DX 21-gene Recurrence Score algorithm is critically affected by patient age. These findings emphasise the need for the consideration of patient age, particularly for women younger than 50, in the development and application of genomic-based algorithms for breast cancer care.
What is the 21-gene recurrence score?
The 21-gene recurrence score (RS) predicts the prognosis of patients with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative early-stage breast cancer and the effectiveness of adding adjuvant chemotherapy on the basis of endocrine therapy to avoid excessive chemotherapy.
When is Oncotype DX indicated?
You may be a candidate for the Oncotype DX Breast DCIS Score Test if: you’ve recently been diagnosed with DCIS. you’re having lumpectomy to remove the DCIS or have had a core biopsy.
What is Nsabp B20?
NSABP Protocol B20, “A Clinical Trial to Determine the Worth of Chemotherapy and Tamoxifen Over Tamoxifen Alone in the Management of Patients with Primary Invasive Breast Cancer, Negative Axillary Nodes and Estrogen-Receptor-Positive Tumors,” enrolled 2,363 patients between October 17,1988, and March 5, 1993, who were …
What is the 21 gene recurrence score?
What is a good Oncotype score?
A score between 21 and 25 means you have a medium risk of the cancer returning if you get hormone treatment. The benefits of chemotherapy may outweigh the risk of side effects. A score between 26 and 100 means you have a higher risk that the disease might come back.
What does an Oncotype score of 20 mean?
Recurrence Score of 16-20: The cancer has a low to medium risk of recurrence. The benefits of chemotherapy likely will not outweigh the risks of side effects. Recurrence Score of 21-25: The cancer has a medium risk of recurrence.
Which is better oncotype or MammaPrint?
Oncotype gives a graded scale of risk broken up into low, intermediate, and high risk categories, whereas MammaPrint is either low or high risk. Oncotype is applicable only to estrogen receptor (ER)–positive tumors; MammaPrint can be used for both ER-positive and ER-negative tumors.
What is a low MammaPrint score?
MammaPrint test results are reported as either a low-risk or a high-risk RS: A low-risk score means that the cancer has a 10% risk of coming back within 10 years without any additional treatments after surgery.
