"Breast Cancer Index, a second generation tool designed to answer questions about recurrence and inform treatment decisions, now has demonstrated meaningful and significant prognostic accuracy vs Oncotype RS for early-stage, ER+, lymph node-negative patients," said Nicolas Barthelemy, president and CEO of Biotheranostics. "Our test will help enhance personalized breast cancer treatment, by identifying accurate risk of recurrence throughout the patient journey."
In the independent TransATAC study, existing tumor samples of 665 postmenopausal women with lymph node-negative, hormone receptor-positive breast cancer treated with either tamoxifen or anastrozole alone were evaluated. Analysis began at diagnosis through year 10. BCI Risk Score and Oncotype DX RS were compared to determine prognostic strength.
About Breast Cancer IndexSM
BCI is a molecular, gene expression-based test uniquely positioned to help identify patients best suited for extended endocrine treatment. It is the only validated, commercially available test with data demonstrating prognostic risk of recurrence out to 15 years, as well as prediction of likelihood of benefit from extended endocrine therapy (treatment in years 5-10). The breakthrough test helps oncologists and patients navigate the difficult trade-off between wanting to take steps to prevent recurrence of their disease and facing significant side effects and safety challenges related to extended endocrine therapy.

Biotheranostics, Inc., is a leader in helping physicians improve the care of cancer patients, offering a suite of proprietary molecular diagnostic tests that allow treatment to be tailored to individual patients. The company's CancerTYPE ID® is the most rigorously validated gene expression test for metastatic patients with diagnostic ambiguity, helping physicians determine optimal site-directed treatment regimens with the goal of improving patient outcomes. Its Breast Cancer IndexSM helps oncologists make difficult decisions about extended endocrine therapy for ER+ breast cancer patients based on its unique ability to predict risk of late disease recurrence and identify which patients are likely to benefit from continuing therapy beyond five years. Biotheranostics is based in San Diego. For more information, visit www.biotheranostics.com
