Two studies presented at the December 2020 San Antonio Breast Cancer Symposium looked at how tumor testing can identify patients who may benefit the most and the least from chemotherapy. (3/4/21)

Questions To Ask Your Health Care Provider
- What tumor tests have I had?
- How are my tumor test results being used to guide my treatment?
- Can I safely skip chemotherapy?
- With my tumor test results, what are the chances that my cancer will come back?
Open Clinical Trials
The following are studies enrolling people with early stage ER-positive, HER2-negative breast cancer.
- NCT04016935: EndoPredict® Extended Endocrine Trial (EXET). This study is looking at the 5 to 10-year outcomes of patients with hormone receptor-positive, HER2-negative early-stage breast cancer tumors with low EndoPredict® (a tumor test used to predict whether cancer will come back after 10 years) scores who did not continue hormone therapy after 5 years.
- NCT03053193: MammaPrint, BluePrint, and Full-genome Data Linked With Clinical Data to Evaluate New Gene EXpression Profiles (FLEX). The FLEX Registry is a large-scale, population based, prospective registry. All patients with stage I to III breast cancer who receive MammaPrint® and BluePrint testing on a primary breast tumor are eligible for entry into the FLEX Registry.
- NCT04129216: The Effects of Short-term Preoperative Treatment with Hormonal Therapy on Gene Profiles in Breast Cancer. This study is studying how the expression of the Ki-67, estrogen and progesterone receptor genes change after a short course of hormonal therapy before surgery in patients with breast cancer. The goal of this study is to advance personalized treatment for women with breast cancer.
- NCT03749421: Prosigna Assay on Neoadjuvant Clinical Decision-making in Women With HR+/Her2- Breast Cancer. This research study is evaluating a genomic analysis called Predictor Analysis of Microarray 50 (PAM50, by Prosigna®) as a tool to possibly guide the participant and the treating physician to choose the most personalized pre-operative treatment for breast cancer.
- NCT04875351: Breast Cancer Index (BCI) Registry. The purpose of the study is to evaluate long-term clinical outcome, clinical impact, medication adherence and quality of life in hormone receptor positive (HR+) early-stage breast cancer patients receiving BCI testing as part of routine clinical care to inform extended endocrine therapy.
- NCT03725059: Pembrolizumab Versus Placebo With Neoadjuvant Chemotherapy & Adjuvant Endocrine Therapy for Early-Stage Estrogen Receptor-Positive, HER2-Negative Breast Cancer (KEYNOTE-756). This study will assess how well pembrolizumab works compared to placebo in combination with neoadjuvant (pre-surgery) chemotherapy and adjuvant (post-surgery) hormonal therapy in the treatment of high-risk early-stage estrogen receptor-positive, HER2-negative breast cancer.
NCT04852887: De-Escalation of Breast Radiation Trial for Hormone Sensitive, HER-2 Negative, Oncotype Recurrence Score Less Than or Equal to 18 Breast Cancer (DEBRA). This study evaluates whether breast conservation surgery and endocrine therapy results in a non-inferior rate of invasive or non-invasive ipsilateral breast tumor recurrence (IBTR) compared to breast conservation with breast radiation and endocrine therapy.
