Some women with early-stage breast cancer forego chemotherapy

A research study named the “Trial Assigning Individualized Options for Treatment” (TAILORx) asked whether chemotherapy is beneficial for women who have mid-range Oncotype DX tumor recurrence scores. This trial — the largest breast cancer treatment trial ever conducted— showed that endocrine therapy alone was as effective as endocrine therapy plus chemotherapy in women with certain types of early-stage breast cancer. The results of this trial are expected to be immediately practice changing (7/20/18)
Questions To Ask Your Health Care Provider
- What are the side effects of chemotherapy?
- Will chemotherapy lower my risk for a recurrence?
- Is it possible that I can be treated with endocrine therapy alone and forego chemotherapy?
- Are there any other tests that may help determine the best treatment for me?
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.
