Endocrine Therapy in Treating Patients With HER2 Negative, Low Risk Breast Cancer

December 26, 2018 updated by: Fred Hutchinson Cancer Center

An Investigator Initiated Registry of Simple Oral Therapy for Low Risk Breast Cancer (SOLR)

This pilot clinical trial studies how well endocrine therapy works in treating patients with HER2 negative, low risk breast cancer. Estrogen can cause the growth of breast cancer cells. Endocrine therapies such as aromatase inhibitors and selective estrogen receptor modulators may lessen the amount of estrogen made by the body.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

PRIMARY OBJECTIVES:

I. To estimate the conversion rate from a standard low-toxicity approach to guideline-directed therapy which includes surgery +/- radiation therapy as a result of progression of disease or patient/provider choice.

II. To examine factors that might differ between those who convert from the low-toxicity approach to the guideline-directed therapy and those do not convert.

SECONDARY OBJECTIVES:

I. To measure the safety and clinical effectiveness of systemic endocrine therapy used in a prolonged neoadjuvant fashion.

II. To evaluate the impact of risk-stratified care in Quality-Adjusted Life Years (QALY) and QALY gains.

III. To estimate the cost savings of indefinitely delaying surgery and radiation in favor of systemic endocrine therapy alone.

OUTLINE:

Patients receive exemestane orally (PO) once daily (QD), anastrozole PO QD, letrozole PO QD, tamoxifen citrate PO QD, or toremifene citrate PO QD at the discretion of the treating physician. Treatment continues in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.
