NCT03238703

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Conversion from oral endocrine therapy for any reason to guideline-directed therapy

    Includes clinical or radiographic progression, patient preference, endocrine therapy intolerance or toxicity, or death from any cause. Descriptive statistics will be summarized among all patients and patients within each of the two groups (stay with oral therapy vs conversion due to any causes).

    Up to 5 years

Secondary Outcomes (7)

  • Advanced imaging (if performed on any subset of patients)

    Up to 5 years

  • Cost-effectiveness and patient-centeredness outcomes defined as financial toxicity and solubility, quality of life (physical, mental, emotional changes) on endocrine therapy, and, access to support services

    Up to 5 years

  • Effect of age

    Up to 5 years

  • Effect of comorbidity severity interaction

    Up to 5 years

  • Effect of type of endocrine therapy type (selective estrogen receptor modifier versus aromatase inhibitor)

    Up to 5 years

  • +2 more secondary outcomes

Study Arms (1)

Treatment (AI, SERM)

EXPERIMENTAL

Patients receive exemestane PO 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.

  • Originally identified by screening mammography
  • Characterized by standard diagnostic mammography +/- breast ultrasound
  • Clinically node negative
  • Confirmed by breast magnetic resonance imaging (MRI) in a facility that maintains active American College of Radiology (ACR) accreditation to be of low clinical stage (=\< 2 cm, node negative, unifocal invasive)
  • Estrogen receptor (ER) and progesterone receptor (PR) Allred scored, each \> 5/8
  • Her2 negative using American Society of Clinical Oncology (ASCO)-College of American Pathologists (CAP) guidelines
