Impact of Recurrence Score on Treatment Decisions in Breast Cancer

Impact of Recurrence Score on Adjuvant Treatment Decisions and Tumor Cell Dissemination in Estrogen-receptor Positive and HER2 Negative Patients With Early Breast Cancer

Observational University Hospital Tuebingen · NCT03961880

This study looks at how the OncotypeDX Recurrence Score affects treatment choices for women with early-stage breast cancer to see if it helps doctors decide the best care for them.

What this trial studies

This observational registry aims to assess how the OncotypeDX Recurrence Score influences adjuvant therapy recommendations for women with non-metastatic invasive breast cancer. It will categorize patients based on their Recurrence Score into low, intermediate, and high-risk groups, and evaluate the impact of these scores on tumor cell dissemination. The study will focus on patients who are ER-/PR-positive and HER2-negative, with a nodal status of N0-N1. The research is conducted at the University Hospital Tuebingen, where participants will provide informed consent.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older with unilateral primary non-metastatic invasive breast cancer who meet specific hormonal receptor and nodal status criteria.

Not a fit: Patients with ER-negative or HER2-positive breast cancer, or those with advanced disease, will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective treatment plans for breast cancer patients.

How similar studies have performed: Previous studies utilizing the OncotypeDX Recurrence Score have shown promising results in guiding treatment decisions, indicating a potential for success in this approach.
