Evaluating a test to predict benefits of extended hormone therapy for breast cancer

Evaluation of the Sensitivity to Endocrine Therapy (SET ER/PR) Assay to predict benefit from extended duration of adjuvant endocrine therapy in the NSABP B-42 trial

NIH-funded research University of Tx Md Anderson Can Ctr · NIH-10932233

This study is looking at a special test that checks how well breast cancer tumors respond to hormone therapy, so doctors can better recommend treatment for patients who have finished five years of initial therapy and may benefit from continuing it to improve their chances of staying cancer-free.

What this research studies

This research investigates the SET ER/PR assay, which measures how sensitive breast cancer tumors are to endocrine therapy by analyzing tumor samples. The assay aims to predict which patients will benefit from an extended duration of hormone therapy after initial treatment. By correlating receptor activity with treatment response, the study seeks to provide personalized treatment recommendations for patients who have completed five years of adjuvant endocrine therapy. The findings could help improve disease-free survival rates for breast cancer patients.

Who could benefit from this research

Good fit: Ideal candidates for this research are breast cancer patients who have completed five years of adjuvant endocrine therapy and are considering extended treatment.

Not a fit: Patients who have not undergone endocrine therapy or those with non-hormone receptor-positive breast cancer may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to more personalized and effective treatment plans for breast cancer patients, potentially improving their long-term outcomes.

How similar studies have performed: Previous research has shown promising results with similar assays in predicting treatment responses, indicating a potential for success in this approach.
