NCT ID NCT05183828
First seen Jan 26, 2026 · Last updated May 23, 2026 · Updated 18 times
Summary
This study looks at how a specific gene change (HSD3B1) affects the way postmenopausal women with early-stage, hormone-sensitive breast cancer respond to the drug letrozole before surgery. Researchers will measure changes in tumor markers to see if the gene variant makes the drug less effective. The goal is to better understand who benefits most from this treatment, not to provide a new therapy.
