Summary
This study looks at whether a specific gene change (HSD3B1) affects how well the drug letrozole works in postmenopausal women with early-stage, hormone-sensitive breast cancer. Researchers will measure changes in tumor markers before and after treatment. The goal is to understand why some patients respond better than others, not to provide a new treatment.
