Neoadjuvant Letrozole in Postmenopausal Women With Hormone Receptor-Positive, HER2-Negative, Node Positive, Early-Stage Breast Cancer.
NCT07394946 · Status: NOT_YET_RECRUITING · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 126
Last updated 2026-02-20
Summary
The goal of this clinical trial is to learn whether letrozole, a hormone therapy drug, is effective in treating early-stage, hormone receptor-positive, HER2-negative breast cancer that has spread to nearby lymph nodes in postmenopausal women. The study will also evaluate the safety of taking letrozole for one year before surgery.
The main questions this study aims to answer are:
Can one year of letrozole eliminate cancer from the underarm (axillary) lymph nodes?
Can treatment with letrozole reduce the need for extensive lymph node surgery?
How safe and tolerable is long-term letrozole treatment?
This is a single-arm study, meaning all participants will receive letrozole. There is no placebo or comparison group.
Participants will:
Take letrozole 2.5 mg by mouth once daily for one year
Attend regular clinic visits for physical exams, blood tests, and imaging studies
Undergo surgery after completing treatment
Be followed for up to two years to monitor cancer recurrence and survival
Conditions
- Hormone Receptor-Positive, HER2-Negative, Node Positive Breast Cancer
Interventions
- DRUG
-
Letrozole is an oral aromatase inhibitor administered at a dose of 2.5 mg once daily for one year. It is used as neoadjuvant therapy in postmenopausal women with early-stage, hormone receptor-positive (ER+/PR+), HER2-negative, node-positive breast cancer to reduce tumor size and axillary lymph node involvement before surgery.
