Study Summary

This trial will test whether giving hormone therapy to early-stage breast cancer patients before surgery results in higher rates of margin-negative lumpectomies.

Who is the study for?
This trial is for postmenopausal women with early stage I-II, estrogen-rich breast cancer that's not spread to lymph nodes. They must be able to take anti-endocrine therapy and sign a consent form. Women with progesterone-negative tumors, high-grade tumors, other cancers, or allergies to the study drugs can't join.Check my eligibility
What is being tested?
The study tests if using neoadjuvant endocrine therapy (Anastrozole, Letrozole, Exemestane or Tamoxifen) before surgery improves outcomes in breast cancer by increasing the chances of completely removing the tumor without leaving any cancerous tissue at the edges.See study design
What are the potential side effects?
Possible side effects include hot flashes, joint pain, muscle aches, fatigue, increased sweating and mood swings. Rarely there might be bone thinning or changes in cholesterol levels.
