Task: Answer Verification
Input (English): Question: Does eSR1 promoter hypermethylation predict atypia in RPFNA nor persistent atypia after 12 months tamoxifen chemoprevention?
Answer: Results from this single institution pilot study provide evidence that, unlike for invasive breast cancer, ESR1 promoter hypermethylation and/or low ER expression is not a reliable marker of tamoxifen-resistant atypia.
Output (English): no
