The tumour microenvironment influences long-term tamoxifen benefit in postmenopausal ER+/HER2- breast cancer patients

2026-03-26

Abstract excerpt

<h4>ABSTRACT</h4> <h4>Background</h4> The tumour microenvironment (TME) influences breast cancer progression and treatment response. We investigated whether TME composition predicts tamoxifen benefit in postmenopausal women with oestrogen receptor-positive, HER2-negative (ER+HER2-) breast cancer. <h4>Methods</h4> This study included 513 patients from the Stockholm Tamoxifen (STO-3) trial, which randomised postm...
