Circulating tumor DNA in early breast cancer: Evidence, challenges, next steps

Circulating tumor DNA (ctDNA) is a tumor-derived, circulating bioanalyte that can be detected in blood using minimally invasive, blood-based biomarker procedures and has prognostic value in early breast cancer. Quantitative features of ctDNA, including baseline detectability and levels, have shown prognostic potential in early breast cancer by reflecting tumor burden and biologic aggressiveness, thereby supporting risk stratification … Continua a leggere

Interplay between HER2-Low status, hormone receptor expression, and therapeutic response to cyclin-dependent kinase 4/6 inhibitors as first-line treatment in luminal-like metastatic breast cancer: The CYCLHER study

Background: In hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) metastatic breast cancer (mBC), the prognostic significance of estrogen receptor (ER), progesterone receptor (PgR), and HER2 immunohistochemical expression levels in patients treated with cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) remains unclear. The CYCLHER study was designed to evaluate treatment outcomes and identify biologically driven prognostic factors … Continua a leggere

Background: Tumour-infiltrating lymphocytes (TILs) are a robust prognostic marker in patients with triple-negative breast cancer. Artificial intelligence (AI)-derived computational tools assessing TILs could improve efficiency, but require independent validation against clinical outcomes. We aimed to compare the prognostic performance of AI-derived TIL scores with pathologist-scored TILs in a large, prospectively collected dataset pooled from randomised controlled trials … Continua a leggere

Elacestrant in Combination with Everolimus for Estrogen Receptor-Positive, HER2-Negative Previously Treated Advanced Breast Cancer: Results from ELEVATE

Purpose: Treatment options for progression on first-line endocrine therapy (ET)+CDK4/6i for ER-positive/HER2-negative (ER+/HER2-) advanced breast cancer (ABC) include ET plus targeted agents (CDK4/6i or PI3K/AKT/mTOR-pathway inhibitors). Elacestrant is the first single-agent oral SERD that significantly improved progression-free survival (PFS) versus standard-of-care ET in ESR1-mutated and overall ER+/HER2- ABC populations … Continua a leggere
