The recurrence score derived from a 21-gene expression assay may indicate which patients with early-stage HR+ breast cancer can maintain freedom from distant recurrence for longer with the inclusion of an anthracycline in adjuvant chemotherapy, suggests a post hoc analysis of the TAILORx trial presented at SABCS 2024

A large global study provides evidence that risk-reducing mastectomy (RRM) and/or risk-reducing salpingo-oophorectomy (RRSO) is associated with improved survival outcomes in young women diagnosed with breast cancer (BC) at or before 40 years of age who were harbouring germline BRCA1 and/or BRCA2 pathogenic variants (PVs).

The addition of the CDK4/6 inhibitor palbociclib to anti-HER2 and endocrine therapy (ET) significantly improves progression-free survival (PFS) in patients with hormone receptor-positive, HER-positive (HR+, HER+) metastatic breast cancer (mBC) in the first-line setting, according to the results of the phase III AFT-38 PATINA trial.

First-line endocrine therapy (ET) plus palbociclib (palb/ET) performs better than mono-chemotherapy in improving time to treatment failure (TTF) and progression-free survival (PFS) in women with hormone receptor-positive (HR+), HER2-negative metastatic breast cancer (mBC), as shown by the results of the phase III PADMA trial.

Treatment with trastuzumab deruxtecan (T-DXd) results in longer progression-free survival (PFS) in patients with hormone receptor–positive, HER2-low or HER2-ultralow metastatic breast cancer (mBC) compared with physician’s choice of chemotherapy, according to the results of the phase III DESTINY-Breast06 study presented at SABCS 2024. In addition, no new safety signals have been identified.
