Researchers at Penn State have successfully 3D bioprinted breast cancer tumors and treated them in a breakthrough study to better understand the disease that is one of the leading causes of mortality worldwide. Read More ›

Young women with early-stage, hormone receptor (HR)-positive breast cancer attempting to become pregnant can safely pause endocrine therapy and resume it later, according to initial results from the international POSITIVE trial. Read More ›

On January 27, 2023, the FDA approved elacestrant (Orserdu; Stemline Therapeutics), an estrogen receptor (ER) antagonist, for the treatment of postmenopausal women or adult men with ER-positive, HER2-negative advanced or metastatic breast cancer and an ESR1 mutation whose disease progressed after ≥1 line of endocrine therapy.

On February 3, 2023, the FDA approved sacituzumab govitecan-hziy (Trodelvy; Gilead Sciences/Immunomedics) for the treatment of patients with unresectable, locally advanced or metastatic hormone receptor (HR)-positive, HER2-negative (immunohistochemistry [IHC] 0, IHC 1+, or IHC 2+ with a negative in situ hybridization test) breast cancer who have received endocrine-based therapy and at least 2 additional systemic therapies in the metastatic setting.

Using circulating tumor cell (CTC) count to guide the choice of first-line treatment—chemotherapy or endocrine therapy—improved overall survival (OS) compared with investigator’s choice of treatment for patients with metastatic, estrogen receptor (ER)-positive, HER2-negative breast cancer, according to results from the STIC CTC trial.

In patients with hormone receptor (HR)-positive, HER2-low or -negative, locally advanced or metastatic breast cancer resistant to aromatase inhibitors, the addition of the investigational first-in-class AKT inhibitor capivasertib (AZD5363) to fulvestrant (Faslodex) led to a statistically significant and clinically meaningful improvement in progression-free survival (PFS) compared with placebo plus fulvestrant.

Patients with hormone receptor (HR)-positive, HER2-negative advanced breast cancer, including those with visceral crises, treated with the CDK4/6 inhibitor ribociclib (Kisqali) plus endocrine therapy had a significantly longer progression-free survival (PFS) and fewer adverse events (AEs) compared with those treated with combination chemotherapy, according to results from the phase 2 RIGHT Choice trial.

Several baseline factors were associated with an increased risk for treatment discontinuation in the phase 3 monarchE clinical trial, which assessed adjuvant abemaciclib (Verzenio) in patients with hormone receptor–positive, HER2-negative early breast cancer, according to findings from a multivariate analysis presented during the American Society of Clinical Oncology Annual Meeting.

Endocrine therapy after breast-­conserving surgery may be the only treatment needed in patients aged ≥55 years with low-grade luminal type A breast cancer, sparing them radiation therapy, including its side effects, financial burden, and inconvenience, according to findings from the single-arm LUMINA clinical trial reported at the 2022 American Society of Clinical Oncology Annual Meeting.

The investigational oral selective estrogen receptor degrader (SERD) elacestrant (RAD1901) significantly reduced the risk for death or disease progression and improved progression-free survival (PFS) compared with standard of care (SOC) endocrine therapy in patients with estrogen receptor (ER)-­positive, HER2-negative metastatic breast cancer who had progressed on previous endocrine and targeted therapies, according to results of the phase 3 EMERALD clinical trial.
