Estrogen

Estrogens are a family of related molecules that stimulate the development and maintenance of female characteristics and sexual reproduction.

What is Estrogen?

Estrogens (also called Oestrogens) are steroid compounds that are important for development and functioning of females of the species. They are named so because they play an important role in the estrous cycle. Their name comes from estrus/oistros (period of fertility for female mammals) + gen/gonos = to generate.

Machine learning model predicts CDK4/6 inhibitor effectiveness in metastatic breast cancer

A machine learning (ML) model incorporating both clinical and genomic factors outperformed models based solely on either clinical or genomic data in predicting which patients with hormone receptor (HR)-positive, HER2-negative metastatic breast cancer would have better outcomes from adding CDK4/6 inhibitors to endocrine therapy as first-line treatment, according to results presented at the San Antonio Breast Cancer Symposium (SABCS), held December 10-13, 2024.

PATINA trial demonstrates benefit of palbociclib in HR+ HER2+ metastatic breast cancer

Alliance Foundation Trials, LLC (AFT) and Pfizer Inc. today announced results from the phase III PATINA trial demonstrating that the addition of palbociclib (IBRANCE) to current standard-of-care first-line maintenance therapy (following induction chemotherapy) resulted in statistically significant and clinically meaningful improvement in progression-free survival (PFS) by investigator assessment in patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-positive (HER2+) metastatic breast cancer (MBC).

Olaparib provides survival benefits for high-risk BRCA-positive breast cancer patients

Patients with high-risk, BRCA-positive breast cancer who received olaparib (Lynparza) after standard treatment continued to have better survival outcomes than those who received placebo after a median follow-up of 6.1 years, according to the latest results from the phase III OlympiA clinical trial presented at the San Antonio Breast Cancer Symposium (SABCS), held December 10-13, 2024.

Early ovarian removal and APOE4 increase Alzheimer's risk in women

New research published by a team of researchers from the University of Toronto in collaboration with colleagues from the University of Alberta has found that women who have had both ovaries surgically removed before the age of 50 and carry a variant of the apolipoprotein gene, the APOE4 allele, are at high risk of late-life Alzheimer disease (AD). Use of hormone therapy mitigates this risk.

Normal breast tissue cells harbor cancer-like genetic abnormalities

A new study from researchers at The University of Texas MD Anderson Cancer Center finds that, in healthy women, some breast cells that otherwise appear normal may contain chromosome abnormalities typically associated with invasive breast cancer. The findings question conventional thinking on the genetic origins of breast cancer, which could influence early cancer detection methods.
