Breast cancer is a major health problem in developed countries. Endocrine therapy is a key component in the management of hormone receptor-positive disease. Although tamoxifen has historically been the gold standard in the first-line management of early and advanced breast

Multiple studies suggest better efficacy of chemotherapy in invasive ductal breast carcinomas (IDC) than invasive lobular breast carcinomas (ILC). However, data on efficacy of adjuvant endocrine therapy regimens and histological subtypes are sparse. This study assessed endocrine therapy efficacy in

For postmenopausal patients with hormone-sensitive breast cancer, outcome is worse with increasing age at diagnosis. The aim of this study was to assess the incidence of breast cancer recurrence (locoregional and distant), and contralateral breast cancer by age at diagnosis.

Insulin-like growth factors (IGF-1 and IGF-2) bind to the IGF-1 receptor (IGF-1R), increasing cell proliferation and survival. Ganitumab is a monoclonal IgG1 antibody that blocks IGF-1R. We tested the efficacy and safety of adding ganitumab to endocrine treatment for patients
Anneleen Lintermans et al.
Expert opinion on drug safety, 10(3), 473-487 (2011-03-25)
Hormone-dependent breast cancer can be successfully treated by either blocking the estrogen receptor, as with tamoxifen, or reducing the production of estrogens, as with aromatase inhibitors. Exemestane is a third-generation aromatase inhibitor used in the treatment of estrogen-receptor-positive breast cancer
