European Society for Medical Oncology (ESMO)

The European Society for Medical Oncology (ESMO) is the leading professional organisation for medical oncology. With more than 25,000 members representing oncology professionals from over 150 countries worldwide, ESMO was founded in 1975.
Previous studies have reported that an elevated neutrophil-to-lymphocyte ratio is associated with an increased risk of relapse and worse survival in women with breast cancer. Additional data about the prognostic role for this biomarker in patients with early breast cancer are presented here. Read More ›

In this ongoing phase 2 study, postmenopausal women with hormone receptor–positive (HR+)/human epidermal growth factor receptor 2–negative (HER2–) breast cancer are being treated with abemaciclib (a selective inhibitor of cyclin-dependent kinases 4 and 6), anastrozole (an aromatase inhibitor), or both simultaneously.

This study is designed to compare treatment with palbociclib (a cyclin-dependent kinase 4/6 inhibitor) in combination with letrozole (an aromatase inhibitor) versus placebo with letrozole in postmenopausal women with estrogen receptor–positive (ER+)/human epidermal growth factor receptor 2–negative (HER2–) advanced breast cancer. A secondary outcome measure of the study, the analysis of tumor tissue biomarkers, is presented here. Read More ›

PM01183 (lurbinectedin) is an investigational compound that blocks transactivated transcription and induces the formation of double-strand breaks in a range of cancer lines. This study is designed to evaluate whether the presence of BRCA1/2 mutations can act as a prognostic indicator of response to PM01183 in patients with metastatic breast cancer. Read More ›

The objective of this study is to evaluate the efficacy and safety of everolimus (an inhibitor of mammalian target of rapamycin) in combination with letrozole (an aromatase inhibitor) in postmenopausal women with advanced estrogen receptor–positive (ER+)/human epidermal growth factor receptor 2–negative (HER2–) breast cancer.

Using the EQ-5D Health Index during the course of treatment, this study compares patient-reported general health status during treatment with palbociclib (a cyclin-dependent kinase 4/6 inhibitor) plus fulvestrant (a complete estrogen receptor antagonist) compared with during treatment with fulvestrant alone. Read More ›

Fulvestrant (a complete estrogen receptor [ER] antagonist) represents an endocrine therapy for patients with ER-positive metastatic breast cancer who have disease progression after treatment with an antiestrogen. This study evaluates the clinical benefit rate of fulvestrant 500 mg monthly, defined as complete response, partial response, or stable disease lasting >24 weeks, in women with locally advanced breast cancer.

TAK-228 is an investigational, oral, highly selective, ATP-competitive inhibitor of TORC1/2. By mitigating feedback within the PI3K/AKT/mTOR pathway, TAK-228 may restore sensitivity to endocrine therapies in patients who have progressed on such agents in combination with everolimus. This phase 1b/2 study evaluates the safety, pharmacokinetics, and preliminary efficacy of TAK-228 in combination with exemestane or fulvestrant. Read More ›
