Purpose Of Review: Pre-operative endocrine therapy can be used to down-stage large or locally advanced breast cancers in ER+ disease. In the last four decades, it has evolved from a treatment perceived as an alternative to surgery for those too unfit to undergo surgery or chemotherapy, to the present day where it is a valuable and valid option in the treatment of postmenopausal women with ER-rich (Allred score 7-8, or > 50% staining for ER) breast cancer.
Recent Findings: Emerging data from the metastatic setting is translating into neoadjuvant trials, utilising dual endocrine targeting or combinations of endocrine agents and other targeted drugs, including those acting against components of the PI3K pathway and the cell cycle. The routine use of peri-operative endocrine therapy in all ER+ tumours may help to yield important long-term prognostic information, and guide adjuvant endocrine therapy.
Summary: Pre-operative endocrine therapy is an exciting and evolving area with emerging new approaches. In this review, established evidence and emerging data on its applications are discussed.

PLK1 overexpression suppresses homologous recombination and confers cellular sensitivity to PARP inhibition.
Sci Rep

Department of Frontier Medicine, Institute of Medical Science, Graduate School of Medicine, St. Marianna University, Kawasaki, 2168511, Japan.
The overexpression of Polo-like kinase 1 (PLK1) is associated with poor clinical outcomes in various malignancies, making it an attractive target for anticancer therapies. Although recent studies suggest PLK1's involvement in homologous recombination (HR), the impact of its overexpression on HR remains unclear. In this study, we investigated the effect of PLK1 overexpression on HR using bioinformatics and experimental approaches.

Undescended testis and testicular torsion represent two frequent andrological diseases that affect the pediatric age. Despite these testicular disorders having different causes, they both negatively influence fertility in adulthood mainly due to the accumulation of reactive oxygen species (ROS), which represents the primary molecular damage underlying their long-term effects. The gold standard of treatment for both pathologies is surgery; however, it cannot guarantee an optimal fertility outcome in all clinical cases, underscoring the need to identify effective adjuvant therapies that may target the augmented ROS levels.

Breast cancer is the most prevalent malignant tumour among women. Approximately 70 % of patients are hormone receptor (HR)-positive and undergo endocrine therapy as the main form of treatment; however, the efficacy of this type of therapy is limited by some factors, such as drug resistance and complex tumour microenvironments. Using network pharmacology and molecular docking, this study examined how CDK4/6 inhibitors enhance the effects of immunotherapy for HR-positive breast cancer, focusing on their effects on the tumour microenvironment (TME) and immune cell activity.

FGFR2-RUNX2 activation: An unexplored therapeutic pathway in luminal breast cancer related to tumor progression.

Overcoming luminal breast cancer (BrCa) progression remains a critical challenge for improved overall patient survival. RUNX2 has emerged as a protein related to aggressiveness in triple-negative BrCa, however its role in luminal tumors remains elusive. We have previously shown that active FGFR2 (FGFR2-CA) contributes to increased tumor growth and that RUNX2 expression was high in hormone-independent mouse mammary carcinomas.
