Special Issue Information

Dear Colleagues,

Endocrine therapy is the standard of care in hormone-receptor-positive breast cancer (HR+ BC).

Understanding the mechanisms of intrinsic resistance in addition to the molecular pathways activated by cancer cells after exposure to endocrine therapy has led to the development of highly active treatments, some of which have resulted in significantly improved survival.

CDK4/6 inhibitors are now part of clinical practice in adjuvant and metastatic settings; many clinical trials are exploring the role of new targeted agents in adjuvant and neoadjuvant settings of the disease. 

Other new drugs (SERDs, CDK7 inhibitors, and PI3K/akt/mTor inhibitors) are increasingly appearing in metastatic settings. Moreover, antibody-drug conjugates (ADCs) have recently demonstrated their clinical efficacy regardless of the expression of hormone receptors, as have PROTACTs (PROteolysis Targeting Chimeras), new small molecules designed to escape endocrine resistance mechanisms.

The aim of this Special Issue is to report the state of the art in the treatment of HR+ BC and analyze the new challenges to be addressed: redefining escalation and de-escalation strategies based on the risk of disease recurrence in an adjuvant setting and on the disease burden in a metastatic setting; identifying the optimal treatment sequence; understanding the role of ADCs in HR+ BC and the role of predictive biomarkers of responses that have been identified so far (PI3K, BRCA, and ESR1 mutations, as well as, more recently, the low expression of HER2).

Breast cancer (BC) in elderly women is an increasing health issue due to demographic changes. BC tends to present later and may receive less than standard treatment options. More often, BC in elderly patients is endocrine-positive (HR+). The treatment of elderly patients with metastatic BC (mBC) represents a therapeutic challenge. In recent years, the treatment landscape of patients that are HR+/Her2-negative has changed due to the introduction in clinical practice of new targeted drugs, which have improved patient outcomes. Elderly patients are a small percentage of all patients enrolled in clinical trials and, to date, there are no standardized guidelines that define the best treatment option for this patient population. This can lead to undertreatment or overtreatment, impacting patient morbidity and mortality. Geriatric Assessment tools to tailor the treatment in elderly patients are underused because they are long and difficult to apply in a busy routine clinical practice. For all these reasons, there is an urgent need to produce data about the best treatment for elderly patients with HR+ mBC. Herein, we report data from randomized clinical trials and real-world evidence on the therapeutic options for HR+ Her2-negative mBC elderly patients and explore future treatment directions.
