Special Issue Information

Dear Colleagues,

Hormone-receptor-positive and HER2-negative breast cancer is the most common type of breast cancer. Endocrine therapy is the mainstay of treatment, and many patients do not need any other treatment. In both advanced and early cancer, additional therapies aiming at overcoming resistance have been developed. The emergence of novel targeted therapy in combination with endocrine therapy has shown improvement in outcomes, and may even make cytotoxic chemotherapy unnecessary in more patients in the future. In particular, CDK4/6 inhibitors and novel SERDs are promising options for the future. In this Special Issue of Cancers, we welcome original research and comprehensive review articles focusing on recent developments in the treatment of hormone-receptor-positive breast cancer, including special topics such as premenopausal patients and neoadjuvant treatment approaches.

Seventy percent of all breast cancer subtypes are hormone receptor-positive. Adjuvant endocrine therapy in these patients plays a key role. Despite the traditional duration of a 5-year intake, the risk of relapse remains elevated in a substantial proportion of patients. Several trials report that the risk of late recurrence is reduced by the extension of adjuvant endocrine therapy beyond 5 years. However, the optimal duration of endocrine therapy is still a matter of debate. The newer data only show a marginal benefit resulting from extension beyond 7 to 10 years. Furthermore, extension may be associated with more side effects. Thus, the adequate selection of patients qualifying for an extended adjuvant therapy is of importance. Tools/genomic tests, which include the characteristics of the patient and the tumor, may help to better identify patients with a risk of a late relapse. Taken together, the magnitude of benefit for extended adjuvant endocrine therapy is based on the precise estimation of the risk of relapse after 5 years. This must be balanced against the long-term side effects of endocrine treatment and the competing risks. For patients with an intermediate risk, 7 years appears to be the optimal duration, and in those with high-risk features, endocrine therapy up to 10 years may be considered. Full article
