Impact of adjuvant endocrine therapy utilization in male patients with early breast cancer: results from a large German real-world claims data analysis

Male breast cancer (BC) is a rare entity and represents a significant clinical challenge due to its late diagnosis and resulting poorer prognosis compared to female BC. As shown by prior studies, approximately 99% of male BC patients are hormone receptor-positive (HR +). This study aimed to evaluate...

Description
Summary:Male breast cancer (BC) is a rare entity and represents a significant clinical challenge due to its late diagnosis and resulting poorer prognosis compared to female BC. As shown by prior studies, approximately 99% of male BC patients are hormone receptor-positive (HR +). This study aimed to evaluate the utilization and impact of adjuvant endocrine therapy (ET) in male early BC patients using a large German real-world claims dataset.
