Introduction: T-DM1 has been approved for the treatment of HER2+ breast cancer. Cardiac dysfunction is a side effect of trastuzumab, a component of T-DM1. However, little is known about T-DM1-associated cardiotoxicity. Methods: We have conducted a pooled analysis of T-DM1 trials in advanced HER2+ breast cancer cases to understand the incidence,...

Background Several endocrine therapy (ET)-based treatments are available for patients with advanced breast cancer. We assessed the efficacy of different ET-based treatments in patients with hormone receptor-positive/HER2-negative advanced breast cancer with endocrine-sensitive or endocrine-resistant disease. Methods We searched Medline and...

BACKGROUND: The potential gonadotoxicity of anti-HER2 agents remains largely unknown, and limited, conflicting evidence exists for taxanes. Antimüllerian hormone (AMH) is an established biomarker of ovarian reserve that may aid in quantifying anticancer treatment-induced gonadotoxicity. PATIENTS AND METHODS: The present biomarker analysis of...

Background: Biomarkers for cyclin-dependent kinase 4/6 inhibitors, such as palbociclib, for patients with hormone receptor-positive/HER2-negative metastatic breast cancer are lacking. Thymidine kinase is a proliferation marker downstream of the cyclin-dependent kinase 4/6 pathway. We prospectively investigated the prognostic role of serum...

Background: The MINDACT trial showed excellent 5-year distant metastasis-free survival of 94·7% (95% CI 92·5–96·2) in patients with breast cancer of high clinical and low genomic risk who did not receive chemotherapy. We present long-term follow-up results together with an exploratory analysis by age. Methods: MINDACT was a multicentre,...
