In patients with HER2+ breast cancer, those who achieved a pathologic complete response following HER2-directed (trastuzumab and/or pertuzumab) neoadjuvant therapy had an increased event-free survival probability compared with patients with residual disease. Read Article ›

In the largest retrospective analysis of US patients with ER+/HER2+ nonmetastatic breast cancer, there was no overall survival benefit of treating patients with hormone therapy + trastuzumab compared with hormone therapy alone, and patients treated without chemotherapy had a significantly worse overall survival.

IL6ST levels can differentiate ER+/HER2+ patients with breast cancer who respond well to endocrine therapy alone versus those with a poor clinical response who have a higher risk of recurrence, suggesting that there is a potential role for IL6ST in selecting ER+/HER2+ patients who require and benefit from HER2-targeted therapies.
