HER2-positive breast cancer accounts for 20–30% of all breast cancers and has the second-poorest prognosis among breast cancer subtypes. The approval of trastuzumab in 1998 has significantly improved ...

Trastuzumab deruxtecan is approved for HR-positive, HER2-low/ultralow metastatic breast cancer post-endocrine therapy, based on DESTINY-Breast06 trial results. The trial showed a 36% reduction in ...

At seven-years follow up, invasive disease-free survival was 80.8% with adjuvant T-DM1 and 67.1% with adjuvant trastuzumab alone. Overall survival was 89.1% with T-DM1 and 84.4% with trastuzumab ...

The primary analysis of KATHERINE, a phase 3, open-label trial, showed that the risk of invasive breast cancer or death was 50% lower with adjuvant trastuzumab emtansine (T-DM1) than with ...

In patients with high-risk HER2-positive breast cancer, post-surgery, or adjuvant, treatment with trastuzumab emtansine (T-DM1) reduced the long-term risk of death or invasive disease by 46% and ...

Trastuzumab emtansine (T-DM1) demonstrates sustained improvement in invasive disease-free survival and reduced the risk for death in human epidermal growth factor receptor 2 (HER2)-positive breast ...

Adjuvant therapy with trastuzumab emtansine has shown improved outcomes. New research findings are summarized in a short video.

Trastuzumab, tested only as a single agent, has been shown to achieve 7% response in heavily pretreated patients with AOC with 3+ and 2+ HER2 immunostaining by immunohistochemistry (IHC).
