Rashmi K. Murthy, MD, on HER2-Positive Metastatic Breast Cancer: HER2CLIMB Trial of Tucatinib, Capecitabine, and Trastuzumab
2019 San Antonio Breast Cancer Symposium
Rashmi K. Murthy, MD, of The University of Texas MD Anderson Cancer Center, discusses data on the efficacy and safety of tucatinib, trastuzumab, and capecitabine, a treatment regimen under investigation for patients with advanced HER2-positive metastatic breast cancer refractory to standard-of-care regimens (Abstract GS1-01).
Joseph Sparano, MD, of the Montefiore Medical Center, discusses three challenges:
- How can gene-expression profiles and other diagnostic tests be used to guide the use of adjuvant systemic therapy?
- Is it time to reappraise active surveillance?
- Are there diagnostic and therapeutic strategies that can identify tumors at highest risk of metastasis, and novel therapies that can block the spread of disease?
Priyanka Sharma, MD, of the University of Kansas Medical Center, reviews new phase III data on adding oral fluoropyrimidine to adjuvant endocrine therapy, the current standard of care, in the setting of hormone receptor–positive, HER2-negative primary breast cancer (Abstract GS1-09).
Nadine M. Tung, MD, of Beth Israel Deaconess Medical Center, discusses cisplatin vs doxorubicin/cyclophosphamide (AC) as neoadjuvant treatment in BRCA-mutation carriers with HER2-negative breast cancer. Although cisplatin as a single agent shows activity in this setting, the pathologic complete response with this agent alone is not higher than that with standard AC chemotherapy (Abstract GS6-03).
Sara M. Tolaney, MD, MPH, of Dana-Farber Cancer Institute, discusses phase II findings on patients receiving T-DM1 monotherapy as adjuvant treatment for stage I HER2-positive breast cancer, a regimen associated with few recurrences in the study population (Abstract GS1-05).
Hope S. Rugo, MD, of the University of California San Francisco Comprehensive Cancer Center, discusses trial data on margetuximab plus chemotherapy, which improved progression-free survival in patients with previously treated HER2-positive metastatic breast cancer when compared with trastuzumab plus chemotherapy. Maturing data comparing overall survival also provides new insights (Abstract GS1-02).
