Dual HER2 blockade with trastuzumab and lapatinib was no better than trastuzumab alone in producing pathologic complete responses in metastatic HER2-positive breast cancer patients in the neoadjuvant setting, according to a new study.
Identifying breast cancer patients who are at low risk for chemotherapy-induced nausea and vomiting before the start of treatment may help avoid unnecessary use of antiemetic medications without compromising quality of care.
We acknowledge that the “more is better” approach may not always hold true. For example, preclinical data provided a rationale for combining pertuzumab with T-DM1, but recent reports suggest that this strategy may not prove more effective than single-agent T-DM1 therapy in the clinic.
The preferred status of CLEOPATRA-like regimens in the first-line HER2-positive metastatic breast cancer setting has recently been challenged by antibody-drug conjugate regimens based on ado-trastuzumab emtansine (T-DM1).
