Dr Harold J. Burstein, from the Dana-Farber Cancer Institute in Boston, Massachusetts, reports on important abstracts in the management of metastatic breast cancer from the 2022 American Society of Clinical Oncology (ASCO) annual meeting.
Dr Burstein first highlights results from the NRG-BR002 trial, a randomized phase 2 study comparing standard therapy vs standard therapy in combination with focal stereotactic radiation treatment for oligometastatic disease in up to four sites. Investigators reported no impact on progression-free or overall survival.
Exciting results from the DESTINY-Breast04 trial were a "showstopper," according to Dr Burstein. Investigators reported prolonged progression-free survival and overall survival in patients with HER2-low unresectable and/or metastatic disease with the use of the antibody-drug conjugate trastuzumab deruxtecan compared with physicians' choice of standard single-agent chemotherapy, advancing a new treatment option for the large subset of patients with HER2-low disease.
Next, Dr Burstein discusses results from the TROPiCS-02 trial, which compared another antibody-drug conjugate, sacituzumab govitecan, with standard chemotherapy in patients with ER+/HER- breast cancer. A statistically significant benefit was reported, although the progression-free survival at just 6 weeks was relatively modest.
Finally, Dr Burstein reports on interesting data from the MAINTAIN study, a phase 2 randomized trial looking at maintenance CDK4/6 inhibition after progression on initial treatment. Results suggest that switching endocrine therapy and continuing treatment with CDK4/6 inhibitor ribociclib beyond progression may be of clinical value to patients.
