HER2+ Breast Cancer

Edith Perez, MD, the deputy director at large for the Mayo Clinic Cancer Center, compares the results of the BOLERO-1 and BOLERO-3 trials.

For additional insight on the CLEOPATRA trial and its implications for clinical practice, OncLive interviewed Sandra M. Swain, MD, Medical Director of the Washington Cancer Institute at MedStar Washington Hospital Center.

Frontline pertuzumab plus trastuzumab and docetaxel improved survival by nearly 16 months in metastatic HER2-positive breast cancer, according to results from the phase III CLEOPATRA study that are now published in The New England Journal of Medicine.

For further insight on the significance of palbociclib's approval, OncLive sat down with the lead investigator of PALOMA-1, Richard Finn, MD, from the Jonsson Comprehensive Cancer Center at UCLA.

Researchers will dissect topline results from the MARIANNE trial in the coming weeks in an effort to understand why T-DM1 (ado-trastuzumab emtansine; Kadcyla) failed to triumph as a first-line treatment in the metastatic setting for patients with advanced HER2-positive breast cancer despite the promise of earlier findings

Two HER2-targeting regimens anchored by T-DM1 (ado-trastuzumab emtansine; Kadcyla) failed to outperform the standard strategy in women with previously untreated advanced HER2-positive breast cancer in the MARIANNE trial, dealing a blow to efforts to move the drug into frontline settings.

When added to standard chemotherapy, trastuzumab not only dramatically improved disease-free survival rates for patients with metastatic disease, but also resulted in a clear survival advantage unprecedented for most treatments of metastatic breast cancer.
