Maki Tanioka, MD, PhD, a postdoctoral research associate at UNC Lineberger Comprehensive Cancer Center, discusses an integrated analysis of multidimensional genomic data on the phase III CALGB 40601 (Alliance) study, which explored neoadjuvant weekly paclitaxel and trastuzumab (Herceptin) with or without lapatinib for patients with HER2-positive breast cancer,

Hyo Sook Han, MD, medical oncologist, Moffitt Cancer Center, discusses results of the phase II BROCADE trial, which evaluated the combination of the PARP inhibitor veliparib with carboplatin/paclitaxel in patients with <em>BRCA</em>-positive breast cancer.

William J. Gradishar, MD, deputy director of the Robert H. Lurie Comprehensive Cancer Center at Northwestern University Feinberg School of Medicine, discusses the takeaways from the TransATAC trial, which was a comprehensive comparison of prognostic signatures in breast cancer.

Findings from the first prospective, randomized clinical trial to evaluate modern scalp-cooling demonstrate that the system is safe and effective in reducing hair loss in women being treated with chemotherapy for their breast cancer, especially for those on taxane-based regimens.

An attempt to strengthen neoadjuvant treatment of patients with locally advanced HR-positive and HER2-positive breast cancer by adding estrogen deprivation therapy to a standard regimen failed to significantly improve response rates.

A biomarker analysis of participants in a phase II breast cancer trial demonstrated potential for identifying tumor markers to predict susceptibility to specific therapies.

Prophylactic treatment with the combination of loperamide and budesonide reduced the rate of grade &ge;3 diarrhea associated with neratinib to 15% compared with 39.9% observed in the ExteNET trial. The rate of all-grade diarrhea was 65% with the prophylactic regimen versus 95.4% in ExteNET, according to findings from the phase II CONTROL trial.
