Advanced Breast Cancer Slowed with Avastin Combo (CME/CE)

Excerpt:

“Adding bevacizumab (Avastin) to letrozole (Femara) improved progression-free survival (PFS) in estrogen receptor-positive metastatic breast cancer (ER+MBC) but not other outcomes, an open-label, multicenter phase III trial showed.

“While median PFS increased by 4.6 months in patients who received combined therapy versus letrozole alone, there was no significant difference in overall survival (hazard ratio 0.87; 95% CI 0.65-1.18; P=0.188), Maura N. Dickler, MD, of Memorial Sloan Kettering Cancer Center in New York City, and colleagues reported online in the Journal of Clinical Oncology.

“In addition, there was a marked increase in grade 3 to 4 toxicities, particularly hypertension (24% versus 2%) and proteinuria (11% versus 0%), the researchers said, emphasizing that the role of bevacizumab in this setting will need to be clarified with research on predictive markers.”
