Trastuzumab continues to show life for HER2-positve early stage breast cancer

After following breast cancer patients for an average of eight-plus years, researchers say that adding trastuzumab (Herceptin) to chemotherapy significantly improved the overall and disease-free survival of women with early stage HER2-positive breast cancer. They found that the use of trastuzumab produced a 37 percent improvement in survival and a 40 percent reduction in risk of cancer occurrence, compared to patients treated with chemotherapy alone. These findings demonstrate how important trastuzumab has been to the treatment of this form of breast cancer, says the study's lead author, Edith A. Perez, M.D., deputy director at large, Mayo Clinic Cancer Center and director of the Breast Cancer Translational Genomics Program at Mayo Clinic in Florida. Read more here.
