Dr. William M. Sikov, a medical oncologist in the Breast Health Center and associate director for clinical research in the Program in Women's Oncology at Women & Infants Hospital of Rhode Island, served as study chair and lead author for a recently-published major national study that could lead to improvements in outcomes for women with triple-negative breast cancer, an aggressive form of the disease that disproportionately affects younger women. The study, "Impact of the Addition of Carboplatin and/or Bevacizumab to Neoadjuvant Once-Per-Week Paclitaxel Followed by Dose-Dense Doxorubicin and Cyclophosphamide on Pathologic Complete Response Rates in Stage II to III Triple-Negative Breast Cancer: CALGB 40603 (Alliance)," was accepted as a rapid publication and published online on August 4, 2014 in the Journal of Clinical Oncology. The article will come out in print in September. Because of its rapid growth rate, many women with triple-negative breast cancer receive chemotherapy to try to shrink the cancer before undergoing surgery. With the standard treatment, the cancer is eliminated from the breast and lymph nodes in the armpit before surgery in about one third of women. This is referred to as a pathologic complete response (pCR). In patients who achieve pCR, the cancer is much less likely to come back, spread to other parts of the body, and cause the patient's death than if the cancer survives the chemotherapy. Dr. Sikov and his collaborators studied the addition of other drugs – carboplatin and/or bevacizumab – to the standard treatment regimen to see if they could increase response rates. More than 440 women from cancer centers across the country enrolled in this randomized clinical trial.
