Latest Trends in Treating Breast Cancer - 2011

Christine Wilson, cancer survivor, shares her experiences from the Abramson Cancer Center’s 2011 Update in Breast Cancer: Coverage of the American Society of Clinical Oncology (ASCO) Annual Meeting CME/CE Certified Course. The course is under the direction of Kevin Fox, MD, medical director of the Rena Rowan Breast Center. This is the first of four posts about the latest findings in treating breast cancer.

The summary of the latest news in breast cancer treatment was delivered in rapid-fire style at the Abramson Cancer Center’s 2011 Update in Breast Cancer ASCO summary course. Unfortunately, many of those attending the annual conference thought the news was "not as exciting as last year," because of the lack of any single, major breakthrough.

At the 2010 conference, Penn cancer researchers highlighted the promising results of targeted immunotherapy in treating metastatic breast cancer.

While there may have been no single big story, significant data were presented across the full platform of breast cancer-related topics: from prevention to neoadjuvant therapy and managing metastatic disease. Major emphasis was placed on improved understanding of the biology of breast cancer and the development of more targeted therapies tailored to match the specific genetic profiles of patients.

From the Headlines: FDA Approval for Bevacizumab

David M. Mintzer, MD

One issue that has been in the headlines during the past months is the status of FDA approval of bevacizumab (Avastin®) for first-line of treatment of HER2-negative metastatic breast cancer in combination with paclitaxel.  Bevacuzumab received fast track approval in 2008. Subsequent studies, including those presented at ASCO 2011, demonstrated modest improvements in progression-free survival, but none in overall survival or improvement in disease-related symptoms.  The down sides of the drug are its toxicity and high costs of administration.

Just hours after the update concluded, the Oncologic Drugs Advisory Committee voted 6-0 to withdraw FDA approval for bevacizumab for treating HER2-negative metastatic breast cancer. While the committee vote was unanimous, the hearing itself was marked by emotional pleas from breast cancer patients who believe they are benefitting from bevacizumab treatment.   The recommendation is not binding and a final decision is expected in September. It also does not affect insurance coverage or availability at this time, or the drug's approval for other cancer types.

"We know this drug has activity in some women," said David Mintzer, MD, clinical associate professor and chief of hematology/oncology, Pennsylvania Hospital. "We have all seen it and we know that activity stops when you stop giving the drug, but we just know now how to predict which women will get that benefit."

Abstracts can be found on the 2011 ASCO meeting website.
