Research Team Shows No Benefit to Weekly Treatments for Ovarian Cancer
Release Date: 04/13/2016
An article published in a recent issue of the New England Journal of Medicine evaluated the role of administering a commonly used chemotherapy drug for ovarian cancer on a weekly basis as compared to every three weeks in the hopes of improving survival without disease progression.
Contrary to a previously published clinical trial from the Japanese Gynecologic Oncology Group, no additional benefit was seen from weekly administration. However, the lack of improvement may have been caused by the addition of a third drug, Bevacizumab, to the regimen. In those patients who did not opt to receive Bevacizumab, there appeared to be improvement in survival for the weekly regimen.
The team of researchers – which includes Paul DiSilvestro, MD, head of research with the Program in Women’s Oncology at Women & Infants Hospital and professor of obstetrics and gynecology at The Warren Alpert Medical School of Brown University – are part of the Gynecologic Oncology Group (GOG). The study is named “Weekly vs. Every Three Weeks Paclitaxel and Carboplatin for Ovarian Cancer.”
“We knew that a dose-dense weekly schedule of the drug paclitaxel and the delivery of a second drug carboplatin every three weeks has been effective in treating women with ovarian cancer,” Dr. DiSilvestro notes. “This study was an effort to confirm those results seen in the Japanese study. Many oncologists do not use Bevacizumab in front-line treatment and support continued use of the weekly regimen.”
There were drawbacks to the weekly treatments, however. While fewer women receiving their medication weekly suffered from low white blood cell counts, there was a higher incidence of neuropathy. Cost is also a factor.
The Women & Infants research team concluded that there needs to be more effectiveness studies into the combination and timing of medications for women with ovarian cancer.
Dr. DiSilvestro is accepting new patients. For more information, call (401) 453-7520.
