Treatment for Advanced Ovarian Cancer Effective
Synopsis: New treatment regimen shown effective against advanced ovarian cancer. New treatment regimen shown effective against advanced ovarian cancer.
Main DigestNew treatment regimen shown effective against advanced ovarian cancer.
Newly reported results from a major clinical trial show that adding bevacizumab (Avastin) to standard front-line chemotherapy for women with advanced ovarian cancer and then continuing a maintenance dose of the drug afterwards significantly extends progression-free survival. Women receiving the new treatment regimen saw no worsening of their disease for 14.1 months, compared to 10.3 months for women receiving standard therapy.
The international, multi-center, randomized, double-blind, placebo-controlled Phase III clinical trial was conducted by a network of researchers known as the Gynecologic Oncology Group (GOG) and sponsored by the U.S. National Cancer Institute. The trial results were presented at the 46th Annual Meeting of the American Society of Clinical Oncology (ASCO).
The trial marked the first time a molecularly targeted agent has been part of a validated strategy for treating advanced ovarian cancer. It was also the first time a maintenance dosing approach involving any therapy has been outlined for the disease. Additionally, ongoing analysis of the trial data may offer insights into genetically defined subgroups of patients who benefited more than others, pointing to the possibility of more personalized, even more effective treatment for ovarian cancer in the future.
"Ovarian cancer remains one of the most deadly cancers in women, so this clinical advance is particularly welcome," says Robert A. Burger, M.D., lead investigator on the GOG trial and director of the Women's Cancer Center at Fox Chase Cancer Center. "Before this, we could treat ovarian cancer patients only with surgery and chemotherapy involving relatively toxic agents. Now, we have a third type of more targeted therapy to offer these patients, potentially opening the way to even greater progress in years to come."
According to the American Cancer Society, approximately 22,000 new cases of ovarian cancer will be diagnosed this year, and about 15,000 women will die from their disease. Ovarian cancer is the eighth most common cancer among women, excluding non-melanoma skin cancers. It ranks fifth in cancer deaths among women, accounting for more deaths than any other cancer of the female reproductive system.
The trial, dubbed GOG-0218, enrolled 1,873 previously untreated women with advanced disease from 336 sites in four countries (U.S., Canada, South Korea, and Japan). The women were randomly assigned to one of three treatment protocols: standard chemotherapy (carboplatin and paclitaxel) plus placebo, followed by placebo maintenance for an up to 10 additional months; standard chemotherapy plus bevacizumab followed by placebo maintenance; and standard chemotherapy plus bevacizumab followed by bevacizumab maintenance. The type and frequency of bevacizumab-associated side effects were similar to those seen in previous cancer studies involving the drug.
Bevacizumab, a humanized monoclonal antibody, is an angiogenesis inhibitor, meaning that the drug limits tumor growth by interfering with the formation of new blood vessels to supply the tumor with needed nutrients. It acts by inhibiting the function of a naturally occurring protein called vascular endothelial growth factor, or VEGF, which is overproduced in many cancers and stimulates new blood vessel formation.
Burger is the lead investigator on the GOG-0218 study presented at ASCO, which was launched in September 2005 while he was at the University of California, Irvine; he moved to Fox Chase Cancer Center in September 2008. The co-authors on the study are: M.F. Brady, Roswell Park Cancer Institute; M.A. Bookman, University of Arizona Cancer Center; J.L. Walker, University of Oklahoma Health Sciences Center; H.D. Homesley, Brody School of Medicine; J. Fowler, James Cancer Hospital at the Ohio State University; B.J. Monk, University of California, Irvine, Medical Center; B.E. Greer, Seattle Cancer Care Alliance; M. Boente, Minnesota Oncology and Hematology; and S.X. Liang, State University of New York at Stony Brook.
Fox Chase Cancer Center is one of the leading cancer research and treatment centers in the United States. Founded in 1904 in Philadelphia as one of the nation's first cancer hospitals, Fox Chase was also among the first institutions to be designated a National Cancer Institute Comprehensive Cancer Center in 1974. Fox Chase researchers have won the highest awards in their fields, including two Nobel Prizes. Fox Chase physicians are also routinely recognized in national rankings, and the Center's nursing program has received the Magnet status for excellence three consecutive times. Today, Fox Chase conducts a broad array of nationally competitive basic, translational, and clinical research, with specialized programs in risk assessment, women's cancers, and personalized medicine, among others.
