Researchers Unveil Standard Treatment For Advanced Ovarian Cancer

Physicians at St. Joseph’s Hospital and Medical Center have unveiled the standard treatment for advanced ovarian cancer. Dr Bradley J. Monk, and researchers at 12 other medical facilities around the nation directed the research.

The //featured research titled "Every-3-Week vs. Weekly Paclitaxel and Carboplatin for Ovarian Cancer" unveils that the standard front-line treatment for advanced ovarian cancer should either be every three-week chemotherapy with carboplatin, paclitaxel plus bevacizumab (an antibody than inhibits blood vessels from feeding the cancer) or every three-week chemotherapy with carboplatin and weekly dose intense paclitaxel. The latter does not involve expensive bevacizumab known as Avastin but is more inconvenient.

Ovarian Cancer | Cancer in the Ovaries - Causes, Symptoms, Treatment & Prevention
Ovarian cancer affects both the ovaries and is referred to as the 'silent killer' as the symptoms go unnoticed until the disease advances.

‘Ovarian cancer is the fifth most common cause of cancer-related death in women. The American Cancer Society estimates that in 2016, about 22,280 new cases of ovarian cancer will be diagnosed.’

"This supports the use of weekly chemotherapy without bevacizumab in treating advanced ovarian cancer," says Dr. Monk who is Director, Division of Gynecologic Oncology Vice Chair, Department of Obstetrics and Gynecology University of Arizona Cancer Center at St. Joseph's Hospital and senior author of the publication.

The research was funded by NRG Oncology (formerly the Gynecologic Oncocolgy Group), which is part of the National Institutes of Health and enrolled patients at cancer centers around the country. Many women with ovarian cancer at the University of Arizona Cancer Center at St. Joseph's Hospital participated in this study.

Importantly, this study did not investigate intraperitoneal chemotherapy (IP) where the chemotherapy is infused directly into the belly. Many believe that the regimen of dose intense weekly chemotherapy supported by the current publication capitalizes on the same key components of IP chemotherapy namely higher doses and weekly administration. However, the intravenous recipe supported by this publication does did not show the intense side effects seen with IP treatments.

Does Talcum Powder Pose a Risk for Ovarian Cancer?
Ovarian cancer is the fifth most common cancer among women, accounting for more deaths than any other cancer of the female reproductive system.

This advance is only a small step forward as newer appraises to ovarian cancer are being developed at University of Arizona Cancer Center at St. Joseph's Hospital. For example, doctors are studying a unique class of drugs called PARP inhibitors as well as immunotherapy. The latter uses recently discovered approaches to re-programming a woman's immune system to recognize and fight her ovarian cancer. Such drugs have recently been FDA approved to treat lung cancer and melanoma.

The study is published in New England Journal of Medicine.
