ScienceDaily (Jan. 10, 2006) — According to a study published in the January 5 issue of the New England Journal of Medicine, women with Stage III ovarian cancer given a combination of intravenous (IV) and intra-abdominal chemotherapy, following the successful surgical removal of tumors, experienced a median survival time 16 months longer than women who received IV chemotherapy alone.

Intra-abdominal chemotherapy, also known as intraperitoneal (IP) chemotherapy, involves the delivery of anticancer drugs directly into the abdomen. This type of chemotherapy administration is underutilized, but significant evidence from this new study confirms the survival benefit of IP chemotherapy for most women with advanced ovarian cancer.

The study, conducted by Deborah K. Armstrong, MD, an assistant professor at the Johns Hopkins Kimmel Cancer Center in Baltimore, Maryland, and her colleagues, builds upon evidence from eight other clinical trials -- including those conducted at Memorial Sloan-Kettering Cancer Center (MSKCC) -- showing an overall survival period of approximately one year for women treated with IP chemotherapy after "optimal debulking" -- surgery to remove most, if not all, of the cancer in the abdomen.

Based on this overwhelming evidence, the National Cancer Institute (NCI) will issue a clinical announcement on January 5 encouraging the administration of a combination of IV and IP chemotherapy to treat women with advanced ovarian cancer, who have undergone optimal surgical debulking.

After pioneering the first clinical trials of IP chemotherapy in the late 1980s, MSKCC is one of the most experienced centers with the largest volume of patients who have undergone the procedure. The Center has been using IP chemotherapy as a standard of care based on Dr. Armstrong's presentation at the American Society of Clinical Oncology's annual meeting in May 2005 and research conducted at MSKCC.
