Ovarian cancer screening does not appear to reduce risk of ovarian cancer death
Date:6/4/2011

In a clinical trial that included nearly 80,000 women, those who received ovarian cancer screening did not have a reduced risk of death from ovarian cancer compared to women who received usual care, but did have an increase in invasive medical procedures and associated harms as a result of being screened, according to a study in the June 8 issue of JAMA, a theme issue on cancer. The study is being published early online to coincide with its presentation at the American Society of Clinical Oncology 2011 Annual Meeting.

In the United States, ovarian cancer is among the 5 leading causes of cancer death in women. Most women with ovarian cancer are diagnosed with advanced stage disease, which has a 5-year survival of only 30 percent. The recognition that early detection of ovarian cancer may have the potential to improve prognosis prompted the development of randomized controlled trials to evaluate the efficacy of transvaginal ultrasound and serum cancer antigen 125 (CA-125) as screening tools to reduce ovarian cancer mortality, according to background information in the article.

Saundra S. Buys, M.D., of the University of Utah Health Sciences Center, Salt Lake City, and colleagues examined the ovarian cancer-specific mortality results from the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial to evaluate the effect of screening for ovarian cancer. The randomized controlled trial included 78,216 women, ages 55 to 74 years, assigned to undergo either annual screening (n = 39,105) or usual care (n = 39,111) at 10 screening centers across the United States between November 1993 and July 2001. The intervention group was offered annual screening with CA-125 for 6 years and transvaginal ultrasound for 4 years. Participants and their health care practitioners received the screening test results and managed evaluation of abnormal results. The usual care group was not offered annual screening with CA-125 for 6 years or transvagina
