UK study shows ultrasound screenings for ovarian cancer improve survival

A UK study published in Obstetrics & Gynecology shows that annual ultrasound screening of at-risk women with no symptoms increases the survival rates of women with type I and type II epithelial ovarian cancer.

The results come from the UK Markey Cancer Center’s Ovarian Cancer Screening Program, a 30-year study started in 1987 by gynecologic oncologist Dr. John van Nagell Jr. and the UK College of Medicine. The goal was to study whether transvaginal sonography (TVS) screening could be detect ovarian cancer earlier. Women who enrolled in the study were provided a free annual transvaginal ultrasound screening.

To date, more than 46,000 women have been given free screenings. To be eligible, women had to have no symptoms and either age 50 or older or age 25 or older with a documented family history of ovarian cancer in a close relative.

Through the study, 71 invasive epithelial ovarian cancers and 17 epithelial ovarian tumors of low malignant potential were found. The 5-, 10- and 20-year disease-specific survival rate of patients whose invasive ovarian cancers were detected by screening was more than 30 percent higher than unscreened women with ovarian cancer from the same geographic area treated at Markey. 

For the past 50 years, ovarian cancer has remained the leading cause of gynecologic cancer deaths in the United States. This year, more than 14,000 deaths from ovarian cancer will be reported in the United States, which makes it the fifth leading cause of female cancer mortality. When it is detected early, women often can be cured with existing treatment methods. However, most women have no symptoms until the disease has progressed to an advanced stage. As the disease progresses, survival rates drop sharply.

“While regular pelvic examination is important and can detect many other abnormalities, including cervical cancer, it is not effective in detecting ovarian cancer in its earliest and most treatable stages,” van Nagell said. “This study documents that TVS screening is safe and is associated with the earlier detection of ovarian cancer.”
