Both CA125 and HE4 tests contributed significantly to a risk prediction classifier combining serum markers with epidemiologic risk factors that may be useful in identifying post-menopausal women who would benefit from timely surgical intervention to prevent epithelial ovarian cancer, according to an analysis using 74,786 Women’s Health Initiative (WHI) Observational Study (OS) participants. Details included:
• In the WHI OS population, serum markers and epidemiologic factors classified 13% of women as elevated risk and identified 30% of ovarian cancers (HR=2.6).
• In the WHI Clinical Trial validation population, 8% of women were classified as elevated risk, identifying 31% of cancers (HR=4.6).
