Molecular signal in blood helps detect early risk for ovarian cancer, study finds

Researchers at Hoag Family Cancer Institute discovered an RNA molecule called Tu-Stroma that, when measured in blood, detected precancerous ovarian lesions (STIC) in 92.3% of affected women and correctly identified 98.2% of healthy women.

The study was published in Nature Medicine and tested on blood samples; effectiveness in routine clinical practice remains to be demonstrated. For women at high genetic risk, approximately 72% of positive results would be accurate.
