Blood test may spot ovarian cancer return before symptoms show
NCT ID NCT06588322
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a blood test can find genetic changes in tumor DNA that signal ovarian cancer is coming back. It involves 130 women with BRCA mutations who are taking a maintenance drug called Olaparib after initial treatment. The goal is to see if these blood tests can detect cancer progression earlier than standard scans.
