About the UKCTOCS

Back in 2001, researchers across the UK, led by University College London (UCL), began a clinical trial called the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) to evaluate whether multimodal screening (ROCA followed by transvaginal ultrasound scan of the ovaries) could detect ovarian cancer early enough to save lives.

The clinical trial required the help of 202,638 postmenopausal women from across the UK. The trial ran from 2001 and is still ongoing.
