Why stopped (as posted): interim analysis showed incorrect use of simple rules
Summary
Brief summary (as posted)
This study is performed to compare the diagnostic performance and cost-effectiveness of different diagnostic methods for differentiating benign from malignant adnexal (ovary or Fallopian tube) masses: the Risk of Malignancy Index (RMI) will be compared with a two-step triage test called "simple ultrasound-based rules" supplemented -if necessary- with either subjective assessment by an expert sonographer or Diffusion Weighted - Magnetic Resonance Imaging (DW-MRI). The investigators will test the hypothesis that this two-step triage test will have better diagnostic accuracy than the RMI and therefore will improve the management of women with adnexal masses.

- label
- If simple rules are conclusive
- description
- All patients included will undergo an ultrasound scan in which both the RMI and simple ultrasound-based rules are applied. This scan will take place in the hospital of inclusion. For 80% of all patients, this will be the only intervention.

- OTHER
- label
- If simple rules are inconclusive
- description
- If the simple ultrasound-based rules, used in the first ultrasound scan, yield an inconclusive result (approx. 20% of all patients), patients are refered to the center hospital to undergo a second ultrasound (by an expert) and a DW-MRI scan. Furthermore, these group of patients will be asked to give an extra blood sample in order to perform translational research and validate new biomarkers in the diagnosis of ovarian cancer.
