Urine test could replace repeated scans for adrenal tumors
NCT ID NCT02324647
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 807 adults with adrenal tumors found by accident during scans for other reasons. Researchers compared the usual approach of repeat CT scans to a single urine steroid profile test to see which is more cost-effective for detecting cancer. The goal is to find a simpler, cheaper way to manage these common tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a simpler, more cost-effective way to diagnose adrenal tumors, reducing unnecessary scans.
- What could go wrong
- This is an observational study, not a treatment trial. The results may not change current practice if the new test is not accurate enough.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The research population consists of adult patients with a recently discovered adrenal incidentaloma who meet the selection criteria of SERENDIPITY. A total number of 1000 patients will be included. These subjects will be recruited from the group of patients in whom CT/MRI-scanning has been performed with visualization of the adrenal glands (i.e. CT/MRI scans of abdomen and/or chest, as the latter often include imaging of the upper abdominal region).

Inclusion Criteria: * discrete adrenal mass \> 1 cm in diameter incidentally discovered during CT/MRI-scanning, performed for reasons other than an evaluation for adrenal disease * detection CT/MRI-scan performed ≤ 4 months ago * age 18 years or older. Exclusion Criteria: * extra-adrenal malignancy (i.e. active or past medical history of malignancy, except for basal cell carcinoma) * radiologic diagnosis of simple cyst or bilateral adrenal masses * allergy to radiocontrast * renal insufficiency (i.e. eGFR \< 30 ml/min/1.73m2) * pregnancy * adrenal incidentaloma visible on previous (i.e. \> 4 months ago) CT/MRI-scan * inability to understand written Dutch.
