Ideal candidates are adults over 18 presenting with serious but nonspecific symptoms suggestive of cancer.

Probably not a fit

Patients who do not exhibit serious symptoms or have a known primary tumor may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The MEDECA study aims to improve early cancer diagnosis by identifying a multi-analyte blood test that can detect hidden cancers in patients with serious but nonspecific symptoms. It will involve 1500 patients referred to Danderyd Hospital's Diagnostic Center, where blood samples will be collected before a thorough cancer diagnostic work-up, including advanced imaging techniques. The study seeks to map occult cancer through biochemical analyses and collaboration with leading international scientists.

Why it matters

Potential benefit: If successful, this study could lead to earlier detection of cancer, significantly improving patient outcomes.

How similar studies have gone: Other studies have shown promise in using blood tests for early cancer detection, but this specific approach is novel.
