Theranostic PET for target validation and tumor detection in solid cancers

Official title: Theranostic PET for Target Validation and Tumor Detection

Run by University Hospital, Essen · NCT07664410 · Data updated 2026-11-12

This is an observational effort to see how theranostic PET scans reflect tumor targets and help with staging, restaging, and treatment planning for adults with solid cancers.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with solid malignancies who are scheduled for theranostic PET as part of routine staging or restaging.

Probably not a fit

Patients whose tumors do not express targets detectable by theranostic PET or whose imaging does not alter management may see no direct benefit.

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

What this trial studies

Patients undergoing theranostic PET scans as part of routine cancer care are enrolled to collect data on how well PET tracer uptake matches molecular target expression, how often tumor regions show uptake, and how PET findings influence clinical decisions. The study analyzes diagnostic performance metrics such as sensitivity, specificity, PPV, and detection rate, using both PET/CT and PET/MRI with novel or established tracers. Primary endpoint examines the association between PET uptake intensity and histopathologic target expression. Secondary endpoints cover per-lesion uptake, regional and patient-level detection, and changes in staging or prognosis.

Why it matters

Potential benefit: If successful, findings could improve how PET findings guide personalized therapy and staging decisions in solid cancers.

How similar studies have gone: Previous studies in theranostic imaging have shown potential for target-guided planning, but the extent of correlation with histopathology across tumor types remains variable.
