About this trial

This is an interventional diagnostic trial for Thyroid Cancer

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patient is 18 years or older.
  • Signed Informed Consent.
  • Subject is diagnosed with a histologically confirmed differentiated thyroid carcinoma, that is considered RAI refractory. There is evidence of persisting or recurrent disease, based on serum thyroglobulin levels and/or medical imaging.
  • Subject should have a routine clinical 18F-FDG PET/CT performed within two months prior to the study scan.
  • Female patients should be either post-menopausal, surgically sterile, or using highly effective contraceptives (methods that can achieve a failure rate of less than 1%: combined hormonal contraception, progestogen-only hormonal contraception associated with inhibition of ovulation, intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomized partner, sexual abstinence).

Exclusion Criteria:

  • Patient has a known other active malignancy.
  • Subject is potentially pregnant (urinary test can be performed in case of doubt) or breastfeeding.
  • Patient is mentally or legally incapacitated.

Outcomes

Primary Outcome Measures

Demonstrate uptake of 18F-PSMA-11 in RAI-RTC
Confirmation in PET-scan that lesions in RAI-RTC show uptake of 18F-PSMA-11, above background activity in the bloodpool.

Secondary Outcome Measures

Perform a semi-quantitative analysis of radiotracer uptake in lesions.
Perform a lesion detection rate analysis on organ level.
Compare uptake of 18F-PSMA-11 in these patients to the uptake of 18F-FDG, on a lesion basis.
Evaluate the sufficiency of uptake of 18F-PSMA-11 to consider therapy with 177Lu-PSMA in a subset of patients
Compare the histological expression of PSMA on already available tumor samples with the uptake of lesions on PSMA PET.
Analyse the correlation between the serum level of PSMA and the uptake on PSMA PET
Compare the histological expression of PSMA on already available tumor samples with the serum level of PSMA.
