Outcome Measures

Primary Outcomes (1)

  • 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.

    60 minutes +- 5 minutes after injection 18F-PSMA-11

Secondary Outcomes (7)

  • Perform a semi-quantitative analysis of radiotracer uptake in lesions.

    60 minutes +- 5 minutes after injection 18F-PSMA-11

  • Perform a lesion detection rate analysis on organ level.

    60 minutes +- 5 minutes after injection 18F-PSMA-11

  • Compare uptake of 18F-PSMA-11 in these patients to the uptake of 18F-FDG, on a lesion basis.

    60 minutes +- 5 minutes after injection 18F-PSMA-11

  • Evaluate the sufficiency of uptake of 18F-PSMA-11 to consider therapy with 177Lu-PSMA in a subset of patients

    60 minutes +- 5 minutes after injection 18F-PSMA-11

  • Compare the histological expression of PSMA on already available tumor samples with the uptake of lesions on PSMA PET.

    60 minutes +- 5 minutes after injection 18F-PSMA-11

  • +2 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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).

You may not qualify if:

  • 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.
