E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate if 68Ga-PSMA PET/CT can detect prostate cancer recurrence, particularly at low PSA levels, and to identify if recurrence is confined to the prostatic bed, lymph nodes and/or bones. |
At undersøge om 68Ga-PSMA PET/CT kan detektere prostatacancer recidiv, specielt ved lave PSA værdier, og identificere om recidivet begrænset til prostatalejet, lymfeknuder og/eller knogler. |
|
E.2.2 | Secondary objectives of the trial |
To investigate if 68Ga-PSMA PET/CT is superior to anatomical MRI as well as diffusion-weighted (DW-) MRI in the detection of local recurrence, lymph node metastases and bone metastases in the axial skeleton in prostate cancer recurrence.
To assess if 68Ga-PSMA PET/CT is superior to 18F-fluoride PET/CT in the detection of bone metastases in patients with prostate cancer recurrence at whole body level.
To evaluate the added clinical value of 68Ga-PSMA PET/CT in terms of change of management by access to the results of 68Ga-PSMA PET/CT and anatomical MRI. A post-hoc analysis will be made with DW-MRI (which is read after the end of the study). |
At undersøge om 68Ga-PSMA PET/CT er bedre end anatomisk MR og diffusionsvægtet-MR til at detektere lokal recidiv, lymfeknude- og knoglemetastaser i det aksiale skelet ved prostatacancer recidiv.
At vurdere om 68Ga-PSMA PET/CT er bedre end 18F-fluorid PET/CT til at detektere knoglemetastaser i patienter med prostatacancer recidiv i en helkropsskanning.
At evaluere om 68Ga-PSMA PET/CT har en øget klinisk værdi i form af en ændret behandlingsstrategi ud fra resultaterne af 68Ga-PSMA PET/CT og anatomisk MR. En post hoc-analyse vil blive lavet med diffusionsvægtet MR. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
A subject is eligible for the study if all of the following apply:
Oral and written informed consent.
18 years and older.
The patient has undergone a curatively intended treatment for prostate cancer, which is considered to be radical at the end of the intervention/procedure.
Confirmed PCa recurrence (defined as PSA ≥ 0.2 ng/ml or more after radical prostatectomy or a rise of 2.0 ng/ml above the post-treatment PSA-nadir following radiation therapy).
Subject is able to lie still for the duration of the imaging procedure. |
Mundtlig og skriftlig informeret samtykke.
18 år og ældre.
Patienten har været igennem et forløb med kurativ intenderet behandling for prostatacancer, hvilket ansås som radikal efter interventionen/proceduren.
Bekræftet prostatacancer recidiv (defineret som PSA ≥ 0.2 ng/ml eller mere efter radikal prostatektomi eller stigning på 2.0 ng/ml over PSA-nadir efter stråleterapi).
Patienten skal kunne ligge stille under billeddannelsesproceduren. |
|
E.4 | Principal exclusion criteria |
History of another malignancy within the previous 5 years other than curatively treated non-melanoma skin cancer and prostate cancer.
History of allergic reactions attributed to compounds of 68Ga-PSMA radiotracer.
Subjects unable to undergo the PET/CT imaging procedure due to claustrophobia despite oral anxiolytics (institutional procedure).
Subjects weighing greater than 180 kilograms (weight limit for scanner table), or unable to fit within the imaging gantry.
Subjects with any medical condition or other circumstances (e.g. claustrophobia, unable to lie still, unable to comply with study procedures etc.) that, in the opinion of the Investigator, would significantly decrease the reliability of data, achievement of study objectives or completing the study.
If the patient refuses MRI or is not eligible (e.g. claustrophobia or other reasons as outlined in the ESUR guideline for MRI), the patient will be offered a diagnostic CT in combination with 68Ga-PSMA PET. If the patient refuses a diagnostic CT scan or allergic or ineligible for such procedure only a 68Ga-PSMA PET/low dose CT will be performed. Such patients will be assessed for secondary endpoints only. |
Anden cancersygdom inden for de seneste fem år bortset fra kurativ behandlet non-melanom hudcancer og prostatacancer.
Allergisk reaktion mod indholdsstoffer i 68Ga-PSMA sporstoffet.
Patienter ude at stand til at gennemføre 68Ga-PSMA PET/CT skanningen (fx pga. klaustrofobi til trods for behandling med oral anxiolytikum).
Patienter med kropsvægt over 180 kr (vægtbegrænsning for skanner) eller med andre begrænsninger i forhold til skannerens størrelse.
Patienter med en sygdomstilstand eller andre omstændigheder (fx klaustrofobi, manglende evne til at ligge stille eller lignende), der efter investigators opfattelse vil nedsætte datapålidelighed samt muligheden for at gennemføre studiet.
Hvis patienten nægter eller af andre årsager ikke er i stand til at gennemføre MR-skanningen, vil aptienten tilbydes en diagnostisk CT-skanning i kombination med 68Ga-PSMA PET-skanningen. Patienter, der nægter, er allergiske eller på anden måde uegnet til diagnostisk CT, vil få udført en 68Ga-PSMA PET i kombination med en lavdosis CT-skanning. Disse patienter vil kun blive evalueret i forhold til de sekundære endepunkter.
