E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate the sensitivity and specificity of 68Ga-PSMA PET/CT versus MRI/CT against the reference test (lymphadenectomy) for the detection of lymph node metastasis on a patient-level in patients with locally advanced PCa. |
At undersøge sensitivitet og specificitet af 68Ga-PSMA PET/CT versus MR/CT i forhold til referencetesten (lymphadenektomi) til at detektere lymfeknudemetastaser på patient-basis i patienter med local avanceret prostatacancer. |
|
E.2.2 | Secondary objectives of the trial |
To investigate the sensitivity and specificity of 68Ga-PSMA PET/CT versus MRI/CT against the reference test (lymphadenectomy) for the detection of lymph node metastasis on a lesional (node-region) level.
To investigate observer agreement in the assessment of 68Ga-PSMA PET/CT for local prostate involvement, nodal spread and bone metastasis if present.
To assess the presence, if any, of bone metastasis in the axial skeleton as demonstrated by 68Ga-PSMA PET/CT and DW-MRI in patients with a metastasis-free bone scintigraphy performed as part of the standard staging procedure. |
At undersøge sensitivitet og specificitet af 68Ga-PSMA PET/CT versus MR/CT i forhold til referencetesten (lymphadenektomi) til at detektere lymfeknudemetastaser på læsion-basis (lymfeknude region).
At undersøge observatør overensstemmelse i vurderingen af 68Ga-PSMA PET/CT til lokal prostatainvolvering, lymfeknude- og knoglemetastaser, hvis muligt.
At undersøge mulig tilstedeværelse af knoglemetastaser i det aksiale skelet ved 68Ga-PSMA PET/CT og diffusionvægtet MR hos patienter med metastase-fri knogleskintigrafi udført som del af normal procedure. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Oral and written informed consent.
18 years and older.
Histological confirmed adenocarcinoma of the prostate.
Routine bone scintigraphy without metastasis.
Referred for lymph node staging as standard clinical practice - either concurrent with surgical removal of the prostate (radical prostatectomy) or prior to curative (radiation therapy) or palliative (hormonal) treatment. |
Mundtlig og skriftlig informeret samtykke.
18 år og ældre.
Histologisk bekræftet prostataadenokarcinom.
Rutine knogleskintigrafi uden metastaser.
Henvist til lymphadenektomi som del af standard klinisk praksis - enten samtidig med operativ fjernelse af prostata (radikal prostatektomi) eller før kurativ (strålebehandling) eller palliativ (hormon) behandling. |
|
E.4 | Principal exclusion criteria |
Prior or current therapy for prostate cancer.
History of another malignancy within the previous 5 years other than curatively treated non-melanoma skin cancer.
History of allergic reactions attributed to compounds of 68Ga-PSMA radiotracer.
Subjects unable to undergo 68Ga PSMA PET/CT imaging procedure (e.g. claustrophobia despite oral anxiolytics).
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 (known with 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. |
Tidlig eller nuværende behandling for prostatacancer.
Anden cancersygdom inden for de seneste fem år bortset fra kurativ behandlet non-melanom hudcancer.
Allergisk reaktion mod indholdstoffer i 68Ga-PSMA sporstoffet.
Patienter ude af stand til at gennemføre 68Ga-PSMA PET/CT skanningen (fx klaustrofobi til trods for behandling med oral anxiolytikum).
Patienter med kropsvægt over 180 kg (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 og 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 patienten 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. |
