Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The study design is based on a co-primary endpoint for the evaluation of diagnostic performance in terms of sensitivity and specificity of 64Cu PET/CT compared to 18F-choline PET/CT. The assessment of sensitivity and specificity for the co-primary endpoint is expressed on a patient basis, in relation to the whole individual.;Secondary Objective: 1. to evaluate the higher diagnostic accuracy of 64CuCl2 PET/CT in the identification of metastases compared to 18F-choline PET/CT (diagnostic performance); 2. estimate the sensitivity and specificity between the two PET/CT scans (64CuCl2 and 18F choline) on a regional basis (chest, abdomen, pelvis) and on a lesion basis (bone, lymph nodes and visceral) (diagnostic performance); 3. Correlate the sensitivity of 64CuCl2 PET/CT and 18F choline PET/CT to different PSA levels (diagnostic performance);;Primary end point(s): To evaluate the diagnostic performance in terms of sensitivity and specificity of 64Cu PET/CT compared to 18F-choline PET/CT on a patient basis, in relation to the whole individual. In particular, 18F-choline PET/CT and 64CuCl2 PET/CT will be evaluated as positive (PET+) in case of evidence of pathological focal uptake at site(s) compatible with metastases (bone, lymph node and visceral; they will otherwise be judged negative (PET-) when no pathological focal uptake is detectable.;Timepoint(s) of evaluation of this end point: at the end of trial | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1. The diagnostic accuracy of the two PET/CT scans (64Cu and 18F-choline) will be assessed by area under the ROC curve (AUC) and the difference of the curve between the two methods will be assessed, 2. Lesion-based and region-based sensitivity and specificity will be analyzed by aggregation according to body region (thorax, abdomen, pelvis) and anatomical-pathological character of lesions (bone, lymph nodes, visceral) 3. 64Cu PET and 18F-choline sensitivity will be correlated with PSA levels and calculated as per the primary objective, 4. Patients will be classified into non-metastatic, oligometastatic and multimetastatic with both PET/CT. (oligometastatic will be defined as a patient with a maximum number of three metastases), 5. In each patient, the different impact determined by the two PETs on decision thinking (impact of the test compared to the pre-test probability) will be evaluated with calculation of positive and negative predictive values, 6. In each patient, the impact determined by the 64Cu PET/CT on the clinical outcome will be evaluated by means of the patient's follow-up data and in particular the consequences of a misdiagnosis (delay of treatment or unnecessary interventions) will be evaluated, 7. The inter-observer reproducibility of 64CuCl2 and 18F-FCH PET/CT will be evaluated.;Timepoint(s) of evaluation of this end point: at the end of trial | — |
