Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To define the sensitivity of PET-DOPA for the detection of newly diagnosed untreated brain metastases (breast, lung, melanoma) on MRI measuring at least 5 mm in diameter.;Secondary Objective: a) Define the sensitivity of DOPA-PET according to the site of the primary tumor (lung, breast, melanoma) and its characteristics b) Characterize DOPA+ lesions in 20 and 30 minutes summed images analysis (SUVmax, SUVmean, tumor/brain background fixation ratio, tumor/striatum fixation ratio) c) Characterize DOPA+ lesions by dynamic image analysis (activity-time curves) d) For lesions operated within 2 months after the realization of the PET-DOPA, to evaluate the correlation between the various parameters of characterization of the F-DOPA fixation and the characteristics of the MC;Primary end point(s): number of metastases detected on PET-DOPA compared to the number of metastases + 5 mm detected on MRI;Timepoint(s) of evaluation of this end point: 1 day | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): a) The sensitivity of DOPA-PET is defined above (primary endpoint). Site-specific sensitivity will be calculated for 8 primary tumor categories: 3 for lung cancer (EGFR mutation or ALK rearrangement; PDL1+; others), 2 for melanoma (BRAF V600 mutation; others), 3 for breast cancer (triple negative; Her2+ RH-; others) b) Lesion characterization will be defined by SUVmax, SUVmean, tumor/brain background fixation ratio, tumor/striatum fixation ratio. c) Dynamic images are described with the analysis of activity-time curves (time to peak, slope of the curve from the 10th minute). d) The 8 categories mentioned above will be considered for the classification of the operated MC.;Timepoint(s) of evaluation of this end point: 2 months | — |
