Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: - To compare 68Ga-PSMA-617 uptakes values between prostatic sextants for which histologic examination reveal a Gleason score 6, those for which histologic examination reveal a Gleason score 7(3+4) (favourable intermediate risk), for which histologic examination reveal a Gleason score 7(4+3) (unfavourable intermediate risk) and those for which histologic examination reveal a Gleason score 8 or more - To compare 68Ga-RM2 uptakes values between prostatic sextants for which histologic examination reveal a Gleason score 6, those for which histologic examination reveal a Gleason score 3+4 (favourable intermediate risk), those for which histologic examination reveal a Gleason score 4+3 (unfavourable intermediate risk) and for which histologic examination reveal a Gleason score 8 or more ;Secondary Objective: • To compare 68Ga-PSMA-617 and 68Ga-RM2-uptakes between prostatic sextants for which histologic examinations reveal a Gleason score 6 • To compare 68Ga-PSMA-617 and 68Ga-RM2-uptakes between prostatic sextants for which histologic examinations reveal a Gleason score 7(3+4) • To compare 68Ga-PSMA-617 and 68Ga-RM2-uptakes between prostatic sextants for which histologic examinations reveal a Gleason score 7(4+3) • To compare 68Ga-PSMA-617 and 68Ga-RM2-uptakes between prostatic sextants for which histologic examinations reveal a Gleason score 8 or more • To evaluate and compare 68Ga-PSMA-617 and 68Ga-RM2-uptakes in metastatic nodes • To estimate the association between 68Ga-PSMA-617 and 68Ga-RM2-uptakes and Gleason score both in vivo and ex vivo • To compare 68Ga-PSMA-617 uptake in healthy and pathological tissues at 1h and 2h after injection • To compare 68Ga-RM2 uptake in healthy and pathological tissues at 1h and 2h after injection • To compare micro-imaging data to immunohistochemistry ;Primary end point(s): Median Standardized Uptake Value (SUV) of 68Ga-PSMA-617 and 68Ga-RM2 ;Timepoint(s) of evaluation of this end point: Inclusion visit (V1) Follow up | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Gleason score - Micro-imaging data : receptor density Bmax and local radioactive concentration expressed in cpm - Ex vivo immunohistochemistry data: Immunoreactive score (IRS) considering both percentage of stained cells and staining intensity. ;Timepoint(s) of evaluation of this end point: Inclusion visit (V1) Follow up visit (V2) Last visit (V3 - Prostatectomy) | — |
