PSMA-PET/CT to Assess the Expression of Specific Membrane Antigen (PSMA) in Patients With Progressive Triple-negative Breast Cancer. (PRISMA)
September 26, 2023 updated by: Jules Bordet Institute
PRISMA: A Single-centre, Prospective Phase II Imaging Study Using PSMA-PET/CT to Assess the Expression of Specific Membrane Antigen (PSMA) in Patients With Progressive Triple-negative Breast Cancer.
This is a descriptive, prospective, single centre study.
This study will assess PSMA expression via the uptake of radiolabelled PSMA-ligand using PET/CT imaging in mTNBC lesions pre-identified on 18F-FDG PET/CT in order to evaluate the feasibility of molecular radionuclide therapy in refractory mTNBC using the Lutetium-177 radiolabelled PSMA.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Assess PSMA expression in progressive metastatic TNBC patients
Time Frame: once at baseline prior to the start of the new anti cancer treatment
|
uptake of radiolabelled PSMA-ligand in patients with mTNBC on PET/CT images.
|
once at baseline prior to the start of the new anti cancer treatment
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Assess the concordance between lesions visualized on PSMA PET/CT and 18F-FDG PET/CT images (or brain MRI in case of brain metastases).
Time Frame: once at baseline prior to the start of the new anti cancer treatment
|
Matching between FDG and PSMA-labelled radiotracers uptake: on PSMA PET/CT and 18F-FDG PET/CT images, each lesion will be identified and faced with the other images.
Each imaging pair will be classified as complete match, partial match or no match between the different types of imaging
|
once at baseline prior to the start of the new anti cancer treatment
