FESTA: 18F FES-PET/MRI for Tailoring Treatment of Luminal A and Lobular Breast Cancer
Study Details
Study Description
Brief Summary
Study hypothesis is that combining the advantages of hybrid PET/MRI and the high sensitivity/specificity of 16-alpha-18F-fluoro-17-beta-estradiol(FES), a radiolabeled form of estrogen binding to functionally active ER, the investigators could obtain a reliable, non-invasive, operator-independent, one-stage imaging method for staging LumA and ER-positive Lobular tumours.

Detailed Description
This is a single-centre prospective cohort study where patients with LumA and ER-positive Lob will be enrolled in 4 cohorts undergoing: primary surgery; induction endocrine therapy; neoadjuvant chemotherapy; systemic therapy for metastatic disease. For the purpose of the study an additional FES PET/MRI exam will be performed at baseline for local and systemic staging and a second exam after systemic therapy. Correlations between FES PET/MRI parameters and pathology, gene expression and FDG PET parameters, when available, will be investigated. Aim 1: Evaluating the performance of FES PET/MRI in axillary staging compared with axillary surgery. Aim 2: Evaluating potential correlations between changes in FES uptake and changes in proliferation index after 3 weeks of endocrine therapy before surgery. Aim 3: Evaluating the performance of FES PET/MRI in staging of patients undergoing systemic therapy in comparison with standard imaging. Additionally, biological determinants of tumor heterogeneity will be investigated.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Cohort A Candidates to surgery as first treatment regardless of cN ER+ Her2 negative BC with ki67>10% |
Drug: FES
16-alpha-18F-fluoro-17-beta-estradiol(FES) is a radiolabeled form of estrogen binding to functionally active ER which will be used as radiotracer for the PET/MRI exam
Procedure: PET/MRI A
An additional FES PET/MRI will be performed before surgery.
Genetic: Translational analysis
Selected cases of heterogeneous tumors on imaging will be also investigated on pathology, imaging, genomic and radiomic levels.
|
Experimental: Cohort B • ER positive BC treated with induction ET |
Drug: FES
16-alpha-18F-fluoro-17-beta-estradiol(FES) is a radiolabeled form of estrogen binding to functionally active ER which will be used as radiotracer for the PET/MRI exam
Procedure: PET/MRI B
Two additional PET/MRI will be performed before and after induction ET.
Genetic: Translational analysis
Selected cases of heterogeneous tumors on imaging will be also investigated on pathology, imaging, genomic and radiomic levels.
|
Experimental: Cohort C • Candidates to neoadjuvant chemotherapy |
Drug: FES
16-alpha-18F-fluoro-17-beta-estradiol(FES) is a radiolabeled form of estrogen binding to functionally active ER which will be used as radiotracer for the PET/MRI exam
Procedure: PET/MRI C
Two additional PET/MRI will be performed before and after two cycles of neoadjuvant chemotherapy.
Genetic: Translational analysis
Selected cases of heterogeneous tumors on imaging will be also investigated on pathology, imaging, genomic and radiomic levels.
|
Experimental: Cohort D • Metastatic LumA or ER-positive Lob BC, at first diagnosis or in progression |
Drug: FES
16-alpha-18F-fluoro-17-beta-estradiol(FES) is a radiolabeled form of estrogen binding to functionally active ER which will be used as radiotracer for the PET/MRI exam
Procedure: PET/MRI D
Two additional PET/MRI will be performed before and after two cycles of systemic therapy.
Genetic: Translational analysis
Selected cases of heterogeneous tumors on imaging will be also investigated on pathology, imaging, genomic and radiomic levels.

Outcome Measures
Primary Outcome Measures
- Sensitivity of FES PET/MRI in detecting macrometastatic axillary lymph nodes [Day 50]
Ability of FES PET/MRI to detect macrometastatic (tumor deposit>2mm) axillary lymph nodes in BC patients with LumA or Lob who are candidates to primary surgery.
Secondary Outcome Measures
- Changes in Standard Uptake Value (SUV) of FES in patients undergoing induction Endocrine Treatment (ET) [Day 0 and Day 50]
To investigate the potential correlation between Δ(FES SUV) and Δ(Ki-67 as proliferation index) after induction ET in luminal BC.
Other Outcome Measures
- FES PET/MRI sensitivity compared to that of standard imaging in patients undergoimg systemic therapy for neoadjuvant purposes or for metastatic disease. [Day 0]
Results from FES PET/MRI will be compared with those from standard imaging in terms of sensitivity and number of lesions detected.
- FES PET/MRI ability to predict tumor response or no response to therapy [Day 180]
Results of FES PET/MRI after two cycles of therapy will be compared to final pathology (cohort C) or standard imaging at 6 months (cohort D)
