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

  1. 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

  1. 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

  1. 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.

  2. 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)
