Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate parametric and conventional FES-PET/CT as methods of quantification of estrogen receptor (ER) expression in patients with disseminated BC;Secondary Objective: Not applicable;Primary end point(s): To examine the sensitivity measured by parametric FES-PET/CT with conventional FES PET/CT for detection of ER+ metastases in the liver;Timepoint(s) of evaluation of this end point: Ultimo 2021

Secondary

MeasureTime frame
Secondary end point(s): 1. Correlate ER expression in liver metastases, measured by FES-PET/CT, with Visiopharms H-score on IHC biopsies 2. Examine intra-individual heterogeneity of ER expression in liver metastases with FES PET/CT 3. Examine intra-individual heterogeneity in metastases in different tissues with FES PET/CT 4. Examine the ER expression heterogeneity between primary tumor and metastases with FES PET/CT 5. Correlate tumor blood flow, measured ny H215O-PET/CT, to the percentage of ER+ cell nucleus, measured by both FES-PET/CT and Visiopharm technology;Timepoint(s) of evaluation of this end point: Ultimo 2021
