Correlation between Histopathological Prognostic Tumor Characteristics and [¹⁸F]FDG Uptake in Corresponding Metastases in Newly Diagnosed Metastatic Breast Cancer.

ABSTRACT:

Background

In metastatic breast cancer (MBC), [¹⁸F]fluorodeoxyglucose positron emission tomography/computed tomography ([¹⁸F]FDG-PET/CT) can be used for staging. We evaluated the correlation between BC histopathological characteristics and [¹⁸F]FDG uptake in corresponding metastases.

Patients and methods

Patients with non-rapidly progressive MBC of all subtypes prospectively underwent a baseline histological metastasis biopsy and [¹⁸F]FDG-PET. Biopsies were assessed for estrogen, progesterone, and human epidermal growth factor receptor 2 (ER, PR, HER2); Ki-67; and histological subtype. [¹⁸F]FDG uptake was expressed as maximum standardized uptake value (SUV_max) and results were expressed as geometric means.
