Prognostic significance of basal 18F-FDG PET / CT maximum standardized uptake value in patients with metastatic renal cell carcinoma who were treated with sunitinib.

Purpose: To determine whether there is a relationship between maximum standardized uptake (SUVmax) value of basal 18-Fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG-PET/CT) that was performed before sunitinib treatment and treatment-related survival in patients with metastatic renal cell carcinoma (mRCC).

Methods: The data of 36 patients (female/male: 1/1, median age 57.36 years, range 31-74) were retrospectively analyzed in whom sunitinib treatment was started due to mRCC between 2008 and 2019 and who underwent basal 18F-FDG PET/CT examination before this treatment.
