Impact of Androgen Deprivation Therapy on Non-Alcoholic Fatty Liver Disease in Patients with Prostate Cancer: A CT Evaluation

Abstract
Purpose:The aim of this study was to investigate the influence of androgen deprivation therapy (ADT) on the progression of non-alcoholic fatty liver disease (NAFLD) in patients with prostate cancer (PCa) by evaluation of hepatic steatosis on computed tomography (CT).Methods:The study included 77 PCa patients who underwent abdominal CT at baseline and after 6 months of ADT. The degree of hepatic steatosis was evaluated according to the attenuation value for liver parenchyma (CTLP), the attenuation ratio for liver and spleen (LSratio), and the difference in attenuation between LS (LSdif). The associations between these 3 indices and various metabolic syndrome-related factors were analyzed.Results:The number of NAFLD patients increased from 9 (11.6%) at baseline to 16 (20.7%) after ADT. The CTLP, LSratio, and LSdif values were significantly lower after ADT than before (p< 0.05). There were significant correlations between the percent change in CTLP and the percent change in HbA(1c), between the percent change in LSratio and the percent change in abdominal circumference, and between the percent change in LSdif and the percent change in BMI.Conclusions:Six months of ADT was associated with significant progression of NAFLD in PCa patients. This progression was strongly correlated with changes in HbA(1c), abdominal circumference, and BMI.
