Computed tomography (CT) scans used in treatment response assessment in prostate cancer (PCa) patients are a useful tool for nutritional status evaluation. The aim of this study was to assess the nutritional status, including sarcopenia development based on CT scans, in PCa patients and its association with progression-free survival (PFS). Sixty-four PCa patients were included (group 1: 34 patients undergoing androgen deprivation therapy (ADT) with docetaxel due to newly diagnosed, hormone-sensitive, metastatic PCa and group 2: 30 patients with castration-resistant metastatic PCa continuing ADT therapy with enzalutamide or abiraterone acetate). Nutritional status was evaluated with anthropometrical parameters, Nutritional Risk Score (NRS), and CT scans at the L3 vertebrae. Survival analyses were performed. According to NRS, nutritional status was significantly related to PFS. In both groups, there was a significant reduction in muscle tissue (total muscle tissue and skeletal muscle index). A significant increase in the distribution of adipose tissue (subcutaneous fat, visceral fat, subcutaneous adipose tissue index, and visceral adipose tissue index) in group one was observed. Sarcopenia was diagnosed in patients but with no influence on PFS. Significant reduction in muscle mass and increase in fat mass was observed in patients treated for PCa with no impact on PFS. The NRS was related to PFS in PCa patients and associated with body composition, assessed by CT after the castration therapy. Long-term castration combined with abiraterone therapy with prednisone or enzalutamide significantly influenced muscle tissue and may lead to sarcopenia development.
Deprywacja androgenów (ADT-Androgen Deprivation Therapy) stanowi podstawę leczenia zaawansowanego raka gruczołu krokowego. Korzystny wpływ ADT na wyniki leczenia jest znany. W praktyce klinicznej obserwuje się również szereg powikłań związanych ze stosowaniem ADT, z których te związane z układem ruchu przebiegają stosunkowo dynamicznie i szybko pogarszają jakość życia pacjenta oraz jego codzienną aktywność. Aby im zapobiec lub zmniejszyć dynamikę ich rozwoju wskazana jest suplementacja witaminą D, wapnia, a przede wszystkim regularnie wykonywanie ćwiczeń fizycznych i modyfikacja sposobu żywienia. W pracy przedstawiono wpływ ADT na układ kostny i mięśniowy, metody jego oceny i zasady profilaktyki.
