Abstract (original English)

Prostate cancer (PCa) is the most prevalent cancer among men, highlighting the urgent need for innovative treatment strategies. The periprostatic adipose tissue (PPAT) plays a crucial role in the PCa tumor microenvironment, with direct crosstalk between PPAT and PCa cells, particularly in advanced stages with extraprostatic extension-a feature linked to poor prognosis. Owing to their migratory capacity, adipose stem cells (ASCs) are promising in regenerative medicine and play a key role in tissue engineering and cancer research. These findings offer potential for novel approaches in targeted drug delivery and gene therapy for PCa. While ASCs within PPAT influence the tumor stroma, the mechanisms behind their interactions with PCa cells are not fully understood, with studies reporting both inhibitory and promoting effects on cancer progression. The adipose tissue secretome, including PPAT-ASC exosomal proteins, mediates communication between PPAT and PCa cells, with exosomal dysregulation observed in stage T3 PCa. This dysregulation implicates key cancer pathways such as integrin-mediated cell interactions, epithelialmesenchymal transition, and mRNA stability regulation. Although ASCs show promise as therapeutic carriers, their use is complicated by the need to prevent unwanted interactions with cancer cells. Moreover, environmental contaminants such as endocrine disruptors can
