Genetic and ancestral factors, molecular pathways involving androgen and non-androgen receptor signalling, inflammation, epigenetics, the tumour microenvironment and tumour metabolism are posited as biological factors that potentially contribute to racial disparities in Black men with prostate cancer.

Sexual interactions between members of the same sex are common but the reasons for these behaviours are not always clear. Results from a study across mammals suggest that increased same-sex behaviour evolved with sociality and might reduce conflict, although increased male–male sexual interactions are associated with increased adult killing.

Senescent stromal fibroblasts exhibit a senescence-associated secretory phenotype, which can promote prostate cancer development, progression and resistance to therapy. Targeting senescent cells via senotherapeutics might be an attractive preventive or therapeutic option for prostate cancer.

Here, the authors describe the history of the efforts to expand knowledge of Wilms tumour biology, genetics, embryonal origin and associated syndromic and familial conditions, and to clinically apply prognostic biomarkers and development of preclinical models.
