Abstract

Prostate cancer (PC) is a leading cause of death in men. Inflammation is one of the initiating processes whereby cells are trafficked into the tumor microenvironment by specific cytokines termed chemokines. This recruitment is complex and involves diverse leukocyte subsets with procancer and anticancer functions. Chemokines promote/abrogate proliferation of cancerous cells, block/aid apoptosis, and are instrumental/detrimental in cancer cell migration required for metastasis. Chemokines guide the release/transport of immune cells that serve as chaperones at sites of inflammation, and after subsequent activation, they lead to an immune response. The variety of immune cells recruited at the site of tumor initiation possess unique functions, and the plethora of chemokines released by each cell derived from a progenitor cell activated under a defined set of conditions dictates its specific role in cancer progression/regression. Geographic consequences that govern the climate and endemic diseases, along with the associated evolutionary effects that at times protect populations from one disease, could lead to genetic variations that determine a role for ethnicity and race in PC risk and susceptibility. Dysregulated expression or an imbalance in the homeostatic mechanisms associated with chemokines is implicated in PC. This review discusses the role of inflammation and chemokines in PC.
