Inflammation is a key risk factor and functional driver in the initiation and progression of prostate cancer (PCa). De-regulated cytokine and chemokine signaling facilitates critical communication between tumor cells and multiple cell lineages within the tumor microenvironment (TME). Historical attempts at using targeted approaches to disrupt inflammation have been disappointing, with sub-optimal or negligible clinical benefit. Our increased awareness of the myeloid infiltrate in supporting the acquisition of castrate resistance and underpinning the abject response of advanced PCa to immunotherapy has re-focused attention on improved strategies to disrupt these complex cytokine and chemokine signaling networks within the TME. These ongoing and prospective strategies are principally focused on employing cytokine-/chemokine-directed therapies in informed combination with androgen signaling inhibitors or immunotherapeutic agents and, increasingly, with due consideration of the genetic context of the tumor. The availability of molecular-targeted therapeutic agents directed against the critical signal transduction nodes activated by cytokine and chemokine signaling in tumor cells provides opportunities to reduce the impacts of biological redundancy. Precision-based trials that deploy this latest generation of cytokine- and chemokine-directed therapeutics, directed to enriched patient cohorts in a biologically informed and biomarker-guided manner, have the potential to diversify the armamentarium of agents that is required in order to transform long-term outcomes for a currently incurable and genetically heterogenous disease.
