Inflammation is now established as a hallmark of cancer. Cancer-associated fibroblasts (CAFs) have been established as a key component of the crosstalk between tumour cells and their microenvironment. Central to the role of CAFs in facilitating tumour growth, invasion, and metastasis is their ability to orchestrate tumour-related inflammation. CAFs and their soluble mediators provide multiple complex regulatory signals that modulate the trafficking, differentiation status, and function of inflammatory cells in the tumour microenvironment. This review focuses on pathways by which CAFs mediate tumour-promoting inflammation and modify the components of the inflammatory microenvironment that facilitate tumour initiation, progression, and metastasis.
