Abstract
Sensory nerves form a crucial component of the tumor microenvironment (TME) that relays vital information to the central nervous system and modulates tumor progression via immunosurveillance. Afferent activity processed by the brain can sensitize brain circuitry and influence host behaviors. Peripheral sensory signaling (e.g., release of neuropeptides in the TME) can drive phenotypic changes in the tumor immune response, such as increased exhaustion markers and inhibited effector cell activity, which promote cancer progression. In this review we highlight the most recent evidence demonstrating the pivotal role of the sensory nervous system in cancer, with a focus on primary tumor pain, and we discuss the extent to which pain can influence cancer progression and treatment response, including immunotherapeutic strategies.
