Abstract

Mounting evidence indicates that the nervous system plays a central role in cancer pathogenesis. In turn, cancers and cancer therapies can alter nervous system form and function. This Commentary seeks to describe the burgeoning field of "cancer neuroscience" and encourage multidisciplinary collaboration for the study of cancer-nervous system interactions.

Interactions between the nervous system and cancer.
A) Synaptic communication between neurons and brain cancer cells (e.g. malignant glioma, red) can regulate cancer growth through neurotransmitter and voltage-regulated mechanisms. Whether synaptic interactions occur between peripheral nervous system axons and cancer cells outside of the central nervous system remains to be explored. B) Paracrine signaling between neurons/nerves (grey) and cancer cells (red), for example neuronal activity-dependent release of neurotransmitters or growth factors, regulates cancer growth in a wide range of tissues. The influence of neurons on malignant cells may be direct or may be mediated through effects on other cell types (green) in the tumor microenvironment. Cancer-derived paracrine factors remodel the nervous system to promote increased neural activity in the tumor microenvironment. C) Circulating factors from cancer (red) can influence nervous system (grey) functions such as sleep, while the nervous system can influence cancer progression through circulating factors such as hormones and progenitor cells or through altered immune system (blue) function. D) Cancer therapies frequently cause nervous system toxicities, from peripheral neuropathy to cognitive impairment. Molecular and cellular mechanisms of nervous system toxicities and the putative role that such disruption in nervous system function may play in cancer treatment efficacy require further study.
