High nerve density in breast cancer is associated with poor patient outcome.

ABSTRACT: Active crosstalk between the nervous system and breast cancer cells has been experimentally demonstrated in vitro and in animal models. However, low frequencies of peripheral nerve presence in human breast cancers reported in previous studies (~30% of cases) potentially negate a major role of the nervous system in breast cancer development and progression. This study aimed to clarify the incidence of nerves within human breast cancers and to delineate associations with clinicopathological features. Immunohistochemical staining was conducted in formalin-fixed paraffin-embedded breast cancer tissue sections using antibodies against the pan-neuronal markers protein gene product 9.5 and growth-associated protein 43, and the sympathetic nerve-specific marker tyrosine hydroxylase.
