In recent years, the infiltration of tumors by axons or nerves has been increasingly reported and has been linked to poor prognosis. This includes, among others, publications by Magnon et al (Science 341, 2013); and our own work (Faulkner et al., FASEB BioAdvances 2, 2020). Thus, recent investigations have been defying the old mechanistic, non-participating, view of the role of the nervous system in the tumor microenvironment. The “nerve-cancer connection” now is believed to encompass novel therapeutic targets already reported for breast, prostate and gastric cancers. However, the role of the autonomic nervous system in ovarian cancer development and progression remains unclear. We aimed to characterize this new component in ovarian tumors microenvironment. We identified the infiltration of peripheral axons in some ovarian tumors. In addition, ovarian tumors expressed neurotrophins, including nerve growth factor (NGF), in particular in the initial onset of the tumor. Our work expose the need to further comprehend the role of the nervous system in female cancers, namely in the unique microenvironments of ovarian tumors.
