title: Local anaesthetic use in cancer surgery and disease recurrence: role of voltage-gated sodium channels? British Journal of Anaesthesia, 2015; 113(6): 899-902, DOI 10.1093/bja/aeu221.
abstract: In the original article, under the "Declaration of Interests" section, the authors stated "none declared" since they had no direct interest in the use of local anaesthetics to treat cancer (the focus of the article being the beneficial use of local anaesthetics in cancer surgery). However, they do have a pending patent on blockers that specifically target the persistent current component of voltage-gated sodium channels, as anti-metastatic agents.
