Anesthetic technique and cancer surgery outcomes.

Julia Dubowitz, Jonathan Hiller, Bernhard Riedel,

<h4>Purpose of review</h4>Surgery remains integral to treating solid cancers. However, the surgical stress response, characterized by physiologic perturbation of the adrenergic, inflammatory, and immune systems, may promote procancerous pathways. Anesthetic technique per se may attenuate/enhance these pathways and thereby could be implicated in long-term cancer outcomes.<h4>Recent findings</h4>To date, clinical studies ... Read more >>
