[Perioperative tumour dissemination. 1. Influence of perioperative factors].
There has been growing concern in the last few years on the effect of anaesthetic drugs used during oncological surgery could have on tumour progression in the long-term, as well as the influence of other perioperative factors. Although much of the available data has weak evidence, the role of the surgery itself, pain, transfusion of blood derivatives, etc., have been assessed in several studies. How some substances used during the anaesthetic process can influence tumour immune surveillance, cell proliferation or tumour angiogenesis processes have been observed in laboratory studies. The possible relevance of the anaesthetic technique used as regards the long-term tumour progression and survival is still to be determined. However, based on retrospective studies, it seems that those anaesthetic techniques combined with the use of regional anaesthesia and analgesia could be beneficial compared to those that are maintained on opioid use. Further research should help to elucidate the long-term clinical relevance of the perioperative procedures, including the anaesthetic, during oncological surgery.
