“Don’t let it to air”: A cautionary tale of the potential consequences of surgery of residual cancer
BRAIN BEHAVIOR AND IMMUNITY(2023)
摘要
In this issue of the BBI, Haldar et al. demonstrate that major surgical stress from laparotomy caused a significant increase in post-operative metastatic burden in a mouse model of cancer. They identified this metastatic outbreak was driven by a novel mechanism of direct, surgery-induced activation of the primary tumour which, if left in situ, released pro-metastatic factors (IL-6, IL-8, and VEGF). Surgical stress induced significant changes in the transcriptional programming of the primary tumor, with marked activation of NF-κB and down-regulation of IRF-1. Pharmaceutical blockade of post-operative β-adrenergic and prostanoid signalling, by administration of propranolol and etodolac, prevented post-operative activation of the primary tumour and metastatic disease.
