Article Title: Inflammatory cytokines in robot-assisted thoracic surgery versus video-assisted thoracic surgery.
Abstract: Background: Cytokines play a crucial role in the inflammatory response and are essential modulators of injury repair mechanisms. While minimally invasive operations have been shown to induce lower levels of cytokines compared to open thoracotomy, the inflammatory cytokine profile difference between video-assisted (VATS) and robotic-assisted thoracic surgery (RATS) techniques has yet to be elucidated. Methods: In this prospective observational study of 45 patients undergoing RATS (n=30) or VATS (n=15) lung resection for malignancy, plasma levels of interleukin (IL)-1a, IL-1ß, IL-2, IL-4, IL-6, IL-8, IL-10, vascular endothelial growth factor (VEGF), interferon (IFN)-?, tumor necrosis factor (TNF)-a, monocyte chemo-attractant protein (MCP)-1, and endothelial growth factor (EGF) were measured before and after surgery via immunoassay. Results: Levels of IL-6 and MCP-1 were significantly higher in patients undergoing VATS than in patients undergoing RATS (P0.001 and P=0.005, respectively) 2 hours following surgery. MCP-1 levels were also found to be significantly higher in the VATS group (P0.001) 24 hours following surgery. IL-1a, IL-1ß, IL-2, IL-4, IL-8, IL-10, IFN-?, TNF-a, and EGF levels were not significantly different at any time-point comparing VATS to RATS. Conclusions: The VATS approach is associated with a more robust pro-inflammatory cytokine response through the upregulation of MCP-1 and IL-6 when compared to the RATS approach in patients undergoing anatomic lung resection. Further studies are necessary to validate the clinical significance of this finding.
