Abstract
PURPOSE
We examined whether redox balance during the perioperative period is associated with long-term survival of patients after undergoing lung resection.
METHODS
Patients who underwent surgery for lung cancer from January to June 2013 at our institution were investigated. Serum was collected during the operation, and on postoperative day (POD) 3 and 7, and the levels of derivatives of reactive oxygen metabolites (d-ROMs) and biologic antioxidant potential (BAP) were measured.
RESULTS
In all, 21 patients (69 ± 7 years old) were enrolled, of whom 9 underwent video-assisted thoracoscopic surgery. Comorbidities in the patients included chronic obstructive pulmonary disease in eight and idiopathic pulmonary fibrosis in five. d-ROM values on POD 3 and 7 were significantly increased as compared to those obtained during the operation (p <0.001), whereas BAP did not change after surgery. Patients with a value below a d-ROM cutoff value of 327 during the operation showed significantly superior 3-year overall survival as compared to those with a value above the cutoff (87.5% vs. 20.0%, p <0.001).
CONCLUSION
In the present patients, surgical stress caused an increase in d-ROM during the postoperative course. The d-ROM value obtained during the operation was correlated with long-term survival following resection for lung cancer.
