Abstract
Objective: We studied cytokine changes after video-assisted thoracoscopic lobectomy and conventional lobectomy in patients with stage IA lung cancer. Methods: From June, 1997, 20 consecutive patients with stage IA non small-cell lung carcinoma underwent either conventional lobectomy via an open thoracotomy (n = 10) or video-assisted thoracoscopic lobectomy (n = 10). The cytokine concentration in serum and pleural fluid were measured for 6 days postoperatively. Results: Interleukin-6 and interleukin-8 leads peaked at 3 h or 1 day after surgery. Cytokine levels in pleural fluid were more than 100 times higher than corresponding systemic levels. The increase of interleukin-6 in pleural fluid 3 hours after surgery was significantly smaller in video-assisted thoracoscopic lobectomy (3971 ± 2793 pg/mL for video-assisted thoracoscopic lobectomy vs. 23274 ± 8426 pg/mL for open lobectomy). There were no significant differences in the serum interleukin-6 and interleukin-8 concentrations between the 2 groups. Conclusion: The thoracoscopic approach lessened the increase of cytokines in pleural fluid, but benefits of reduced cytokine production in video-assisted thoracoscopy remain to be clarified.
