Video-assisted thoracoscopic surgery (VATS) is regarded as the standard treatment for lung cancer. However, the feasibility and safety of VATS for lung cancer after neoadjuvant chemoradiotherapy (CRT) is unclear. This study evaluated the feasibility and safety of VATS in patients who had received neoadjuvant CRT.
Methods: Between January 2008 and December 2017, 85 patients who were administered neoadjuvant CRT and underwent anatomic lung resection were enrolled. Fifty-nine patients underwent open thoracotomy and 26 patients underwent VATS. The clinical characteristics and perioperative outcomes were reviewed.
Results: In six of the initial 32 patients who underwent VATS, the procedure was converted to thoracotomy. Adjacent structural invasion (33.9% vs. 11.5%; P = 0.037) and combined resection (16.9% vs. 0%; P = 0.025) were higher in the open group than in the VATS group. Surgical duration was higher in the open group than in the VATS group (203.86 ± 65.97 vs. 173.27 ± 59.87 minutes; P = 0.046). With regard to postoperative outcomes, the length of the hospital stay was longer in the open group compared to the VATS group (14.46 ± 16.94 vs. 8.62 ± 4.72 days; P = 0.017). There was no significant difference in the three-year disease-free survival (69.3% vs. 67.9%; P = 0.879) or overall survival rates (76.6% vs. 61.9%; P = 0.516).
Conclusion: In selected patients, VATS pulmonary resection after neoadjuvant CRT showed results comparable to that of thoracotomy in terms of postoperative outcomes, operative morbidities, and survival rate.
