Comparison of Thoracoscopic Segmentectomy and Thoracoscopic Lobectomy for Small-Sized Stage IA Lung Cancer
Annals of Thoracic Surgery, 07/27/2012
Zhong C et al. – Thoracoscopic segmentectomy is a safe option and provides comparable oncologic results to thoracoscopic lobectomy for small (≤2 cm) peripheral stage IA non–small cell lung cancer. Tumor size is an independent prognostic factor of disease–free survival for stage IA patients with small–sized lesions.Methods
- Between March 2006 and August 2011, 39 thoracoscopic segmentectomies and 81 thoracoscopic lobectomies were performed in 120 patients with small–sized (≤2 cm) stage IA lung cancer.
- Clinicopathologic factors, local recurrence rate, and survival rate were compared.
- The two groups were similar in age, sex, pulmonary function, and tumor size.
- There were no conversions from video–assisted thoracoscopic surgery to open or from segmentectomy to lobectomy.
- There were no in–hospital deaths.
- The two groups had a similar incidence of postoperative complications.
- Local recurrence rates were similar after thoracoscopic segmentectomy (5.1%) and thoracoscopic lobectomy (4.9%).
- No significant difference was observed in 5–year overall or disease–free survivals after thoracoscopic segmentectomy or thoracoscopic lobectomy.
- Multivariate Cox regression analyses showed tumor size was the only independent prognostic factor for disease–free survival.
