These types of surgeries remove only the lung mass and a small portion of the lung along with it, whereas other surgeries, like a lobectomy, remove one or more lobes of the lung. Meanwhile, patients with tumors > 3 cm show no difference in survival in regard to the procedure chosen. Lobectomy, segmentectomy, and wedge resection are comparable oncologic procedures for patients with stage IA NSCLC that is 1.0 cm or smaller. There were higher rates of prolonged air leak in the lobectomy group than the wedge resection group (12.5% v. 7%, p = 0.19), but the sample was too small to reach statistical significance. Abstract. However, rates of non–cancer-related deaths were higher in the wedge resection group than in the lobectomy group. • A wedge resection is the removal of a small, wedge-shaped part of lung tissue from a lobe of your lung. For tumors from 1.1 to 2.0 cm, lobectomy and segmentectomy could lead to equivalent survival rates but showed better … I really don't recall what the numbers from my last test were but when going into my 2nd surgery loss of lung function definitely was a concern.

Overall, there was a nonsignificant trend toward better survival times in patients after lobectomy vs wedge resection (mean [± SD] survival time, 5.8 ± 0.3 vs 4.1 ± 0.3 years, respectively; p = 0.112). In this trial, the operative approach (VATS vs thoracotomy), extent of resection (wedge vs segmentectomy) and degree of lymph node evaluation (sampling vs dissection) were left to the discretion of the individual surgeon. Comparison of lobectomy and wedge resection for carcinoma of the lung. The present analysis reports on the variability of surgical technique and nodal staging used among patients enrolled in Z4032. Researchers continue to evaluate optimal surgical approaches for patients with this stage of disease.
Right,B: lobectomy vs wedge resection in tumors < 3 cm.
For tumors from 1.1 to 2.0 cm, lobectomy and segmentectomy could lead to equivalent survival rates but showed better survival rates than that observed with wedge resection.

Overall, there was a nonsignificant trend toward better survival times in patients after lobectomy vs wedge resection (mean [± SD] survival time, 5.8 ± 0.3 vs 4.1 ± 0.3 years, respectively; p = 0.112). (The right lung has three lobes, and the left lung has two lobes. In the matched groups of patients there was no difference in overall or/and 5-year survival observed between the lobectomy and segmentectomy group. During a segmentectomy the surgeon removes a larger piece of lung tissue than in a wedge resection… The extent of parenchymal resection gradually was reduced from pneumonectomy to lobectomy in the early 1960s, and additional attempts to minimize the extent of resection even more, from lobectomy to sublobar resection (i.e., wedge resection and segmentectomy), were made in the 1980s.
A recent retrospective analysis of the results of limited resections compared to formal lobectomy in T1a NSCLC was performed by Dai et al.
These three study groups underwent different type of resection: lobectomy, segmentectomy and wedge resection.
