Patients and Methods
The study group consisted of 83 patients: 45 of them underwent lobectomy and the other 38 underwent segmentectomy. This study was conducted with the approval of the institutional ethics board and informed consent was obtained from all patients. No specific preoperative and postoperative rehabilitation programs were established.
The eligibility criteria for segmentectomy in this study were as follows: patients who had a cT1N0M0 non–small-cell lung cancer 2 cm or smaller in all dimensions on
Results
The clinical preoperative characteristics and average number of resected segments in the lobectomy and the segmentectomy groups are shown in Table 1. There were no significant differences in preoperative functional factors between the two groups, confirming that the patients with segmentectomy included in this study could tolerate a lobectomy. The number of segments actually removed was halved in the case of segmentectomy (1.9 ± 0.9 versus 3.9 ± 1.1). The cell type of the tumor was
Comment
One of the controversies regarding lesser resection is whether the procedure itself can provide postsurgical functional benefit or not. There have been two reports suggesting that limited resection, including segmentectomy, could provide little functional advantage over lobectomy [1, 13]. In 1995, the Lung Cancer Study Group showed no significant differences in FVC between patients undergoing lobectomy and those undergoing limited resection [1]. Despite the fact that their data demonstrated a
