Objective: We compared the clinical outcomes and changes in pulmonary function test (PFT) results after segmentectomy or lobectomy for non-small cell lung cancer.

Methods: The retrospective study included 212 patients who had undergone segmentectomy (group S) and 2336 patients who had undergone lobectomy (group L) from 1997 to 2012. The follow-up and medical record data were collected. We used all the longitudinal PFT data within 24 months postoperatively and performed linear mixed modeling. We analyzed the 5-year overall and disease-free survival in stage IA patients. We used propensity score case matching to minimize the bias due to imbalanced group comparisons.

Results: During the perioperative period, 1 death (0.4%) in group S and 7 (0.3%) in group L occurred. The hospital stay for the 2 groups was similar (median, 5.0 vs 5.0 days; range, 2-99 vs 2-58). The mean overall and disease-free survival period of those with T1a after segmentectomy or lobectomy seemed to be similar (4.2 vs 4.5 years, P = .06; and 4.1 vs 4.4 years, P = .07, respectively). Compared with segmentectomy, lobectomy yielded marginally significantly better overall (4.4 vs 3.9 years, P = .05) and disease-free (4.1 vs 3.6 years; P = .05) survival in those with T1b. We did not find a significantly different effect on the PFTs after segmentectomy or lobectomy.

Conclusions: Both surgical types were safe. We would advocate lobectomy for patients with stage IA disease, especially those with T1b. A retrospective study with a large sample size and more detailed information should be conducted for PFT evaluation, with additional stratification by lobe and laterality.
