Abstract
Objective
Segmentectomy is widely performed for early-stage lung cancer. However, the
effects of segmentectomy versus lobectomy on pulmonary function remain
unclear. We performed a meta-analysis with the aim of comparing
segmentectomy and lobectomy in terms of preservation of pulmonary function
in patients with early-stage non-small-cell lung cancer (NSCLC).
Methods
We conducted a literature search of PubMed using the terms ‘pulmonary
function’ AND ‘segmentectomy’ AND ‘lobectomy’. The primary outcomes of
interest were the forced expiratory volume in 1 second (FEV1), FEV1 as
percent of predicted (%FEV1), change in FEV1 (Δ%FEV1), and the ratio of
postoperative to preoperative FEV1.
Results
Thirteen studies comprising 2027 patients met the inclusion and exclusion
criteria and were included for analysis, including 787 patients in the
segmentectomy group and 1240 patients in the lobectomy group. Patients in
the segmentectomy group showed significantly better preservation of FEV1 and
%FEV1 compared with the lobectomy group. The reduction in FEV1 after surgery
was significantly less in the segmentectomy group compared with the
lobectomy group, and Δ%FEV1 was significantly higher in the segmentectomy
group than in the lobectomy group.
Conclusion
Segmentectomy results in better preservation of pulmonary function compared
with lobectomy in patients with early-stage NSCLC.
