Objectives:
This study aimed to compare the real-world outcomes of segmentectomy and lobectomy for lung cancer after adjusting for background factors and the extent of lymphadenectomy.
Methods:
This retrospective cohort study used a nationwide database in Japan. The data of patients with clinical stage 0/IA lung cancer who underwent segmentectomy or lobectomy between 2017 and 2019 were retrieved. Short-term postoperative outcomes were compared between the segmentectomy and lobectomy groups using propensity score-matched analysis.
Results:
In the total cohort of 59 663 patients, 11 975 and 47 688 patients were in the segmentectomy and lobectomy groups, respectively. After propensity score matching, 8426 matched patients from each group were retrieved. All confounders including age, sex, comorbidities, smoking history, respiratory function, tumour size, clinical stage, affected lobe and extent of lymphadenectomy were appropriately adjusted. The overall complication rate and the cardiopulmonary complication rate were lower in the segmentectomy group than in the lobectomy group (8.5% vs 11.2%, P < 0.001 and 7.5% vs 10.3%, P < 0.001, respectively). The incidence of prolonged air leak was also lower after segmentectomy than after lobectomy (3.6% vs 5.3%). Surgical mortality, operative time and blood loss volume were comparable between the 2 groups.
Conclusions:
The postoperative complication rate was lower with segmentectomy than with lobectomy for early-stage lung cancer.
