Objective:
Pneumonectomy may be needed in exceptional cases in patients with early stage NSCLC, especially in stage IB. The aim of this study was to evaluate whether overall survival in stage IB (T2aN0M0) NSCLC patients is worse after pneumonectomy.
Methods:
Retrospective study of a series of pathological IB (pIB) patients who underwent either lobectomy or pneumonectomy between 2000 and 2011. The dependent variable was all-cause death. Operative mortality was excluded. The relationship between the age, FEV1%, Charlson index and performance of pneumonectomy variables and the dependent variable were analyzed using a Cox regression. Overall survival for both groups of patients was then plotted in Kaplan-Meier graphs and compared using the log-rank test.
Results:
A total of 407 cases were analyzed (373 lobectomies and 34 pneumonectomies). According to Cox regression, age, FEV1% and pneumonectomy were associated with poorer survival (P<.05). Age-adjusted survival and FEV1% showed diminished survival in patients who underwent pneumonectomy (log-rank, P=.0357).
Conclusions:
In stage pIB NSCLC patients, pneumonectomy is associated with poorer survival compared to lobectomy.
