[Long-term Outcome of Pulmonary Segmentectomy for Lung Cancer].

ABSTRACT

OBJECTIVE: Pulmonary segmentectomy has been performed for patients with radiographic early-stage lung cancer. This retrospective study investigated the validity of choice of procedures at our institute by examining the survival outcomes of lung cancer patients who underwent surgery. METHOD: Data from 354 consecutive patients with pT1a~c N0 M0 stages I A1~3 non-small cell lung cancer who underwent surgery between 2004 and 2014 were extracted (segmentectomy group84 patients, lobectomy group270 patients). Overall, recurrence-free and cancer-specific survival of patients operated by segmentectomy and lobectomy was compared using the Cox proportional hazard model. RESULT: The segmentectomy group had a higher average age and frequency of history of another cancer and smaller lung cancers and its diameter and solid components than the lobectomy group. By univariate and multivariate analyses, surgical procedures were not identified as independent risk factors for overall, recurrence-free and cancer-specific survival. CONCLUSION: In this study cohort, the mode of surgical procedure between segmentectomy and lobectomy did not affect relapse and prognosis in pathological stages I A1~3 lung cancer. The choice of procedures at our institute seemed to be appropriate in this study period.
