Background:
This study aims to evaluate the outcomes of sublobar resections in patients with early-stage non-small cell lung cancer and to investigate the factors affecting survival.
Methods:
Medical files of a total of 63 patients (52 males, 11 females; mean age 64 years; range, 39 to 81 years) who underwent sublobar resection for suspected or known early-stage non-small cell lung cancer between January 2001 and August 2013 were retrospectively reviewed. Data including demographic characteristics of the patients, comorbid conditions, smoking status, surgical margin, visceral pleura invasion, distance from surgical margin to tumor, tumor size, pathological N status, cell type, tumor localization, and recurrences were recorded.
Results:
Survival was significantly longer in the patients with negative surgical margin for tumor (R0) than in those with positive margin (R1) (94.1 months vs. 32.2 months, p<0.01). Survival was also significantly longer in the patients without lymphatic invasion (p<0.01).
Conclusion:
In early-stage lung tumors, sublobar resection can be performed, if complete resection is performed. Lymphatic invasion is a negative prognostic factor for survival following sublobar resection.
