목적 : There are various factors related to the prognosis of completely resected non-small cell lung cancer. However, there is only few numbers of researches about the impact of incomplete interlobar fissure on survival or recurrence rate. This study is to figure out survival and recurrence rate of stage IA and IIA (N0) lung cancer patients with incomplete interlobar fissure after thoracoscopic lobectomy.

방법 : Retrospective analysis was initiated to 123 patients diagnosed as stage IA to IIA(N0) after video-assisted thoracoscopic surgery (VATS) lobectomy for treatment of non-small cell lung cancer from Jan. 2006 to Aug. 2014. To find out the impact of T stage on early stage lung cancer specifically, N stage and T3 were excluded. Patients were divided in groups of complete interlobar fissure group (C, 70 patients) and incomplete interlobar fissure group (IC, 53 patients). Incomplete interlobar fissures were divided with endoscopic staplers during VATS lobectomy in patients with early stage non-small cell lung cancer

결과 : 5-year overall survival rate was not statistically significant in each group (82.8% in group C vs. 90.4% in group IC). 5-year overall survival rates in each group were statistically insignificant according to the T stage: T1a - 96.2% in 25 and 93.8% in 12 patients, T1b - 100% in 21 and 93.8% in 18 patients, T2a - 75% in 19 and 83.5% in 22 patients, T2b - 75% in 4 and 100% in 1 patients (p=0.178). 5-year recurrence-free survival rate was 84.9% and 79.2% for each group (p=0.552). According to T stage, 5-year recurrence-free survival rate were also statistically insignificant: T1a - 86.4% and 90%, T1b - 92.9% and 87.5%, T2a - 69.6% and 71.3%, T2b - 100% and 0% (p=0.893). According to tumor histology, there was no significant difference about 5-year overall survival and recurrence-free survival rate in each group. There were 2 patients who had recurrences on the ipsilateral lung, and 7 patients with distant metastases in group C. IC group had 4 patients who had recurrences on the ipsilateral lung, and 4 patients with distant metastases.

결론 : Incomplete interlobar fissure of the lung did not affect prognosis of patients who had underwent VATS lobectomy for early stage non-small lung cancer.
