Abstract

Background

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.

Methods

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.

Results

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.

Conclusions

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