Background: Segmentectomy for small or early stage non-small cell lung cancer (NSCLC) has been controversial. Further, video-assisted thoracic surgery (VATS) for lung cancer was accepted during the past decade. We here compared the outcome between VATS segmentectomy and VATS lobectomy for stage I NSCLC.
Methods: In the retrospective study, 109 consecutive patients in stage I underwent surgery at Oita University Hospital (Oita, Japan) between September 2003 and October 2008. VATS segmentectomy was performed in 38 patients and VATS lobectomy with systemic lymphadenectomy was performed in 71 patients. After clinicopathologic factors were compared in both groups, local recurrence rates and survivals were compared.
Results: Five of 38 VATS segmentectomy and eight of 71 VATS lobectomy patients relapsed during the follow-up period (median 27.5 mo). In the relapsed patients after VATS segmentectomy, three (7.9%) were local recurrences and two (5.3%) were distant metastases. On the other hand, four (5.6%) were local recurrence and four (5.6%) were distant metastases in the VATS lobectomy group. There was no significant difference between the two groups. Furthermore, there was no difference in recurrence-free and overall survival between segmentectomy and lobectomy.
Conclusions: Although the sample size is small, VATS segmentectomy is one of the appropriate procedures for stage I NSCLC.
