    Background:
    Segmentectomy is thought to be able to spare lung parenchyma compared with lobectomy. On the other hand it might cause more local recurrences. The management of local recurrence after segmentectomy is thought to be an important issue. The aim of this study is to evaluate the management of local recurrence after segmentectomy.
    
    Method:
    From June 2005 to March 2009 we performed segmentectomy for clinical stage IA lung cancer, 88 male and 91 female with mean age of 66 year-old (32-83). The histological types of 179 lung tumors according to WHO histological classification are as follows: atypical adenomatous hyperplasia (2), adenocarcinoma in situ (34), minimally invasive adenocarcinoma (27), invasive adenocarcinoma (96), Squamous cell carcinoma (2), adenosquamous carcinoma (4), and carcinoid (2), respectively. Median follow-up time was 2920 days. During follow up there were 15 recurrences. Of 15 cases with recurrence 6 cases had local recurrences without distant metastasis.
    
    Result:
    Figure 1Mean time to local recurrence after segmentectomy was 1595 ± 1027 days (356－2965). Of 6 cases with local recurrence 5 cases had micropapillary component more than 5 %. The initial treatments for local recurrence were as follows: completion lobectomy (4), radiation (1), radiofrequency ablation (1), respectively. Three of 6 cases have been alive without evidence of disease since initial treatment for local recurrence of lung cancer.
    
    
    
    Conclusion:
    Management of local recurrence after segmentectomy is important. Local treatment, such as, completion lobectomy, radiation, or radio frequency ablation may effective for selected cases.
