BACKGROUND: Anatomic lobectomy with mediastinal lymph node dissection is considered the optimal management for early stage @entity1149 ( @entity1149 ). Limited lung resection may be preferable in the elderly population, who are more likely to have poor pulmonary reserve and multiple comorbidities. Our primary objective was to compare the survival of @entity1 aged >= 75  y who underwent sublobar resection or lobectomy for stage IA @entity1149 . MATERIALS AND METHODS: We queried the Surveillance, Epidemiology, and End Results database for @entity1 aged >= 75  y who were diagnosed with stage IA @entity1149 from 1998-2007. @entity1 were divided into three groups based on the type of surgery performed (wedge resection, segmentectomy, and lobectomy). Kaplan-Meier analysis and Cox proportional hazard model were used for survival analysis. RESULTS: A total of 1640 @entity1 were analyzed. Lobectomy was performed in 1051 @entity1 , 119 underwent segmentectomy, and 470 @entity1 had wedge resection. Overall and @entity5 -specific survival were significantly lower in the wedge resection group as compared with those in lobectomy (P  <  0.05). However, for @entity13712 @entity5 , no significant difference was found in risk adjusted 5-y @entity5 -specific survival for @entity1 who underwent wedge resection, segmentectomy (hazard ratio, 1.009; 95% confidence interval 0.624-1.631; P  =  0.972), or lobectomy (hazard ratio, 0.98; 95% confidence interval, 0.691-1.388; P  =  0.908). CONCLUSIONS: Sublobar resection is not inferior to lobectomy for @entity13712 N0 M0 @entity1149 in the elderly and should be considered a viable alternative in this high-risk population.

Sublobar resection is equivalent to lobectomy for  XXXX @entity1149 in the elderly: a  Surveillance, Epidemiology, and End Results database analysis.
