Abstract

Objective: Recurrence after surgical resection is the most common cause of treatment failure in patients with non-small-cell lung cancer. The aim of the study is to investigate the prognostic factors of postrecurrence survival (PRS) in patients of resected lung adenocarcinoma. Methods: The clinicopathological characteristics of 179 patients with recurrence after complete resection of lung adenocarcinoma at Taipei Veterans General Hospital between 2004 and 2010 were retrospectively reviewed. The prognostic and predictive effects of these clinicopathological variables in PRS were analyzed. Results: The pattern of recurrence included local only in 25 (15.4%), distant only in 56 (34.6%), and both local and distant in 81 (50.0%) of patients. The 2-year and 5-year PRS were 65.2% and 29.8%, respectively. The most common organ sites of metastasis were the contralateral lung (39.1%), followed by the brain (33.5%) and the bone (31.3%). Multivariate analysis revealed that micropapillary/solid predominant pattern group (versus acinar/papillary; hazard ratio = 2.615; 95% confidence interval: 1.395-4.901; p = 0.003) and no treatment for recurrence (p < 0.001) were significant prognostic factors of worse PRS. For patients receiving treatment for recurrence, micropapillary/solid predominant pattern group (versus acinar/papillary; hazard ratio = 2.570; 95% confidence interval: 1.357-4.865; p = 0.004) was a significant predictive factor of worse PRS. Treatment for recurrence with surgery (p = 0.067) tended to be a significant predictive factor of better PRS. Conclusions: In lung adenocarcinoma, micropapillary/solid predominant pattern group (versus acinar/papillary) was a significant poor prognostic factor for PRS.
