Abstract

Objective: To analyze the clinical features and prognostic factors of different histological subtypes of lung adenocarcinoma. Methods: Data from 370 lung adenocarcinoma patients who underwent surgical resection for pathologically supported adenocarcinoma in our hospital between 2000 and 2003 were retrospectively reviewed. The Kaplan-Meier method was used to estimate patient survival, and Cox's proportional hazards model was performed for multivariate analysis. Results: The 5-year overall survival rate was 25.26%, and the mean survival time was 3.89 years. In multivariate analysis, histological subtype, incised margin residual, TNM stage, tumor size, and adjuvant chemotherapy were identified as independent survival predictors. The 5-year survival rate in bronchioloalveolar adenocarcinoma (BAC) patients was 41.30%, higher than in patients with other subtypes of lung adenocarcinoma (P=0.002). No significant difference was found in the prognosis among patients with different subtypes of adenocarcinoma without a BAC component. Conclusion: Adenocarcinoma with a BAC component is an independent subtype of lung adenocarcinoma. Its prognosis lies between those of BAC and adenocarcinoma without BAC. Histological subtype, incised margin residual, TNM stage, tumor size, and adjuvant chemotherapy are independent survival predictors.
