Abstract:
Objective The international multidisciplinary lung adenocarcinoma classification was published by IASLC/ ATS/ERS in 2011.This study aimed to explore the clinicopathologic characteristics of lung adenocarcinoma based on IASLC/ATS/ERS classification and validate its clinical diagnostic and therapeutic value.Methods 2 056 cases of surgical resection from Shanghai Chest Hospital were classified according to the new classification and clinical information were retrospectively reviewed.The clinicopathologic characteristics based on new classification were analyzed statistically.Results Our data indicated that women were in high risk of lung adenocarcinoma; The average age of onset was 59-year-old; the female patients were younger than the male patients (58.7 years vs 60.2 years,P ＜ 0.01) ; Average tumor diameter was 2.6 centimeter; right lung was more popular than left and superior lobe than the inferior one.Acinar predominant subtype and papillary predominant subtype were frequently observed.Micropapillary predominant subtype and solid predominant subtype were identified to be more aggressive than other histopathologic subtypes.Most patients were classified as stage Ⅰ(71.7％),which were predominantly stage Ⅰa (53.1％).Conclusion The new classification is superior to reflect the clinicopathologic characteristics of lung adenocarcinoma and satisfy clinical needs,especially contributing to change and update the surgical strategy of early stage lung adenocarcinoma.
