Outline of Final Research Achievements

We consider that progressive steps of lung adenocarcinoma may start from proliferation of bronchiolar epitheli, to atypical adenomatous hyperplasia (AAH), adenocarcinoma in situ (AIS), to minimally invasive adenocarcinoma, finally to lepidic pattern adenocarcinoma, and examined and compared the clinic-pathological features of resected operation materials of lung adenocarcinoma with lung fibrosis/interstitial pneumonia and without lung fibrosis/interstitial pneumonia. Of over all the materials of lung adenocarcinoma, lung fibrosis/interstitial pneumonia was found in 20.6%, AAH in 23.6%, multiple cancers in 13.2%, and bronchiolization of alveoli in 23.5%. AAH and bronchiolization of alveoli were significantly more observed in lung adenocarcinoma with lung fibrosis/interstitial pneumonia. This finding suggest lung fibrosis and bronchiolization of alveoli may have an important role.
