Outline of Final Research Achievements |
Surgically resected lung adenocarcinomas with and without lymph node metastasis and biopsy samples from inoperably advanced tumors were examined pathologically. The micropapillary element was clarified to be an exclusive determinant of malignant potential in EGFR-mutated lung adenocarcinomas. Pathological features and mucin family protein expression profile of idiopathic interstitial pneumonia (IIP)-associated pulmonary adenocarcinomas was investigated. In the IIP group, expression of MUC1, MUC7 and MUC21 was lower, and that of MUC4, MUC5AC, MUC5 and MUC9 was higher than non-IIP group. In the TRU group cases, IIP group cases showed distinctly lower expression of MUC1, and higher expression of MUC4, MUC5B and MUC9 than non-IIP group cases. Expression of MUC21 was tightly linked to micropapillary and low papillary lepidic variants.IIP-associated pulmonary adenocarcinomas, especially those of TRU group, showed specific expression profile of mucin family proteins.
