| Outline of Final Research Achievements |
The factors conferrng the increased malignancy on lung adenocarcinoma with micropapillary component (AC-MPC) remain to be elucidated. 2-dimensional gel electrophoresis, several proteins differentially expressed between AC-MPC and conventional adenocarcinoma (CAC); in particular, vimentin, one of the proteins, was most up-regulated in AC-MPC. Immunohistochemistry revealed that vimentin was expressed in most of MPC. Within the AC-MPC entity, higher vimentin expression was correlated with more frequent vascular invasion and more advanced node metastasis (P<0.05), and multivariate analysis showed that high vimentin expression and worse node statuses were independent indicators of adverse prognosis (P<0.05). In conclusion, vimentin expression is prevalent and markedly up-regulated in MPC, which might reflect the biological essence of poorer differentiation or dedifferentiation of MPC, and this might have a role in the increase of invasiveness and consequent more malignant nature of MPC.
