Abstract

Biological behavior of lung cancer was evaluated by basic study. Malignancy Associated Change is the concept that the nuclear features of normal cells in the vicinity of cancer show subtle morphological difference from those of healthy individuals. The difference was recognized by high resolution cytometry and the expression of MAC cells was correlated with the degree of abnormality of chest diseases. Comparative genomic hybridization and fluorescence in situ hybridization were performed to investigate genetic abnormality of. Multiple genetic abnormalities and chromosomal instability showed poor prognosis. Two dimensional electrophoresis was employed to detect the expression of the specific protein of lung cancer. TAO2 was proved to be specific to well differentiated adenocarcinoma. Also, metabolic analysis will be employed for cell analysis.
