Clinicopathological implications of EpCAM expression in adenocarcinoma of the lung.

Abstract:

BACKGROUND:The frequency of epithelial cell adhesion molecule (EpCAM) expression was investigated in non-small cell lung cancer (NSCLC) cells and human tissues, and its clinicopathological significance in adenocarcinoma of the lung was evaluated. MATERIALS AND METHODS:EpCAM expression was analysed by reverse transcription-polymerase chain reaction (RT-PCR) and flow cytometry in human NSCLC cells. EpCAM protein expression was evaluated in 234 adenocarcinoma tissues using immunohistochemistry. RESULTS:A high expression level of EpCAM was observed in human NSCLC cells by flow cytometry and RT-PCR. EpCAM overexpression was detected in 120/234 (51.3%) surgically resected adenocarcinoma tissues. EpCAM overexpression occurred significantly more frequently in adenocarcinoma than in bronchioloalveolar carcinoma (p=0.02). The overall survival did not differ significantly between EpCAM-overexpressing and EpCAM-negative patients (p=0.40). CONCLUSION:These findings suggest EpCAM plays a role in the carcinogenesis of adenocarcinoma of the lung and might provide a promising molecule for targeted therapy in NSCLC.

  • Role of Hyaluronan and Glucose on 4-Methylumbelliferone-inhibited Cell Proliferation in Breast Carcinoma Cells.

    abstract:BACKGROUND/AIM:4-methylumbelliferone (4-MU) has received considerable attention due to its potential for cancer treatment since it inhibits cell proliferation, migration and invasion. An increasing body of evidence suggests that extracellular matrix (e.g. hyaluronan) and nutrients (e.g. glucose) in the tumor microenvir...
