Objective： To investigate the expressions and the clinical significance of P53, C-erbB-2 and vascular endothelial growth factor （VEGF） in non-small cell lung cancer （NSCLC）. Methods： 121 specimens of NSCLC were examined for P53, C-erbB-2 and VEGF by immunohistochemical staining. Results： The positive rates of P53, C-erbB-2 and VEGF in the carcinomatous tissue were 43%, 39% and 31% respectively. P53 gene protein expression in lung cancer was significantly related to histological type and P-TNM staging of lung cancer patients （P 〈 0.05）, and was not associated with the sex, age, the size of primary cancer, lymph node metastasis and cell differentiation （P 〉 0.05）. C-erbB-2 gene protein expression in lung cancer was closely related to histological type and cell differentiation （P 〈 0.05）, and was not associated with the sex, age, the size of primary cancer, lymph node metastasis and P-TNM staging of lung cancer patients （P 〉 0.05）. VEGF in lung cancer was only closely related to cell differentiation （P 〈 0.05）, and was not associated with the sex, age, the size of pdmary cancer, lymph node metastasis, histological type and P-TNM staging of lung cancer patients （P 〉 0.05）. Conclusion： It is possible for P53, C-erbB-2 and VEGF to play an important role in the oncogenesis and development of non-small cell lung cancer.
