To investigate if HPV16, 18 infection, P53 expression and telomerase activity have the differences among different ethnic patient groups with lung cancer, and their significance.


HPV16, 18-DNA, P53 protein overexpression in 110 specimens of lung cancer were detected by PCR and immunohistochemistry, respectively. And telomerase activity in 22 specimens of fresh lung cancer tissues was detected by PCR-TRAP.


The positive rate of HPV16, 18-DNA in the lung cancer group was higher than the normal tissues group and inflammatory lesions group (all P < 0.01). The positive rate of P53 protein overexpression was 57% in the lung cancer group, negative in the normal tissues group (P < 0.01). The differences of HPV16, 18 infection and P53 overexpression have no statistic significance among different ethnic groups (all P > 0.05). The telomerase activity was higher in the cancer tissues (86%) compared with the adjacent normal tissues (22%, P < 0.01).


HPV16, 18 infection might have etiologic significance for lung cancer and make p53 gene overexpression to cause carcinogenesis, but each might have its own carcinogenic process. The high telomerase activity could be a marker of biomolecular change in lung cancer. The different ethnic background of HPV16, 18 infection and P53 overexpression of lung cancer need to do further study with a large number of specimens in the future.
