Human papillomavirus infection maybe not associated with primary lung cancer in the Fujian population of China.

BACKGROUND

To investigate whether human papillomavirus (HPV) infection is associated with primary lung cancer among the Fujian population.

METHODS

HPV infection was detected in 140 pairs of lung cancer tissues and matched paracancerous tissues by examining the 21 clinically relevant HPV types using a combination of viral highly conserved L1 region PCR amplification and specific probe reverse hybridization. Paired χ test was used to analyze differences in detection rates of HPV between lung cancer and paracancerous tissues. Differences in detection rates of HPV in lung cancer tissues were analyzed using χ test or the exact probability method. The rank sum test was used to analyze differences in the distributions of routine indices of blood and pulmonary function in lung cancer tissues between the HPV negative and positive groups.

RESULTS

HPV infection was detected in 13 of the 140 tumor specimens and in 16 of the paired normal lung tissues. There was no significant correlation between HPV infection and lung cancer (P > 0.05). The diagnosed HPV infection rates did not differ significantly among lung cancer tissues with different stratification (P > 0.05). However, the platelet count, platelet pressure, residual gas volume, functional residual volume, and residual gas volume/lung total distribution may differ between HPV-negative and HPV-positive lung cancer tissues (0.000625 < P < 0.05).

CONCLUSIONS

We concluded that HPV infection may not be associated with the risk of primary lung cancer in the Fujian population. However, HPV infection may affect platelet and residual lung function in primary lung cancer patients.
