To leam whether HPV16 E6/E7 genes correlate with cervical carcinoma and precancerous lesions. Methods Amplification and cloning of HPV16 E6/E7 genes were performed by PCR and molecular biological techniques for their sequences. Cervical cancer, CIN Ⅱ - Ⅲ and cervicitis were confirmed by pathologic detections. Results Detection rates of HPV16 E6/E7 in biopsies of cervical carcinoma, CIN Ⅱ - Ⅲ and cervicitis were individually 70%, 75% and 65%. Statistic results show that there is no difference among them in HPV16 E7 detection. Also ther is no difference between cervical cancer and CIN Ⅱ - Ⅲ in HPV16 E6 detection, however, both were higher detections than in cervicitis statistically. Conclusion HPV16 E6/E7 genes correlate with cervical carcinoma and precancerous lesions. E6 gene might especially function on occurrence of cervical carcinoma from precancerous lesions.
