title: [Study on the relationship between genesis and development of cervical cancer and the infection of human papillomavirus type 16/18, human herpesvirus II and cytomegalovirus].
abstract: OBJECTIVE
  To investigate the correlation between genesis and the development of cervical cancer and infection of human papillomavirus (HPV) type 16/18, human herpesvirus II (HSV- II) and cytomegalovirus(CMV).
  
  
  METHODS
  Different viruses were determined by polymerase chain reaction in 156 specimens of uterine including cervix 43 cervical cancer specimens,47 cervical intraepithelial neoplasia (CIN) specimens, 56 cervicitis specimens and 10 normal cervix specimens.
  
  
  RESULTS
  (1) Positive rates on different viruses: the positive rates of HSV- II, HPV16/18 and CMV were declining in the cervical cancer specimens, CIN specimens or CIN III specimens and CIN I - II specimens, with significant differences. (2)Positive rate and grading, staging and histogenesis of cervical cancer on different viruses as well as positive rates of HPV16/18 in II staging cervical cancer specimens were significantly higher than that in I staging cervical cancer specimens while positive rates of HPV16/18 and HSV- II in high differentiation of cervical cancer specimens were significantly higher than those with medium differentiation from cervical cancer specimens. Positive rates of CMV did not seem to correlate with positive rate of HSV- II and CMV was not correlated to grading, staging or histogenesis of cervical cancer. (3)Copies of infected virus, HSV-II and HPV16/18 showing cervical cancer>CIN> cervicitis while with CMV:cervical cancer>CIN. (4) There were mixed infections of different viruses as HPV16/18 + HSV- II > HPV16/18 + CMV seen in the study.
  
  
  CONCLUSIONS
  HPV 16/18, HSV- II and CMV infection were closely related to the genesis of cervical cancer and quantity of viruses which might have played an important role in carcinogenesis of cervical lesions.
