title: [Identification and genotyping of oncogenic type of human papillomavirus in paraffin-embedded cervical cancer samples in Guangzhou].
abstract: OBJECTIVE
  To investigate human papillomavirus (HPV) infection and genotyping in patients with cervical cancer in Guangzhou in the last 3 decades.
  
  
  METHODS
  HPV L1 gene fragment in paraffin-embedded cervical cancer samples was amplified by HPV-specific PCR with consensus primers, and typing of HPV strains was performed on the basis of sequence analysis of the PCR products.
  
  
  RESULTS
  The positivity rates of HPV DNA was 26.2% in the 99 cases of cervical cancer. Five HPV genotypes were identified including HPV16, 18, 33, 52 and 58.
  
  
  CONCLUSIONS
  HPV16, 58 and 33 are the most common genotypes of HPV, accounting for over 88.4% in the total infected cases, suggesting that the HPV genotypes closely related to cervical cancer is more centralized in Guangzhou.
