ABSTRACT
<p><b>OBJECTIVE</b>To investigate human papillomavirus (HPV) infection and genotyping in patients with cervical cancer in Guangzhou in the last 3 decades.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
