Objective Human Papillomavirus (HPV) is necessary to the development of cervical cancer.Until now,the distribution of specific HPV type has not been identified clearly yet.Besides,the relationship between age and the HPV type-specific distribution in cervical adenocarcinoma needs to be further investigated.Methods This study included 32 specimens of cervical adenocarcinoma out of a multicenter clinical study in China.The specimen blocks were sliced by sandwich method.DNA was amplified by SPF10-PCR method.DNA genotyping used LiPA method.All biopsy specimens had pathologic diagnosis.The prevalence of HPV type-specific distribution was described and the differences were analyzed statistically.Results 32 adenocarcinoma cases were included in this sttudy.HPV positive rate was 53.1％ (17/32).HPV-18 was the most prevalent type,which took up 47.4 ％ (8/17) of the total HPV positive cases,followed by HPV-16,which took up 26.3 ％ (5/17) of the total HPV positive cases.Other HPV types detected were HPV-39,HPV-45 and HPV-66.One multi-infection case was found (HPV-18 and HPV-66 co-infection).The average ages of HPV-16 and HPV-18 were 48.6 and 40.6 years old respectively,which showed statistically difference (P =0.049).When the patients younger than 50 years old were compared with the patients equal or older than 50 years old as two age groups,HPV positive rate did not show significantly statistical difference (P =0.074) between the two age groups.The prevalence of HPV-18 manifested significant differences between the two age groups in both HPV positive adenocarcinoma cases and overall adenocarcinoma cases (P =0.029and P =0.003 respectively).The prevalence of HPV-16 did not show any significant statistical difference between the two age groups in either HPV positive adenocarcinoma cases or overall adenocarcinoma cases (P =0.6 and P =1 respectively).HPV-16 and/or HPV-18 infection (at least one positive) in HPV positive adenocarcinoma cases did not have statistical significance (P =0.052),while in overall adenocarcinoma cases,HPV-16 and/or HPV-18 infection presented significant statistical difference (P =0.005).Conclusion HPV-18 and HPV-16 were two most prevalent HPV types in cervical adenocarcinoma.HPV infection and HPV-18infection were more common in young women.The prevalence of HPV-16 was more common in older adenocarcinoma cases compared with HPV-18.Those findings will provide evidence for the evaluation of HPV vaccine in preventing cervix related diseases.
