| Research Abstract |
Human Papilloma Virus (HPV) infection on anal epithelium is a risk for anal cancer. Anal cancer in men who have sex with men (MSM) would be substantial concern in developing countries where management of HIV infection has been improved significantly. We conducted anal cell cytology and HPV typing in MSM in Thailand; and found that atypical squamous cells were seen very frequently in this population. As expected, most MSM were infected with HPV on their anal cells. MSM with HIV infection carried HPV at significantly higher rate. Intriguingly, most MSM were infected with more than 3 different HPV subtypes, and many of them were subtype not covered by currently available HPV vaccine. This study will inform for future development of HPV vaccine for prevention of anal cell cancer in this geographical area.
