Abstract: Human papilloma virus (HPV) infection remains a worldwide concern, especially in Sub-Saharan Africa where cervical cancer is the leading cause of cancer death in women. The aim of the study was to determine the prevalence and genotypic distribution of High-Risk HPV (HR-HPV) involved in Cervical Intraepithelial Neoplasia (CIN) II and III and in cervical cancer in Parakou. Out of a total of 149 samples of cervical tissues archived, fixed and paraffin-embedded, 78 samples with histological diagnosis of CIN-II, CIN-III and cervical cancer went through deparaffinization with xylene, followed by an extraction of HPV DNA and the detection of HR-HPV by real-time multiplex PCR. The average age of the women was 40.05±13.99 years. The samples were positive to at least one HR-HPV genotype in 76.92% (50/65) of cases. The HR-HPV genotypes which are most common in the cervical cancer and in CIN-II and III were, respectively HPV-39 (38 and 37.50%), HPV-18 (35 and 31.30%), HPV-45 (35 and 31.30%), HPV-35 (9 and 25%) and HPV-52 (9 and 12.50%). The HPV-16 was absent. This study helped to detect (in samples archived, fixed and paraffin-embedded tissues) HR-HPV involved in high-grade precancerous lesions and in cervical cancer in Parakou, some of which are not covered by currently available vaccines.
