“…We also showed the feasibility of HPV genotyping from paraffin embedded blocks in a tropical region. All previous work on HPV epidemiology in Guadeloupe were performed on fresh samples [14,19,20]. Archiving paraffin embedded blocks in tropical regions with humid weather, is known to hamper DNA extraction and amplification during HPV genotyping [21].…”

Background Cervical cancer is the fourth cancer worldwide. The Human Papilloma Virus is responsible for 99% of the cases but the distribution of its genotypes varies among populations. We aimed to identify HPV genotypes distribution in women with grade 2/3 cervical intraepithelial dysplasia or invasive cervical cancer in Guadeloupe, a French Caribbean territory with a population mainly of African descent. Methods We used paraffin-embedded tumors for viral DNA extraction from women diagnosed between 2014 and 2016 and identified by the population-based cancer registry. The HPV Genotyping was performed with the InnoLIPA HPV Genotyping Extra kit®. Results Overall, 213 samples out of the 321 eligible records were analyzed. The HPV status was positive for 94% of the cases. The five most common oncogenic HPV genotypes were HPV31 (47%), HPV33 (38%), HPV16 (32%), HPV44 (31%) and HPV26 (28%). HPV18 was found in only in 5% of the cases. Among the studied cases, 94% had multiple infections. More than 60% of single infections were HPV16-related, accounting for 35% of HPV16 infections. Conclusions These results show a different distribution of oncogenic HPVs in Guadeloupe with “31 > 33 > 16” and a high frequency of multiple infections. Despite a lower coverage, the nine-valent vaccine is nevertheless adequate.
