Single and multiple high-risk and low-risk Human Papillomavirus association with cervical lesions of 11,224 women in Jakarta.

PURPOSE

We sought to evaluate prevalence, age-adjusted distribution, and impact of single and multiple high- and low-risk human papillomavirus (HPV) subtypes and their associations with cervical lesions.

METHODS

Data were extracted from 11,224 women who underwent routine screening of HPV genotyping and liquid-based cytology co-testing. Fifteen high-risk (HR) and six low-risk (LR) HPV types were genotyped.

RESULTS

Overall HPV prevalence was 10.7 %, and young women (under 21 years old) harbored highest HPV infection rate (40.38 %). The rate declined in old women 9.49 % (age 30-49) and 6.89 % (age 50 and above). Normal cytology had lowest HPV (5.66 %) compared to low-grade (60.49 %), high-grade (71.96 %) squamous intraepithelial lesions (LSIL and HSIL) and squamous cell carcinoma SCC (86.9 %). LR HPV subtypes were absent in SCC and were consistently lower than HR HPV in LSIL (6.74 vs. 33.54 %) and HSIL (2.12 vs. 51.32 %). Multiple HPV infection was more frequent in young women under 30 years old (10 %) than older women (2 %) and in LSIL (20.2 %), HSIL (18.5 %) than SCC (4.4 %). HR HPV 52, 16, 18, and 58 were the most frequent subtypes in normal, LSIL, and HSIL. Greater or equal proportion of HPV 16, 18, 45, and 52 was found in SCC compared to normal cytology (SCC/normal ratios 4.8, 1.2, 1.6, and 1.7). While important in LSIL and HSIL, HPV58 was not detected in SCC.

CONCLUSION

Taken together, identification of these HPV types, especially HPV 16, 18, 45, and 52, and their associated cervical lesions may improve cervical cancer preventive strategies in Indonesia.
