Prevalence and distribution of high-risk human papillomavirus genotypes in cervical carcinoma, low-grade, and high-grade squamous intraepithelial lesions in Jordanian women

PURPOSE

To assess high-risk human papillomavirus (HR-HPV) prevalence, and genotype distribution in invasive cervical cancer (CC) and its precursors in Jordanian patients.

MATERIALS AND METHODS

A total of 124 different specimens of formalin-fixed, paraffin embedded samples, including 18 low-grade squamous intraepithelial lesions (LSILs), 28 high grade squamous intraepithelial lesions (HSILs), and 78 CCs were included in this study. HPV detection and typing was done using HPV High Risk Typing Real-TM Kit that enables the concomitant detection of the 12 most common HR-HPVs.

RESULTS

Overall, HR-HPV prevalence was 87.2%, 78.6%, and 72.2% in CC, HSIL, and LSIL respectively. Genotype 16 was the most predominant in all cervical lesions, detected in 53.8%, 46.4%, and 38.9% of CC, HSIL, and LSIL, respectively. Among all HPV genotypes, HPV-16 and HPV-18 were found separately or together in 50% of LSILs, 60.7% of HSILs, and 76.9% of CC specimens. HPV-31 was the second most common type detected in LSILs (22.2%) and HSILs (21.4%). HPV-45 was the third most common type detected in CC (11.5%).

CONCLUSION

The prevalence and genotypes distribution patterns of HR-HPV types among patients with CC and its precursors in Jordan are similar to known international patterns. The results of this study provide baseline information on the HPV type distribution, which may guide the development of CC prevention and control programs in Jordan.
