Progression of cervical intraepithelial neoplasia grade 2 lesions among Japanese women harboring different genotype categories of high-risk human papillomaviruses
Background: This study aimed to examine whether genotype categories of high-risk human papillomaviruses (HR-HPVs), when divided into HPV16/18, HPV 31/33/45/52/58, and HPV35/39/51/56/59/68, had an effect on the time required for and the proportion of cases that progressed to cervical intraepithelial...

description | Background: This study aimed to examine whether genotype categories of high-risk human papillomaviruses (HR-HPVs), when divided into HPV16/18, HPV 31/33/45/52/58, and HPV35/39/51/56/59/68, had an effect on the time required for and the proportion of cases that progressed to cervical intraepithelial neoplasia (CIN) grade 3 among women with CIN2. Patients: A total of 160 women aged 20–49 years and having CIN2 were recruited between January 2008 and June 2018. The time required for progression to CIN3 was determined by Kaplan-Meier time-to-event analysis. HPV genotypes were determined using the Linear Array HPV genotyping test. Results: During an average follow-up time of 22 months, 62 (39%) women with CIN2 progressed to CIN3, whereas 34 (21%) eliminated HR-HPVs and became cytologically normal. The majority (63%) of the women harboring HPV16/18 progressed to CIN3 with a 50% progression time of 11 months, whereas 26% of those harboring HPV31/33/45/52/58 progressed to CIN3 with a 50% progression time of 70 months. Conclusion: For every patient diagnosed with CIN2, genotyping to distinguish HPV16/18 from other HR-HPVs should be performed. Therefore, electing a surgical treatment, such as conization, should be considered as the primary option for women who are positive for HPV16/18, particularly when they are likely to be lost for follow-up or are 40 years old or older. In contrast, follow-up cytology should be repeated every 12 months for women harboring non-16/18 HR-HPVs. Those who tested negative for HR-HPV may be followed at the maximum interval of 24 months. |
