From the Guidelines
For LSIL with positive HPV, the recommended next step is colposcopy with directed biopsies. This approach is based on the most recent guidelines and evidence, which prioritize the identification of potentially serious lesions while minimizing overtreatment of low-grade abnormalities that may regress spontaneously 1. The management of LSIL with positive HPV involves a careful assessment of the risks and benefits of different approaches, considering factors such as the patient's age, the presence of high-risk HPV types, and the results of previous screening tests.
Key Considerations
- Colposcopy with directed biopsies is the recommended next step for LSIL with positive HPV, as it allows for direct visualization of the cervix and targeted sampling of abnormal areas 1.
- The risk of high-grade squamous intraepithelial lesion (HSIL) and cancer is estimated to be around 19% for LSIL with positive HPV, which justifies the use of colposcopy as a diagnostic tool 1.
- If the colposcopy is adequate and confirms only LSIL without evidence of higher-grade lesions, follow-up with repeat co-testing (Pap and HPV testing) in 12 months is appropriate rather than immediate treatment 1.
- For persistent LSIL with HPV positivity on follow-up testing, excisional procedures like LEEP (Loop Electrosurgical Excision Procedure) may be considered, especially in women over 25 1.
Management Approach
The management approach for LSIL with positive HPV should balance the need to identify potentially serious lesions with the risk of overtreatment of low-grade abnormalities. This approach should be individualized based on the patient's specific circumstances, including their age, medical history, and preferences. HPV vaccination should also be discussed if the patient hasn't completed the series and is within the recommended age range. By following this approach, healthcare providers can provide effective and personalized care for patients with LSIL and positive HPV, prioritizing their morbidity, mortality, and quality of life outcomes.

Next Steps in Management of LSIL with Positive HPV
- The management of women with low-grade squamous intraepithelial lesions (LSIL) and positive high-risk human papillomavirus (HR-HPV) diagnosis involves further evaluation to rule out high-grade lesions or cancer 2.
- According to the 2019 American Society for Colposcopy and Cervical Pathology (ASCCP) recommendations, women with a positive HR-HPV diagnosis and LSIL cytology result should be referred for colposcopy examination 2.
- However, the use of extended HR-HPV genotyping may improve the triage strategy for these women, potentially reducing unnecessary colposcopy referrals 2.
- Studies have shown that HR-HPV testing can be useful in triaging women with LSIL, especially in older women (>30 years) where the positive rate of HR-HPV is lower 3, 4, 5.
- The risk of high-grade squamous intraepithelial lesions (HSIL) is minimal in postmenopausal women with LSIL and a negative HR-HPV test, suggesting that repeat cytology after 12 months may be sufficient in these cases 4.
- HR-HPV testing has been shown to be useful in identifying women with LSIL who are at higher risk of developing HSIL, with a positive predictive value of 15-16% in HR-HPV positive cases 5.
- However, the high frequency of HPV positivity in women with LSIL limits the potential of HPV testing to direct decisions about clinical management 6.
Considerations for Clinical Management
- Colposcopy examination is recommended for women with HR-HPV positive LSIL, while repeat Pap test with cotesting may be sufficient for women with HR-HPV negative LSIL 5.
- The use of extended HR-HPV genotyping models, such as the HPV 16/18/31/33/52/58 genotyping model, may provide better efficacy in detecting HSIL lesions and reducing unnecessary colposcopy referrals 2.
- Clinical judgment and individual patient factors should be taken into account when determining the best course of management for women with LSIL and positive HR-HPV diagnosis.
