HPV-Negative HSIL/CIN 2-3: Does It Eliminate Need for Colposcopy?
No, a negative HPV test does NOT eliminate the need for colposcopy and treatment in women aged ≥25 years with high-grade squamous intraepithelial lesion (HSIL) or CIN 2-3. Colposcopy with histological confirmation remains mandatory regardless of HPV status, though a negative HPV test provides reassurance about the absence of high-grade disease and may influence subsequent management decisions. 1, 2
Primary Management Algorithm
Initial Evaluation (HSIL Cytology)
Immediate colposcopy with endocervical assessment is recommended for all women with HSIL cytology, regardless of HPV test results. 1 The prevalence of CIN 2-3 in women with HSIL cytology is approximately 50%, making colposcopy non-negotiable. 1
Alternative option: An immediate diagnostic excisional procedure may be considered, especially for women at risk of non-compliance or those who have completed childbearing. 1
HPV testing does not alter management: Although HPV testing for HSIL is not formally included in guidelines, a negative test provides reassurance but does not eliminate the need for colposcopic evaluation. 1
Histologically Confirmed CIN 2-3
For Women Aged ≥25 Years
Treatment is the standard approach: Either ablation or diagnostic excision is acceptable when colposcopy is satisfactory. 1
Active surveillance may be considered in carefully selected patients who meet ALL of the following criteria: 1
- Willing and likely to comply with intensive monitoring every 6 months
- Squamocolumnar junction and upper lesion limit fully visible
- No immunosuppression
- No previous cervical treatment
- Multidisciplinary team review of cytology, colposcopy, and biopsy
Risk stratification for active surveillance: 1
- Higher progression risk (favor treatment): HPV 16/18 positive, HSIL cytology, large lesion size (>2 quadrants), expansile CIN, significant crypt involvement
- Lower progression risk (may consider surveillance): Other high-risk HPV types with ASC-US/LSIL cytology, normal cytology with non-16/18 HPV
Role of HPV Testing in CIN 2-3 Management
Post-treatment surveillance: HPV testing has superior negative predictive value (98%) compared to negative resection margins (91%) or cytology alone (93%) for detecting residual/recurrent disease. 1 Women who remain HPV-positive after treatment have significantly increased risk of recurrence. 1
Active surveillance protocol (if chosen): 1
- Co-testing or HPV testing with reflex cytology every 6 months
- Histological biopsy every 6 months if persistent/progressive disease suspected
- Continue until HPV-negative or decision to treat is made
Evidence Quality and Nuances
Strength of Recommendations
The 2025 British Society of Colposcopy and Cervical Pathology/European Society of Gynaecologic Oncology consensus statement 1 represents the most recent high-quality guideline, acknowledging that active surveillance is acceptable for selected CIN 2 patients aged ≥25 years, with no upper age limit if criteria are met.
However, the 2009 ASCCP guidelines 1 emphasize that observation of CIN 2-3 in non-adolescent, non-pregnant women is generally unacceptable, with treatment being the standard of care.
Research Evidence on HPV-Negative HSIL
A 2015 Korean multicenter study 3 found that only 8.8% of women with ASC-H (a less severe abnormality than HSIL) who were HPV-negative had CIN 2+ lesions, with no cases of invasive cancer. This suggests HPV-negative status substantially reduces risk, but this study examined ASC-H, not confirmed HSIL cytology or histological CIN 2-3.
A 2015 Japanese study 4 demonstrated that among women with HSIL/ASC-H cytology, even those testing negative for eight high-risk HPV types still had >35% risk of CIN 3+, warranting immediate colposcopy.
Critical Pitfalls to Avoid
Do not defer colposcopy based solely on negative HPV testing in women with HSIL cytology—the cytological diagnosis itself mandates evaluation. 1
Do not assume HPV-negative status eliminates cancer risk in women aged ≥25 years with confirmed CIN 2-3—approximately 12% of CIN 3 progresses to invasive cancer without treatment. 1
Do not offer active surveillance to immunosuppressed women or those with previous cervical treatment—these patients require definitive treatment. 1
Do not confuse management of adolescents/young women (<25 years) with older women—conservative management is preferred in younger women due to high regression rates (60-90%), but this does not apply to women ≥25 years. 1, 5
Ensure adequate colposcopy: If the squamocolumnar junction is not fully visible or colposcopy is unsatisfactory, diagnostic excision is recommended rather than observation. 1
Age-Specific Considerations
Women aged 25-40 years with CIN 2: A 2025 study 6 found 24.9% had occult CIN 3+ in excision specimens, with HPV 16/18 (OR 2.61) and HSIL cytology (OR 4.14) as independent risk factors. This supports treatment for most women in this age group, particularly those with these high-risk features.
Reproductive counseling: Women should be informed that preterm birth risk is lower if lesions regress spontaneously but higher if progression occurs and treatment is performed later. 1
