Management of HSIL with Positive High-Risk HPV
Immediate Colposcopy is Mandatory
A 36-year-old woman with HSIL cytology and positive high-risk HPV must undergo immediate colposcopy with directed biopsy, as this combination carries a very high risk of underlying high-grade cervical intraepithelial neoplasia (CIN 2/3) or invasive disease. 1
Primary Management Algorithm
Step 1: Immediate Colposcopic Evaluation
- Colposcopy should be performed without delay for all women with HSIL cytology, regardless of HPV status, due to the substantial risk of underlying CIN 2/3 or invasive cancer. 1
- During colposcopy, the cervix should be examined with 10x-16x magnification after application of 3-5% acetic acid solution to identify abnormal areas requiring biopsy. 2
- Colposcopically directed biopsies must be performed on all suspicious areas to rule out invasive disease and determine the extent of preinvasive disease. 2
- If the entire squamocolumnar junction is not visualized (unsatisfactory colposcopy), endocervical curettage should be performed. 1, 2
Step 2: Expedited Treatment Option
- For non-pregnant patients aged ≥25 years with HSIL and positive HPV 16, expedited treatment (see-and-treat) may be considered as an alternative to colposcopy with biopsy, based on the extremely high risk of underlying high-grade disease. 3, 4
- This approach allows for immediate excisional treatment at the time of initial colposcopy without waiting for biopsy confirmation, reducing the number of procedures and potential loss to follow-up. 3
Step 3: Management Based on Biopsy Results
If CIN 2/3 is confirmed:
- Treatment with excisional procedure (LEEP or cold-knife conization) is recommended. 2
- For CIN 2 in younger women desiring fertility preservation, observation may be considered, though this is less applicable at age 36. 2
- For CIN 3, treatment with excisional procedure is mandatory. 2
If biopsy shows only CIN 1 or is negative despite HSIL cytology:
- This represents a significant discordance that requires careful evaluation. 1
- Endocervical curettage should be performed if not already done. 1, 2
- Repeat colposcopy or diagnostic excisional procedure (LEEP) may be warranted given the high-grade cytology. 1
Evidence Strength and Clinical Context
- The positive predictive value of HSIL cytology for underlying CIN 2/3+ is approximately 90.5% when hrHPV is positive, making immediate intervention essential. 5
- In women with HSIL cytology, 89.3% test positive for high-risk HPV, and the combination significantly elevates risk. 5
- HPV 16 is present in 61% of invasive cervical carcinomas and 68% of severe dysplasias, making HPV 16-positive HSIL particularly concerning. 6
Critical Pitfalls to Avoid
- Never delay colposcopy for repeat cytology or HPV testing when HSIL is diagnosed—this is the most serious cytologic abnormality short of invasive cancer. 1
- Do not rely on negative hrHPV testing to downgrade management if HSIL cytology is present; approximately 8.3% of morphologically diagnostic HSIL cases may be hrHPV negative by standard testing but still harbor high-grade disease. 7
- Do not perform HPV genotyping before colposcopy—colposcopy is indicated regardless of specific HPV type when HSIL is present. 4
- Endocervical curettage is contraindicated in pregnancy, though colposcopy should still be performed. 4, 2
