Management of Positive HPV Test Results
When primary HPV testing returns positive, perform reflex cytology on the same specimen to determine next steps, with immediate colposcopy required for HPV 16/18 or high-grade cytology, while other positive results can be managed with 1-year follow-up if cytology is normal and recent prior screening was negative. 1, 2
Immediate Colposcopy Required
The following scenarios mandate immediate colposcopy referral:
HPV 16 or 18 positive: Proceed directly to colposcopy regardless of cytology results, even if Pap test is completely normal 1, 2
High-grade cytology: Any HSIL or ASC-H result requires colposcopy 1, 2
- For nonpregnant patients ≥25 years with HSIL and HPV 16, expedited treatment is preferred over colposcopy with biopsy 1
Two consecutive positive HPV tests: Colposcopy is always recommended regardless of previous Pap results or cytology findings 1, 2
History of high-grade lesions: Patients with prior CIN 2/3, HSIL, ASC-H, AGC, or AIS may warrant colposcopy even with current normal results 1
Deferred Colposcopy: 1-Year Follow-Up Strategy
For HPV-positive results (non-16/18 types) with normal cytology, return in 1 year is appropriate if the patient had negative HPV test or cotest within the past 5 years for screening purposes 1, 2:
- This deferral strategy applies to minimally abnormal results: NILM HPV-positive, ASC-US HPV-positive, or LSIL 1
- At 1-year follow-up, perform HPV testing or cotesting (preferred over cytology alone) 1
- Refer to colposcopy if cytology is abnormal or HPV test remains positive at the 1-year visit 1, 2
Critical caveat: A negative HPV test performed during surveillance of a previous abnormal result does NOT reduce risk sufficiently to defer colposcopy—only negative screening tests within the past 5 years qualify 1
Practical Implementation for Primary HPV Screening
When using primary HPV testing as the screening modality 1:
- Cytology testing should be performed as a reflex test from the same specimen by the laboratory to avoid requiring patient return 1, 2
- If reflex cytology is not feasible and the patient cannot easily return, consider colposcopy directly 1
- HPV genotyping for types 16 and 18 should be performed to guide management 1
Follow-Up Testing Intervals
The frequency of surveillance differs based on testing method 1:
- HPV testing or cotesting: Recommended at 3-year intervals for routine follow-up 1
- Cytology alone: Recommended annually when HPV/cotest would be done at 3-year intervals 1
- More intensive surveillance: Cytology at 6-month intervals when HPV/cotest would be done annually 1
Post-Treatment Surveillance for High-Grade Precancer
After treatment for CIN 2/3 or moderate-to-severe dysplasia, surveillance must continue for at least 25 years 1, 2:
Initial testing: HPV test or cotest at 6,18, and 30 months post-treatment 1, 2
- If using cytology alone: test at 6,12,18,24, and 30 months 1
Long-term surveillance: After completing initial testing, continue at 3-year intervals with HPV/cotest or annually with cytology alone 1, 2
Duration: Continue for at least 25 years even if this extends beyond age 65 years 1, 2
Post-hysterectomy: If hysterectomy occurs during surveillance period, vaginal screening should continue 1
Common Pitfalls to Avoid
- Do not use HPV testing in patients <25 years: HPV testing is not recommended for routine cervical cancer screening in this age group 1, 3
- Do not test for low-risk HPV types: Testing for nononcogenic types (e.g., types 6 and 11) is not recommended 1
- Do not use HPV testing for: Deciding whether to vaccinate, managing genital warts, or testing oral/anal specimens 1, 3
- Ensure FDA-cleared tests: Only use FDA-cleared HPV tests for their approved indications (Cobas 4800 and Onclarity for primary screening; others only for cotesting or triage) 1
