What is the recommended follow-up for a female of reproductive age with a normal Pap (Papanicolau) test result and a positive Human Papillomavirus (HPV) test result, but negative for high-risk types 16, 18, and 45?

Recommended Follow-Up for Normal Pap with HPV-Positive (Non-16/18/45) Result

Repeat Pap and HPV cotesting in 1 year is the recommended management for a woman of reproductive age with normal cytology and positive high-risk HPV that is negative for types 16,18, and 45. 1

Management Algorithm

The 1-year follow-up interval is specifically indicated for this clinical scenario:

• Women with normal Pap smears but positive high-risk HPV (excluding types 16,18, and 45) should undergo repeat testing in 1 year with HPV testing with or without concurrent Pap 1
• This recommendation is based on the 2021 CDC STI Treatment Guidelines and 2019 ASCCP Risk-Based Management Consensus Guidelines 1
• The presence of non-16/18 high-risk HPV types with normal cytology carries lower immediate risk for CIN3+ compared to HPV 16/18 positivity 2, 1

What Happens at the 1-Year Follow-Up Visit

Testing options and subsequent management:

• The preferred approach is HPV testing with or without concurrent Pap, rather than cytology alone, as HPV testing provides superior disease detection 1
• If both tests are negative at 1 year, return to routine 3-year screening intervals 1
• If HPV remains positive or cytology becomes abnormal, refer for colposcopy 1

Why Not Immediate Colposcopy

Colposcopy is not indicated in this scenario because:

• HPV types 16 and 18 are the only genotypes that warrant immediate colposcopy despite normal cytology, as they carry the highest risk for CIN3+ 1
• Your patient tested negative for HPV 16,18, and 45, placing her in a lower-risk category 1
• Many HPV infections clear spontaneously within 12-24 months, particularly in younger women of reproductive age 1

Why Not 3-Year or 5-Year Intervals

Longer intervals are inappropriate for this result:

• Five-year intervals are only appropriate for women aged 30 years and older with completely negative cotesting (both Pap and HPV negative) 3, 4
• Three-year intervals apply to women with resolved HPV infections (previously positive, now negative) or those with negative cotesting who are under age 30 3
• A single HPV-positive result with normal cytology requires closer surveillance than completely negative results 1

Risk Stratification Context

Understanding the risk level:

• Persistent HPV positivity at 1 year significantly elevates risk and warrants colposcopy 1
• Type-specific persistent infections carry a 10-year cumulative CIN3+ risk of 20.4%, while new infections carry only 3.4% risk 5
• About three-quarters of women with HPV infection and normal cytology clear their infections within approximately 3 years 5

Common Pitfalls to Avoid

Key management errors to prevent:

• Do not extend the screening interval beyond 1 year for HPV-positive women with normal cytology, even though immediate risk is relatively low 1
• Do not perform HPV 16/18 genotyping for women who already have normal cytology with non-16/18 HPV, as it does not alter management 2
• Do not confuse this scenario with HPV-negative/ASC-US results, which require 3-year follow-up 4
