What treatment is necessary for a 47-year-old female with a positive Human Papillomavirus (HPV) result and low-grade squamous intraepithelial lesion (LSIL) on her Pap test results?

Management of HPV-Positive LSIL in a 47-Year-Old Female

Colposcopy is the recommended management for a 47-year-old female with HPV-positive LSIL on Pap test results. 1

Initial Management

The presence of both HPV positivity and LSIL cytology requires a specific approach:

• Colposcopy is the standard recommended management for women with LSIL cytology, particularly when HPV-positive 1
• During colposcopy, any suspicious lesions should be biopsied, and endocervical assessment should be performed if colposcopy is unsatisfactory 2
• HPV testing is not typically recommended as a triage tool for LSIL (unlike ASC-US) because of the high prevalence of HPV in women with LSIL 1

Rationale for Colposcopy

The recommendation for colposcopy is based on several important factors:

• The ALTS trial demonstrated that LSIL cytology in adults is best managed with immediate colposcopy, as no useful triage strategy was identified 1
• Women aged 47 with HPV-positive LSIL have a significantly higher risk of having underlying CIN 2+ or CIN 3+ compared to HPV-negative LSIL 3
• The 5-year risk of CIN 3+ in HPV-positive/LSIL women is approximately 6.1%, which warrants immediate colposcopy 3

Management After Colposcopy

Management following colposcopy depends on the findings:

If Colposcopy is Satisfactory:

1. If biopsy shows normal findings or CIN 1:

   • Follow-up with either HPV DNA testing at 12 months or repeat cytology at 6 and 12 months 1, 2
   • If HPV testing is negative at 12 months or if cytology is negative at both 6 and 12 months, return to routine screening 2
   • If HPV testing is positive or repeat cytology shows ASC-US or greater, perform colposcopy again 2

2. If biopsy shows CIN 2 or CIN 3:

   • Treatment is indicated with one of the following: LEEP (Loop Electrosurgical Excision Procedure), cryotherapy, cold knife conization (CKC), or laser ablation 1, 2
   • CIN 2 may occasionally be followed without treatment in certain clinical circumstances (e.g., young women who desire fertility), but this is less likely to be appropriate for a 47-year-old woman 1

If Colposcopy is Unsatisfactory:

• Endocervical curettage (ECC) should be performed in addition to directed cervical biopsy 1
• Management will depend on the findings from both the cervical biopsy and the ECC

Important Considerations

• At age 47, the patient is at higher risk than younger women for persistent HPV infection and progression to higher-grade lesions 3
• Unlike in younger women where LSIL often regresses spontaneously, in women over 30 years, persistence is more common 1, 4
• HPV positivity among women with LSIL decreases only slightly with age (88% in women 30-34 years vs. 72% in women 60-64 years) 3
• The risk of progression from LSIL to HSIL is relatively uncommon (approximately 3% in confirmed cases), but requires careful monitoring 4

Follow-up After Treatment

• More frequent follow-up is needed after treatment due to higher recurrence rates 2
• Follow-up should include either HPV DNA testing every 12 months or repeat cervical cytology every 6-12 months 2
• If HPV test is positive or repeat cytology shows ASC-US or greater, colposcopy should be performed 2

Pitfalls to Avoid

• Avoid delaying colposcopy in this age group, as HPV-positive LSIL in women over 30 carries a higher risk of underlying high-grade disease 3
• Do not use HPV testing as a triage tool for LSIL, as the majority of women with LSIL are HPV-positive 1
• Excisional procedures (like LEEP) should not be performed without histological confirmation of CIN 2/3 2
• Do not assume that LSIL will spontaneously regress in this age group, as regression rates are lower than in younger women 1
