Colposcopy High Grade Intraepithelial Lesions HSIL Dr Barbara Kerkhoff Consultant Gynaecologist & Obstetrician Bon Secours GP Study Day
High Grade Intraepithelial Lesion • Preinvasive lesion • Prevalence: 0.45% (USA) • 70 – 75% HSIL CIN 2/3 • 1 – 2% HSIL Invasive cancer Bon Secours GP Study Day
Treatment option • Excisional Techniques • LLETZ/ LEEP • Laser/ Knife cone biopsy • Local destructive Techniques • Laser Vaporisation • Cryotherapy • Diathermy • Cold Coagulation • Wedge biopsy (Pregnancy) • Hysterectomy Bon Secours GP Study Day
Success of LLETZ Free of disease 5 yrs • Low risk 92% < 50yrs, complete excision • Medium risk 86% < 50yrs, incomplete excision > 50yrs, complete excision • High risk 58% > 50yrs, incomplete excision Bon Secours GP Study Day
Causes of treatment failure Those women most likely to have persistent disease • Large volume disease • High grade disease • Incomplete excision • Immunosuppressed women Bon Secours GP Study Day
Treatment failure For every 1000 women treated for CIN: • 4 will develop invasive cancer - 5.8% for women treatment for CIN 3 Bon Secours GP Study Day
Why test for HPV? • High-Risk HPV DNA testing is more sensitive in detecting high grade disease than smear test.1 • A positive high-risk HPV result is an objective risk indicator for the development of high-grade disease and cancer.2 1.

Test of cure? Double negative (Smear and HPV DNA) over 2 years CURE! Nobbenhuis et all, Brit.J. Cancer 2001;84:796-801 Bon Secours GP Study Day
LLETZ or ablation Follow up guidelines Invasion CIN or CGIN r/v 6 month cytology and HPV Cytopath or MDT YES Negative cytology or HPV Positive cytology or HPV Repeat colposcopy +/- bx Repeat tx if required 2. r/v in 18 month Negative cytology or HPV Positive cytology or HPV no Cytological surveillance annual smears for 10 years d/c to routine screening Bon Secours GP Study Day
Core Messages to Patients • HPV is an infection, not a disease • HPV is not a marker for sexual behaviors, infidelity or timing of infection • HPV is very common • HPV is usually cleared by the immune system (90%) • HPV does not require tx in absence of CIN Bon Secours GP Study Day
Cervical cancer should be considered a very rare complication of a very common virus.Thank you! Dr Barbara Kerkhoff Consultant Gynaecologist Bon Secours GP Study Day
