Loop Electrosurgical Excision Procedure in Managing Persistent Low-Grade Abnormality or Human Papillomavirus...

Area of Science:

• Gynecology
• Cervical Cancer Screening
• Pathology

Background:

• Persistent low-grade cervical abnormalities or high-risk human papillomavirus (hrHPV) positivity necessitate careful management.
• Stratification based on previous high-grade results or HPV 16/18 status is crucial for risk assessment.

Purpose of the Study:

• To estimate the rate of high-grade abnormalities in women with persistent low-grade abnormalities or hrHPV positivity.
• To identify predictors of high-grade abnormalities in these patient groups.

Main Methods:

• Retrospective cohort study of patients undergoing loop electrosurgical excision procedure (LEEP).
• Patients stratified into low-risk and high-risk groups based on history of high-grade results or HPV 16/18 positivity.
• Logistic regression analysis to identify predictors of high-grade LEEP results.

Main Results:

• The rates of occult high-grade abnormalities were 12% in the low-risk group and 22% in the high-risk group.
• Younger age (25-29 years), current smoking status, and a history of high-grade abnormality were associated with increased odds of high-grade LEEP results.
• Approximately half of patients had abnormal cytology or hrHPV positivity at 2 years, regardless of LEEP findings.

Conclusions:

• A significant proportion of patients (12%-22%) with persistent low-grade abnormalities or hrHPV positivity have occult high-grade abnormalities on LEEP.
• Counseling on LEEP risks and benefits is essential, particularly for those with a history of high-grade dysplasia.
• Risk stratification aids in identifying patients who may benefit most from LEEP.
