Risk factors analysis of recurrent disease after treatment with a loop electrosurgical excision procedure for high-grade cervical intraepithelial neoplasia.


ABSTRACT:

Objective

To evaluate the risk factors of recurrent high-grade cervical intraepithelial neoplasia grade 2 or worse (CIN2+) after loop electrosurgical excision procedure (LEEP).

Methods

This retrospective study included patients with histopathologically confirmed CIN2/3 who underwent LEEP in 2015-2020. Cox regression analysis was used to evaluate the risk factors of recurrence.

Results

Recurrent CIN2+ was found in 268 patients after LEEP (268/4369, recurrence rate, 6.1%). High-risk (hr-) HPV infection (hazard ratio [HR] 12.09, 95% confidence interval [CI] 7.78-18.79), margin status (HR 6.48, 95% CI 4.75-8.84), baseline diagnosis (HR 1.45, 95% CI 1.08-1.95), smoking (HR 3.17, 95% CI 2.27-4.43), and immunosuppression (HR 1.96, 95% CI 1.33-2.91) were significant independent risk factors of recurrence. HPV16 (HR 3.61, 95% CI 2.43-5.37), HPV33 (HR 2.62, 95% CI 1.12-6.12), and HPV52 (HR 1.61, 95% CI 1.02-2.55) infection showed a higher risk of recurrence. High-risk HPV had the highest accuracy (sensitivity 88.5%; negative predictive values 98.7%) in predicting recurrence compared with liquid-based cytology test and margins.

Conclusion

Given that positive margins present a higher risk, wide excision may be required to avoid residual lesions. More attention should be paid to the correlation between recurrence and hr-HPV genotypes. After treatment for high-grade CIN, HPV-based testing is recommended at 6 months. Timely identification of high-risk factors enables risk stratification, and enables individual management or individual follow-up and recall strategies.
