Incidence and predictors of residual disease in women with high-grade squamous intraepithelial lesion (hsil) and positive margins after cervical loop electrosurgical excision
Background and Objective: Women who have
high-grade squamous intraepithelial lesion (HSIL) and
positive margins after an initial cervical loop
electrosurgical excision procedure (LEEP) carry a risk
of invasive cervical carcinoma if left untreated. This
study aimed to find factors predicting residual disease
in women with histologic HSIL and positive margins
after LEEP.
Methods: This retrospective cohort study was undertaken
among women with histologic HSIL who had
positive surgical margins following LEEP at Lamphun
Hospital between January 2014 and March 2020.
Factors predicting residual lesion were assessed by
univariate and multivariate logistic regression analysis.
Results: One hundred and thirteen women were included,
residual disease was found in 56 women
(49.5%). Multivariate analysis showed that only age
≥35 years (AOR = 10.8; 95%CI 1.1-109.8, p = 0.045)
and a large lesion on LEEP specimen (3-4 quadrants)
(AOR = 9.5; 95%CI 3.4-26.2, p <0.001) were significantly
independent factors associated with residual disease.
Conclusions: Age ≥35 years and large lesion are the
significant independent predictors for residual disease
in women who had HSIL with positive margins after
LEEP.
