Abstract
Purpose
To compare the cure rates between women who were treated with cold-coagulation versus large loop excision of the transformation zone (LLETZ) for cervical intraepithelial neoplasia grade 2 (CIN2) or 3 (CIN3) on pretreatment cervical punch biopsies.
Methods
This was a retrospective cohort study of women having had a single cervical treatment for CIN2 or CIN3 on pretreatment cervical punch biopsies between 2010 and 2011. The cure rates were defined as the absence of any dyskaryosis (mild/moderate/severe) on cytology tests during follow-up and were determined at 6 and 12 months after treatment.
Results
We identified 411 women having had cervical treatment with 178 cases of cold-coagulation and 233 cases of LLETZ. The cure rates at 6 months following cold-coagulation and LLETZ treatment were 91.6 versus 97.1% (p = 0.02), whereas at 12 months, they were 96.5 versus 97.3% (p = 0.76). Multivariable analysis showed that after adjusting for confounding factors, there was a fourfold higher cure rate with LLETZ in comparison with cold-coagulation at 6 months after treatment (adjusted OR 4.50, 95% CI 1.20–16.83; p = 0.026), with this difference disappearing at 12 months. The lower cure rates with cold-coagulation were due to its higher rates of mild dyskaryosis cytology tests at 6 months. The rates of moderate/severe dyskaryosis cytology tests were similar between the two treatment methods at 6 and 12 months.
Conclusion
We found that women with CIN2 or CIN3 on pretreatment cervical punch biopsies, after adjusting for multiple confounding factors, had higher cure rates when treated with LLETZ versus cold-coagulation at 6 months, with this difference disappearing at 12 months.
