Abstrakt: Objective: The purpose of this study was to evaluate the role of HPV genotyping and previous cytology result to predict the evolution of CIN2 histological lesions managed conservatively.
Methods: A prospective observational study was conducted at Hospital del Mar in Barcelona from January 2012 to May 2017. Women with new diagnosis of CIN2 were invited to undergo conservative management for 24 months. Complete regression, partial regression, persistence and progression to CIN3 were defined as final outcomes. Univariate and multivariate analyses combining HPV genotyping and cytology were used to establish progression predictors of CIN2.
Results: A total of 300 patients were included in the study, and 291 patients completed the 24-months follow-up. Of them, 214 patients (73.5%) showed regression; 43 (14.8%) persistence to CIN2, and 34 (11.7%) progression to CIN3. In multivariable analysis, HPV-16 infection (odds ratio [OR] 1.97, [95% confidence interval {CI} 1.13-3.43]) and previous HSIL cytology (OR 3.46, [95% CI 1.99-6.02]) significantly increased the risk of persistence or progression (CIN2+) of CIN2 lesions. In contrast, all HPV-negative lesions regressed (p < 0.001).
Conclusions: The regression rate of CIN2 lesions supports conservative management in selected patients regardless of their age. Patients with a CIN2 biopsy and negative HPV test had a high rate of regression and should be offered follow-up without excisional treatment. In contrast, patients with HPV-16 and HSIL cytology had an increased risk of CIN2+, their treatment should be individualized and excisional treatment should be considered. The age may not be considered a criterion to decide the best management. New markers may help in the future to select the best management of CIN2.
