Effectiveness of therapy in women with cervical human papillomavirus infection: A systematic review and meta-analysis.

ObjectiveThis study evaluated the therapeutic efficacy of in women with cervical human papillomavirus infection. Specifically, it aimed to assess the impact of therapy on human papillomavirus clearance and cervical lesion resolution in clinical settings.MethodsA literature search was conducted in October 2024 using PubMed, EBSCO, Google Scholar, and ScienceDirect. Eligible studies included randomized controlled trials and quasi-randomized controlled trials investigating therapy for human papillomavirus infection. This review followed the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Risk of bias was assessed using the risk of bias 2.0 and ROBINS-I (Risk Of Bias In Non-randomized Studies - of Interventions) tools. Data were analyzed using a random-effects model with 95% confidence intervals, and heterogeneity was evaluated using the statistic. A subgroup analysis was performed based on the method of administration (oral vs. vaginal).ResultsFive studies were included in the meta-analysis. Among 326 participants assessed for lesion resolution, therapy showed a statistically significant improvement (relative risk = 1.93, 95% confidence interval: 1.47-2.53, p < 0.00001;  = 0%). Similarly, among the 262 participants assessed for viral clearance, the treatment showed a statistically significant effect (relative risk = 1.39, 95% confidence interval: 1.00-1.94, p = 0.05;  = 33%).ConclusionIn patients with low-grade squamous intraepithelial lesions/atypical squamous cells of undetermined significance cervical lesions, therapy administered over a minimum duration of 6 months may serve as an adjuvant treatment for human papillomavirus infection.
