Methods: Women with histologically confirmed CIN 1 in cervical biopsies were included in the prospective study. Participants of the study group used glycyrrhizinic acid spray (Epigen spray) topically 10 days (Epigen 10-day subgroup) or 20 days (Epigen 20-day subgroup) per month for 6 months. Women in the control group had no treatment. There were two follow-up visits 6 months apart. All patients were screened for human papillomavirus (HPV) before enrollment and during the first follow-up visit. Results: There were 50 patients in the Epigen group and 50 patients in the control group. At the first follow-up visit, in the histological findings, progression to CIN 2+ was 6.7% in the Epigen 20-day subgroup, 31.1% in the control group, and the persistence of CIN 1 was 86.7% in the Epigen 20-day subgroup and 62.2% in the control group, p = 0.03. Large loop excision of the transformation zone (LLETZ) was statistically significantly more frequent in the control group after the first follow-up visit (10% in the Epigen 20-day subgroup vs. 30% in the control group, p = 0.032). No such relationships were found during the second follow-up visit. Conclusions: The vaginal spray of the glycyrrhizinic acid used 20 days per month appears to decrease the risk of the progression of CIN 1 lesions, with the need to perform LLETZ. However, a similar effect is not observed after stopping usage.2297810enginfo:eu-repo/semantics/openAccesscervical intraepithelial neoplasiacervical precancerous diseasecolposcopyglycyrrhizinic acidhuman papillomavirus3.2 Clinical medicine1.1.
