Clinical outcome of photodynamic therapy for the treatment of cervical intraepithelial neoplasia grade 2
Five-aminolaevulinic acid photodynamic therapy (ALA-PDT) was used to treat 79 cervical intraepithelial neoplasia 2 (CIN 2) patients who desired preservation of fertility ,between Oct 2018 and Dec 2020. Three months after treatment, among the 65 patients who returned for follow-up, full recovery and improvement rates were 43/65 and 16/65, respectively, resulting in a total response rate of 90.77%. This suggests that ALA-PDT is worthy of clinical application, even as monotherapy. The result of immune testing also indicated significant promotion of CD4+T expression during the recovery process, highlighting the importance of immune responses in different prognoses.
