OBJECTIVE: To evaluate the efficacy and safety of 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT) and CO2 laser therapy of low-grade vaginal intraepithelial neoplasia (VAIN1) combined with high-risk human papillomavirus (hr-HPV) infection.

METHODS: A total of 163 patients with VAIN1 and hr-HPV infection were divided into PDT Group (n = 83) and CO2 laser Group (n = 80). The PDT Group received six times of ALA-PDT treatments and the CO2 laser Group received once CO2 laser treatment. HPV types, cytology, colposcopy, and pathological examinations were carried out before and after treatment. The differences in HPV clearance rate, VAIN1 regression rate, and adverse reactions between the two groups were analyzed during 6-month follow-up.

RESULTS: The overall HPV clearance rate of the PDT Group was significantly higher than that of the CO2 laser Group (65.06% vs 38.75%, P = 0.0008) although similar result was obtained for 16/18-related HPV infection patients (54.55% vs 43.48%, P = 0.4578). The VAIN1 regression rate of the PDT Group was significantly higher than that of the CO2 laser Group (95.18% vs 83.75%, P = 0.0170). In patients ≥ 50 years old, ALA-PDT showed better HPV clearance rate and VAIN1 regression rate than CO2 laser therapy (P < 0.05). The adverse reactions in the PDT Group were significantly lower than that in the CO2 laser Group (P > 0.05).

CONCLUSIONS: The efficacy of ALA-PDT appears better than CO2 laser for VAIN1 patients. However, the long-term effect of ALA-PDT for VAIN1 still needs to be explored. As a non-invasive treatment, ALA-PDT is a highly effective therapeutic procedure for VAIN1 with hr-HPV infection.
