ABSTRACT
OBJECTIVE:
To investigate the clinical efficacy of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) for cervical high-risk HPV (HR-HPV) infection.METHODS:
In this prospective study, a total of 76 patients with persistent cervical HR-HPV infection were randomly divided into two groups. The treatment group (39 patients) received three treatments of ALA-PDT at two-week intervals. The control group (37 patients) received no treatment. All patients were followed up for 9 months. Hybrid Capture HPV DNA Assay and ThinPrep cytology test (TCT) were performed for both groups. Patients with abnormal TCT results received colposcopic biopsy before treatment and during follow-ups.RESULTS:
HR-HPV remission rates were 64.10% (25/39) in the treatment group and 24.32% (9/37) in the control group at 3 month follow-up. Complete remission rates were 76.92% (30/39) and 32.40% (12/37), respectively, in the two groups at 9 month follow-up. There was a statistically significant difference between the two groups (P<0.01). Conversion rates of abnormal TCT results were 81.81% (9/11) in the treatment group and 12.50% (1/8) in the control group at 3 months, and 90.90% (10/11) and 25.00% (2/8), respectively, at 9 months. Five of six patients with CIN I in the treatment group and no patients in the control group achieved complete response at 9 months. There was a statistically significant difference between the two groups (P<0.01).CONCLUSION:
Topical ALA-PDT is an effective, safe and well tolerated treatment for cervical HR-HPV infection.Palavras-chave
