Objective To investigate the efficacy and safety of photodynamic therapy （PDT） with topical 5-aminolaevulinic acid （ALA） on cervical condylomata acuminata. Methods Patients with cervical condylomata （n=30） were allocated into primary and recurrent group

and were given topical ALA under occlusive dressing for 3 hours followed by irradiation with semiconductor laser at a dose of 100 Jcm-2 and a power of 100 mW. The treatment was repeated 7 days later if the lesion was not completely removed after the first treatment. Complete response rate and recurrence rate of wart lesions as well as rate of adverse reaction were analyzed. Results The total complete response rate of PDT was 100% and the total recurrence rate was 5% after 3 months of follow-up. Recurrence rate of recurrent group was significantly lower than that of prior managements （100%

P<0.01）. The side effects of PDT in patients mainly included mild burning and/or stinging restricted to the illuminated areas

and was significant lower than their own control （25% vs. 100%

P<0.05）. Conclusion Compared with conventional therapies

topical application of ALA-PDT is a simple

effective

safe

well-tolerated

and low recurrence rate treatment for cervical condylomata acuminata.
