Photodynamic therapy combined with recombinant human interferon α-2b gel for the treatment of male multiple anorectal condyloma acuminatum:a clinical observation

Objective To investigate the clinical efficacy and safety of 5-aminolaevulinic acid-photodynamic therapy(ALA-PDT) in treatment of anorectal condyloma acuminatum.Methods 95 cases who suffered from male multiple condyloma acuminatum were randomly divided into two groups.There were 50 cases in the treatment group and 45 cases in the control group.There were no statistically significant between two groups in age,sex,course of disease,skin lesions,the size and the distribution.The treatment group was treated by photodynamic therapy combined with recombinant human interferon α-2b Gel while the control group was treated only by photodynamic therapy.The treatment time lasted 7-10 days later if the Lesion was not completely removed.Totally,1-4 treatment sessions were given.Then the rate of recovery and recurernce of the two groups were compared.Results The recovery rate in treatment group was 94.0％ (47/50) and 88.9％ (40/45) were found in control group.There were no significant difference in the two groups (x2 =0.290,P ＞ 0.05) ;The recurernce rate of the treatment group was 2.0％ (1/50) and the control group was 13.3％ (6/45),the two groups had significant differences (x2 =4.457,P =0.035).Conclusion ALA-PDT combined with recombinant human interferon α-2b Gel in the topical treatment of anorectal condyloma acuminatum is safe and effective,whcih may serve a therapeutic option for anorectal condyloma acuminatum.
