ABSTRACT
Photodynamic therapy (PDT) is proved effective for treating low-grade squamous intraepithelial lesions (LSIL) and condylomata acuminata (CA). 5-Aminolevulinicacid (5-ALA) is the most common applied photosensitizer, but high rate of unbearable pain and relative long incubation time were reported. Here, we report a 27-year-old woman suffering from cervical and vaginal giant CA with LSIL involving the whole right vaginal fornix, cervical surface, and vaginal wall. Holmium yttrium aluminum garnet (Ho YAG) laser was first applied to remove the giant CA lesions. STBF, a derivative of chlorin e6 (Ce6) was then applied on suspicious lesions as a new photosensitizer for 1 h. Lesions were exposed to LED illumination with a wavelength of 630 nm and light dose of 200-284 J/cm2 for cervical canal and the vaginal surfaces, 100-150 J/cm2 for cervix surface. Vaginal giant CA and LSIL lesions got complete remission at 6-month follow-up. Mild tolerable adverse reactions were observed after STBF-PDT and relieved in 24 h. Thus, the combination of Ho YAG laser and STBF-PDT may be a novel option for cervical and vaginal giant CA and LSIL, especially for special vaginal fornix areas.
