BACKGROUND: Human papilloma virus (HPV) infection and cervical condyloma acuminatum (CA) often co-exist. Although there are many methods to treat cervical CA, high recurrence rate and cervical scars are still troublesome. Biopsy forceps excision combined with 5-aminolevulinic acid photodynamic therapy (ALA-PDT) is a feasible approach for cervical CA, but its efficacy and limitation need to be evaluated.
METHODS: This retrospective study consisted of 49 patients aged 18-50 years with a histologically or colposcopic confirmed cervical CA and with HPV infection. Patients were treated with biopsy forceps excision and ALA-PDT. The efficacy was evaluated through HPV typing and colposcopy directed biopsy.
RESULTS: Three months after the combination treatment the total lesion remission rate was 93.88 % (46/49) and the HPV clearance rate was 83.67 % (41/49). One patients showed some residual lesions and two patients showed new lesions. Recurrence rate was 4.34 % at 6 months follow-up. There was no significant difference in HPV clearance rate at 3 and 6 months follow-up. Univariate analysis showed that the combination treatment was less effective for patients who had size of visible lesion > 1.5 cm2. Adverse effects were minimal and no structural complications were reported. The main side effects were abdominal pain and increased vaginal secretions.
CONCLUSION: Combination of biopsy forceps excision and ALA-PDT is safe and effective for eliminating cervical condylomata lesion and eradicating HPV infection. Colposcopic evaluation is recommended before and after treatment.
