Clinical efficacy of photodynamic therapy

Abstract

OBJECTIVE: The management of cervical intraepithelial neoplasia (CIN) and early invasive cancer of the uterine cervix is very difficult to approach, especially in case of young woman who wants to preserve her fertility. Conization of the cervix may have various kinds of disadvantage. The objective of this clinical retrospective study is to investigate the therapeutic effects and clinical efficacy of photodynamic therapy (PDT) including combined chemo-photodynamic therapy in patients with pre-malignant CIN and malignant invasive cervical cancer. METHODS: energy was irradiated to the lesions. RESULTS: CIN 2 were 4 cases (18.2%) and CIN 3 were 15 (68.2%) and invasive cervical cancer were 3 (13.6%). Complete remission (CR) was found in 20 patients (91%). One case of 19 patients with CIN lesion recurred at 18 months after PDT treatment. CR was found in 18 cases in the patients with CIN lesions (95%). CR was found in 2 cases in the patients with invasive cervical cancer (67%). CONCLUSION: and relatively early invasive cancer of the uterine cervix. Combined chemo-photodynamic therapy is essential in case of invasive cervical cancer. For the young age group who desperately want to preserve their fertility and have a healthy baby, PDT can be a beacon of hope.
