Photodynamic therapy using talaporfin sodium (Laserphyrin®) for bile duct carcinoma: a preliminary clinical trial.

چکیده
The efficacy of adjuvant photodynamic therapy (PDT) using the new photosensitizer, talaporfin sodium (TPS), was assessed in 7 patients with bile duct carcinoma (BDC). The 664-nm semiconductor laser (100 J/cm(2)) was applied through endoscopy to the tumor lesion within 6 h after injection of TPS. Cases included three non-resectable and 4 resected BDC with remnant cancer cells at the bile duct stump. Radiated lesions exhibited mild inflammatory responses. Locally advanced tumor occluding bile duct was relieved by PDT and patency was maintained for 16 months. Two patients developed mild photodermatitis but no severe morbidity. One patient died of other disease, and two patients died of liver metastasis within 6 months, but local recurrence was not observed. Three patients maintained cancer-free survival for 6-13 months. One patient survived with good status for 24 months. Adjuvant TPS-PDT is a safe and useful treatment for local control of BDC. Compared to the conventional PDT, the patient's quality of life is remarkably improved.

Current Status of Photodynamic Therapy in Digestive Tract Carcinoma in Japan
Photodynamic therapy (PDT) is an effective local treatment modality as a cancer-specific laser ablation in malignancy of some organs including digestive tracts or bile duct. In Japan, PDT has been applied at the early period after the first clinical induction in 1980's. Although the useful efficacy was clarified, PDT has not been fully applied because of the phototoxicity of the porfimer sodium...

BACKGROUND Treatment failure at the primary site after chemoradiotherapy is a major problem in achieving a complete response. Photodynamic therapy (PDT) with porfimer sodium (Photofrin®) has some problems such as the requirement for shielding from light for several weeks and a high incidence of skin phototoxicity. PDT with talaporfin sodium (Laserphyrin) is less toxic and is expected to have a ...

BACKGROUND Mono-L-aspartyl chlorin e6 (Talaporfin sodium) is a novel photosensitizer, and is currently being used in photodynamic therapy for various malignant tumors in combination with irradiation with a 664 nm laser. An interesting characteristic of Talaporfin sodium is that the skin photosensitivity after injection of this agent disappears faster than any other existing photosensitizers. Th...
