Photodynamic Diagnosis for Early Stage Lung Cancer with Photofrin^|^reg; and Excimer dye laser Fluorescence Image Analyzer

Photodynamic Therapy With YAG-OPO Laser for Early Stage Lung Cancer

Photodynamic therapy (PDT) utilizing Photofrin is proving to be effective for the treatment of early stage lung cancers. The effect of PDT utilizing YAG-OPO laser as new light source was evaluated in 26 patients (29 lesions) with early stage lung cancers. YAG-OPO laser is solid state tunable laser which is easy to change wavelength between 620 and 670 nm exciting various kinds of photosensitize...

Photodynamic Therapy for Superficial Esophageal Cancer Using an Excimer Dye Laser

In order to improve the therapeutic effectiveness of photodynamic therapy with Photofrin II and laser light for superficial esophageal cancer, we employed an excimer dye laser instead of an argon dye laser. Eight superficial esophageal cancer lesions (7 cases) were treated. Of these 8 lesions, 6 were cured by initial treatment, while one lesion required another treatment. The final rate of cure...

Follow-up using fluorescence bronchoscopy for the patients with photodynamic therapy treated early lung cancer.

PURPOSE To evaluate the accuracy of fluorescence bronchoscopy by precise histological analysis of the photodynamic therapy (PDT) treated lesions. METHODS A retrospective study was conducted on thirteen patients (16 lesions) with centrally located early lung cancer (CLELC) had been undergone photodynamic therapy and had been followed up by fluorescence bronchoscopy. Fluorescence bronchoscopy w...

Our experience with photodynamic diagnosis and photodynamic therapy for lung cancer.

The diagnosis of lung cancer was significantly enhanced by the development of the fiberoptic bronchoscope in 1965. Since then, advances in photosensitizers and light sources have brought photodynamic medicine into the light. This article offers an historic overview of the emergence of photodynamic medicine through the perspective of a pioneer with more than 30 years' experience. Along with a di...
