## Abstract ## Background and Objective Polyhematoporphyrin (Photosan^ยฎ^) as sensitizers for photodynamic therapy (PDT) in advanced esophageal cancer carry the risk of prolonged photosensitivity of the skin. New sensitizers such as 5โaminolaevulinic acid (ALA) with low rates of skin phototoxicity
A cylindrical balloon was developed to improve delivery of circumferential light for photodynamic therapy (PDT) of esophageal carcinoma. The balloon consisted of a 36-mm-long clear cylindrical membrane and a central tube to hold a cylindrical diffuser in the center of the lumen. Three isotropic prob
Although delivery of uniform circumferential light is desirable during photodynamic therapy of advanced esophageal cancer in humans, early esophageal cancer may need only targeted treatment. Studies were performed in the canine esophagus of eight animals to investigate whether use of a "windowed" (s
