Photodynamic therapy of Barrett's esophagus.
Photodynamic therapy seems to be able to control high-grade dysplasia within Barrett's esophagus about 80% of the time. Long-term results are not available, but the treatment is promising. Given the success with surgical intervention, however, use of photodynamic therapy should be reserved for nonsurgical candidates at the current time. The complications that occur with photodynamic therapy are...
متن کاملPhotodynamic Therapy for Barrett's Esophagus and Esophageal Carcinoma
This paper reviews the use of photodynamic therapy (PDT) in patients with Barrett's esophagus and esophageal carcinoma. We describe the history of PDT, mechanics, photosensitizers for PDT in patients with esophageal disease. Finally, we discuss its utility and limitations in this setting.
متن کاملPhotodynamic therapy (PDT)
Photodynamic therapy (PDT) is a comparatively novel therapeutic method involving a safe light source and a light-sensitive substance, termed as photosensitizers (PSs), such as methylene blue (MB), toluidine blue (TBO), sulfonated aluminum phthalocyanine, chlorine derivatives, nontoxic indocyanine green (ICG), and curcumin (CUR). (1) The combination of a nontoxic PS with low-intensity visible li...
متن کاملPilot study on light dosimetry variables for photodynamic therapy of Barrett's esophagus with high-grade dysplasia.
PURPOSE Photodynamic therapy (PDT) is used to treat Barrett's esophagus with high-grade dysplasia and mucosal carcinoma. Outcomes are variable with some patients having persistent disease, whereas others develop strictures. The aims of this study were (a) to compare porfimer sodium tissue uptake, light dose, and esophageal thickness with clinical outcomes and (b) to determine the selectivity of...
متن کاملPhotodynamic therapy (PDT) in Barrett's esophagus with dysplasia or early cancer.
OBJECTIVE Esophagectomy is the standard treatment for high-grade dysplasia (HGD) and intramucosal adenocarcinoma (IMC) arising within Barrett's esophagus. Results of photodynamic therapy (PDT) were retrospectively studied to evaluate the effectiveness of PDT in ablating HGD and/or IMC complicating Barrett's esophagus. METHODS Thirty-one patients unfit for or refusing esophagectomy (male: 20, ...
