title: Palliation of Dysphagia of Esophageal Cancer by Endoscopic Lumen Restoration Techniques.
abstract: BACKGROUND: Cure of patients with esophageal cancer has remained rare over the past four decades. The overall five-year survival rate for squamous cell and adenocarcinoma of the esophagus currently is reported as 12% in whites and 8% in blacks. The five-year survival rate for localized disease at initial staging is only 26% for whites and 13% for blacks. With regional involvement, these rates are 11% and 7%, respectively. METHODS: The author reviews the literature on optimal endoscopic lumen restoration techniques, including dilation, thermal laser and chemical ablation, photodynamic therapy, and stents. Procedures for pain relief and nutritional support are also presented. RESULTS: Lumen restoration to relieve dysphagia and provide the opportunity for sustaining reasonable peroral nutrition is an essential element in the overall management. Nonsurgical lumen restoration procedures have much to offer for dysphagia palliation and are briefly reviewed in this presentation. The major options include ablation of intraluminal tumor mass by thermal laser, photodynamic laser, chemical ablation, peroral dilation, and placement of esophageal stents. Most patients require more than one palliative method to sustain lumen patency during the course of their disease. CONCLUSIONS: Most patients with esophageal cancer will require palliation for the multiple problems that develop during their limited life span. The responsibility of the palliation therapist is to provide the patient with safe and cost-effective treatments that provide the best possible dysphagia relief.
