Abstract:
Effect of Photodynamic therapy (PDT) for esophageal cancer was discussed in this study. PDT has been performed on 9 cases of superficial esophageal cancer. All cases were followed periodically by endoscopy for 2 years 2 months to 6 years and no case has any local recurrence. But in 2 cases invaded submucosal layer, lymph node metastasis was recognized. We think PDT is one of the very effective therapies in the treatment of intramucosal cancer.
