Paper Abstract

Photodynamic therapy has been established as an alternative treatment for patients with Barrett's esophagus with dysplasia or early superficial cancer. Twenty-three patients have been treated and followed for 6 - 54 months. Twenty-one patients had high grade dysplasia and 2 had low grade dysplasia. Ten patients had early cancer (Tis-T1) and 1 had T2 cancer. All patients were maintained on omeprazole after treatment. Three separate PDT treatments were required in 2 patients, 2 in 5 patients and 1 in 16. Dysplasia and carcinoma were eliminated in all. Seventy-five to eighty percent of Barrette's mucosa was replaced by squamous epithelium. One patient developed a new carcinoma in an area of dysplasia treated 3 months earlier and was retreated successfully. Two patients developed new areas of dysplasia in untreated segments of the Barrett's esophagus, requiring a separate treatment. Twelve patients developed strictures, all responding well to dilatation.
