Abstract
Photodynamic therapy using Photofrin has been used as an alternative to esophagectomy for patients with dysplasia or superficial cancer associated with Barrett's esophagus. In this update we present the results in 71 patients treated and followed for 6-72 months. 54 patients had high grade dysplasia/early cancer, and 17 had low grade dysplasia. 22 Patients had early cancer and 1 had T2 cancer. Three separate PDT treatments were required in 3 patients, 2 in 20 patients and 1 in 48. All patients were maintained on omeprazole. Patients received a photofrin dose of 2 mg/kg followed two days later by 630 nm laser light from an either argon/dye laser or KTP/dye laser. The majority of patients received light from a balloon light delivery device. Dysplasia and carcinoma was eliminated or reduced in majority of the cases. 75-80 percent of Barrett's mucosa was replaced by squamous epithelium. 34 patients developed strictures. All responded well to dilation.
