Esophageal Carcinoma Treated with Proton Beam
The prognosis of patients with esophageal carcinoma treated by external x-ray irradiation alone is poor because of local recurrence and distant metastasis , To solve this problem, we have adopted a new therapeutic modality which utilizes proton beam. Proton beam has a highly defined dose distribution, resulting in no radiation exposure beyond the beam range and very little side scatter [2–4]. Thus, a study has been undertaken at the Institute of Clinical Medicine, University of Tsukuba in patients with esophageal carcinoma to receive definitive proton therapy or proton beam irradiation following external x-ray irradiation. This report describes the preliminary results from the first 15 patients who have been so treated.
