Summary
Brief summary (as posted)
Current therapies for Adenocarcinoma of the Esophagus provide limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of Adenocarcinoma of the Esophagus. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Adenocarcinoma of the Esophagus.
