This study is being done to see if treatment for esophageal cancer can be done using endoscopy for patients ineligible for surgical or radiological therapy. The standard method of treating this type of cancer is surgical removal of the esophagus. The study will determine if removing just the cancer with endoscopy is enough treatment or if the addition of another treatment called photodynamic therapy (treatment with a red light and a drug called sodium porfimer) is needed.

Primary Outcome Measures:
  • To examine whether photodynamic therapy in addition to endoscopic mucosal resection will decrease cancer recurrence in early esophageal adenocarcinoma [ Time Frame: end of study ] [ Designated as safety issue: No ]
  • To identify biomarkers which identify patients who will respond to endoscopic therapy [ Time Frame: end of study ] [ Designated as safety issue: No ]
  • Evaluate the health related quality of life in patients undergoing endoscopic mucosal resection with and without photodynamic therapy [ Time Frame: end of study ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To assess biomarkers in the Barretts esophagus using cytology [ Time Frame: end of study ] [ Designated as safety issue: No ]

Arms Assigned Interventions
endoscopic mucosl resection
patients will undergo endoscopic mucosal resection at time of endoscopy if indicated
Procedure: Endoscopic Mucosal Resection
Endoscopic Mucosal resection at time of endoscopy if indicated
photodynamic therapy
patients will have endoscopic mucosal resection with photodynamic therapy
