A Study To Examine Quality of Life Assessment in Patients Receiving Cryotherapy for Palliation of Dysphagia in Unresectable Esophageal or Gastroesophageal Junctional Cancer


About this study

The purpose of this study is to determine the effect of endoscopic cryoablation for lessening the effects of dysphagia on the quality of life (QOL) of patients with unresectable esophageal or gastroesophageal junctional cancer.
