Clinical Trial Summary

The investigators conduct this phase II study to evaluate safety and effectiveness of EGCG in patients with dysphagia. Swallowing-related dysphagia and pain scores were recorded using the numerical rating scale (NRS) daily . Barium meal radiography was utilized to measure the luminal size and the length of the lesion area both before and after a week of EGCG treatment. The scales are translated into Chinese and guides in Chinese are developed instructing how to use the scales and perform the assessments.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Choking symptom objective response rate	Choking when swallowing was assessed by Stooler's dysphagia score (0-4, with 0 being none and 4 being completely unable to feed orally)	baseline and up to 7 days post-treatment
Primary	Pain symptom objective response rate	Pain when swallowing was assessed by numerical rating scale (0-5, with 0 being none and 5 being worst pain imaginable)	baseline and up to 7 days post-treatment
Primary	Imaging objective response rate	Response rate of esophageal stenosis was determined by X-ray barium meal examination and/or contrast-enhanced CT	Change from Baseline esophageal stenosis size at 7 days
Secondary	prealbumin change	The prealbumin values were tested by biochemical analysis	baseline and up to 7 days post-treatment
Secondary	Albumin change	The albumin values were tested by biochemical analysis	baseline and up to 7 days post-treatment
Secondary	Number of Participants with Adverse Events	participants will be followed for the duration of EGCG treatment	baseline and up to 7 days post-treatment
