Summary

This study looks at whether adding a special balloon-based internal radiation treatment after standard chemoradiation can lower the chance of the tumor coming back in people with esophageal cancer who chose not to have surgery. About 18 adults aged 20-85 with stage I-III esophageal cancer will receive this extra radiation. The goal is to improve local tumor control while reducing side effects like fistulas or narrowing of the esophagus.

Inclusion Criteria: 1. Age of 20-85 years, with ECOG performance 0-2 2. Thoracic esophageal cancer with clinical stage I-III and biopsy proof; patient with cervical esophageal cancer or stage IV thoracic esophageal cancer could be recruited in this trial according to Investigator's assessment. 3.

Patient whose tumor is resectable but declined to receive surgery after first course CCRT. Exclusion Criteria: 1. T4b tumor status (tracheal / bronchial mucosa, aortic involvement, or fistula formation). 2. Stenosis of esophageal lumen that cannot be bypassed by the applicator. 3.
