Intervention / Treatment
Detailed Description
Primary Objective Pilot study of multichannel endoesophageal brachytherapy applicator to determine dose distribution and conformality of a 6 channel balloon repositioning applicator.
Secondary Objective(s)
- To collect data in order to show how the 6-tube endoesophageal brachytherapy technique will be an improvement (more conformed dose distribution) over a previously designed 3-tube endoesophageal brachytherapy technique in patients who are candidates for esophageal brachytherapy
- To evaluate acute toxicity of novel endoesophageal brachytherapy applicator.
Study Design
This innovative study will be an improvement over a previously designed 3-tube endoesophageal brachytherapy technique in patients who are candidates for esophageal brachytherapy. The brachytherapy planning process will utilize a novel multichannel balloon applicator.
The initial treatment session will occur after the patient has been found to be eligible, the consent form has been completed, and the treatment plan has been created. The patient will undergo subsequent weekly treatments for 3 to 6 weeks after the initial treatment.
The subject will be expected to participate in the trial throughout its entirety. The participation period is 6 months of which the patient will be evaluated and seen at months 3 and 6.
