Brief Summary
More than half of patients with esophageal cancer are inoperable because of late stage cancer or metastasis and they have to undergo palliative treatments. Dysphagia is the major symptom of patients with inoperable esophageal cancer. To relieve the dysphagia and improve the quality of life of such patients, stent placement has been widely accepted to be an option for palliation of the symptoms. However, recurrence of the neoplastic stricture remains a challenge after stent placement. To combine the advantages of the immediate relief of the esophageal dysphagia with the stent placement and radiation therapy with brachytherapy, a novel esophageal stent loaded with 125I seeds has been developed in the authors' institute. The preliminary clinical trial in a single institute has demonstrated better results than the conventional stent. This prospective multiple center trial is designed to further demonstrate the clinical outcomes with this irradiation, stent in patients compared to those using a conventional covered stent.

stenting
EXPERIMENTALThe conventional esophageal stent or 125I radiation stent is placed in the patients with dysphagia who are enrolled to the study.
Interventions
The esophageal stent combined a self-expandable covered esophageal stent and 125I radioactive seeds. Sheathes were attached to the outer surface of the stent, containing 125I radioactive seeds of CIAE 6711. The seeds were loaded into the sheathes on the stent immediately before implantation of the stent. The numbers and dose of the radioactive stent seeds was determined by the treatment plan system based on the size of the individual tumor. To cover the entire lesion of the tumor by the sheaths containing 125I seeds, at least 2 cm exceeding the tumor margins was required. The distance between the two sheaths was 15mm. In the control group, conventional covered esophageal stents were used which provided by the same company as those attached with 125I seeds.
