  • Purpose : This study was done to evaluate preliminarily the role of intraluminal brachytherapy in the radiation treatment of non-metastatic esophageal cancer, Materials and Methods: We analyzed follow-up result of 21 patients treated at the dept. of therapeutic radiology in Gyeongsang national university hospital between April, 1989 and August, 1992. All patients received neoadjuvant chemotherapy(5-FU, Cispl-atin). Fifteen Patients were treated with external beam alone, and in remaining 6 patients, the external beam radiotherapy followed by intraluminal brachytherapy was done. Results : Among 21 patients, 7 patients showed complete tumor regression after completion of radiotherapy. But 2 of these complete responder recurred at the site of primary disease, so ultimate local control rate was $23.8\%$(5/21). Local control rate according to radiation treatment modality was $6.7\%$(1/15) in patients treaed with external irradiation only, and $66.7\%$ in patients treated with combined external irradiation and intraluminal brachytherapy. The 2 year NED survival rate was $6.6.\%$ in the former and $66.7\%$ in the latter. Conclusion: Although there should be consideration about case selection for addition of intraluminal brachytherapy intraluminal brachytherapy may be considerded as one of the method to enhance the local control probability of esophageal cancer.
