One Case of Esophageal Cancer Treated with High Dose Rate ICR

고 선량률 강내 치료기를 이용한 식도암 치험 1례

Esophageal cancers are highly malignant neoplasms. Prognosis of esophageal cancer treated by external irradiation alone is rather poor because of local recurrence and distant metastasis. Recently intracavitary irradiation has been used as a boost therapy after external irradation to optain better local control. One case of esophageal cancer has been treated by high dose rate remote-controlled afterloading unit as boost therapy after external irradiation. The result was excellent in short term follow up esophagogram but esophageal bleeding and esophagotracheal fistula were noted in further follow up examination after inappropriate posttreatment management including insufficient chemotherapy due to poor general condition. We reviewed possible causes of esophageal bleeding and esophagotracheal fistula after external irradiation and high dose rate ICR.

식도암 환자에서 외부 방사선 치료와 고 선량률 강내 치료를 병용하여 자각 증상의 호전은 물론 식도 촬영상에서도 좋은 반응을 보인 환자에서 장기간이 경과후에 발생한 식도 출혈과 식도 기관루를 경험하였기에 문헌 고찰도 함께 하였다
