Remote Afterloading hish Dose Rate (HDR) Endobronchial Brachytherapy

기관지 폐색으로 호흡곤란을 유발하는 기관지내 악성종양을 치료하기 위한 방사선 치료방법으로 고선량 기관지내 근접치료법이 본원에서 시행되었다. 기관지 내시경 수술을 이용하여 근접치료용 관을 기관지 내로 삽입하여 microSelection HDR Ir-192를 이용하여 고선량 근접치료를 시행하였다. 이논문에서 저자들의 경험을 소개하고 이 새로운 근접치료 시술이 효과적이면서도 외래 환자로 통근 치료도 가능할 정도로 용이하고 안전한 치료법으로 자세한 기술적인 점을 설명하고자 한다.

Authors described the remote afterloading endobronchial brachytherapy(EBBT) technique using the microSelectron HDR Ir-192 and the Asan Medical Center experience. Total 28 EBBT in 9 patients were performed since November 1989 and 24 EBBT in 8 patients were emploiyed for palliation and 3EBBT in 1 aptient was treated curatively. Authors observed a significant relief of obstructive symptom with tumor regression in 7 patients out of 8 who were treated palliatively but one of them died of pulmonary congestion in 3 weeks after EBBT. One patient with prior therapy of extensive electrocautery expired within 1 day after 2nd EBBT procedure with massive hemorrhage from the lesion. EBBT procedure has been tolerable and can be performed as an outpatient.
