초록
목적 : 전립선암 환자에서 외부 방사선치료의 효과 및 안전성을 평가하고 최적의 방사선치료 방법을 알아보고자 함이 본 연구의 목적이다. 재료 및 방법 : 1987년 9월부터 2000년 3월까지 본원에서 근치적 목적의 외부 방사선치료를 시행한 50명의 환자를 후향적으로 분석하였다. 요도관통 전립선 절제술 및 초음파를 이용한 조직검사를 시행하여 조직학적 진단을 확인하였다. 진단시의 주된 증상은 직장촉진시 전립선의 종괴 촉지, 빈뇨 및 급뇨, 소변시 통증호소 등이었다. 환자 나이의 분포는 51세부터 87세 이었고 중앙값은 63세이었다. A병기 환자는 6명, B병기 환자는 20명, C병기 환자는 26명, D1병기 환자는 8명이었다. 모든 환자는 10 백만볼트 에너지의 선형가속기를 이용하여 치료하였다. 4문대항 골반 상자 치료기법을 사용하여
Purpose : To evaluate effect and tolerance of external beam radiotherapy for carcinoma of the prostate and define the optimal radiotherapeutic regimen. Materials and methods : We retrospectively analyzed the records of 60 patients with prostate cancer who were treated with external beam radiotherapy with curative intent in our institution between September, 1987 and March, 2000. Histologic diagnosis was established by transurethral resection or ultrasonography guided biopsy. The major presenting symptoms were a nodule at routine prostatic examination and frequency and urgency of urination, along with dysuria. The median age was 63 years with range of 51 to 87 years. There were 6 patients in Stage A, 20 in Stage 8, 26 in Stage C, and 8 in Stage Dl. All patients were treated with megavoltage equipment producing 10 MV photons. The 4 field pelvic brick technique was used to a dose of 45 Gy or 50.4 Gy at 1.8 Gy per day in 5 to 6 weeks, after which a small boost field was delivered 2.0 Gy per day to a total dose of 66 to 70 Gy. The follow-up period ranged from 1 to 8 years. Results : Actuarial 5-year and 7-year survival rates for Stage A, B, C, and D1 were
