Abstract
Purpose : To evaluate interim results in terms of failure, cosmetic results and survival after breast conserving operation and radiation therapy in early breast cancer. Material and Methods : From January 1992 through December 1997, seventy two patients with early stage 0, I and II breast cancer were treated with conservative surgery plus radiotherapy at Keimyung University Dongsan Medical Center. Age distribution was 25 to 77 years old with median age of 43. According to TNM stage, five patients had stage 0, thirty three were stage I, twenty five were IIa, and nine were IIb. Most patients underwent excision of all gross tumor and ipsilateral axillary dissection. Breast was irradiated through medial and lateral tangential fields of 6 MV photons to 50.4 Gy in 28 fractions over 5.5 weeks. We delivered a boost irradiation dose of 10 to 16 Gy in 1 to 2 weeks to excision site. Adjuvant chemotherapy was administered in forty one patients with CMF (cyclophosphamide, methotrexate, 5-fluorouracil) regimens of 6 cycles concurrently or before radiation. Cosmetic results were assessed by questionnaire to patients grading of excellent, good, fair, poor. Follow-up periods were 22 to 91 months with median 40 months. Results : Five year disease free survival rate (5YDFS) was
목적 : 초기 유방암 (병기 I, II)에서는 유방 보존 수술과 방사선치료가 선호 받고 있는 치료법이다. 본원에서는 1992년부터 이러한 방법을 시행 중이며 실패양상과 미용효과 및 생존률을 알아보고자 하였다. 대상 및 방법 : 1992년 1월부터 1997년 12월까지 계명대학교 동산의료원에서 유방 보존 수술과 방사선치료를 받은 초기 유방암환자 72명을 대상으로 하였다. 연령분포는
