목적 : III기 비소세포성 폐암으로 근치적 방사선치료를 받은 환자의 생존율과 예후인자를 알아보기 위하여 본 연구를 시행하였다. 방법 : 1991년 1월부터 1993년 12월까지 비소세포성 폐암으로 강동성심병원 치료방사선과에서 45 Gy 이상의 근치적 방사선치료를 시행 받았던 35명의 환자에 대한 치료 결과를 후향적으로 분석하였다. 병기별 환자의 분포는 IIIA 15 명, IIIB 20 명이었다. 방사선 치료는 6 MV X-선을 이용하여 일일선량 1.8 Gy-2 Gy씩 주 5 회 조사하여 48.4-66.6 Gy (중앙값 61.2 Gy)까지 치료하였다. 9명의 환자에서 유도화학요법, 1명의 환자에서 동시화학요법이 시행되었고 대부분이 FIP(5-FU, ifosfamide, cisplatin) 복합화학요법을 시행받았다. 결과 : 전체 환자의 중앙생존기간은 6개월이었으며 1년 생존율은 23.3%, 2년 생존율은 6.7%이었고 병기에 따른 중앙생존기간은 IIIA 8개월, IIIB 5.5개월 이었다. 항암화학요법을 시행한 10명의 중앙생존기간은 11개월, 1년 생존율은 60%이었고 방사선 단독 치료의 경우는 중앙 생존기간이 5개월, 1년 생존율이 9%로 통계학적으로 유의한 차이가 있었다 (p=0.03). 생존율에 영향을 미치는 예후 인자는 총 방사선량, 치료 1개월 후의 반응, 치료후의 전신상태이었으며 연령, 성별, 치료전 전신상태, 체중 감소의 유무, 원발병소의 위치, 병리조직학적 분류, 림프절 병기 등은 생존율에 영향을 주지 않았다. 결론 : III기 비소세포성 폐암 환자에서 전통적인 방사선치료로는 장기 생존을 기대하기 어려우며 항암화학요법, 수술을 병합하는 다원적 치료 또는 변형분할조사 등의 보다 적극적인 치료가 필요할 것으로 생각된다.

Purpose : To evaluate the survival and prognostic factors in patients with stage III non-small cell lung cancer treated with curative radiotherapy alone or combined with chemotherapy Materials and Methods : A retrospective analysis was undertaken of 35 patients who had locally advanced non-small-cell lung cancer and treated with curative radiotherapy in Department of Therapeutic Radiology, Kangdong Sacred Heart Hospital, from January 1991 through December 1993. According to AJCC staging, 15 patients were stage IIIA, and 20 were stage IIIB. Radiotherapy was delivered with 1 8-2 Gy per fraction/day. 5 days per week using 6 MV X-ray, to a total dose ranging from 48.8 Gy to 66.6 Gy (median, 61.2 Gy) in 4 to 9 weeks. Ten patients received neoadjuvant or concurrent chemotherapy with FIP (5-FU, ifosfamide, and cisplatin) or FP (5-FU and cisplatin) Results : For all Patients, median survival was 6 months. 1-year and 2-year survival rates were 23.3% and 6.7%, respectively The median survival was 8 months in stage IIIA and 5.5 months in stage IIIB. In patients treated with radiation therapy alone, median survival was 5 months and 1-year survival rate was 9%. In patients who received chemotherapy, median survival was 11 months and 1-year survival rate was 60%. The difference of survival between these two groups was statistically significant (p=0.03). Total radiation dose, degree of response, and Post-treatment ECOG score were also significantly associated with survival. But it was not affected by age, sex, pretreatment ECOG score, presence or absence of weight loss, tumor location. pathologic type, N stage, and degree of response to treatment. Conclusion : Conventional radiotherapy alone is unlikely to achieve long term survival in patients with stage III NSCLC. Radiotherapy with altered fractionation schedule or multimodality treatment combined with surgery and/or chemotherapy should be considered if feasible.
