초록

목 적: 한국인 후두암 환자의 방사선치료 과정 및 방법(patterns of care)을 조사하고 병원간의 차이가 있는지를 알아보고자 하였다. 대상 및 방법: 전국의 23개 병원에서 1998년 1월부터 1999년 12월까지 2년간 후두암으로 방사선치료를 받은 환자237명(성문암, 144명; 성문상부암, 93명)을 후향적으로 분석하였다. 환자 및 종양 특성, 진단방법, 치료방법의 선택, 방사선치료의 내용, 부작용 등에 대하여 조사하였으며, 방사선치료의 내용에 관해서는 1998년도 연간 신환 발생수를 기준으로 참여병원을 A군(900명 이상), B군(400명 이상, 900명 미만) 및 C군(400명 미만)으로 나누어 차이가 있는지를 비교하였다. 결 과: 환자의 연령분포는 25~88세(중앙값, 62세)였고 남자가 216명(91.1%)이었다. 임상적 병기는 성문암의 경우 I기 61.8%, II기 21.5%, III기 4.2%, IVa기 11.1%, IVb기 1.4%, 성문상부암은 I기 4.3%, II기 19.4%, III기 28.0%, IVa기 43.0%, IVb기 5.4%로 나타났다. 병기에 따른 치료방법의 선택, 방사선치료범위, 원발부위 방사선량에 있어서 병원군 간의 차이는 없었다. 모의치료방법에서 선량계산방법, 방사선에너지, 조사면배열, 고정기구사용여부에서 병원군간 통계적인 차이가 있었다. 결 론: 우리나라 후두암 환자의 방사선치료는 모의치료방법에서 병원군 간에 약간의 차이는 있으나 비교적 일정하게 시행하고 있음을 알 수 있었고 이 연구 결과는 향후 방사선치료 표준화의 기본자료로 활용될 수 있을 것으로 생각된다.

Purpose: To investigate the care patterns for radiation therapy and to determine inter-hospital differences for patients with laryngeal carcinoma in Korea. Materials and Methods: A total of 237 cases of laryngeal carcinoma (glottis, 144; supraglottis, 93) assembled from 23 hospitals, who underwent irradiation in the year of 1998 and 1999, were retrospectively analyzed to investigate inter-hospital differences with respect to radiotherapy treatment. We grouped the 23 hospitals based on the number of new patients annually irradiated in 1998; and designated them as group A (${\geq}$900 patients), group B (${\geq}$400 patients and <900 patients), and group C (<400 patients). Results: The median age of the 237 patients was 62 years (range, 25 to 88 years), of which 216 were male and 21 were female. The clinical stages were distributed as follows: for glottis cancer, I; 61.8%, II; 21.5%, III; 4.2%, IVa; 11.1%, IVb; 1.4%, and in supraglottic cancer, I; 4.3%, II; 19.4%, III; 28.0%, IVa; 43.0%, IVb; 5.4%, respectively. Some differences were observed among the 3 groups with respect to the dose calculation method, radiation energy, field arrangement, and use of an immobilization device. No significant difference among 3 hospital groups was observed with respect to treatment modality, irradiation volume, and median total dose delivered to the primary site. Conclusion: This study revealed that radiotherapy process and patterns of care are relatively uniform in laryngeal cancer patients in Korean hospitals, and we hope this nationwide data can be used as a basis for the standardization of radiotherapy for the treatment of laryngeal cancer.
