Specifically, colorectal cancer in men is one of the most sharply increasing malignancies. The objective of this study was to assess the direct costs for colorectal cancer patients and to identify the factors that influence cancer costs. Methods: The direct costs of colorectal cancer were examined with a prospective group study at a hospital. The direct costs were assessed every 3 months over a 24-month period through patient interviews, medical records, and claims data. We identified the major factors associated with the cost of colorectal cancer by using a general linear model for the log-transformed data. Results: The group was comprised of 100 patients with colon cancer and 120 patients with rectal cancer. The average costs per patient during the first and the second years after diagnosis were ₩16,280,000 and ₩5,786,000, respectively. Medical costs accounted for about 68% (₩11,090,000) of the first year’s total cost and about 62% (₩3,602,000) of the second year’s total cost. National Health Insurance (NHI) paid approximately 50% of the total medical cost. The total cost of colorectal cancer was clearly associated with the stage of the disease at first diagnosis, the cancer site, therapeutic modalities, and recurrence. Conclusions: These results indicate that colorectal cancer has a heavy financial impact on cancer patients. The total cost of colorectal cancer is clearly associated with the stage of the disease at first diagnosis. Increased efforts in terms of prevention and early detection may assist in reducing the costs.

목적: 암 발생과 사망이 증가하고 있으며, 특히 남성에서 대장암 발생이 급격하게 증가하고 있다. 본 연구는 대장암 환자가 부담하는 직접비용을 추정하고, 이에 영향을 미치는 요인을 분석하였다. 방법: 일개 병원 대장암센터에 내원하여 대장암으로 치료받은 220명을 2년간 추적조사 하였다. 직접비용은 3개월마다 환자와의 인터뷰, 의료비 청구자료, 의무기록조사로 추계하였다. 로그치환된 선형회귀분석으로 직접비용에 영향을 미치는 요인을 파악하였다. 결과: 220명의 대장암 환자 중 100명은 결장암, 120명은 직장암이었다. 대장암 환자의 진단후 1년간 지출한 직접비용은 16,280,000원이었으며, 2년째 비용은 5,786,000원이었다. 이중 의료비가 62∼68%를 차지하였으며, 의료비 중 보험자 부담금은 50%였다. 환자의 진단 당시 병기, 위치, 치료유형, 재발 여부가 직접비용에 통계적으로 유의하게 영향을 미쳤다. 결론: 대장암 환자의 진단 후 1년간 직접비용은 16,280,000원으로 환자의 경제적 부담이 큰 것으로 조사되었다. 그러나 조기 대장암은 진행암에 비해 2배 이상 직접비용이 감소하였다.
