초록

배경: 여러 가지 고형암으로부터 전이된 폐암 환자에 있어서 수술적 절제는 중요한 치료 방법 중 하나다. 이를 토대로 본원에서 1996년부터 2005년까지 37명의 환자에서 시행한 전이성 폐암의 수술적치료에 대해 분석해 보고자 한다. 대상 및 방법: 환자의 입원기록과 수술기록, 병리기록지 등을 통하여 나이, 성별, 무병생존기간, 수술 방법, 폐 전이 병소 개수, 림프절 전이 여부 등을 조사하였다. 생존곡선과 생존율간의 비교는 각각 Kaplan-Meier life table과 log-rank test를 이용하였다. 결과: 37명의 환자 중 34명에서 완전 절제가 가능하였다. 원발 종양은 암종이 25명, 육종이 10명, 다른 종류가 2명이었으며 폐 전이 개수는 1개가 25명, 2개 이상이 12명이었다. 완전 절제가 가능했던 환자 군에서 수술후 3년 생존율은 50.5%, 5년 생존율은 35.9%으로 나타났다. 원발 종양의 종류에 따라 생존율을 비교하였을 때 암종에서의 3년 생존율은 64.5%, 5년 생존율은 45.6%로 나타났으나 육종에서의 3년 생존율은 17.5%로 낮게 나타났다. 반면, 수술 방법, 폐 전이 개수, 림프절 전이 여부, 추가 항암치료 여부와 암종에서 무병생존 기간 등은 생존율에 유의하게 영향을 미치지 못했다. 결론: 전이성 폐암은 완전 절제가 가능할 경우 잘 선택된 일부 환자에서 수술에 따른 사망률이나 이환율은 낮으면서도 높은 장기 생존율을 기대할 수 있는 질환이다. 전이성 폐암의 수술 후 예후인자 등에 대한 차후 장기적인 추적관찰과 무작위 전향적 비교 연구 등이 더 필요할 것으로 보인다.

Background: Surgical resection is an important modality in the treatment of pulmonary metastases from various solid tumors. We analyzed 37 patients who underwent surgical treatments of pulmonary metastases in our hospital from 1996 to 2005. Material and Method: Age, sex, disease free interval, operative procedure, the number of pulmonary metastases, and lymphatic metastasis were investigated with admission and operative records, and pathologic reports. Actuarial survival and comparisons between each survival rate were calculated according to Kaplan-Meier method and log-rank test, respectively, Result: Complete resections were carried out in 34 of 37 patients. The primary tumor was carcinoma in 25 cases, sarcoma in 10, and others in 2. The number of pulmonary metastases was 1 in 25 cases and 2 or more in 12 cases. 3-year and 5-year survival rates after complete resection were 50.5% and 35.9%, respectively. 3-year and 5-year survival rates for carcinoma were 64.5% and 45.0%, respectively, and 3-year survival rate for sarcoma was 17.5%. Otherwise, none of the operative procedures, the number of pulmonary metastases, lymphatic metastasis, adjunctive therapy and the disease free interval in the case of carcinoma significantly affected the survival rates. Conclusion: Complete resection of pulmonary metastasis in well selected patients allows high long term survival rate with low mortality and morbidity. Long-term follow up and randomized prospective studies were necessary to determine the prognostic factors of pulmonary metastases after surgical resection.
