Abstract

Background: In spite of the development of chemotherapy, prognosis of metastatic lung cancer was poor. On the other hand, surgical intervention has proven itself to bring out superior results, therefore more operations are being praticed based on this superiority against chemotherapy and other modalities on metastatic lung cancer. Material and Method : We analyzed the surgical cases performed from 1983 to 1997 on 17 cases and estimated 5 year survival rate using Kaplan-Meier method. Result: Average age was 42.8, ratio between male and female was 10:7. We had 8 single lobe resections,3 pneumonectomies,1 wedge resection,2 bilobectomy and 3 cases of lobar resection with wedge resection. 5 deaths have occured and among the 5, 3 patients were caused by recurrence of ca. The remaining 12 patients are being followed up in OPD basis among these, 3 recurrence were observed and 9 are still free of cancer. The average survival time was 40.5 months and 5 year survival rate obtained through the Kaplan-Meier method was 60.4%. Conclusion: Even though we are a bit short of cases, we recommend that a thoracic surgeon approach this disease through a surgical method as possibly as he could.

배경: 최근 항암화학요법의 발달에도 불구하고 전이성폐암에 대한 예후는 불량하다. 이에비해 전이성폐암에 대한 외과적 요법후 좋은 결과를 보이는 보고가 증가하고 있다. 그래서 전이성 폐암에 대한 치료에 도움이 되고자 본원의 경우를 관찰하였다. 대상 및 방법: 1983년부터 1997년까지 수술적 치료를 했던 17례를 분석하였고 Kaplan-Meier 방법으로 5년생존률을 구하였다. 결과: 평균연령은 42.8세였고 남녀비는 10:7이었다. 수술은 단일폐엽절제술이 8례, 전폐적출술이 3례, 부분절제술이 1례, 쌍폐엽절제술이 1례, 폐엽절제술 및 부분절제가 3례있었다. 술후 5명이 사망하였고 이중 재발로 인한 것은 3례였다. 나머지 12례의 환자들중 3명은 재발하여 현재 외래추적관찰중이며 9명은 재발없이 건강한 상태로 외래추적 관찰중에 있다. 술후 평균 생존기간은 40.5개월이었다. Kaplan-Meier 방법으로 구한 5년생존율은 60.4%였다. 결론: 앞으로 더많은 경험이 필요하지만 전이성폐암에 대해서 더 적극적인 수술적치료를 하는 것이 필요하다고 생각한다.
