Abstract

Background: It is known that long-term survival rate in patients underwent bronchial sleeve lobectomy for primary lung cancer is at least equal to that in patients underwent pneumonectomy, and bronchial sleeve lobectomy is performed in patients with suitable tumor location even in patients have adequate pulmonary function. Sleeve pneumonectomy is performed when carina was invaded by tumor or tumor location was near to the carina. We performed this study to know our results of sleeve resection for primary lung cancer. Material and Method: We analyzed retrospectively the medical records of 45 patients who underwent sleeve lobectomy or sleeve pneumonectomy for primary lung cancer by one thoracic surgeon from May 1990 to July 2003 in Department of Thoracic & Cardiovascular Surgery, College of Medicine, Kyung Hee University. Follow-up loss was absent and last follow-up was performed in April 5, 2005. Kaplan-Meyer method and log-lank test were used to know long-term survival rate and p-value. Result: Mean age was 60 years old and male to female ratio 41:1. Histologic types were squamous cell carcinoma were 39, adenocarcinoma were 4, and others were 2 patients. Pathologic stages were I 14, II 14, and III 17 patients. Nodal stages were N0 23, N1 13, and N2 9 patients. Types of operation were sleeve lobectomy 40 and sleeve pneumonectomy 5 patients. Operative mortality was 3 patients and its cause was respiratory complications. Early complications were pneumonia 4, atelectasis 8, air leakage more than 7 days 6, and atrial fibrillation 4 patients. In 19 patients tumor was recurred. Local recurrence was 10 and systemic metastasis was 9 patients. Overall 5, 10-year survival rate were 54.2%, 42.5%. The 5, 10-year survival rates according to the pathologic stage were 83.9%, 67.1% in stage I, 55%, 47.1% in II, 33.3%, 25% in III, and significance difference was present between stage I and III. The 5, 10-year survival rate according to the lymph node involvement were 63.9%, 54.6% in N0, 53,8%, 46.5% in N1, 28.5%, 14.2% in N2, and significance difference was present between N0 and N2. Conclusion: Because bronchial sleeve lobectomy for primary lung cancer could be performed safely and shows acceptable long-term survival rate, it could be considered primary in case of suitable tumor location if complete resection is possible. Although sleeve pneumonectomy for primary lung cancer shows somewhat high operative mortality rate, it could be considered in view of curative treatment.

배경: 원발성 폐암에 대한 기관지 소매 폐엽절제술 후의 장기 생존율은 전폐절제술 후의 장기 생존율과 비교해 최소한 동일하다고 알려져 있고, 충분한 폐기능을 가진 환자에서도 종양의 위치가 적절하면 기관지 소매 폐엽절제술이 시행되고 있다. 소매 전폐절제술은 종양이 기관분기부를 침범하거나 기관분기부에 가깝게 위치한 경우에 시행된다. 저자들은 원발성 폐암에 대해 본원에서 시행한 기관지 소매 절제술의 성적을 알아보고자 하였다. 대상 및 방법: 1990년 5월부터 2003년 7월까지 경희대학교 흉부외과학교실에서 한 명의 흥부외과 의사에 의해 원발성 폐암으로 소매 폐엽절제술 또는 소매 전페절제술을 시행 받은 45명의 환자를 후향적으로 분석하였다. 최종 추적일은 2005년 4월 5일이었으며 모든 환자에서 추적 가능하였다. 생존율은 Kaplan-Meyer방법으로, 통계적 유의성은 log-rank test로 검정하였다. 결과: 평균 나이는 60세였고, 남녀 비는 44:1이었다. 조직학적으로 편평상피세포암이 39명, 선암이 4명, 기타 2명이었고, 수술은 폐엽절제술이 40명, 소매 전폐절제술이 5명이었다. 병기 I이 14명, II가 14명, III가 17명이었으며, N0 23명, N1 13명, N2 9명이었다. 3명의 수술 사망자가 있었으며, 모두 호흡기계 관련 합병증으로 사망하였다. 초기 합병증은 폐렴 4명, 무기폐 8명, 7일 이상의 공기 누출 6명, 심방 세동 4명이었다. 19명에서 종양이 재발하였다. 국소 재발이 10명이었고, 원격 전이는 9명이었다. 전체 환자의 5년, 10년 생존율은 54.2%, 42.5%였다. 병기에 따른 5년, 10년 생존율은 병기 I 83.9%, 67.1%, II 55%, 47.1%, III 33.3%, 25%였으며, 병기 I과 III간에만 통계적 유의성이 있었다. 림프절 침범에 따른 5년, 10년 생존율은 N0 63.9%, 54.6%, N1 53.8%, 46.5%, N2 28.5%, 14.2%였으며, N0와 N2간에만 통계적 유의성이 있었다. 결론: 원발성 폐암에 대한 소매 폐엽절제술은 비교적 안전하게 시행될 수 있고 장기 생존율이 양호하므로 종양의 위치가 수술에 적절하고 완전 절제가 가능한 경우 우선적으로 고려할 수 있는 수술 방법이다. 원발성 폐암에 대한 소매 전폐절제술은 수술 사망률이 다소 높지만 종양의 근치적 측면에서 고려할 수 있는 수술 방법이다.
