  • 52세 여자 환자가 호흡곤란을 주소로 내원하였다. 환자는 2개월 전에 침습성 흉선종으로 광범위 흉선절제술을 받았다. 전산화단층촬영에서는 양측 폐에 수많은 소결절들이 발견되었다. 급성 호흡곤란 증후군이 악화되어 혈관외과의는 정맥-정맥 체외막산소공급(extracorporeal membrane oxygenation; 이하 ECMO)을 계획하였다. 왼쪽 대퇴동맥을 통해 경피적 삽관술을 시행하는 도중에 혈관외과의는 혈관 손상을 의심하였고 환자의 활력 징후가 불안정해졌다. 8일 전에 촬영한 복부 컴퓨터단층촬영에서 May-Thurner 증후군이 있었고, 이후 시행한 혈관조영술에서 좌측 총장골정맥의 파열이 발견되어 stent-graft를 삽입하여 출혈을 멈추었다. 8일 전 시행된 복부 전산화단층촬영을 확인해 보니 May-Thurner 증후군이 있었다. 이에 May-Thurner 증후군 환자에서 ECMO 삽관으로 인한 혈관 손상이 발생하여 스텐트 삽입술을 시행하였던 드문 증례를 보고하고자 한다.

  • 목 적: 흉선종환자에서 방사선치료 효과를 평가하고 생존율에 영향을 미치는 예후인자를 파악하기 위하여 후향적 분석을 시행하였다. 대상 및 방법: 2002년 3월부터 2008년 1월까지 본원에서 흉선종으로 진단 받고 방사선치료를 시행 받은 21명의 환자를 분석하였다. 대상환자의 추적관찰 기간은 3~89개월(중앙값, 37개월)이었다. 남녀 구성비는 4:3이었고 연령분포는 24~77세(중앙값, 57세)이었다. Masaoka병기는 II기 10명(47.6%), III기 7명(33.3%), IVa기 4명(19.1%)이었다. 전체 21명 중 15명(완전절제[흉선절제술], 14명; 불완전절제, 1명)에서 수술이 시행되었고, 시험적 개흉술(exploratory thoracotomy), 경부림프절 생검 등을 포함한 조직검사만 시행한 경우는 6명(28.6%)이었다. 병리학적으로 WHO 세포형 A 1명(4.8%), B1-3 10명(47.6%), C 10명(47.6%)이었다. 방사선치료는 3차원입체조형기법으로 시행하였고 총 방사선선량은 52~70.2 Gy (중앙값, 54 Gy)이었다. 성별, 연령, 종양의 크기, 병리학적 분류, Masaoka 병기, 수술시행 여부, 근무력증 유무 및 방사선량 등에 따른 전체 및 무진행생존율의 차이를 분석하였다. 결 과: 전체 환자에서 3년 생존율은 80.7%이었고 3년 무진행생존율은 78.2%이었다. WHO 세포형 C 10명에서 완전절제를 시행한 4명 중 3명(75%)이 생존하였고, 조직검사만 시행한 6명 중 3명(50%)이 생존하였다. 수술을 시행받은 15명 중 방사선조사 범위 내에서의 재발은 없었다. 4명(19.1%)에서 원격전이가 확인되었다. 조직검사만 시행받은 6명의 치료반응은 부분관해 4명(66.6%), 불변 1명(16.7%) 그리고 진행 1명(16.7%)이었다. 치료 후 방사선폐렴이 Radiation Therapy Oncology Group (RTOG) grade 1이 1명(4.8%), grade 2가 2명(9.5%), grade 3과 grade 4가 각각 1명(4.8%) 있었다. 단변량 분석상 생존율에 유의한 예후인자는 연령(60세 이상, 58.3%; 60세 미만, 100%; p=0.0194), 병리학적 분류(WHO 세포형 A-B3, 100%; C, 58.3%; p=0.0194), 수술시행여부(시행, 93.3%; 미시행, 50%; p=0.0096)이었다. 결 론: 수술 후 보조적으로 방사선치료를 시행 받은 15명 모두 방사선치료 조사야 내 재발이 없었고 WHO 세포형 C에서 방사선치료 전 수술이 시행된 경우 조직검사만 시행된 경우보다 좋은 성적을 보였다. 이에 저자들은 흉선종 환자들을 대상으로 한 방사선치료 경험을 보고하는 바이다.

  • This is the result of the annual statistic analysis of thoracic and cardiovascular surgical cases in 1992 Korea. Overall 17, 520 cases of surgery [11, 732 cases of thoracic surgery by 54 institutes / 5, 788 cases of cardiovascular surgery by 48 institutes] were done. 1. Tumor [N=2, 532] : Lung was the most frequently involved organ by tumor [54.9%],and the remainders were mediastinum [16.2%] / esophagus [14.8%] / chest wall [11.7%] / tracheobronchus [1.3%] / pleura [1.1%] in order. Of 1, 082 cases of primary lung cancer surgery,the frequency of cell type was squamous [62.6%] / adeno [21.6%] / small cell [7.1%] / large cell [2.7%]. Of 411 cases of mediastinal tumor surgery,the frequency of cell type was neurogenic [28.8%] / thymoma [27.6%] / teratoma [17.7%] / congenital cystic [17.2%].

  • Background: Thymic epithelial tumors (TETs) are rare, and information regarding their surgical outcomes and prognostic factors has rapidly changed in the past few decades. We analyzed surgical treatment practices for TETs and outcomes in terms of overall survival (OS) and freedom from recurrence (FFR) during a 13-year period in Korea. Methods: In total, 1,298 patients with surgically resected TETs between 2000 and 2013 were enrolled retrospectively. OS and FFR were calculated using the Kaplan-Meier method and evaluated with the log-rank test. Prognostic factors for OS and FFR were analyzed with multivariable Cox regression. Results: A total of 1,098 patients were diagnosed with thymoma, and 200 patients were diagnosed with thymic carcinoma. Over the study period, the total number of patients with surgically treated TETs and the proportion of patients who underwent minimally invasive thymic surgery (MITS) increased annually. The 5-year and 10-year survival rates of surgically treated TETs were 91.0% and 82.1%, respectively. The 5-year and 10-year recurrence rates were 86.3% and 80.0%, respectively. The outcomes of surgically treated TETs improved over time. Multivariable Cox hazards analysis for OS, age, tumor size, and Masaoka-Koga stage were independent predictors of prognosis. The World Health Organization classification and tumor-node-metastasis (TNM) staging were also related to the prognosis of TETs. Conclusion: Surgical treatment of TETs achieved a good prognosis with a recent increase in MITS. The M-K stage was the most important prognostic factor for OS and FFR. The new TNM stage could also be an effective predictor of the outcomes of TETs.
