Lung cancer is one of the most disastrous of all the current cancers in Korea. In 1990 it was projected that there would be 5, 500 new lung cancer patients in Korea and that 5, 000 would die of their disease. This is a mortality rate of 91 percent. We reviewed the surgically treated 153 bronchogenic cancer patients from January 1987 to December 1991 in St. Mary`s Hospital of Catholic University Medical College. There were 121 men and 32 women ranging in age from 18 to 83 years, with a mean of 56 years. Of the 153 patients, resection was possible in 138 patients and the resectability was 90.1 percent. Squamous cell carcinoma was present in 48 percent of patients, adenocarcinoma in 29 percent, adenosquamous carcinoma in 7 percent, large cell carcinoma in 6 percent, salivary gland tumor in 5 percent, and small cell carcinoma and carcinoid in 3 percent respectively. Postoperative cancer staging was grouped stage I 33 percent, stage II 21 percent, stage IIIa 35 percent, and stage IIIb 10 percent. Lobectomy was performed in 70 percent, pneumonectomy in 17 percent, and segmentectomy in 14 percent. Three and 5-year postoperative survival in resectable 138 patients were 47 and 29 percent respectively.

Purpose: Generally, the treatment of ankle trimalleolar open fractures is divided into two stages: external fixation and debridement; and secondary internal fixation. On the other hand, this two-stage operation takes considerable treatment time and is challenging in procedures requiring reduction. The purpose of this study was to evaluate the radiologic and clinical results of an immediate one-stage internal fixation operation considering the wound conditions to overcome two stage operation disadvantages. Materials and Methods: From September 2009 to January 2018, 24 cases of ankle trimalleolar open fractures, who underwent immediate internal fixation and were followed up for at least one year, were studied retrospectively. The open wound was divided into the Gustilo-Anderson classification. Open reduction and internal fixation were performed on every medial and lateral malleolar fracture. On the other hand, with posterior malleolar fractures, surgical or conservative treatment was performed depending on the fragment size. The radiologic outcome was evaluated using the Burwell and Charnley criteria and American Orthopaedic Foot and Ankle Society (AOFAS) scores, and complications, such as infection and posttraumatic arthritis, were used for the clinical evaluation. Results: The wound was classified into eight cases (33.3%) of type I, 11 cases (45.8%) of type II, and five cases (20.8%) of type IIIa. The degree of reduction was anatomical, fair, and poor in 16 cases (66.7%), six cases (25.0%), and two cases (8.3%), respectively. The mean AOFAS score was 79 points, and there were complications, such as infection in three cases (12.5%) and post-traumatic arthritis in two cases (8.3%). Conclusion: Satisfactory results were obtained through immediate surgical treatment in ankle trimalleolar open fractures of types I, II, and IIIa.

The lung cancer in patients under 40 years old is rare and reported to be more rapidly fatal than in older persons. We reviewed the records of 18 cases who younger than 40 years with histologically proven lung cancer between 1959 and 1992 at department of Thoracic Surgery in National Medical Center. There were 12 male and 6 female patients. Two male and all female patients had never smoked. The 17 cases had respiratory symptoms for a mean duration of 3 months. The squamous carcinoma was found in 7 cases[38.9%], small cell carcinoma in 4 cases[22.2%], mixed cell carcinoma in 4 cases[22.2%], adenocarcinoma in 2 cases[11.1%] and bronchoalveolar cell carcinoma in 1 case. Among the 6 resected tumors, one case was stage I, two cases were stage II and three cases were stage IIIa. The operation was considered complete and curative in 6 patients and noncurative in 6 pations because of an exploratory thoracotomy. We conclude that lung cancer in young persons is virulent and that diagnosis is frequently delayed.

연구배경 : 기관지 폐포암의 발생빈도가 타 원발성 폐암의 발생속도보다 빠르게 증가하고 있는 추세이고 조기진단 및 이에 따른 적절한 수술적 치료가 이루어진 경우 뛰어난 예후를 기대할 수 있다. 그러나 국내에 기관지 폐포암에 대한 보고가 적고 무엇보다도 이 암의 임상양상이나 방사선학적 소견이 우리 주변의 흔한 다른 폐질환과 유사한 양상을 나타내 감별진단이 어려우므로 적절한 수술시기를 놓칠 수 있어 이에 저자들은 기관지 폐포암 환자의 임상적 양상, 방사선학적 소견, 치료 및 그에 따른 예후등을 분석해 보고자 하였다. 방법 : 5년간 발생한 기관지 폐포암 환자 24예를 대상으로 환자의 성별, 연령분포, 주 증세 발현시기, 흡연력, 선행 폐질환의 유무 등을 조사하였고 내원당시 환자의 자각증상 및 이학적 소견을 분석하고 치료를 받은 환자에 있어 예후를 조사하였으며 각각의 방사선학적 소견에 따른 예후를 후향적으로 분석해 보았다. 결과: 1) 5년간 진단받은 기관지 24예는 폐포함 24예는 동 기간 발생한 원발성 폐암의 1.3%였다. 2) 대상 환자의 남녀비는 1:1.4이였고 50대가 13예(54.1%)로 빈도가 가장 높았다. 대상 환자중 1~3개월전 주 증세가 발현한 경우가 8예(33.3%)로 가장 많았고 주 증세로 기침이 15예(65%), 객담 및 흉통이 각각 7예(29.2%)이였다. 3) 방사선학적소견상 고립성 결절형이 13예(54.2%)로 가장 많은 빈도를 보였고 다발성 결절형 6예(25%), 침윤성 4예(16.7%), 공동을 동반한 결절형 1예(4%)의 순이였다. 4) 기관지 폐포암의 진단은 미세침 폐생검을 통해 14예(58.3%), 객담 세포검사를 통해 11예(45.8%)에서 확진을 얻었으며 경기관지 폐생검으로 7예(29.2%), 개흉 폐생검으로 2예에서 확진을 얻었다. 5) 진단시 환자들의 병기는 stage IIIb 이상이 14예(58.3%)로 수술적 치료를 할 수 없는 경우가 대부분이었다. 6) 대상 환자중 stage IIIa이하인 7예와 stage IV 1예, 총 8예에서 폐절제술, 폐엽절제술, 설절제술등의 수술적 치료를 시행하였다. 이 중 타 질환으로 사망한 1예를 제외하고 4예에서 최고 61개월간 재발의 증거 없이 생존하고 있으며 4예 모두 고립성 결절형이거나 국소적인 병변을 가진 stage I, II의 환자들이였다. 방사선학적 소견에 따른 예후를 비교해 보았을 때 고립성 결절형인 경우 6개월, 12개월 누적 생존율이 각각 66.6%, 58.3%로 66.6%, 1.67%의 다발성 결정형인 경우 보다 뛰어난 예후를 보임을 알 수 있었다. 결론 : 이상의 결과로 미루어 보아 기관지 폐포암의 치료를 위해서는 임상의사의 적극적인 노력과 환자의 협조로 기관지 폐포암을 조기발견하여 가능한한 초기에 수술을 시행하여야 한다고 사료되며 특히 병변이 고립성 결절형이거나 국소적일 경우 폐절제술 및 폐엽절제술 등의 수술적 치료를 시행하여야 좋은 예후를 기대할 수 있으리라 사료된다.

Background: To investigate the related risk factors of postoperative nosocomial pneumonia (POP) in patients withI-IIIa lung cancer. Methods: Medical records of 511 patients who underwent resection for lung cancer between January 2012 to December 2012 were retrospectively reviewed. Risk factors of postoperative pneumonia were identified and evaluated by univariate and multivariate analyses. Results: The incidence of postoperative pneumonia in these lung cancer patients was 2.9% (15 cases). Compared with 496 patients who had no pneumonia infection after operation, older age (>60), histopathological type of squamous cell carcinoma and longer surgery time (>3h) were significant risk factors by univariate analysis. Other potential risk factors such as alcohol consumption, history of smoking, hypersensitivity, hypertension, diabetes mellitus and so on were not showed such significance in this study. Further, the multivariate analysis revealed that old age (>60 years) (OR 5.813, p=0.018) and histopathological type of squamous cell carcinoma (OR 5.831, p<0.001) were also statistically significant independent risk factors for postoperative pneumonia. Conclusions: This study demonstrated that being old aged (>60 years) and having squamous cell carcinoma histopathological type might be important factors in determining the risk of postoperative pneumonia in lung cancer patients after surgery.

We present a case of an unusual infectious complication of a ruptured mediastinal abscess after endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), which led to malignant pleural effusion in a patient with stage IIIA non-small-cell lung cancer. EBUS-TBNA was performed in a 48-year-old previously healthy male, and a mediastinal abscess developed at 4 days post-procedure. Video-assisted thoracoscopic surgery was performed for debridement and drainage, and the intraoperative findings revealed a large volume pleural effusion that was not detected on the initial radiographic evaluation. Malignant cells were unexpectedly detected in the aspirated pleural fluid, which was possibly due to increased pleural permeability and transport of malignant cells originating in a ruptured subcarinal lymph node from the mediastinum to the pleural space. Hence, the patient was confirmed to have squamous cell lung carcinoma with malignant pleural effusion and his TNM staging was changed from stage IIIA to IV.
