Lymphangioleiomyomatosis (LAM) is a rare disease in women of childbearing ages that eventually leads to respiratory failure. Lung transplantation is the only conclusive therapeutic modality in end-stage LAM. While single-lung transplantation is the preferred operation, the graft failure or recurrence of LAM was reported. We performed a single lung transplantation on a 36-year-old woman suffering from respiratory failure due to lymphangioleiomyomatosis. After a 1-year follow up, the patient was readmitted because of graft failure with collapsed transplanted lung. The lung volume reduction surgery (LVRS), tracheostomy and ventilator care were performed. However, neither the medical nor surgical treatment had any effect. Subsequently, we performed a contralateral single lung re-transplantation and had a good postoperative results.

Pulmonary lymphangioleiomyomatosis is a chronic destruct8ive disease of the lung affecting women of childbearing ages which eventually leads to respiratory failure. Lung transplantation is the only conclusive therapeutic measure because this disease responds poorly to other therapies, To date only a few reports in the literature describes the clinical experience of the bilateral sequential lung transplantation of this rare condition. We performed a bilateral sequential lung transplantation on a 32-year-old woman suffering from lymphangioleiomyo-matosisw. The heart-lung block was harvested from a 51-year-old donor. We transplanted the left lung first through the clam-shell incision. As the hemodynamics deteriorated suddenly during the dissection of the right lung the right lung was transplanted under the cardio-pulmonary bypass. Although the patient's lung function was initially satisfactory the patient died of sepsis and subsequent cardiogenic shock at the postoperative 18th day. Autopsy findings showed infection of Candida albicans on the pericardium and the left lung which had been initiated possibly from the left bronchial anastomosis site,. Through detailed review of the clinical course we concluded that lung transplantation could have been performed safely on this disease provided that early diagnosis and proper management or the oppor-tunistic infection have been carried out.

Diagnostic procedures in pregnant wowen is limited and is usually delayed, especially so if she is on mechanical ventilation. A 28-year-old pregnant woman with severe dyspnea was referred to our hospital under the impression of miliary tuberculosis. The respiratory failure was so severe that patient had to be managed with mechanical ventilator under clinical impression of overwhelming pneumonia or pulmonary tuberculosis. But the patient's conditions deteriorated. Bronchoscopy and blind transbronchial lung biopsy performed to determine the nature of the etiology, and to our surprise, revealed squamous cell carcinoma of the lung.

Lung transplantation is the choice of treatment for selected patients with end-stage pulmonary disease. However, retransplantation of the lung due to primary graft failure carries a high risk of morbidity and mortality. This is a case of a 52 year old male with emphysema who continuously needed a ventilator care and a tracheostomy. He underwent a left single lung transplantation but were not able to wean from the ventilator due to primary graft failure, and therefore we decided to do a retransplantation. Bilateral sequential single lung transplantation was performed under the cardiopulmonary bypass. The patient recovered quite well and was discharged and fully active with his work. Retransplantation although it carries a high risk, is a very effective treatment in patients with primary graft failure.

From Feb.1985 to Feb.1988,76 patients with squamous cell carcinoma of the lung treated at the Department of Therapeutic Radiology in Kyungpook National University Hospital were available for the analysis of this study. All patients received radiation of 4000cGy-6600cGy with curative aim. The overall rate of complete response was 25.0% and partial response was 452.6% The complete and partial regression of tumor was 14.3% in patients treated with dose below 5000cGy and 84.1% in the group treated with dose above 5000cGy (p<0.01). The complete response was seen only in the group of patients received radiation at least 6000cGy. The patterns of failure were as follows. The rate of initial intrathoracic recurrence was 52.6% in patients with complete response. The overall rate of failure was 68.8%. Distant metastasis was found in 47.4% of patients. Bone, contralateral lung, and brain were common metastatic sites in decreasing order All of the distant metastases and 80% of local recurrences were found within the first year after treatment.

Purpose: This study aimed to identify the feasibility of the maximum standardized uptake value (SUVmax) on baseline 18F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) as a predictive factor for prognosis in early stage primary lung cancer treated with stereotactic body radiotherapy (SBRT). Materials and Methods: Twenty-seven T1-3N0M0 primary lung cancer patients treated with curative SBRT between 2010 and 2018 were retrospectively evaluated. Four patients (14.8%) treated with SBRT to address residual tumor after wedge resection and one patient (3.7%) with local recurrence after resection were included. The SUVmax at baseline PET/CT was assessed to determine its relationship with prognosis after SBRT. Patients were divided into two groups based on maximum SUVmax on pre-treatment FDG PET/CT, estimated by receiver operating characteristic curve. Results: The median follow-up period was 17.7 months (range, 2.3 to 60.0 months). The actuarial 2-year local control, progression-free survival (PFS), and overall survival were 80.4%, 66.0%, and 78.2%, respectively. With regard to failure patterns, 5 patients exhibited local failure (in-field failure, 18.5%), 1 (3.7%) experienced regional nodal relapse, and other 2 (7.4%) developed distant failure. SUVmax was significantly correlated with progression (p = 0.08, optimal cut-off point SUVmax > 5.1). PFS was significantly influenced by pretreatment SUVmax (SUVmax > 5.1 vs. SUVmax ≤ 5.1; p = 0.012) and T stage (T1 vs. T2-3; p = 0.012). Conclusion: SUVmax at pre-treatment FDG PET/CT demonstrated a predictive value for PFS after SBRT for lung cancer.

A total of forty patients with resected N2 stage non-small cell lung cancer treated with postoperative adjuvant radiation therapy between Jan. 1975 and Dec. 1990 at the Department of Radiation Oncology, Yonsei University College of Medicine, Yonsei Cancer Center were retrospectively analysed to evaluate whether postoperative radiation therapy improves survival. Patterns of failure and prognostic factors affecting survival were also analysed. The 5 year overall and disease free survival rate were $26.3\%,\;27.3\%$ and median survival 23.5 months. The 5 year survival rates by T-stage were $T1\;66.7\%,\;T2\;25.6\%\;and\;T3\;12.5\%.$ Loco-regional failure rate was $14.3\%$ and distant metastasis rate was $42.9\%$ and both $2.9\%.$ Statistically significant factor affecting distant failure rate was number of postitive lymph nodes(>=4). This retrospective study suggests that postoperative radiation therapy in resected N2 stage non-small cell lung cancer can reduce loco-regional recurrence and may improve survival rate as compared with other studies which were treated by surgery alone. Further study of systemic control is also needed due to high rate of distant metastasis.

A total of eighty one patients with resected stage II and IIIA non-small cell lung cancer treated with postoperative adjuvant radiation therapy between Jan. 1971 and Dec. 1990 were retrospectively analysed to evaluate whether postoperative radiation therapy improves survival. Patterns of failure and prognostic factors were also analysed. The 5 year overall and disease free survival rate were 40.5%, 43.4% and median survival 30 months. The 5 year actuarial survival rates by stage II and IIIA were 53.9% and 36.2%. Loco-regional failure rate was 14.7% and distant metastasis rate was 33.3% and both 4%. Statistically significant prognostic factor affecting survival was presence of mediastinal lymph node metastasis[N2]. This retrospective study suggests that postoperative radiation therapy in resected stage II and IIIA non-small cell lung cancer can reduce loco-regional recurrence and may improve survival rate as compared with other studies which were treated by surgery alone.

Congenital cystic disease of the lung is very rare and controversial disease. But in general is regarded as developmental anomaly. Occasionally failure of the primitive lung bud to develop combined with cardiac anomaly had been reported but it was very rare. Recently a case of cystic lung disease combined with pulmonic valvular stenosis was seen in this clinic with clinical pictures of nonspecific respiratory infection and X-ray finding very similar to that of far advanced pulmonary tuberculosis, destroyed left lung. This case was treated by closed pulmonic valvulotomy and left side pneumonectomy successfully.

Chronic eosinophilic pneumonia is an idiopathic condition characterized by chronic infiltration of the lung with eosinophils, weight loss, dyspnea, and pulmonary infiltration. Recently, we have experienced one case of chronic eosinophilic pneumonia presenting as the acute respiratory failure. A 34-year-old man was admitted to the hospital with one month's history of coughing, dyspnea, mucoid sputum, weight loss and one day's history of subcutaneous emphysema. The radiographic lung lesion and dyspnea rapidly progressed to a critical condition of acute respiratory failure. The combination of blood eosinophilia, lung infiltration on the chest x-ray, sign of acute rapiratory failure, rapid response to steroid therapy, and the finding of the transbronchial lung biopsy permit the diagnosis of chronic eosinophilic pneumonia.
