Since the year 2000, lung cancer has become the leading cause of cancer death in South Korea as in many other parts of the world. The current multidisciplinary approach for lung cancer includes a wide range of modalities, not only surgery, radiotherapy, medical drug therapy but also pain control, as well as social and psychological support. Therefore, thoracic surgeons, radiologists, nuclear medicine specialists, anesthetists, psychologist, nurses and social workers as well as medical doctors care for lung cancer patients . Sharing a common treatment protocol and optimal communication are vital aspects of shared care both from a medical and cost-effectiveness point of view. We developed a shared electronic medical record (SEMR) for treating patients with lung cancer in a university hospital to facilitate the sharing protocols and communications between doctors involved in a lung cancer clinic.
연구배경 : 우심실부전 또는 쇽을 보였던 중증 폐색전증에서 혈전용해요법 혹은 항응고요법을 시행했을 때 예후의 차이에 대해 조사해 보고자 하였다. 방 법 :1995년 1월부터 2004년 12월까지 서울아산병원에 입원했던 폐색전증 환자 중에서 우심실부전 혹은 쇽이 있었던 총 60명의 환자를 대상으로 의무기록 분석을 통해서 후향적으로 조사하였다.
Background : ‘Major pulmonary thromboembolism’ is defined as right ventricular (RV) dysfunction, with or without shock, accompanied by significant morbidity and mortality. In this study, those with major pulmonary thromboembolism were divided into the shock and RV dysfunction only groups, and then investigated the mortality and complications in thrombolysis or anticoagulation, respectively. Methods : In a retrospective study, between January 1995 and December 2004, 60 eligible patients with a major pulmonary thromboembolism, admitted in Asan Medical Center, were included. Results : A total of 57 patients were treated with medical therapy. Thrombolysis was performed in 13 patients (23%) and anticoagulation in 44 (77%). There were no differences in the APACHEⅡ and SOFA scores between the two groups. 6 (46%) and 11 (25%) patients died in the thrombolysis and anticoagulation groups, respectively (p=0.176). In the 19 patients (33%) showing shock, thrombolysis was performed in 9 (47%) and anticoagulation in 10 (53%). 4 (44%) of the 9 patients treated with thrombolytic agents and 3 (30%) of the 10 treated with anticoagulants died (p=0.650). In the 38 patients (67%) showing RV dysfunction only, thrombolysis was performed in 4 (11%) and anticoagulation in 34 (89%). 2 (50%) of the 4 patients treated with thrombolytics and 8 (24%) of the 34 treated with anticoagulants died (p=0.279). Three patients (23%) who underwent thrombolysis had a major bleeding episode, compared with 2 (5%) who were treated with anticoagulants (p=0.072). Conclusion: The results of our study showed that thrombolysis did not lower mortality and tended to increase major bleeding compared with anticoagulation in both the shock and RV dysfunction only groups. Further evaluation of the efficacy and safety of thrombolytic therapy for major thromboembolism appears warranted in Korea. (Tuberc Respir Dis 2005; 59: 487-496)
연구배경 : 호흡기 바이러스 감염은 천식 및 만성폐쇄성폐질환의 악화와 관련이 있다고 알려져 있지만 국내의 자료는 충분치 않다. 방 법 : 급성 악화로 한림대학교 성심병원에 내원한 천식 환자 20명과 COPD 환자 24명을 대상으로 비강 분비물과 객담에서 PCR과 배양을 통해 호흡기 바이러스를 검출하였다. rhinovirus, coronavirus는 PCR을, influenza A, B, RSV, parainfluenza virus는 배양을 통해 바이러스를 검출하였다.
Backgrounds : The exacerbations of asthma and chronic obstructive pulmonary disease (COPD) have been suggested to be associated with respiratory tract viral infections (RTVIs). However, the rates of virus detection in previous studies have been quite variable, with lower rates for the exacerbation of COPD. Therefore, the virus detection of patients with exacerbation of asthma and COPD were investigated. Methods : 20 and 24 patients with exacerbation of asthma and COPD, respectively, were enrolled. Nasal and sputum samples were taken, and polymerase chain reaction (PCR) for rhinovirus and coronavirus and virus culture for influenza A, B, RSV and parainfluenza virus performed. Results : The mean FEV1/FVC in the exacerbation of asthma and COPD patients were 1.9/2.9 L (65.5%) and 1.1/2.6 L (42.3%), respectively. Respiratory virus was detected in 13 (65%) patients with exacerbation of asthma and rhinovirus was detected in 9. Coronavirus, influenza A, RSV and parainfluenza virus were detected in 2, 2, 1 and 1 patients with asthma. Among patients with exacerbation of COPD, a virus was detected in 14 (58.3%) patients, with rhinovirus, coronavirus and influenza A detected in 10, 3 and 4, respectively. Conclusions : This study suggested that RTVIs may have a role in the exacerbation of COPD as well as asthma. (Tuberc Respir Dis 2005; 59: 497-503)
배 경 : 폐암의 경과 중 종양에 의한 기도폐쇄로 발생하는 호흡곤란은 환자의 삶의 질을 저하시키는 중요한 요인이다. 이런 환자들에서 전기탐침과 투열 올가미를 이용하여 굴곡성 기관지경을 통해 시행한 전기 소작술의 치료효과를 조사하였다. 방 법 :기도를 침범한 종괴로 인해서 호흡곤란을 호소하는 19명의 폐암환자(편평상피암 14례, 선암 1례, 전이성 폐암 4례)를 대상으로 하였다. 평균 나이는 61±10세였으며 남자가 17명 여자가 2명이었다. 폐쇄부위는 기관이 2례, 주기관지가 17례였다. 국소마취 하에서 굴곡성 기관경을 통해 전기소작술을 총 29회 시행하였으며 소작시 30W의 전력을 사용하였다. 치료 전에 modified Borg category scale(0～10), 환기기능검사 및 기관지 내시경검사를 실시하였고 시술 후 3-4일 후에 modified Borg category scale(0～10)의 변화 및 환기기능 검사를 시행하였고, 정화 기관지경술(clean- up bronchoscopy)을 시행하여 기도폐쇄의 완화의 정도를 측정하였다.
Background : Endobronchial tumors cause life-threatening dyspnea and can lower the quality of life due to central airway obstruction. In those cases with an intraluminal tumor, various bronchoscopic techniques are available for tumor debulking. The therapeutic effect of bronchoscopic electrocautery for palliation in patients with a symptomatic tumor obstruction was studied. Method : Nineteen patients with bronchogenic carcinomas (n=15) and metastatic tumors affecting the bronchi (n=4), between March 2002 and March 2005, were enrolled in this study. Electrocautery was performed under local anesthesia using an electroprobe and diathermic snare. Using flexible bronchoscopy, a follow-up bronchoscopic examination was performed 3-4 days later. Symptom improvement was evaluated by FEV1, FVC and dyspnea score (Modified Borg Category Scale (0∼10)), both before and after the electrocautery. Results : The success rate of electrocautery on the follow up examination was 84%. Patients with endoluminal airway lesions had a mean overall decrease in the size of the obstruction to 47.8±15.7%. The mean Improvement in the dyspnea score immediately after the endobronchial tumor debulking was 2.78±1.42. The average improvements in the FEV1 and FVC after electrocautery were 0.32±0.19L and 0.5±0.22L, respectively. There were 2 cases of complications related with electrocautery (one each of pneumothorax and pneumonia). Conclusion : Electrocautery using an electroprobe and diathermic snare was an effective and safe palliative treatment for a symptomatic endoluminal airway obstruction in lung cancer.

배 경 :새로운 항암제의 사용으로 비소세포 폐암에서 1차 항암 치료의 효과는 많이 향상 되었지만 많은 환자에서 치료 중 혹은 치료 후에 폐암이 진행하거나 재발되고 있다. 최근 환자의 체력 및 영양 상태의 향상으로 폐암의 진행 및 재발 후에도 신체 수행 상태(performance status)가 양호하여 2차 항암 치료의 대상 환자가 늘어나는 추세이다. 그러나 아직까지 표준화된 2차 항암 치료가 없는 실정으로 gemcitabine과 vinorelbine의 병합 요법은 비교적 다른 기전의 독성을 보여 병합 요법으로서의 가능성을 높여 주었다. 이에 저자들은 1차 항암 요법에 반응을 보이지 않거나 재발한 진행성 비소세포 폐암 환자를 대상으로 gemcitabine 과 vinorelbine 병합 요법을 시행하여 치료 반응율, 생존율 및 독성에 대해 연구하였다.대상 및 방법 : 2000년 12월부터 2003년 7월까지 고려대학교 의료원에 내원하여 비소세포 폐암으로 확진 받은 환자 중 진단 당시 IIIB, IV병기로 platinum을 기반으로 docetaxel 혹은 paclitaxel의 2제 복합 항암 요법을 1차 치료로 시행한 환자 중 진행하거나 재발한 환자들을 대상으로 gemcitabine과 vinorelbine 병합 요법의 치료 반응율, 생존율 및 독성을 분석하였다.
Backgroud : Lung cancer is the leading cause of cancer deaths in Korea and the number of lung cancer deaths is increasing. The higher response rates, decreased toxicity and improved performance status of the first-line treatments have resulted in an increased number of patients becoming candidates for second-line therapy. Several new antineoplastic agents, including gemcitabine, docetaxel and paclitaxel, have recently demonstrated second-line activity. This phase II study evaluated the efficacy and toxicity of gemcitabine and vinorelbine as combination chemotherapy for Korean patients with NSCLC as a second-line treatment. Methods : Sixty response-evaluable patients were enrolled from December 2000 to July 2003. We conducted a phase II study of a combination gemcitabine and vinorelbine chemotherapy for patients with histologically confirmed NSCLC that was stage IIIB and IV disease at the time of diagnosis, and the disease had progressed onward or the patients had relapsed after first-line platinum-based chemotherapy. They were treated with intravenous gemcitabine 1000mg/m2 and intravenous vinorelbine 25mg/m2 on days 1 and 8. This chemotherapy regimen was repeated every 3 weeks. Results : A total of 215 cycles of treatment were given and the mean number of cycles was 3.6 cycles. All the patients were evaluable for the toxicity profile. The response rate was 10% according to the WHO criteria. The median progression free survival was 3.8 months and the median survival time was 10.1 months. The 1-year survival rate was 32.9%. Grade III and IV neutropenia were seen in 20 (33.3%) and 7 (11.7%) patients, respectively. Conclusion : The combination of gemcitabine and vinorelbine is active and well tolerated as a second-line therapy for patients with advanced nonsmall cell lung carcinoma.

연구 배경 :우리나라에서는 다른 나라에 비해 약초 등을 이용해 만든 흡연대용품으로 금연을 시도하려는 흡연자들도 많고 이에 따라 여러 가지 다양한 제품 등이 판매되고 있는데 이들의 기관지, 폐에 대한 안정성에 관한 연구는 아직 부족한 상황이다. 특히 흡연자중 일부는 이런 금연 보조제를 사용하는 과정에서 이들을 상용하게 되어 시판되는 금연 보조담배의 장기적 사용시 인체의 안정성 여부에 대한 연구는 중요하리라 사료된다.
Background and Aims : Cigarette smoking induces an inflammatory response in the airways, which may play a key role in the pathogenesis of chronic obstructive pulmonary disease. Interleukin-6 (IL-6) is one of the cytokines that plays an important role in inducing bronchial inflammation. The aim of this study was to determine if the level of the pro-inflammatory cytokine, Interleukin-6 , is increased when the bronchial epithelial cells are exposed to a cigarette smoke extract (CSE) and an extract from stop smoking-aiding cigarettes, and examined the safety of these commercially available stop smoking-aiding cigarettes. Method : Bronchial epithelial cells were exposed to CSE from cigarette and stop smoking-aiding cigarettes for 24 hours. ELISA was used to measure the IL-6 levels in the supernatant from each condition. The IL-6 mRNA levels were measured by Taqman Real time RT-PCR. N–acetyl–L-cysteine(NAC) was added to each condition to determine if NAC can inhibit the release of IL-6 from the bronchial epithelial cells when they are exposed to CSE from cigarette and stop smoking-aiding cigarettes. Result : When bronchial epithelial cells were exposed to a CSE from cigarettes and stop smoking- aiding cigarettes, each type of CSE stimulated IL-6 production from the bronchial epithelial cells. The IL-6 mRNA level in the Bronchial epithelial cells was also elevated and NAC was found to inhibit the release of IL-6 from bronchial epithelial cells when they were exposed to the CSE from cigarettes and stop smoking-aiding cigarettes. Conclusion : Commercially available stop smoking-aiding cigarette can induce bronchial inflammation and can be harmful to smokers. Therefore, the safety of these cigarettes for smoking cessation should be evaluated. (Tuberc Respir Dis 2005; 59: 530-535)

The combination of oxaliplatin, 5-fluorouracil and leucovorin (FOLFOX) has recently been shown to be beneficial in advanced colorectal and gastric cancers. The side effects of this regimen include neutropenia, diarrhea and neurosensory toxicity. However, case reports on the pulmonary toxicities of this regimen are very limited. Especially, the development of pulmonary fibrosis has never been cited in the literature. Herein is reported the case of a patient treated with oxaliplatin, 5-fluorouracil and leucovorin combination chemotherapy in whom pulmonary fibrosis developed, but which improved after steroid pulse therapy.

Respiratory bronchiolitis associated interstitial lung disease is a rare condition among current or ex-smokers, which has features consistent with interstitial lung disease. The presentations are non-specific, but symptoms generally include a cough and dyspnea on exertion, and its pathology is characterized by the accumulation of pigmented macrophages within the respiratory bronchioles and adjacent air spaces, and is associated with mild thickening of the peribronchiolar interstitium. Recently, the case of a 54-year-old woman passive smoker, diagnosed as having respiratory bronchiolitis associated interstitial lung disease, was experienced at our institution.

Sarcoidosis is a rare systemic disorder with unknown cause that is characterized pathologically by non-caseating granuloma. The lung and mediastinal lymph nodes are almost always involved, and most patients experience acute or insidious respiratory symptom. Because sarcoidosis is an interstitial lung disorder involving the alveoli and bronchioles, the most common radiological finding is a reticularnodular lesion with lymphatic distribution. However, cavitation is quite rare.Sarcoidosis is also a major cause of hepatic granuloma in Western countries, accounting for 12% to 30% of cases. In most patients, the course of hepatic sarcoidosis is benign. However, chronic intrahepatic cholestasis or portal hypertension may develop in some patients. We report a case of sarcoidosis with cavitation and hepatic involvement. (Tuberc Respir Dis 2005; 59: 546-550)

Hemangiopericytoma is a rare neoplasm that originates from small peri-capillary spindle shaped cells called pericytes. The most common sites of origin are the thigh, the pelvis and the retroperitoneum. A primary pulmonary hemangiopericytoma is particularly unusual. However, more than 50% of hemangiopericytoma cases metastasize to the lungs, the bone, and the liver. A long-term clinical and radiological follow up is recommended due to the high risk of recurrence of a potential malignancy. We report a case of a metastatic hemangiopericytoma in the lung that had initially developed in the thigh of a 53 year-old woman 6 years ago. The authors emphasize the long-term follow-up of this type of rare sarcoma. (Tuberc Respir Dis 2005; 59: 551-555)
지방종은 아주 흔한 양성종양이지만 흉막에서 발생한 지방종은 드물다. 대부분 무증상이며 우연히 발견되는 경우가 많다. 단순 흉부 X-선 사진상 양성종괴의 모습을 보이며, 전산화 단층촬영에서 특징적인 균질한 지방으로 구성된 종양의 모습을 보인다. 흉막의 지방종의 경우 다른 종양이나 악성 종양을 배제하기 위하여 개흉술을 통한 종양의 제거를 해왔으나 수술 후 통증이 적고 회복이 빠른 흉강경으로 지방종을 제거한 53세 여자환자 1례를 경험하였기에 보고하는 바이다. (Tuberc Respir Dis 2005; 59: 556-560)
Bronchiolitis obliterans organizing pneumonia (BOOP) is often diagnosed in patients with pneumonia who respond poorly to antibiotics. BOOP is often idiopathic, and the etiology of the remaining cases has been attributed to a wide range of agents or medical conditions. When a patient develops the clinical symptoms characteristic of BOOP, the medical team must endeavor to determine the etiology of this disease because it can be treated with glucocorticoid and avoidance of the causative agent. In particular, if BOOP is diagnosed during or after chemotherapy for a malignancy, the possible culprit agent can be the anti cancer drugs but other drugs used for supportive care must be also be considered. We report a case of BOOP that arose after CHOP chemotherapy and a filgrastim injection in a patient with a diffuse large B-cell lymphoma. (Tuberc Respir Dis 2005; 59: 561-565)

Primary pulmonary non-Hodgkin’s lymphoma (NHL) account for 0.4% of all types of lymphoma. Most cases are of the mucosa-associated lymphoid tissue (MALT) type, low grade B-cell lymphoma, but cases of the T-cell type are rare. The radiological findings frequently show hilar or mediastinal lymphadenopathy, but lung parenchymal involvement is uncommon. Here, a case of a patient, who presented with fever, generalized erythema, diffuse pulmonary infiltration and pleural effusion, diagnosed as a peripheral T-cell lymphoma, is reported.
