A case of metastatic adenoid cystic carcinoma of the lung, originated from the trachea, was diagnosed by fine needle aspiration. Although the cytologic features of adenoid cystic carcinoma have been well described, it is easy to confuse adenoid cystic carcinoma with more common primary small cell neoplasms of the lung, i.e., small cell carcinoma, well differentiated adenocarcinoma, and carcinoid tumor of the lung. The features distinguishing adenoid cystic carcinoma from these neoplasms include 1) tight, globular, honeycomb pattern of cells, 2) acellualr basement membrane material in the lumen, and 3) cells lacking true nuclear melding and having bland chromatin pattern. The morphologic feature of metastatic adenoid cystic carcinoma in this case was so distinctive as to permit a definite diagnosis by aspiration cytology.

Background: Relationships between smoking and bladder neoplasms, one of the common malignancies, are well-known. Different smoking-related malignancies may occur together. In this study, we evaluated the stage and grade of bladder neoplasms in patients also featuring lung or larynx cancer. Materials and Methods: From January 2006 to February 2012, patients who underwent surgery for bladder neoplasms in our clinic were screened retrospectively. In the evaluation, 5 patients had larynx cancer and 20 patients have lung cancer in addition, all having been smoking for a long time. The bladder tumor stage and grade were investigated in these 25 cases. Results: Mean age of patients was 66.8 (49-78). In the evaulation, all of 5 patients who had larnyx cancer also had high grade urothelial cancer. One had T2 urothelial, and 3 T1 urothelial cancer. In the same way, all of the 20 patients with lung cancer also have high grade urothelial cancer, three T2, and 13 T1. Bladder cancer stage and grade were determined to be significantly increased in patients with concomitant bladder and lung or larynx cancer. Conclusions: In the patients who have smoking releated second malignancy, bladder cancer prognosis appears more aggressive. We now need a larger series and multi-center studies for understanding relevant pathophysiology.

식도, 위, 폐 그리고 구강에 동시 발생한 다발성 원발암에 대해 보고하고자 한다. 65세 남자 환자가 구강 내 종괴에 대해 상피세포암을 진단받고 광범위 절제술을 시행 받았다. 수술 후 정확한 병기 결정을 위해 시행한 검사에서 식도암, 위암 그리고 폐암이 추가로 확인되었다. 저자들은 상기 세가지암에 대하여 한 차례 수술로 근치적 절제술을 시행하여, 만족할 만한 결과를 얻었기에 이에 대해 보고하는 바이다.

식도암 환자에서 동시에 일차성 폐암이 발견되는 빈도는 2% 미만에 불과하며, 특히 두 질환 모두 예후가 나쁨으로 인해서 환자들이 근치적 절제술을 받을 기회를 놓치게 되는 경우가 많다. 그러나 환자를 신중히 선택한다면 폐와 식도의 중복암을 동시에 절제함으로써 좋은 결과를 가져올 수 있다고 생각한다. 저자들은 최근 식도와 폐의 일차성 중복암 환자 1예를 경험하였고, 쌍폐엽절제술과 Ivor Lewis 술식으로 일차성 근치적 절제술을 시행하여 좋은 결과를 얻었기에 국내 문헌상으로는 최초로 이를 보고하는 바이다.

본 연구는 항암화학요법을 받는 폐암환자의 불확실성과 불확실성 영향요인을 파악하기 위한 서술적 상관관계 연구이다. 연구 대상자는 일 대학병원에서 항암화학요법을 받고 있는 폐암환자 111명을 대상으로 하였다. 자료는 2014년 7월 25일부터 12월 31일까지 수집하였다. 수집된 자료는 SPSS Window 18.0 Program을 이용하였고, 빈도와 백분율, 평균과 표준편차, t-test, ANOVA, Scheffe test, median, standard deviations, Pearson's product moment correlation coefficient와 multiple regression analysis로 분석하였다. 연구 결과 항암화학요법을 받는 폐암환자의 불확실성은 평균 평점 2.61(${\pm}0.46$)점으로 다른 질병을 가진 환자의 불확실성 정도보다 높았다. 항암화학요법을 받는 폐암환자의 불확실성과 질병의 심각성, 증상의 일관성, 사건의 친숙성, 의료인에 대한 신뢰, 일상 활동 능력, 자기 효능감, 사회적 지지와의 관계를 분석한 결과 불확실성과 질병의 심각성 간의 상관계수는 .74(<.01), 불확실성과 증상의 일관성 간의 상관관계는 .27(<.01)이었다. 질병에 대한 심각성이 불확실성에 가장 영향을 미치는 변수로 나타났으며, 전체 설명력은 54%이었다. 이상에서 항암화학요법을 받는 폐암환자의 불확실성을 감소시키기 위한 간호중재가 필요할 뿐만 아니라 폐암 환자의 간호중재에는 질병의 심각성을 고려한 간호중재가 이루어져야 할 것이다.

Primary epithelial-myoepithelial carcinoma (EMC) of the lung is an extremely rare neoplasm that originates from submucosal bronchial glands and has been found in the salivary glands, breast tissue, and sweat glands. However, only a few cases in the respiratory tract have been identified. In the literature, most pulmonary EMCs have been reported to have developed endobronchially although a few EMC cases have been presented as intraparenchymatous tumors. We have identified a case of primary EMC that developed in the peripheral lung parenchyma.

A 71-year-old male patient visited Yeungnam University Hospital with abnormal chest computed tomography (CT) findings. Chest CT revealed multiple lung nodules and a posterior mediastinal tumor, the diagnosis of which was confirmed surgically. Magnetic resonance imaging (MRI) of the abdomen showed multiple small nodules, which were diagnosed as cavernous hemangioma in the liver based on the pathology results of the mediastinal and lung masses in combination with MRI findings. Cavernous hemangiomas are benign tumors that can occur throughout the body, mainly in the skin and subcutaneous tissue. The liver is the most common internal organ containing hemangiomas, whereas they are very rarely found in the lungs or mediastinum.

Objective: The aim of this study was to explore change and significance of serum carcino-embryonic antigen (CEA) before and after gefitinib therapy in patients with advanced non-small-cell lung cancer (NSCLC). Methods: Forty patients with advanced NSCLCs in III~IV stages were selected as study objects given gefitinib therapy combined with routine local radiotherapy until tumor progression or intolerable toxicity. After treatment, all patients were divided into control and non-control groups according to the results of evaluation based on RECIST 1.1 (Response Evaluation Criteria in Solid Tumors in 2009). Peripheral fasting blood from all patients was collected in the early morning and serum CEA was assessed by electro-chemiluminescence immunoassay (ECLIA) before and after treatment. Before treatment, patients were divided into high CEA group (CEA level > 50 ng/mL) and low CEA group (CEA level ${\leq}$ 50 ng/mL). Adverse reactions were noted and progression-free survival (PFS) in both groups was recorded after long-term follow-up that ended in December, 2012. Results: There was no difference between control and non-control groups in CEA level before treatment (P>0.05), whereas serum CEA decreased more markedly lower in the control group after treatment (P<0.01). All patients were divided into high CEA group (26) and low CEA group (14) according to serum CEA level. There was no statistically significant difference between two groups in adverse reactions (P>0.05) but the rate in former group was lower. Additionally, survival rates at 9 and 12 months in high CEA group were clearly higher than in the low CEA group (P<0.01). Conclusions: Serum CEA level can serve as a biochemical index to evaluate the prognosis with gefitinib treatment for NSCLC.

One hundred and thirteen patients underwent diagnostic fiberoptic bronchoscopy to exclude the presence of the lung cancer at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital from January 1979, to July 1980. Sixty five cases of these patients were studied for passible lung cancer by bronchoscopic examination. Patients varied in age from 24 to 75 years, with the highest concentration lying in the sixth decade (49%). male was predominated with sex ratio of 6.3 : 1. Forth three (75.4%) of 57 cases impressed as definitive, and 8(14.5%) of 55 cases impressed as negatibe lung cancer were subsequently proved to have had lung cancer. Positive bronchoscopic biopsy was found in 10 of 14 lung cancers which were situated in the left main bronchus and in 11 of 13 neoplasms involving the right upper lobe bronchus. epidermoid cell carcinomas were most frequent(82.4%). Bronchial biopsy detected 34(79%) of 43 hilar cancers and 1.3(59%) 22 periphera neoplasms, in those patients who had fiberoptic bronchoscopic examinations. In the present series of 65 cases, the lesion was so far advanced when first seen that it was considered inoperable in 31 (47.7%) and operable 34(52.3%), 19(55.9%) of these refusing surgery. fifteen were explored of whom 12(80%) were resectable.

Knowledge of molecular pathogenesis of non-small cell lung cancer has increased remarkably and changed the principles of treatment, especially during the past decade. These advancements have been limited mainly to adenocarcinoma of the lung. Recently, genetic alterations in squamous cell lung cancer (SQCLC) have been detailed and positive results of clinical trials using agents targeting these changes have indicated the potential for improved treatment outcomes for SQCLC.
