  • Overall 25,095 cases of general thoracic surgery were analysed, which were performed by 48 institutes in Korea during recent 6 years[242 hospital-years]. The proportions of tumorous disease and infectious disease to be operated were 6,864 cases[27.4%] and 6,775 cases [27.0%], The most common organ involved for operation was lung-bronchus 16,542 cases [69.5%], and remainders were pleura 2,500 [10.0%], esophagus 2,433[9.7%], mediastinum 1,902[7.6%], chest wall 1,297 [5.2%], and diaphragm 421 [1.7%] in order. Among 6,864 cases of tumorous diseases, the most common causes for operation were lung-bronchus tumor 3132 cases [45.6%] and most of them were lung cancer 2,731 cases [88.7%]. In the 2,019 cases of primary lung cancer with known cell type, squamous cell carcinoma 1,296 cases [64.2%] and adenocarcinoma 460 cases [22.8%] were the most. The common types in the 1,207 cases of mediastinal tumor with known cell type were neurogenic tumor 348 cases [28.8%], thymoma 311 [25.8%], and teratoma 252[20.9%]. The annual cases of operation for tumorous disease including malignant tumor were increased steadily. Operation for infectious lung diseases [including bronchiectasis and tuberculosis] were about twice common than infectious pleural disease [i.e. empyema], and operations for tuberculous disease occupied about half cases of infectious lung disease. In 11,456 cases of other disease entities, excluding tumorous and infectious disease, there were bullous lung disease 9,074 cases[79.2%], benign esophageal disease 484[4.2%], myasthenia gravis 356[3.1%], chest wall deformity 483[4.2%], and diaphragmatic lesion 421[3. 7%] in order. We propose that above results for inquiry can be used as the basic data of general thoracic surgery in Korea.

  • Background & Objectives: Gastric cancer is a leading cause of cancer-related deaths in both sexes in Iran. This study was designed to assess upper GI endoscopic findings among people > 50 years targeted in a mass screening program in a hot-point region. Methods: Based on the pilot results in Guilan Cancer Registry study (GCRS), one of the high point regions for GC-Lashtenesha- was selected. The target population was called mainly using two methods: in rural regions, by house-house direct referral and in urban areas using public media. Upper GI endoscopy was performed by trained endoscopists. All participants underwent biopsies for rapid urea test (RUT) from the antrum and also further biopsies from five defined points of stomach for detection of precancerous lesions. In cases of visible gross lesions, more diagnostic biopsies were taken and submitted for histopathologic evaluation. Results: Of 1,394 initial participants, finally 1,382 persons (702 women, 680 men) with a mean age of $61.7{\pm}9.0$ years (range: 50-87 years) underwent upper GI endoscopy. H. pylori infection based on the RUT was positive in 66.6%. Gastric adenocarcinoma and squamous cell carcinoma of esophagus were detected in seven (0.5%) and one (0.07%) persons, respectively. A remarkable proportion of studied participants were found to have esophageal hiatal hernia (38.4%). Asymptomatic gastric masses found in 1.1% (15) of cases which were mostly located in antrum (33.3%), cardia (20.0%) and prepyloric area (20.0%). Gastric and duodenal ulcers were found in 5.9% (82) and 6.9% (96) of the screened population. Conclusion: Upper endoscopy screening is an effective technique for early detection of GC especially in high risk populations. Further studies are required to evaluate cost effectiveness, cost benefit and mortality and morbidity of this method among high and moderate risk population before recommending this method for the GC surveillance program at the national level.

  • Bronchial adenoma, firstly described by Muller[1882] had been reported on the subject stressed their benign nature prior to 1940`s, but these tumors including carcinoid tumor, mucoepidermoid carcinoma, adenoid cystic carcinoma, pleomorphic adenoma are now known to possess the various degree of malignant natures from benign course, low grade malignant potential to distant lymphatic or hematogenous metastasis or combination. Although histologically diffeerent, four varieties except carcinoid tumor which is a spectrum of neu-roendocrine tumor originating Kulchitsky cell of the bronchial epithelium and form the part of the APUD tumor spectrum, are morphologically and in many respects clinically similar to the corresponding tumor of the salivary gland is a specific varient of adenocarcinoma that occurs most commonly in the major and minor salivary gland and less frequently tra-cheobronchial tree, esophagus etc. To better understand the clinical characteristics and assess more precisely the malignat nature of bronchial adenoma, we studied 17 cases of bronchial adenoma, which had been experienced at the Department of Thoracic and Cardiovascular surgery of Catholic University Medical College from April 1977 to september 1991. Seventeen cases of bronchial adenoma consist of 2 carcinoid tumors, 6 adenoid cystic carcinomas, 8 mucoepidermoid carcinomas and one pleomorphic adenoma. There is a slight predominace of male patients[10/17] and the age of pt studied varied with a higher incidence occurring between the ages of 40 years and 60 years[mean age, 46.5 years]; the youngest being 15 years and oldest 69 years. Their leading complaints were hemoptysis[4], exertional dyspnea[8], fever & chilness [4], and symptoms mimicking the bronchial asthma[4]. Diagnosis was aided by the radiologic studies such as chest X-ray, polytomography, CT scan, brochography and bronchoscopy. The preferred locations of fumor were in the trachea[4], main stem bronchus[3], bronchus intermedius[3], bronchus of RUL[2], LUL[1], RLL[1], LLL[3] with no peripheral location. Modalities of treatments were single or combination of surgical resection, radiation therapy, chemotherapy. Complete resections were permitted in 12 cases with late recurrences of 4 cases ranging from 6 months to 10 years: pneumonectomy[4], lobectomy[4], bil-obectomy[2], sleeve resection[2]. Gross findings of resected specimens in 14 cases showed that 4 cases were polyp-like pedunculated mass[entirely intraluminal mass] with intact mucosa, 8 cases were broad-bas-ed sessile mass[predominatly intraluminal] and the main portions were located below the mucosa similar to tip of iceburg[predominantly extraluminal] in 2 cases. Follow-up information was availble in all 17 cases ; eight were alive without evidence of disese ranging from 1 month to 13 years. But seven cases died of the causes related to tumor[6 cases within 12 months, one case 10 years after pneumonectomy]. We concluded that 8 cases[47%] of 17 cases were metastasizing bronchial adenoma and precise survival rate cannot be answered by the scanty materials available for study.

  • Background: Northern Iran counts as one of the highest prevalence regions for esophageal cancer (EC) worldwide. This study was designed to assess the epidemiologic aspects of EC in north central and northwest Iran over a 10 year period. Materials and Methods: The Guilan cancer registry study (GCRS) is a population-based cancer registry study featuring retrospective (1996-2003) and prospective (2004-2005) phases. A detailed questionnaire based on WHO standards for cancer registratration was applied to gather the required information. Two trained physicians coded information using ICD-O-3 in close coordination with an expert pathologist. Results: A total of 19,936 cases of malignancy (mean age $55.4{\pm}18.0$ years, range: 1-98 years) were registered, including 1,147 cases (670 males, 447 female; mean age: $64.0{\pm}11.5$ years) of EC. In 1996 the male/female ratio among patients with EC was 1.25 which increased to 1.53 in 2005. The lower third of the esophagus still remained the most common site of tumors. The average age-standardized rate (ASR) was 6.9 and 4.1 per $10^5$ men and women, respectively. In 1996, the ASRs were 7.2 and 5.2 per $10^5$ men and women which decreased to 6.9 and 4.1 per $10^5$ in 2004-2005. Squamous cell carcinoma (SCC) was the most prevalent histological subtype of EC accounting over 80% of cases. Conclusions: However the prevalence of adenocarcinoma (ADC) showed an increase to 18.4%. Guilan province may be considered a relatively low incidence region for EC.

  • 목적: 위식도접합부선암의 임상병리학적 특성은 서구와 아시아 간의 많은 차이를 보인다고 알려져 있다. 그러나, 한국의 경우 위식도접합부선암의 유병율이 매우 낮고 이에 대한 연구 또한 부족하다. 따라서 저자들은 우식도접합부선암의 Siewert 분류에 따른 임상병리학적 특성을 조사하여 서구와 다른 국내 위식도접합부선암의 특성을 연구하고자 하였다. 대상 및 방법: 2004년 5월부터 2008년 2월까지 본원에서 위암으로 수술을 시행 받은 환자들을 대상으로 수술소견 및 병리 사진을 토대로 Siewert 분류법에 따라 위식도접합부선암을 분류하고, 의무기록을 바탕으로 환자들의 임상병리학적 특성들을 조사하였다. 결과: 위식도접합부선암은 전체 1,778예 중 70예(3.9%)였다. Siewert 1형은 3예(4.3%)로 매우 드물었으며, 2형과 3형이 각각 30예(42.8%) 37예(52.8%)였다. 2형이 3형에 비하여 평균연령이 높았으나(64세 vs 59세, P=0.049), 남녀비에는 차이가 없었다. 2형과 3형간에 Barrett 식도의 발현 정도나 Lauren 분류의 차이는 없었으나, 저분화암의 빈도는 3형에서 유의하게 높았다(P=0.045). 68예(97.1%)에서 근치적 절제가 시행되었으며, 각 아형간에 TNM 병기의 차이는 없었다. 결론: 국내의 위식도접합부선암은 매우 드물며 특히 1형의 유병율이 매우 낮다. 본 연구에서 서구의 보고와 부분적으로 일치하지 않는 병리학적 특성을 보였다. 향후 보다 많은 환자들을 대상으로 한국인의 위식도접합부선암의 특성을 연구할 필요가 있다.

  • 배경: 식도암의 조기 발견과 수술은 완치의 기회를 제공하지만 최근의 수술술기와 방사선 치료, 항암요법의 발달에도 불구하고 그 장기 성적은 만족할 만한 수준에 있지 못하다. 고려대학교 구로병원 흉부외과에서는 1992년부터 2002년 7월까지 10년간에 걸쳐 식도암의 근치수술을 시행한 환자를 대상으로 후향적 조사를 하였다. 대상 및 방법: 대상 환자는 식도암으로 외과적 처치가 필요하였던 129예 중 근치 수술을 시행 받은 68예의 경우만을 대상으로 하였다. 총 68명의 환자에서 남 여 비는 59:9, 나이는 $61\pm7.4$세였고 주된 증상은 연하곤란, 통증, 체중 감소 등이었다 식도암의 위치는 상부 4예, 중부 36예, 하부 20예, 위식도 경 계부위 8예였고, 세포형은 편평상피세포암이 대부분으로 60예, 선암이 7예, 흑색포암이 1예 있었다. 5명의 환자에서는 수술 전 항암 요법을 시행하였다. 결과 : 종양의 병기는 1기가 7예, 2A기가 25예, 2B기가 12예, 3기가 17예, 4기가 7예였다. 식도대용으로 사용한 장기는 위가 대부분으로 62예, 대장이 6예 있었고, 경부에서 문합이 28예, 흥부에서 문합이 40예 있었다. 문합은 자동 봉합기 사용이 24예, 수기 봉합이 44예였다. 수술 후 조기 합병증으로는 문합부 누출이 3예 있었지만 큰 문제없이 치료되었다. 누출된 예의 연결 방법은 자동 봉합기 사용이 2예, 수기 봉합이 1예로 통계학적으로 의미 있는 차이는 없었다. 2예에서 급성 간부전과 패혈증으로 인해 조기사망하였다. 수술 후 23명의 환자에서 평균 수술 후 $3\~5$개월 사이 항암 주사 및 방사선 요법의 병행 요법을 시행하였고 추적 관찰은 55명$(80.88\%)$의 환자에서 가능하였다. 기간은 1달에서 76개월 사이로 평균 $33.73\pm22.18$개월이었고, 이들 환자의 병기는 각각 1기가 5예, 2A기가 21예, 2B기가 9예, 3기가 15예, 4기가 5예였다. 수술사망환자를 포함한 추적관찰이 가능하였던 전체 환자의 생존율은 1년 $58.43\pm6.5\%$, 3년 $35.48\pm7.5\%$, 5년 $18.81\pm7.7\%$였고 최장 생존환자는 병기 1기로 108개월 째 추적관찰 중이다 세포형별, 성별, 문합위치별, 암의 위치, 술 전, 술 후 병합 요법의 시행과 생존율의 차이에는 통계학적 유의성이 없었지만 병기별, 71, 2, 3, 4 군간의 비교, N0과 Nl군간의 생존율의 차이는 통계학적 유의성이 있었다(p<0.05). 결론: 대개 식도암에 대한 치료는 고식적 치료가 많은 환자에서 이루어지고 있지만 조기 진단 및 적극적인 수술적 절제, 적절한 술 후 치료 등으로 장기 생존율을 높일 수 있다고 생각된다
