This report is an analysis of 60 cases of primary mediastinal tumors and cysts which were experienced in chonbuk National University Hospital, Wonkwang University Hospital and Chonju Presbyterian Medical Center from january 1985 to October 1990. The result was summarized like this; 1) Age distribution was various from ages of 5 to 75 years. There were 26 males and 34 females, sex ratio of patients was 1: 1.3 (M:F). 2) The most common chief compliant was dyspnea (21 cases, 35%) and followed by chest pain, coughing and chest discomfort. 17 patients (28%) were asymptomatic. 3) The most common primary mediastinal tumor was thymoma, which comprise 28% (17 cases) of all our cases and followed by neruogenic tumor (14 cases, 23%) and germ cell tumor (11 cases, 18%). 4) The incidence of malignancy of all case was 22%; 2 cases were asymptomatic and the most common malignancy was malignant lympoma (5 cases, 38.5%). 5) The anterior mediastinum was the most common tumor location and followed by posterior and middle mediastinum. Anterior mediastinal tumors mainly consisted of thymomas and germ cell tumors and posterioc mediastinal tumors mainly did neurogenic tumors. 6) Of 60 cases, 21 cases were confirmed histopathologically by percutaneous transthoracic needle lung biopsy. 7) Of 60 cases, 40 cases were received radical tumor resection.

This report is a analysis of 72 cases of mediastinal tumors which are originated in mediastinum or probably metastasized from other organs, and classified on the basis of histopathological types. And all are experienced in the Depart. Thoracic and cardiovascular Surgery, National Medical Center from 1959 to April 1976. Among these cases, 58 cases were confirmed by histopathologically, and remained 14 cases were considered as mediastinal tumor by clinically and roentgenologically. In this series, dermoid cyst and teratoma was most frequent tumor among histopathologically confirmed cases(27.6%), and thymoma 20.7%, neurogenic tumors 17.2%, carcinoma 19%, lymphoid tumor 8.6% and others was 5.9%. The cases of not verified histopathologically were 14 cases. The main clinical symptoms were dyspnea on exertion or orthopnea (62.55%), productive or irritative cough (59.77%), decreased breathing sound (43. 09%). S.V.C syndromes was seen in 25.02%, and there were no definitive symptom in 4.2% of all cases. The main treatment method was surgical removal and irradiation therapy.

Two cases of benign mediastinal tumor were treated by complete resection under the video-thoracoscopic guidance. The procedure has been performed on the 2 patients, allowing definite treatment and was less invasive than standard surgical treatment. The 2 patients have been benefited by decreased postoperative pain, reduced scarring of the skin and rapid recovery. Two patients had benign mediastinal tumors; teratodermoid on anterior mediastinum and neurilemmoma on posterior mediastinum. There were no operative death and complication, median hospital stay was four days.

The mediastinoscopy was a well known useful diagnostic tool for detection of certain mediastinal tumors ,mediastinal lymph nodes invasion by bronchogenic carcinoma and metastatic cancer. A total of 33 cases of mediastinoscopies were reviewed, which were experienced at Chon Buk National University Hospital from August,1980 to October 1991. Mediastinoscopy was performed through anterior or parasternal approach in 18 cases, cervical approach in 14 cases and both in 1 case. In 12 cases which were used for preoperative stagig of lung cancer, 10 cases[83.3%] had the positive biopsy results at mediastinal nodes. In 11 cases for diagnosis of lymph nodes and masses with unknown lung lesion, small cell carcinoma revealed in 3 cases,squamous cell carcinoma in 2 , adenocarcinoma in 1 case and the others were had the negative biopsy results. In 10 cases for diagnosis of mediastinal tumors, lymphoma revealed in 2 cases, malignant thymoma in 2, sarcoidosis in 2, tuberculous granuloma in 1, mesothelioma in 1, metastatic cancer with unknown origin in 1 case. Thoracotomy was performed in 3 cases of lung cancers, 2 patients with negative biopsy results in preoperative staging and 1 patient with subcarinal lymph node involvement only. Bleeding complications during mediastinoscopy were developed in 2 cases, managed by anterior mini-thoracotomy.

척삭종은 원시 척삭(primitive notochord)의 잔유물에서 발생하여 서서히 성장하는 악성종양으로 매우 드문 종양이다. 뿐만 아니라, 후총격동 종양으로 나타나는 흉부 척삭종은 보고된 모든 척삭종의 1∼2％만을 차지하고 있다. 이러한 척삭종은 불완전한 절제가 될 경우 국소재발과 원격전이를 하여 예후가 불량하지만, 완전 절제와 수술 후 보조적 방사선 요법이 병행된 경우에는 완치를 기대할 수 있다. 삼성서울병원 흥부외과에서는 최근, 후종격동 종양으로 나타난 흉부 척삭종을 완전절제술 및 술 후 보조적 방사선요법을 시행하여 2년 동안 재발 및 전이가 없는 예를 경험하였기에 보고하는 바이다

저자 등은 아무런 증상이 없던 37세 남자에서 후종격동에서 발생하였고 진단당시 증상이 없었으며 암표식자의 증가를 동반하지 않았던 비전형적인 원발성 종격동 태생암 l례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

대전 을지병원 흉부외과에서는 1986년 1훨부터 1995년 4월까지 원발성 종격동종양 및 낭종으로진 단된 43명의 환자에 대해서 수술적 치료를 시행하였다. 남자환자가 19례, 여자환자가 24례였다 연령분포는 4세 부터 68세까지이고 평균연령은 31.3세였다. 가장 흔한 증상은 호흡곤란(48.8 %)이고, 그외 흉부불쾌감(39.5 %), 기침 (34.9 %), 흥통(23.3 %) 순이 었다. 가장 빈발한 종양의 위치는 전종격동이고, 후종격동, 중종격동 순이 었다. 병 리 학적으로 기형종이 가장 흔하고, 신경종, 낭종, 흉선종, 임파종 순이 었다. 가장 유용한 진단방법은 단순흉부X-선이고 최종진단은 단지 수술로써 내려졌다. 양성종양은 전례에서 완전절제 되 었고 악성종 양은 수술후 화학요법 및 방사선요법을 병용하였다. 수술후 합병증은 7례 (16.3 %)에서 있었고 술후 사망은 1 례도 없었다.

배경: 이 연구는 비소세포암 환자에서 종격동 임파선 전이 여부를 정확히 예측하기 위해서 PET/CT에서 종격동 임파선과 폐종괴의 FDG 섭취비와 폐종괴의 Glut-1 발현 정도를 이용하여 분석 하고자 하였다. 대상 및 방법: PET/CT에서 폐종괴와 종격동 임파선에서 측정할 수 있는 정도의 FDG섭취가 있는 환자를 대상으로 하였다. FDG 섭취비는 종격동 임파선의 섭취를 폐종괴의 섭취로 나누어 구하였다. 폐종괴의 Glut-1 발현은 발현 면적으로 나타내었다. 결과: 폐종괴와 종격동 임파선의 mSUV값은 악성군에서 각각 $7.4{\pm}2.2$와 $4.2{\pm}2.2$, 양성군에서 각각 $7.6{\pm}3.7$와 $2.8{\pm}6.9$였다. FDG의 섭취비는 악성군과 양성군에서 각각 $0.58{\pm}0.23$과 $0.45{\pm}0.20$ (p<0.05)였다. FDG 섭취비와 Glut-1 발현 정도를 결합한 모델 중에서 {p/(1-p)}=ratio+glut+ratio${\times}$glut의 식으로 표시된 모델이 FDG 섭취비만을 이용한 모델 보다 정확히 종격동 임파선의 악성 정도를 예측할 수 있었다. 결론: 염증성 폐질환의 병력이 있는 일부 폐암 환자에서 Glut-1 발현 정도를 고려한 FDG 섭취비를 분석한 모델은 종격동 임파선의 악성 정도를 정확히 진단할 수 있다.

A total of 178 patients with primary lung cancer who had undergone complete resection of the tumor in combination with complete mediastinal lymphadenectomy were reviewed at the Department of Thoracic and Cardiovascular Surgery of Yonsei Medical Center from January 1980 through July 1989. Materials; 1. There were 45 men and 33 women ranging of age from 25 to 78 years with a mean age of 55.4 years. 2. Histological types were squamous carcinoma in 115 cases [64.6%] adenocarcinoma in 42 cases [23.6 %], bronchioloalveolar carcinoma in 9 cases [5.1%], large cell carcinoma in 8 cases [4.5 %] and small cell carcinoma in 4 cases [2.2%] Results were summarized as follows: 1. The size of primary tumor was not directly proportional to the frequency of mediastinal lymph node metastasis. [P =0.0567] 2. The histologic types of the primary tumor did not related to the incidence of mediastinal lymph node metastasis. [P >0.19] 3. The chance of mediastinal lymph node metastasis in the case with lung cancer located in right middle lobe[31.8%, N=22] and left lower lobe [31.4%, N=32] were the highest and the lowest was the one located in right lower lobe, while over all incidence of mediastinal lymph node metastasis in this series was 25.4 % [N=55]. 4. The rate of mediastinal lymph node metastasis without evidence of regional and hilar lymph node metastasis was 13%. [N=23] The chance of mediastinal lymph node involvement without N1 lymph node metastasis was 16.3 % [N=17] in both upper lobes and 8.2 % [N=6] in both lower lobes. It was statistically significant that the tumors in the upper lobes had greater chance of the mediastinal lymph node metastasis without N1 than the tumors in the lower lobes. 5. In this series majority of the patients with lung cancer the mediastinal lymph node metastasis from the tumor in each pulmonary lobes usually occurs via ipsilateral tracheobronchial and paratracheal lymphatic pathway. Especially the lung cancer located in lower lobes can metastasize to subcarinal, paraesophageal and inferior pulmonary ligamental lymph node through the lymphatic pathway of inferior pulmonary ligament. It can be speculated that in some cases of this series otherwise mediastinal lymph node metastasis can also occur with direct invasion to the parietal pleura and to the mediastinal lymph node via direct subpleural lymphatic pathway .
