PURPOSE To compare low-dose spiral computed tomography (CT) with radiography of the chest for the screening and detection of small peripheral lung cancers in a high-risk population. MATERIALS AND METHODS Posteroanterior and lateral radiographs and low-dose spiral CT scans were obtained twice a year from September 1993 to April 1995 in 1,369 individuals (a(More)
A new TNM staging system was proposed and the previous system has been revised recently. To evaluate the new TNM staging system for lung cancer, we analyzed records of 1737 patients who underwent pulmonary resection at the National Cancer Center Hospital, Tokyo. With regard to clinical stages, three patients had occult carcinoma; 821 patients had stage I(More)
Between 1966 and 1996, 17 patients, comprising 1 child and 16 adults, underwent surgical treatment for bronchogenic cysts at the National Cancer Center Hospital. The bronchogenic cysts were located in the mediastinum in 11 patients and in the pulmonary parenchyma in 6. Of the 17 patients, 5 (29.4%) manifested symptoms, being more frequently seen in those(More)
During a 28-year period, 52 bronchopleural fistulas developed after pulmonary resection of 49 primary and three recurrent lung cancers at the National Cancer Center Hospital, Tokyo. During the same period there were 2359 pulmonary resections for primary lung cancer; the prevalence of bronchopleural fistula was 2.1%. Multivariate analysis on 15 variables in(More)
By means of lymph mapping, the prognosis significance of lymph node metastasis in lung cancer was studied in 270 patients who had undergone radical operations--pulmonary resection combined with complete mediastinal lymph node disection, which is used for patients in whom all cancer could thereby be ablated. Mediastinal lymph node metastasis was found in 64(More)
Among patients with primary lung cancer who were admitted to the National Cancer Center Hospital from July 1987 to April 1988 for surgical treatments, 132 underwent preoperative transesophageal endoscopic ultrasound examination (EUS) on mediastinal lymph nodes. Of the 132 patients, 101 were pathologically evaluated and studied in this article. A GF-UM2(More)
BACKGROUND While pulmonary nodules can be substantially divided into solid and ground-glass opacity (GGO) ones on CT image, they have different biological natures which could cause false positive or false negative to diagnose malignancy on positron emission tomography with fluorodeoxyglucose (FDG-PET). To determine the effectiveness of PET for small(More)
BACKGROUND A new TNM staging system was proposed, and the previous system was revised in 1997. METHODS To evaluate the new TNM staging system for lung cancer, records of 3,043 lung cancer patients who underwent pulmonary resection at the National Cancer Center Hospital, Tokyo, were analyzed. RESULTS With regard to clinical stages, 3 patients had occult(More)
Restriction length fragment polymorphism of the L-MYC gene was examined in DNAs from lung cancer tissues and normal tissues of 51 Japanese patients with lung cancer. In individual patients, no difference was seen between the restriction length fragments of the two alleles of L-MYC [6-kilobase (kb) and 10-kb fragments in EcoRI digests] in lung cancer tissues(More)
OBJECTIVE Although several studies have shown that video-assisted thoracic surgery (VATS) for major pulmonary resection is less invasive than open thoracotomy, VATS for lung cancer has been performed in only a limited number of institutions. We aimed to review our experience of VATS for major pulmonary resections, and to determine its safety and adequacy in(More)
