BACKGROUND Even after complete resection, recurrence of thymoma is not infrequently observed, and treatment of recurrent thymoma remains controversial. STUDY DESIGN One hundred and twenty-six patients underwent surgically complete resection for thymoma, and 24 of them had a recurrence. Surgical treatment of recurrent thymoma was attempted in 15 patients(More)
The aim of this study was to evaluate the usefulness of annual screening for lung cancer by low-dose computed tomography (CT) and the characteristics of identified lung cancers. Subjects consisted of 5483 general population aged 40-74 years, who received initial CT scans in 1996, followed by repeat annual scans for most subjects in 1997 and 1998, with a(More)
Seventy patients were studied after undergoing complete resection of thymoma to determine the effect of postoperative adjuvant mediastinal radiotherapy on prognosis, with regard to clinical stage, histological type, and pleural factor. Pleural factor was defined as follows: p0, no adhesion to the mediastinal pleura; p1, fibrous adhesion to the mediastinal(More)
The survival of patients with small cell lung cancer (SCLC) is related to T, N, M components, and early diagnosis and treatment of limited stage SCLC may improve survival. The objective of this study was to review the initial and annual repeat screening computed tomography (CT) images of all five patients with SCLC, encountered in our 1996-1998(More)
Vascular endothelial growth factor (VEGF) plays multifunctional roles in both the development of vasculature and the maintenance of vascular function. A decrease in VEGF reduces angiogenesis and induces apoptosis of vascular endothelial cells. Inhibition of the VEGF receptor causes endothelial cell apoptosis and emphysema. We postulated that VEGF(More)
An MR-pathologic correlation of nine intrathoracic neurogenic tumors (three neurofibromas, four schwannomas, and two ganglioneuromas) was performed to characterize their MR appearances. The three types of intrathoracic neurogenic tumor were found to have characteristic appearances on MR images that should be helpful when establishing the differential(More)
OBJECTIVE The authors determined the effect of postoperative mediastinal irradiation in preventing local and pleural recurrence of thymoma. SUMMARY BACKGROUND DATA The role of mediastinal irradiation after incomplete resection or biopsy of an invasive thymoma is well established. However, routine use of adjuvant mediastinal irradiation for patients with(More)
Early diagnosis and treatment are important for improvement of the low survival rate of patients with lung cancer. The objective of this study was to evaluate the long-term survival rate of patients identified to have lung cancer by our population-based baseline and annual repeat low-radiation dose computed tomography (low-dose CT) screenings, conducted in(More)
A rupture of the ascending aorta which occurred in a woman on the 13th postoperative day following a right upper lobectomy with mediastinal lymph node dissection for lung cancer is reported herein. Fortunately, the patient was rescued from a cardiac tamponade and hemothorax by emergency operation. The operative findings suggested a traumatic rupture of the(More)
In twelve patients with severe emphysema who underwent lung volume reduction surgery (LVRS), we assessed the results of dyspnea scale, pulmonary function, 6-minute walk distance (6MD), and thoracic movement prior to and 6 months following LVRS. Postoperatively, forced expiratory volume (FEV1), maximum inspiratory mouth pressures (MIP), maximum expiratory(More)
