OBJECTIVES Ground-glass opacities are typically difficult to inspect and to palpate during video-assisted thoracic surgery. We therefore examined whether ultrasonographic assessments could localize ground-glass opacities and help to achieve adequate resection margins. METHODS An intraoperative ultrasonographic procedure was prospectively performed on 44(More)
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 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)
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)
RATIONALE AND OBJECTIVES To evaluate the performance of custom-made software designed to quantify volume and weight of focal portions of lung tumors in regions of interest (ROI) and volume of interest on thin-section computed tomography (CT) images by stratum of CT values. METHODS AND MATERIALS Volume and weight of lung portions were measured(More)
RATIONALE Neutrophils accumulate in pulmonary capillaries during acute inflammation. Initial events in injury recognition and sequestration do not occur through selectin-mediated rolling. Cytoskeletal rearrangements, as assessed by submembrane F-actin rims, result in poorly deformable neutrophils that may not pass through capillaries. OBJECTIVE To test(More)
OBJECTIVES Cases of lung cancer with pure ground-glass nodules (GGNs) have been detected with increasing frequency since the advent of computed tomography (CT), and growth is sometimes noted during follow-up. The objective of this study was to evaluate the potential predictive factors for pure GGN growth. MATERIALS AND METHODS We retrospectively examined(More)
RATIONALE AND OBJECTIVES To define high-resolution computed tomography (HRCT) features of lung cancers detected by computed tomography (CT) screening according to histopathology and prognosis. METHODS AND MATERIALS Tumor size, CT value, morphology, and tumor volume doubling time (TVDT) were determined for 10 atypical adenomatous hyperplasias (AAH) and 50(More)
Nine cases of thymic carcinoma (5 males and 4 females) were operated in our hospital between 1990 and 1998. These cases included 4 squamous cell carcinomas, 2 small cell carcinomas, 2 undifferentiated carcinomas and one adenocarcinoma. Preoperative chemotherapy were performed in 3 cases. All cases underwent median-sternotomy followed by mediastinal(More)
Technetium-99m human serum albumindiethylenetriaminepentaacetic acid (HSA-DTPA) lymphoscintigraphy with single photon emission computed tomography combined with integrated low-dose computed tomography (SPECT/CT) is useful for evaluating chylothorax. We report a case of chylothorax that occurred 2 months after childbirth in a 24-year-old woman.(More)
