STUDY OBJECTIVES Controversy regarding the most suitable surgical approach for treating malignancies of the lung is a matter of continuous discussions. "Complete" video-assisted thoracic surgery (VATS) that is performed using only the vision of a monitor is generally limited to lung resections of minimal difficulty. With the great interest in minimally(More)
OBJECTIVES Pleural lavage cytology is the microscopic study of cells obtained from saline instilled into and retrieved from the chest during surgery for non-small-cell lung cancer. The aims of this study were to collate multi-institutional individual patient data for meta-analysis to determine independence as a prognostic marker and to characterize the(More)
BACKGROUND Improved radiologic imaging provides earlier detection of non-small cell lung cancer, but controversy exists regarding the need for complete lymph node dissection. This study was designed to evaluate the possibility of lesser mediastinal dissection for early-stage lung cancer. METHODS Selective mediastinal dissection is defined as follows:(More)
OBJECTIVE The aggressiveness of small adenocarcinomas has not been fully evaluated using integrated positron emission tomography/computed tomography. We investigated malignant aggressiveness according to positron emission tomography/computed tomography, high-resolution computed tomographic findings, and the proportions of pathologically defined(More)
The role of surgical treatment for malignant pleural mesothelioma (MPM) continues to be controversial. We carried out a retrospective review of the prognosis in patients who had radical surgery for MPM. Of 87 consecutive patients on whom surgical exploration for biopsy-proven MPM was performed, 31 patients underwent extrapleural pneumonectomy (EPP) and 34(More)
To clarify the role of plasminogen activator inhibitor type 1 (PAI-1) in postburn hypercoagulation, we assayed the plasma levels of tissue-type plasminogen activator (t-PA) antigen, total PAI-1 antigen, and total t-PA-PAI-1 complex in 15 burned patients. The total body surface area of the burn injury ranged from 30 to 80%. Serial blood samples were(More)
The education of surgical trainees should be based on an accurate evaluation of their surgical skill levels. In our hospital, the Objective Structured Assessment of Technical Skills (OSATS) is used for this purpose. We conducted this study to demonstrate the validity and accuracy of the OSATS for assessing surgical skills in the operating room (OR) setting.(More)
OBJECTIVE Segmentectomy is an anatomic parenchyma-sparing resection that is recently being performed for small-sized lung carcinoma and constitutes a useful procedure in a thoracic surgeon's armamentarium. We have generated a new technique that improves the identification of the intersegmental border and whose clinical utility we evaluate in this study. (More)
OBJECTIVE This study evaluates the prognostic significance of [18F]-fluoro-2-deoxyglucose positron emission tomography/computed tomography findings according to histological subtypes in patients with completely resected non-small cell lung cancer. METHODS We examined 176 consecutive patients who had undergone preoperative(More)
BACKGROUND The prognosis of lepidic predominant lung adenocarcinoma is favorable. We postulated that lepidic predominant tumors might not require postoperative adjuvant chemotherapy. The present study aims to determine whether lepidic component occupancy affects overall survival after postoperative adjuvant chemotherapy for lung adenocarcinoma. METHODS(More)
