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)
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)
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)
BACKGROUND We aimed to examine associations among serum 25-hydroxyvitamin D (25OHD) levels, 1,25-dihyroxyvitamin D (1,25OHD) levels, vitamin D receptor (VDR) polymorphisms, and renal function based on estimated glomerular filtration rate (eGFR) in patients with type 2 diabetes. METHODS In a cross-sectional study of 410 patients, chronic kidney disease(More)
PURPOSE 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)(More)
BACKGROUND Malignant pleural mesothelioma is a challenging disease with regard to diagnosis and treatment; early and accurate diagnosis would lead to appropriate therapeutic strategies, including extrapleural pneumonectomy. Immunohistochemistry has proven valuable for the diagnosis of the most common epithelioid mesothelioma, although it is often difficult(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)
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)
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)
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)
