Background
A 64-slice multidetector computed tomography (MDCT) is well known to be a useful noninvasive form of angiography for the general population, but not for certain patients with diabetes. The aim of this study was to investigate the diagnostic accuracy and usefulness of 64-slice MDCT coronary angiography for detecting coronary artery disease in Korean patients with type 2 diabetes mellitus (T2DM).

Diagnostic Accuracy of 64-Slice MDCT Coronary Angiography for the Assessment of Coronary Artery Disease in Korean Patients with Type 2 Diabetes.

Primary liposarcoma of the lung is an extremely rare disease. To date, only 14 cases have been reported in the literature. We experienced a case of myxoid liposarcoma of the lung treated by surgery. The tumor was well-defined, solid, lobulated mass measuring 3.5×2 cm, involving the bronchus of the left lower lobe. Microscopically, myxoid liposarcoma was identified. The fluorescence in situ hybridization confirmed the presence of a reciprocal translocation involving DNA damage-inducible transcript 3 (DDIT3) and fused in sarcoma (FUS) genes. The patient is still alive with no recurrence or metastasis at the time of writing this report (on 20 months postoperatively). To our knowledge, this is the first cytogenetic case report of pulmonary myxoid liposarcoma.

A solitary fibrous tumor (SFT) is a mesenchymal fibroblastic tumor inside the pleura, for which complete surgical resection is the standard treatment. For large SFTs, preoperative identification of tumor-feeding vessels using angiography is important for achieving complete resection without unexpected operative bleeding. Extensive adhesions can make resection difficult in a limited operative window, and pulmonary resection may be required to achieve complete SFT resection. Herein, we report successful resection of a large pleural SFT in a 39-year-old man without any complications using a 2-stage approach, in which ligation of the feeding vessels through small another operative window was the first step.

Primary neoplasms of the great vessels (aorta, pulmonary vessels, and vena cava) are rare. The pathogenesis of these tumors is still unclear, and it has been suggested that these tumors arise from the mesenchymal cells of the muscle anlage in the bulbus cordis in cases of pulmonary artery sarcoma. Most primary sarcomas of the elastic vessels such as the aorta and the pulmonary artery or vein are undifferentiated sarcomas, while leiomyosarcomas predominate in the muscular arteries and great veins such as the inferior vena cava. Pulmonary vessel sarcomas are rare and show no characteristic symptoms, even though the thromboembolic events are the most severe events, and a subsequently delayed diagnosis may contribute to a fulminant prognosis. Recent advances in imaging modalities and accumulated clinical experience have made it possible to preoperatively diagnose these tumors. Most pulmonary vessel sarcomas have been reported as single case reports and there have only been a few radiologic review articles. Here, we review pulmonary artery and vein sarcomas with their clinicopathologic features. MATERIALS AND METHODS

Pulmonary Vascular Sarcomas: Clinicopathologic Analysis of 14 Cases

Background/Aims Socioecomomic factor is an important determinant of access to healthcare and is one of the potential causes of disparities in esophageal cancer care outcomes. The aim of the study was to clarify the association between National health Insurance status (health insurance vs. medicare) as a socioeconomic factor and survival of patients with esophageal cancer who underwent surgical resection. Methods Among the 66 patients who underwent surgical resection for esophageal cancer between January 2006 and December 2017, 17 patients (25.8%) were in the medicare group. The data were analyzed to identify clinical manifestations and to compare surgical and oncologic outcomes between the groups. Results There was no significant difference in the distribution of sex (p=0.13), age (p=0.24), and pathologic stage (p=0.61) between the groups. The length of median hospital stay was significantly shorter in the healthy insurance group (18 days vs. 25 days, p=0.04). In the medicare group, postoperative mortality rates and incidence of postoperative complication were non-significantly higher(11.8% vs. 6.1%, p=0.45, 64.7% vs. 46.7%, p=0.21, respectively). However, pulmonary complication rates, including pneumonia, acute respiratory distress syndorme, and prolonged air leakage was significantly higher in the medicare group (47.1% vs. 18.4%, p=0.02). Five-year disease free survival rate was not different between the two groups (61.0% vs. 54.5%, p=0.68); the 5-year overall survival rate was significantly lower in the medicare group (27.7% vs. 53.7%, p=0.03). Conclusions The medicare status of National health insurance could have a negative influence on the overall survival in patients with esophageal cancer who underwent surgery.
