Typical radiologic findings of a pulmonary metastasis include multiple round variable-sized nodules and diffuse thickening of interstitium. In daily practice, however, atypical radiologic features of metastases are often encountered that make distinction of metastases from other nonmalignant pulmonary diseases difficult. A detailed knowledge of the atypical(More)
Recently, endoscopic submucosal dissection has been carefully applied in early gastric cancer (EGC) with undifferentiated type. However, there are no individual guidelines for endoscopic treatment of EGCs with poorly differentiated tubular adenocarcinoma or signet ring cell carcinoma. The aim of this study was to investigate and compare the(More)
BACKGROUND AND AIM Primary hepatic neuroendocrine carcinomas (PHNECs) are extremely rare, with only about 150 cases having been reported in the English-language literature. Because of the rarity of PHNECs, its clinical features and treatment outcomes are not well understood. Here, we report our experiences with PHNECs. METHODS We identified patients(More)
PURPOSE To investigate the use of pretreatment carbohydrate antigen (CA) 19-9 and carcinoembryonic antigen (CEA) as prognostic factors to determine survival in pancreatic adenocarcinoma. MATERIALS AND METHODS A retrospective review of the medical records of patients who were diagnosed with pancreatic adenocarcinoma and received surgery, chemoradiotherapy(More)
Hemolytic uremic syndrome (HUS) is a rare thrombotic complication characterized by a triad of microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure. HUS may be caused by several different conditions, including infection, malignancy, and chemotherapeutic agents, such as mitomycin, cisplatin, and most recently, gemcitabine. The outcome(More)
OBJECTIVE To compare the clinical and radiographic features of pulmonary tuberculosis (PTB) and non-tuberculous mycobacteria (NTM) lung disease in patients with acid-fast bacilli (AFB) positive sputum specimens. DESIGN The initial clinical and radiographic features of 229 PTB patients were compared with those of 70 patients with NTM lung disease. The most(More)
Second-line chemotherapy in patients with gemcitabine-refractory advanced pancreatic cancer has shown disappointing survival outcomes due to rapid disease progression and performance deterioration. The aim of this phase II trial was to evaluate the efficacy and safety of adoptive immunotherapy using ex vivo-expanded, cytokine-induced killer (CIK) cells in(More)
BACKGROUND AND STUDY AIMS Rectal nonsteroidal anti-inflammatory drugs have been shown to reduce the incidence of postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). The aim of this study was to determine whether intramuscular diclofenac reduces the risk of PEP. PATIENTS AND METHODS Patients who underwent ERCP were randomized to(More)
UNLABELLED The purpose of this study was to examine the direct effects of propofol on ischemia-reperfusion injury using an isolated Langendorff rat heart preparation. Hearts were perfused with Krebs-Henseleit (K-H) solution (control); intralipid; or 10, 30, and 100 microM propofol. Hearts were rendered globally ischemic for 25 min, then reperfusion was(More)
Hepatolithiasis is a known risk factor for cholangiocarcinoma (CC). Due to the high risk of complications that accompany endoscopic and surgical stone removal, it is often difficult to decide whether it is beneficial to remove intrahepatic ductal stones. We conducted a case–control study to determine the risk of developing CC and the benefit of stone(More)
