A cohort of 109 patients with primary transitional cell carcinomas, stages T2-T3, grade 2 or higher, was identified and further divided into two groups based on lymphatic metastasis at the time of cystectomy (n = 57 cases) or absence of detectable metastatic disease over a minimum of 5 years of follow-up after cystectomy (n = 52). Blocks corresponding to the primary tumor lesions were sectioned...
BACKGROUND Recent data suggest that noninvasive liver fibrosis indexes could be useful for predicting esophageal varices (EV) in cirrhotic patients. However, thus far, the diagnostic efficacy of these indexes in predicting portal hypertension (PH) in cirrhotic patients has been poorly evaluated. AIMS To evaluate the diagnostic efficacy of noninvasive liver fibrosis indexes in the diagnosis of...
AIM To identify simple and sensitive markers for postoperative complications after gastrectomy, the predictive values were compared among candidate preoperative factors. METHODS Three-hundred and twelve patients with previously untreated clinical T2-4 gastric cancer who underwent a D2 standard gastrectomy (distal gastrectomy or total gastrectomy) were included in the analysis. Correlations be...
UNLABELLED Nonanastomotic biliary strictures (NAS) remain a frequent complication after orthotopic liver transplantation (OLT). The aim of this study was to evaluate whether magnetic resonance cholangiopancreatography (MRCP) could be used to detect NAS and to grade the severity of biliary strictures. METHODS In total, 58 patients after OLT from 2 Dutch transplantation centers in whom endoscop...
BACKGROUND Dabrafenib, an inhibitor of mutated BRAF, has clinical activity with a manageable safety profile in studies of phase 1 and 2 in patients with BRAF(V600)-mutated metastatic melanoma. We studied the efficacy of dabrafenib in patients with BRAF(V600E)-mutated metastatic melanoma. METHODS We enrolled patients in this open-label phase 3 trial between Dec 23, 2010, and Sept 1, 2011. This...
Objective Although 18-fluorine fluorodeoxyglucose positron emission tomography (18F-FDG PET) is thought to be useful for predicting the histological grade of thymic epithelial tumors (TETs), it remains controversial. To date, just a few of many previous studies have included only resected cases. Therefore, we investigated 18F-FDG PET findings only in patients with resected TETs. Patients and ...
BACKGROUND AND PURPOSE Prognosis in glioma depends strongly on tumor grade and proliferation. In this prospective study of patients with untreated primary cerebral gliomas, we investigated whether amide proton transfer-weighted imaging could reveal tumor proliferation and reliably distinguish low-grade from high-grade gliomas compared with Ki-67 expression and proton MR spectroscopy imaging. ...
