To clarify whether pre-operative transcatheter arterial embolization (TAE) improves survival after hepatectomy, a prospective randomized comparative study was done. Of a total of 115 registered patients having solitary hepatocellular carcinoma (HCC) 2 to 5 cm in diameter, 18 (15.7%) were excluded after randomization. As a result, 97 patients were chosen as(More)
PURPOSE To determine the factors that may be used to predict outcome of stent placement in patients with malignancies obstructing the superior or inferior vena cava. MATERIALS AND METHODS Gianturco stents were placed in 39 patients with malignant obstruction of the superior (n = 16) or inferior (n = 23) vena cava. Thirteen patients with obstruction of the(More)
Gianturco expandable metallic stents were used for treating six patients with inferior vena cava (IVC) obstruction due to compression by large hepatic tumors and three patients with idiopathic obstruction of the hepatic IVC and Budd-Chiari syndrome who showed reocclusion or stenosis 3-21 months after previously performed percutaneous transluminal(More)
PURPOSE Stereotactic radiotherapy (SRT) is highly effective for brain metastases from non-small-cell lung cancers (NSCLCs). As such, primary lesions of NSCLC may also be treated effectively by similar focal high-dose SRT. METHODS AND MATERIALS Between October 1994 and June 1999, 50 patients with pathologically proven T1-2N0 M0 NSCLC were treated by(More)
A series of gal promoter mutants has been used to compare the in vitro selectivities of the two forms of Escherichia coli RNA polymerase, E sigma 38 and E sigma 70. In the absence of the CRP-cAMP complex, E sigma 38 shows a strong preference for the ga/P1 promoter, whereas E sigma 70 preferentially initiates transcription from the ga/P2 promoter. E sigma 38(More)
Transcription in vitro of two osmoregulated promoters, for the Escherichia coli osmB and osmY genes, was analysed using two species of RNA polymerase holoenzyme reconstituted from purified core enzyme and either sigma D (sigma 70, the major sigma in exponentially growing cells) or sigma S (sigma 38, the principal sigma at stationary growth phase). Under(More)
CONTEXT Recent studies have demonstrated the potential cost-effectiveness of using 2-fluoro-2-D-[(18)F]fluorodeoxyglucose (FDG) positron emission tomography (PET) in the management of non-small cell lung carcinoma (NSCLC), but because of differences in health-care systems, those findings may not hold true in a Japanese hospital. OBJECTIVE To assess the(More)
OBJECTIVE We hypothesized that CT with arterial portography (CTAP) might depict tumors undetected by CT with infusion hepatic arteriography (CTIHA), and the converse. Accordingly, we compared the detection rate of malignant tumors using CTAP, CTIHA, and simultaneous use of both techniques to determine whether CTIHA can be used to distinguish malignant from(More)
Parenchymal perfusion of the normal human pancreas using dynamic computed tomography (CT) was evaluated and correlated with patient demographic characteristics. The results of 23 patients (10 men and 13 women; age range, 25-71 years) who underwent enhanced CT of the upper abdomen and perfusion measurement were retrospectively reviewed. They had no evidence(More)
Correlation of magnetic resonance (MR) imaging findings and those at pathologic evaluation was attempted in six cases of solid and papillary epithelial neoplasm of the pancreas. All patients were female, and the mean patient age was 26 years (range, 13-73 years). On T1-weighted spin-echo images, tumors were well demarcated, and areas of high signal(More)
