PURPOSE To provide an overview of current clinical results of irreversible electroporation (IRE), a novel, nonthermal tumor ablation technique that uses electric pulses to induce cell death, while preserving structural integrity of bile ducts and vessels. METHODS All in-human literature on IRE reporting safety or efficacy or both was included. All adverse(More)
Tumor cells may display a multidrug resistant phenotype by overexpression of ATP-binding cassette transporters such as multidrug resistance (MDRI) P-glycoprotein, multidrug resistance protein 1 (MRP1), and breast cancer resistance protein (BCRP). The presence of BCRP has thus far been reported solely using mRNA data. In this study, we describe a(More)
Hypoxia has clinically been associated with resistance to chemotherapy. The aim of this study was to investigate whether hypoxia induces resistance to doxorubicin and mitoxantrone, two common drugs in cancer treatment, in MCF-7 breast cancer cells, and SW1573 non-small lung cancer cells. In addition, the role of drug transporters P-gp, BCRP and MRP1 was(More)
OBJECTIVES To determine and compare the diagnostic performance of stress myocardial perfusion imaging (MPI) for the diagnosis of obstructive coronary artery disease (CAD), using conventional coronary angiography (CCA) as the reference standard. METHODS We searched Medline and Embase for literature that evaluated stress MPI for the diagnosis of obstructive(More)
BACKGROUND A recent study from our laboratory showed that induction of the multidrug resistance related drug efflux pump ABCG2 contributed to acquired resistance of human T cells to the disease modifying antirheumatic drug (DMARD) sulfasalazine (SSZ). OBJECTIVES To investigate the duration of SSZ resistance and ABCG2 expression after withdrawal of SSZ and(More)
Stunted growth is a serious problem for children with chronic renal failure (CRF) despite normal endogenous growth hormone secretion and normal or elevated plasma concentrations of insulin-like growth factors (IGF) I and II. Biosynthetic growth hormone (GH) was given to 20 prepubertal children (eleven boys, nine girls; mean age 9.5 years, range 4-16) with(More)
Growth failure is a psychosocial problem for many patients who have undergone renal transplantation. 18 adolescents (mean age 15.6, range 11.3-19.5) with severe growth retardation after renal transplantation were treated with biosynthetic growth hormone (GH) for 2 years. All received prednisone, administered daily or on alternate days, with azathioprine(More)
BACKGROUND Retinoblastoma is a pediatric eye cancer associated with RB1 loss or MYCN amplification (RB1 (+/+) MYCN(A) ). There are controversies concerning the existence of molecular subtypes within RB1(-/-) retinoblastoma. To test whether these molecular subtypes exist, we performed molecular profiling. METHODS Genome-wide mRNA expression profiling was(More)
PURPOSE To retrospectively analyse the safety and efficacy of radiofrequency ablation (RFA) versus microwave ablation (MWA) in the treatment of unresectable colorectal liver metastases (CRLM) in proximity to large vessels and/or major bile ducts. METHOD AND MATERIALS A database search was performed to include patients with unresectable histologically(More)
BACKGROUND While RB1 loss initiates retinoblastoma development, additional somatic copy number alterations (SCNAs) can drive tumor progression. Although SCNAs have been identified with good concordance between studies at a cytoband resolution, accurate identification of single genes for all recurrent SCNAs is still challenging. This study presents a(More)
