DNA Repair in Prostate Cancer: Biology and Clinical Implications.
(ELSEVIER SCIENCE BV, 2017-03-01)CONTEXT: For more precise, personalized care in prostate cancer (PC), a new classification based on molecular features relevant for prognostication and treatment stratification is needed. Genomic aberrations in the DNA ... -
The Added Value of Circulating Tumor Cell Enumeration to Standard Markers in Assessing Prognosis in a Metastatic Castration-Resistant Prostate Cancer Population.
(AMER ASSOC CANCER RESEARCH, 2017-04-15)Purpose: Metastatic castration-resistant prostate cancer (mCRPC) is a heterogeneous disease for which better prognostic models for survival are needed. We examined the added value of circulating tumor cell (CTC) enumeration ... -
Analytical Validation and Clinical Qualification of a New Immunohistochemical Assay for Androgen Receptor Splice Variant-7 Protein Expression in Metastatic Castration-resistant Prostate Cancer.
(ELSEVIER SCIENCE BV, 2016-10-01)BACKGROUND: The androgen receptor splice variant-7 (AR-V7) has been implicated in the development of castration-resistant prostate cancer (CRPC) and resistance to abiraterone and enzalutamide. OBJECTIVE: To develop a ... -
Impact of fusion gene status versus histology on risk-stratification for rhabdomyosarcoma: Retrospective analyses of patients on UK trials.
(WILEY, 2017-07-01)BACKGROUND: Long-term toxicities from current treatments are a major issue in paediatric cancer. Previous studies, including our own, have shown prognostic value for the presence of PAX3/7-FOXO1 fusion genes in rhabdomyosarcoma ... -
Extended T2-IVIM model for correction of TE dependence of pseudo-diffusion volume fraction in clinical diffusion-weighted magnetic resonance imaging.
(IOP PUBLISHING LTD, 2016-12-21)The bi-exponential intravoxel-incoherent-motion (IVIM) model for diffusion-weighted MRI (DWI) fails to account for differential T 2 s in the model compartments, resulting in overestimation of pseudodiffusion fraction f. ... -
MicroRNA and gene co-expression networks characterize biological and clinical behavior of rhabdomyosarcomas.
(ELSEVIER IRELAND LTD, 2017-01-28)Rhabdomyosarcomas (RMS) in children and adolescents are heterogeneous sarcomas broadly defined by skeletal muscle features and the presence/absence of PAX3/7-FOXO1 fusion genes. MicroRNAs are small non-coding RNAs that ... -
Effect of population breast screening on breast cancer mortality up to 2005 in England and Wales: an individual-level cohort study.
(SPRINGERNATURE, 2017-01-17)BACKGROUND: Population breast screening has been implemented in the UK for over 25 years, but the size of benefit attributable to such programmes remains controversial. We have conducted the first individual-based cohort ... -
Recurrent MET fusion genes represent a drug target in pediatric glioblastoma.
(NATURE PORTFOLIO, 2016-11-01)Pediatric glioblastoma is one of the most common and most deadly brain tumors in childhood. Using an integrative genetic analysis of 53 pediatric glioblastomas and five in vitro model systems, we identified previously ... -
Variation at 2q35 (PNKD and TMBIM1) influences colorectal cancer risk and identifies a pleiotropic effect with inflammatory bowel disease.
(OXFORD UNIV PRESS, 2016-06-01)To identify new risk loci for colorectal cancer (CRC), we conducted a meta-analysis of seven genome-wide association studies (GWAS) with independent replication, totalling 13 656 CRC cases and 21 667 controls of European ... -
Multiple myeloma risk variant at 7p15.3 creates an IRF4-binding site and interferes with CDCA7L expression.
(NATURE PUBLISHING GROUP, 2016-11-24)Genome-wide association studies have identified several risk loci for multiple myeloma (MM); however, the mechanisms by which they influence MM are unknown. Here by using genetic association data and functional characterization, ... -
Phase III, Double-Blind, Randomized Trial That Compared Maintenance Lapatinib Versus Placebo After First-Line Chemotherapy in Patients With Human Epidermal Growth Factor Receptor 1/2-Positive Metastatic Bladder Cancer.
(AMER SOC CLINICAL ONCOLOGY, 2017-01-01)Purpose To establish whether maintenance lapatinib after first-line chemotherapy is beneficial in human epidermal growth factor receptor (HER) 1/HER2-positive metastatic urothelial bladder cancer (UBC). Methods Patients ... -
Biopsy proportion of tumour predicts pathological tumour response and benefit from chemotherapy in resectable oesophageal carcinoma: results from the UK MRC OE02 trial.
(2016-11)Background Neoadjuvant chemotherapy followed by surgery is the standard of care for UK patients with locally advanced resectable oesophageal carcinoma (OeC). However, not all patients benefit from multimodal treatment and ... -
Determining the chemical exchange saturation transfer (CEST) behavior of citrate and spermine under in vivo conditions.
(WILEY-BLACKWELL, 2016-09-01)PURPOSE: To estimate the exchange rates of labile (1) H in citrate and spermine, metabolites present in prostatic secretions, to predict the size of the citrate and spermine CEST effects in vivo. METHODS: CEST z-spectra ... -

(RADIOLOGICAL SOC NORTH AMERICA, 2014-06-01)PURPOSE: To determine the feasibility of whole-body diffusion-weighted (DW) magnetic resonance (MR) imaging for assessment of treatment response in myeloma. MATERIALS AND METHODS: This prospective single-institution study ... -
RET Functions as a Dual-Specificity Kinase that Requires Allosteric Inputs from Juxtamembrane Elements.
