A preclinical microbeam facility with a conventional x-ray tube.
(2016-12)Purpose Microbeam radiation therapy is an innovative treatment approach in radiation therapy that uses arrays of a few tens of micrometer wide and a few hundreds of micrometer spaced planar x-ray beams as treatment fields. ... -
Baseline results from the UK SIGNIFY study: a whole-body MRI screening study in TP53 mutation carriers and matched controls.
(SPRINGER, 2017-07-01)In the United Kingdom, current screening guidelines for TP53 germline mutation carriers solely recommends annual breast MRI, despite the wide spectrum of malignancies typically seen in this group. This study sought to ... -
Repeatability of derived parameters from histograms following non-Gaussian diffusion modelling of diffusion-weighted imaging in a paediatric oncological cohort.
(SPRINGER, 2017-01-01)OBJECTIVES: To examine repeatability of parameters derived from non-Gaussian diffusion models in data acquired in children with solid tumours. METHODS: Paediatric patients (<16 years, n = 17) were scanned twice, 24 h apart, ... -
Endovaginal magnetic resonance imaging of stage 1A/1B cervical cancer with A T2- and diffusion-weighted magnetic resonance technique: effect of lesion size and previous cone biopsy on tumor detectability.
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011-03-01)OBJECTIVE: To evaluate the effects of previous cone biopsy and lesion size on detectability of stage 1a/1b cervical cancer using endovaginal T2- and diffusion-weighted magnetic resonance imaging. METHODS: One hundred and ... -
Initial experience of the BREAST-Q breast-conserving therapy module.
(SPRINGER, 2016-11-01)PURPOSE: The most recently developed module of the BREAST-Q, a validated patient outcome measure, is for patients who have undergone breast-conserving therapy (BCT) for cancer. This aim of this study was to assess patient ... -
A randomized control trial evaluating fluorescent ink versus dark ink tattoos for breast radiotherapy.
(BRITISH INST RADIOLOGY, 2016-12-01)OBJECTIVE: The purpose of this UK study was to evaluate interfraction reproducibility and body image score when using ultraviolet (UV) tattoos (not visible in ambient lighting) for external references during breast/chest ... -
Mean heart dose variation over a course of breath-holding breast cancer radiotherapy.
(2016-11)Objective The purpose of the work was to estimate the dose received by the heart throughout a course of breath-holding breast radiotherapy.Methods 113 cone-beam CT (CBCT) scans were acquired for 20 patients treated within ... -
Immunogenicity of self tumor associated proteins is enhanced through protein truncation.
(CELL PRESS, 2016-12-07)We showed previously that therapy with Vesicular Stomatitis Virus (VSV) expressing tumor-associated proteins eradicates established tumors. We show here that when cellular cDNA were cloned into VSV which retained their own ... -
Rare disruptive mutations in ciliary function genes contribute to testicular cancer susceptibility.
(NATURE PUBLISHING GROUP, 2016-12-20)Testicular germ cell tumour (TGCT) is the most common cancer in young men. Here we sought to identify risk factors for TGCT by performing whole-exome sequencing on 328 TGCT cases from 153 families, 634 sporadic TGCT cases ... -
An orally bioavailable Chk1 inhibitor, CCT244747, sensitizes bladder and head and neck cancer cell lines to radiation.
(2017-03)Purpose Chk1 inhibition increases cell sensitivity to both chemotherapy and radiotherapy in several tumour types and is, therefore, a promising anti-cancer approach. Although several Chk1 inhibitors have been developed, ... -
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. ... -
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 ... -
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 ... -
Whole-body diffusion-weighted MR imaging for assessment of treatment response in myeloma.
(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 ... -
A novel approach to evaluate spatial resolution of MRI clinical images for optimization and standardization of breast screening protocols.
(AMER ASSOC PHYSICISTS MEDICINE AMER INST PHYSICS, 2016-12-01)PURPOSE: Stringent quality assurance is required in MRI breast screening to ensure that different scanners and imaging protocols reach similar diagnostic performance. The authors propose a methodology, based on power ... -
Blood transfusion during radical chemo-radiotherapy does not reduce tumour hypoxia in squamous cell cancer of the head and neck.
(NATURE PUBLISHING GROUP, 2017-01-03)BACKGROUND: Patients with head and neck squamous cell carcinoma (HNSCC) undergoing radical chemo-radiation (CRT) frequently receive transfusion with packed red cells (PRCT) during radiotherapy on the basis that PRCT increases ... -
