Rethinking the role of clinical imaging.
(ELIFE SCIENCES PUBLICATIONS LTD, 2017-09-06)Radiomics has the potential to improve the management of cancer patients, but further research is required before it can be adopted into routine clinical practice. -
Partial-breast radiotherapy after breast conservation surgery for patients with early breast cancer (UK IMPORT LOW trial): 5-year results from a multicentre, randomised, controlled, phase 3, non-inferiority trial.
(ELSEVIER SCIENCE INC, 2017-09-09)BACKGROUND: Local cancer relapse risk after breast conservation surgery followed by radiotherapy has fallen sharply in many countries, and is influenced by patient age and clinicopathological factors. We hypothesise that ... -
Appraising the relevance of DNA copy number loss and gain in prostate cancer using whole genome DNA sequence data.
(PUBLIC LIBRARY SCIENCE, 2017-09-25)A variety of models have been proposed to explain regions of recurrent somatic copy number alteration (SCNA) in human cancer. Our study employs Whole Genome DNA Sequence (WGS) data from tumor samples (n = 103) to comprehensively ... -
The potential of <sup>223</sup>Ra and <sup>18</sup>F-fluoride imaging to predict bone lesion response to treatment with <sup>223</sup>Ra-dichloride in castration-resistant prostate cancer.
(2017-10)Purpose The aims of this study were to calculate bone lesion absorbed doses resulting from a weight-based administration of 223 Ra-dichloride, to assess the relationship between those doses and corresponding 18 F-fluoride ... -
T2-Weighted 4D Magnetic Resonance Imaging for Application in Magnetic Resonance-Guided Radiotherapy Treatment Planning.
(LIPPINCOTT WILLIAMS & WILKINS, 2017-10-01)OBJECTIVES: The aim of this study was to develop and verify a method to obtain good temporal resolution T2-weighted 4-dimensional (4D-T2w) magnetic resonance imaging (MRI) by using motion information from T1-weighted 4D ... -
Upfront Docetaxel in the Post-STAMPEDE World: Lessons from an Early Evaluation of Non-trial Usage in Hormone-Sensitive Prostate Cancer.

Motion monitoring during a course of lung radiotherapy with anchored electromagnetic transponders : Quantification of inter- and intrafraction motion and variability of relative transponder positions.
(SPRINGER HEIDELBERG, 2017-10-01)PURPOSE: Anchored electromagnetic transponders for tumor motion monitoring during lung radiotherapy were clinically evaluated. First, intrafractional motion patterns were analyzed as well as their interfractional variations. ... -
The effect of parotid gland-sparing intensity-modulated radiotherapy on salivary composition, flow rate and xerostomia measures.
(WILEY, 2017-10-01)OBJECTIVES: To describe parotid gland (PG) saliva organic and inorganic composition and flow rate changes, after curative intensity-modulated radiotherapy (IMRT) for head and neck cancer (HNC), and analyse the relationship ... -
Effect on Overall Survival of Locoregional Treatment in a Cohort of De Novo Metastatic Prostate Cancer Patients: A Single Institution Retrospective Analysis From the Royal Marsden Hospital.
(CIG MEDIA GROUP, LP, 2017-10-01)BACKGROUND: The optimal management of the primary tumor in metastatic at diagnosis (M1) prostate cancer (PCa) patients is not yet established. We retrospectively evaluated the effect of locoregional treatment (LRT) on ... -
Integrated Molecular Meta-Analysis of 1,000 Pediatric High-Grade and Diffuse Intrinsic Pontine Glioma.
(CELL PRESS, 2017-10-09)We collated data from 157 unpublished cases of pediatric high-grade glioma and diffuse intrinsic pontine glioma and 20 publicly available datasets in an integrated analysis of >1,000 cases. We identified co-segregating ... -
Gold nanorod reshaping in vitro and in vivo using a continuous wave laser.
(PUBLIC LIBRARY SCIENCE, 2017-10-18)Gold nanorods (GNRs) are increasingly being investigated for cancer theranostics as they possess features which lend themselves in equal measures as contrast agents and catalysts for photothermal therapy. Their optical ... -
A data-driven statistical model that estimates measurement uncertainty improves interpretation of ADC reproducibility: a multi-site study of liver metastases.
(NATURE PORTFOLIO, 2017-10-26)Apparent Diffusion Coefficient (ADC) is a potential quantitative imaging biomarker for tumour cell density and is widely used to detect early treatment changes in cancer therapy. We propose a strategy to improve confidence ... -
