(SPRINGER, 2019-01-07)BACKGROUND: The aim of this work was to characterise the attenuation properties of 3D-printed tungsten and to assess the feasibility for its use in gamma camera collimator manufacture. METHOD: 3D-printed tungsten disks ... -
Calculation of absorbed dose in radiotherapy by solution of the linear Boltzmann transport equations.
(2019-01-10)Over the last decade, dose calculations which solve the linear Boltzmann transport equations have been introduced into clinical practice and are now in widespread use. However, knowledge in the radiotherapy community ... -
Pembrolizumab versus methotrexate, docetaxel, or cetuximab for recurrent or metastatic head-and-neck squamous cell carcinoma (KEYNOTE-040): a randomised, open-label, phase 3 study.
(ELSEVIER SCIENCE INC, 2019-01-12)BACKGROUND: There are few effective treatment options for patients with recurrent or metastatic head-and-neck squamous cell carcinoma. Pembrolizumab showed antitumour activity and manageable toxicity in early-phase trials. ... -
Patritumab with Cetuximab plus Platinum-Containing Therapy in Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck: An Open-Label, Phase Ib Study.
(AMER ASSOC CANCER RESEARCH, 2019-01-15)PURPOSE: Patritumab plus cetuximab with platinum as first-line therapy for patients with recurrent and/or metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN) was evaluated for safety and to determine the ... -
Shared heritability and functional enrichment across six solid cancers.
(NATURE PORTFOLIO, 2019-01-25)Quantifying the genetic correlation between cancers can provide important insights into the mechanisms driving cancer etiology. Using genome-wide association study summary statistics across six cancer types based on a total ... -
Patient-Reported Outcomes Over 5 Years After Whole- or Partial-Breast Radiotherapy: Longitudinal Analysis of the IMPORT LOW (CRUK/06/003) Phase III Randomized Controlled Trial.
(2019-02)Purpose IMPORT LOW demonstrated noninferiority of partial-breast and reduced-dose radiotherapy versus whole-breast radiotherapy for local relapse and similar or reduced toxicity at 5 years. Comprehensive patient-reported ... -
Managing Nonmetastatic Castration-resistant Prostate Cancer.
(ELSEVIER, 2019-02-01)CONTEXT: Patients with nonmetastatic castration-resistant prostate cancer (nmCRPC) have rising prostate-specific antigen (PSA) and castrate testosterone levels, with no radiological findings of metastatic disease on computed ... -
A risk-based approach to identifying oligometastatic disease on imaging.
(WILEY, 2019-02-01)Recognition of <3 metastases in <2 organs, particularly in cancers with a known predisposition to oligometastatic disease (OMD) (colorectal, prostate, renal, sarcoma and lung), offers the opportunity to focally treat the ... -
Psychosocial impact of undergoing prostate cancer screening for men with BRCA1 or BRCA2 mutations.
(WILEY, 2019-02-01)OBJECTIVES: To report the baseline results of a longitudinal psychosocial study that forms part of the IMPACT study, a multi-national investigation of targeted prostate cancer (PCa) screening among men with a known pathogenic ... -

(AMER SOC CLINICAL ONCOLOGY, 2019-02-01)PURPOSE: IMPORT LOW demonstrated noninferiority of partial-breast and reduced-dose radiotherapy versus whole-breast radiotherapy for local relapse and similar or reduced toxicity at 5 years. Comprehensive patient-reported ... -
Comparison of Imaging Changes and Pain Responses in Patients with Intra- or Extraosseous Bone Metastases Treated Palliatively with Magnetic Resonance-Guided High-Intensity-Focused Ultrasound.
(ELSEVIER SCIENCE INC, 2019-02-21)PURPOSE: This study compared changes in imaging and in pain relief between patients with intraosseous, as opposed to extraosseous bone metastases. Both groups were treated palliatively with magnetic resonance-guided ... -
Quantitative photoacoustic imaging study of tumours in vivo: Baseline variations in quantitative measurements.
(ELSEVIER GMBH, 2019-03-01)Photoacoustic imaging (PAI) provides information on haemoglobin levels and blood oxygenation (sO2). To facilitate assessment of the variability in sO2 and haemoglobin in tumours, for example in response to therapies, the ... -
SHH pathway inhibition is protumourigenic in adamantinomatous craniopharyngioma.
(BIOSCIENTIFICA LTD, 2019-03-01)Pharmacological inhibition of the sonic hedgehog (SHH) pathway can be beneficial against certain cancers but detrimental in others. Adamantinomatous craniopharyngioma (ACP) is a relevant pituitary tumour, affecting children ... -
