Daily adaptive radiotherapy for patients with prostate cancer using a high field MR-linac: Initial clinical experiences and assessment of delivered doses compared to a C-arm linac.
(ELSEVIER IRELAND LTD, 2020-07-01)INTRODUCTION: MR-guided adapted radiotherapy (MRgART) using a high field MR-linac has recently become available. We report the estimated delivered fractional dose of the first five prostate cancer patients treated at our ... -
Extrameningeal solitary fibrous tumors-surgery alone or surgery plus perioperative radiotherapy: A retrospective study from the global solitary fibrous tumor initiative in collaboration with the Sarcoma Patients EuroNet.
(WILEY, 2020-07-01)BACKGROUND: Solitary fibrous tumor (SFT) is a rare mesenchymal malignancy. Although surgery is potentially curative, the local relapse risk is high after marginal resections. Given the lack of prospective clinical trial ... -
A treatment planning study of combined carbon ion-beam plus photon intensity-modulated radiotherapy.
(ELSEVIER, 2020-07-01)BACKGROUND AND PURPOSE: Combined photon intensity-modulated radiotherapy (IMRT) and sequential dose-escalated carbon ion beam therapy (IBT) is a technically advanced treatment option for head and neck malignancies. We ... -
Evaluation of MRI-derived surrogate signals to model respiratory motion.
(IOP PUBLISHING LTD, 2020-07-01)An MR-Linac can provide motion information of tumour and organs-at-risk before, during, and after beam delivery. However, MR imaging cannot provide real-time high-quality volumetric images which capture breath-to-breath ... -
The impact of restricted length of treatment field and anthropometric factors on selection of head and neck cancer patients for treatment on the MR-Linac.
(BRITISH INST RADIOLOGY, 2020-07-01)OBJECTIVE: This study investigates the impact of a restricted craniocaudal (CC) field length of <20 cm on the selection of head and neck cancer (HNC) patients who can be treated on the MR-Linac using a single isocentre ... -
A rapid review of evidence and recommendations from the SIOPE radiation oncology working group to help mitigate for reduced paediatric radiotherapy capacity during the COVID-19 pandemic or other crises.
(ELSEVIER IRELAND LTD, 2020-07-01)OBJECTIVE: To derive evidence-based recommendations for the optimal utilisation of resources during unexpected shortage of radiotherapy capacity. METHODS AND MATERIALS: We have undertaken a rapid review of published ... -
Assessment of polygenic architecture and risk prediction based on common variants across fourteen cancers.
(NATURE PORTFOLIO, 2020-07-03)Genome-wide association studies (GWAS) have led to the identification of hundreds of susceptibility loci across cancers, but the impact of further studies remains uncertain. Here we analyse summary-level data from GWAS of ... -
Inter-observer agreement of baseline whole body MRI in multiple myeloma.
(BMC, 2020-07-14)BACKGROUND: Whole body magnetic resonance imaging (MRI) is now incorporated into international guidance for imaging patients with multiple myeloma. The aim of this study was to investigate inter-observer agreement of triple ... -
Increased Dose to Organs in Urinary Tract Associates With Measures of Genitourinary Toxicity in Pooled Voxel-Based Analysis of 3 Randomized Phase III Trials.
(FRONTIERS MEDIA SA, 2020-07-22)Purpose: Dose information from organ sub-regions has been shown to be more predictive of genitourinary toxicity than whole organ dose volume histogram information. This study aimed to identify anatomically-localized regions ... -
Relationship of Cisplatin-Related Adverse Health Outcomes With Disability and Unemployment Among Testicular Cancer Survivors.
(OXFORD UNIV PRESS, 2020-08-01)BACKGROUND: Few data exist on the relationship of cisplatin-related adverse health outcomes (AHOs) with disability, unemployment, and self-reported health (SRH) among testicular cancer survivors (TCS). METHODS: A total of ... -
Improving 3D ultrasound prostate localisation in radiotherapy through increased automation of interfraction matching.
(ELSEVIER IRELAND LTD, 2020-08-01)BACKGROUND AND PURPOSE: Daily image guidance is standard care for prostate radiotherapy. Innovations which improve the accuracy and efficiency of ultrasound guidance are needed, particularly with respect to reducing ... -
Radiomics as a personalized medicine tool in lung cancer: Separating the hope from the hype.
(ELSEVIER IRELAND LTD, 2020-08-01)Radiomics has become a popular image analysis method in the last few years. Its key hypothesis is that medical images harbor biological, prognostic and predictive information that is not revealed upon visual inspection. ... -
The Automated Bone Scan Index as a Predictor of Response to Prostate Radiotherapy in Men with Newly Diagnosed Metastatic Prostate Cancer: An Exploratory Analysis of STAMPEDE's "M1|RT Comparison".
(ELSEVIER, 2020-08-01)BACKGROUND: Prostate radiotherapy (RT) is a first-line option for newly diagnosed men with low-burden metastatic prostate cancer. The current criterion to define this clinical state is based on manual bone metastasis counts, ... -
The role of spread through air spaces (STAS) in lung adenocarcinoma prognosis and therapeutic decision making.
(ELSEVIER IRELAND LTD, 2020-08-01)Spread through air spaces (STAS) was included as a novel pattern of invasion in lung adenocarcinoma by the World Health Organization in 2015. Since then, multiple studies have investigated the association of STAS with ... -
An integrative multi-omics analysis to identify candidate DNA methylation biomarkers related to prostate cancer risk.
(NATURE PUBLISHING GROUP, 2020-08-06)It remains elusive whether some of the associations identified in genome-wide association studies of prostate cancer (PrCa) may be due to regulatory effects of genetic variants on CpG sites, which may further influence ... -
