Adverse Health Outcomes in Relationship to Hypogonadism After Chemotherapy: A Multicenter Study of Testicular Cancer Survivors.
(HARBORSIDE PRESS, 2019-05-01)BACKGROUND: This study examined the prevalence of hypogonadism, its clinical and genetic risk factors, and its relationship to adverse health outcomes (AHOs) in North American testicular cancer survivors (TCS) after modern ... -
Homeobox B13 G84E Mutation and Prostate Cancer Risk.
(ELSEVIER, 2019-05-01)BACKGROUND: The homeobox B13 (HOXB13) G84E mutation has been recommended for use in genetic counselling for prostate cancer (PCa), but the magnitude of PCa risk conferred by this mutation is uncertain. OBJECTIVE: To obtain ... -
Realizing the potential of magnetic resonance image guided radiotherapy in gynaecological and rectal cancer.
(BRITISH INST RADIOLOGY, 2019-05-14)CT-based radiotherapy workflow is limited by poor soft tissue definition in the pelvis and reliance on rigid registration methods. Current image-guided radiotherapy and adaptive radiotherapy models therefore have limited ... -
A novel amplitude binning strategy to handle irregular breathing during 4DMRI acquisition: improved imaging for radiotherapy purposes.
(BMC, 2019-05-14)BACKGROUND: For radiotherapy of abdominal cancer, four-dimensional magnetic resonance imaging (4DMRI) is desirable for tumor definition and the assessment of tumor and organ motion. However, irregular breathing gives rise ... -
Association analyses identify 31 new risk loci for colorectal cancer susceptibility.
(NATURE PUBLISHING GROUP, 2019-05-14)Colorectal cancer (CRC) is a leading cause of cancer-related death worldwide, and has a strong heritable basis. We report a genome-wide association analysis of 34,627 CRC cases and 71,379 controls of European ancestry that ... -
MR guided high intensity focused ultrasound (MRgHIFU) for treating recurrent gynaecological tumours: a pilot feasibility study.
(BRITISH INST RADIOLOGY, 2019-05-16)OBJECTIVE: To assess the feasibility of targeting recurrent gynaecological tumours with MR guided high intensity focused ultrasound (MRgHIFU). METHODS: 20 patients with recurrent gynaecological tumours were prospectively ... -
Synthetic 4D-CT of the thorax for treatment plan adaptation on MR-guided radiotherapy systems.
(IOP PUBLISHING LTD, 2019-05-23)MR-guided radiotherapy treatment planning utilises the high soft-tissue contrast of MRI to reduce uncertainty in delineation of the target and organs at risk. Replacing 4D-CT with MRI-derived synthetic 4D-CT would support ... -
Changing platforms without stopping the train: experiences of data management and data management systems when adapting platform protocols by adding and closing comparisons.
(BMC, 2019-05-29)BACKGROUND: There is limited research and literature on the data management challenges encountered in multi-arm, multi-stage platform and umbrella protocols. These trial designs allow both (1) seamless addition of new ... -
This is a platform alteration: a trial management perspective on the operational aspects of adaptive and platform and umbrella protocols.
(BMC, 2019-05-29)BACKGROUND: There are limited research and literature on the trial management challenges encountered in running adaptive platform trials. This trial design allows both (1) the seamless addition of new research comparisons ... -
Maternal and fetal cardiometabolic recovery following ultrasound-guided high-intensity focused ultrasound placental vascular occlusion.
(ROYAL SOC, 2019-05-31)High-intensity focused ultrasound (HIFU) is a non-invasive method of selective placental vascular occlusion, providing a potential therapy for conditions such as twin-twin transfusion syndrome. In order to translate this ... -
MRI Imaging of the Hemodynamic Vasculature of Neuroblastoma Predicts Response to Antiangiogenic Treatment.
(AMER ASSOC CANCER RESEARCH, 2019-06)Childhood neuroblastoma is a hypervascular tumor of neural origin, for which antiangiogenic drugs are currently being evaluated; however, predictive biomarkers of treatment response, crucial for successful delivery of ... -
ATR Inhibition Potentiates the Radiation-induced Inflammatory Tumor Microenvironment.
(AMER ASSOC CANCER RESEARCH, 2019-06-01)PURPOSE: ATR inhibitors (ATRi) are in early phase clinical trials and have been shown to sensitize to chemotherapy and radiotherapy preclinically. Limited data have been published about the effect of these drugs on the ... -
PD-1 Blockade Following Isolated Limb Perfusion with Vaccinia Virus Prevents Local and Distant Relapse of Soft-tissue Sarcoma.
(AMER ASSOC CANCER RESEARCH, 2019-06-01)PURPOSE: The prevention and treatment of metastatic sarcoma are areas of significant unmet need. Immune checkpoint inhibitor monotherapy has shown little activity in sarcoma and there is great interest in identifying novel ... -
Dosimetry and Gastrointestinal Toxicity Relationships in a Phase II Trial of Pelvic Lymph Node Radiotherapy in Advanced Localised Prostate Cancer.
(ELSEVIER SCIENCE LONDON, 2019-06-01)AIMS: Pelvic lymph node (PLN) radiotherapy for high-risk prostate cancer is limited by late gastrointestinal toxicity. Application of rectal and bowel constraints may reduce risks of side-effects. We evaluated associations ... -
Repeatability and reproducibility of longitudinal relaxation rate in 12 small-animal MRI systems.
(ELSEVIER SCIENCE INC, 2019-06-01)BACKGROUND: Many translational MR biomarkers derive from measurements of the water proton longitudinal relaxation rate R1, but evidence for between-site reproducibility of R1 in small-animal MRI is lacking. OBJECTIVE: To ... -
