Leveraging multi-layer imager detector design to improve low-dose performance for megavoltage cone-beam computed tomography.
(IOP PUBLISHING LTD, 2018-01-30)
While megavoltage cone-beam computed tomography (CBCT) using an electronic portal imaging device (EPID) provides many advantages over kilovoltage (kV) CBCT, clinical adoption is limited by its high doses. Multi-layer imager ...
Can Interrogation of Tumour Characteristics Lead us to Safely Omit Adjuvant Radiotherapy in Patients with Early Breast Cancer?
(ELSEVIER SCIENCE LONDON, 2018-03-01)
Adjuvant radiotherapy after breast-conserving surgery has been an important component of the standard of care for early breast cancer. Improvements in breast cancer care have resulted in a substantial reduction in local ...
Risks of breast or ovarian cancer in BRCA1 or BRCA2 predictive test negatives: findings from the EMBRACE study.
(NATURE PUBLISHING GROUP, 2018-12-01)
PURPOSE: BRCA1/BRCA2 predictive test negatives are proven noncarriers of a BRCA1/BRCA2 mutation that is carried by their relatives. The risk of developing breast cancer (BC) or epithelial ovarian cancer (EOC) in these women ...
Magnetic Resonance Imaging-Guided Adaptive Radiation Therapy: A "Game Changer" for Prostate Treatment?
(ELSEVIER SCIENCE INC, 2018-02-01)
Radiation therapy to the prostate involves increasingly sophisticated delivery techniques and changing fractionation schedules. With a low estimated α/β ratio, a larger dose per fraction would be beneficial, with moderate ...
Practice patterns for the radical treatment of nasopharyngeal cancer by head and neck oncologists in the United Kingdom.
(BRITISH INST RADIOLOGY, 2018-05-01)
OBJECTIVE: Advances in radiation delivery, imaging techniques, and chemotherapy have significantly improved treatment options for non-metastatic nasopharyngeal cancers (NPC). However, their impact on the practice in the ...
Investigating the effect of a magnetic field on dose distributions at phantom-air interfaces using PRESAGE® 3D dosimeter and Monte Carlo simulations.
(IOP PUBLISHING LTD, 2018-02-26)
Dosimetric quality assurance (QA) of the new Elekta Unity (MR-linac) will differ from the QA performed of a conventional linac due to the constant magnetic field, which creates an electron return effect (ERE). In this work ...
MRI-based Assessment of 3D Intrafractional Motion of Head and Neck Cancer for Radiation Therapy.
(ELSEVIER SCIENCE INC, 2018-02-01)
PURPOSE: To determine the 3-dimensional (3D) intrafractional motion of head and neck squamous cell carcinoma (HNSCC). METHODS AND MATERIALS: Dynamic contrast-enhanced magnetic resonance images from 56 patients with HNSCC ...
Mutational spectrum in a worldwide study of 29,700 families with BRCA1 or BRCA2 mutations.
(WILEY-HINDAWI, 2018-05-01)
The prevalence and spectrum of germline mutations in BRCA1 and BRCA2 have been reported in single populations, with the majority of reports focused on White in Europe and North America. The Consortium of Investigators of ...
Germline variants in IL4, MGMT and AKT1 are associated with prostate cancer-specific mortality: An analysis of 12,082 prostate cancer cases.
(NATURE PUBLISHING GROUP, 2018-06-01)
BACKGROUND: Prostate cancer (PCa) is a leading cause of mortality and genetic factors can influence tumour aggressiveness. Several germline variants have been associated with PCa-specific mortality (PCSM), but further ...
Bone lesion absorbed dose profiles in patients with metastatic prostate cancer treated with molecular radiotherapy.
(BRITISH INST RADIOLOGY, 2018-01-01)
OBJECTIVE: The aim of this study was to calculate the range of absorbed doses that could potentially be delivered by a variety of radiopharmaceuticals and typical fixed administered activities used for bone pain palliation ...
