Breast MRI segmentation for density estimation: Do different methods give the same results and how much do differences matter?
(WILEY, 2017-09-01)
PURPOSE: To compare two methods of automatic breast segmentation with each other and with manual segmentation in a large subject cohort. To discuss the factors involved in selecting the most appropriate algorithm for ...
The long-term prognostic and predictive capacity of cyclin D1 gene amplification in 2305 breast tumours.
(BMC, 2019-02-28)
BACKGROUND: Use of cyclin D1 (CCND1) gene amplification as a breast cancer biomarker has been hampered by conflicting assessments of the relationship between cyclin D1 protein levels and patient survival. Here, we aimed ...
A pan-cancer analysis of the frequency of DNA alterations across cell cycle activity levels.
(SPRINGERNATURE, 2020-08-06)
Pan-cancer genomic analyses based on the magnitude of pathway activity are currently lacking. Focusing on the cell cycle, we examined the DNA mutations and chromosome arm-level aneuploidy within tumours with low, intermediate ...
Tumour auto-contouring on 2d cine MRI for locally advanced lung cancer: A comparative study.
(ELSEVIER IRELAND LTD, 2017-12-01)
BACKGROUND AND PURPOSE: Radiotherapy guidance based on magnetic resonance imaging (MRI) is currently becoming a clinical reality. Fast 2d cine MRI sequences are expected to increase the precision of radiation delivery by ...
Public preferences for delayed or immediate antibiotic prescriptions in UK primary care: A choice experiment.
(Public Library of Science (PLoS), 2021-08-01)
BACKGROUND: Delayed (or "backup") antibiotic prescription, where the patient is given a prescription but advised to delay initiating antibiotics, has been shown to be effective in reducing antibiotic use in primary care. ...
Design of SERENA-6, a phase III switching trial of camizestrant in ESR1-mutant breast cancer during first-line treatment.
(FUTURE MEDICINE LTD, 2023-03-01)
ESR1 mutation (ESR1m) is a frequent cause of acquired resistance to aromatase inhibitor (AI) plus cyclin-dependent kinase 4 and 6 inhibitors (CDK4/6i), which is a first-line therapy for hormone-receptor-positive (HR+)/human ...
The shieldin complex mediates 53BP1-dependent DNA repair.
(NATURE PUBLISHING GROUP, 2018-08-02)
53BP1 is a chromatin-binding protein that regulates the repair of DNA double-strand breaks by suppressing the nucleolytic resection of DNA termini1,2. This function of 53BP1 requires interactions with PTIP3 and RIF14-9, ...
Preventative therapy for breast cancer: a clinical experience.
(SPRINGER, 2023-09-01)
BACKGROUND: Breast Cancer incidence in the UK is estimated to rise to 71,000 per year by 2035. Preventative strategies could significantly reduce this. Preventative therapy reduces women's risk of oestrogen receptor positive ...
Assessment of the direct effects of DDAH I on tumour angiogenesis in vivo.
(SPRINGER, 2018-11-01)
Nitric oxide (NO) has been strongly implicated in glioma progression and angiogenesis. The endogenous inhibitors of NO synthesis, asymmetric dimethylarginine (ADMA) and N-monomethyl-L-arginine (L-NMMA), are metabolized by ...
Mapping Hypoxia in Renal Carcinoma with Oxygen-enhanced MRI: Comparison with Intrinsic Susceptibility MRI and Pathology.
(RADIOLOGICAL SOC NORTH AMERICA, 2018-09-01)
Purpose To cross-validate T1-weighted oxygen-enhanced (OE) MRI measurements of tumor hypoxia with intrinsic susceptibility MRI measurements and to demonstrate the feasibility of translation of the technique for patients. ...
