High-frequency ultrasound for diagnosing skin cancer in adults.
(WILEY, 2018-12-04)
BACKGROUND: Early, accurate detection of all skin cancer types is essential to guide appropriate management and to improve morbidity and survival. Melanoma and squamous cell carcinoma (SCC) are high-risk skin cancers with ...
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. ...
Beam selection for stereotactic ablative radiotherapy using Cyberknife with multileaf collimation.
(ELSEVIER SCI LTD, 2018-12-20)
The Cyberknife system (Accuray Inc., Sunnyvale, CA) enables radiotherapy using stereotactic ablative body radiotherapy (SABR) with a large number of non-coplanar beam orientations. Recently, a multileaf collimator has also ...
Targeting Hypoxia to Improve Non-Small Cell Lung Cancer Outcome.
(OXFORD UNIV PRESS INC, 2018-01-01)
Oxygen deprivation (hypoxia) in non-small cell lung cancer (NSCLC) is an important factor in treatment resistance and poor survival. Hypoxia is an attractive therapeutic target, particularly in the context of radiotherapy, ...
Oxygen Enhanced Optoacoustic Tomography (OE-OT) Reveals Vascular Dynamics in Murine Models of Prostate Cancer.
(IVYSPRING INT PUBL, 2017-01-01)
Poor oxygenation of solid tumours has been linked with resistance to chemo- and radio-therapy and poor patient outcomes, hence non-invasive imaging of oxygen supply and demand in tumours could improve disease staging and ...
Cancer heterogeneity and imaging.
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2017-04-01)
There is interest in identifying and quantifying tumor heterogeneity at the genomic, tissue pathology and clinical imaging scales, as this may help better understand tumor biology and may yield useful biomarkers for guiding ...
Data-driven mapping of hypoxia-related tumor heterogeneity using DCE-MRI and OE-MRI.
(WILEY, 2018-04-01)
PURPOSE: Previous work has shown that combining dynamic contrast-enhanced (DCE)-MRI and oxygen-enhanced (OE)-MRI binary enhancement maps can identify tumor hypoxia. The current work proposes a novel, data-driven method for ...
Evaluation of dynamic contrast-enhanced MRI biomarkers for stratified cancer medicine: How do permeability and perfusion vary between human tumours?
(ELSEVIER SCIENCE INC, 2018-02-01)
BACKGROUND: Solid tumours exhibit enhanced vessel permeability and fenestrated endothelium to varying degree, but it is unknown how this varies in patients between and within tumour types. Dynamic contrast-enhanced (DCE) ...
Detecting gas-induced vasomotor changes via blood oxygenation level-dependent contrast in healthy breast parenchyma and breast carcinoma.
(WILEY-BLACKWELL, 2016-08-01)
PURPOSE: To evaluate blood oxygenation level-dependent (BOLD) contrast changes in healthy breast parenchyma and breast carcinoma during administration of vasoactive gas stimuli. MATERIALS AND METHODS: Magnetic resonance ...
Rethinking the role of clinical imaging.
(ELIFE SCIENCES PUBLICATIONS LTD, 2017-09-06)
Radiomics has the potential to improve the management of cancer patients, but further research is required before it can be adopted into routine clinical practice.
