DCE-MRI is more sensitive than IVIM-DWI for assessing anti-angiogenic treatment-induced changes in colorectal liver metastases.
(BMC, 2021-12-19)
BACKGROUND: Diffusion weighted imaging (DWI) with intravoxel incoherent motion (IVIM) modelling can inform on tissue perfusion without exogenous contrast administration. Dynamic-contrast-enhanced (DCE) MRI can also ...
Vessel co-option mediates resistance to anti-angiogenic therapy in liver metastases.
(NATURE PUBLISHING GROUP, 2016-11-01)
The efficacy of angiogenesis inhibitors in cancer is limited by resistance mechanisms that are poorly understood. Notably, instead of through the induction of angiogenesis, tumor vascularization can occur through the ...
Association between Adult Height and Risk of Colorectal, Lung, and Prostate Cancer: Results from Meta-analyses of Prospective Studies and Mendelian Randomization Analyses.
(PUBLIC LIBRARY SCIENCE, 2016-09-06)
BACKGROUND: Observational studies examining associations between adult height and risk of colorectal, prostate, and lung cancers have generated mixed results. We conducted meta-analyses using data from prospective cohort ...
Investigating Low-Velocity Fluid Flow in Tumors with Convection-MRI.
(AMER ASSOC CANCER RESEARCH, 2018-04-01)
Several distinct fluid flow phenomena occur in solid tumors, including intravascular blood flow and interstitial convection. Interstitial fluid pressure is often raised in solid tumors, which can limit drug delivery. To ...
Diffusion-weighted MRI for imaging cell death after cytotoxic or apoptosis-inducing therapy.
(NATURE PUBLISHING GROUP, 2015-04-28)
BACKGROUND: Non-invasive serial imaging is desirable to detect processes such as necrotic and apoptotic cell death in cancer patients undergoing treatment. This study investigated the use of diffusion-weighted (DW-) magnetic ...
Functional imaging and circulating biomarkers of response to regorafenib in treatment-refractory metastatic colorectal cancer patients in a prospective phase II study.
(BMJ PUBLISHING GROUP, 2018-08-01)
OBJECTIVE: Regorafenib demonstrated efficacy in patients with metastatic colorectal cancer (mCRC). Lack of predictive biomarkers, potential toxicities and cost-effectiveness concerns highlight the unmet need for better ...
Metabolic biomarkers of response to the AKT inhibitor MK-2206 in pre-clinical models of human colorectal and prostate carcinoma.
(NATURE PUBLISHING GROUP, 2018-10-30)
BACKGROUND: AKT is commonly overexpressed in tumours and plays an important role in the metabolic reprogramming of cancer. We have used magnetic resonance spectroscopy (MRS) to assess whether inhibition of AKT signalling ...
A data-driven statistical model that estimates measurement uncertainty improves interpretation of ADC reproducibility: a multi-site study of liver metastases.
(NATURE PORTFOLIO, 2017-10-26)
Apparent Diffusion Coefficient (ADC) is a potential quantitative imaging biomarker for tumour cell density and is widely used to detect early treatment changes in cancer therapy. We propose a strategy to improve confidence ...
Correlation of Ultrasound Shear Wave Elastography with Pathological Analysis in a Xenografic Tumour Model.
(NATURE PORTFOLIO, 2017-03-13)
The objective of this study was to evaluate the potential value of ultrasound (US) shear wave elastography (SWE) in assessing the relative change in elastic modulus in colorectal adenocarcinoma xenograft models in vivo and ...
Stability of radiomics features in apparent diffusion coefficient maps from a multi-centre test-retest trial.
(NATURE PORTFOLIO, 2019-03-18)
Quantitative radiomics features, extracted from medical images, characterize tumour-phenotypes and have been shown to provide prognostic value in predicting clinical outcomes. Stability of radiomics features extracted from ...
