Intravenous delivery of oncolytic reovirus to brain tumor patients immunologically primes for subsequent checkpoint blockade.
(AMER ASSOC ADVANCEMENT SCIENCE, 2018-01-03)Immune checkpoint inhibitors, including those targeting programmed cell death protein 1 (PD-1), are reshaping cancer therapeutic strategies. Evidence suggests, however, that tumor response and patient survival are determined ... -
Intravenous Oncolytic Vaccinia Virus Therapy Results in a Differential Immune Response between Cancer Patients.
(MDPI, 2022-04-27)Pexa-Vec is an engineered Wyeth-strain vaccinia oncolytic virus (OV), which has been tested extensively in clinical trials, demonstrating enhanced cytotoxic T cell infiltration into tumours following treatment. Favourable ... -
Intrinsic susceptibility MRI identifies tumors with ALKF1174L mutation in genetically-engineered murine models of high-risk neuroblastoma.
(PUBLIC LIBRARY SCIENCE, 2014-03-25)The early identification of children presenting ALK(F1174L)-mutated neuroblastoma, which are associated with resistance to the promising ALK inhibitor crizotinib and a marked poorer prognosis, has become a clinical priority. ... -
Introducing the concept of spiral microbeam radiation therapy (spiralMRT).
(IOP PUBLISHING LTD, 2019-03-08)MOTIVATION: With interlaced microbeam radiation therapy (MRT) a first kilovoltage radiotherapy (RT) concept combining spatially fractionated entrance beams and homogeneous dose distribution at the target exists. However, ... -
Investigating intracranial tumour growth patterns with multiparametric MRI incorporating Gd-DTPA and USPIO-enhanced imaging.
(WILEY, 2016-11-01)High grade and metastatic brain tumours exhibit considerable spatial variations in proliferation, angiogenesis, invasion, necrosis and oedema. Vascular heterogeneity arising from vascular co-option in regions of invasive ... -
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 ... -
Investigating the Contribution of Collagen to the Tumor Biomechanical Phenotype with Noninvasive Magnetic Resonance Elastography.
(AMER ASSOC CANCER RESEARCH, 2019-11-15)Increased stiffness in the extracellular matrix (ECM) contributes to tumor progression and metastasis. Therefore, stromal modulating therapies and accompanying biomarkers are being developed to target ECM stiffness. Magnetic ... -
Investigating the contribution of hyaluronan to the breast tumour microenvironment using multiparametric MRI and MR elastography.
(WILEY, 2023-06-01)Hyaluronan (HA) is a key component of the dense extracellular matrix in breast cancer, and its accumulation is associated with poor prognosis and metastasis. Pegvorhyaluronidase alfa (PEGPH20) enzymatically degrades HA and ... -
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 ... -
Investigating the possible causal role of coffee consumption with prostate cancer risk and progression using Mendelian randomization analysis.
(WILEY, 2017-01-15)Coffee consumption has been shown in some studies to be associated with lower risk of prostate cancer. However, it is unclear if this association is causal or due to confounding or reverse causality. We conducted a Mendelian ... -
Investigating the temporal dynamics of T cells following cancer immunotherapy
(Institute of Cancer Research (University Of London), 2024-05-30)The blockade of immune checkpoints PD1 and CTLA4 have become a standard treatment for the treatment of melanoma. However, mechanistic understanding of how the immunotherapy works remains to be achieved. It is largely unknown ... -
Investigating the Vascular Phenotype of Subcutaneously and Orthotopically Propagated PC3 Prostate Cancer Xenografts Using Combined Carbogen Ultrasmall Superparamagnetic Iron Oxide MRI.
(Ovid Technologies (Wolters Kluwer Health), 2016-10-01)The aim of this study was to use the combined carbogen-ultrasmall superparamagnetic iron oxide (CUSPIO) magnetic resonance imaging (MRI) method, which uses spatial correlations in independent susceptibility imaging biomarkers, ... -
Investigation of In Vivo skin stiffness anisotropy in breast cancer related lymphoedema.
(ELSEVIER SCI LTD, 2016-01-04)There is a limited range of suitable measurement techniques for detecting and assessing breast cancer related lymphoedema (BCRL). This study investigated the suitability of using skin stiffness measurements, with a particular ... -
