Oncolytic Herpes Simplex Virus Inhibits Pediatric Brain Tumor Migration and Invasion.
(CELL PRESS, 2017-06-16)Pediatric high-grade glioma (pHGG) and diffuse intrinsic pontine glioma (DIPG) are invasive tumors with poor survival. Oncolytic virotherapy, initially devised as a direct cytotoxic treatment, is now also known to act via ... -
Oncolytic Immunotherapy for Bladder Cancer Using Coxsackie A21 Virus.
(CELL PRESS, 2018-06-29)As a clinical setting in which local live biological therapy is already well established, non-muscle invasive bladder cancer (NMIBC) presents intriguing opportunities for oncolytic virotherapy. Coxsackievirus A21 (CVA21) ... -
Oncolytic reovirus as a combined antiviral and anti-tumour agent for the treatment of liver cancer.
(BMJ PUBLISHING GROUP, 2018-03-01)OBJECTIVE: Oncolytic viruses (OVs) represent promising, proinflammatory cancer treatments. Here, we explored whether OV-induced innate immune responses could simultaneously inhibit HCV while suppressing hepatocellular ... -
Oncolytic Reovirus-Mediated Recruitment of Early Innate Immune Responses Reverses Immunotherapy Resistance in Prostate Tumors.
(CELL PRESS, 2021-03-26)Prostate cancers are considered "cold" tumors characterized by minimal T cell infiltrates, absence of a type I interferon (IFN) signature, and the presence of immunosuppressive cells. This non-inflamed phenotype is likely ... -
Oncolytic vaccinia virus as a vector for therapeutic sodium iodide symporter gene therapy in prostate cancer.
(NATURE PUBLISHING GROUP, 2016-04-01)Oncolytic strains of vaccinia virus are currently in clinical development with clear evidence of safety and promising signs of efficacy. Addition of therapeutic genes to the viral genome may increase the therapeutic efficacy ... -
Oncolytic vaccinia virus combined with radiotherapy induces apoptotic cell death in sarcoma cells by down-regulating the inhibitors of apoptosis.
(IMPACT JOURNALS LLC, 2016-12-06)Advanced extremity melanoma and sarcoma present a significant therapeutic challenge, requiring multimodality therapy to treat or even palliate disease. These aggressive tumours are relatively chemo-resistant, therefore new ... -
Oncolytic virotherapy induced CSDE1 neo-antigenesis restricts VSV replication but can be targeted by immunotherapy.
(NATURE PORTFOLIO, 2021-03-26)In our clinical trials of oncolytic vesicular stomatitis virus expressing interferon beta (VSV-IFNβ), several patients achieved initial responses followed by aggressive relapse. We show here that VSV-IFNβ-escape tumors ... -
Online adaptive radiotherapy for head and neck cancers on the MR linear Accelerator: Introducing a novel modified Adapt-to-Shape approach.
(ELSEVIER IRELAND LTD, 2021-11-19)INTRODUCTION: The Elekta Unity MR-Linac (MRL) has enabled adaptive radiotherapy (ART) for patients with head and neck cancers (HNC). Adapt-To-Shape-Lite (ATS-Lite) is a novel Adapt-to-Shape strategy that provides ART without ... -
Online dose reconstruction for tracked volumetric arc therapy: Real-time implementation and offline quality assurance for prostate SBRT.
(WILEY, 2017-08-20)PURPOSE: Firstly, this study provides a real-time implementation of online dose reconstruction for tracked volumetric arc therapy (VMAT). Secondly, this study describes a novel offline quality assurance tool, based on ... -
Opportunities for research in molecular radiotherapy.
(2017-03)Cancer has been treated with radiopharmaceuticals for 80 years. A recent National Cancer Research Institute report from the Clinical and Translational Radiotherapy Research Working Group reviews the current status of ... -
Optically and acoustically triggerable sub-micron phase-change contrast agents for enhanced photoacoustic and ultrasound imaging.
(ELSEVIER GMBH, 2017-06-01)We demonstrate a versatile phase-change sub-micron contrast agent providing three modes of contrast enhancement: 1) photoacoustic imaging contrast, 2) ultrasound contrast with optical activation, and 3) ultrasound contrast ... -
Optimal acquisition scheme for flow-compensated intravoxel incoherent motion diffusion-weighted imaging in the abdomen: An accurate and precise clinically feasible protocol.
(WILEY, 2020-03-01)PURPOSE: Flow-compensated (FC) diffusion-weighted MRI (DWI) for intravoxel-incoherent motion (IVIM) modeling allows for a more detailed description of tissue microvasculature than conventional IVIM. The long acquisition ... -
Optimisation of a composite difference metric for prompt error detection in real-time portal dosimetry of simulated volumetric modulated arc therapy
(British Institute of Radiology, 2021-04-01)Objectives: In real-time portal dosimetry, thresholds are set for several measures of difference between predicted and measured images, and signals larger than those thresholds signify an error. The aim of this work is to ... -
Optimising head and neck radiotherapy treatment using adaptive radiotherapy
(Institute of Cancer Research (University Of London), 2021-10-31)Radiotherapy delivery in head and neck cancer (HNC) has dramatically improved recently with the introduction of advanced techniques such as intensity-modulated radiation therapy (IMRT) and image-guided radiation therapy ... -
