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 support community for adolescents and young adults (AYAs) with cancer: user statistics, evaluation, and content analysis.
(DOVE MEDICAL PRESS LTD, 2018-01-01)PURPOSE: Peer support is an important unmet need among adolescent and young adult (AYA) cancer patients. This study was conducted to describe the use and evaluation of a Dutch secure online support community for AYA diagnosed ... -
Open-Label, Single-Arm Phase II Study of Pembrolizumab Monotherapy as First-Line Therapy in Patients With Advanced Clear Cell Renal Cell Carcinoma.
(LIPPINCOTT WILLIAMS & WILKINS, 2021-03-20)PURPOSE: Pembrolizumab, a programmed death 1 inhibitor, demonstrated promising single-agent activity in untreated patients with various cancer types. The phase II KEYNOTE-427 study evaluated efficacy and safety of single-agent ... -
OpenMS: a flexible open-source software platform for mass spectrometry data analysis.
(NATURE PORTFOLIO, 2016-08-30)High-resolution mass spectrometry (MS) has become an important tool in the life sciences, contributing to the diagnosis and understanding of human diseases, elucidating biomolecular structural information and characterizing ... -
Operational complexity versus design efficiency: challenges of implementing a phase IIa multiple parallel cohort targeted treatment platform trial in advanced breast cancer.
(BMC, 2022-05-07)BACKGROUND: Platform trial designs are used increasingly in cancer clinical research and are considered an efficient model for evaluating multiple compounds within a single disease or disease subtype. However, these trial ... -
OpEx - a validated, automated pipeline optimised for clinical exome sequence analysis.
(NATURE PORTFOLIO, 2016-08-03)We present an easy-to-use, open-source Optimised Exome analysis tool, OpEx (http://icr.ac.uk/opex) that accurately detects small-scale variation, including indels, to clinical standards. We evaluated OpEx performance with ... -
Opinion: PARP inhibitors in cancer-what do we still need to know?
(The Royal Society, 2022-07-01)PARP inhibitors (PARPi) have been demonstrated to exhibit profound anti-tumour activity in individuals whose cancers have a defect in the homologous recombination DNA repair pathway. Here, we describe the current consensus ... -
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 ... -
Optical photon transport in powdered-phosphor scintillators. Part 1. Multiple-scattering and validity of the Boltzmann transport equation
(AMER ASSOC PHYSICISTS MEDICINE AMER INST PHYSICS, 2013-04)Purpose: In Part 1 of this two-part work, predictions for light transport in powdered-phosphor screens are made, based on three distinct approaches. Predictions of geometrical optics-based ray tracing through an explicit ... -
Optical photon transport in powdered-phosphor scintillators. Part II. Calculation of single-scattering transport parameters
(AMER ASSOC PHYSICISTS MEDICINE AMER INST PHYSICS, 2013-04)Purpose: Monte Carlo methods based on the Boltzmann transport equation (BTE) have previously been used to model light transport in powdered-phosphor scintillator screens. Physically motivated guesses or, alternatively, the ... -
