Development and external validation of nomograms in oropharyngeal cancer patients with known HPV-DNA status: a European Multicentre Study (OroGrams).
(SPRINGERNATURE, 2018-06-01)BACKGROUND: The proxy marker for human papillomavirus (HPV), p16, is included in the new AJCC 8th/UICC 8th staging system, but due to incongruence between p16 status and HPV infection, single biomarker evaluation could ... -
Development and responses of brain metastases during treatment with trastuzumab emtansine (T-DM1) for HER2 positive advanced breast cancer: A single institution experience.
(WILEY, 2018-05-01)Ado-trastuzumab emtansine (T-DM1) is an antibody-drug conjugate that does not cross an intact blood-brain barrier. In the EMILIA trial of T-DM1 vs capecitabine/lapatinib for HER2 positive advanced breast cancer, all patients ... -
Development and validation of a follow-up methodology for a randomised controlled trial, utilising routine clinical data as an alternative to traditional designs: a pilot study to assess the feasibility of use for the BladderPath trial.
(BMC, 2020-10-31)BACKGROUND: Bladder cancer outcomes have not changed significantly in 30 years; the BladderPath trial (Image Directed Redesign of Bladder Cancer Treatment Pathway, ISRCTN35296862) proposes to evaluate a modified pathway ... -
Development of a new fusion-enhanced oncolytic immunotherapy platform based on herpes simplex virus type 1.
(BMJ PUBLISHING GROUP, 2019-08-10)BACKGROUND: Oncolytic viruses preferentially replicate in tumors as compared to normal tissue and promote immunogenic cell death and induction of host systemic anti-tumor immunity. HSV-1 was chosen for further development ... -
Development of a temperature-controlled phantom for magnetic resonance quality assurance of diffusion, dynamic, and relaxometry measurements.
(WILEY, 2016-06-01)PURPOSE: Diffusion-weighted (DW) and dynamic contrast-enhanced magnetic resonance imaging (MRI) are increasingly applied for the assessment of functional tissue biomarkers for diagnosis, lesion characterization, or for ... -
Development of methods to assess the predictive power of pre-therapy imaging for selective internal radiation therapy
(Institute of Cancer Research (University Of London), 2020-12-31)Pre-therapy Technetium-99m (99mTc)-MAA SPECT may be used to predict the 90Y absorbed dose in selective internal radiation therapy (SIRT), while post-therapy 90Y bremsstrahlung SPECT may be used to measure the delivered ... -
Development of Real-Time Motion-Including Dose Reconstruction on a Unity MR-Linac system
(Institute of Cancer Research (University Of London), 2024-03-12)The first part of my thesis is concerned with estimating the motion of organs and other critical anatomical structures during radiotherapy treatments. I use 2D cine images acquired during MR-Linac treatments and compare ... -
Diagnostic and Therapeutic Biomarkers in Glioblastoma: Current Status and Future Perspectives.
(HINDAWI LTD, 2017-01-01)Glioblastoma (GBM) is a primary neuroepithelial tumor of the central nervous system, characterized by an extremely aggressive clinical phenotype. Patients with GBM have a poor prognosis and only 3-5% of them survive for ... -
Diagnostic ultrasound probes: a typology and overview of technologies
(Walter de Gruyter GmbH, 2018-09-01)<jats:title>Abstract</jats:title> <jats:p>The routine clinical use of diagnostic ultrasound (US) has spread considerably worldwide in recent decades. This is due in large part to the availability of US probes ... -
Diagnostic Utility of Molecular and Imaging Biomarkers in Cytological Indeterminate Thyroid Nodules.
(2018-04)Indeterminate thyroid cytology (Bethesda III and IV) corresponds to follicular-patterned benign and malignant lesions, which are particularly difficult to differentiate on cytology alone. As ~25% of these nodules harbor ... -
Dicentric Dose Estimates for Patients Undergoing Radiotherapy in the RTGene Study to Assess Blood Dosimetric Models and the New Bayesian Method for Gradient Exposure.
(RADIATION RESEARCH SOC, 2018-09-20)The RTGene study was focused on the development and validation of new transcriptional biomarkers for prediction of individual radiotherapy patient responses to ionizing radiation. In parallel, for validation purposes, this ... -
Dichloroacetate induces autophagy in colorectal cancer cells and tumours.
(NATURE PUBLISHING GROUP, 2014-07-15)BACKGROUND: Dichloroacetate (DCA) has been found to have antitumour properties. METHODS: We investigated the cellular and metabolic responses to DCA treatment and recovery in human colorectal (HT29, HCT116 WT and HCT116 ... -
Differential and longitudinal immune gene patterns associated with reprogrammed microenvironment and viral mimicry in response to neoadjuvant radiotherapy in rectal cancer.
(BMJ PUBLISHING GROUP, 2021-03-01)BACKGROUND: Rectal cancers show a highly varied response to neoadjuvant radiotherapy/chemoradiation (RT/CRT) and the impact of the tumor immune microenvironment on this response is poorly understood. Current clinical tumor ... -
Differentiated thyroid cancer patients potentially benefitting from postoperative I-131 therapy: a review of the literature of the past decade.
(SPRINGER, 2019-10-15)BACKGROUND: Since the last major review of literature on the benefit of I-131 therapy, the continued debate on postoperative radioiodine treatment (RIT) in differentiated thyroid carcinoma (DTC) has led to a number of ... -
Diffusion model comparison identifies distinct tumor sub-regions and tracks treatment response.
(WILEY, 2020-09-01)PURPOSE: MRI biomarkers of tumor response to treatment are typically obtained from parameters derived from a model applied to pre-treatment and post-treatment data. However, as tumors are spatially and temporally heterogeneous, ... -
