Desmoid fibromatosis through the patients' eyes: time to change the focus and organisation of care?
(SPRINGER, 2019-03-01)PURPOSE: Desmoid fibromatosis (DF) is a rare, unpredictable disease with no established, evidence-based treatments. Individual management is based on consensus algorithms. This study aimed to examine the specific health-related ... -
DESNT: A Poor Prognosis Category of Human Prostate Cancer.
(ELSEVIER, 2018-12-01)BACKGROUND: A critical problem in the clinical management of prostate cancer is that it is highly heterogeneous. Accurate prediction of individual cancer behaviour is therefore not achievable at the time of diagnosis leading ... -
Detecting gas-induced vasomotor changes via blood oxygenation level-dependent contrast in healthy breast parenchyma and breast carcinoma.
(WILEY-BLACKWELL, 2016-08-01)PURPOSE: To evaluate blood oxygenation level-dependent (BOLD) contrast changes in healthy breast parenchyma and breast carcinoma during administration of vasoactive gas stimuli. MATERIALS AND METHODS: Magnetic resonance ... -
Detecting human melanoma cell re-differentiation following BRAF or heat shock protein 90 inhibition using photoacoustic and magnetic resonance imaging.
(NATURE PUBLISHING GROUP, 2017-08-15)Targeted therapies specific to the BRAF-MEK-ERK signaling pathway have shown great promise in the treatment of malignant melanoma in the last few years, with these drugs now commonly used in clinic. Melanoma cells treated ... -
Detection of the prodrug-activating enzyme carboxypeptidase G2 activity with chemical exchange saturation transfer magnetic resonance.
(SPRINGER, 2014-04-01)PURPOSE: The purpose of this study is to evaluate if the differential exchange rates with bulk water between amine and amide protons can be exploited using chemical exchange saturation transfer magnetic resonance (CEST-MR) ... -
Determining the chemical exchange saturation transfer (CEST) behavior of citrate and spermine under in vivo conditions.
(WILEY-BLACKWELL, 2016-09-01)PURPOSE: To estimate the exchange rates of labile (1) H in citrate and spermine, metabolites present in prostatic secretions, to predict the size of the citrate and spermine CEST effects in vivo. METHODS: CEST z-spectra ... -
Developing and validating a simple urethra surrogate model to facilitate dosimetric analysis to predict genitourinary toxicity.
(Elsevier BV, 2024-05-01)PURPOSE: The urethra is a critical structure in prostate radiotherapy planning; however, it is impossible to visualise on CT. We developed a surrogate urethra model (SUM) for CT-only planning workflow and tested its geometric ... -
Development and external validation of a dynamic prognostic nomogram for primary extremity soft tissue sarcoma survivors.
(ELSEVIER, 2019-12-01)BACKGROUND: Prognostic nomograms for patients with extremity soft tissue sarcoma (eSTS) typically predict survival or the occurrence of local recurrence or distant metastasis at time of surgery. Our aim was to develop and ... -
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 ... -
