4D-MRI for thoracic radiotherapy treatment planning and guidance on an MR-linac
Lung cancer currently has a poor prognosis in England and Wales with only 10% of adults surviving five years or more after diagnosis. The poor survival rate demonstrates the need to improve contemporary treatment approaches ... -
Advanced magnetic resonance imaging in lung mesothelioma
(Institute of Cancer Research (University Of London), 2021-07-31)Malignant pleural mesothelioma (MPM) has a rind-like growth pattern and may have both solid disease and pleural fluid, so it is very challenging to accurately categorize change in tumour burden using size-based tumour ... -
Assessment of delivered rectal dose in prostate cancer radiotherapy
(Institute of Cancer Research (University Of London), 2021-11-30)Prostate radiotherapy gives excellent long-term disease control; however, morbidity from treatment can negatively impact quality of life. To minimise the risk of toxicity a treatment plan is created, which meets dose volume ... -
Biological effects of combination therapy with oncolytic reovirus and palbociclib
(Institute of Cancer Research (University Of London), 2021-09-30)Reovirus type 3 Dearing (RtD3) is an oncolytic dsRNA virus with limited single-agent activity in clinical studies but has potential for use in combination regimens. Herein, I sought to discover synergistic drug-virotherapy ... -
Circulating tumour DNA in advanced thyroid cancer
(Institute of Cancer Research (University Of London), 2021-02-28)Conventional biomarkers currently used in thyroid cancer are not disease specific and fluctuate in advanced disease, making interpretation difficult. Circulating tumour DNA (ctDNA) has been shown to be a useful in other ... -
Computational science-enabled radiological pathology for the non-invasive mapping of tumour heterogeneity in childhood neuroblastoma
(Institute of Cancer Research (University Of London), 2021-01-31)Neuroblastoma is a common childhood solid tumour that accounts for 15% of all cancer paediatric deaths. This thesis addresses key deficiencies in our ability to define, monitor and predict neuroblastoma heterogeneity for ... -
Defining novel immune biomarkers of prognosis and immunotherapy sensitivity in gastro-oesophageal and colorectal cancers
(Institute of Cancer Research (University Of London), 2023-11-28)Background Gastro-oesophageal adenocarcinomas (GOAs) frequently recur after resection; prognostic and predictive markers are absent. Mismatch repair-deficient (MMRd) GOAs have high mutational burden, are frequently ... -
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 ... -
Diffusion-Weighted Magnetic Resonance Imaging (DW-MRI) of the normal bone marrow in children and effects of local and systemic cancer therapies
(Institute of Cancer Research (University Of London), 2021-01-31)Bone marrow, one of the largest organs in the body, is a highly proliferative tissue because of its dynamic function in providing the cellular elements of blood. In a paediatric population, the proportion of red marrow ... -
Drug delivery across the blood-brain barrier using short-pulse focused ultrasound and microbubbles for the treatment of diffuse intrinsic pontine glioma
(Institute of Cancer Research (University Of London), 2023-09-01)The blood-brain barrier (BBB) prevents unwanted substances from entering the brain, but also blocks entry of therapeutic agents, posing difficulties for treating brain cancers such as diffuse intrinsic pontine glioma (DIPG) ... -
The effects of oncolytic Maraba virus (MG1) in malignant melanoma
(Institute of Cancer Research (University Of London), 2022-07-31)Despite recent advances in the targeted and immunological treatment of melanoma, the incidence of this malignancy is increasing and is responsible for approximately 60,000 global deaths annually, highlighting the ongoing ... -
An evaluation of contouring and planning methods to expand the role of SBRT with CyberKnife in the treatment of localised prostate and renal cancers
(Institute of Cancer Research (University Of London), 2022-05-31)Technological advancement has led to the substantial evolution of stereotactic body radiotherapy (SBRT). The CyberKnife SBRT platform achieves a high degree of precision through robotic delivery of multiple non-coplanar ... -
Evaluation of dysphagia-optimising radiotherapy techniques in locally advanced oropharyngeal cancer
(Institute of Cancer Research (University Of London), 2020-01-31)Radiation-associated dysphagia (RAD) following chemoradiation in locally advanced oropharyngeal cancers (LA-OPC) can have a devastating impact on patients' quality of life (QoL). Establishing efficient swallow-sparing ... -
An exploration of mechanisms and effects of oncogenic KRAS on the tumour immune microenvironment
(Institute of Cancer Research (University Of London), 2022-07-06)Oncogenic KRAS influences several cancer hallmarks including autonomy from growth promoting signals, enhanced cell survival and altered tumour metabolism. Beyond these, it is now established that oncogenic KRAS can polarise ... -
Finite Element simulation of methods for improving tissue ultrasound backscatter coefficient estimation
(Institute of Cancer Research (University Of London), 2023-10-02)This thesis will describe the efforts to generate Finite Element simulations of methods to improve the accuracy and reliability of backscatter coefficient methods (BSC). BSC measurements are a promising diagnostic tool in ... -
Four-dimensional imaging for radiotherapy planning in children and teenagers
(Institute of Cancer Research (University Of London), 2021-02-28)Respiratory-related organ motion (RROM) is a potential source of geometric uncertainty in RT planning and delivery. Approaches to mitigate its effects are well described in adults. For example, four-dimensional computed ... -
Gustatory function following radiotherapy to the head and neck
(Institute of Cancer Research (University Of London), 2021-11-30)An intact sense of taste provides pleasure, supports sustenance and alerts the body to potential toxins. Patients with head and neck (HNC) who undergo radiotherapy (RT) are at high risk of developing acute and late taste ... -
Improvements in molecular diagnostics and image analysis for detecting and managing cervical cancer
(Institute of Cancer Research (University Of London), 2020-12-31)This thesis addresses improvements in molecular diagnostics and in image analysis, and their combination for managing cervical cancer. Screening cytology has transformed early diagnosis but is resource intensive and highly ... -
Magnetic resonance guided radiotherapy for the treatment of bladder and pancreatic cancer
(Institute of Cancer Research (University Of London), 2022-08-05)Magnetic resonance guided radiotherapy (MRgRT) has many postulated benefits over conventional radiotherapy treatment techniques. Its superior soft tissue definition, lack of imaging related ionising radiation and the ... -
