Circulating Tumour DNA To Monitor Treatment Response And Resistance In Chronic Lymphocytic Leukaemia

Funding Amount
$876,950.00
Summary
Many cancers shed small amounts of DNA (ctDNA) into the patient’s bloodstream and recent advances in genomic technologies now allow levels of ctDNA to be accurately measured in the blood. Changes in ctDNA levels have potential to be used as specific markers of disease progression and/or response to cancer therapy. This project will evaluate if ctDNA can be used to monitor treatment responses and individualise treatment decisions in patients with chronic lymphocytic leukaemia.

Summary
Treatment of ductal carcinoma in-situ (DCIS), a preinvasive form of breast cancer, is aimed at preventing invasive cancer recurrence. Women with higher-risk DCIS have an increased risk of recurrence. This study aims to individualise treatment for women with DCIS to achieve long-term tumour control with minimal treatment toxicity. After local excision of DCIS, radiotherapy (RT) to the whole breast reduces the recurrence rate.

Women with higher-risk DCIS have an increased risk of recurrence. This study aims to individualise treatment for women with DCIS to achieve long-term tumour control with minimal treatment toxicity. After local excision of DCIS, radiotherapy (RT) to the whole breast reduces the recurrence rate. However, it is unclear if escalating radiation dose to the tumour bed in higher-risk women increases tumour control. It is also uncertain if giving fewer but larger radiation doses over 3-4 weeks would achieve the same tumour control as the standard 5-7 week course of RT to improve patient convenience and access to RT. Thus, this multicentre study of 610 women with higher-risk DCIS will investigate if adding a tumour bed radiation boost after whole breast RT improves tumour control, and the shorter RT course achieves the same tumour control as the standard longer course. Currently, the ability to predict the malignant potential of DCIS and RT toxicity is limited. This study will investigate if there are biological and genetic markers predictive of invasive recurrence and normal tissue toxicity in women with DCIS using state of the art technology. Women need to weigh up the likelihood of cancer control against adverse treatment effects to make an informed treatment decision. However, very little is known about the quality of life (QoL) consequences of the diagnosis and treatment of DCIS. In this study, the QoL, psychological distress, perceived risk of invasive cancer recurrence and perceived cosmetic outcomes of women with DCIS, will be assessed using a questionnaire of validated measures. This study will refine treatment for women with DCIS according to their risks of recurrence. It will significantly advance the understanding of the biology of DCIS and its psychological and QoL outcomes after treatment.Read moreRead less
The Genetic And Environmental Determinants Of Amyloid Deposition In Older Individuals: An Amyloid Imaging Study Using The Twin Design

$643,267.00
Summary
Alzheimer’s disease is characterised by the deposition of amyloid plaques in the brain. We don’t fully understand how amyloid deposition occurs and what contribution is made by genetic and environmental factors. Amyloid deposition in the brain can now be quantified during life using positron emission tomography. In this study, we will examine brain amyloid in twins, which will determine what proportion of the pathology is attributable to environmental factors that may be modifiable.

How Do Thick Airway Walls Affect Airway Hyperresponsiveness In Asthma?
Funder
National Health and Medical Research Council
Funding Amount
$382,538.00
Summary
Asthmatic airways narrow too easily, a characteristic called airway hyperresponsiveness (AHR). To understand the cause of asthma we need to understand the cause of AHR. Thickened airway walls could amplify airway narrowing and increase AHR. However, thick airway walls are also stiff, and stiff walls could reduce narrowing and AHR. This project will examine the relationships between AHR and airway wall thickness and stiffness during and after treatment that reduces airway wall thickness.
Molecular Markers Of Phenotype, Therapeutic Responsiveness And Prognosis In Human Cancers.

Summary
This proposal aims to identify molecular markers that can be used to classify subtypes of particular cancers according to their prognosis and response to therapy. This will optimise selection of patients for the most appropriate treatment and lead to the development of new therapeutic strategies.

Researchers at Wollongong will have access to an ion mobility mass spectrometry technology not currently available in Australia that will contribute to our understanding of complicated cellular processes such as chromosome replication. The researchers' experience with this technology will pave the way for introduction of the technology to Australia and benefit the wider scientific community in wide-ranging projects such as development of new antibiotics and vaccines. Students from both institutions will benefit from experiencing science from an international perspective.Read moreRead less

Bacteria are vital agents in earth's biosphere, breaking down and synthesising a wide variety of compounds. Some bacteria cause disease; others are exploited for a range of biotechnological applications. Bacteria have a remarkable ability to survive and thrive in changing conditions. For example, pathogenic bacteria confronted by antibiotics easily evolve resistance to them. With the reality of climate change, we expect more rapid shifts in the structure of bacterial communities, possibly leading to the emergence of new pathogens. The benefits of this project are to discover how the genetic structure of bacteria confer this flexibility, and to help keep Australia at the forefront of research in bioinformatics and mathematical biology.

Insect societies are complex systems. Understanding complex systems is often hampered by our inability to study the individual units that comprise the system without also disturbing the system. Insect societies are unique in that the individual insects can be studied within their natural setting. This project will study foraging behaviour of honey bees with respect to individual decision-making and information transfer. In doing so we will obtain insights in the working of other, less accessible, complex systems such as the mammalian brain or the Australian economy.Read moreRead less

This project aims to develop a new biophysical model of the brain, founded on the recently discovered glymphatic system responsible for waste disposal during sleep. It sets out to formulate, analyse, and validate rigorous new multiscale quantitative modelling – to advance the study of sleep and brain clearance dynamics, at timescales from hours to decades. Among expected outcomes are powerful models ready for application at both population and individual level, and testable predictions concerning the sleep patterns that lead to aggregation of waste in the brain and eventual cognitive decline. Project outcomes should also benefit society and the economy though translation into interventions for sleep disturbance – in future applied research.Read moreRead less
