Summary
We will use mammograms and family history information collected by BreastScreen to update and improve our automated measures of mammographic density for the new era of digital mammograms. We will then develop a new risk prediction tool by combining the measure of mammographic density for digital mammograms with other risk factors so that information on risk can be given to women at the time of their scans. The results of this project will enable Australian women to receive tailored screening.
Exposure To High Dose Estrogens In Adolescence: Long Term Effects On Mammographic Breast Density

Summary
Breast density is a well established risk factor for breast cancer, and has been shown to be reversibly influenced by hormone exposures in adult life. As one of the important roles of sex hormones during puberty is mammary cell proliferation, it is plausible that exposures at this earlier life stage might have a sustained influence on breast tissue composition and density, and subsequent breast cancer risk. This project aims to increase our understanding of the influence of sex hormones in adole ....Breast density is a well established risk factor for breast cancer, and has been shown to be reversibly influenced by hormone exposures in adult life. As one of the important roles of sex hormones during puberty is mammary cell proliferation, it is plausible that exposures at this earlier life stage might have a sustained influence on breast tissue composition and density, and subsequent breast cancer risk. This project aims to increase our understanding of the influence of sex hormones in adolescence on breast cancer risk by testing the hypothesis that exposure to large doses of sex hormones during adolescence has long-term effects on mammographic density. This will be done by comparing the mammographic densities of women who were treated with high doses of estrogen for tall stature during adolescence with women who were similarly assessed for tall stature but not treated. No previous study in humans has examined the long-term effects on breast tissue of high dose estrogen exposure at this early life stage. This is not surprising, given the difficulty in finding a suitable exposed population. This cohort of women, assessed or treated for tall stature, provides us with a unique opportunity to examine these influences. This research will add to our understanding of the influence of sex hormones in adolescence on mammographic density and breast cancer risk. If hormonal factors in adolescence are shown to influence mammographic density, this may lead to new avenues for breast cancer prevention efforts that are targeted much earlier in life. This information may lead to new research directions examining adolescent hormonal exposures (both endogenous and exogenous) and their influence on breast tissue.Read moreRead less
Implementation Of A New, Inexpensive And High-throughput Matrix Assisted Laser Desorption / Ionization _ Time Of Flight Mass Spectrometry Test For Superior Detection Of Fragile X Syndrome In Targeted Diagnostics And Newborn Population Screening.

Summary
Background: The Fragile X Syndrome (FXS) is the most common form of inherited intellectual disability. There are now a number of treatments for FXS. However, often this disorder is not clearly recognized. We have developed a novel FXS test that could resolve this issue. Our objective is to develop a commercial package that describes suitability of our test for diagnostic use. If successful this could potentially leading to improvement in the prognosis for FXS children through early treatment int ....Background: The Fragile X Syndrome (FXS) is the most common form of inherited intellectual disability.

Risks And Benefits Of Breast Cancer Screening: BreastScreen WA Cohort Study Of Overdiagnosis And Breast Cancer Mortality

Funding Amount
$201,524.00
Summary
Overdiagnosis is the major downside of screening for breast cancer. This occurs when screening detects cancers that would not have caused symptoms in the woman's lifetime. This study aims to quantify the amount of overdiagnosis that occurs in the Australian breast cancer screening program (BreastScreen)
Massively Parallel Sequencing And PCR Optimised For DNA-based Diagnostics And Discovery

Funding Amount
$201,664.00
Summary
The next generation of medical diagnostics and discovery in disease research will involve the marriage of PCR, a tool used to amplify large amounts of DNA from small starting quantities, and �next generation� sequencing, a way to sequence lots and lots of DNA on a single instrument run. This study aims to describe methods which allow scientists to screen hundreds of disease genes in hundreds of people simultaneously with high accuracy and high efficiency.
Characterization Of A Novel Epigenetic Boundary And Long Range Epigenetic Modifications Specific To FMR1 Expansion Carriers With Behavioural And Cognitive Disorders - Implications For Earlier Diagnosis And Treatment.

Funding Amount
$670,836.00
Summary
Fragile X Syndrome (FXS) is the most common form of inherited intellectual disability and autism and is caused by a faulty switch in the gene FMR1. We have discovered new DNA regions important in FXS. The project aims to explain how these new regions regulate the FMR1 gene. This is essential for the discovery and validation of new avenues for earlier diagnosis, treatments and therapies for children and adults with FMR1 disorders and also for informing reproductive decisions.
A Glint Or A Squint Should Make You Think! A Randomised, Controlled Study To Determine The Impact Of An Eye-health Awareness Program For New Parents

Funding Amount

Summary
Retinoblastoma (RB) is a rare, blinding and sometimes fatal, childhood eye cancer. The earliest diagnosis affords the child the best prognosis for retaining their sight, eye or their life. This project will examine parents’ current understanding of the symptoms and signs for RB, identify barriers to early diagnosis of RB, and to develop, implement and evaluate a sustainable public health awareness program to potentially improve the timing of diagnosis and subsequent outcomes for this disease.
About 14,000 cases of bowel cancer occur annually in Australia despite the availability of life-saving screening. Most people do not receive recommended screening colonoscopy. We will look at why people at high-risk avoid screening and why people at average risk seek unnecessary screening. We will analyse family history and contacts with the healthcare system that impact screening decisions. We will determine the impact of screening on reducing the number of new cases and deaths.
A Functional Assay To Classify Genetic Variants In Lynch Syndrome

Funding Amount
$368,195.00
Summary
At least one person in every 1000 is affected by Lynch syndrome, in which faulty DNA repair machinery causes high rates of cancer. People with Lynch syndrome can have their risk of cancer cut substantially with regular screening. However, we often struggle to understand whether people with 'non-standard' DNA sequences in particular genes actually have Lynch syndrome. This project develops a simple test that will tell clinicians whether a given sequence change relates to Lynch syndrome or not.

Summary
Colorectal cancer (CRC) is the second most common cancer in Australia with poor patient outcome due to late detection of the disease. We have developed a simple blood based test that can diagnose individuals with CRC at an early stage when the chance of cure is greater than 80%.
