Summary
Chronic Obstructive Pulmonary Disease (COPD) is a common problem for current or ex smokers but is often undiagnosed. Effective treatment is available so early diagnosis is important. In this study practice nurses will identify patients who are at risk of COPD and undertake case finding. Patients newly diagnosed with COPD will then be offered a novel management intervention involving the GP and practice nurse working in partnership.

Summary
AIMS This study will assess how melanoma is diagnosed in Queensland, and if improvements can be made. It will assess if skin screening gives earlier diagnosis of some melanomas, and also if it leads to the diagnosis of some thin melanomas which would not progress if left alone. SIGNIFICANCE Melanoma is the most common invasive cancer in Queensland, with some 1,963 people diagnosed annually with the disease. The outlook for these patients varies dramatically with the depth of invasion of melanoma ....AIMS This study will assess how melanoma is diagnosed in Queensland, and if improvements can be made. It will assess if skin screening gives earlier diagnosis of some melanomas, and also if it leads to the diagnosis of some thin melanomas which would not progress if left alone. SIGNIFICANCE Melanoma is the most common invasive cancer in Queensland, with some 1,963 people diagnosed annually with the disease. The outlook for these patients varies dramatically with the depth of invasion of melanoma. Melanoma diagnosed and treated when very thin has an excellent long-term outcome, whereas the outcome for deeply invasive melanoma is much less favourable. Improvements to diagnosis are currently our best hope of reducing deaths and serious distress from this disease. This will be the largest study in the world of the process of diagnosis of melanoma: information on how melanoma presents, and the time between presentation and diagnosis will be compared between thin and deeply invasive melanoma. Results may indicate areas for improvement in education or health services. The use of screening, either by individuals themselves or by health professionals, has the potential to achieve early diagnosis. However, there is currently no good information on whether screening is actually effective. This study will assess the impact of self-screening and doctor screening on the depth of invasion of melanoma at presentation, and ultimately on the likelihood of dying from melanoma. The study will also assess the potential impact of screening on the over-diagnosis of lesions which while labeled as melanoma, may in fact be biologically non-progressive. This is an important issue of current concern internationally. This study will be one of only two studies in the world currently addressing this issue. This project is directly relevant to the early detection and optimum management of the most common invasive cancer in Queensland, and will have relevance internationally.Read moreRead less
Circulating Tumour DNA (ctDNA) As A Diagnostic Tool In Colorectal Cancer: Role In Screening And Early Detection Of Metastatic Or Recurrent Disease

Summary
These studies will be exploring the value of using a blood test to detect cancer DNA as a screening test for colorectal cancer. This test promises to be superior to faecal blood testing, which is currently performed as part of the National Bowel Cancer Screening Program. It may also have advantages over colonoscopy as a screening tool. Given the likely acceptability of having a blood based screening test, it is expected that participation rates in bowel cancer screening, which has been shown to ....These studies will be exploring the value of using a blood test to detect cancer DNA as a screening test for colorectal cancer.

It may also have advantages over colonoscopy as a screening tool. Given the likely acceptability of having a blood based screening test, it is expected that participation rates in bowel cancer screening, which has been shown to save lives, will be greatly increased.Read moreRead less
BEST-Australia: A Phase II Study Of Non-Endoscopic Screening For Barretts Oesophagus In Primary Care

Funding Amount
$513,481.00
Summary
Barrett's oesophagus is common in people with heartburn and may progress to oesophageal cancer. Most cases of oesophageal cancer are diagnosed at a late stage when chances of survival are poor. Currently Barrett's is only diagnosed by endoscopy. We will test how effective and acceptable a non-endoscopic sponge capsule and novel laboratory test is at detecting Barrett's oesophagus early. This could potentially enable early detection of this pre-cancerous condition in general practice.

Vision loss is not just a personal health burden, but a huge socio-economical burden. Management of major vision-threatening eye diseases such as diabetic retinopathy, age-related macular degeneration and glaucoma will be improved if we can successfully identified persons at risk of developing the disease before clinical presentation to benefit from preventive treatment.

Development Of A Slit Scanning Laser Ophthalmoscope As A Screening Tool In Glaucoma Diagnostics

Funding Amount
$195,830.00
Summary
Glaucoma is typified by progressive optic disc cupping and loss of fibres with consequent characteristic field defects. Direct imaging of the retina and quantitative assessment of such images greatly increases early diagnosis of this blinding disease. The proposed device, a laser line scanning ophthalmoscope, could support non-invasive imaging to obtain 3-D information in a simple and cost effective way. This could provide objective clinical parameters to support the decision making process.

Summary
In Victoria alone around 500000 Pap smears a year are examined for evidence of cancer of the cervix or conditions that may lead to cancer. This is a time consuming, labour intensive and costly process with a relatively high failure rate. A number of alternative techniques have been explored in the last decade with a view to providing a diagnostic technique that is free of human error, more reliable than the Pap method and easily used.

This is a time consuming, labour intensive and costly process with a relatively high failure rate. A number of alternative techniques have been explored in the last decade with a view to providing a diagnostic technique that is free of human error, more reliable than the Pap method and easily used. An alternative technique based on using infrared light to probe smears shows promise in providing such an easily automated reliable method. We, and others have spent a number of years exploring this technique and have solved a number of the problems associated with it. Based on our work in the field and the work of others we now wish to develop a methodology using an infrared micro-imaging spectrometer combined with multivariate statistics that can be used to diagnose cervical cancer and the conditions that lead to cervical cancer.Read moreRead less
Comparative Effectiveness Of Breast Tomosynthesis And Mammography In Real-world Population Screening: Evidence To Underpin And Improve Breast Cancer Screening

Funding Amount
$1,851,430.00
Summary
This research addresses key evidence gaps in breast cancer screening by investigating tomosynthesis (3D mammography) versus standard 2D mammography screening to establish the effectiveness of tomosynthesis in Australia and internationally, including impact on cancers not detected at screening that progress clinically. Large-scale studies will be done in real world screening services including a prospective comparative study planned collaboratively with BreastScreen to guide screening policy.
Understanding Causes Of The Rising Incidence Of Thyroid Cancer – What Can Mutations In The BRAF Oncogene Tell Us About Causes And Diagnostic Pathways For Thyroid Cancer?
Funder

Funding Amount
$610,222.00
Summary
The occurrence of thyroid cancer has increased rapidly over the last 25 years but the cause is unknown. The increase may reflect ‘over-diagnosis’ of less harmful cancers or greater exposure to causes of this cancer. Evidence suggests that a gene mutation (BRAF) in thyroid cancers is important in understanding the drivers of the increase. This study will examine the increase in thyroid cancer by investigating causes and diagnostic pathways considering the presence or absence of BRAF mutations.
