Summary
Screening for bowel cancer (CRC) is an important public health initiative. It is most effective when undertaken regularly but there is little research on what personal factors relate to ongoing participation in a screening program. This study will determine the factors associated with ongoing participation in CRC screening and will lead to better screening programs and improved health benefits. This study directly addresses the Cancer Australia priority area re improving screening programs.

There is good evidence that population screening for bowel cancer (CRC), based on the detection of blood in stools, is effective in reducing deaths from bowel cancer by around 30-40%.

Screening depends on the use of a simple test to identify those who most need the complex and costly test which is capable of accurately detecting curable cancers and precancer lesions. This can be achieved with moderate effectiveness using simple tests (FOBTs) which detect microscopic amounts of blood in the faeces. If we are to reduce the rate of death from CRC, we must have an effective way of encouraging people to do these tests. While much has been learnt from experience with screening for breast and cervical cancer, CRC presents a series of quite different issues that have never been comprehensively studied. These are: (1) men and women need to be screened. (2) symptoms due to CRC are more complex , (3) the high-risk settings for CRC are much more complex), (4) the community is not as aware of the benefit of screening, (5) the initial test can be performed at personal convenience in one's home, (6) participants must handle bodily excretions, and (7) inconvenience of attending a central facility is avoided. We will survey participants and non-participants to more accurately identify the barriers to screening, and the proportion who have not participated for informed reasons. To test the real value of attempts to overcome these, we will then offer screening by various approaches designed to overcome these. We are in a unique position to do this as we have well-identified populations who have been offered faecal occult blood test (FOBT)-based screening These studies will assist in the design and implementation of effective screening programs for the early detection of CRC in Australia, which in the long term will significantly reduce deaths from this disease.Read moreRead less

Summary
This study will determine the impact of a fully developed computerised Personalised Decision Support (PDS) package on colorectal cancer screening participation. The PDS tool is designed to guide people through the decision processes relevant to deciding whether to undertake screening. The PDS presents personally tailored messages aimed at progressing individuals towards screening test use and has the potential to supplement traditional paper methods of increasing screening participation.

There is good evidence that population screening, based on the detection of blood in faeces, is effective in reducing deaths from bowel cancer (CRC) by around 30-40%. The process depends on the use of a simple faecal occult blood test (FOBT) to identify those who need a more complex and costly test (colonoscopy), which is capable of accurately detecting curable cancers and precancers so that they can be removed.

The process depends on the use of a simple faecal occult blood test (FOBT) to identify those who need a more complex and costly test (colonoscopy), which is capable of accurately detecting curable cancers and precancers so that they can be removed. If we are to reduce deaths from CRC at the population level, we must have an effective way of encouraging as many people as possible to do FOBT tests. While much has been learnt about how to offer screening from experience with programs for breast and cervical cancer, CRC screening involves different behavioural, psychological and social issues. We need to better understand how these factors influence participation in CRC screening. We plan a series of studies that will lead to improvements in participation in CRC screening programs: a) a survey of a randomly selected group of the general population to measure a range of behavioural features that are of importance to CRC screening, especially as they relate to participation. b) an offer of FOBTscreening to those invited to complete the survey, to match population characteristics with intentions and actual participation, c) on the basis of these studies, to design new screening program strategies, especially in relation to the communication of messages to encourage community participation, d) to test the effectiveness of the new communication strategies by offering FOBT screening to another randomly selected group from the general population. This will allow us to optimise the delivery of messages that encourage participation. If we can design a better communication strategy that achieves an increase in screening participation and has minimum cost implications, we will substantially reduce the number of deaths from CRC in Australia.Read moreRead less

Other RNA-binding proteins belonging to the same broad group of proteins are responsible for a host of disease states in mammals including mental retardation, myotonic dystrophy, Huntington?s disease and cancers. Considering the wealth of knowledge accumulated that implicates these proteins to human dysfunction surprisingly few of these RNA-binding proteins have been identified. We have shown that the novel protein discovered in our laboratory is perturbed in cancer and we are interested in characterising its putative role in cancer. The results established in our laboratory so far would indicate that generally, G3BP-2 is expressed in normal tissue and it expression changes in some cancers studied so far. Considering that G3BP-2 lies in a pathway known to be involved in cancer progression it is important to understand what effects the inappropriate expression of G3BP-2 may have on cancer progression and survival. This project is designed to characterise what signals the cell uses to control these proteins and in turn which genes these may effect. In this way we may be able to determine how external signals may effect tumour progression and on what genes this influence is expressed. It would be hoped that this project would increase our understanding of cancer and potentially lead to new diagnostic reagents and therapies in the treatment of cancer.Read moreRead less

This will involve mailing bowel testing kits direct to eligible consumers at their homes. To minimise inequalities in accessing screening and to ensure effectiveness of the program, information and instructions for testing will have to be accessible to participants from low as well as high educational backgrounds. This project will evaluate communication strategies to achieve this. Reliance on written information has rapidly increased within healthcare. In particular, the use of patient decision aids to support and inform health decisions is rapidly increasing. The need to improve information in screening programs has been particularly highlighted and decision aids provide an evidence based approach to achieve this. However, whilst there is level 1 evidence that decision aids improve the decision making process for consumers, research has been carried out almost exclusively among educated participants with high literacy. There is concern that the needs of adults with low education and limited literacy have been ignored. The proposed study is 2 phased. Phase I will test optimal quantitative risk communication formats for adults with low education and literacy. Phase 2 will evaluate a tailored low literacy decision aid for FOBT screening. The trial will test whether the decision aid can increase knowledge of screening, increase involvement in decisions and improve the quality of decision making among adults with low education, and will examine its impact on screening intentions and behaviour. This is a highly significant study. Screening providers need better ways to inform consumers of screening programs that are accessible to a diverse audience and equitable across the target population. This study will have direct implications for use in the national bowel cancer screening program.Read moreRead less
BEST-Australia: A Phase II Study Of Non-Endoscopic Screening For Barretts Oesophagus In Primary Care

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.
