Summary
Many cancer patients receive expensive and unpleasant therapies that actually do not benefit them. This project will use a new technology that can simultaneously assess the level of expression of thousands of genes. We will test if the pattern of gene expression in tumours can predict the patients' response to therapy. Success will significantly improve the clinical management of advanced cancer patients and provide a rational basis upon which to tailor individualized treatment regimes.
Human RIPC-derived Regulatory Molecules For Cardioprotection Against Ischemic And Cardiopulmonary Bypass Injury

Summary
Our previous work indicates that evoked human blood borne factors confer protection against injury, due to loss of blood flow in heart muscle, when a brief stress is remotely applied to a limb (remote ischemic preconditioning). We have identified these proteins that appear to activate genetic and metabolic regulation of adaptive cell survival processes. We will now test their individual and combined capacity, efficiency and mechanisms of protection in the heart using cell and clinical models.
The Use Of Gene Expression Profiles To Predict The Response To Chemoradiotherapy In Patients With Oesophageal Cancer

Summary
One of the most difficult and clinically important questions facing clinicians treating advanced cancer is deciding which patients will, and who will not, benefit from chemotherapy and-or radiotherapy. This is particularly true for clinicians treating locally advanced oesophageal cancer. Oesophageal cancer is a particularly aggressive tumour with a poor prognosis; the majority of patients die within 1 year of diagnosis with only 10% surviving to 5 years. In an attempt to improve outcomes, the us ....One of the most difficult and clinically important questions facing clinicians treating advanced cancer is deciding which patients will, and who will not, benefit from chemotherapy and-or radiotherapy. This is particularly true for clinicians treating locally advanced oesophageal cancer. Oesophageal cancer is a particularly aggressive tumour with a poor prognosis; the majority of patients die within 1 year of diagnosis with only 10% surviving to 5 years. In an attempt to improve outcomes, the use of preoperative (neoadjuvant) combined chemotherapy and radiotherapy as an adjunct to surgery has become common practice. Neoadjuvant therapy has been reported to induce complete regression of the tumour and increased survival times in 20-30% of patients. However, the lack of any apparent clinical benefit for those patients who are poor or non-responders to chemoradiation implies that a large proportion of patients are being exposed to significant toxicity and potential complication for no obvious advantage. In the project outlined in this application, we propose to use cDNA microarrays, a technology that allows the simultaneous assessment of the level of expression of thousands of genes at once, to profile the gene expression patterns of oesophageal tumours. These profiles will then correlated to the patients response to treatment to determine if the gene expression patterns can be used to predict the clinical response to chemoradiotherapy. Success will open the path to the development of a clinically important test that would significantly improve the management of advanced cancer patients by enabling personalised therapy for individual patients. Not only will this allow the selection of the most effective therapy for each patient but it will also free patients from suffering the nasty side effects of treatments that turn out to be of little benefit.Read moreRead less
Outcomes Of The Arterial Switch Operation: A Multi-centre Study

Summary
The arterial switch operation is the surgery of choice for children born with transposition of the great arteries, a congenital heart defect where the main two vessels of the heart arise from wrong pumping chambers of the heart. There are very few studies looking at adults after this operation. We aim to study all patients who have had an arterial switch. The results of this study will further increase our knowledge of the long term consequences of having the arterial switch operation.
A La CaRT: Australasian Laparoscopic Cancer Of The Rectum Trial. A Phase III Prospective Randomised Trial Comparing Laparoscopic-assisted Resection Versus Open Resection For Rectal Cancer

Summary
The major treatment for rectal cancer is surgical removal of tumour with a large cut through the abdomen. There is a newer, less invasive procedure known as laparoscopic resection which enables the same surgery to be performed using a scope inserted in the abdomen and another smaller incision for removal of the tumour. This study is being conducted to determine whether the newer procedure is as safe and effective as the current procedure. Patients on the trial will be given either laparoscopi
Childhood Lymphatic Malformations: The Mechanism Of Rapamycin In Controlling Growth

Summary
Lymphatic malformations (also known as cystic hygromas or lymphangiomas) cause deformity and pain which can last lifelong. Current treatments help but do not fix all the symptoms. Rapamycin, a drug used for many years in children and adults with kidney transplants, may be useful for treating children with lymphatic malformations. We aim to understand how the drug works on the cells of lymphatic malformations in culture and in an animal model, to develop new and more effective treatments.
