Co-Director of Cancer Trials, NHMRC Clinical Trials Centre, University of Alan Coates sets the scene by describing the benefits, Sydney beneficiaries and challenges of cancer clinical trials research. Senior Lecturer in He concludes that cancer trials are a good buy for patients, Cancer Medicine and doctors and society. Clinical Epidemiology, University of Sydney Sue Lockwood considers collaboration between consumers and clinician researchers using the example of breast cancer, Director, Cancer Trials NSW, The Cancer Council NSW and the effects of recent controversies surrounding hormone Medical Oncologist, Sydney Cancer Centre replacement therapy. She concludes with the suggestion Royal Prince Alfred Hospital and Concord Hospitals that researchers provide a community information abstract, Camperdown, NSW summarising the results of their studies for an informed lay audience. These are exciting times. The last 30 years have seen major Mark Rosenthal reflects on the strengths and innovations of reductions in mortality from breast cancer, childhood the Victorian Centre for Developmental Cancer Therapeutics. leukaemia and testis cancer heralding what is possible for The model has been so successful in cancer that it will be other cancers. These improvements are a direct result of clinical applied to neurological and cardiovascular diseases through trials establishing the benefits of mammographic screening, the establishment of Clinical Trials Victoria, which recently adjuvant therapy, and treatments for advanced cancer and received an $8 million grant from the Victorian Government. improving their effectiveness. Changes in community attitudes to sun exposure, tobacco use, and diet should cause major Nicholas Wilcken describes the opportunities and challenges reductions in skin, lung, and colorectal cancer cancers over associated with Australia’s participation in HERA, a large the next 30 years. Despite these major advances, about a international randomised trial of trastuzumab (Herceptin™). quarter of people in the Western world will die from cancer, He concludes that studies like HERA raise new questions about and many more will be affected. Why are clinical trials crucial how trials should be designed and conducted, and reinforce to improving our lot? the need for conducting high quality clinical trials on which to Recent, rapid advances in cell biology, genetics, drug base clinical practice. development, radiation biology and physics, surgery, supportive care and diagnostics have resulted in a plethora of promising Marie Malica describes the development of Cancer Trials new interventions against cancer. These promising new NSW as a model for improving participation in and access to interventions have to be tried, tested and proven before they clinical trials. She emphasises the importance of collaboration, can be adopted in clinical practice. The history of medical inclusion, consumer involvement and improving access and science shows that only a precious few will translate into participation. She concludes that while much needs to be real improvements. Clinical trials are the only reliable way of done, the future looks bright. determining the safety, activity and benefit of these promising new interventions. Leonie Young describes an innovative program to acknowledge the contributions of breast cancer trial participants by The theme of this series is ‘How consumers, clinicians and providing a network, education about breast cancer research researchers can initiate and participate in the best cancer and advocacy training. She concludes that increasing the trials’. Changes in the nature of scientific progress, government community’s awareness of the benefits of breast cancer trials involvement, commercial interests, and regulatory requirements will also help other areas. are forcing us all to rethink our roles in oncology research. Life is getting more complicated, but major improvements are The authors were selected because of their involvement in innovative, successful projects with lessons that I thought on offer. Many have argued, in Australia and overseas, that were applicable beyond their particular area, to other areas of increasing participation and access to high-quality cancer trials oncology and medicine. Authors were asked to focus on what is the best way to improve outcomes for people affected by was innovative and interesting for a general audience, and to cancer. Getting cancer trials on the local political agenda may highlight lessons applicable to cancer trials research in general. be our major battle in the war against cancer.
