Summary
There is clear evidence that physical activity can reduce the risk of developing bowel cancer and some evidence suggesting it may decrease the risk of a recurrence of bowel cancer. This study will provide reliable evidence as to whether people who participate in a structured physical activity programme after treatment for stage II or III colorectal cancer can increase their likelihood of being alive without a cancer recurrence at three years, compared to those who have standard follow-up.

Summary
Radiation treatment alone is given to many cancer patients, however often it does not prevent cancers from recurring. Significant promise is offered by new drugs that target molecules which play a key role in cancer growth, and combining these drugs with radiation treatment may lead to improved patient outcomes. Understanding how these drugs enhance the anti-cancer effects of radiation is critical to selecting the most appropriate patients for treatment with this combination.

Summary
Adjuvant chemotherapy, used in addition to surgery and radiation, improves recurrence and survival rates in women with early breast cancer. These gains must be balanced against the side effects and inconvenience of chemotherapy including hair loss, nausea, tiredness and risk of infection. This study will determine the gains considered necessary to make modern adjuvant chemotherapy for early breast cancer worthwhile by asking women who have had such treatment.

These gains must be balanced against the side effects and inconvenience of chemotherapy including hair loss, nausea, tiredness and risk of infection. This study will determine the gains considered necessary to make modern adjuvant chemotherapy for early breast cancer worthwhile by asking women who have had such treatment. It will determine factors that might influence the gain considered necessary, such as the kind of treatment, the severity of the side effects experienced, social and other factors. Three hundred women who have had modern adjuvant chemotherapy in an ongoing international clinical trial will be recruited and interviewed. The interviews are standardised, scripted and administered by trained researchers to avoid influencing the subjects. Diagrams and props are used to make the questions clearer. Evaluation of these aids is an additional aspect of the project. This information will be invaluable for women and clinicians considering this potentially curative treatment over the next 15 years. The study will also provide new knowledge on how best to provide information about the benefits of treatment. This can then be applied to discussions about treatment in routine clinical practice. The methods are suitable for a wide range of questions in other diseases and settings. The project will be extended to develop the materials for other questions in breast cancer and other settings.Read moreRead less
A Randomised Trial Of Adjuvant Chemotherapies In Resectable Pancreatic Cancer: ESPAC-3

Summary
Over 1,650 Australians are diagnosed with pancreatic cancer each year. In most cases, surgery will remove the tumour but it is possible that the cancer will return as a result of undetectable disease (micrometastases). The cancer will return and be incurable in the majority of patients. More than 1600 Australians die of the disease every year.

In most cases, surgery will remove the tumour but it is possible that the cancer will return as a result of undetectable disease (micrometastases). The cancer will return and be incurable in the majority of patients. More than 1600 Australians die of the disease every year. This study compares the impact of adding chemotherapy to surgery alone (the current standard of care). The study will also compare the effectiveness of two different types of chemotherapy. Surgical resection of a pancreas tumour is the current standard of care for this disease. It is possible that people treated with chemotherapy after their tumour has been surgically removed may live longer before their disease returns and may liver longer overall. This has been shown to be true in other in cancers; eg. breast and bowel. The side effects of chemotherapy are important and can be severe in some people. Recent studies in advanced pancreatic cancer have suggested that the new drug gemcitabine may be more effective than other drugs. For this reason, the trial compares the outcomes in people treated with gemcitabine to those treated with an older drug 5FU, which has been shown to improve survival in an earlier study by a European group. This trial will determine if chemotherapy in addition to surgery increases the length of time before the disease comes back and survival. If it does, it should become standard practice. This study is an important international initiative that will provide unique information about effectiveness of these treatments and their impact on quality of life from the patient's perspective. This study and the previous European study are the largest of their type ever done. 900 people will take part. This study is being conducted in Australia by the Australasian Gastro-Intestinal Trials in collaboration with the Australian Hepatobilary Association and the NHMRC Clinical Trials Centre.Read moreRead less

Summary
Each year approximately 8000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation' [AD] therapy) can produce shrinkage of prostate cancer. In fact AD has caused temporary but valued relief to millions of men with cancer ....Each year approximately 8000 men in Australia and New Zealand develop prostate cancer which has not spread widely and which is amenable to attempted cure by surgery or radiation. Prostate cancer depends for its growth on the male hormone, testosterone, which circulates in the blood. As a result treatment which reduces testosterone level ('androgen deprivation' [AD] therapy) can produce shrinkage of prostate cancer. In fact AD has caused temporary but valued relief to millions of men with cancer of the prostate that has spread throughout the body for the last five decades, worldwide. It remains uncertain however whether AD administered before surgery or radiation will benefit any of the 8000 men each year who develop localised cancer by shrinking the cancer first. In 1996 a trial involving 800 men across Australia and New Zealand commenced under the auspices of the Trans-Tasman Radiation Oncology Group (TROG) to answer the questions: 1 - Does either 3 or 6 months AD prior to radiotherapy reduce the chances of recurrence of the cancer after radiotherapy? 2 - Does such therapy reduce the volume of tissue requiring radiotherapy and hence the chances of long term side effects after radiotherapy? This grant will support collection of follow-up information from the trial and hence answers to the questions asked.Read moreRead less

Summary
Gastric cancer is the fourth ranked cancer by mortality in Australia. Therapy of gastric cancer is unsatisfactory for two reasons; firstly, how normal stomach cells become cancerous is not well defined. We know long-term infection with the bacteria Helicobacter can lead to these cancers, as can severe acid reflux. The cancers produced by these very different agents look remarkably similar, but must be arising through different pathways. Research to date has not yielded great insight.

Therapy of gastric cancer is unsatisfactory for two reasons; firstly, how normal stomach cells become cancerous is not well defined. We know long-term infection with the bacteria Helicobacter can lead to these cancers, as can severe acid reflux. The cancers produced by these very different agents look remarkably similar, but must be arising through different pathways. Research to date has not yielded great insight. Secondly, existing therapy, especially chemotherapy, tends to provide a Oone size fits all? solution. Whatever the cause, removal at surgery is the best option for treatment. After this, patients are often treated with chemotherapy. Although improvements in patient comfort have been made, very few patients are cured as a result of this treatment. We need more information with which to match the right patient with the right therapy. We will perform high-throughput analysis of comprehensive arrays of human genes that are affected in gastric cancer. Biopsies from cancerous and normal tissue will be obtained when patients have surgery. This tissue will have the RNA (the Omessage? from each gene) labelled with chemical tags and then applied to DNA Omicrochips?. Each microchip contains about 5000 gene targets; the RNA binds the matching DNA and produces a light reaction. We can read the light output from these 5000 (or more) signals, and perform complex statistical analysis on the results. This will result in several specific Ogene expression profiles? which we will analyse to see which profiles match each situation. Profiles matching reflux-induced cancer and Helicobacter-induced cancer can be compared. This will suggest what unique processes are occurring in the cancer cells. Profiles of patients responding well to therapy may allow the use of Otailor-made? therapy. In the future, insight into cancer pathways should also allow the design of new and more successful therapies.Read moreRead less
