Summary
For women under 50 years with hormone receptor positive (ER+) breast cancer, adjuvant treatment with chemotherapy, tamoxifen and ovarian ablation are each effective and reduce recurrence. Combining two treatments is more effective than one, although it is uncertain if combining three provides extra benefit. Ovarian ablation by surgery or radiation is permanent, but reversible ovarian suppression by injections is now available.

Combining two treatments is more effective than one, although it is uncertain if combining three provides extra benefit. Ovarian ablation by surgery or radiation is permanent, but reversible ovarian suppression by injections is now available. Three international trials called SOFT, TEXT and PERCHE have been designed for adjuvant therapy of premenopausal women with ER+ breast cancer. These trials take into account regional-country variations in medical practice and different patient choices in this setting. SOFT is for very young women and tests the benefit of adding ovarian suppression in a woman who has received chemotherapy, with tamoxifen planned, but who has not gone into menopause after chemotherapy. The trial also tests if substituting a newer drug called exemestane for tamoxifen, combined with ovarian function suppression is more effective. TEXT is for women who would ordinarily be treated with ovarian suppression plus tamoxifen. The TEXT trial also tests substitution of exemestane for tamoxifen. Exemestane is an aromatase inhibitor. Aromatase inhibitors lower oestrogen levels, but only work if the ovaries are inactive. Recent trials in post menopausal women show aromatase inhibitors are more effective than tamoxifen, and we aim to replicate that improvement in younger women by combining exemestane with ovarian suppression. PERCHE is for women in whom the benefit of chemotherapy is uncertain, for example those with limited or no spread to lymph nodes. All women receive combined endocrine treatment with ovarian suppression plus tamoxifen, and are randomised to receive in addition, either chemotherapy or no chemotherapy, to see if results differ.Read moreRead less

Summary
For women <50yrs with ER+ breast cancer adjuvant treatment (AT) with chemotherapy (CT), tamoxifen and ovarian function suppression (OFS) are each effective and reduce recurrence. Combining 2 treatments is more effective than 1, but it is unclear if combining 3 provides any extra benefit. 2 trials,SOFT and TEXT, aim to answer this question. SOFT tests the benefit of adding OFS for very young women who remain premenopausal after CT, TEXT is for women who should receive OFS from the start of AT.

Summary
This proposal is aimed at determining the three dimensional structure of Thyroid Peroxidase, a protein found in the human thyroid gland that is important in the production of the hormone thyroxine. Thyroxine is involved in controlling the rate of metabolic processes in the body and influencing physical development.
The Efficacy Of Adjunctive Garcinia Mangostana Linn. Pericarp For Bipolar Depression: A 24-week Double-blind, Randomized, Placebo-controlled Trial.

Summary
Bipolar disorder, especially during episodes of depression, can be highly debilitating. There is scientific evidence now directing research towards new targets to produce new therapies for bipolar depression. The current study aims to utilise an entirely new agent made from the husk of the mangosteen fruit (mangosteen pericarp). Mangosteen pericarp has properties that we believe will assist in reducing symptoms for those with bipolar depression, when taken in addition to usual treatment.

Summary
This application covers 4 adjuvant early breast cancer trials currently part of the Australian New Zealand Breast Cancer Trials Group's national research programme. These trials are international collaborations involving the International Breast Cancer Study Group (IBCSG). Two of the studies concern pre, peri and post-menopausal women with early breast cancer and no involved lymph glands (IBCSG 8 and 9), and two concern pre, peri and post-menopausal women with early breast cancer and involved ly ....This application covers 4 adjuvant early breast cancer trials currently part of the Australian New Zealand Breast Cancer Trials Group's national research programme. These trials are international collaborations involving the International Breast Cancer Study Group (IBCSG). Two of the studies concern pre, peri and post-menopausal women with early breast cancer and no involved lymph glands (IBCSG 8 and 9), and two concern pre, peri and post-menopausal women with early breast cancer and involved lymph glands (IBCSG 13 and 14). In the absence of a definitive cure, the largest gains will come from optimal use of current therapies and new therapies to improve survival, and where possible, to reduce morbidity without the loss of efficacy. These four trials can realistically expect to produce important gains with potential benefit to the many women who are diagnosed with early breast cancer each year. The active accrual period for these studies is complete but all patients are currently on life long follow-up. Patients accrued to trial 8 have a clinical assessment 3 monthly to 2 years, 6 monthly to 5 years, and then annually. For trials 9, 13 and 14 women have a clinical assessment 3 monthly during year 1, 6 monthly for year 2 and then annually.Read moreRead less

Lung cancer is the most common cause of cancer deaths in men and women in the world and the incidence in Australia is rising with our aging population. Survival rates for lung cancer are very poor. We have discovered a new gene that is produced by lung cancer cells and may contribute to the aggressive nature of this disease. We will investigate this gene to determine if it could be a useful target for new therapies for lung cancer and it determine its utility as a biomarker for the severity of t ....Lung cancer is the most common cause of cancer deaths in men and women in the world and the incidence in Australia is rising with our aging population.
