Summary
This project is testing the use of a drug docetaxel in the post-operative (adjuvant) treatment of women with breast cancer and involved lymph nodes (N+). Until recently the drug doxorubicin was the most active chemotherapy drug for breast cancer, but more recently a new group of chemotherapy drugs called taxanes were identified. One taxane called docetaxel may be even more effective than doxoubicin.

Until recently the drug doxorubicin was the most active chemotherapy drug for breast cancer, but more recently a new group of chemotherapy drugs called taxanes were identified. One taxane called docetaxel may be even more effective than doxoubicin. Using available treatments that include doxorubicin based chemotherapy, approximately half the women with N+ breast cancer experience recurrence of their cancer. It is therefore important to test whether the inclusion of docetaxel in adjuvant therapy can reduce relapses. If docetaxel is to be included, it is also important to test whether it is best to combine it with doxorubicin at the same time (which for safety reasons requires the doses of each drug to be reduced), versus giving them sequentially at full dose. Currently, docetaxel is not approved nor funded for use in early breast cancer in Australia. There are several international trials testing the inclusion of taxanes in the adjuvant therapy of breast cancer. However this trial stands out, because all the women in the trial receive chemotherapy of at least 6 months. In some other trials, testing the possible benefit of adding a taxane, women in the control treatment group (who were randomised not to receive the taxane) received only 3 months of treatment, which makes it difficult to distinguish between longer treatment or addition of the taxane drug. This trial has completed international recruitment of 2890 women who will be carefully followed for 10 years. Australian and New Zealand centers recruited 20% of the women in the trial. After the women have been followed-up for 5 years the results of this trial will be analysed, presented and published and should provide reliable evidence about the potential benefit of adding docetaxel into adjuvant chemotherapy.Read moreRead less

Summary
This project is investigating the optimal use of docetaxel and doxorubicin in the treatment of women with breast cancer and involved lymph nodes (N+). Every year 3000 women in Australia, and over 400,000 worldwide are newly diagnosed with N+ breast cancer. Using available treatments more than 60% of these (5 per day in Australia, 4,500 each week worldwide) will die from breast cancer.

Every year 3000 women in Australia, and over 400,000 worldwide are newly diagnosed with N+ breast cancer. Using available treatments more than 60% of these (5 per day in Australia, 4,500 each week worldwide) will die from breast cancer. The efficacy of adjuvant chemotherapy in early breast cancer is well established by the international overview conducted by the Early Breast Cancer Trialist's Collaborative Group (EBCTCG). They have demonstrated the efficacy of adjuvant chemotherapy on reducing mortality and recurrence rates, but current regimens are far from optimal. Docetaxel (Taxotere), a new agent, has effectiveness and manageable side effects in the treatment of advanced breast cancer patients, and can plausibly improve outcomes for patients with early N+ breast cancer by optimal integration into current adjuvant chemotherapy regimens. This clinical trial is designed to compare whether it is advantageous to use docetaxel and-or doxorubicin in combination or sequentially with other currently available chemotherapy drugs.Read moreRead less
