anthracycline or taxane based induction chemotherapy". 12<br />

Women with evidence of<br />

metastatic breast cancer who have not received chemotherapy for their<br />

metastatic/recurrent disease are eligible for the study. Women must have complete or<br />

partial responses to induction chemotherapy or have no évaluable disease. Each<br />

patient will receive either four cycles of anthracycline-based chemotherapy or, for<br />

patients who have prior anthracycline exposure, four cycles of paclitaxel- or<br />

docetaxel-containing regimen. After four cycles of induction chemotherapy, patients<br />

will be evaluated <strong>and</strong> the responders will be r<strong>and</strong>omized to either high-dose<br />

chemotherapy <strong>and</strong> <strong>autologous</strong> peripheral <strong>blood</strong> stem cell therapy or st<strong>and</strong>ard therapy.<br />

The st<strong>and</strong>ard arm includes at least two cycles of the same induction chemotherapy<br />

followed by maintenance therapy at the discretion of the investigator. The high-dose<br />

arm consists of a further two cycles of induction chemotherapy in conjunction with<br />

hematopoietic growth factors to harvest sufficient numbers of <strong>blood</strong> stem cells. If the<br />

response is confirmed after these two additional cycles, high-dose chemotherapy<br />

consisting of 6 g/m 2<br />

cyclophosphamide, 70 g/m 2<br />

mitoxantrone, 1800 mg/m 2<br />

CBCDA<br />

will be delivered in four equal doses on four consecutive days. Forty-eight hours later,<br />

the previously harvested stem cell products will be reinfused into the patient. The<br />

patients on this arm will not receive further chemotherapy. Hormonal intervention is<br />

left up to the discretion of the primary physician. The objectives of this trial are to<br />

compare overall survival, the final response rates, <strong>and</strong> treatment toxicity. Further<br />

objectives include a comparison of health-related quality of life. It is anticipated that<br />

400 patients will be enrolled within 4 years from the date of activation, ~200 of them<br />

r<strong>and</strong>omized. The study was activated in more than 25 centers across Canada <strong>and</strong>, as<br />

of December 1998, more than 200 patients have been enrolled.<br />
