Similar outcomes have also recently been reported by the ABMTR. 1<br />

After a<br />

period of early phase II studies, in the last few years some r<strong>and</strong>omized phase III<br />

trials have been launched. The first, PEGASE 03 from the French National Group<br />

compares four courses of 5-fluorouracil, epirubicin, cyclophosphamide (FEC) with<br />

epirubicin delivered at the dose of 100 mg/m 2<br />

vs. the same FEC schedule followed<br />

by an intensification of high-dose cyclophosphamide (6 g/m 2<br />

) <strong>and</strong> thiotepa 800<br />

mg/m 2<br />

. This study, chaired by Dr. Pierre Biron in Lyon, stopped accrual at the end<br />

of 1998 (240 patients).<br />

In 1996, a Belgian study set up by Dr. Martine Piccart employed docetaxel<br />

upfront at the dose of 100 mg/m 2<br />

<strong>and</strong> then r<strong>and</strong>omization to another course of<br />

docetaxel followed by four courses of adriamycin 60 mg/m 2<br />

<strong>and</strong> cyclophos­<br />

phamide 600 mg/m 2<br />

or to docetaxel with lenograstim with the intent to mobilize<br />

PBPC, followed by two cycles of melphalan, 140 mg/m 2<br />

, <strong>and</strong> mitoxantrone, 35<br />

mg/m 2<br />

. The most recent proposal has come from a joint venture of the EBMT Solid<br />

Tumors Working Party <strong>and</strong> the European Breast Dose Intensity Study (EBDIS) <strong>and</strong><br />

the result is the EBDIS 1 trial chaired by Dr. John Crown in Dublin. Figure 4 shows<br />

the diagram of the trial. Two hundred sixty-four patients are expected to enter by<br />

the year 2000. After successful treatment with high-dose sequential chemotherapy<br />

of very high-risk operable breast cancer by the Milan group 3<br />

in patients with 10 or<br />

more positive axillary nodes, an Italian Cooperative Group recently started a<br />

similar program in naive patients with metastatic disease <strong>and</strong> good performance
