Disease-Free Survival for Patients Transplanted in R1<br />

Months Post ABMT<br />

Figure 5<br />

underwent autoBMT with supplemental PBSCT. Each engrafted neutrophils at a<br />

median time of 13 days (11-23 days). Two patients have relapsed at 8 <strong>and</strong> 14<br />

months posttransplant in CR2.<br />

Three additional patients were infused with cells first purified with the CellPro<br />

CEPRATE column to isolate CD34 +<br />

cells followed by PM-81 mAb plus<br />

complement. Three patients (one in CR1, one in CR2, <strong>and</strong> one in second relapse)<br />

have been treated with this purging method. Median time to neutrophil recovery<br />

was 21 days.<br />

DISCUSSION<br />

Bone <strong>marrow</strong> <strong>transplantation</strong> offers the potential for complete elimination of<br />

occult leukemia cells after initial remission induction <strong>and</strong> is probably the only<br />

curative treatment for patients with AML after first relapse. 4<br />

Allogeneic BMT is<br />

established as a potentially curative therapy for patients in first remission, but the<br />

majority of patients with AML cannot undergo this therapy due to lack of an HLAmatched<br />

donor or advanced age. 4<br />

This report <strong>and</strong> others 5-18<br />

show that autoBMT is<br />

a viable alternative.
