230 Chapter 5: Myeloma<br />

two groups are well balanced in regard to the initial characteristics, the response to<br />

initial CC, <strong>and</strong> the modalities of PB PC collection. The only differences between the<br />

two groups were the median number of CD34 +<br />

cells in the graft, which was slightly<br />

higher in the HDM 200 mg/m 2<br />

group (8.5X 10 6<br />

/kg vs. 6X 10 6<br />

/kg, /»=0.08), <strong>and</strong> the<br />

number of patients receiving growth factors after <strong>transplantation</strong> (78% in the total<br />

body irradiation group vs. 96% in the HDM200 group, f=0.008). Currently, there<br />

is no significant difference in clinical outcome between the two groups (Table 2).<br />

However, HDM 200 mg/m 2<br />

appears to be less toxic. The median duration of<br />

neutropenia is significantly shorter (8 vs. 10 days, /°3 mucositis is dramatically reduced after HDM 200<br />

mg/m 2<br />

(3 vs. 52%).<br />

If these results are confirmed by further analysis, HDM 200 mg/m 2<br />

should be<br />

preferred to the st<strong>and</strong>ard regimen HDM 140 mg/m 2<br />

plus total body irradiation,<br />

since this regimen has similar efficacy but is easier to perform <strong>and</strong> is, apparently,<br />

less toxic.<br />
