574 Chapter 10: Graft Manipulation<br />

MATERIALS AND METHODS<br />

Patients<br />

Both groups, due to small numbers of patients, were heterogeneous with respect<br />

to sex <strong>and</strong> diagnosis. The historic group contained five males <strong>and</strong> 15 females, with<br />

16 solid tumor patients <strong>and</strong> four hematopoietic patients. The split reinfusion group<br />

contained five males <strong>and</strong> 21 females with 16 solid tumor patients <strong>and</strong> 10<br />

hematopoietic patients.<br />

Mobilization <strong>and</strong> leukapheresis<br />

All patients gave informed consent for peripheral stem cell (PSC) collection<br />

leukapheresis following st<strong>and</strong>ard induction chemotherapy, appropriate for their<br />

disease, followed by growth factor.<br />

Breast cancer patients received one of the following regimens: FAC: 5-<br />

fluorouracil, 500 mg/m 2<br />

, adriamycin, 50 mg/m 2<br />

, cyclophosphamide, 500 mg/m 2<br />

;<br />

CAVe: cyclophosphamide, 500 mg/m 2<br />

, adriamycin, 50 mg/m 2<br />

, etoposide, 240<br />

mg/m 2<br />

; CAT: cyclophosphamide, 500 mg/m 2<br />

, adriamycin, 50 mg/m 2<br />

, taxol, 175<br />

mg/m 2<br />

.<br />

Non-Hodgkin's lymphoma patients received one of the following regimens:<br />

CHOP: Cytoxan, 800 mg/m 2<br />

, adriamycin, 50 mg/m 2<br />

, vincristine, 2 mg; DHAP:<br />

Ara-C, 100 mg/m 2<br />

, Cytoxan, 90 mg/m 2<br />

.<br />

Myeloma patients received CVAD: Cytoxan, 1 gm/m 2<br />

, vincristine, 1.6 mg,<br />

adriamycin, 32 mg/m 2<br />

, dexamethasone, 160 mg.<br />

Growth factor support consisted of 5 pg/kg G-CSF (Amgen) beginning 2 days<br />

after completion of therapy <strong>and</strong> continuing through leukapheresis. Daily apheresis<br />

began when the total circulating CD34 +<br />

cell count exceeded 50 X10 6<br />

<strong>and</strong> continued<br />

until 4-5 X10 6<br />

CD34 +<br />

cells/kg had been collected. High-speed (85-110 mL/min)<br />

large volume (18-20 liters) procedures were performed on a Cobe Spectra (Cobe<br />

BCT) or Baxter CS3000 (Baxter Fenwal). A single sample was taken from the final<br />

product bag for total nucleated cell count, CD34 +<br />

analysis, <strong>and</strong> sterility testing.<br />

Progenitor cell processing <strong>and</strong> storage<br />

PSC products were platelet <strong>and</strong> plasma depleted. Cells were historically<br />

frozen based on the total nucleated cell count, 500-700 X10 6<br />

nucleated cells/mL,<br />

<strong>and</strong> are currently frozen based on CD34 +<br />

cell count with 2.0-2.5 X 10 6<br />

/kg in each<br />

bag. Bag volumes for both groups ranged between 40 <strong>and</strong> 70 mL <strong>and</strong> contained<br />

a final concentration of 10% DMSO <strong>and</strong> 10% cryoprecipitated <strong>autologous</strong><br />

plasma. All cells were frozen using a Cryomed rate-controlled freezing unit<br />

(Forma Scientific).
