title: Marrow storage techniques: a clinical comparison of refrigeration versus cryopreservation.
abstract: Fifty-three patients were evaluated for a comparison of the efficacy, safety, and cost efficiency of bone marrow (BM) transplanted after either refrigeration or cryopreservation. Thirty-eight patients had BM stored at 4 degrees C for an average of 3 days and 15 patients had cryopreserved BM stored for an average of 56 days. The average number of cells harvested was 3.8 x 10(8)/kg. The time to WBC recovery greater than 1 x 10(9)/l was 17 days refrigerated and 23 days for cryopreserved BM. The time to platelet recovery greater than 20 x 10(9)/l was 24 days for refrigeration storage and 51 days for cryopreserved BM. Four of 38 patients with refrigerated vs. 4/15 patients with cryopreserved BM experienced delayed engraftment (p less than 0.05). Refrigeration storage requires no special equipment, is cheaper than and presents a safe and viable alternative to cryopreserved BM in reconstituting hemopoiesis following high-dose chemo-radiotherapy.
