Autologous peripheral blood stem cells were frozen in two origen cryostor freezing bags.The cells were frozen with cryoprotectant in controlled rate freeze and placed in a vapor phase liquid nitrogen storage container until day of transplant.Upon removal of patient's autologous stem cell product bags from frozen storage a large crack across the face of one of the bags was observed.Due to the potential risk of contamination it was determined by patient's medical staff that the product should not be infused into the patient.
