- Harvest: Patients who achieve CR and are ineligible for allogeneic PBSC transplantation receive filgrastim (G-CSF) subcutaneously (SQ) every 12 hours beginning 20 days after starting consolidation treatment and continuing until autologous PBSC are harvested. Autologous bone marrow is collected from patients with insufficient PBSC. Allogeneic PBSC are harvested for patients who have an HLA identical donor. Allogeneic bone marrow is harvested for high risk patients (under age 40) who have an unrelated bone marrow donor.
