CSF3 and Miyoshi myopathy: We further analyzed the 13 patients (4 MM and 9 lymphoma patients) who were truly poor mobilizers and failed to collect ≥2 × 106 CD34+ cells/kg during the first mobilization with G-CSF only, thus excluding the myeloma patients who were defined as poor mobilizers based on their failure to collect ≥4 × 106 CD34+ cells/kg for two transplants.
