Another study involving 33 lymphoma patients with at least one prior mobilization failure and receiving low dose cytarabine-based (400mg/m2/day×3 days) CM reported a mean CD34+ cell count of 4.69×106 (range: 1.5-6.8×106)/kg (23), whereas in our study, the PMs group had a mean count of 17.99×106/kg. The gene discussed is CD34; the disease is lymphoma.
