Abstract
Diffuse large B-cell lymphoma is the most prevalent form of non-Hodgkin's lymphoma that is usually treated with chemoimmunotherapy. If the disease proves refractory or recurrent, the primary treatment approach involves high-dose chemotherapy with bone marrow transplantation. The collection of peripheral blood stem cells before transplantation plays a vital role in the treatment process, necessitating the mobilization of blood stem cells from the bone marrow to the peripheral blood. Despite using standard methods such as granulocyte colony-stimulating factor (G-CSF), chemotherapy, and plerixafor, some patients cannot collect an optimal count of CD34+ cells for transplantation. Managing these patients with poor mobilization poses significant challenges. In this article, we present a case of a poor mobilizer patient who achieved prosperous mobilization by using recombinant human G-CSF, recombinant human growth hormone, and plerixafor.
