A retrospective analysis of patients with NHL (n = 238) or multiple myeloma (n = 602) who underwent mobilization with chemotherapy followed by G-CSF found no effect of body weight, sex, age, or previous irradiation therapy on the incidence of poor mobilization, whereas the total number of previous chemotherapy cycles did have a significant impact [16]. This evidence concerns the gene CSF3 and non-Hodgkin lymphoma.
