G-CSF after autologous hemopoietic stem cell transplantation in malignant lymphoma

Forty-eight autografted patients were studied after treatment with granulocyte-colony stimulating factor (G-CSF) and were compared with a historical series of 24 patients autografted with bone marrow (BM) without G-CSF. When the patients were divided on the basis of G-CSF administration, type of lymphoma and the source of hemopoietic stem cells, no significant difference was found in the median number of infused BM cells, duration of febrile episodes, platelet and hemoglobin recovery, or in the number of transfusions. The patients receiving peripheral blood (PB) + G-CSF had significantly shorter median durations of antibiotic therapy, hospital stay and polymorphonucleate (PMN) recovery. When the Hodgkin disease (HD) and non-Hodgkin lymphoma (NHL) cases were considered separately, a significant difference between those receiving and those not receiving G-CSF was observed only in the HD group. The advantage offered by PB + G-CSF over BM + G-CSF was far more evident in the NHL group than in HD. It can be concluded that G-CSF improves the outcome of BM transplant in HD, and that the use of PB + G-CSF adds a further advantage; conversely, in NHL, PB + G-CSF is strikingly superior to BM + G-CSF, but the addition of G-CSF adds little advantage.
