title: Effect of granulocyte colony-stimulating factor in patients with diffuse large cell lymphoma treated with intensive chemotherapy.
abstract: We investigated whether Granulocyte colony-stimulating factor (G-CSF) could prevent myelotoxicity or accelerate hematopoietic recovery after intensive chemotherapy in previously untreated patients with diffuse large cell lymphoma (DLCL). Forty-two patients were included in a prospective clinical trial in which alternating chemotherapy ESAP (etoposide, Solu-Medrol, cytosine arabinoside, cis-platinum), m-BECOD (low doses methotrexate, bleomycin, epirubicin, cyclophosphamide, vincristine, dexamethasone), MVPP-Bleo (mitoxantrone, vincristine, prednisone, procarbazine, bleomycin) were administered by 9 cycles. Each cycle was followed by 10 days of G-CSF (5 micrograms/kg/day) started five days after chemotherapy compared to a control group which received chemotherapy without G-CSF support. Leucocytes and granulocytes were significantly higher in patients receiving G-CSF compared to the control group. The total number of days of leukopenia (WBC counts below 2.0 x 10(9)/L and absolute granulocytes below 1.0 x 10(9)/L) were longer in the patients without G-CSF compared to those who received G-CSF (14.1 days versus 1.9 days). Delays in treatment were most frequent in the control group: 38% versus 4% in all cycles. Infection episodes occurred in 41 out of 168 cycles (25%) in the control group compared to 7 out of 172 (4%) in the G-CSF arm. Complete response was achieved in 12 out of 22 (54%) in the control group compared to 16 out 20 (80%) in the patients who received G-CSF. Toxicity secondary to G-CSF was mild. G-CSF can be administered safely to patients with DLCL and results in improved hematologic recovery after intensive chemotherapy.(ABSTRACT TRUNCATED AT 250 WORDS)
