Effects of recombinant granulocyte colony-stimulating factor (G-CSF) in patients treated with ProMACE-CytaBOM for HIV-related non-Hodgkin's lymphoma (NHL).
OBJECTIVE
The use of hematopoietic growth factors in association with chemotherapy in human immunodeficiency virus (HIV)-related non-Hodgkin's lymphoma (NHL) has been recommended, but few studies have evaluated its cost-effectiveness.


METHODS
The effects of recombinant granulocyte colony-stimulating factor (G-CSF) were analyzed in 33 consecutive patients with HIV-related NHL treated at a single institution with the same chemotherapy program, ProMACE-CytaBOM, with G-CSF, in 21 cases diagnosed after December 31, 1991, or without G-CSF, in 12 cases diagnosed earlier. Pearson's chi-square analysis and the two-sided Student's t-test were used for statistical comparisons. The method of Kaplan-Meyer and the log-rank-test were used for survival analyses.


RESULTS
G-CSF support significantly reduced the frequency of day-1 drug dose reductions (p < 0.001) and of chemotherapy delays (p < 0.001), and improved the actual delivered doses of adriamycin, cyclophosphamide and etoposide (p < 0.02). In patients with a CD4+ count < 0.01 x 10(9)/L, chemotherapy could be given at full doses in 90% of cycles with G-CSF compared to only 20% without it. G-CSF affected neither the frequency and duration of fever and hospitalization nor the complete remission and survival rates after stratification according to the CD4+ count.


CONCLUSIONS
G-CSF support significantly improved dose-intensity in patients with HIV-related NHL treated with aggressive chemotherapy, particularly in the subgroup with a CD4+ count < 0.1 x 10(9)/L, but it did not improve their clinical outcome.
