Thirty-four adults with refractory acute lymphocytic leukemia received salvage therapy with mitoxantrone 5 mg/m2 intravenously over 1 hour daily for 5 days and cytosine arabinoside (ara-C) 3 g/m2 intravenously over 2 hours every 12 hours for six doses, followed by granulocyte-macrophage colony-stimulating factor (GM-CSF) 125 microgram/m2 intravenously over 4 hours daily until recovery of granulocytes above 2.0 x 10(3)/microL. Their outcome was compared with 29 prognostically similar historical control patients treated with the identical chemotherapy without GM-CSF. Overall, the complete response rates were similar in the treatment and control groups (13 of 34 [38%] v 11 of 29 [38%]). There was a trend for less remission induction mortality in the GM-CSF-treated patients (2 of 34 [6%] v 6 of 29 [21%]; P = .08), but, conversely, a higher rate of resistant disease (19 of 34 [56%] v 10 of 29 [34%]; P = .09). Recovery of granulocyte counts above 500/microL was significantly faster in the GM-CSF-treated group (25 days v 33 days; P less than .01), but there was no reduction in the incidence of febrile episodes (91% v 93%) or of documented infections (59% v 59%). Survival was prolonged in the GM-CSF-treated patients but was not of clinical relevance (31 v 20 weeks; P = .05). In summary, the addition of GM-CSF to intensive chemotherapy in refractory adult ALL was associated with a reduction in the remission induction mortality, probably secondary to a shorter duration of granulocytopenia, but not with an improvement in complete response rates.

We quantitatively assessed the expression of cytokine receptors (interleukin-2 receptor (IL-2R), IL-3R, IL-4R, IL-5R, IL-6R, IL-7R, granulocyte-macrophage colony-stimulating factor R (GM-CSFR), G-CSFR, c-fms, c-mpl, c-kit and FLT3) in cells from 211 adults with acute lymphoblastic leukemia (ALL) by flow cytometry and determined their prevalence and clinical significance. Although all cytokine receptors were expressed to various degrees, the levels of IL-3R alpha-chain (IL-3Ralpha), IL-2Ralpha, IL-2Rbeta, IL-7Ralpha, common-Rgamma(gammac), c-mpl, c-kit and FLT3 exhibited a wide spectrum > or =2000 sites/cell. Among them, IL-3Ralpha, IL-2Ralpha and FLT3 were highly expressed in B-lineage ALL, whereas IL-7Ralpha, gammac and c-kit predominated in T-lineage ALL. Higher levels of IL-3Ralpha, IL-2Ralpha, c-kit and FLT3 correlated with the expression of CD13/33. Increased IL-2Ralpha levels related to the presence of Philadelphia chromosome (Ph), leukocytosis and shorter event-free survival (EFS). C-kit preferred in male. Elevated FLT3 levels correlated with age > or =60 years. Multivariate analysis in B-lineage ALL revealed only IL-2Ralpha (P=0.028) and Ph (P=0.020) as independent factors for EFS. These findings suggest that several cytokine receptors associated with certain cellular and clinical features, but IL-2Ralpha solely had a prognostic value and should be considered as a major prognostic factor for adult ALL that is comparable with Ph.

The capacity to generate effective dendritic cells (DC) from adult acute lymphoblastic leukemia (ALL) patients in complete remission (CR) and off-therapy was investigated. Monocyte-derived DC cultured in the presence of granulocyte-macrophage colony-stimulating factor, interleukin (IL)-4 and tumor necrosis factor (TNF)-alpha expressed maturation markers, produced IL-12 and loaded apoptotic bodies to a similar extent to normal DC. Patients' circulating T and NK lymphocytes were normally represented and, after stimulation, were capable of producing TNF-alpha and interferon-gamma to a similar extent to control lymphocytes. DC loaded with leukemia-derived apoptotic bodies increased their ability to stimulate both allogeneic and autologous lymphocytes, and to generate specific anti-leukemic CD3 + cells. These findings offer a rationale for the design of DC-based vaccine programs for adult ALL patients in CR with the aim of controlling/eradicating the disease.
