title: Granulocyte-macrophage colony-stimulating factor in patients with neutropenic fever is potent after low-risk but not after high-risk neutropenic chemotherapy regimens: results of a randomized phase III trial.
abstract: OBJECTIVE
  A randomized unblinded phase III trial was designed to determine the ability of granulocyte-macrophage colony-stimulating factor (GM-CSF) to accelerate recovery from febrile neutropenia induced by chemotherapy.
  
  
  METHODS
  A total of 68 patients with febrile neutropenia following chemotherapy defined as axillary temperature greater than 38 degrees C and absolute neutrophil count (ANC) less than 1 x 10(9)/L were included. After stratification for high- and low-risk chemotherapy to induce febrile neutropenia, treatment was randomized between GM-CSF at 5 microg/kg/d or control, both being associated with antibiotics.
  
  
  RESULTS
  GM-CSF significantly reduced the median duration of neutropenia from 6 to 3 days for ANC less than 1 x 10(9)/L(P < .001) and from 4 to 3 days for ANC less than 0.5 x 10(9)/L (P=.024), days of hospitalization required for febrile neutropenia, and duration of antibiotics during hospitalization. The greatest benefit with GM-CSF appeared for patients who had received low-risk chemotherapy, for which the median duration of ANC less than 1 x 10(9)/L was reduced from 7 to 2.5 days (P < .001) and from 4 to 2 days for ANC less than 0.5 x 10(9)/L (P=.0011), the duration of hospitalization during the study from 7 to 4 days (P=.003), and the duration on antibiotics during hospitalization from 7 to 3.5 days (P < .001). A multivariate analysis, using Cox regression, showed that variables predictive for recovery from neutropenia were GM-CSF (P=.0010) and time interval between the first day of chemotherapy and randomization (P=.030). There was no benefit for GM-CSF when high-risk chemotherapy was considered.
  
  
  CONCLUSIONS
  GM-CSF significantly shortened duration of neutropenia, duration of neutropenic fever-related hospitalization, and duration on antibiotics during hospitalization when febrile neutropenia occurred after low-risk chemotherapy, but not high-risk chemotherapy.
