title: Role of granulocyte colony stimulating factor (G-CSF) in chemotherapy induced neutropenia.
abstract: BACKGROUND
  In the past decade, there have been many clinical trials investigating the potential benefits of adjunctive therapy with colony stimulating factors (CSFs) both to ameliorate or prevent profound neutropenia and its potentially life threatening consequences. Neutropenia is the most common dose limiting side effects of cytotoxic chemotherapy. We decided to study the effect of same in our patients coming to haematology clinic.
  
  
  OBJECTIVE
  To see the effect of G-CSF on severity of neutropenia following chemotherapy in patients of haematological malignancies and to see the effect of G-CSF on duration of hospitalization, documented infections and duration of fever as compared to control group in patients with neutropenia following chemotherapy in haematological malignancies.
  
  
  METHODS
  Thirty patients of acute leukemia were prospectively studied. Patients were given G-CSF 24.hours following chemotherapy induced neutropenia and following parameters were observed. (a) median time to ANC recovery (b) incidence and duration of fever (c) duration of hospitalization following chemotherapy (d) incidence of documented infections. The patients were given G-CSF until the neutrophil count was >1000/ml for 3 days or maximum of 7 days.
  
  
  RESULTS
  Mean age was 29.33 +/- 14 years in G-CSF group and 27.53 +/- 13.75 in control group. Mean duration of neutropenia was 11.4 days (p < 0.05) in G-CSF group and 15.8 days in control group. Mean duration of fever was 8.2 days in G-CSF group and 13.53 days in control group (p < 0.05). Mean duration of hospital stay was 21.33 days in G-CSF group and 25 days in control group (p > 0.05).
  
  
  CONCLUSIONS
  The study demonstrates that G-CSF administration is efficacious in chemotherapy induced neutropenia by decreasing the duration of neutropenia and duration of fever.
