The use of G-CSF after the administration of chemotherapy may be in several settings:
- “Primary prophylaxis,” when neutropenia is expected to occur following a course of chemotherapy, but the patient has never experienced it.
- “Secondary prophylaxis,” when the patient had a neutropenic fever in a previous course of similar chemotherapy and is thus expected to do so again.
- “Supportive” in the attempt to shorten the duration of severe chemotherapy-induced neutropenia in patients without fever (“afebrile neutropenia”).(Freifeld AG, Bow EJ, Sepkowitz KA, et al. Clinical practice guideline for the use of antimicrobial agents in neutropenic patients with cancer: 2010 update by the Infectious Diseases Society of America. Clin Infect Dis. 2011;52:e56–e93. ).
Administration of G-CSF is generally not recommended for routine treatment in patients with established fever and neutropenia.
NCCN, ASCO and ASH guidelines recommend routine use of Neulasta® or Neupogen (filgrastim) for patients with an overall risk of FN of 20% or greater. Previous studies have suggested that prophylactic Neulasta can reduce the incidence of hospitalizations, decrease FN and allow better delivery of protocol doses of chemotherapy. The recommended dosage of Neulasta® is a single subcutaneous injection of 6 mg administered once per chemotherapy cycle. Neulasta® should not be administered in the period between 14 days before and 24 hours after administration of cytotoxic chemotherapy.
The supportive data was generated from 8 randomized clinical trials and 3 observational studies conducted between 1998 and 2005.

Some specific regimens.
The reported rates of febrile neutropenia differ between studies of the TC(Taxotere/Cytoxan) studies. The Jones et al study, noted a trend toward more febrile neutropenia (FN; 5% v 2.5%, P = .07) in the TC group. A 2009 study(Soong et al) reported FN rates of up to 50%. While true rates of FN are beign assessed, I consider Neulasta appropriate for the TC regimen.
A recent study(Vandenberg et al) found that patients older than 65 had a 40% risk of febrile neutropenia with the AC regimen.
Carboplatin/paclitaxel result in a very low incidence of grade 4 neutropenia

The recent 2005 ASCO guideline added that patients treated with palliative intent for metastatic disease should have thir dose reduced rather than use myeloid growth factors.

The prevalence of febrile neutropenia in this regimen was specifically looked at from a regulatory perspective. Historically, reported rates of FN without prophylactic G-CSF range from 5% in the phase III trial to as high as 50% in retrospective chart reviews for TC regimen. Guidelines recommend GCSF propjylaxis when febrile neutropenia exceeds 20%. As G-CSF was not covered by Ontario provincial cancer funding agency for primary prophylaxis of FN with TC chemotherapy, local investigators sought to determine the incidence of FN with TC chemotherapy in two comprehensive cancer centres in Ontario, Canada. Methods: Patients who received adjuvant TC chemotherapy between January 1, 2008 and December 31, 2012 were identified through the pharmacy databases. Electronic charts were retrospectively reviewed to abstract patient characteristics, treatment details including G-CSF use, and incidence of FN. : Preliminary results from one institution demonstrate that 187 patients were treated with TC over the study period. Of the 74 (40%) patients who did not receive primary G-CSF prophylaxis, 23 (31%) developed FN requiring hospitalization and treatment with intravenous antibiotics. However, none of the 113 patients who received primary G-CSF prophylaxis (funded by the patient or a third party payer) developed FN. Putative risk factors for FN in the absence of G-CSF including age, BSA, BMI, and pre-treatment absolute neutrophil count were examined and will be reported. Conclusions: The FN rate associated with TC chemotherapy exceeds 30%, higher than that reported in the clinical trial. They concluded: As per ASCO guidelines, primary G-CSF prophylaxis should be given with TC chemotherapy, and in Canada this should be covered by provincial cancer funding agencies.
