American Society of Clinical Oncology. Recommendations for the use of hematopoietic colony-stimulating factors: evidence-based, clinical practice guidelines
PURPOSE: Standard practice in protecting against chemotherapy- associated
infection has been chemotherapy dose modification or dose delay,
administration of progenitor-cell support, or selective use of prophylactic
antibiotics. Therapy of chemotherapy-associated neutropenic fever or
infection has customarily involved treatment with intravenous antibiotics,
usually accompanied by hospitalization. The hematopoietic
colony-stimulating factors (CSFs) have been introduced into clinical
practice as additional supportive measures that can reduce the likelihood
of neutropenic complications due to chemotherapy. Clinical benefit has been
shown, but the high cost of CSFs has led to concern about their appropriate
use. The American Society of Clinical Oncology (ASCO) wishes to establish
evidence-based, clinical practice guidelines for the use of CSFs in
patients who are not enrolled on clinical trials. METHODS: An expert
multidisciplinary panel reviewed the clinical data documenting the activity
of CSFs. For each common clinical situation, the Panel formulated a
guideline to encourage reasonable use of CSFs to preserve effectiveness but
discourage excess use when little marginal benefit is anticipated.
Consensus was reached after critically appraising the available evidence.
Guidelines were validated by comparing them with recommendations for CSF
use developed in other countries and by several academic institutions.
Outcomes considered in evaluating CSF benefit included duration of
neutropenia, incidence of febrile neutropenia, incidence and duration of
antibiotic use, frequency and duration of hospitalization, infectious
mortality, chemotherapy dose-intensity, chemotherapy efficacy, quality of
life, CSF toxicity, and economic impact. To the extent that these data were
available, the Panel placed greatest value on survival benefit, reduction
in rates of febrile neutropenia, decreased hospitalization, and reduced
costs. Lesser value was placed on alterations in absolute neutrophil counts
(ANC). CONCLUSIONS: CSFs are recommended in some situations, eg, to reduce
the likelihood of febrile neutropenia when the expected incidence is >
or = 40%; after documented febrile neutropenia in a prior chemotherapy
cycle to avoid infectious complications and maintain dose-intensity in
subsequent treatment cycles when chemotherapy dose-reduction is not
appropriate; and after high-dose chemotherapy with autologous
progenitor-cell transplantation. CSFs are also effective in the
mobilization of peripheral-blood progenitor cells. Therapeutic initiation
of CSFs in addition to antibiotics at the onset of febrile neutropenia
should be reserved for patients at high risk for septic complications. CSF
use in patients with myelodysplastic syndromes may be reasonable if they
are experiencing neutropenic infections. Administration of CSFs after
initial chemotherapy for acute myeloid leukemia does not appear to be
detrimental, but clinical benefit has been variable and caution is advised.
Available data support use of CSFs in pediatric cancer patients similar to
that recommended for adult patients. Outside of clinical trials, CSFs
should not be used concurrently with chemotherapy and radiation, or to
support increasing chemotherapy dose-intensity. Further research is
warranted as a means to improve the cost-effective administration of the
CSFs and identify clinical predictors of infectious complications that may
direct their use.
