WBC Growth Factors: ASCO Guideline Update

Prophylactic use of CSFs to reduce the risk of febrile neutropenia is warranted when the risk of febrile neutropenia from chemotherapy is approximately 20% or higher and no other equally effective and safe regimen that does not require CSFs is available. For patients receiving chemotherapy with a <20% risk of febrile neutropenia, primary prophylaxis with a CSF may be warranted if patients are at a high risk of febrile neutropenia based on age, medical history, or disease characteristics. For stem-cell mobilization, CSFs may be used either alone, after chemotherapy, or in combination with plerixafor or motixafortide. The guideline also provides information about the dosing and selection of CSFs.Additional information is available at www.asco.org/supportive-care-guidelines.
