ASCO updates guideline on CSFs

Red and white blood cells

The American Society of Clinical Oncology (ASCO) has updated its clinical practice guideline on hematopoietic colony-stimulating factors (CSFs).

The guideline includes recommendations on the use of CSFs in the context of lymphoma, solid tumor malignancies, pediatric leukemia, and hematopoietic stem cell transplant.

There are no recommendations pertaining to adults with acute myeloid leukemia or myelodysplastic syndromes.

ASCO’s previous guideline on CSFs was issued in 2006. For the update, an ASCO expert panel conducted a formal systematic review of relevant articles from the medical literature published from October 2005 through September 2014.

Key recommendations from the resulting guideline are as follows.

Pegfilgrastim, filgrastim, tbo-filgrastim, and filgrastim-sndz (and other biosimilars, as they become available) can be used for the prevention of treatment-related febrile neutropenia.

For patients with lymphomas or solid tumors, primary prophylaxis with a CSF should be given during all cycles of chemotherapy in patients who have an approximately 20% or higher risk for febrile neutropenia on the basis of patient-, disease-, and treatment-related factors.

However, clinicians should also consider using chemotherapy regimens that do not require CSF administration but are as effective as regimens that do require a CSF.

Patients with lymphomas or solid tumors should receive secondary febrile neutropenia prophylaxis with a CSF if they experienced a neutropenic complication from a previous cycle of chemotherapy (for which they did not receive primary prophylaxis) when a reduced dose or treatment delay may compromise disease-free survival, overall survival, or treatment outcome.

However, the guideline also says that, in many clinical situations, dose reductions or delays may be a reasonable alternative.

CSFs should not be routinely used for patients with neutropenia who are afebrile or as adjunctive treatment with antibiotic therapy for patients with fever and neutropenia.

Dose-dense regimens with CSF support should only be used within an appropriately designed clinical trial or if use of the regimen is supported by convincing efficacy data. The guideline says that, for non-Hodgkin lymphoma, data on the value of dose-dense regimens with CSF support are limited and conflicting.

In the context of transplant, CSFs may be used alone, after chemotherapy, or in combination with plerixafor to mobilize peripheral blood stem cells. To reduce the duration of severe neutropenia, CSFs should be administered after autologous stem cell transplant and may be administered after allogeneic stem cell transplant.

CSFs should be avoided in patients receiving concomitant chemotherapy and radiation, particularly involving the mediastinum. CSFs may be considered in patients receiving radiation alone if the clinician expects prolonged treatment delays due to neutropenia.

Patients who are exposed to lethal doses of total-body radiotherapy, but not doses high enough to lead to certain death resulting from injury to other organs, should promptly receive CSFs or pegylated granulocyte CSFs.

Clinicians should consider prophylactic CSF for patients with diffuse aggressive lymphoma who are 65 or older and are receiving curative chemotherapy (R-CHOP), particularly if they have comorbidities.

The guideline also says the use of CSFs in pediatric patients will almost always be guided by clinical protocols. But CSFs should not be used in pediatric patients with nonrelapsed acute lymphoblastic leukemia or nonrelapsed acute myeloid leukemia who do not have an infection.

For more details, see the complete guideline. ASCO said it encourages feedback on its guidelines from oncologists, practitioners, and patients through the ASCO Guidelines Wiki.
