From the FDA Drug Label
ZARXIO is a leukocyte growth factor indicated to • Decrease the incidence of infection‚ as manifested by febrile neutropenia‚ in patients with nonmyeloid malignancies receiving myelosuppressive anti‑cancer drugs associated with a significant incidence of severe neutropenia with fever (1. 1)
DOSAGE AND ADMINISTRATION • Patients with cancer receiving myelosuppressive chemotherapy or induction and/or consolidation chemotherapy for AML o Recommended starting dose is 5 mcg/kg/day subcutaneous injection, short intravenous infusion (15 to 30 minutes), or continuous intravenous infusion.
The management of bandemia in cancer patients involves the use of filgrastim to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with nonmyeloid malignancies receiving myelosuppressive anti-cancer drugs. The recommended starting dose is 5 mcg/kg/day subcutaneous injection, short intravenous infusion, or continuous intravenous infusion. 1
From the Research
Bandemia in cancer patients should be managed with prompt evaluation and treatment of the underlying cause, typically infection, using empiric broad-spectrum antibiotics and supportive care, as it is a significant predictor of bacteremia and sepsis, as shown in a recent study 2.
Management of Bandemia
The management of bandemia in cancer patients involves several key steps:
- Obtaining blood cultures, urine cultures, and imaging studies to identify the source of infection
- Administering empiric broad-spectrum antibiotics such as piperacillin-tazobactam, meropenem, or cefepime plus vancomycin for neutropenic patients
- Providing supportive care, including maintaining hydration, monitoring vital signs, and administering antipyretics for fever
- Considering the use of granulocyte colony-stimulating factors (G-CSF) like filgrastim to stimulate neutrophil production in severe cases
Importance of Bandemia
Bandemia is a significant predictor of bacteremia and sepsis in cancer patients, as shown in a recent study 2, which found that bandemia was associated with a higher incidence of bacteremia and had a sensitivity and specificity of 0.42 and 0.91, respectively, for predicting bacteremia.
Treatment Duration
The treatment duration for bandemia in cancer patients depends on the clinical response, culture results, and resolution of bandemia, typically ranging from 7-14 days for documented infections.
Monitoring
Regular complete blood count monitoring is essential to track the patient's response to treatment and adjust therapy accordingly.
Recent Evidence
A recent study 3 found that early trends of serum band levels in patients with sepsis or septic shock may help predict clinical trajectory and overall prognosis, highlighting the importance of monitoring bandemia in cancer patients.
Clinical Decision-Making
The use of bandemia trends, in conjunction with other known markers such as lactate levels, may help guide bedside clinical decisions, including risk stratification, tailored therapies, and ultimately improve outcomes, as suggested by a study 3.
