Many factors identify patients at risk for febrile neutropenia

  Research to date has identified a number of factors that predict a patient’s risk for neutropenic events:20,21
     
Increasing age
Poor performance status
Advanced cancer
Bone marrow involvement
Comorbid disease
Active tissue infection
History of recurrent chemotherapy-induced neutropenia
Low serum albumin (non-Hodgkin’s lymphoma)
High lactate dehydrogenase (non-Hodgkin’s lymphoma)

Preexisting neutropenia:
- Prior myelosuppressive therapy
- Radiation therapy to bone marrow

 
A nationwide prospective registry of cancer patients is adding new data on the importance of patient risk factors in assessing the risk of febrile neutropenia.2,22
 
 

In a multivariate analysis, after adjustment for cancer type, age, baseline platelet, neutrophil, and lymphocyte counts, type of chemotherapy (anthracycline based or not), and primary prophylaxis, the following emerged as significant independent predictors of severe or febrile neutropenia in the first cycle of chemotherapy:22

  Important: Neulasta® is indicated in myelosuppressive chemotherapy regimens associated with a febrile neutropenia risk of at least 17%.
