Expanding the Options for Risk-based Therapy in Febrile Neutropenia

Abstract

Fever in neutropenic cancer patients is often due to the development of an infection. The standard management of febrile neutropenic patients involves the administration of empiric, hospital-based, parenteral antibiotic therapy. Although this treatment strategy has evolved from experience in high-risk patients with hematological malignancies, in whom bacterial infection can result in substantial morbidity and mortality, it has been adopted for all patients with febrile neutropenia, largely because of the inability of clinicians to reliably distinguish between patients who are at high risk for developing such morbidity/mortality and those who are not. The development of risk-assessment models has facilitated the recognition of high-, moderate-, and low-risk subgroups among febrile neutropenic patients and allows the administration of outpatient antibiotic therapy to the moderate- and low-risk groups, with the same degree of efficacy and safety as hospital-based therapy. Monotherapy with the carbapenems (imipenem/cilastatin and meropenem), with their broad spectrum of activity and established efficacy in high-risk patients, represents realistic options for risk-based treatment of febrile neutropenic patients within and outside the hospital setting.
