Economic impact of granulopoiesis stimulating agents on the management of febrile neutropenia

Abstract

The granulopoiesis-stimulating agents (GSAs) have been effectively utilized in a variety of fashions to treat or prevent febrile neutropenia or to assist patients receiving dose-intensive chemotherapy with or without stem cell support. The high cost of these agents, along with their wide-scale clinical application, has fostered a number of economic analyses. Cost minimization models based on randomized trials and driven by hospitalization costs have provided febrile neutropenia risk thresholds for the use of the GSAs which have been incorporated into clinical practice guidelines. A number of important studies concerning the clinical and economic impact of these agents have been reported over the past year. The clinical role and economic impact of the GSAs in the management of either established febrile neutropenia or afebrile neutropenia remains uncertain. While several studies have confirmed the clinical value of the prophylactic use of these agents in both solid tumors and hematological malignancies, few have addressed their effect on cost or quality of life. The GSAs have demonstrated clinical as well as potential economic benefit in patients receiving high-dose chemotherapy with either bone marrow or peripheral blood stem cell support. Recent studies suggest a clinical and economic advantage for growth factor mobilization and peripheral blood stem cell support compared with bone marrow transplantation in patients receiving high-dose chemotherapy. The rapid evolution of technological and supportive care methods in this area will necessitate further clinical and economic evaluation.
