Several randomised comparative trials have shown that granulocyte colony-stimulating factor (G-CSF) reduces the duration of neutropenia, hospitalisation and intravenous antibacterial use in patients with cancer who are receiving high-dosage antineoplastic therapy. However, one area that has received less attention is the role of G-CSF in standard-dosage antineoplastic regimens. One such treatment that is considered to have a low potential for inducing fever and neutropenia is the CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisone) for non-Hodgkin’s lymphoma.

We conducted a cost-benefit analysis from a societal perspective in order to estimate the net cost or benefit of prophylactic G-CSF in this patient population. This included direct costs for hospitalisation with antibacterial support, as well as indirect societal costs, such as time off work and antineoplastic therapy delays secondary to neutropenia. The findings were then tested by a comprehensive sensitivity analysis.

The administration of G-CSF at a dosage of 5 µg/kg/day for 11 doses following CHOP resulted in an overall net cost of $Can1257. In the sensitivity analysis, lowering the G-CSF dosage to 2 µg/kg/day generated a net benefit of $Can6564, indicating a situation that was cost saving to society.

The results of the current study suggest that the use of G-CSF in patients receiving CHOP antineoplastic therapy produces a situation that is close to achieving cost neutrality. However, low-dosage (2 µg/kg/day) G-CSF is an economically attractive treatment strategy because it may result in overall savings to society.
