The objective of this study was to evaluate the cost-effectiveness of pegfilgrastim (Peg-G) and daily filgrastim (Fil-G) for the primary prophylaxis against febrile neutropenia (FN) in patients with non-Hodgkin lymphoma (NHL) who received cyclophosphamide, vincristine, doxorubicin and prednisolone (CHOP) therapy. We developed a decision analytical model reflecting the clinical processes of NHL patients who received first CHOP therapy. The probabilities at each clinical endpoint were obtained
... m published sources. To estimate the costs and duration of FN treatment, we analyzed the medical records of NHL patients in hospitals participating in this study. The costs of Peg-G and Fil-G were calculated according to the National Health Insurance drug price list. We assessed an incremental cost-effectiveness ratio (ICER) for a single dose of Peg-G versus 11-days of Fil-G from the perspective of health insurance payers. The sensitivity and robustness of this model were validated by the tornado-diagram and Monte Carlo Method. The costs associated with primary prophylaxis with a single dose of Peg-G and 11-days of Fil-G were 109,628 JPY and 109,243 JPY, respectively. The quality adjusted life years (QALYs) associated with the two strategies were 0.0339 QALYs and 0.0337 QALYs, respectively.
