- W2946987184 abstract "e18349 Background: Guidelines recommend primary prophylaxis(PP) use for patients receiving chemotherapy regimens with a high risk of febrile neutropenia (FN), which is 20% or higher. This study aim to evaluate the cost effectiveness of PP with pegfilgrastim (Brand name:Jinyouli), PP with filgrastim or no prophylaxis in women with early-stage breast cancer(BC) in China. Methods: A two-phase Markov model was developed for a hypothetical cohort of patients age 45 with stage II BC. First phase modeled costs/outcomes of 4 cycles docetaxel combined cyclophosphamide(TC×4) chemotherapy, with assumptions based on literature reviews including FN rates(Base-case (DSA range),0.29(0.24–0.35)) and related events (FN case-fatality, 3.4 (2.7–4.1)). Second phase models the long term survival which was suggested to link with the relative dose intensity (RDI)( Mortality HR for RDI < 85% vs. ≥85%,1.45 (1.00–2.32)). Clinical effectiveness, costs, and utilities were estimated from peer-reviewed publications and expert opinions in case of unavailability of published evidences. Results: Compared to PP filgrastim and no prophylaxis, PP pegfilgrastim was associated with higher costs 5208.19RMB and 5222.73RMB respectively, and increased quality-adjusted life-year (QALY) gained 0.066 and 0.297 respectively. Accordingly, the incremental cost effectiveness ratios (ICERs) are 79146.3RMB and 17558.77 RMB per QALY, which are both below the three times GDP per capita as the willingness to pay (WTP) threshold suggested by the WHO. Conclusions: Although the cost of PP pegfilgrastim is higher, considering the additional benefits, the administrating of PP pegfilgrastim is likely to be a cost-effective alternative to PP filgrastim and no prophylaxis in patients with early stage breast cancer in China." @default.
