Abstract | BACKGROUND: METHODS: We obtained data from 346 Japanese breast cancer patients in a randomized, placebo-controlled clinical trial comparing FN incidence due to TC adjuvant chemotherapy ( docetaxel 75 mg/m2, cyclophosphamide 600 mg/m2) between pegfilgrastim-treated and placebo groups. We estimated mean costs for chemotherapy drugs, drugs for all AEs and FN, and hospitalization for all AEs and FN. We also calculated mean costs associated with drugs and hospitalization for FN specifically for patients who developed FN in the placebo group. RESULTS: For the pegfilgrastim and placebo groups, the total cost during the first cycle of chemotherapy was ¥189 135 and ¥98 106. This difference is associated with prophylactic use of pegfilgrastim. Our analysis clarified in the placebo group that FN incidents of 119/173 (68.6%), the mean drug cost related to all AEs and hospitalization caused by the first cycle of chemotherapy were ¥14 411and ¥11 180, respectively. The cost of each for FN treatment was ¥16 429 for the placebo group. The mean treatment cost for patients who developed FN in placebo group, was ¥11 145 for drugs and ¥28 420 for drugs and hospitalization. CONCLUSIONS:
Pegfilgrastim reduced the costs incurred for both drugs and hospitalization for AEs as well as FN, although the total medical cost during the chemotherapy increased. Our study constitutes baseline data for further health economic evaluations of pegfilgrastim.
