Efficacy and Cost-effectiveness of Pegfilgrastim for Preventing Febrile Neutropenia During Docetaxel, Cisplatin, and 5-Fluorouracil Therapy for Esophageal Cancer.

Abstract

The docetaxel, 5-fluorouracil, and cisplatin (DCF) regimen is an effective form of chemotherapy for advanced esophageal cancer. However, the incidence of adverse events, such as febrile neutropenia (FN), is high. This study retrospectively examined whether pegfilgrastim treatment reduces FN development during DCF therapy. This study evaluated 52 patients who were diagnosed with esophageal cancer and underwent DCF therapy at Jikei Daisan Hospital, Tokyo, Japan, between 2016 and 2020. They were divided into non-pegfilgrastim and pegfilgrastim-treated groups, and side-effects of chemotherapy and cost-effectiveness of pegfilgrastim were examined. Eighty-six cycles of DCF therapy were conducted (33 and 53 cycles, respectively). FN was observed in 20 (60.6%) and seven (13.2%) cases, respectively (p<0.001). The lowest absolute neutrophil count during chemotherapy was significantly lower in the non-pegfilgrastim group (p<0.001), and the number of days until improvement from nadir was significantly shorter in the pegfilgrastim group (9 vs. 11 days; p<0.001). No significant difference was found in the onset of grade 2 or more adverse events by Common Terminology Criteria for Adverse Events. However, renal dysfunction was significantly lower in the pegfilgrastim group (30.7% vs. 60.6%, p=0.038). Hospitalization costs were also significantly lower in this group (692,839 vs. 879,431 Japanese yen, p=0.028). This study revealed the usefulness and cost-effectiveness of pegfilgrastim in prevention of FN in patients treated with DCF.
