Abstract

Purpose: Anthracycline and ifosfamide-based chemotherapy represents a widely used regimen both in early and advanced settings in soft tissue sarcoma (STS). Prophylaxis with granulocyte colony-stimulating factor (G-CSF) reduces the severity of chemotherapy-induced neutropenia. The aim of this study was to assess the efficacy and safety of biosimilar G-CSF in these patients. Methods: Between 2003 and 2013, 67 patients with soft tissue tumors under epirubicin and ifosfamide (EI) treatment receiving biosimilar filgrastim (Zarzio®), originator filgrastim (Granulokine®, Neupogen®), and lenograstim (only originator Myelostim®) as primary prophylaxis for a total of 260 cycles of therapy were retrospectively analyzed. Baseline patient characteristics were summarized in a propensity score (PS). Results: The incidence of febrile neutropenia (FN) was 44.0 % in biosimilar filgrastim, 40.0 % in originator filgrastim, and 45.5 % in the lenograstim groups (p = 0.935). All grade and G4 neutropenia were similar in the three groups with the same safety profile. The use of biosimilar filgrastim achieved cost savings of €225.25 over originator filgrastim and €262.00 over lenograstim. Conclusion: Biosimilar G-CSF was effective in preventing FN and in reducing the need for hospitalization in STS patients undergoing EI treatment. It also proved comparable to its reference products from both a clinical and cost-effective standpoint.
