Study of Empirical Antifungal Therapy in Febrile Neutropenia and Invasive Fungal Infection after Introduction of Novel Antifungal Agents / 대한의진균학회지

ABSTRACT

BACKGROUND: Patients with prolonged empirical broad spectrum antibiotics for febrile neutropenia (FN) with cancer, inevitably have increased risk of invasive fungal infections owing to the altered endogenous microbial environment. OBJECTIVE: The purpose of this study is to evaluate the impact of empirical antifungal therapy on occurrence of invasive fungal infections (IFIs) during FN with cancer. METHODS: We retrospectively reviewed medical records of patients with FN after cytotoxic chemotherapy due to cancer from July, 2003 to June, 2007. RESULTS: We identified 91 patients with FN after cytotoxic chemotherapy. Most common underlying conditions were lymphoma (20/91, 22%) and leukemia (20/91, 22%). IFIs occurred in 10% (9/91). In a comparison of patients with empirical antifungal therapy with no antifungal therapy, the duration of neutropenia was significantly increased with IFIs (p=0.09). The mortality of IFIs was 55.5% (5/9). CONCLUSION: We found that the duration of FN than empirical antifungal therapy affected occurrence of IFIs.
