AIM: We retrospectively analyzed 141 acute leukemia patients with unclassified invasive fungal disease episodes during chemotherapy to determine the optimum duration of antifungal treatment. PATIENTS & METHODS: Patients were divided into standard-risk and high-risk groups and treated with intravenous caspofungin for either 1 or 2 weeks, followed by oral voriconazole. RESULTS: Favorable responses occurred in 75.9% of patients (107/141) overall. Although there were no significant differences in response rates between patients receiving 1 or 2 weeks in the standard-risk group (p = 0.12 and p = 0.19, respectively), in the high-risk group, response rates were significantly higher in the 2-week than the 1-week treatment group (p = 0.01 and p = 0.02, respectively). CONCLUSION: The duration of caspofungin treatment for patients with unclassified invasive fungal diseases may be optimized by risk stratification.
