Abstract
Background
Empiric antifungal therapy is considered the standard-of-care for high-risk neutropenic patients with persistent fever. The impact of a pre-emptive, diagnostic-driven approach based on galactomannan (GM) screening and chest CT-scan on demand on survival and on the risk of invasive fungal disease (IFD) during the first weeks of high-risk neutropenia is unknown.
Methods
Patients with acute myeloid leukemia (AML), myelodysplastic syndrome (MDS) and allogeneic hematopoietic cell transplant recipients were randomly assigned to receive caspofungin empirically (Arm A) or pre-emptively (Arm B). All patients received fluconazole 400 mg daily as prophylaxis. The primary endpoint of this non-inferiority study was overall survival (OS) 42 days after randomization.
Results
Of 556 patients recruited, 549 were eligible: 275 in Arm A, 274 in Arm B. Eighty percent of the patients had AML or MDS requiring high-dose chemothe rapy and 93% of them were in first induction phase. At day 42, the OS was not inferior in Arm B (96.7%; 95% confidence interval (CI), 93.8 - 98.3%) when compared to Arm A (93.1%; 95% CI, 89.3 - 95.5%). The rates of IFDs at day 84 were not significantly different, 7.7% (95%CI, 4.5–10.8%) in Arm B versus 6.6% (95%CI, 3.6–9.5%) in Arm A, respectively. The rate of patients receiving caspofungin was significantly lower in Arm B (27%) than in Arm A (63%) (p < 0.001).
Conclusions
The pre-emptive antifungal strategy was safe for high-risk neutropenic patients given fluconazole as prophylaxis, halving the number of patients receiving antifungals without excess mortality or IFDs.
