Abstract
Objectives
We intended to determine the predictive factors of poor prognosis in cancer patients with chemotherapy-induced febrile neutropenia (FN).
Methods
From January 1, 2007 to December 31, 2008, 396 episodes of FN in 346 cancer patients were retrospectively analyzed. Clinical and laboratory findings and Multinational Association of Supportive Care in Cancer (MASCC) risk-index score were analyzed and correlated with outcome.
Results
Of the 396 episodes, 73 (18.4%) had serious medical complications including 15 (3.8%) deaths. There was significant difference between unfavorable and favorable outcomes in age, gender, hypotension, tachypnea, duration of fever ≤24 h before admission (44.4% vs. 61.3%), interval of ≤7 days since last chemotherapy (34.2% vs. 16.1%), and duration of neutropenia ≥4 days (34.2% vs. 15.8%; P < 0.05 each), as did C-reactive protein (CRP; 15.0 vs. 7.5 mg dL-1) and platelet count (66.4 × 103 vs. 123.7 × 103 mm-3;P < 0.001 each). MASCC score was significantly lower in unfavorable outcomes than favorable outcomes (19.0 vs. 24.6, P < 0.001). However, prophylactic antibiotics, treatment with granulocyte colony-stimulating factor (G-CSF), and history of FN were not associated with outcome. On multivariate analysis, MASCC risk-index score (OR 23.2, 95% CI 10.48–51.37), tachypnea (OR 3.61, 95% CI 1.44–9.08), thrombocytopenia (OR 3.41, 95% CI 1.69–6.89), increased CRP (OR 3.23, 95% CI 1.62–6.45), and prolonged neutropenia (OR 2.52, 95% CI 1.21–5.25) were independent predictors of unfavorable outcomes.
Conclusion
MASCC risk-index score <21, tachypnea, thrombocytopenia, increased CRP, and prolonged neutropenia may be strongly associated with poor outcomes in cancer patients with FN.
