title: [Fever profile of febrile neutropenia in patients treated with cancer chemotherapy for hematological malignancies].
abstract: It is important to diagnose infectious events in cancer patients during chemotherapy. Since many of them have complications of febrile neutropenia (FN), determining its cause is critical for their treatment course. We analyzed all febrile events (>38.0 degrees C, single axillary temperature) in hospitalized cancer patients treated at Shizuoka Cancer Center over a period of 8 months. Based on the clinical presentation at the onset, we estimated the cause of fever and classified it as infection, tumor fever, immunologic reaction or unknown. Clinical presentations found at the onset of FN were categorized into 4 groups: (1) oral mucositis, and (2) respiratory, (3) gastrointestinal and (4) cutaneous findings. We detected 85 febrile episodes (median age 58, range 26 approximately 86; 37 males and 48 females). Neutropenia was observed (500/mL) in 52. 9% (45/85) of the patients and clinical symptoms were detected in 74.1% (63/85). In eleven of 18 infection-proven cases, we successfully predicted the infection focus at the onset of fever. Multivariate analysis revealed that initial high fever, antimicrobial prophylaxis, cutaneous findings and severe neutropenia were important influencing factors in predicting infectious disease during FN. Physical examination can support the diagnosis of the cause of fever in FN patients.
