Objective: Patients with neutropenia due to cancer chemotherapy are prone to severe infections. Cancer patients can experience %26gt;1 infectious episode during the same period of neutropenia. This study aimed to determine the etiological and clinical characteristics of secondary infectious episodes in cancer patients with febrile neutropenia and to identify the factors associated with the risk of secondary infectious episodes. %26lt;br%26gt;Material and Methods: All cancer patients that received antineoplastic chemotherapy at Ankara University, School of Medicine, Department of Hematology between May 2004 and May 2005 and developed neutropenia were included in the study. Data were collected using survey forms that were completed during routine infectious diseases consultation visits. Categorical data were analyzed using the chi-square test, whereas Student%26apos;s t-test was used for continuous variables. Multivariate logistic regression analysis was performed to identify independent predictors of secondary infections (SIs). %26lt;br%26gt;Results: SIs were observed during 138 (53%) of 259 febrile neutropenic episodes. Of the 138 episodes, 89 (64.5%) occurred in male patients with a mean age of 40.9 years (range: 17-76 years). In total, 80% of the SIs were clinically or microbiologically documented. Factors on d 4 of the initial febrile episode were analyzed via a logistic regression model. The presence of a central intravenous catheter (OR: 3.01; P %26lt; 0.001), acute myeloid leukemia (AML) as the underlying disease (OR: 2.12; P = 0.008), diarrhea (OR: 4.59; P = 0.005), and invasive aspergillosis (IA) during the initial febrile episode (OR: 3.96; P = 0.009) were statistically significant risk factors for SIs. %26lt;br%26gt;Conclusion: Among the cancer patients with neutropenia in the present study, AML as the underlying disease, the presence of a central venous catheter, diarrhea, and IA during the initial febrile episode were risk factors for the development of SIs.
