Clinical and microbiological profile of febrile neutropenia in solid tumors and hematological malignancies at a tertiary cancer care center in South India

BACKGROUND: Febrile neutropenia (FN) is a common but serious complication of chemotherapy in patients with solid tumors (ST) and hematological malignancies (HM). The epidemiology of FN keeps changing. OBJECTIVE: The objective was to study the epidemiology of FN in adult patients with ST and HM at Kidwai Memorial Institute of Oncology, Bangalore - A tertiary cancer care center. MATERIALS AND METHODS: Data of all episodes of FN that occurred during the period July 2011 to December 2011 were collected prospectively and analyzed. RESULTS: A total of 75 episodes of FN was observed during study period involving 55 patients. Febrile neutropenic episodes were more frequent in HM than in ST (57% vs. 43%). The rate of bloodstream infection was 14.7%. Gram-negative organisms were the predominant isolates (56.25%). Overall mortality rate was 13.3%. Presence of medical co-morbidity and positive culture predicted high mortality. Mortality rate did not differ significantly between HM and ST (14% vs. 12.5%; P = 1.0). Gram-positive bacteremia was associated with greater mortality than Gram-negative bacteremia (P = 0.02). CONCLUSION: Empiric antibiotic treatment for FN should be tailored to the locally prevalent pathogens and their susceptibility patterns.
