Randomized comparison of cefepime versus ceftazidime monotherapy for fever and neutropenia in children with solid tumors.
BACKGROUND
With the availability of new broad-spectrum antibiotics, initial therapy with a single agent has become an alternative to classic combinations, especially beta-lactam antibiotics plus aminoglycosides, in the management of febrile neutropenic cancer patients.


METHODS
Since January 1994, monotherapy has been used for empiric initial treatment at our center. The aim of this prospective randomized study is to compare the efficacy of cefepime (CFP), a new fourth-generation cephalosporin, and ceftazidime (CFZ) as empirical monotherapy of febrile neutropenic patients with solid tumors. From January 1998 to November 1998, 63 episodes of fever and neutropenia occurring in 33 children with solid tumors including lymphomas, were randomized to receive treatment with either CFP or CFZ. The patients were analyzed for leukocyte count and absolute neutrophil count (ANC) at entry, days in fever, neutropenia and hospitalization, and side effects of drugs. Success with or without modifications of the initial antibiotic was defined as survival through neutropenia; failure was death due to infection.


RESULTS
In our study group, with a median age of 7 [(1/12)-14] years, CFP was administered in 32, and CFZ in 31 episodes. An infection was documented microbiologically in eight episodes (25%) in the CFP arm and in nine episodes (29%) in the CFZ arm. The success rate with initial empiric monotherapy was 62.5% in the CFP arm and 61.3% in the CFZ arm respectively (P > 0.05). The total success rate (success with or without modification) was 100% in both arms. No major adverse effects were observed in either groups.


CONCLUSIONS
CFP is as effective and safe as CFZ for the empirical treatment of febrile episodes in neutropenic patients with solid tumors.
