[Criteria of low risk of mortality in children with neutropenia and fever during cancer chemotherapy].

To validate the use of a lower-risk mortality profile in pediatric febrile neutropenia during anticancer therapy and to evaluate the efficacy of a sequential parenteral-oral antibiotic treatment for these children, a prospective study was conducted between May 1997 and December 1999. During this period 247 episodes in 215 patients were included in the present study. Children with neutropenia (ANC < 500/mm3) and fever (> 38 degrees C) due to anticancer therapy were eligible for the study if they presented the following lower-risk conditions: absence of severe co-morbidity factors, good clinical condition, no risk clinical foci, no bacteremia, and responsible parents. They were initially treated with inpatient parenteral short course of ceftriaxone and amikacin followed by ambulatory oral cefixime or ciprofloxacin to complete 7 days. Mean age was 64 (range: 8-200) months. The most common underlying malignant disease was acute lymphoblastic leukemia in 48% (118) of cases and 57% (141) of patients had an indwelling central venous catheter. Clinical evidence of infection was found in 47% (122) of children and the most common site was the upper respiratory tract (81%). Mean period of fever was 1.1 days (r: 1-8) and the duration of neutropenia was 3.9 days (r: 1-9). Sixty-one% (150) of children was discharged with neutropenia. Mean time of hospitalization was 1.5 days. Four clinical failures were detected (1.6%). They all were satisfactorily treated with a secondary treatment and none underwent any major complications or died. The lower-risk profile used was safe and the sequential antibiotic therapy was adequate to manage febrile neutropenia in this subset of children.
