It is possible to distinguish between pediatric oncology patients who are at high or low risk for serious infection during periods of fever and treatment related neutropenia based on clinical parameters. Patients with low risk can be safely treated as outpatients primarily using oral antibiotics. It is possible to improve methods of risk stratification through the addition of genomic and proteomic factors.
Outpatient management of patients considered to be at low risk for serious bacterial infection has been explored using risk stratification schema based on clinical parameters. First, patients will be stratified based on a clinical risk stratification schema. Patients stratified to the low risk group will be randomized between treatment using standard inpatient intravenous antibiotic therapy or outpatient antibiotic therapy using primarily an oral regimen. Second, an evaluation of proteins important to the innate immune system will be performed to provide a molecular characterization of episodes based on etiology. Third, single nucleotide polymorphisms in genes important for innate immunity will be evaluated to determine effect of each on infection risk during treatment induced neutropenia. Finally, we will develop a bank of both plasma and DNA specimens correlated with clinical outcomes for future use.

NONE
Intravenous Levaquin initially, then oral dosing. Patient discharged to go home to finish medication cycle after initial 120 minutes observation. Patients will be evaluated daily in the clinic, and his or her temperature must be taken and recorded four times per day. Blood cultures will be drawn at clinic visits.
Broad spectrum intravenous antibiotics. Daily blood work will be drawn, and patients will be monitored for fever and neutropenia in hospital.

Low Risk Treatment
The response to initial antibiotic management without modification with regards to resolution of the episode of fever and neutropenia, measured through blood cultures
Time frame: Start of study to end of study, up to two years
Protein Evaluation
Comparison of the level of each protein at the initiation of each episode versus resolution to determine if there is a pattern of proteins that correlates with an infectious outcome, measured using ELISA techniques
Time frame: Start of study to end of study, up to two years
Genomics Evaluation
A comparison of proven infections between patients with the wild-type and variant forms of each gene studied, taken through DNA specimens
Time frame: Start of study to end of study, up to two years
Cost Benefit Analysis
A cost-benefit analysis between the arms, duration of fever per episode between the arms, and number of admissions or deaths. Medical cost will be obtained through billing records and indirect costs will be estimated through information obtained from the family.
Time frame: Start of study to end of study, up to two years
Protein Evaluation
Determine trends of protein markers on days 3 and 5 of evaluation, using ELISA techniques.
Time frame: Start of study to end of study, up to two years
Genomics Evaluation
A comparison of the number of episodes of fever and neutropenia per patient and the duration of fever per episode between the wild type and variant forms of each gene, taken through DNA specimens.
Time frame: Start of study to end of study, up to two years
