RESUMEN

BACKGROUND: Chemotherapy-induced neutropenia is a common adverse effect in children with cancer. Due to the high relative risk of infections and infectious complications, standard care for children with cancer and febrile neutropenia consists of routine hospitalization and parenteral administration of broad-spectrum antibiotics. However, there are less serious causes of febrile neutropenia; in a subgroup of these children, lengthy in-hospital treatment might be unnecessary. Various research groups have studied the adjustment of standard care to shorten in-hospital treatment for children with cancer and febrile neutropenia at low risk for bacterial infections. However, most of these studies were not done in a randomized matter. OBJECTIVES: To evaluate whether early discharge (mean/median of less than five days) from in-hospital treatment was not inferior to non-early discharge (mean/median of five days or more) and whether very early discharge (mean/median of less than 24 hours) was not inferior to early discharge, non-early discharge, or a combination of these, in children with cancer and febrile neutropenia. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (2015, issue 11), MEDLINE/PubMed (from 1945 to December 2015), EMBASE/Ovid (from 1980 to December 2015), the reference lists of relevant articles and review articles, and various conference proceedings (dependent on availability from 2005 to 2010 to 2013 to 2015). We scanned the International Standard Randomised Controlled Trials Number (ISRCTN) Register, the National Institute of Health Register for ongoing trials, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) on 9 January 2016. SELECTION CRITERIA: We included all randomized controlled trials and controlled clinical trials in which children with cancer and febrile neutropenia were divided in groups with different times of discharge. DATA COLLECTION AND ANALYSIS: We used standard methods of Cochrane and its Childhood Cancer Group. Two independent review authors performed study selection, data extraction, and risk of bias assessment. We entered data extracted from the included studies into Review Manager 5 and undertook analyses according to the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS: We included two randomized controlled trials assessing very early, early, non-early (or a combination of these) discharge in children with cancer and febrile neutropenia. We graded the evidence as low quality; we downgraded for risk of bias and imprecision. One study, Santolaya 2004, consisted of 149 randomized low-risk episodes and compared early discharge (mean/median of less than five days) to non-early discharge (mean/median of five days or more). This study found no clear evidence of difference in treatment failure (risk ratio (RR) 0.91, 95% confidence interval (CI) 0.24 to 3.50, P value = 0.89 for rehospitalization or adjustment of antimicrobial treatment, or both; Fischer's exact P value = 0.477 for death) or duration of treatment (mean difference -0.3 days, 95% CI -1.22 to 0.62, P value = 0.52 for any antimicrobial treatment; mean difference -0.5 days, 95% CI -1.36 to 0.36, P value = 0.25 for intravenous antimicrobial treatment; mean difference 0.2 days, 95% CI -0.51 to 0.91, P value = 0.58 for oral antimicrobial treatment). Costs were lower in the early discharge group (mean difference USD -265, 95% CI USD -403.14 to USD -126.86, P value = 0.0002). The second included study, Brack 2012, consisted of 62 randomized low-risk episodes and compared very early discharge (mean/median of less than 24 hours) to early discharge (mean/median of less than five days). This study also found no clear evidence of difference in treatment failure (RR 0.54, 95% CI 0.15 to 1.89, P value = 0.34 for rehospitalization or adjustment of antimicrobial treatment (or both); Fischer's exact P value = 0.557 for death). Regarding duration of treatment, median duration of intravenous antimicrobial treatment was shorter in the very early discharge group (Wilcoxon's P value ≤ 0.001, stated in the study) and median duration of oral antimicrobial treatment was shorter in the early discharge group (Wilcoxon's P ≤ 0.001, stated in the study) as compared to one another. However, there was no clear evidence of difference in median duration of any antimicrobial treatment (Wilcoxon's P value = 0.34, stated in the study). Costs were not assessed in this study. Neither of the included studies assessed quality of life. Meta-analysis was not possible as the included studies assessed different discharge moments and used different risk stratification models. AUTHORS' CONCLUSIONS: Very limited data were available regarding the safety of early discharge compared to non-early discharge from in-hospital treatment in children with cancer and febrile neutropenia and a low risk for invasive infection. The absence of clear evidence of differences in both studies could be due to lack of power.Evidently, there are still profound gaps regarding very early and early discharge in children with cancer and febrile neutropenia. Future studies that assess this subject should have a large sample size and aim to establish uniform and objective criteria regarding the identification of a low-risk febrile neutropenic episode.

RESUMEN

We report an increased incidence of infectious deaths during maintenance treatment of the ninth protocol for acute lymphoblastic leukaemia of the Dutch Childhood Oncology Group (DCOG-ALL-9). The main difference in maintenance treatment between DCOG-ALL-9 and the DCOG-ALL-7 and DCOG-ALL-8 protocols is the interruption of methotrexate and 6-mercaptopurine by vincristine (2mg/m(2) weekly) and dexamethasone (6mg/m(2) daily) for 14 days every 7 weeks in the DCOG-ALL-9 protocol. The 1107 children treated with the DCOG-ALL-7, DCOG-ALL-8 or DCOG-ALL-9 protocol were included and screened for infectious death during maintenance treatment (July 1988-July 2002). Seven of the 510 children died of severe infections during the maintenance phase of DCOG-ALL-9, compared to none of the 597 patients during the DCOG-ALL-7 and DCOG-ALL-8 protocols (1.37% versus 0.0%; p=0.013). Results from the current study suggest that repeated, prolonged exposure to dexamethasone results in an increase of lethal infections from 0% to 1.37%. In the dosing-schedule used, the advantage of dexamethasone may not outweigh the higher risk of infectious death.

RESUMEN

Children with cancer treated with chemotherapy are susceptible to bacterial infections and serious infectious complications. However, fever and neutropenia can also result from other causes, for which no antibiotic treatment is needed. In the past decades attempts have been made to stratify the heterogeneous group of pediatric cancer patients with fever and neutropenia into high- and low-risk groups for bacterial infections or infectious complications. Strategies for risk assessment have resulted in treatment regimens with early discharge or even no hospital admission at all, and/or treatment with oral or no antibiotics. We will provide a historical overview of the changing approach to low-risk fever and neutropenia, and we will also try to identify clear and objective parameters for risk assessment strategies and illustrate their relationship to innate immunity. In the future, new insights into genetic susceptibility on neutropenic fever might be of use in children with cancer with fever and neutropenia.

RESUMEN

Chemotherapy-induced neutropenia is a major dose-limiting side effect of intensive chemotherapy in cancer patients. Recently, pegfilgrastim (a product with a long half-life, resulting in once-per-cycle dosage) was introduced to prevent neutropenia in adults. The authors report 32 episodes of pegfilgrastim use in seven pediatric cancer patients to diminish chemotherapy-induced neutropenia. Feasibility was assessed by adherence to treatment protocol and safety was assessed by adverse effects. There were only two treatment delays (6%) due to neutropenia. No short-term adverse effects were recorded. The use of pegfilgrastim is feasible in pediatric cancer patients, without short-term adverse effects or major treatment delay due to neutropenia.
