Survival rates among children with leukaemia in low-income countries are lower than those in high-income countries. This has been attributed in part to higher treatment-related mortality (TRM). We examined the demographics, treatment, and outcomes of paediatric patients in El Salvador with acute lymphoblastic leukaemia (ALL) or acute myeloid leukaemia (AML) to determine the incidence, causes, and risk factors for TRM. Two trained data managers collected data prospectively; no patients were excluded. Biological, socioeconomic and nutritional predictors were examined. A total of 469 patients with ALL and 78 patients with AML were included. The 2-year cumulative incidence of TRM was significantly higher among children with AML (35.4 ± 6.4%) than those with ALL (12.5±1.7%; Po0.0001). However, the proportion of deaths attributable to the toxicity of treatment did not differ significantly between AML (25/47, 53.2%) and ALL (55/107, 51.4%; P ¼ 0.98). Among children with ALL, low monthly income (P ¼ 0.04) and low parental education (P ¼ 0.02) significantly increased the risk of TRM. Among children with AML, biological, socioeconomic, and nutritional variables were not associated with TRM. In this low-income country, toxic death significantly contributes to mortality in both ALL and AML. A better understanding of the effect of socioeconomic status on TRM may suggest specific strategies for patients with ALL.

BackgroundInfection remains the most common cause of death from toxicity in children with cancer in low- and middle-income countries. Rapid administration of antibiotics when fever develops can prevent progression to sepsis and shock, and serves as an important indicator of the quality of care in children with acute lymphoblastic leukemia and acute myeloid leukemia. We analyzed factors associated with (1) Longer times from fever onset to hospital presentation/antibiotic treatment and (2) Sepsis and infection-related mortality.MethodThis prospective cohort study included children aged 0–16 years with newly diagnosed acute leukemia treated at Benjamin Bloom Hospital, San Salvador. We interviewed parents/caregivers within one month of diagnosis and at the onset of each new febrile episode. Times from initial fever to first antibiotic administration and occurrence of sepsis and infection-related mortality were documented.FindingsOf 251 children enrolled, 215 had acute lymphoblastic leukemia (85.7%). Among 269 outpatient febrile episodes, median times from fever to deciding to seek medical care was 10.0 hours (interquartile range [IQR] 5.0–20.0), and from decision to seek care to first hospital visit was 1.8 hours (IQR 1.0–3.0). Forty-seven (17.5%) patients developed sepsis and 7 (2.6%) died of infection. Maternal illiteracy was associated with longer time from fever to decision to seek care (P = 0.029) and sepsis (odds ratio [OR] 3.06, 95% confidence interval [CI] 1.09–8.63; P = 0.034). More infectious deaths occurred in those with longer travel time to hospital (OR 1.36, 95% CI 1.03–1.81; P = 0.031) and in families with an annual household income

Background Delivery of effective treatment for pediatric solid tumors poses a particular challenge to centers in middle-income countries (MIC) already vigorously addressing pediatric cancer. This study aimed to improve our understanding of barriers to effective treatment of pediatric solid tumors in MICs. Methods An ecological model centering in pediatric sarcoma and expanding to country as the environment were used as benchmark for studying delivery of solid tumor care in MICs. Data on resources was gathered from seven centers members of the Central American Association of Pediatric Hematologists and Oncologists (AHOPCA) using an infrastructure assessment tool. Pediatric sarcoma outcomes data was available and retrieved from hospital-based cancer registries for six of the seven centers and analyzed by country. Patients diagnosed from 1/1/2000-12/31/2009 with osteosarcoma, Ewing sarcoma, rhabdomyosarcoma, and other soft tissue sarcomas were included in the analysis. In order to explore correlations between resources and outcomes a pilot performance-index was created. Findings Results identified specific human resources, communication, quality and infrastructure deficits. Treatment abandonment rate, metastatic disease at diagnosis, relapse rate and 4-year abandonment-sensitive overall survival (AOS) varied considerably by country (1-38%, 15-54%, 24-52%, 21-51%, respectively). Treatment abandonment rate correlated inversely with health economic expenditure per capita (r= −0.86, p=0.03) and life expectancy at birth (r = −0.93, p=0.007). Four-year AOS correlated inversely with under-5 mortality rate (r= −0.80, p=0.05) and directly with the pilot performance-index (r =0.98, p=0.005). Interpretation Initiatives to improve treatment effectiveness of pediatric solid tumor care in MIC and pediatric sarcoma in particular are warranted. Building capacity and infrastructure, improving supportive care and communication, and fostering comprehensive multidisciplinary teams are identified as keystones in Central America. A measure that meaningfully describes performance in delivering pediatric cancer care is feasible and needed to advance comparative prospective analysis of pediatric cancer care and define resource-clusters internationally.

This survey study of physicians in Latin America who care for children with cancer investigates their perceptions about and comfort with pediatric palliative care and how their perceptions align with World Health Organization guidance.
