Management of children with brain tumors in Paraguay

BACKGROUND Cure rates among children with brain tumors differ between low-income and high-income countries. To evaluate causes of these differences, we analyzed aspects of care provided to pediatric neuro-oncology patients in a low middle-income South American country. METHODS Three methods were used to evaluate treatment of children with brain tumors in Paraguay: (1) a quantitative needs assessment questionnaire for local treating physicians, (2) site visits to assess 3 tertiary care centers in Asunción and a satellite clinic in an underdeveloped area, and (3) interviews with health care workers from relevant disciplines to determine their perceptions of available resources. Treatment failure was defined as abandonment of therapy, relapse, or death. RESULTS All 3 tertiary care facilities have access to chemotherapy and pediatric oncologists but lack training and tools for neuropathology and optimal neurosurgery. The 2 public hospitals also lack access to appropriate radiological tests and timely radiotherapy. These results demonstrate disparities in Paraguay, with rates of treatment failure ranging from 37% to 83% among the 3 facilities. CONCLUSIONS National and center-specific deficiencies in resources to manage pediatric brain tumors contribute to poor outcomes in Paraguay and suggest that both national and center-specific interventions are warranted to improve care. Disparities in Paraguay reflect different levels of governmental and philanthropic support, program development, and socio-economic status of patients and families, which must be considered when developing targeted strategies to improve management. Effective targeted interventions can serve as a model to develop pediatric brain tumor programs in other low- and middle-income countries.

The My Child Matters programme: effect of public–private partnerships on paediatric cancer care in low-income and middle-income countries

In low-income and middle-income countries, an excess in treatment failure for children with cancer usually results from misdiagnosis, inadequate access to treatment, death from toxicity, treatment abandonment, and relapse. The My Child Matters programme of the Sanofi Espoir Foundation has funded 55 paediatric cancer projects in low-income and middle-income countries over 10 years. We assessed the impact of the projects in these regions by using baseline assessments that were done in 2006. Based on these data, estimated 5-year survival in 2016 increased by a median of 5·1%, ranging from -1·5% in Venezuela to 17·5% in Ukraine. Of the 26 861 children per year who develop cancer in the ten index countries with My Child Matters projects that were evaluated in 2006, an estimated additional 1343 children can now expect an increase in survival outcome. For example, in Paraguay, a network of paediatric oncology satellite clinics was established and scaled up to a national level and has managed 884 patients since initiation in 2006. Additionally, the African Retinoblastoma Network was scaled up from a demonstration project in Mali to a network of retinoblastoma referral centres in five sub-Saharan African countries, and the African School of Paediatric Oncology has trained 42 physicians and 100 nurses from 16 countries. The My Child Matters programme has catalysed improvements in cancer care and has complemented the efforts of government, civil society, and the private sector to sustain and scale improvements in health care to a national level. Key elements of successful interventions include strong and sustained local leadership, community engagement, international engagement, and capacity building and support from government.
