“…However, the unusual positioning of childhood histiotypes when compared with average global rankings [2,3] might be attributable to the suboptimal diagnostic and registration facilities of (childhood) cancer in Suriname [18]. This might have led to underdiagnosis of more frequently reported histiotypes such as central nervous system tumors, neuroblastoma, retinoblastoma, and renal tumors [2,3], which were hardly recorded in the current study.…”

“…This apparent inconsistency may be attributable to the incomplete cancer registry in Suriname (as mentioned before, around 85%). In analogy to a previous study [18], this may have led to incorrect estimations of the proportion of childhood cancers with respect to overall malignancies in the country. In addition, the higher upper age limit applied in the current study (19 years of age) when compared to that applied in various international studies (14 or 18 years of age; see for instance references 2 and 29) might have contributed to this discrepancy.…”

“…However, a baseline survey on the sex and age distribution of childhood cancer in Aden (Yemen) suggested that such results might be attributable to underdiagnosis and underregistration of a considerable number of cases [18]. As well, overall survival of children with acute lymphoblastic leukemia in Pakistan was worse than that reported in the literature (only 65%), which was probably attributable to the lack of proper supportive care causing high rates of infections and relapses [19].…”

Childhood cancer incidence in Suriname (South-America) was estimated using secondary data from 1980 to 2008, and these findings were stratified according to gender; age groups < 1, 1-4, 5-14, and 15-19 years; and the largest ethnic groups (Hindustanis, Maroons, Creoles, and Javanese). Data were expressed as total numbers, proportions, average yearly numbers, and/or crude incidence rates per 1,000,000 population per year. There were 290 malignancies in the period covered, i.e., about 10 new cases per year or 24 per 1,000,000 per year. The average yearly number of overall cancer increased from approximately 1 every two years in newborns to 3-4 per year in adolescents and young adults. Thirty to 35% of patients were Hindustani or Creole; the proportions of Javanese and Maroons patients were about twice and five times, respectively, lower. Leukemias and lymphomas comprised almost half of cases, each occurring 2 to 3 times per year. Bone tumors, soft-tissue sarcomas, and carcinomas were the most common non-hematological malignancies, occurring once or twice per year. Central nervous system tumors, neuroblastoma, retinoblastoma, renal tumors, primary hepatic tumors, and germ cell tumors were exceedingly rare. In conclusion, childhood cancer incidence in Suriname was relatively low; the individual histiotypes displayed an unusual ranking; and there were differences in the sex, age, and ethnic distribution of overall cancer as well as certain histiotypes. However, these observations might be biased by the use of crude rates, and underdiagnosis and incomplete registration of cases due to the absence of specialized (pediatric) cancer facilities in the country.

“…In registries in LMIC, real-time health surveillance tools are used for rapid quality improvement cycles [ 31 ]. LMIC registries contribute to independent prospective monitoring of trials and interventions [ 34 – 36 ], and large data collections are exploited to study rare conditions [ 35 , 37 , 38 ] and drug exposure [ 35 , 36 ], or conversely, register rare conditions only [ 37 , 39 , 40 ]. Registries in LMIC follow mothers to study recurrence of pregnancy outcomes [ 41 , 42 ], link mothers with offspring [ 29 , 43 – 45 ] with their subsequent newborn health records [ 46 ], and link children with siblings [ 47 – 49 ]; in some cases registries study long-term and family-based health determinants and recurrence [ 41 , 42 ] or undertaking twin studies [ 48 , 49 ].…”

BackgroundThe Global Roadmap for Health Measurement and Accountability sees integrated systems for health information as key to obtaining seamless, sustainable, and secure information exchanges at all levels of health systems. The Global Strategy for Women’s, Children’s and Adolescent’s Health aims to achieve a continuum of quality of care with effective coverage of interventions. The WHO and World Bank recommend that countries focus on intervention coverage to monitor programs and progress for universal health coverage. Electronic health registries - eRegistries - represent integrated systems that secure a triple return on investments: First, effective single data collection for health workers to seamlessly follow individuals along the continuum of care and across disconnected cadres of care providers. Second, real-time public health surveillance and monitoring of intervention coverage, and third, feedback of information to individuals, care providers and the public for transparent accountability. This series on eRegistries presents frameworks and tools to facilitate the development and secure operation of eRegistries for maternal and child health.MethodsIn this first paper of the eRegistries Series we have used WHO frameworks and taxonomy to map how eRegistries can support commonly used electronic and mobile applications to alleviate health systems constraints in maternal and child health. A web-based survey of public health officials in 64 low- and middle-income countries, and a systematic search of literature from 2005–2015, aimed to assess country capacities by the current status, quality and use of data in reproductive health registries.ResultseRegistries can offer support for the 12 most commonly used electronic and mobile applications for health. Countries are implementing health registries in various forms, the majority in transition from paper-based data collection to electronic systems, but very few have eRegistries that can act as an integrating backbone for health information. More mature country capacity reflected by published health registry based research is emerging in settings reaching regional or national scale, increasingly with electronic solutions. 66 scientific publications were identified based on 32 registry systems in 23 countries over a period of 10 years; this reflects a challenging experience and capacity gap for delivering sustainable high quality registries.ConclusionsRegistries are being developed and used in many high burden countries, but their potential benefits are far from realized as few countries have fully transitioned from paper-based health information to integrated electronic backbone systems. Free tools and frameworks exist to facilitate progress in health information for women and children.Electronic supplementary materialThe online version of this article (doi:10.1186/s12884-016-0801-7) contains supplementary material, which is available to authorized users.

“…11 We found that most retinoblastomas occurred in children younger than 5 years, which is similar to findings reported in other studies. 11,42,43 Although retinoblastoma is highly curable if diagnosed early, most children with retinoblastoma who are referred to the NCI are at an advanced stage. 44 Malignant bone tumours comprise approximately 5% of childhood neoplasms.…”

Background: Epidemiological studies of paediatric cancer incidence in Sudan are rare.Objectives: The aim of this study was to provide baseline information about the epidemiology of childhood cancers in patients treated at the National Cancer Institute (NCI) in Wad Medani, Sudan.Methods: We performed a retrospective health facility–based study of cancer incidence and patient characteristics of children who were treated at the NCI from January 1999 to December 2015. The changing patterns of cancers incidence during the study period were also recorded.Results: Of 15 387 new patients with cancer who were registered at the NCI during the study period, 1159 (7.5%) were children (younger than 15 years). The mean age of the paediatric patients was 7 years, with standard deviation of 5. Most of the patients (36%) were 10 to 15 years old, 33% were 0 to 4 years old and 31% were 5 to 10 years old. Among the study population, 60% were males and 40% were females. Approximately 76% of children lived in rural areas in Sudan. Leukaemias (29%) and lymphomas (26%) comprised 55% of all paediatric cancers. Central nervous system (CNS) tumours constituted 6% of all paediatric tumours, whereas non-CNS embryonal tumours (i.e. nephroblastoma, neuroblastoma, hepatoblastoma and retinoblastoma) accounted for 20%. The average number of cases per year increased from 42 in 1999–2005 to 75 in 2006–2010 and 106 in 2011–2015.Conclusion: The number of patients seeking treatment for childhood cancers has increased every year in central Sudan. Leukaemias and lymphomas constitute more than half of these cancers. A population-based cancer registry is needed to determine the true incidence of childhood cancers in Sudan.
