Pediatric Solid Tumor Care and Multidisciplinary Tumor Boards in Low- and Middle-Income Countries in Southeast Asia

The development and education of a workforce in childhood cancer services in low- and middle-income countries: a scoping review protocol

BACKGROUND

An estimated 400,000 children develop cancer worldwide. Of those, 90% occur in low- and middle-income countries, where survival rates can be as low as 30%. To reduce the childhood cancer survival gap between high- and low- and middle-income countries (LMIC), the World Health Organization launched the Global Initiative for Childhood Cancer in 2018, to support governments in building sustainable childhood cancer programs, with the aim to increase access and quality of care for children with cancer. Developing a high-quality and trained workforce is key to the success of childhood cancer services, but more information is needed on the interventions used to develop and train a workforce. The objective of this review is to understand the key factors described in the literature in relation to the development and training of a workforce in childhood cancer (defined here as ages 0-19) in LMIC, including challenges, interventions and their outcomes.

METHODS

We will include sources of evidence that describe the development or training of a childhood cancer workforce in health services that diagnose, refer or treat children and adolescents with cancer, in low- and middle-income countries as defined by the World Bank. The following databases will be searched: OVID Medline, Embase and Pubmed from 2001 to present with no restriction of language. Grey literature searches will also be performed in Proquest Dissertation and Theses, as well as relevant organizations' websites, and conference proceedings will be searched in conference websites. In addition, references lists will be reviewed manually. Two people will screen abstracts and full-texts and extract data. Data will be presented in a table or chart, with an accompanying narrative summary responding to the review questions. A framework synthesis will be conducted: data will be charted against a framework adapted from the 2016 WHO Global Strategy for Human Resources for Heath: Workforce 2030.

DISCUSSION

This scoping review will allow to map the existing literature on workforce development in LMIC, identify potential interventions and highlight data and knowledge gaps. This constitutes a first step towards adopting successful strategies more broadly, formulating research priorities and developing effective policies and interventions.

Global Neuroblastoma Network: An international multidisciplinary neuroblastoma tumor board for resource-limited countries

BACKGROUND

Tumor boards are part of standard care of patients with complex cancers, but appropriate multidisciplinary expertise and infrastructure are often not available in low- and middle-income countries (LMIC) for pediatric cancers, such as neuroblastoma. Our goal was to review results of a Global Neuroblastoma Network (GNN) tumor board accessible to LMIC.

METHODS

De-identified clinical cases presented via internet conference during a weekly GNN virtual tumor board from 2010 through 2020 were evaluated in a standardized format, including diagnostic imaging, pathology, therapy information, resource limitations, and questions for discussion. Information summarized included the presentations, a survey of the impact on care, and a resource questionnaire.

RESULTS

Registered GNN participants included 575 individuals from 77 countries, with a median of 39 participants per session. Total 412 cases were presented from 32 countries, including 351 unique neuroblastoma patients, 52 follow-up cases, and nine non-neuroblastoma diagnoses. Twenty-eight educational sessions were presented. Limited critical resources for diagnostics and staging of cases included MYCN analysis (54.7%), metaiodobenzylguanidine (MIBG) scans (38.7%), and International Neuroblastoma Pathology Classification (49%). Therapies were also limited, with markedly decreased use of radiation and autologous stem cell transplant for high-risk cases, and no availability of anti-GD2 antibody in LMIC. Limited sampling with a post-presentation survey showed that 100% found the GNN helpful, and 70% altered the care plan based on the discussion.

CONCLUSION

This report shows the utility of an international tumor board for LMIC focused on a challenging solid tumor where local expertise may be limited, with international multidisciplinary expert participation and educational sessions.

Impact of treatment refusal and abandonment on survival outcomes in pediatric osteosarcoma in Southeast Asia: A multicenter study

BACKGROUND

Treatment refusal and abandonment (TxRA) are major barriers to improving outcomes among children with sarcomas of the extremities as curative treatment options bearing on amputation or disfiguring surgery, particularly in countries with limited resources. A multi-institutional retrospective study was conducted to determine the predictive factors for TxRA among patients with osteosarcoma associated with survival outcomes across Southeast Asia (SEA).

METHODS

Pediatric patients with osteosarcoma treated between January 1998 and December 2017 in four SEA pediatric oncology centers from three countries were studied. Nelson-Aalen estimates, Kaplan-Meier method, and Cox's proportion hazard model were applied to address the cumulative incidence, survival outcomes, and to identify prognostic factors associated with TxRA.

RESULTS

From a total of 208 patients with osteosarcoma enrolled; 18 (8.7%) patients refused and 41 (19.7%) patients abandoned treatment. Income classification of countries, age at diagnosis, tumor size, disease extent, chemotherapy protocols, and types of surgery were associated with TxRA. Tumor size more than 15 cm was an independent risk factor associated with TxRA. The 5-year overall and relapse-free survivals were 49.4% and 50.4%, respectively. However, these rates declined further to 37.9% and 35.8%, respectively, when TxRA were considered as events. Tumor size larger than 15 cm and metastatic disease were independent risk factors associated with TxRA-sensitive outcomes.

CONCLUSION

The prevalence of TxRA was high in SEA, particularly in lower middle-income countries. Factors associated with TxRA related to tumor burden. Treatment outcomes could be substantially improved by lowering the refusal and abandonment rates.

Building a Foundation for the Care of Children with Cancer in Rural North India

One of India's biggest challenges is to improve its global standing by increasing healthcare access and outcomes for children with cancer, with inferior overall survivorship compared with its Western counterparts. In conjunction with the government's efforts, private enterprise is crucial in delivering optimal cancer care consistently to its vast and diverse pediatric population, despite existing limitations. This article describes the successful implementation of a value-based, collaborative clinical and research framework by a philanthropic foundation in a rural Northern Indian city to establish and run a local childhood cancer service. It is proof of concept that substantial change could be brought about at grass roots level through resourceful partnerships and reduce prevailing imbalance in pediatric oncology service provision.

Mapping Pediatric Oncology Clinical Trial Collaborative Groups on the Global Stage

The global pediatric oncology clinical research landscape, particularly in Central and South America, Africa, and Asia, which bear the highest burden of global childhood cancer cases, is less characterized in the literature. Review of how existing pediatric cancer clinical trial groups internationally have been formed and how their research goals have been pursued is critical for building global collaborative research and data-sharing efforts, in line with the WHO Global Initiative for Childhood Cancer.

Local stakeholder engagement is necessary to collaborate with global pediatric cancer trial groups.

Gynecologic pathology services in low- and middle-income countries

OBJECTIVE

The International Gynecologic Cancer Society (IGCS) offers multidisciplinary conferences to underserved communities. Mentor pathologists have become an integral part of these tumor boards, as pathology services in low-to-middle-income countries are often inadequate and disjointed. The IGCS Pathology Working Group conducted a survey to assess barriers to quality pathology services in low-to-middle-income countries and identified potential solutions.

METHODS

A 69-question cross-sectional survey assessing different aspects of pathology services was sent to 15 IGCS Extension for Community Healthcare Outcomes (ECHO) training sites in Africa, Asia, Central America, and the Caribbean. Local gynecologic oncologists distributed the survey to their pathology departments for review. The responses were tabulated in Microsoft Excel.

RESULTS

Responses were received from nine training sites: five sites in Africa, two in Asia, one in Central America, and one in the Caribbean. There were no pathologists with subspecialty training in gynecologic pathology. Most (7/9, 78%) surveyed sites indicated that they have limited access to online education and knowledge transfer resources. Of the eight sites that responded to the questions, 50% had an electronic medical system and 75% had a cancer registry. Synoptic reporting was used in 75% of the sites and paper-based reporting was predominant (75%). Most (6/7, 86%) laboratories performed limited immunohistochemical stains on site. None of the sites had access to molecular testing.

CONCLUSIONS

Initial goals for collaboration with local pathologists to improve diagnostic pathology in low- and middle-income countries could be defining minimal gross, microscopic, and reporting pathology requirements, as well as wisely designed educational programs intended to mentor local leaders in pathology. Larger studies are warranted to confirm these observations.

Pediatric interventional radiology - does it add value?

Although attempts have been made to show that pediatric interventional radiology adds value in children's hospitals, none has been particularly persuasive. An analysis of individual procedures would seem to be the most scientific approach, but there are numerous problems, including the effects that different health care systems have on clinical practice and the difficulty of generalizing the results of a single-center study to other hospitals, even within the same type of health care system. It is unsurprising that there are no published randomized controlled trials comparing both the costs and outcomes of specific pediatric interventional radiology procedures with surgical alternatives, and in fact these may not be feasible. There is only anecdotal evidence of the value of pediatric interventional radiology in multidisciplinary teams in children's hospitals. Currently, the best justification may be the counterfactual: demonstrating what can go wrong if pediatric interventional radiology expertise is not available.
