Hendricks M, Cois A, Geel J, van Heerden J, Dandara C, Mohamed K, Donald KA, Kruger M. Socioeconomic status significantly impacts childhood cancer survival in South Africa. Pediatr Blood Cancer 2023; 70:e30669. [PMID: 37705154 DOI: 10.1002/pbc.30669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Revised: 08/15/2023] [Accepted: 08/28/2023] [Indexed: 09/15/2023]
Abstract
BACKGROUND AND AIMS Significantly discrepant survival rates have been documented in single disease childhood cancer cohorts in South Africa; those from higher socioeconomic groups were shown to have a significantly lower risk of death than those from less affluent households. This study aimed to determine the impact of socioeconomic status (SES) on childhood cancer survival using pooled South African data. METHODS Five databases spanning January 2000 to December 2021 were interrogated. SES status was assigned based on a public sector annual household income classification. H0 households (formally unemployed) received free healthcare. H1, H2 and H3 (annual income > United States Dollar [USD] 19,000) households paid for healthcare relative to their income. The Spearman test assessed correlations between SES and disease stage in patients with solid tumours. Hazard ratios were determined using Cox regression modelling. The Kaplan-Meier procedure estimated overall survival (OS). RESULTS A total of 1598 children were eligible for analysis; 1269 had a solid tumour with a negative correlation between SES and stage (Spearman rho = -.178; p < .001). Patients with solid tumours and lower SES showed proportionately higher numbers of stage III and IV disease (p < .01). This proportion decreased with higher SES categories. In the multivariate analyses adjusted for sex, age, tumour type and stage, higher SES was associated with lower mortality risk (p < .001), indicating that the impact of SES on survival was in excess of any effect that could be explained by lower stage disease alone. There was a strong positive correlation between race and SES (Fisher's exact tests, p < .001) across all groups and all SES strata. Five-year OS was 85.3% in children from H3 households versus 46.3% in children from H0 households (p < .001). CONCLUSION SES significantly impacts childhood cancer survival for children with solid tumours in South Africa. SES is a robust surrogate for race in South Africa as a prognostic metric of disease outcome in childhood cancer. Advocacy to increase social support for impoverished patients is essential to achieve equitable improvements in outcomes treated with standardised national treatment guidelines.

Abstract
Neuroblastoma (NB) is the most common extracranial solid tumor of childhood. The complete burden and outcomes in Uganda are unknown. The study was a multicenter retrospective chart review of children aged between 0 to 15 years diagnosed with NB from 2010 to 2020. Demographic, clinical and tumor-related characteristics were extracted for analysis. Kaplan-Meier survival curves and Cox regression models were used to determine the one-year overall survival (OS) and identify prognostic factors. Seventy-five patients were evaluated, with a median age at diagnosis of 48 months (IQR 26-108 months). Fever (74.7%), weight loss (74.7%), high blood pressure (70.3%) and abdominal swelling/mass (65.3%) were the most common features at diagnosis. Suprarenal tumors (52%) and stage 4 disease (70.7%) were also common. The one-year OS was 60.0% (95%CI 56.8%; 64.3%) with a median survival time of 12.6 months (95% CI: 8.1; 20.8). The one-year OS for non-metastatic and metastatic disease was 67.3% and 42.6% (p = 0.11) respectively. Leukocytosis (p < 0.001) at diagnosis was of prognostic significance while clinical remission after induction chemotherapy (p < 0.001) provided survival advantages. Children who received maintenance chemotherapy had a longer median survival time of 38.5 months (range 10.8-69.5). Age (p = 0.001), lung metastasis (p < 0.001), and leukocytosis (p < 0.001) remained significant on multivariate analysis. In this Ugandan study, leukocytosis was a clinical predictor of prognosis, metastatic disease had management challenges and maintenance chemotherapy prolonged the survival time but not OS.

Abstract
Surgical control has prognostic value in neuroblastoma (NB). Advanced NB is common at diagnosis in South Africa. We investigated the pre-surgery factors that influenced decisions to perform surgical resections. We included 204 patients with high-risk NB from a national retrospective study, who completed induction chemotherapy between 2000 and 2016.The median age was 32.4 months (IQR 15.1 - 53.5 months). Primary tumor resection was achieved in 76.9% of patients between 0-18 months of age, 51.8% between 18-60 months and 51.7% older than 60 months (p < 0.001). Only 43.2% of patients with distant metastatic disease had surgery done (p < 0.001). LDH was >750 U/L in 46.8% and ferritin >120 g/dL in 53.1% of those who had surgery (p = 0.005). The majority (80.4%), who had achieved post-induction metastatic complete remission (mCR), were operated, while 28.7% without mCR had surgery (p < 0.001). The long-term overall survival in patients with mCR and primary tumor resection was 36.5% compared to those with mCR without primary tumor resection (25.4%) and without mCR (≤3.0%)(p < 0.001). Age (p < 0.001), stage (p < 0.001), mCR (p < 0.001) and treatment setting (p < 0.001) were of prognostic significance. The tumor site and MYCN-amplification did not significantly predict resection rates. Post-induction mCR and stage were associated with surgical resection and five-year OS (p < 0.001) on multivariate analysis.Patients with high-risk NB who achieved mCR and had primary tumor resections are curable in limited resourced settings. Stage and post-induction mCR were significant variables that led to surgery. These variables should be included as indications in the management of metastatic NB in resource limited settings.

Abstract
Abstract
Background
Cancer is a major global health concern and a leading cause of death in paediatric populations worldwide. Malnutrition contributes to a poor prognosis and remains the most common comorbidity leading to death in children with cancer. This retrospective study was developed through Oxford Paediatrics Linking Oncology Research with Electives (OxPLORE)—a medical student-led collaboration of paediatric surgeons and oncologists from low- and middle-income (LMIC) and high-income (HIC) countries. The aim of this study was twofold; firstly, to investigate the nutritional status and outcomes of neuroblastoma paediatric patients in two OxPLORE centres. Secondly, to facilitate the development of research skills of medical students as part of the OxPLORE initiative.
Results
Nine neuroblastoma patients were identified (YY, n = 4, XX, n = 5) over the study period. Nutritional status was poorer in YY patients (median z-score − 1.57 cf. − 0.7, t = 1.16, p = 0.28), which correlated with poorer survival in the YY cohort (75%), as compared to the XX cohort (100%). YY patients were older at presentation than the XX cohort (57 cf. 13 months, t = 1.959 p = 0.09). Further, tumour presentation was at a later stage in the YY group (75% stage IV).
Conclusion
This collaboration has shown a correlation in disparities in nutritional status and outcome of neuroblastoma in paediatric populations in YY and XX. These findings can inform institutional quality improvement. Further, this pilot study has highlighted the potential for medical students to undertake international research collaborations.

Abstract
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.

Abstract
AIMS Image-defined risk factors (IDRFs) in neuroblastoma predict surgical complications and management outcomes. As there is a lack of data regarding the association of IDRFs with clinical and pathological factors, this study evaluated the prognostic value of IDRFs to predict neuroblastoma survival outcomes. MATERIALS AND METHODS This was a retrospective study including 345 patients and reviewed diagnostic imaging for 20 IDRFs, pleural effusions and ascites. The IDRFs were grouped into five 'primary IDRFs' cohorts with vascular encasement, involvement of multiple body compartments, organ infiltration, airway obstruction and intraspinal extension. The association between clinical, histopathological and biological characteristics of neuroblastoma and management was evaluated. RESULTS More patients without IDRFs had operations compared with patients with IDRFs, with a trend towards significance (64.4% versus 35.6%, P = 0.082). Patients with multiple compartment tumour involvement (P = 0.003) and organ infiltration (P < 0.001) had a higher risk of surgical complications. The 5-year overall survival of the group with more than one IDRF was 0.0% and those with pleural effusions or ascites 6.7%, associated with the worst outcome (P = 0.005). The total number of IDRFs was not predictive of the metastatic remission rate (P = 0.585) or overall survival (P = 0.142), with no conclusive association found between IDRF groups and clinical or biological markers. CONCLUSIONS Patients with more than one IDRF had the shortest survival time, whereas those with pleural effusions and ascites at diagnosis had a poor outcome. Standardised reporting of IDRFs is crucial for predicting prognosis.

Abstract
In November 2018, theInternational Society of Paediatric Oncology (SIOP) launched a project to map African facilities providing pediatric oncology treatment. A 55-item digital survey was created in English, piloted in India, translated to French and Portuguese, and distributed by email, social media, or personal contacts. December 2019, 48/54 African countries responded (72% surveys completed and analyzed). Issues included incomplete responses, multiple entries for one facility with conflicting data for key services, and repeated entries with varied answers by the same respondent. The facility mapping project, now on-going program will serve as a global registry of global pediatric cancer centers.

Abstract
PURPOSE Adequate clinical services have yet to be established in the majority of African countries, where childhood cancer survival rates vary from 8.1% to 30.3%. The aim of this review is to describe the landscape of pediatric oncology trials in Africa, identify challenges, and offer future opportunities for research collaborations. METHODS The study includes data from the International Pediatric Oncology Society (SIOP) global mapping survey, meta-research identifying trials in Africa in ClinicalTrials.gov, and a literature overview of publications on the subject of pediatric oncology clinical research supported by expert opinions on the current situation and challenges. RESULTS The SIOP global mapping survey received responses from 47 of 54 African countries, of which 23 have active clinical research programs. A preliminary search of ClinicalTrials.gov showed that only 105 (12.1%) of 868 African oncology studies included children and adolescents. Of these, 53 (50.5%) were interventional trials according to the registry’s classification. The small number of African trials for children and adolescents included palliative care and leukemia trials. In African oncology journals and international pediatric oncology journals, < 1% of the pediatric oncology publications come from Africa. Services and research were strengthened by international collaboration. National studies focused on clinical needs, local challenges, or interventional priorities. Both the literature review and the expert opinions highlight the need to expand clinical research in Africa, despite ongoing regional instability and lack of resources. CONCLUSION While a low number of pediatric clinical treatment trials are open to African children and adolescents, clinical research of high quality is being done in Africa. Several initiatives are stimulating the development of the research capacity across the continent, which should increase the publication output.

Abstract
BACKGROUND Neuroblastoma (NB) contributes the most to the mortality of childhood malignancies worldwide. The disease spectrum is heterogenous and the management complex and costly, especially in advanced disease or disease with adverse biology. In low- and middle-income countries (LMICs) the majority of NB presents in advanced stages. Therefore, with limited resources and poor prognosis the treatment of NB is often not a priority. The aim of the study was to evaluate the research activities and perceptions of the management of NB that determine the research and treatment approaches in LMICs. METHODS Data were sourced from https://www.clinicaltrials.gov/ identifying NB trials open to LMIC. Abstracts on NB research presented at the International Society for Paediatric Oncology (SIOP) Congresses between 2014 and 2020 were evaluated according to income status. An online survey evaluating medical views on NB in LMICs and the effect on the management was conducted. Descriptive analysis was done. Where appropriate categorical association between covariates was assessed using the Pearson chi-square (χ2 ) test or Fishers exact test. RESULTS There were 15/562 (2.7%) trials open to LMIC. Only six of 138 (4.3%) LMIC participated in NB trials. Of the 688 abstracts presented between 2014 and 2020 at the SIOP International Congress on NB as primary subject, 297 (42.7%) were from LMICs. Only two were from low-income countries (LICs). Sixty-one countries responded to the NB survey. Positive views towards NB management were present when treatment was based on a national protocol, the availability of trimodal or advanced treatment options were present, and when a balance of metastatic or local disease were treated. CONCLUSION Management of NB in LMICs should include increased advocacy and research as well as implementation of national management strategies.

Abstract
The majority of patients with high-risk neuroblastoma (HR-NB) in low- and middle-income countries (LMIC) do not have access to autologous stem cell transplant (ASCT) and dinutuximab. Consolidation with nonmyeloablative chemotherapy is not well-defined, and the outcomes are variable. We report a single-center outcome of patients with HR-NB, treated with nonmyeloablative consolidation. A tabulated compilation of similar reports is included. A retrospective chart review of patients with HR-NB was performed from January 2009 till June 2016. Patients were treated on the backbone of HR-NBL1/SIOPEN protocol. Treatment included induction with rapid-COJEC, surgery, followed by consolidation. Consolidation involved 4 cycles of topotecan, vincristine, and doxorubicin (TVD) instead of ASCT. Infusion of vincristine and doxorubicin were modified for ease and to enable administration in the clinic. Subsequent treatment included radiotherapy to the primary tumor and differentiation therapy with isotretinoin. Over 7½ years, 28 patients with HR-NB were treated. Two (7%) patients had therapy-related mortality. A relapse or disease progression occurred in 11 (39%) patients at a median duration of 17 months (IQR: 5, 18). Treatment abandonment was observed in 4 (14%) patients. The median follow-up of disease-free patients was 49 months (IQR: 45, 79). Patients with relapse were not treated further. A 4-year EFS of 29.3% was observed when 4-cycles of TVD were administered instead of ASCT in patients with HR-NB. The study and the review will aid decision-making for care of patients in LMIC while considering the options of treatment for HR-NB if access to ACST and dinutuximab is lacking.

Abstract
Purpose The aim of the World Health Organization-International Paediatric Oncology Society is to improve childhood cancer survival in low- and middle-income countries to 60% by 2030. This can be achieved using standardised evidence-based national treatment protocols for common childhood cancers. The aim of the study was to describe the development and implementation of the SACCSG NB-2017 neuroblastoma (NB) treatment protocol as part of the treatment harmonisation process of the South African Children’s Cancer Study Group. Methods The Consolidated Framework for Implementation Research was used to identify factors that could influence the implementation of the national NB protocol as a health care intervention. The evaluation was done according to five interactive domains for implementation: intervention characteristics, inner setting, outer setting, individual or team characteristics and the implementation process. Results The protocol was developed over 26 months by 26 physicians involved in childhood cancer management. The process included an organisational phase, a resource identification phase, a development phase and a research ethics approval phase. Challenges included nationalised inertia, variable research ethical approval procedures with delays and uncoordinated clinical trial implementation. Conclusion The implementation of the national NB protocol demonstrated the complexity of the implementation of a national childhood cancer treatment protocol. However, standardised paediatric cancer treatment protocols based on local expertise and resources in limited settings are feasible.

The Association between Tumour Markers and Meta-iodobenzylguanidine Scans in South African Children with High-risk Neuroblastoma. Clin Oncol (R Coll Radiol) 2021; 33:517-526. [PMID: 33781675 DOI: 10.1016/j.clon.2021.03.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 02/04/2021] [Accepted: 03/04/2021] [Indexed: 12/13/2022]
Abstract
AIMS Diagnostic and post-induction 123I-meta-iodobenzylguanidine (123I-mIBG) scans have prognostic significance in the treatment of neuroblastoma, but data from low- and middle-income countries are limited due to resource constraints. The aim of this study was to determine the association between neuroblastoma-associated tumour markers (lactate dehydrogenase [LDH], ferritin and MYCN amplification) and 123I-mIBG scans (modified Curie scores and metastatic disease patterns) in predicting complete metastatic response rates (mCR) and overall survival. MATERIALS AND METHODS Two hundred and ninety patients diagnosed with high-risk neuroblastoma in South Africa between January 2000 and May 2018 and a subanalysis of 78 patients with diagnostic 123I-mIBG scans were included. Data collection included LDH, ferritin and MYCN amplification at diagnosis. Two nuclear physicians independently determined the modified Curie scores and pattern of distribution for each diagnostic and post-induction 123I-mIBG scans with high inter-rater agreement (r = 0.952) and reliability (K = 0.805). The cut-off values for the diagnostic and post-induction modified Curie scores of ≥7.0 (P = 0.026) and 3 (P = 0.009), respectively, were generated. The association between the tumour markers and the modified Curie score of the 123I-mIBG scans was determined using post-induction mCR and 2-year overall survival. RESULTS Diagnostic LDH (P < 0.001), ferritin (P < 0.001) and the diagnostic modified Curie scores (P = 0.019) significantly predicted mCR. Only ferritin correlated with diagnostic modified Curie scores (P = 0.003) but had a low correlation coefficient of 0.353. On multivariable analysis, the only significant covariate for 2-year overall survival at diagnosis was LDH <750 U/l (P = 0.024). A post-induction chemotherapy modified Curie score ≤3.0 had a 2-year overall survival of 46.2% compared with 30.8% for a score >3.0 (P = 0.484). CONCLUSION LDH, ferritin and the diagnostic 123I-mIBG scans significantly predicted mCR, but only LDH predicted 2-year overall survival. Ferritin and the modified Curie scores correlated with each other. MYCN amplification neither correlated with any aspect of the 123I-mIBG scans nor significantly predicted mCR or 2-year overall survival. LDH and ferritin are therefore appropriate neuroblastoma tumour markers to be used in low- and middle-income countries with limited or no access to mIBG scans and/or MYCN amplification studies.

Abstract
BACKGROUND The majority of patients in low- and middle-income countries (LMIC) are unable to receive optimal therapy, including autologous stem cell transplant (ASCT) for high-risk neuroblastoma. Management is intensive and multidisciplinary; survival is often poor. We report a single-center outcome of high-risk neuroblastoma, with adaptations optimized for LMIC. PROCEDURE The study was retrospective. Patients were treated on the backbone of the high-risk neuroblastoma study-1 of SIOP-Europe (HR-NBL1/SIOPEN) protocol with ASCT. Adaptations incorporated to decrease cost, requirement for inpatient admission, infections, and faster engraftment included (a) optional outpatient administration for rapid-COJEC, (b) two sessions of stem-cell apheresis, (c) storing stem cells at 2-6°C without cryopreservation for up to 7 days, (d) no central lines, (e) no antibacterial/antifungal/antiviral prophylaxis, (f) omitting formal assessment of cardiac/renal/pulmonary functions before ASCT, and (g) administration of pegylated granulocyte colony-stimulating factor on Day +4. RESULTS Over 5 years 9 months, 35 patients with high-risk neuroblastoma were treated. Rapid-COJEC was administered over a median duration of 80 days (interquartile range: 77, 83). Conditioning regimen included melphalan (n = 7), oral busulfan-melphalan (Bu/Mel; n = 6), or intravenous Bu/Mel (n = 22). The median viability of stem cells stored for 6 days (n = 28) was 93% (range: 88-99). Two (5.7%) patients had ASCT-related mortality. The 3-year overall and event-free survival was 41% and 39%, respectively. A relapse occurred in 20 (57%) patients. Treatment abandonment was observed in one (3%) patient. CONCLUSIONS Administration of therapy in a disciplined time frame along with low-cost adaptations enables to manage high-risk neuroblastoma with low abandonment and an encouraging survival in LMIC. Stem cells can be stored safely without cryopreservation for up to 7 days.

Abstract
Achieving remission after induction therapy in high-risk neuroblastoma (HR-NB) is of significant prognostic importance. This study investigated remission after induction-chemotherapy using three standard neuroblastoma protocols in the South African (SA) setting. Retrospective data of 261 patients with HR-NB diagnosed between January 2000 and December 2016, who completed induction chemotherapy with standard treatment protocols were evaluated. The treatment protocols were either OPEC/OJEC or the St Jude NB84 protocol (NB84) or rapid COJEC (rCOJEC). The postinduction metastatic complete remission (mCR) rate, 2-year overall survival (OS) and 2-year event free survival (EFS) were determined as comparative denominators. The majority (48.3%; n = 126) received OPEC/OJEC, while 70 patients received (26.8%) rCOJEC and 65 (24.9%) NB84. Treatment with NB84 had the best mCR rate (36.9%), followed by OPEC/OJEC (32.5%) and rCOJEC (21.4%). The 2-year OS of treatment with NB84 was 41% compared to OPEC/OJEC (35%) and rCOJEC (24%) (p = 0.010). The 2-year EFS of treatment with NB84 was 37% compared to OPEC/OJEC (35%) and rCOJEC (18%) (p = 0.008). OPEC/OJEC had the least treatment-related deaths (1.6%) compared to rCOJEC (7.1%) and NB84 (7.5%) (p = 0.037). On multivariate analysis LDH (p = 0.023), ferritin (p = 0.002) and INSS stage (p = 0.006) were identified as significant prognostic factors for OS. The induction chemotherapy was not significant for OS (p = 0.18), but significant for EFS (p = 0.08) Treatment with NB84 achieved better mCR, OS and EFS, while OPEC/OJEC had the least treatment-related deaths. In resource-constrained settings, OPEC/OJEC is advised as induction chemotherapy in HR-NB due to less toxicity as reflected in less treatment-related deaths.
