Machine Learning to Predict Interim Response in Pediatric Classical Hodgkin Lymphoma Using Affordable Blood Tests.

Purpose: Response assessment of classical Hodgkin lymphoma (cHL) with positron emission tomography-computerized tomography (PET-CT) is standard of care in well-resourced settings but unavailable in most African countries. We aimed to investigate correlations between changes in PET-CT findings at interim analysis with changes in blood test results in pediatric patients with cHL in 17 South African centers.

Methods: Changes in ferritin, lactate dehydrogenase (LDH), erythrocyte sedimentation rate (ESR), albumin, total white cell count (TWC), absolute lymphocyte count (ALC), and absolute eosinophil count were compared with PET-CT Deauville scores (DS) after two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine in 84 pediatric patients with cHL.

Evaluating the baseline survival outcomes of the "six Global Initiative for Childhood Cancer index cancers" in Africa.

Limited survival data for the six Global Initiative for Childhood Cancer (GICC) priority cancers are available in Africa. Management of pediatric malignancies in Africa is challenging due to lack of resources, setting-specific comorbidities, high rates of late presentation and treatment abandonment. Reporting of outcome data is problematic due to the lack of registries.

Pediatric cancer care in Africa: SIOP Global Mapping Program report on economic and population indicators.

Introduction: Inalignment with the World Health Organization (WHO) Global Initiative for Childhood Cancer (GICC), the International Society of Pediatric Oncology initiated a program to map global pediatric oncology services. As survival rates in Africa are low and data are scant, this continent was mapped first to identify areas with greatest need.

Methods: Beginning November 2018, an electronic survey was sent to all known stakeholders, followed by email communications and internet searches to verify data.

Pediatric cancer care in Africa: SIOP Global Mapping process.

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).

Prognostic factors affecting survival in children and adolescents with HIV and Hodgkin lymphoma in South Africa.

South African children with Hodgkin lymphoma (HL) and human immunodeficiency virus (HIV) have low 5-year overall survival (OS) rates. In this retrospective multicenter study, 271 South African pediatric patients with HL were studied to determine OS and prognostic factors in those with HIV and HL. Univariate risk factor analysis was performed to analyze prognostic factors.

Travel burden and clinical presentation of retinoblastoma: analysis of 1024 patients from 43 African countries and 518 patients from 40 European countries.

Background: The travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, the most common childhood eye cancer. We aimed to investigate the travel burden and its impact on clinical presentation in a large sample of patients with retinoblastoma from Africa and Europe.

Methods: A cross-sectional analysis including 518 treatment-naïve patients with retinoblastoma residing in 40 European countries and 1024 treatment-naïve patients with retinoblastoma residing in 43 African countries.

Global Retinoblastoma Presentation and Analysis by National Income Level.

Importance: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale.

Enough is not enough: Medical students' knowledge of early warning signs of childhood cancer.

Background: The reported incidence of childhood cancer in upper-middle-income South Africa (SA) is much lower than in high-income countries, partly due to under-diagnosis and under-reporting. Documented survival rates are disturbingly low, prompting an analysis of potential factors that may be responsible.

Objectives: To determine final-year medical students' level of knowledge of early warning signs of childhood cancer and whether a correlation existed between test scores and participants' age, gender and previous exposure to a person with cancer.

Treatment outcomes of children with Hodgkin lymphoma between 2000 and 2010: First report by the South African Children's Cancer Study Group.

Background: Children with Hodgkin lymphoma (HL) have excellent survival rates in high-income countries, but there are minimal outcome data in South African patients. Differing approaches to treatment are used in centres across South Africa, and the South African Children's Cancer Study Group (SACCSG) embarked on a programme to audit outcomes to improve survival rates.

Patients And Methods: A multicentre study was conducted to analyse outcomes and prognostic factors of children with HL in South Africa.

Paediatric cancer survivors demonstrate a high rate of subclinical renal dysfunction.

Background: Clinical manifestations of renal dysfunction in childhood cancer survivors include hypertension, proteinuria, tubulopathy (and its biochemical consequences) and renal insufficiency. This study aimed to determine the factors associated with renal dysfunction in paediatric cancer survivors at a single centre in Johannesburg.

Procedure: A descriptive cross-sectional study was performed on 130 cancer survivors between 2 and 18 years of age.
