Childhood cancer presents significant challenges in low- and middle-income countries (LMICs), as survival rates remain substantially low. Supportive care, including nutritional support and infection prevention plus management, is crucial in improving outcomes of childhood cancer patients. To develop evidence-based interventions improving supportive care and survival, insight is needed into local prevalences of malnutrition, colonisation and infections, their association with clinical outcomes and the attitude of parents or legal guardians towards nutritional care and infection prevention. The overall aim of this prospective cohort study is to identify modifiable nutritional and infection-related determinants of clinical outcomes at 6 months in children with cancer (1–15 years of age) treated with curative intent at the Paediatric Oncology ward of the Shoe4Africa Children’s Hospital at the Moi Teaching and Referral Hospital in Eldoret, Kenya.

We will conduct a prospective cohort study on 150 children aged 1–15 years who are newly diagnosed with cancer and treated with curative intent. During 6 months of follow-up, we will collect clinical data, perform nutritional assessments and monitor pathogen exposure, colonisation and infections. Parents or legal guardians will receive one questionnaire to assess attitudes towards supportive care. Six-month mortality is the primary outcome. Other outcomes include the prevalence and characteristics of malnutrition, rectal colonisation with bacterial and fungal pathogens, infections and neutropenic fever episodes. Statistical analyses will include descriptive statistics, chi-square tests, logistic regression and thematic analysis.

The Institutional Research and Ethics Committee has approved the study protocol (FAN: 0004674, protocol version 1.0). Informed consent from parents or legal guardians and assent from children ≥12 years will be obtained. Findings will be disseminated through peer-reviewed publications, presentations at academic conferences and engagement with local and national policymakers and stakeholders. Data from this study could guide the development of locally informed, evidence-based supportive care interventions, with the ultimate goal to improve overall survival for children with cancer in LMICs.

Each year, an estimated 1700 children should be diagnosed with cancer in western Kenya, with leukaemia making up nearly one-third of cases. However, far fewer are actually diagnosed, highlighting significant delays or errors in diagnosis. Flow cytometry, which the WHO considers essential for leukaemia diagnosis, remains underused across sub-Saharan Africa due to high costs, outdated equipment and a lack of trained personnel. In Kenya, decades-old cytometers have been adapted for leukaemia detection, but these systems are now outdated. Newer platforms, such as simplified single-tube multiparametric assays, provide a scalable and sustainable alternative. This study presents a protocol to evaluate the accuracy of diagnosis and the potential for implementing a streamlined flow cytometry assay using peripheral blood, supported by a regional educational initiative.

This prospective, mixed-methods implementation study has three aims: (1) to assess the concordance between the Beckman Coulter ClearLLab 10C gold standard 4-tube assay and the streamlined ClearLLab LS 1-tube assay using paired bone marrow and peripheral blood samples; (2) to evaluate the feasibility of peripheral facility referrals and transport logistics with couriered peripheral blood samples from referring sites across western Kenya; and (3) to measure training effectiveness and knowledge gain through a multimodal educational programme using the Project ECHO (Extension for Community Healthcare Outcomes) model. Up to 300 patients at Moi Teaching and Referral Hospital in Eldoret, Kenya, will be enrolled in Aim 1. A separate sample of 100 patients from peripheral facilities will be included in Aim 2. Surveys, knowledge assessments and structured interviews will be used to evaluate training impact under Aim 3. Diagnostic concordance, sensitivity, specificity and knowledge gain will be measured through appropriate quantitative and qualitative methods.

The protocol has received approval from institutional ethics committees at Moi University, MTRH and Indiana University. De-identified data will be analysed and shared through peer-reviewed publications, stakeholder presentations and educational platforms.
