Epidemiological trends and treatment abandonment of paediatric solid tumours in a nigerian tertiary hospital: a seven-year review (2016-2022).

ABSTRACT

BACKGROUND: Paediatric solid tumours, both benign and malignant, present significant health challenges, particularly in Sub-Saharan Africa where comprehensive data is limited. This study aims to elucidate the prevalence, distribution, and treatment outcomes of paediatric solid neoplasms in a tertiary hospital in South-East Nigeria over a seven-year period. METHODS: A retrospective cohort study was conducted at Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Nigeria. Clinical details and histological slides of confirmed cases from January 2016 to December 2022 were reviewed. Data extraction focused on socio-demographic variables and treatment outcomes, analysed using statistical methods. RESULTS: The study included 293 children diagnosed with solid tumours (58.1% malignant, 41.9% benign), with a female predominance (61.8%). The median age at diagnosis was 12 years. Fibroadenoma was the most common benign tumour (61.8% of benign cases), while non-Hodgkin lymphoma was the predominant malignant tumour (18.2% of malignant cases). Treatment abandonment rates differed significantly between benign (13.8%) and malignant (51.2%) tumours. Significant associations were found between treatment outcomes and factors such as gender (p = 0.0001 for benign tumours), age category (p = 0.0001 for benign tumours), and specific diagnoses (p = 0.0001 for both benign and malignant tumours). CONCLUSION: This study underscores the substantial burden of paediatric solid tumours in South-East Nigeria and highlights the critical need for improved treatment adherence strategies, particularly for malignant cases. The findings emphasize the importance of tailored interventions based on tumour type, age, and gender. These insights can inform future research, policy formulation, and healthcare strategies aimed at enhancing the management and outcomes of paediatric solid neoplasms in resource-limited settings.
