Treatment abandonment in children with Wilms tumor at a national referral hospital in Uganda.

INTRODUCTION: The incidence of pediatric Wilms tumor (WT) is high in Africa, though patients abandon treatment after initial diagnosis. We sought to identify factors associated with WT treatment abandonment in Uganda. METHODS: A cohort study of patients  25 cm (OR 2.67, 95% CI 1.05-6.81). CONCLUSIONS: Children with WT in Uganda frequently abandon care during neoadjuvant therapy, particularly those with large tumors with poor response. Further investigation into the factors that influence treatment abandonment and a deeper understanding of tumor biology are needed to improve treatment adherence of children with WT in Uganda.
