Characteristics of relapsed and refractory paediatric Hodgkin lymphoma; a 10-year retrospective study of an LMIC

With conventional standard treatment modalities, children and adolescents with Hodgkin lymphoma (HL) have long-term overall survival rates of over 90%. However, primary refractory disease may occur in 5%-10% of HL patients, while relapse occurs in 5%-10% of patients with early stage disease and up to 30% in an advanced stage. This retrospective study evaluated patient characteristics in cases of HL relapse and refractory and their response to second-line treatment of standalone chemotherapy or in combination with radiotherapy.
