Comparison of Outcomes by Age of Patients with Limited Stage Hodgkin Lymphoma Treated with ABVD Alone; A Secondary Analysis of the Canadian Cancer Trial Group HD.6 Trial

Introduction: Management options for individuals with early-stage Hodgkin lymphoma (HL) include combined modality therapy (CMT), and chemotherapy alone. The HD.6 randomized phase III trial, in which ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) alone was compared with radiation based therapy, comprises the largest prospectively collected data set of individuals with limited stage HL treated with ABVD alone with long-term follow-up [Meyer JCO 2005, NEJM 2012]. Adolescents and young adults (AYAs) with cancer are considered a vulnerable population, in part due to unique psychosocial challenges and distinct disease biology. The most common cancer observed among AYAs is HL. However, studies focusing specifically on AYAs diagnosed with limited stage HL are scarce. We sought to evaluate the impact of age on outcomes of individuals with stage IA and IIA non-bulky HL, treated with ABVD alone.
