Hodgkin Lymphoma in Adolescent and Young Adults: Real-World Data from a Single Tertiary Cancer Center in India

Purpose:There is lack of consensus on management of adolescent and young adult (AYA) Hodgkin lymphoma with respect to chemotherapy approach (adult or pediatric). Hence we sought to evaluate the efficacy and safety of Adriamycin, Bleomycin, Vinblastine and Dacarbazine (ABVD) chemotherapy in AYA Hodgkin lymphoma. Patients and Methods:It is a retrospective, observational, single-center study. From January 2013 to December 2016, all consecutive patients with AYA (15-25 years, all stages) were analyzed. The primary endpoint of the study was event-free survival (EFS). Secondary endpoints were complete response rates (CR) and overall survival (OS). Results:A total of 220 patients (70% men) with median age 20 years were evaluated. A significant proportion of patients had adverse features such as stage III/IV disease (63%), bulky disease (63%), extranodal involvement (37%), and marrow involvement (22%). After two cycles and end of therapy, 77% patients achieved complete response. Primary progressive disease was seen in 6% patients. With a median follow-up of 2.6 years, 19 (8.6%) patients relapsed, 1 patient developed second malignancy, and 6 patients died. Three-year EFS and OS were 81.3% and 97%, respectively. Bleomycin-induced lung injury was seen in 16% patients. On multivariate analysis stage at presentation, bone marrow involvement, partial response at interim positron emission tomography and International prognosis score (IPS) >3 were predictors of poor EFS. Conclusion:ABVD is an effective and safe regimen in AYA Hodgkin lymphoma. Advanced disease with high IPS (>3) score needs an early escalation approach to escBEACOPP regimen.
