Optimal Therapy for Early-Stage Hodgkin’s Lymphoma: Risk Adapting, Response Adapting, and Role of Radiotherapy

Purpose of Review: The aim of this article is to discuss the current role of radiotherapy (RT) for early-stage Hodgkin’s lymphoma (HL) in the context of risk-adapted and response-adapted treatment strategy, and describe changes in RT technical approach. Recent Findings: In low-risk patients, RT could be omitted but, at the price of a lower progression-free survival, and its role is still debated. Ongoing trials are combining new agents with chemotherapy alone or response-adapted combined modality therapy, and results are awaited. Modern RT incorporates lower doses and smaller fields, together with the implementation of sophisticated delivery techniques aimed to reducing the dose to critical structures such as the heart. Summary: The role of RT for early-stage HL is still under debate, and new combinations are emerging; an individualized approach should be recommended, considering all RT technical opportunities to minimize toxicity while maintaining efficacy.
