In patients with relapsed/refractory Hodgkin lymphoma, treatment with immune checkpoint inhibitors (ICIs), nivolumab and pembrolizumab, leads to 20-30% of complete remission (CR) rate. This means that for the majority of patients a consolidation strategy is usually offered, in order to reduce relapse rate.~Strategies to improve CR rates should therefore be implemented, including combination treatments. In solid tumors, the combination of ICIs and radiotherapy led to higher response rates without mjor toxicity concerns. Radiotherapy is an effective therapeutic option already used in Hodgkin lymphoma patients, also in the setting of relapsed/refractory disease. In his observational study we aim to evaluate the efficacy and safety of ICIs and radiotherapy administered in combination in patients with relapsed/refractory Hodgkin lymphoma.
This is an observational retrospective study to investigate the efficacy and safety of the treatment with an immune checkpoint inhibitor (nivolumab or pembrolizumab) in combination with radiotherapy in patients with relapsed/refractory classical Hodgkin lymphoma.
