Palliating hematologic oncologic emergencies with radiation in the age of targeted systemic therapies: three illustrative cases

Résumé fourni par la source

Hematologic oncologic emergencies with an urgent indication for radiation are a relatively routine occurrence for the radiation oncologist. As patients are living longer and have multiple treatment options for their relapsed or refractory diseases, it is important that palliative treatments avoid precluding patients from or delaying next-line potentially curative treatments wherever possible. We highlight the following experiences from our clinical practice: newly diagnosed plasma cell disease causing cord compression; life threatening cutaneous lymphoma with tumors covering the majority of the body surface area; and relapsed/refractory diffuse large B-cell lymphoma (DLBCL) requiring bridging radiation to a mass impinging on the brachial plexus combined with chimeric antigen receptor (CAR)-T cell therapy. In each case, urgent palliative radiation was utilized, but the approaches were nuanced, with careful consideration of subsequent potential therapies and how the current course of radiation should be tailored for the best interplay with the overall treatment course and trajectory of the disease. With the rapid development of new therapies, it can be difficult to stay up to date on the most recent practice guidelines. Drawing on hematologic-specific guidelines, such as those provided by the International Lymphoma Radiation Oncology Group, and disease site experts can aid in ensuring patients are appropriately palliated and eligible for future therapies.
