Despite this, treatment outcome in the elderly patient is not comparable to that of younger people and the disease is a different entity in older people where different considerations enter into treatment decisions.Recently, two novel targeted drugs have been developed for relapsing and refractory HL patients; Brentuximab vedotin, a CD30 antibody conjugated with a cytotoxic component MMAE, and the checkpoint inhibitors, Nivolumab and Pembrolizumab. This has been an important step in the treatment  for the few, but still existing refractory patients. For Hodgkin lymphomas, radiation oncologists typically use external beam radiation therapy (sometimes shortened to EBRT or XRT). Radiation oncologists deliver external beam radiation therapy to the lymphoma from a machine called a linear accelerator which produces high energy X-rays and electrons. People usually describe treatments as painless and similar to getting an X-ray. Treatments last less than 30 minutes each. For lymphomas, there are a few different ways radiation oncologists target the cancer cells. Involved site radiation is when the radiation oncologists give radiation only to those parts of the persons body known to have the cancer. Very often, this is combined with chemotherapy. Radiation therapy directed above the diaphragm to the neck, chest or underarms is called mantle field radiation. Radiation to below the diaphragm to the abdomen, spleen or pelvis is called inverted-Y field radiation. Total nodal irradiation is when the therapist gives radiation to all the lymph nodes in the body to destroy cells that may have spread.
