The standard chemotherapy for Hodgkin lymphoma is called ABVD which is a combination of 4 chemotherapy drugs (doxorubicin, bleomycin, vinblastine, and dacarbazine). The number of cycles of ABVD chemotherapy Hodgkin lymphoma patients receive is about 4-6 cycles. In addition to the ABVD chemotherapy, patients with Hodgkin lymphoma will routinely receive radiation therapy. The use of chemotherapy and radiation may cause long term treatment related side effects such as heart problems and other cancers. Researchers are trying to find if combining ABVD chemotherapy with new drugs and reducing the number of ABVD chemotherapy cycles given is just as effective as the standard Hodgkin treatment.
