BEACOPP is a chemotherapy regimen for treatment of Hodgkin lymphoma developed by the German Hodgkin Study Group[1] used for patients in Stages > II or early (IA or IB) with unfavorable risk factors.
In some countries BEACOPP still is experimental, in others (e.g. Germany and Austria) it is a standard therapy.
In the United States, ABVD (or Stanford V) is generally given instead, because BEACOPP is perceived by practicing oncologists to have the potential to induce more secondary neoplasias (such as leukemias).
However, the final results from the GHSG HD14 trial indicate that "there were no overall differences in treatment-related mortality or secondary malignancies" of BEACOPP relative to ABVD.
[2] Oncologists in the US have also used the BEACOPP regimen relatively less for cost reasons: However, BEACOPP delivers approximately 7% points success relative to ABVD for early unfavorable Hodgkin's disease (as measured five-year freedom from treatment failure)[2] and 12% points greater success relative to ABVD for advanced Hodgkin's disease (Stage IIB with risk factors or stages III and IV) as measured by seven-year freedom from treatment failure.
