BEACOPP is a chemotherapy regimen for treatment of Hodgkin's lymphoma developed by the (German Hodgkin Study Group ) used for patients in Stages > II or early (IA or IB) with unfavorable risk factors. Patients typically receive treatment in cycles of 21 days with no drugs given on days 15–21.〔(See HD14 Redacted Trial Protocol, available at )〕 There also exists a more intensive regimen with cycles of 14 days. Usually a course of BEACOPP therapy consists of four, sometimes six to eight cycles, or in combination with ABVD. 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 was thought to induce more secondary neoplasias (such as leukemias), although 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.〔 Some consider that the BEACOPP regimen is not generally given in the US for cost reasons: * Twice as many infusion per cycle relative to ABVD; * Requirement for G-CSF support, which is still under patent protection as Neupogen by Amgen in the US until Dec. 12, 2013,〔(【引用サイトリンク】url=http://www.fiercepharma.com/special-reports/neupogen )〕 while Neupogen patent protection in the EU expired in 2008;〔(【引用サイトリンク】url=http://seekingalpha.com/article/846451-amgen-and-its-biosimilar-competitors )〕 * Higher likelihood of adverse events requiring hospitalization, such as infection or acute toxicity; However, BEACOPP delivers approximately 7% points success relative to ABVD for early unfavorable Hodgkin's disease (as measured five-year freedom from treatment failure)〔 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. == Dosing regimen == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BEACOPP」の詳細全文を読む スポンサード リンク
