许多血液学家旨在联系白血病的预后而将急性白血病再分成不同亚型。然而这些分类诊断的正确性需经集体讨论才能确定。英国南威尔士由5名血液学家组成一个小组,采用一个较不复杂的白血病分类,检查了456例诊断为白血病或骨髓瘤病人的血片和骨髓片。开始时,互不商议,提出各自的分类意见;如有不同意见,继经集体讨论以作出最后的诊断。作者们经集体研究,将白血病分为:急性髓性白血病、急性淋巴细胞白血病、慢性淋巴细胞白血病、慢性粒细胞白血病及其他白血病;急性髓性白血病又分为6个亚型:急性粒细胞白血病(M_2~*)、急性粒单细胞白血病(M_4~*)、急性未分化细胞白血病(M_1~*)、
Many hematologists aim to subdivide acute leukemia into different subtypes in relation to the prognosis of leukemia. However, the correctness of the diagnosis of these categories subject to collective discussion to determine. A group of five hematologists in South Wales, UK, used a less complex classification of leukemias to examine blood and bone marrow pieces from 456 patients diagnosed with leukemia or myeloma. In the beginning, they would not discuss with each other and put forward their own disagreements; if there is any disagreement, they will go through a group discussion to make a final diagnosis. The authors collectively classified leukemia as acute myeloid leukemia, acute lymphoblastic leukemia, chronic lymphocytic leukemia, chronic myelogenous leukemia and other leukemias; acute myelogenous leukemia is subdivided into six subtypes: acute myeloid leukemia (M_2 ~ *), acute myelomonocytic leukemia (M_4 ~ *), acute undifferentiated leukemia (M_1 ~ *),
