新世纪伊始,世界卫生组织(WHO)正式颁布了系列丛书《WHO肿瘤分类》,其中《造血和淋巴系统肿瘤分类》简明扼要地规范了近百年来人们对恶性血液病(“血癌”)的不同命名、分类及认识,特别是关于骨髓增生异常综合征(MDS)--这个刚命名20余年的血液病的新分类标准,引起了界内学者的极大关注。 At the beginning of the new century, the World Health Organization (WHO) formally promulgated a series of WHO Classification of Tumors, in which “Classification of Hematopoietic and Lymphatic System Tumors” concisely and normatively describes people’s opinions on the hematological malignancies (“blood cancers”) in the recent one hundred years. The different nomenclature, classification and understanding, especially about myelodysplastic syndrome (MDS), a new taxonomy of blood diseases just named for more than 20 years, aroused great concern of scholars in the field.
