Awareness, widespread availability, and routine use of sequencing techniques in work-up of myelodysplastic syndromes and acute myeloid leukemia have facilitated increased recognition of these entities arising in a background of germline predisposition disorders (GPD).
The latest revisions to the WHO classification of myeloid neoplasms incorporate "myeloid neoplasms with germline predisposition" as a separate entity due to the therapeutic implications of this diagnosis. It has become apparent that some of these entities have unique recognizable morphologic findings that can be challenging to interpret at time. Hence, much needs to be studied, posing a new layer of complexity to hematopathologists and oncologists. A thorough understanding of cytogenetic and molecular findings during disease evolution is essential. Consequently, hematopathologists and molecular pathologists play an increasing role in recognition of bone marrow morphologic features that help in recognition of underlying GPD, monitoring, and prompt identification of progression.
在骨髓增生异常综合征和急性髓系白血病的检查中,测序技术的认识、广泛可用性和常规使用,促进了对这些以种系易患性疾病(GPD)为背景的实体的认识增加。
由于该诊断的治疗意义,世界卫生组织(WHO)髓系肿瘤分类的最新修订将“具有种系易患性的髓系肿瘤”作为一个单独的实体。显然,其中一些实体具有独特的可识别形态学发现,在某些时候可能难以解释。因此,需要进行大量的研究,这给血液病理学家和肿瘤学家带来了新的复杂性。彻底了解疾病演变过程中的细胞遗传学和分子发现至关重要。因此,血液病理学家和分子病理学家在识别有助于识别潜在 GPD、监测和及时识别进展的骨髓形态特征方面发挥着越来越重要的作用。
