软骨肉瘤(CHS)是一种恶性软骨形成肿瘤,通常发生在长骨和骨盆骨的髓管内。仅根据形态学特征,正确诊断CHS可能很困难,因此,诊断CHS时必须结合放射学和临床病理特征。 CHS 的预后与组织学分级密切相关,但组织学分级可能具有主观性,且观察者间差异较大。在本文中,我们介绍了传统 CHS 的组织学分级系统以及临床病理学和放射学结果。还介绍了 CHS 的亚型,例如去分化、间充质和透明细胞 CHS。此外,我们介绍了最新的细胞遗传学和分子遗传学发现,以扩大我们对中枢性低通气综合症生物学的理解。细胞分化、增殖和细胞信号传导的新标记可能在不久的将来提供重要的治疗和预后信息。
Chondrosarcoma (CHS) is a malignant cartilage-forming tumor and usually occurs within the medullary canal of long bones and pelvic bones. Based on the morphologic feature alone, a correct diangosis of CHS may be difficult, Therefore, correlation of radiological and clinicopathological features is mandatory in the diagnosis of CHS. The prognosis of CHS is closely related to histologic grading, however, histologic grading may be subjective with high inter-observer variability. In this paper, we present histologic grading system and clinicopathological and radiological findings of conventional CHS. Subtypes of CHSs, such as dedifferentiated, mesenchymal, and clear cell CHSs are also presented. In addition, we introduce updated cytogenetic and molecular genetic findings to expand our understanding of CHS biology. New markers of cell differentiation, proliferation, and cell signaling might offer important therapeutic and prognostic information in near future.
