Chordomas, arising from notochord remnants, are rare neoplasms with aggressive growth patterns despite their histologically low-grade nature. This review explores their embryological origins, molecular markers like brachyury, and genetic alterations driving pathogenesis. Diagnosis relies on advanced imaging and biopsy confirmation due to overlapping features with chondrosarcoma. The WHO classification distinguishes conventional, dedifferentiated, and poorly differentiated chordomas, each with distinct prognostic implications. Recent genomic analyses uncovered recurrent mutations in PI3K signaling pathways and chromatin remodeling genes, informing prognostic models. Surgery remains the cornerstone of treatment, though adjuvant radiation complements surgical resection. Although chordomas are generally considered refractory to medical therapy, emerging targeted molecular strategies show potential promise in ongoing trials. This review aims to provide a concise yet comprehensive overview of chordomas, guiding clinicians in diagnosis, treatment, and prognostication for improved patient outcomes.
脊索瘤起源于脊索残余物,是一种罕见的肿瘤,具有侵袭性生长模式,尽管其组织学上为低级别。本综述探讨了其胚胎起源、分子标志物如 brachyury 以及导致发病机制的遗传改变。由于与软骨肉瘤具有重叠特征,因此诊断依赖于先进的影像学和活检确认。世界卫生组织分类区分了常规、去分化和低分化脊索瘤,每种都有不同的预后意义。最近的基因组分析揭示了 PI3K 信号通路和染色质重塑基因的反复突变,为预后模型提供了信息。手术仍然是治疗的基石,尽管辅助放疗补充了手术切除。虽然脊索瘤通常被认为对药物治疗有抗性,但新兴的靶向分子策略在正在进行的试验中显示出有希望的前景。本综述旨在为脊索瘤提供简洁而全面的概述,指导临床医生进行诊断、治疗和预后,以改善患者的预后。
