摘要 胶质瘤是最常见的原发性脑肿瘤。目前的组织病理学诊断主要依据肿瘤细胞形态学上与各类胶质细胞的相似性将其分为星形细胞肿瘤、少枝胶质细胞肿瘤、混合性少枝一星形细胞肿瘤和室管膜源性肿瘤,然后进一步根据形态学特征划分为I-Ⅳ级(星形细胞肿瘤I-Ⅳ级,少枝胶质细胞肿瘤Ⅱ一Ⅲ级,混合性肿瘤Ⅱ-Ⅳ级)。目前组织学诊断仍是胶质瘤诊断和分级的金标准。然而,组织形态学相同的肿瘤预后仍可以有很大不同。分子遗传学研究结果显示组织学上相似的肿瘤中存在多个不同的分子亚型,各亚型临床病程和治疗反应可以有很大差别。随着近年来对脑胶质瘤诊断、预后和治疗反应预测的分子标志物的深入研究,我们对疾病的理解随之逐步加深,对患者的治疗正在向针对每个个体分子特征的个体化治疗转化。胶质瘤的分子病理检测在临床上的常规应用逐渐成为迫切的实际需求。现对脑胶质瘤分子病理的近期进展进行总结,并对未来进行展望。
