Thyroid:原发性甲状腺淋巴瘤与甲状腺自身免疫病之间的关系

在大多数病例中,HT伴PTL,GD伴PTL较为少见(1.8%)。GD患者PTL各病理亚型所占比例及预后与HT及无AITD患者无明显差异。

原发性甲状腺淋巴瘤(PTL)主要发生在桥本甲状腺炎(HT)患者中,而在Graves病(GD)患者中则较为罕见。

近日,甲状腺疾病领域权威杂志Thyroid上发表了一篇研究文章,该研究的目的是调查PTL患者的临床特征、病理结果和长期结局,根据是否存在GD、HT或无自身免疫性甲状腺疾病(AITDs)进行分组。由于与PTL的关系了解十分有限GD组引起了研究者极大的兴趣。

在这项单中心回顾性队列研究中,研究人员回顾了1979年8月至2021年10月期间诊断为PTL的所有患者的病历,并根据患者是否存在HT、GD或无AITD对患者进行了分类。病理标本按世界卫生组织的标准进行分类。分期根据AnnArbor分级进行。

在42年期间,498名参与者被诊断为PTL。中位年龄为68岁(四分位差范围为61-76岁),221例患者为IE期,而其余277例患者为IIE期。PTL患者中,431例(86.6%)诊断为HT,9例(1.8%)诊断为GD,58例(11.6%)无AITDs。9例GD患者抗甲状腺球蛋白抗体和/或抗甲状腺过氧化物酶抗体均呈阳性。所有GD患者均接受抗甲状腺药物治疗。PTL合并GD组与所有PTL组(p=0.51)、PTL合并HT组(p=0.51)、PTL合并无AITDs组(p=0.48)各亚型的比例差异无统计学意义。中位随访时间为诊断PTL后6.2年(四分位间距为3.0-10.7年)。Kaplan-Meier曲线分析显示,PTL合并GD患者与HT患者的总生存期和无事件生存期(p=0.37)、PTL合并GD患者与无AITDs患者的总生存期和无事件生存期(p=0.43)均无显著差异。

由此可见,在大多数病例中,HT伴PTL,GD伴PTL较为少见(1.8%)。GD患者PTL各病理亚型所占比例及预后与HT及无AITD患者无明显差异。
