概述

甲状腺嗜酸细胞癌是一种影响甲状腺的罕见癌症。

甲状腺是位于颈底部的一个蝴蝶状腺体。它所分泌的激素对于调节身体的新陈代谢至关重要。

甲状腺嗜酸细胞癌也称甲状腺嗜酸恶性上皮癌或嗜酸性细胞癌。甲状腺嗜酸细胞癌是影响甲状腺的几种癌症之一。

甲状腺嗜酸细胞癌可能比其他类型的甲状腺癌更具侵袭性。最常见的治疗方法是手术切除甲状腺。

症状

甲状腺嗜酸细胞癌并不总是会引起症状,有时会在体格检查或影像学检查中由于其他原因而被发现。

甲状腺嗜酸细胞癌的体征和症状可能包括:

  • 颈部有肿块,就在喉结的下方
  • 颈部或咽喉疼痛
  • 声音嘶哑或有其他变化
  • 气短
  • 吞咽困难

这些体征和症状并不一定意味着您患有甲状腺嗜酸细胞癌。可能是其他医学病症的征兆,例如甲状腺炎症或甲状腺的非癌性增大(甲状腺肿)。

何时就诊

如果您有任何体征或症状令您担心,请与医生约诊。

病因

目前尚不清楚引起甲状腺嗜酸细胞癌的原因。

医生知道,癌症始于细胞的 DNA 错误,DNA 是一种包含人体生化过程指令的遗传物质。当 DNA 发生改变或受损时,这些基因可能无法正常工作,导致细胞无线增殖,最终形成癌细胞团(恶性肿瘤)。

风险因素

增加患甲状腺癌风险的因素包括:

  • 身为女性
  • 高龄
  • 有头部和颈部放射治疗史

并发症

甲状腺嗜酸细胞癌可能的并发症包括:

  • 吞咽和呼吸问题。如果肿瘤不断长大并压迫食管和气管,就会发生这类问题。
  • 癌症扩散。甲状腺嗜酸细胞癌可扩散(转移)到其他组织和器官,让治疗和康复变得更加困难。
