【摘要】:目的: 探讨超声引导下粗针穿刺活检评价微钙化在甲状腺癌诊断中的价值。 方法: 1.对62例患者伴有钙化的甲状腺结节疑似病灶行超声引导下粗针穿刺活检,活检结果与手术病理结果对照,分析穿刺活检结果与术后病理结果是否有差异。 2.根据结节内钙化灶的大小,可将其分为粗钙化(1mm)和微钙化(≤1mm)比较二者在甲状腺良恶性结节中是否有差异。 结果: 1.超声引导下粗针穿刺活检准确率96.7%,敏感性96%,特异性100%。 2.微钙化诊断甲状腺癌的特异性为95.0%,微钙化在良性肿瘤与甲状腺癌中的发生率比较差异有统计学意义。 3.年龄45岁与≥45岁患者发生甲状腺癌伴钙化者在甲状腺肿瘤中的比例分别为为90.2%和61.9%,二者有统计学差异。 4.男性甲状腺癌伴钙化者发生率76%,女性甲状腺癌伴钙化者发生率83.8%,二者在统计学上无明显差异。 结论: 1.超声引导下甲状腺粗针穿刺活检具有较高的准确率、敏感性和特异性。 2.对年龄45岁伴有钙化,尤其是微钙化的甲状腺结节患者发生恶性危险性增高,应进一步考虑穿刺活检,明确病理诊断. 3.微钙化是甲状腺癌的特征性征象,但微钙化并非甲状腺癌所特有。超声引导下粗针穿刺活检可以弥补高频彩超的不足,显著提高甲状腺癌的早期诊断率。对甲状腺癌具有极高的术前诊断价值,对甲状腺结节的治疗具有重要的指导意义。
