【摘 要】 目的 对甲状腺乳头状癌的病理学形态进行总结,并分析免疫组织化学指标Galectin-3、 CK19、 HBME-1、AAT及CD56的在甲状腺乳头状癌中的表达情况,探讨其对诊断甲状腺乳头状癌的意义。方法 选取甲状腺乳头状癌227例为观察组,选取结节性甲状腺肿168例為对照组,在病理学研究基础上,应用免疫组织化学染色,分别检测两组组织表达Galectin-3、 CK19、 HBME-1、AAT及CD56的情况。结果 甲状腺乳头状癌病理学形态表现为:真性乳头的形成(72.24%)和(或)特征性的核变化,包括核增大、出现核仁(98.23%),核排列重叠拥挤、轮廓不规则(96.47%),毛玻璃样核(88.54%),核沟(73.56%),核内假包涵体(28.63%),砂粒体(16.30%),肿瘤纤维化(62.99%)。免疫组织化学染色提示甲状腺乳头状癌中Galectin-3(95.15%)、CK19(99.19%)、HBME-1(92.09%)、AAT(96.48%)阳性表达率均显著高于结节性甲状腺肿,且以强阳性及中等阳性为主,CD56(3.08%)阳性表达率显著低于结节性甲状腺肿。结论 病理学光镜诊断基础上联合免疫组织化学标记能显著提高甲状腺乳头状癌诊断的敏感度及准确性。

Abstract Objective:Summarize the pathology form and analysis to the expression of Galectin-3, CK19, HBME-1, AAT and CD56 in papillary thyroid carcinoma,in order to investigate the importance of diagnosis of papillary thyroid carcinoma.Method:227 cases of papillary thyroid carcinoma were selected as the observation group, and 168 cases of nodular goiter were selected as the control group.On the basis of pathological study,we used immunohistochemical staining to analysis the expressions of Galectin-3, CK19, HBME-1, AAT and CD56 in the two groups.Result:The pathological morphology of papillary thyroid carcinoma is characterized by true nipple formation(72.24%)and(or) characteristic nuclear change,which including enlargement of the nucleus and presence of nucleoli (98.23%),overlapping, crowded, and irregularly shaped contours (96.47%),frosted glass nucleus (88.54%),nuclear groove (73.56%), intranuclear inclusion bodies (28.63%),sand bodies (16.30%),tumor fibrosis (62.99%).IHC staining showed Galectin-3 in papillary thyroid carcinoma (95.15%), CK19 (99.19%), HBME-1 (92.09%), AAT (96.48%) positive expression rate was significantly higher than in nodular goiter, and most of them were strong positive or moderate positive, CD56 (3.08%) positive expression rate was significantly lower than in nodular goiter. Conclusion:Pathological and light microscopic diagnosis combine with immunohistochemical staining can significantly improve the sensitivity and accuracy of the diagnosis of papillary thyroid carcinoma.

甲状腺乳头状癌是全世界范围内地方性甲状腺肿非流行区域最常见的甲状腺上皮源性恶性肿瘤【1】。近几年来,其发病率在我国呈上升趋势,约占整个甲状腺肿瘤的70%【2】,该病通常呈惰性经过,预后较好,10年生存率高达80%以上【3】。在临床病理诊断过程中,经典的甲状腺乳头状癌依据其独特的核特征,可以做出准确的病理诊断,但由于乳头状癌有许多亚型及核的特征不典型时不易做出准确的判断,需要借助必要的辅助诊断手段来实现,临床病理诊断过程中通常借助免疫组化染色辅助诊断。鉴于此,本文对227例甲状腺乳头状癌的病理学形态进行总结,并探讨Galectin-3、CK19、HBME-1、AAT及CD56这5个免疫组织化学指标在甲状腺乳头状癌病理诊断中的意义。
