【摘要】 目的:探究PAK4在甲状腺乳头状癌中的表达情况及临床意义。方法:从笔者所在医院甲状腺癌标本库中选取2013-2017年经手术后的组织标本,其中甲状腺乳头状癌(PTC)60例,甲状腺非恶性病例30例。采用免疫组化的方法对PAK4在甲状腺非恶性病例与甲状腺乳头状癌中的表达水平进行检测。结果:在60例PTC中PAK4阳性表达为27例(45.00%),其中强阳性表达12例(20.00%),中等阳性表达15例(25.00%)。PTC中PAK4的阳性表达率为45.00%,显著高于甲状腺良性组织中的6.67%,差异有统计学意义(P<0.05)。PAK4在甲状腺乳头状癌阳性表达和正常表达的性别、年龄、肿瘤大小、是否单发、是否单侧比较,差异无统计学意义(P>0.05);两者腺体外浸润、临床分期、淋巴结转移比较,差异有统计学意义(P<0.05)。结论:PAK4在甲状腺乳头状癌中阳性表达率较高,可能预示存在腺体外浸润、淋巴结转移、疾病Ⅲ或Ⅳ期,为本病的早期诊治提供新的策略。

[Abstract] Objective: To investigate the expression and clinical significance of PAK4 in papillary thyroid carcinoma. Method: From 2013 to 2017, there were 60 cases of papillary thyroid cancer and 30 cases of non malignant thyroid cancer were selected. The expression of PAK4 in non malignant thyroid cases and papillary thyroid carcinoma were detected by immunohistochemistry. Result: A total of 60 PTC patients, the positive expression of PAK4 was 27 cases (45.00%), strong positive expression was 12 cases (20.00%), moderate positive expression was 15 cases (25.00%). The positive expression rate of PAK4 in PTC was 45.00%, which was significantly higher than the non malignant thyroid cancer (6.67%), the difference was statistically significant (P<0.05), there were no significant differences in gender, age, tumor size, single lesion and unilateral expression between positive and normal expression of PAK4 (P>0.05). There were significant differences in extraglandular infiltration, clinical stage and lymph node metastasis between the two groups (P<0.05). Conclusion: The positive expression of PAK4 in papillary thyroid carcinoma may indicate the presence of extraglandular infiltration and lymph node metastasis to Ⅲ or Ⅳ of the disease, providing a new strategy for the early diagnosis and treatment of the disease.

甲狀腺癌恶性程度不高,因此临床不被重视,且其相关诊断发现不了较小的肿瘤。甲状腺乳头状癌(PTC)占其病理类型的80%,为防止临床症状被忽视所致PTC至疾病中晚期,死亡率增高,因此采取适宜的早期诊断尤为关键[1]。P21激活激酶4(PAK4)在当今已被证实,与食管癌、肝癌、胰腺癌、直肠癌及乳腺癌等肿瘤疾病的发生发展、侵袭转移具有密切联系[2]。PAK4是在RAS驱动肿瘤形成通路中具有关键作用的介导蛋白之一,能够刺激MAPK通路[3]。曾有研究表明,PAK4与肿瘤恶性程度具有密切联系,其表达水平提高,提示肿瘤预后不良[4]。因此,本研究就PAK4在甲状腺乳头状癌中的表达情况进行研究,如下。
