摘要
目的 探讨甲状腺乳头状癌 C D44v6 , E G F R 的表达与淋巴结转移的关系。方法 应用免疫组化 A B C 法对40 例有颈淋巴结转移的甲状腺乳头状癌( P T C+ L N M) ,44 例无颈淋巴结转移的甲状腺乳头状癌( P T C) ,30 例甲状腺瘤( T A) 和30 例正常甲状腺组织( N T) 进行了 C D44v6 ,, E G F R 检测。结果 84 例甲状腺乳头状癌 C D44v6 , E G F R 的阳性率分别为63 .1 % 和54 .8 % ; P T C+ L N M 组的 C D44v6 , E G F R 阳性率显著高于 P T C 组, T A 组和 N T组者( P< 0 .05 , P< 0 .01) 。甲状腺乳头状癌中 C D44v6 , E G F R 的表达有显著的正相关( P< 0 .01) 。联用 C D44v6 , E G F R 的阳性表达判断甲状腺乳头状癌颈淋巴结转移的灵敏度和阳性预测值比单一使用者高。结论 (1) C D44v6 , E G F R 的阳性表达与甲状腺乳头状癌的颈淋巴结转移密切相关, C D44v6 , E G F R 有助于甲状腺乳头状腺癌淋巴结转移,并在转移过程中起协同作用。(2) 联用 C D44v6 , E G F R 可作为甲状腺乳头状?
Objective To study the relation between the cervical lymph node metastasis (LNM) and expression of CD44v6 and EGFR in papillary thyroid carcinoma (PTC). Methods 40 cases of PTC with LNM, 44 papillary thyroid carcinomas without LNM, 30 thyroid adenoma (TA) and 30 normal thyroids (NT) were studied by ABC immunohistochemical method. Results The positive rates of expression of CD44v6, a variant type of cellular adhesive factor CD44, and epidermal growth factor receptor (EGFR) in PTCs were 63.1% and 54.8% respectively, higher positive rates of CD44v6 and EGFR in group PTC + LNM than that in group PTC, TA and NT (P<0.05, P<0.01). There was a positive association between expression of CD44v6 and EGFR in the 84 cases of PTCs (P<001), and parallel use of CD44v6 and EGFR had higher sensitivity and positive predictive value in evaluating lymph node metastasis of PTC than use of only one of them. Conclusion Overexpression of CD44v6 and EGFR indicates the PTC's biological feature of easy LNM and parallel use of CD44v6 and EGFR can act as a relatively good tumor metastatic marker of PTC.
