摘要
[目的]评价CK19,P53,P63,EMA在鉴别甲状腺良恶性(乳头状癌)病变中的临床应用价值;了解甲状腺乳头状癌P170蛋白表达的意义。[方法]通过免疫组织化学方法,检测CK19,P53,P63,EMA,及P170蛋白在38例甲状腺乳头状癌和38例甲状腺良性病变中的表达。[结果]CK19、P53、P63、EMA在甲状腺乳头状癌和良性病变中的阳性率分别为92.1%(35/38)和2.6%(1/38)(P<0.005),89.5%(34/38)和18.4%(7/38)(P<0.005),23.7%(9/38)和10.5%(4/38)(P>0.1),34.2%(13/38)和50%(19/38)(P>0.1)。甲状腺乳头状癌中P170表达阳性率为57.9%(22/38)。[结论](1)CK19和P53是甲状腺乳头状癌病理诊断中非常有价值的辅助诊断指标。(2)甲状腺乳头状癌中P170表达的阳性率与CK19的阳性程度密切相关。
[ Objective] To estimate the clinical value of CK19 ,P53 ,P63 ,EMA on distinguishing benign and malignant thyroid disease especially for PTC. To know more about the meaning of P170' s expression in PTC. [ Methods] By immunohistochemical method called Elivision, CK19,P53 ,P63 ,EMA,P170 are examined respectively in 38 PTC patients and in 38 thyroid benign disease patients. [ Re- suits] CK19,P53 ,P63 ,EMA expression rates in PTC and benign disease of thyroid were 92.1% (35/38) and 2.6% (P 〈0.005) ; 89.5 % ( 34/38 ) and 18.4% ( 7/38 ) ( P 〈 0. 005 ) ; 23.7 % ( 9/38 ) and 10.5 % ( 4/38 ) ( P 〉 0.1 ) ; 34.2 % ( 13/38 ) and 50% ( 19/ 38 ) (P 〉0.1 ) ;In 22 cases of the PTC group ,the positive rate of P170 is 57.9%. [ Conclusions] ( 1 ) CK19 and P53 are valuable assistant diagnostic points for PTC pathological diagnosis. (2) The positive rate of P170 expression is high in PTC and closely related to CK19.
