CD10表达在甲状腺滤泡性癌和滤泡型乳头状癌诊断中的作用

目的研究CD10表达在甲状腺滤泡性癌和滤泡型乳头状癌诊断中的作用。方法收集70例甲状腺良、恶性病变组织，其中包括15例滤泡性腺瘤、15例腺瘤性甲状腺肿、30例乳头状癌（包括9例滤泡型乳头状癌）和10例滤泡性癌，采用免疫组织化学方法检测CD10在上述组织中的表达。结果9例滤泡型乳头状癌中，7例表达CD10（77．8％），10例滤泡性癌中8例表达CD10（80．0％）；CD10在非滤泡型乳头状癌、滤泡性腺瘤、腺瘤性甲状腺肿和正常甲状腺组织中均不表达。结论对CD10表达的检测有助于对甲状腺滤泡性癌和滤泡型乳头状癌的诊断。

Role of CD10 Expression in Differential Diagnosis of Thyroid Follicular Carcinoma and Follicular Variant of Papillary Carcinoma

Objective To investigate the role of expression in the differential diagnosis of thyroid follicular carcinoma and follicular variant of papillary carcinoma. Methods Seventy cases of thyroid lesions (including 15 cases of follicular adenomas, 15 cases of adinomatous goiters, 30 cases of papillary carcinomas and 10 cases of follicular carcinomas) were collected, and CD10 expression was detected by means of immunohistochemistry in above thyroid lesions. Results Seven of 9 cases of follicular variant of papillary carcinoma were CD10 positive (77.8), and 8 of 10 cases of follicular carcinoma were CD10 positive (80.0). However, CD10 was negative in all cases of non-follicular variant of papillary carcinoma, follicular adenoma, adinomatous goiter and normal thyroid tissue. Conclusion The detection of CD10 expression is useful to the differential diagnosis of thyroid follicular carcinoma and follicular variant of papillary carcinoma.
