摘要
目的 探讨超声引导下细针穿刺细胞学(ultrasound-guided fine-needle aspiration cytology,US-FNAC)联合降钙素(calcitonin,CT)、嗜铬素A(chromogranin A,CgA)、甲状腺球蛋白(thyroglobulin,Tg)诊断甲状腺髓样癌(medullary thyroid cancer,MTC)的应用价值.方法 对7例US-FNAC诊断且术后组织病理学确诊的MTC临床资料和超声特点、细胞病理学特征进行综合分析.细针穿刺标本采用常规涂片1～2张自然风干后刘氏染色液快速染色,现场进行细胞病理学评判,确保取得满意的细胞量,同时将剩余标本注入液基细胞保存液中保存,采用液基薄层制片,HE染色及CT、CgA和Tg免疫组织化学染色.结果 7例MTC细胞均中等量到大量,均有散在突出的大细胞、双核细胞、浆样细胞或核偏位不规则细胞;6 例伴梭形细胞,细胞病理学表现与MTC细胞学诊断标准基本相符,CT、CgA胞质均弥漫强阳性表达,Tg阴性,细胞病理学诊断为MTC.结论 US-FNAC 技术可提高甲状腺结节细针穿刺标本满意度,结合液基薄层制片与CT、CgA免疫组织化学染色可提高MTC术前诊断准确性,对 MTC治疗具有重大的临床意义.
Abstract
Objective To explore the application value of trasound-guided fine-needle aspiration cytology(US-FNAC)com-bined with calcitonin(CT),chromogranin A(CgA),and thyroglobulin(Tg)in the diagnosis of medullary thyroid carcinoma(MTC).Methods The clinical data,ultrasonic characteristics and cytopathological characteristics of seven cases of MTC diagnosed by US-FNAC and confirmed by histopathology after operation were comprehensively analyzed.After 1-2 smears of fine needle aspiration specimens were made,the smears were dried naturally,and then quickly stained with Liu's staining solution.Rapid on-site evalua-tion(ROSE)was carried out by cytophology to ensure satisfactory cell volume.Meanwhile,the remaining samples were injected into liquid-based cell preservation solution,liquid-based thin layers were prepered,HE staining and immunohistochemical staining of CT,CgA and Tg were performed.Results The number of cells in 7 cases of MTC was moderate to large,there were all scattered in prom-inent large,binuclear,plasmic-like,or nuclear-biased irregular cells;six with spindle cells,and the microscopic characteristics of the cells were basically consistent with the cytological diagnostic criteria of MTC.CT and CgA showed diffuse strong positive expression in cytoplasm,but Tg was negative,and the cytopathological diagnosis was MTC.Conclusion US-FNAC can improve the sample satis-faction of fine needle aspiration of thyroid nodules.Combined with fluid based thin layer preparation and CT,CgA immunocytochemi-cal staining,the accuracy of preoperative diagnosis of MTC can be improved,which has great clinical significance for the treatment of MTC.
