目的 评价甲状腺肿瘤术前各种诊断方法的临床意义。方法 根据手术标本组织病理学诊断结果将36名单发性实质性甲状腺结节的患者分为良性肿瘤组 (A组 ,16名 )、恶性肿瘤组 (B组 ,2 0名 ) ,探讨其术前所行B型超声波 (B超 )、99mTc同位素扫描、B超引导细针穿刺细胞学诊断 ,以及测定血清甲状腺免疫球蛋白 (Tg)等检查的临床意义。结果 B超显像中 ,结节内部回声不均匀 ,或伴有细小钙化灶显像类型在恶性肿瘤中明显较多出现 (P <0 .0 5 )。B超引导细针穿刺细胞学诊断的正确率为 77.8% (P <0 .0 1) ,具有一定的临床意义。两组的血清Tg水平、99mTc同位素扫描结果均无显著差异。结论 B超 (结节内部回声 ,伴有细小钙化灶显像 )、B超引导细针穿刺细胞学检查为两种较有效的检查手段。
Objective To evaluate the clinical significance of preoperative diagnostic methods for thyroid tumors. Methods According to histopathological diagnosis results of surgical specimens, 36 patients with essential thyroid nodules were divided into benign tumor group (A group, 16 patients) and malignant tumor group (B group, 20 patients). The clinical significance of B-ultrasound (B-ultrasound), 99mTc isotope scanning, B-guided fine-needle aspiration cytology diagnosis, and determination of serum thyroglobulin immunoglobulin (Tg) were examined. RESULTS: In the B-mode ultrasound imaging, the echo within the nodule was uneven, or the type of the small calcified lesions appeared more frequently in the malignant tumor (P < 0.05). The accuracy of B-guided fine needle aspiration cytology diagnosis was 77.8% (P < 0.01), which had certain clinical significance. There was no significant difference in serum Tg levels and 99mTc isotope scans between the two groups. Conclusion B-ultrasonography (nodular internal echo with small calcification imaging) and B-guided fine-needle aspiration cytology are two effective methods.
