探讨不同病理类型甲状腺癌的TI－RADS分类应用价值。

回顾性分析2015年7月至2018年7月的120例甲状腺癌患者资料，患者均经超声诊断及手术病理证实为甲状腺癌患者。结节共计被检出200个，其中恶性结节为108个。利用统计学软件SPSS22.0对数据进行分析，甲状腺癌的病理类型诊断、TI－RADS分类与不同病理类型诊断结果对比采取χ²(%); P<0.05差异有统计学意义。

病理结果显示，甲状腺乳头状癌108例，甲状腺滤泡癌4例，甲状腺髓样癌6例，甲状腺嗜酸性细胞肿瘤2例；应用超声TI－RADS分类的诊断效能检验显示：阳性似然比为3.35<10，而阴性似然比0.13>0.1；阳性预测值达91.82%，而阴性预测值达75.61%，以上表明超声TI－RADS分类对患者病理类型的诊断效能较高。

TIRADS分类对于乳头状癌、结甲合并乳头状癌的诊断准确性较高，而对于髓样癌、滤泡癌、慢甲炎分类却不准确，临床应以鉴别诊断。

To investigate the application value of TI-RADS classification for different pathological types of thyroid carcinoma.

The data of 120 patients with thyroid cancer from July 2015 to July 2018 were retrospectively analyzed. Thyroid cancer were confirmed in all patientsby ultrasonography and pathology. A total of 200 nodules were detected, including 108 malignant nodules. Statistical software SPSS22.0 was used to analyze. The results of pathological diagnosis, TI-RADS classification and different pathological types of thyroid cancer were compared by χ²(%); P<0.05 had significant difference.

Pathological results showed that 108 cases of papillary thyroid cancer, 4 cases of follicular thyroid cancer, 6 cases of medullary thyroid cancer and 2 cases of eosinophilic thyroid tumors. The diagnostic efficacy of TI-RADS classification showed that the positive likelihood ratio was 3.35 < 10, while the negative likelihood ratio was 0.13 > 0.1; the positive predictive value was 91.82%, while the negative predictive value was 75.61%. These results indicated that TI-RADS classification was effective for patients. The diagnostic efficiency of pathological type is high.

The TIRADS classification is more accurate in the diagnosis of papillary carcinoma, nodular goiter combined with papillary carcinoma, and inaccurate in the classification of medullary carcinoma, follicular carcinoma, and chronic thyroiditis. Using TI-RADS to classify thyroid pathological types can effectively improve the diagnostic accuracy of thyroid nodules, and clinically related fields can be widely promoted and applied.
