ABSTRACT
Objective To compare effect between thyroid imaging reporting and data system (TI-RADS) and the Bethesda system for reporting thyroid cytopathology (TBSRTC) in the qualitative diagnosis of thyroid nodule. Methods The clinical data of 665 patients with thyroid nodule (1 598 nodules) from April 2013 to October 2016 were retrospectively analyzed. TBSRTC and TI-RADS were used for qualitative diagnosis of thyroid nodule before operation. Pathological diagnosis was performed after the operation. The diagnostic effect of TI-RADS and TBSRTC were assessed, and the factors leading to the diagnostic errors were analyzed. Results Of 1 598 thyroid nodules, the pathological diagnosis showed that benign nodules were in 202, and malignant thyroid nodules were in 1 396. The diagnostic sensitivity and 85.64%(173/202) vs. 74.75%(151/202) and specificity of malignant nodules by TBSRTC were significantly higher than that by TI-RADS 91.76% (1 281/1 396) vs. 87.11% (1 216/1 396), and there was statistical difference (P<0.01). The diagnosis positive rate of malignant nodules with diameter<1 cm by TBSRTC was significantly higher than that by TI-RADS 77.63% (59/76) vs. 47.37% (36/76), and there was statistical difference (P<0.01); there was no statistical difference in diagnosis positive rate of malignant nodules with diameter ≥ 1 cm between 2 methods (P>0.05). Univariate analysis result showed that the diameter of thyroid nodules in patients with TI-RADS false negative was significantly smaller than that in patients with benign thyroid nodules (1.01 ± 0.48) cm vs. (1.51 ± 0.45) cm, the incidence of malignant thyroid nodules combined with other thyroid diseases was significantly higher than that in patients with benign thyroid nodules 41.18% (21/51) vs. 11.32% (158/1 396), and there were statistical differences (P<0.05); the rate of thyroid dysfunction in patients with TBSRTC false positive was significantly higher than that in patients with malignant thyroid nodules 18.26% (21/115) vs. 6.93% (14/202), and there was statistical difference (P<0.05). Conclusions The qualitative diagnosis of thyroid nodule requires the cross-reference of TI-RADS and TBSRTC, and the combination of other clinical indicators of patients can improve the detection rate of malignant thyroid nodules.
