ObjectiveTo explore the diagnostic value of sonography in thyroid imaging reporting and data system (TI-RADS) for thyroid nodules. MethodsA total of 292 patients (423 nodules) underwent thyroid examination with high frequency ultrasound. The results were retrospectively compared with histopathological diagnosis and TI-RADS lexicon. ResultsThe category 1-5 of 423 thyroid nodules were evaluated by using TI-RADS, and it’s frequency of being malignancy rate was 0(0/129), 6.3%(11/176), 33.3%(10/30), 86.8%(46/53), and 100% (35/35), respectively. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for benign thyroid nodule of ultrasound in TI-RADS was 96.3%（309/321）, 83.3%（85/102）, 93.1%（394/423）, 94.8%（309/326）, and 87.6%（85/97）, respectively. Positive likelihood ratio, negative likelihood ratio, and Youden’ index was 5.77, 0.04, and 79.6%, respectively. The benign and malignancy nodule of TI-RADS category were statistically difference in shape, margin, echogenicity, echotexture, composition, and calcification inside the nodule (Plt;0.001). ConclusionsTI-RADS lexicon has an important guiding value for clinical diagnosis and treatment in ultrasound examination of thyroid nodule.
Objective To compare differences of characteristics of ultrasonic elasticity imaging for benign and malignant small thyroid nodules with or without Hashimoto thyroiditis (HT). Methods The thyroid nodules with ≤1 cm size and the category 4A, 4B, 4C, and 5 of Thyroid Imaging Reporting and Data System (TI-RADS) were included into this study, and a further examination of real-time elastography was performed. The final diagnosis was relied on the pathological diagnosis. The elasticity score and strain ratio (SR) were recorded and compared between these two groups, respectively. Results Of the 424 nodules, 103 nodules were accompanied with HT (thyroid nodule with HT group), 321 nodules were not accompanied with HT (thyroid nodule without HT group). In the thyroid nodule with HT group, the area under the receiver operator characteristic (ROC) curve (AUCs) of the elasticity score and the SR was 0.685 and 0.676, respectively; the optimal cut offs of the elasticity score and the SR was 3 points and 2.45 respectively, their corresponding sensitivity, specificity, and accuracy was 75.7%, 57.6%, 68.0% and 75.7%, 60.6%, 67.6%, respectively. In the thyroid nodule without HT group, the AUCs of the elasticity score and the SR was 0.692 and 0.692, respectively; the optimal cut offs of the elasticity score and the SR was 4 points and 2.84, respectively; their corresponding sensitivity, specificity, and accuracy was 57.5%, 74.2%, 69.2% and 76.1%, 59.7%, 67.7%, respectively. Conclusions Elastography is helpful in differential diagnosis of benign and malignant small thyroid nodules. While, standards of elasticity score and SR value in differential diagnosis are different between benign and malignant small thyroid nodules with HT and without HT, elasticity score and SR ratio decrease in benign and malignant small thyroid nodules with HT.
ObjectiveTo evaluate the value of preoperative risk assessment of papillary thyroid carcinoma with ultrasound for clinic diagnosis and treatment.MethodsThe data of 400 patients with papillary thyroid carcinoma received operative treatment in 2017 were retrospectively analyzed. Recorded and analyzed the ultrasonic risk assessment and postoperative grading of clinic risk assessment, to evaluate coherence and correlation between them.ResultsThere were 400 lesions with an average size of (12.8±8.5) mm. Among 400 lesions, diameter of 214 lesions less than 10 mm, diameter of 178 lesions were between 10 mm and 40 mm, and diameter of 8 lesions were larger than 40 mm. A total of 242 cases had lymph node metastasis and 309 cases had capsule invasion. Clinical and ultrasoud risk assessment was performed on 400 lesions. There were 224 lesions with low risk of clinical risk stratification vs. 111 lesions with low ultrasonic risk, 148 lesions with intermediate risk of clinical risk stratification vs. 270 lesions with intermediate ultrasonic risk, and 28 lesions with high risk of clinical risk stratification vs. 19 lesions with high ultrasonic risk. The consistency of postoperative recurrence risk stratification and preoperative ultrasound recurrence risk stratification was moderate (κ=0.414, P<0.01). In addition, the consistency between ultrasound examination and clinical lymph node metastasis was poor (κ=0.291, P<0.05), and the consistency of invasion of the capsule was moderate (κ=0.402, P<0.05).ConclusionPre- operative evaluation of recurrence risk grading before thyroid ultrasound, focusing on individualized preoperative assessment, the assessment is more detailed and detailed, and is helpful for follow-up treatment and early screening for recurrence risk.

Methods Between January 2005 and September 2010, 127 women with 137 non-palpable breast lesions underwent surgical excision at West China Hospital. Palpation results for all the lesions were negative. Wire localization guided by ultrasound was performed before operation and biopsy. Related imaging studies and medical records were reviewed retrospectively. Results Histological findings showed there were 101 benign lesions (73.7%), 27 high-risk lesions (19.7%), and 9 carcinomas (6.6%). Among the 9 carcinomas, 3 were ductal carcinoma in situ, and 6 were infiltrating carcinoma (with their size ranged from 11 to 19 mm averaging at 14.2 mm). The time of performing ultrasound-guided wire localization was from 3 to 15 minutes averaging at 6. No complications like hematoma, wire fragments, and wire breakage occurred in all cases. The surgical excision time ranged from 20 to 40 minutes averaging at 30. Conclusions Ultrasound-guided wire localization can be performed quickly and safely for the cases of non-palpable breast lesions. It is useful in assisting surgical excision and biopsy.
ObjectiveTo explore the value of active surveillance (AS) with ultrasound for papillary thyroid microcarcinoma (PTMC) tumor growth.MethodsA retrospective collection of 196 patients who underwent ultrasound-guided fine-needle aspiration biopsy at West China Hospital of Sichuan University from January 2014 to December 2018 were pathologically diagnosed as PTMC, and no cervical lymph node metastasis was found on ultrasound, and AS was performed. According to the change of the maximum diameter of the nodule, the patients were divided into the maximum diameter increase group, the maximum diameter stable group and the maximum diameter reduction group. According to the nodule volume change, the patients were divided into the volume increase group, the volume stable group and the volume reduction group. The differences in the patients’ gender, age, with Hashimoto’s thyroiditis, follow-up time, tumor size, boundary, shape, echo, aspect ratio, calcifications, multifocality, bilateral involvement, other nodule, surrounding tissues and cervical lymph nodes among the different groups were analyzed in order to clarify the related factors of tumor growth.ResultsOne hundred and ninety-six patients had ultrasound AS time ranging from 6 to 79 months with the median (quartile) time were 16.0 (10.0, 30.0) months. One hundred and seventeen patients (59.7%) were in AS for 6 to 63 months with the median (quartile) time were 13.0. (8.0, 22.0), surgical treatments were performed after termination of AS. Forty-five patients (23.0%) continued to perform AS, 34 patients (17.3%) did not continue to perform AS in West China Hospital of Sichuan University. There was no significant reduction in the maximum diameter and volume of the nodules in all cases. Among them, 9 cases (4.6%) had an increase in the maximum diameter of the nodules, and 187 cases (95.4%) had a stable maximum diameter. Forty cases (20.4%) had an increase in the volume of the nodules, and 156 cases (79.6%) had a stable volume of the nodules. Comparison of the maximum diameter change of nodules between the two groups, there was a significant difference in the age of patients (P<0.05). Comparison of the maximum volume change between the two groups, there were significant differences in age, follow-up time and initial nodule volume (P<0.05). Logistic regression analysis showed that younger age was an independent risk factor for PTMC nodule growth [OR＝0.638, 95%CI (0.601, 0.675), P＝0.015].ConclusionsYounger age is a risk factor for PTMC tumor growth. We should adopt a more active monitoring program for younger patients. The increase of PTMC tumor volume can be more easily monitored than the increase of its maximum diameter, so it can be used as an indicator to predict nodule growth at an earlier stage in AS.
Objective To explore the risk factors the central cervical lymph node micrometastasis of papillary thyroid microcarcinoma (PTMC). Methods PTMC patients who underwent surgical operations in West China Hospital, Sichuan University between January 2014 and December 2018 were retrospectively enrolled. The patient did not find lymph node metastasis in the central cervical area by preoperative ultrasound. During the operation, the central cervical lymph node of the affected side was dissected or lymph node dissection in the central area of the affected side of the neck plus the lateral area of the neck. With postoperative pathology as the gold standard, patients were divided into central cervical lymph node micrometastasis group (micrometastasis group) and central cervical lymph node non-metastasis group (non-metastasis group). The differences of clinical features and ultrasonic signs between the two groups were analyzed. Results A total of 507 patients were included, including 223 (44.0%) in the micrometastasis group and 284(56.0%) in the non-metastasis group. The results of univariate analysis showed that compared with the non-metastasis group, the patients in the micrometastasis group were younger, the tumor size were higher, the proportion of male, multifocality, bilateral involvement and thyroid capsular invasion were higher. The results of multiple logistic regression analysis showed that lower age [odds radio (OR)=0.967, 95% confidence interval (CI)(0.949, 0.985), P<0.001], male [OR=2.357, 95%CI (1.503, 3.694), P<0.001)], a larger maximum diameter of PTMC [OR=1.232, 95%CI (1.100, 1.379), P<0.001], a larger nodule volume of PTMC [OR=1.031, 95%CI (1.008, 1.114), P=0.032], multifocal lesion [OR=2.309, 95%CI (1.167, 4.570), P=0.016] and invasion of the thyroid capsule [OR=1.520, 95%CI (1.010, 2.286), P=0.045] were independent risk factors for central cervical lymph node micrometastasis. Conclusions The patient’s male, young age, PTMC nodule with large maximum diameter and large volume, multifocal, and invasion of the thyroid membrane are risk factors for the central cervical lymph node micrometastasis of PMTC patients. These clinical and ultrasound signs can provide a theoretical basis for doctors’ clinical management decisions.
Objective To discuss the nursing measures for thyroid nodule patients who undergo core-needle biopsy (CNB) guided by ultrasound. Methods We retrospectively analyzed the experiences and main points of nursing for 1 900 thyroid nodule patients who underwent CNB guided by ultrasound between June 2010 and May 2014. Results All the 1 900 patients underwent CNB successfully. The nursing time was between 5 and 15 minutes, averaging (8.0±3.7) minutes. Complications included hematoma in 25 patients (1.3%) and needle syncope reaction in 30 patients (1.6%), which were cured through symptomatic treatment. No complications such as nerve injury, anesthesia accident or death occurred. No medical disputes happened due to specimen errors or loss. The success rate of specimen collection was 98.4% (1 870/1 900), and the diagnostic accuracy was 95.3% (1 812/1 900). Conclusions Ultrasonography-guided CNB is a safe and reliable operation with a high success rate, high diagnosis accuracy and few complications. Being familiar with the process of nursing cooperation and correct disposal and transfer of biopsy specimens are crucial for successful CNB in patients with thyroid nodules.
