LIU Miao, SHEN Yan, FU Xiao-hong, WU Shu, HE Jie
Objective: To assess the value of virtual touch tissue imaging quantification(VTIQ) in different diameter TI-RADS 4 thyroid nodules on ultrasound. Methods: 191 patients with 195 pathologically proven benign(86) and malignant(109) thyroid nodules underwent TI-RADS and VTIQ examinations, and all the nodules were identified as TI-RADS 4． The thyroid nodules of TI-RADS 4 were divided into two groups according to diameter(≤10 mm and >10 mm)． Shear wave velocity(SWV) were measured with VTIQ. To assess the diagnostic value of TI-RADS, VTIQ and their combination in each group, the receiver operating characteristic(ROC) curves of TI-RADS, VTIQ and their combination were drawn in two groups. Areas under the curve(AUC) were compared between the two groups． Results: The sensitivity, specificity, positive predictive value, negative predictive value, accuracy and AUC of TI-RADS, VTIQ and their combination for the group(diameter≤10 mm) were 70.00%, 95.24%, 94.50%, 72.72%, 81.52%, 0.826; 82.00%, 78.57%, 82.00%, 78.57%, 80.43%, 0.803 and 96.00%, 76.19%, 82.76%, 94.12%, 86.96%, 0.861. In another group(diameter>10 mm), the sensitivity, specificity, positive predictive value, negative predictive value, accuracy and AUC were 67.80%, 90.91%, 90.91%, 67.80%, 77.67%, 0.794; 79.66%, 79.55%, 83.93%, 74.47%, 79.61%, 0.796 and 91.53%, 75.00%, 83.08%, 86.84%, 84.87%, 0.833. Three methods compared between the two groups have no statistically difference. Conclusion: It’s of high value for VTIQ to differentiate benign and malignant ones in different diameter TI-RADS 4 thyroid nodules. The sensitivity of the combination method was better than that single method. Between two groups, it’s better for the group which diameter≤10 mm in using VTIQ and their combination.

Objective: To evaluate the clinical significance of preoperative US features of papillary thyroid microcarcinoma(PTMC) predicting central compartment lymph node metastases(CCLNM). Methods: The sonographic features of 182 patients with pathologically confirmed PTMC in Hangzhou First People’s Hospital from March 2014 to October 2015 were retrospectively reviewed. The relationship between ultrasound characteristics of PTMC and CCLNM was analyzed by univariate analysis and logistic regression analysis. Results: The ipsilateral central lymph nodes from 220 sides were dissected in 182 cases of PTMC, of which 88 side of central lymph nodes were metastasis, so the rate of lymph node metastasis was 40%. Univariate analysis revealed that CCLNM was associated with certain preoperative US features, which included lesion location, tumor size, capsule invasion and microcalcification. Moreover, Logistic regression analysis only showed that the preoperative US features of lesion location, tumor size and capsule invasion were independent factors correlated with CCLNM. Conclusions: The lesion location, tumor size and capsule invasion determined by preoperative ultrasound in PTMC are positively correlated with CCLNM.

Objective: To estimate the relations between tumor’s longest diameter, area, volume and their reduction rate after neoadjuvant chemotherapy(NACT) and pathological response classification in patients of locally advanced breast cancer, and then investigate the application value of automated breast volume scanner(ABVS) in evaluating the curative effect of NACT. Methods: A prospective study was undertaken in patients undergoing NACT for locally advanced breast cancer in order to determine the ability of quantitative ABVS to assess the final pathologic response. Eighty-one patients were divided into two groups based on pathological response. Pathological response was assessed according to Miller & Payne grading system, of which grade 4 and 5 defined as major histological response(MHR), and grade 1 to 3 as non-major histological response(NMHR). Eighty-one cases with pathologically confirmed locally advanced breast cancer who had been performed four courses of NACT underwent preoperative breast ABVS three times during the NACT. The results are analyzed with T test(or Mann-Whitney U test). Concordance correlation coefficient(CCC) was used to evaluate the agreement among above methods． Receiver operating characteristic curve(R0C) analysis was applied to assess the predictive value of tumor size and the reduction rate． Results: Before, after the second and the fourth cycle of NACT, there were statistical differences in tumor’s longest diameters, areas and volumes among three measurements in MHR group(P<0．05), so does NMHR group(P<0．05)． There were also statistical difference in tumor’s longest diameters between MHR and NMHR(P<0．05), while no difference in tumor’s areas and volumes(P>0．05). The differences between first and second measurements after NACT showed significantly statistical difference(P<0．05)． The reduction rate in MHR group was higher. The same results of reduction rate were found in inter-group between first and second measurements(P<0．05). And the value of second measurement was higher, while the tendency was more obvious in MHR group. Base on reduction rate of their longest diameters, areas and volumes of two times, we take postoperative pathological response as golden standard to get the ROC curve and area under curve(AUC), the above indicators results of first measurement were as follows: 0.696, 0.693, 0.723, the second measurements results were 0.807, 0.824, 0.858. But there were no statistical significance between them. Conclusion: To measure the lesion’s longest diameters, areas and volumes of breast cancer patients with ABVS before and after NACT, we found their agreement are well. ABVS is valuable in evaluating the curative effect of neoadjuvant chemotherapy in patients with breast cancer. After NACT the assessment efficacy of the reduction rate of tumor’s longest diameter, area and volume had significantly predicted effect on estimating pathological reaction

AYIKELIMU Muhamaitihan1, DENG Jia-min1, WANG Yun-ling1, MA Jing-xu1, JIA Wen-xiao2
Objective: To investigate the role of apparent diffusion coefficient(ADC) value in the diagnosis of breast cancer and its association with tumor volume and hormonal receptors(estrogen receptor(ER), progesterone receptor(PR), and human epidermal growth factor(HER2)). Materials and Methods: Fifty-three patients with pathology-proven breast cancer and 31 with benign pathology were detected by diffusion weighted imaging(DWI) on 1.5T MR. ADC value and tumor size were measured respectively. Results: Mean ADC of malignant lesions was significantly lower((1.02±0.13)×10-3 mm2/s) compared to benign ((1.56±0.29)×10-3 mm2/s) lesions. A cutoff ADC value of 1.23×10-3 mm2/s(sensitivity 88.5%, specificity 85.1%, area under the curve 0.91) was obtained to differentiate malignant from benign diseases. Breast cancers with ER+, PR+, and triple-negative (TN) status showed a significantly larger tumor volume compared to ER+, PR+, and non-triple-negative (nTN) cancers, respectively. Furthermore, TN tumors showed a significantly higher ADC compared to ER+, PR+, and nTN cancers. Conclusion: ADC may increase the diagnostic specificity of DCE-MRI and be useful for evaluating prognosis of the tumor and guiding clinical therapy.
