[Abstract]:Objective: to detect the characteristics of liver tissue elasticity in patients with breast cancer TAC combined with chemotherapy by ultrasonic tissue diffusion quantitative analysis, and to provide an effective ultrasonic quantitative method for early assessment of liver injury. Methods: selected outpatient medical examiners and pathologically in Zhongshan Hospital Affiliated to Dalian University, September 2015, ~2016 years, in December. In the case of breast cancer, 6 cycles of TAC combined chemotherapy were required. Among them, 38 cases in the control group and 35 cases in the chemotherapy group. In the chemotherapy group, 24 cases were treated with neoadjuvant chemotherapy and 11 patients with adjuvant chemotherapy after operation, 6 cycles of continuous chemotherapy and a cycle for 21 days. The data collection period in the chemotherapy group was respectively before chemotherapy and second and fourth cycles, respectively. 1-2 days after the end of the 6 period. Main contents: 1. routine liver ultrasound examination; 2. ultrasound tissue diffusion quantitative analysis, including liver fibrosis index, LFI, area ratio,%AREA, strain mean (mean, MEAN), standard deviation (standard deviation, SD), complexity, contrast, contrast Ntrast, CONT), kurtosis (KURT), skewness, SKEW, entropy, ENT, inverse difference moment, IDM, consistency and correlation, including glutamate aminotransferase, aspartate aminotransferase Artate aminotransferase, AST), alkaline phosphatase (alkaline phosphatase, ALP), total bilirubin (total bilirubin, TB) and conjugated bilirubin (conjugated bilirubin, CB). Compared with the chemotherapy group before chemotherapy and the control group, and the comparison between the different chemotherapy cycles of the chemotherapy group and the elastic parameters reflecting the hardness of the liver. The correlation analysis of LFI,%AREA and MEAN with the biochemical indexes of liver function, and further drawing the ROC curve after the second cycle of chemotherapy and the end of the 4 cycle respectively, calculated the area under the curve, the critical value, the sensitivity and the specificity. Results: 1. routine ultrasound examination: 35 cases of chemotherapy group were normal before the chemotherapy, compared with the chemotherapy before chemotherapy, chemotherapy After the second cycle, 3 cases (8.57%) had abnormal echo enhancement in the liver (P0.05); after the end of the fourth cycle of chemotherapy, 18 cases (51.43%) had abnormal echo enhancement in the liver (P0.05); after the end of the chemotherapy sixth period, the abnormal expression of echo enhancement in the liver of 29 patients (82.86%) (P0.05).2. tissue diffusion quantitative analysis: Before chemotherapy before chemotherapy,%AREA, SD and LFI increased (P0.05), and MEAN decreased (P0.05),%AREA, SD, CONT and LFI increased (P0.05) after chemotherapy second cycle after chemotherapy second cycle. P, CONT and LFI increased (P0.05). Compared with chemotherapy for different weeks, after the end of chemotherapy fourth cycle and after the end of chemotherapy second cycle, MEAN decreased (P0.05),%AREA, CONT, COMP and LFI increased (P0.05). After the end of the cycle, after the end of the fourth cycle of chemotherapy, MEAN decreased (P0.05),%AREA, SD and LFI increased (P0.05).3. liver function biochemical indexes: before chemotherapy group, the difference of each index was not statistically significant compared with the control group (P0.05). After the chemotherapy before the chemotherapy, ALT, AST showed an upward trend (P0.05), but AST is still positive. ALT was at the normal limit; ALT, AST and ALP increased after fourth cycles of chemotherapy (P0.05); ALT, AST, ALP, TB and CB increased after the end of the sixth cycle of chemotherapy (P0.05). After the end of second cycles, ALT, AST, ALP, TB and CB were all increased (P0.05); after the end of the sixth cycle of chemotherapy, after the end of the fourth cycle of chemotherapy, ALT, AST, ALP, TB and CB were all increased. =0.011) showed a negative correlation.5.ROC curve showing LFI, the area of%AREA and MEAN was 0.752,0.655 and 0.623 in second cycles of chemotherapy, respectively, 0.921,0.795 and 0.804 in the fourth cycles of chemotherapy, and the critical value of LFI,%AREA and MEAN was 1.94 in the second cycle of chemotherapy (sensitivity 77.1%, specificity, specificity). Degree 63.2%), 17.33 (sensitivity 85.7%, specificity 42.1%) and 112.81 (sensitivity 88.6%, specificity 36.8%), 1.99 in the fourth cycle of chemotherapy (sensitivity 97.1%, specificity 73.7%), 21.36 (sensitivity 71.4%, specificity, specificity). Conclusion: ultrasound tissue diffusion quantitative analysis technique can be used for quantitative detection of breast cancer The elastic characteristics of liver tissue in patients with chemotherapy. The elastic parameters LFI,%AREA and MEAN are more sensitive, and the sensitivity and specificity of LFI are better. It is expected to be a valuable indicator for quantitative ultrasound assessment of early liver injury in patients with TAC combined with chemotherapy.
