Objective To evaluate the clinical significance of CT + MRI scans in diagnosis of primary liver cancer and prognosis evaluation after interventional therapy. Methods A total of 150 cases of patients with primary liver cancer admitted to our hospital from January 2019 to January 2021 were selected. They all received interventional treatment, and were examined by CT and MRI. The results of pathological examination were taken as the gold standard in this study to compare the diagnostic efficacy of CT, MRI and CT+MRI.Kappa value was used to compare the consistency of CT, MRI, CT+MRI scans with gold standard, and compared the detection rate of lesions after CT, MRI and CT+MRI interventional surgery. Results The diagnostic accuracy (98.67%), specificity (75.00%) and sensitivity (99.32%) of CT + MRI scans were higher than those of CT (86.00%, 25.00%, 87.67%) and MRI scans (90.67%, 91.78%, 50.00%),P<0.05 (which differences were statistically significant). The consistency of CT + MRI scans with gold standard was good (kappa value was 0.779), but the consistency of CT/MRI scans with gold standard were not satisfying (kappa value were 0.527, 0.596). The total detection rate of lesions after CT + MRI interventional surgery (12.00%) was higher than that of CT (2.00%) and MRI (4.00%, which P<0.05). Conclusion CT + MRI scans can improve the detection rate of lesions in patients with primary liver cancer after interventional therapy, and make up for the deficiency of only CT or MRI scans.

Objective To investigate the thermal ablation effect of microbubble ultrasound cavitation combined with microwave ablation on rabbit VX2 tumors. Methods Twenty-four rabbits with liver transplantation tumors were randomly divided into four groups: blank control group, ultrasound-only cavitation treatment group, microwave-only ablation treatment group, and ultrasound-cavitation combined with microwave ablation treatment group. Enhanced ultrasound was used to show the size, shape and contour of the tumor before and after treatment in each group, and the local temperature of the treatment area was detected by a temperature needle. Results The blood flow perfusion defect was the most severe in the combined treatment group. The defect volume of the microwave ablation group and the combined treatment group were 1.53±0.20 and 1.68±0.43 (P=0.117). The temperature reached the plateau time in the microwave ablation group and the combined treatment group. It was (21.7±5.0)s and (10.3±5.0)s (P<0.01), and the highest temperature (℃) was 100.9±5.0 and 134.1±6.0 (P<0.01). Conclusion MWA combined with MEUS for liver cancer can sharply increase the local temperature in the treatment area to the peak temperature, which is expected to improve the treatment effect of liver cancer.

Objective To analyze the risk factors of advanced triple-negative breast cancer (TNBC) and establish an effective prognostic nomogram. Methods Screening patients with advanced TNBC by searching the SEER (surveillance, epidemiology, and end results) database, using univariate and multivariate analysis to determine the independent prognostic factors of advanced TNBC, and constructing a nomogram based on it. Results A total of 4 687 patients with advanced TNBC were included. Compared with other types of breast cancer over the same period, TNBC had the worst prognosis. Univariate analysis found that age, gender, stage, surgery, chemotherapy, radiotherapy, and metastasis were associated with a better prognosis (P<0.05). Multivariate analysis found that age, gender, race, stage, surgery, chemotherapy, radiotherapy, and metastasis of the organs were independent factors affecting the prognosis of patients (P<0.05), and constructed a nomogram with a C-index of 0.75 ( 95% CI, 0.71～0.79). The calibration chart showed the best agreement between the predicted overall survival (OS) and the observed OS. Conclusion We analyzed the clinical features of advanced TNBC, provided some prognostic factors for the OS of TNBC patients, and developed a nomogram based on these prognostic factors to help clinicians manage risk and choose long-term survival strategies for TNBC patients.
