RESUMO
Objective To investigate the efficacy and safety of programmed death receptor-1 (PD-1) inhibitor combined with transarterial chemoembolization (TACE) and anti-angiogenic drug tyrosine kinase inhibitor (TKI) versus TACE combined with TKI in the treatment of advanced hepatocellular carcinoma (HCC) and related influencing factors for prognosis. Methods An analysis was performed for all patients who received TACE+TKI+PD-1 inhibitor and some patients who received TACE+TKI in The First Affiliated Hospital of Air Force Medical University from June 2018 to July 2021. Related clinical data were collected, and propensity score matching (PSM) was used to balance the baseline characteristics between groups. The chi-square test was used for comparison of categorical data between two groups; the Wilcoxon rank-sum test was used for comparison of the number of TACE procedures between two groups; the Kaplan-Meier method was used to analyze overall survival (OS), and univariate and multivariate Cox regression models were used to analyze the influencing factors for prognosis. Results A total of 181 patients with advanced HCC were screened out, among whom 50 patients were treated with TACE+TKI+PD-1 inhibitor; after PSM, 40 patients treated with TACE+TKI+PD-1 inhibitor were enrolled as observation group and 40 patients treated with TACE+TKI were enrolled as control group. At the end of follow-up, the median follow-up time was 28.6 (95% confidence interval [ CI ]: 22.1-35.1) months, and the median OS was 15.9 (95% CI : 7.5-24.2) months in the observation group and 11.2 (95% CI : 5.0-17.5) months in the control group. The Cox regression analysis showed that the application of PD-1 inhibitor (hazard ratio [ HR ]=0.42, 95% CI : 0.23-0.80, P =0.008), the number of TACE procedures ( HR =0.67, 95% CI : 0.46-0.99, P =0.043), Child-Pugh class ( HR =2.40, 95% CI : 1.15-5.00, P =0.019), and vascular invasion ( HR =3.42, 95% CI : 1.11-9.42, P =0.031) were independent influencing factors for prognosis. The incidence rate of grade > 2 adverse events was 40% for both the observation group and the control group, and there was no significant difference between the two groups ( P =0.818). Conclusion Compared with TACE+TKI, TACE+TKI+PD-1 inhibitor can significantly prolong the OS of patients in advanced HCC, with relatively controllable adverse events.
RESUMO
The relationship of intestinal microbiota with multifarious diseases becomes a hot spot of research in recent years,and accumulated evidence indicates that the intestinal microbiota also plays a key role in chronic liver diseases.Due to special anatomical location between the liver and the intestinal tract, the conditions of liver and intestinal microbiota are extensively interacted.This article reviews the current research progress on the relationship between intestinal microbiota and chronic liver diseases.
RESUMO
Objective To investigate the clinical applications of sandwich technique according to area calculation in endovascular aneurysm repair of patients with aorta and iliac artery lesions.Methods Six patients with aortoiliac artery disease confirmed by CT were treated using sandwich technique according to area calculation.The diameter of the main stent and two branches stents were chosen according to the area calculation.Technical success rate,patency of the stent graft and complications were observed.Results Technical success rate was 100％ (6/6),and no complications occurred in all the 6 patients.The clinical symptoms were significantly improved.Gutter endoleak was found in 1 patient 2 months after the procedure,and was managed by coil embolization successfully.No endoleak occurred in other patients during follow-up of 6-31 months.Conclusion For patients with special anatomy of aorta and iliac artery lesions,the application of area calculation in the sandwich technique provides a feasible approach in choosing the matching size of the main body stent and two side branches stents.
