Long-term survival and postoperative complications of pre-liver transplantation transarterial chemoembolisation in hepatocellular carcinoma: A systematic review and meta-analysis

ObjectivesThe aim of this meta-analysis was to conduct a contemporary systematic review of high quality non-randomised controlled trials to determine the effect of pre-liver transplantation (LT) transarterial chemoembolisation (TACE) on long-term survival and complications of hepatocellular carcinoma (HCC) patients.BackgroundTACE is used as a neoadjuvant therapy to mitigate waitlist drop-out for patients with HCC awaiting LT. Previous studies have conflicting conclusions on the effect of TACE on long-term survival and complications of HCC patients undergoing LT.MethodsCINAHL, Cochrane Controlled Register of Trials, Embase, PubMed, and Web of Science were systematically searched. Baseline characteristics included number of patients outside Milan criteria, tumour diameter, MELD score, and time on the waiting list. Primary outcomes included 3- and 5-year overall and disease-free survival. Secondary outcomes included tumour recurrence, 30-day postoperative mortality, and hepatic artery and biliary complications.ResultsTwenty-one high-quality NRCTs representing 8242 patients were included. Tumour diameter was significantly larger in TACE patients (3.49 cm vs 3.15 cm, P = 0.02) and time on the waiting list was significantly longer in TACE patients (4.87 months vs 3.46 months, P = 0.05), while MELD score was significantly higher in non-TACE patients (10.81 vs 12.35, P = 0.005). All primary and secondary outcomes displayed non-significant differences.ConclusionPatients treated with TACE had similar survival and postoperative outcomes to non-TACE patients, however, they had worse prognostic features compared to non-TACE patients. These findings strongly support the current US and European clinical practice guidelines that neoadjuvant TACE can be used for patients with longer expected waiting list times (specifically >6 months). Randomised controlled trials would be needed to increase the quality of evidence.     

Post-Closure Technique to Reduce Vascular Complications Related to Impella CP

BackgroundUse of percutaneous mechanical circulatory support has grown exponentially. Vascular complications remain a growing concern and best practices for device removal do not exist. We describe a novel post-closure technique for the next generation Impella CP removal and immediate hemostasis.MethodsThis study is a single center, retrospective, exploratory analysis of 11 consecutive patients receiving an Impella CP for either high-risk PCI or cardiogenic shock and then referred for post-closure compared to 20 patients receiving manual compression for Impella CP removal between 2017 and 2019.ResultsMean age range was 62.7–65.4 years and 50–65% male between groups. Average duration of Impella CP treatment ranged from 3.4 to 5.2 days. Patients referred for post-closure had significantly lower rates of all-cause adverse vascular events (0% versus 40%; n = 0/11 versus n = 8/20; p = 0.01). There was no significant difference in BARC 3 or greater bleeding, transfusion requirement, hospitalization duration or intensive care duration between removal strategies.ConclusionThe novel post-closure technique may significantly reduce vascular complications associated with device removal and may improve clinical outcomes for these critically ill patients.
