Transjugular Intrahepatic Portosystemic Shunt Creation for the Prevention of Gastric Variceal Rebleeding in Patients with Hepatocellular Carcinoma: A Multicenter Retrospective Study

Outcomes and Prognostic Factors in Cirrhotic Patients with Acute Variceal Bleeding and Hepatocellular Carcinoma: A Nested Case-Control Study

Purpose

The treatment outcomes and risk factors for the prognosis of acute variceal bleeding (AVB) in hepatocellular carcinoma (HCC) patients remain unclear. Hence, we assessed the clinical outcomes and prognostic factors of these patients.

Methods

This study retrospectively enrolled 1532 AVB patients with cirrhosis from January 2016 to December 2022. Of these patients, 310 had HCC, and after 1:1 individual matching, 306 of them were matched with 306 patients without HCC. Six-week mortality, one-year mortality, and five-day treatment failure were recorded.

Results

In the matched-pair analysis, patients with HCC had a higher rate of 6-week and 1-year mortality than those without HCC (6-week: 24.5% vs 7.8%, P < 0.001; 1-year: 45.9% vs 16.2%, P < 0.001). The rate of 5-day treatment failure was similar between the two groups (21.1% vs 16.7%, P = 0.213). Among AVB patients with HCC, the multivariate analysis revealed that the Child-Pugh score (HR, 1.239, 95% CI, 1.121-1.370; P < 0.001) and Barcelona Clinic Liver Cancer (BCLC) stage (C-D vs 0-B) (HR, 14.409; 95% CI, 5.758-36.055; P < 0.001) were independently associated with 6-week mortality. Moreover, the rate of 6-week mortality was 60.2% in patients who had a high Child-Pugh score (≥9) and advanced BCLC stage (C-D), much higher than in those with low Child-Pugh score (<9) and earlier BCLC stage (0-B) (P < 0.001).

Conclusion

Among patients with cirrhosis and AVB, patients with HCC had significantly worse outcomes than those without. The severity of liver disease and the stage of HCC are the main determinants of mortality in HCC patients.

Fully Covered Stent-TIPS for Advanced HCC Patients with Portal Vein Tumor Thrombus-Related Severe Symptomatic Portal Hypertension

Purpose

Portal vein tumor thrombus (PVTT)-related severe symptomatic portal hypertension (SPH) leads to a poor prognosis in patients with advanced hepatocellular carcinoma (HCC). Traditional transjugular intrahepatic portosystemic shunt (TIPS) using covered plus bare stent can effectively relieve SPH, however, the bare segment is susceptible to obstruction due to PVTT invasion. This study aimed to evaluate the safety and efficacy of fully covered stent-TIPS (FCS-TIPS) for treatment of PVTT-related SPH in advanced HCC patients.

Patients and Methods

This retrospective study enrolled 25 patients with advanced HCC who underwent FCS-TIPS for PVTT-related severe SPH from June 2018 to January 2024. The evaluated outcomes included overall survival (OS), technical success rate, reduction in portal venous pressure gradient (PPG), stent patency rate, SPH control rate, liver function and complications.

Results

The technical success rate was 100% without perioperative deaths or severe procedure-related adverse events. The average PPG decreased by 13.4±4.6 mmHg. The overall symptom control rate of SPH was 96.0%. Variceal bleeding, ascites/hydrothorax, and enteropathy control rates were 100%, 95.0%, and 100%, respectively. Liver function showed mild improvement one month after TIPS. One patient (4.0%) experienced overt hepatic encephalopathy (OHE) and three (12.0%) patients developed shunt dysfunction during the follow-up period. None of the patients experienced shunt-induced extrahepatic metastasis. The median OS was 6.0 months and the cumulative survival rates at 3, 6, 12 months were 80.0%, 52.0% and 21.3%.

Conclusion

FCS-TIPS is safe and effective for treating PVTT-related severe SPH and can serve as a bridging therapy for advanced HCC.

Efficacy and safety of transjugular intrahepatic portosystemic shunt in patients with hepatocellular carcinoma-A systematic review and meta-analysis

BACKGROUND

Patients with hepatocellular carcinoma (HCC) and cirrhosis can present with features of severe portal hypertension, which can be worsened further by portal vein tumoral thrombosis (PVTT). Due to the technical difficulties and short survival of these patients, HCC was traditionally considered a relative contra-indication for transjugular intrahepatic portosystemic shunt (TIPS). However, there is an increasing body of evidence, mainly from China, supporting the use of TIPS in HCC. The present study aimed at analyzing the efficacy and safety of TIPS in patients with HCC.

METHODS

From 2000 through May 2023, MEDLINE, Embase and Scopus were searched for studies analyzing the outcome of TIPS in HCC. Technical and clinical success, adverse events (AE) and mortality were the main outcomes assessed. With the use of a random effects model, the event rates were combined.

RESULTS

Total 19 studies with 1498 patients were included in the final analysis. The pooled technical and clinical success rates with TIPS in HCC were 98.8% (98.0-99.7) and 94.1% (91.2-97.0), respectively. After TIPS, ascites was controlled in 89.2% (85.1-93.3) of the cases, while rebleeding was observed in 17.2% (9.4-25.0) of cases on follow-up. The pooled incidence of overall AE, serious AE and post-TIPS hepatic encephalopathy (HE) was 5.2% (2.5-7.9), 0.1% (0.0-0.4) and 25.1% (18.7-31.5), respectively. On follow-up, 11.9% (7.8-15.9) of the patients developed shunt dysfunction requiring re-intervention.

CONCLUSION

The present analysis supports the feasibility, safety and efficacy of TIPS in the management of portal hypertension in patients with HCC.

Transjugular Intrahepatic Portosystemic Shunt for Advanced Hepatocellular Carcinoma With Main Portal Vein Tumor Thrombus-Related Symptomatic Portal Hypertension

Background and aims

The safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of symptomatic portal hypertension (SPH) caused by hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) of main trunk remains unclear. The purpose of this study was to initially explore the safety and efficacy of TIPS for SPH caused by HCC with PVTT of main trunk.

Methods

This retrospective study analyzed 16 patients who underwent TIPS for SPH caused by HCC with PVTT of main trunk. The evaluated outcomes were technical success rate, SPH control rate, stent patency rate, overall survival (OS), and complications.

Results

From July 2018 to February 2023, sixteen consecutive HCC patients with PVTT of main trunk and SPH were retrospectively identified. Technical success was 93.75 %. All patients had complete or partial remission of clinical symptoms, and there were no incidents of acute variceal rebleeding and re-exacerbation of ascites during follow-up. There had no intraoperative TIPS-related complications occurred. One patient developed mild hepatic encephalopathy after TIPS placement during the follow-up period. During follow-up, 13 of 16 patients died of advanced HCC progression, the median OS was 10.0 months, and the cumulative OS of 0.5-, 1-, and 2 years were 66.67 %, 45.00 %, and 11.25 %, respectively.

Conclusions

TIPS for SPH caused by HCC with PVTT of main trunk may be safe and effective.

Emergent TIPS for acute gastroesophageal variceal bleeding in cirrhotic patients with hepatocellular carcinoma

OBJECTIVES

To estimate the safety and effectiveness of emergent transjugular intrahepatic portosystemic shunt (TIPS) creation for acute variceal bleeding (AVB) in cirrhotic patients with hepatocellular carcinoma (HCC).

MATERIALS AND METHODS

Data of thirty-three patients with AVB and HCC undergoing emergent TIPS creation from January 2016 to January 2022 were enrolled and were retrospectively analyzed. The primary outcomes were the safety of emergent TIPS creation, the bleeding control rate, and the rebleeding rate. The secondary outcomes included overall survival (OS), liver function, overt hepatic encephalopathy (HE), and shunt dysfunction.

RESULTS

Emergent TIPS creation was technically successful in 33 patients (100%) and one (3.0%) patient suffered a major procedure-related adverse event. The control rate of bleeding (within 5 days) was 100%. During a median follow-up period of 26.3 months, rebleeding occurred in 6 (18.2%) patients. The median OS was 20.0 months. The 6-week and 1-year survival rates were 87% and 65%, respectively. Laboratory tests showed no significant impairment of liver function following TIPS creation. The incidences of overt HE and shunt dysfunction were 24.2% and 6.1%, respectively.

CONCLUSION

Emergent TIPS creation is feasible and effective for treatment of AVB in cirrhotic patients with HCC.

Risks and benefits of TIPS in HCC and other liver malignancies: a literature review

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) is a well-validated treatment option for clinically significant portal hypertension (CSPH) in the context of liver cirrhosis. Its high efficacy and safety in the management of treatment-refractory ascites and variceal bleeding have been extensively proven. Contraindications for TIPS include severe right heart failure, hepatic encephalopathy, and sepsis. However, the role of liver malignancy in TIPS is debatable. Mostly, primary liver malignancies such as hepatocellular carcinoma (HCC) emerge from advanced liver diseases. Coexisting portal hypertension in HCC often results in limited treatment options and a poor prognosis. Previous studies have shown that TIPS implantation in patients with HCC is technically feasible and is usually not associated with major adverse events. Furthermore, TIPS may help in bridging the time to liver transplantation in early HCC and allow for locoregional treatment in advanced HCC. However, several studies suggest that seeding tumour cells to the lungs by TIPS placement might worsen the prognosis.

CONCLUSIONS

TIPS placement in patients with coexisting liver malignancy remains a case-by-case decision, and there is no profound evidence allowing general recommendations. This review aims to provide a state-of-the-art overview of the potential risks and benefits of TIPS placement in patients with liver malignancies.

Transjugular intrahepatic portosystemic shunt in patients with hepatocellular carcinoma: A systematic review

BACKGROUND/AIMS

Transjugular intrahepatic portosystemic shunts (TIPS) in patients with hepatocellular carcinoma (HCC) may improve access to curative therapies, treat portal hypertension (PH)-related complications without worsening liver function, and increase overall survival. Data on the efficacy and safety of TIPS to treat PH complications in HCC patients, as well as the HCC treatment response, were evaluated.

METHODS

Studies reporting efficacy in controlling bleeding/ascites or response to HCC therapy, safety, and survival in patients with HCC and TIPS were searched systematically on PubMed and Embase. An extraction of articles using predefined data fields and quality indicators was used.

RESULTS

We selected 19 studies and found 937 patients treated for ascites/bleeding and 177 evaluating HCC treatment response. Over half were under 5 cm and solitary lesions, and most studies included tumours with portal vein thrombosis. Regarding PH studies, TIPS resolved bleeding/ascites in >60% of patients, more effective for bleeding. There were no lethal complications reported and procedural bleeding occurred in <5%. Hepatic encephalopathy occurred in 15%-30% within three months. In the HCC treatment-response studies, major complication rates were low with no mortality. In the studies that evaluated the response to transarterial chemoembolization, complete response rate of patients with TIPS varied from 16% to 75%. Liver transplantation rate varied from 8% to 80%, with >40% rate in half of the studies.

CONCLUSIONS

In the published studies, TIPS is effective in treating PH complications in patients with HCC. Prospective studies on TIPS placement in patients with HCC are urgently needed to evaluate the efficacy and safety of TIPS in this setting.

The Role of Transjugular Intrahepatic Portosystemic Shunt (TIPS) in Treating Portal Hypertension in Patients with Hepatocellular Carcinoma

Liver cancer is very frequent, and hepatocellular carcinoma (HCC) accounts for the majority of liver cancer cases. Its growing incidence has been greatly affected by the increasing prevalence of metabolic-associated fatty liver disease (MAFLD). The latter is a new epidemic in our era. In fact, HCC is often generated from noncirrhotic liver and its treatment benefits from surgical and nonsurgical approaches, potentially bridged by transjugular intrahepatic portosystemic shunt (TIPS) use. TIPS use is an effective treatment for portal hypertension complications, but its application in patients with HCC and clinically significant portal hypertension (CSPH) remains controversial due to concerns about tumor rupture, dissemination, and increased toxicity. The technical feasibility and safety of TIPS use in HCC patients have been evaluated in several studies. Despite concerns about intraprocedural complications, retrospective studies have shown high success rates and low complication rates in TIPS placement for HCC patients. TIPS use in combination with locoregional treatments, such as transarterial chemoembolization (TACE) or transarterial radioembolization (TARE), has been explored as a treatment option for HCC patients with portal hypertension. These studies have shown improved survival rates in patients undergoing TIPS in combination with locoregional treatments. However, the efficacy and toxicity of TACE in combination with TIPS use require careful evaluation, as changes in venous and arterial flow can affect treatment outcomes and complications. The results from studies evaluating the impact of TIPS on systemic therapy and surgical options are also promising. In conclusion, the TIPS is a sufficiently safe, useful item available for physicians treating complications of portal hypertension. Moreover, a TIPS can be used in combination with locoregional therapy in HCC patients. Systemic chemotherapy can also benefit of the use of TIPS placement. A complex interplay affects TIPS use with surgery. The latter needs further data. The TIPS is a useful and safe add-on treatment, changing the natural course of HCC progression. Its use is regulated by a sophisticated physiologic and pathophysiologic flow of evidence.

Emergent Transjugular Intrahepatic Portosystemic Shunt Creation for Acute Gastric Variceal Bleeding in Patients with Hepatocellular Carcinoma

A total of 42 cirrhotic patients (mean age, 51.7 years ± 10.8; 38 men) with hepatocellular carcinoma who underwent emergent transjugular intrahepatic portosystemic shunt (TIPS) creation for controlling acute gastric variceal bleeding (GVB) were included in this multicenter retrospective study. Of these, 37 (88.1%) patients underwent emergent TIPS creation as the first-line treatment to control acute GVB. Five (11.9%) patients underwent emergent TIPS creation as a rescue/salvage treatment to control acute GVB after emergent endoscopic therapy and pharmacotherapy. Emergent TIPS creation was technically successful in 40 (95.2%) patients. Two (4.8%) patients had severe and moderate procedural adverse events. The median follow-up duration was 16.9 months (range, 0.1-100.8 months). Failure to control acute bleeding and failure to prevent rebleeding occurred in 8 (19.0%) patients during follow-up. Eighteen (42.9%) patients died during follow-up. Three (7.1%) patients had shunt dysfunction during follow-up. Overt hepatic encephalopathy occurred in 6 (14.3%) patients during follow-up.

Transjugular intrahepatic portosystemic shunt for the management of symptomatic malignant pseudocirrhosis

BACKGROUND

Pseudocirrhosis is defined by radiologic changes of the liver parenchyma secondary to metastatic disease and/or cancer treatments, and portends a high rate of morbidity and mortality from sequelae of portal hypertension. Transjugular intrahepatic portosystemic shunt (TIPS) is an effective treatment for portal hypertension; however, TIPS is relatively contraindicated in the setting of hepatic metastases. The study aims to determine the technical efficacy and clinical outcomes of patients undergoing TIPS for symptomatic pseudocirrhosis.

METHODS

Retrospective analysis of patients with hepatic malignancy who underwent TIPS between 2008 and 2020 at a single tertiary care center. Patients with imaging findings of pseudocirrhosis and without history of primary liver malignancy or confounding causes of cirrhosis were included. West Haven scores assessing hepatic encephalopathy were obtained from chart review. Technical success was defined as successful TIPS creation with reduction in the portosystemic gradient (PSG). Clinical success was defined as resolution of variceal bleeding and/or ascites.

RESULTS

Nine patients (4 female/5 male), average (± SD) age 61.2±9.5 years with metastatic pseudocirrhosis were included for analysis. Primary malignancy was colorectal adenocarcinoma (n=5), neuroendocrine tumor (n=3), and malignant endothelial hemangioendothelioma (n=1). Average Model for End Stage Liver Disease (MELD-Na) score was 15.7±3.7. Technical success was 8/9 (89%) with average PSG reduced from 23.5±11.0 to 6.5±2.8 mmHg (P=0.001). Clinical success was 6/9 (67%). Two patients required TIPS revision after initial clinical success. Mild-moderate HE occurred in 6/9 patients post TIPS (67%), with a highest West Haven score of 2. Time from TIPS to death for acute variceal bleeding and ascites was 4.9±4.2 and 12±16.5 months, respectively. Cause of death was disease progression (n=5), variceal bleeding (n=1), or unavailable (n=2).

CONCLUSIONS

TIPS in the setting of malignant pseudocirrhosis can be created safely with similar clinical outcomes to TIPS performed for benign disease. Rates of low-grade hepatic encephalopathy may be higher amongst patients undergoing TIPS for pseudocirrhosis.
