Prophylactic Endoscopic Therapy for Variceal Bleeding in Patients with Hepatocellular Carcinoma

Transarterial Chemoembolization Combined With Endoscopic Therapy Is Beneficial for Unresectable Hepatocellular Carcinoma With Esophagogastric Varices

Background

The efficacy of transarterial chemoembolization (TACE) combined with endoscopic therapy for unresectable hepatocellular carcinoma with esophagogastric varices remains unclear.

Methods

The study has been registered on ClinicalTrials.gov with the number NCT05017922 (https://register.clinicaltrials.gov). Eligible patients were divided into combined group (received TACE plus endoscopic therapy) and control group (only received TACE). The occurrence of death and bleeding episodes during the follow-up was recorded. Kaplan–Meier analysis was used to compare outcomes between the two groups. Cox proportional hazard model was used to determine independent predictors for the survival.

Results

Eighty-nine patients were included, 42 in the combined group, others in the control group. During the follow-up, 51 patients died, the 1-year, 2-year, and 3-year survival rates were 64.9%, 45.5%, and 34.5%. The cumulative survival was significantly higher in the combined group than in the control group (p = 0.027); the 1-year, 2-year, and 3-year survival rates were 75.5%, 55.9%, 43.8% and 55.0%, 35.9%, 26.6%, respectively. Forty-four patients experienced bleeding, the bleeding rate was significantly higher in the control group than in the combined group (77.4% vs. 56.8%, p = 0.016). Multivariate analysis showed that treatment, hemoglobin, portal vein tumor thrombosis, and aspartate aminotransferase were independent predictors for overall survival; the first three factors were also independent predictors for bleeding-free survival. Patients who received primary prophylaxis had longer overall survival (p = 0.042) and bleeding-free survival (p = 0.029) than those who received secondary prophylaxis.

Conclusions

TACE combined with endoscopic therapy significantly improved survival and reduced bleeding rates in unresectable hepatocellular carcinoma with esophagogastric varices patients. Portal vein tumor thrombosis was a strong negative prognostic factor for both overall survival and bleeding-free survival. Primary prophylaxis improved survival benefits compared with secondary prophylaxis.

Transjugular intrahepatic portosystemic shunt versus endoscopic therapy for prevention of variceal rebleeding in patients with hepatocellular carcinoma meeting the Milan criteria

OBJECTIVE

Transjugular intrahepatic portosystemic shunt (TIPS) and endoscopic therapy (ET) have been recommended to prevent variceal rebleeding due to cirrhotic portal hypertension. However, which one is better for patients with hepatocellular carcinoma (HCC) remains controversial. Hence, we aimed to compare the clinical outcomes of these two treatments for these subpopulation.

METHODS

This retrospective study was approved by the institutional review board. The data of 98 consecutive patients with HCC meeting the Milan criteria (mean age 54.1 years) who had received TIPS placement (34 patients) or ET (64 patients) between June 2010 and December 2017 were reviewed. The clinical outcomes were evaluated and were calculated by the Kaplan-Meier method and compared by using the log-rank test. A matched cohort composed of 34 patients from each group was selected after adjustment with propensity score matching to verify the robustness of the results.

RESULTS

The median follow-up time was 33.1 months. The rebleeding rate was significantly lower in TIPS group (P = 0.016). A matched cohort composed of 34 patients from each group after adjustment with propensity score matching showed that TIPS reduced the risk of rebleeding (P = 0.030) without increasing long-term overt hepatic encephalopathy (P = 0.151), while there was no significant difference in overall liver transplant-free survival (P = 0.120). Thereafter, 25 patients in TIPS group (73.5%) and 42 patients in ET group (65.6%) received locoregional therapies for HCC (P = 0.431).

CONCLUSION

TIPS reduced the risk of rebleeding without improving survival. Locoregional therapies can be performed safely to manage HCC after sufficient prevention of variceal rebleeding.
