Outcomes of emergent embolisation of ruptured hepatocellular carcinoma in a western population

Ruptured Hepatocellular Carcinoma: What Do Interventional Radiologists Need to Know?

Rupture of HCC (rHCC) is a life-threatening complication of hepatocellular carcinoma (HCC), and rHCC may lead to a high rate of peritoneal dissemination and affect survival negatively. Treatment for rHCC mainly includes emergency surgery, interventional therapies, and palliative treatment. However, the management of rHCC should be carefully evaluated. For patients with severe bleeding, who are not tolerant to open surgery, quick hemostatic methods such as rupture tissue ablation and TAE/TACE can be performed. We described clinical presentation, prognosis, complication, interventional management, and current evidence of rHCC from the perspective of interventional radiologists. Overall, our review summarized that interventional therapies are necessary for most patients with rHCC to achieve hemostasis, even in some patients with Child–Pugh C. Moreover, TAE/TACE followed by staged hepatectomy is a beneficial treatment for rHCC according to current clinical evidence. TAE/TACE is the first choice for most patients with rHCC, and appropriate interventional treatment may provide staged surgery opportunities for those who are not tolerant to emergency surgery to reach an ideal prognosis.

Ruptured Hepatocellular Carcinoma: Current Status of Research

Background

Ruptured hepatocellular carcinoma (rHCC) is considered a rare and life-threatening manifestation; when it happens, it often requires acute and positive intervention. At present, the mechanism of rHCC development is gradually being understood while there are many kinds of rHCC treatment. From our clinical observation, the prognosis of rHCC patients is not as poor as it is currently believed. It may not be appropriate to include all patients with rHCC in T4.

Main Body

The incidence of ruptured hepatocellular carcinoma is now rising. Especially in the Asian region, it can even reach 10% – 15%. The most common symptom of HCC rupture is abdominal pain, and there are now a variety of treatments for hepatocellular carcinoma rupture. With aggressive treatment, rHCC patients can also achieve a better prognosis. The patient’s condition varies on admission, so the treatment methods will also be different. It is critical to identify prognostic factors simultaneously, and rHCC can be effectively managed by focusing on important prognostic factors.

Conclusion

A review was carried out to analyze diagnosis, mechanism, treatment, and prognostic risk factors on this disease condition during the current situation; it is hoped that it will provide better guidance for clinicians. Moreover, patients with rHCC were managed hierarchically to prolong their prognosis.

Treatment strategies and prognosis for initially unresectable ruptured hepatocellular carcinoma: a single-center experience in 94 patients

PURPOSE

To identify the treatment options and prognostic factors for patients with initially unresectable ruptured hepatocellular carcinoma (HCC).

METHODS

Between June 2012 to December 2016, 94 consecutive patients with initially unresectable ruptured HCC were analyzed retrospectively in this study. Patients were followed until December 2017. Predictors of short-term (≤30 days) and long-term (>30 days) survival were identified by using logistic regression model and Cox proportional hazard model, respectively.

RESULTS

Of the 94 patients, initial hemostasis treatment was achieved by transarterial embolization (TAE) in 59 patients, surgical hemostasis in 14, and conservative treatment in 21. Twenty-five (26.6%) patients died within 30 d after tumor rupture. In the multivariate analysis, patients treated with aggressive initial treatment strategies (TAE or surgical hemostasis) (P < 0.001) or those with better Child-Pugh class (P = 0.003) and absence of shock on admission (P = 0.001) had a better chance of short-term survival. Of the 69 patients who survived more than 30 days after initial treatment, the median survival time was 268 d. In the multivariate analysis, among the 69 who survived, early modified LCSGJ stage (P = 0.003) and staged hepatectomy as definitive treatment (P < 0.001) were significant predictors of increased long-term survival.

CONCLUSION

Short-term survival of patients with initially unresectable ruptured HCC could achieve with better Child-Pugh class, absence of shock and aggressive initial treatment strategies. After survived the emergency phase of tumor rupture, long-term survival was significantly increased with early modified LCSGJ stage and staged hepatectomy therapy.

Emergency transarterial embolization followed by staged hepatectomy versus emergency hepatectomy for ruptured hepatocellular carcinoma: a single-center, propensity score matched analysis

PURPOSE

To compare the feasibility and efficacy of emergency transarterial embolization (TAE) followed by staged hepatectomy (SH) with emergency hepatectomy (EH) for ruptured hepatocellular carcinoma (HCC).

METHODS

Between January 2012 and December 2017, 102 patients with HCC rupture received EH or emergency TAE followed by SH in our center. Patients were followed until April 2019. Propensity score matching (PSM) analysis was used at a 1:2 ratio, resulting in 20 patients in the SH group and 40 patients in the EH group. We retrospectively compared the operative variables, recurrence status, disease-free survival (DFS), and overall survival (OS) of patients between the two matched groups.

RESULTS

Compared with the matched EH group, the SH group showed significantly decreased perioperative blood loss or blood transfusion, shortened intraoperative duration of clamping and postoperative hospital stay (P < 0.05), while achieving comparable long-term OS (SH group: 39.0 months vs. EH group: 38.1 months, P = 0.342). There was no significant difference in the peritoneal metastasis rate (SH group: 20.0% vs. EH group: 25.6%, P = 0.874), recurrence rate (SH group: 65.0% vs. EH group: 71.8%, P = 0.333) or DFS (SH group: 9.4 months vs. EH group: 7.7 months, P = 0.602) between the two matched groups.

CONCLUSION

For resectable ruptured HCC, emergency TAE of rupture which followed by SH, could bring patients about intraoperative and postoperative benefits when compared to EH. Moreover, this combination treatment will not increase the rate of peritoneal metastasis or recurrence, and might achieve favorable survival benefits for patients.

Staged partial hepatectomy versus transarterial chemoembolization for the treatment of spontaneous hepatocellular carcinoma rupture: a multicenter analysis in Korea

Purpose

The aim of this study was to identify the prognostic factors and compare the long-term outcomes of staged hepatectomy and transarterial chemoembolization (TACE) for patients with spontaneous rupture of hepatocellular carcinoma (HCC).

Methods

This study is a multicenter, retrospective analysis of patients with newly diagnosed ruptured HCC. To compare overall survival between staged hepatectomy group and TACE alone group, we performed propensity score-matching to adjust for significant differences in patient characteristics. To identify prognostic factors, the clinical characteristics at the time of diagnosis of tumor rupture were investigated using Cox-regression analysis.

Results

From 2000 to 2014, 172 consecutive patients with newly diagnosed ruptured HCC were treated in 6 Korean centers. One hundred seventeen patients with Child-Pugh class A disease were identified; of which 112 were initially treated with transcatheter arterial embolization (TAE) for hemostasis and five underwent emergency surgery for bleeder ligation. Of the 112 patients treated with TAE, 44 underwent staged hepatectomy, 61 received TACE alone, and 7 received conservative treatment after TAE. Those that underwent staged hepatectomy had significantly higher overall survival than those that underwent TACE alone before matching (P < 0.001) and after propensity score-matching (P = 0.006). Multivariate analysis showed that type of treatment, presence of portal vein thrombosis, pretreatment transfusion >1,200 mL, and tumor size >5 cm were associated with poor overall survival.

Conclusion

Staged hepatectomy may offer better long-term survival than TACE alone for spontaneous rupture of HCC. Staged hepatectomy should be considered in spontaneous rupture of HCC with resectable tumor and preserved liver function.

Development and validation of an imaging and clinical scoring system to predict early mortality in spontaneous ruptured hepatocellular carcinoma treated with transarterial embolization

PURPOSE

To develop and validate a scoring system using a combination of imaging and clinical parameters to predict 30-day mortality in ruptured HCC (rHCC) patients after transarterial embolization (TAE).

METHODS

98 consecutive patients with rHCC who underwent abdominal CT and subsequent TAE between January 2007 and December 2016 were retrospectively reviewed. The CT scans were reviewed by two radiologists blinded to the patient outcome. Clinical parameters including serum bilirubin, albumin, INR, creatinine, and hemoglobin were recorded. Independent risk factors for 30-day mortality after TAE were identified using multivariate binary logistic regression, for development of a scoring system. The scoring system was then validated in 20 patients between January 2017 and May 2018.

RESULTS

In the development cohort, bilobar tumor distribution (OR = 29.6), clinical parameters of bilirubin > 2.5 mg/dL (OR = 5.9), and albumin < 30 g/L (OR = 4.1) were independent predictors for 30-day mortality. A 6-point score was derived and yielded area-under-the-receiver-operating-characteristic-curve (AUC) of 0.904. A score ≥ 4 resulted in sensitivity of 80.5% and specificity of 91.2% for 30-day mortality. In the validation cohort, AUC for 30-day mortality was 0.939. A score ≥ 4 resulted in sensitivity of 81.2% and specificity of 88.9%. In both development and validation cohorts, the proposed scoring system was better than biochemical components of Child-Pugh score and serum bilirubin to predict 30-day mortality.

CONCLUSION

Imaging and clinical parameters can be combined into a scoring system to accurately predict 30-day mortality after TAE in rHCC patients. The score may help identify and counsel high-risk patients.

Liver radiofrequency ablation as emergency treatment for a ruptured hepatocellular carcinoma: a case report

BACKGROUND

Hemoperitoneum is a possible complication of hepatocellular carcinoma that may require emergency surgery as an alternative to radiological locoregional therapies.

CASE PRESENTATION

We present a case report of a 78-year-old white man with alcoholic-related cirrhosis and a multifocal hepatocellular carcinoma. An abdominal computed tomography scan showed multiple and bilateral foci of bleeding from broken liver cancer. He was urgently transferred from our radiology unit to our operating room for massive hemoperitoneum. A middle line laparotomy detected a massive hemoperitoneum. His liver was cirrhotic and completely subverted by a tumor; there were two spontaneous bleeding lacerations on segments II and IV, which were uncontrollable with conventional hemostatic techniques. Therefore, it was decided to carry out the coagulation of the multiple vascular afferents of each single mass by means of radiofrequency ablation cycles performed circumferentially on both nodules for a total of 40 minutes. Hemostasis was achieved; the radiofrequency ablation controlled the bleeding from his ruptured hepatocellular carcinoma. He was transferred to our intensive care unit for postoperative monitoring in terms of hemodynamic stability. On postoperative day 2 he was discharged from our intensive care unit.

CONCLUSIONS

Multifocal bleeding hepatocellular carcinoma still has an extremely high mortality. The angiographic control of multiple bilateral bleeding lesions can be extremely difficult and can be contraindicated by the location of the lesions and by the overall clinical condition of the patient. In this case, treatment with radiofrequency ablation has proven to be effective in the control of multiple and bilateral hepatic lesions. This particular technique allowed us to attack the lesion at the level of the vascular pedicle in order to control the bleeding.
