Safety and Prognosis of Transarterial Chemoembolization for Octogenarians with Hepatocellular Carcinoma

A Rare Early-Onset Fatal Complication after Transarterial Chemoembolization: A Case Report and Review of the Literature

Transarterial chemoembolization (TACE) is a minimally invasive treatment for liver cancer, often employed as a bridging therapy or destination treatment for non-operable cases. This case report discusses an 82-year-old woman with a large hepatocellular carcinoma (HCC) who underwent elective TACE due to the high surgical risk associated with her tumor size. Unexpectedly, the patient experienced liver rupture 20 h post-procedure, leading to acute surgical intervention. Despite successful hemostasis during surgery, the patient succumbed to progressive multi-organ failure. We aimed to search the PubMed database for documented cases of ruptured HCC after TACE. This study highlights risk factors for spontaneous HCC rupture and specific factors associated with TACE-induced rupture. Transarterial embolization (TAE) is currently favored as the treatment method for spontaneous ruptures, while the optimal therapy for TACE-induced ruptures remains unclear. In conclusion, this case underscores the importance of recognizing the rare complication of HCC rupture post-TACE and the need for personalized risk assessment. While TAE emerges as a primary treatment choice, the lack of consensus necessitates further studies to establish evidence-based approaches for managing this uncommon yet life-threatening complication.

Impact of body composition on the prognosis of hepatocellular carcinoma patients treated with transarterial chemoembolization: A systematic review and meta-analysis

Objectives

To summarize current evidence about the influence of body composition on the prognosis of patients with hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE) treatment.

Methods

Public databases were systematically searched to identify relevant studies published from the inception of the database up to May 2023. Studies that evaluated the association between body composition and clinical outcomes in HCC patients who underwent TACE were included. A pre-designed table was applied to summarize relevant information. Meta-analysis was performed to estimate the association of body composition with overall survival.

Results

Fourteen studies were included in this review, including 3631 patients (sample size range: 56-908, median 186). All body composition measurements (including skeletal muscle area, visceral and subcutaneous adipose area, and bone mineral density) were based on computer tomography. The commonly used parameter was skeletal muscle index at 3rd lumbar vertebra level (8/14). Three studies evaluated the correlations of body composition changes with the prognosis after TACE. Most studies (12/14) identified body composition parameters as an independent indicator for overall survival, progression-free survival, and treatment response rate. The hazard ratio of different body composition parameters ranged from 1.01 to 2.88, and hazard ratio of body composition changes ranged from 1.88 to 5.93. The pooled hazard ratio of sarcopenia for overall survival was 1.38 (95 %CI: 1.20-1.58).

Conclusions

Body composition seems to be an important prognostic factor for a poorer clinical outcome after TACE treatment in patients with hepatocellular carcinoma. Future prospective studies with a larger sample size are required to confirm these findings.

Safety and Effectiveness of Transarterial Chemoembolization in Hepatocellular Carcinoma Patients Aged Greater versus Less Than 80 Years

Background

Population aging has emerged as a pressing global concern and a significant medical challenge. The use of transarterial chemoembolization (TACE) has been extensively employed for managing unresectable hepatocellular carcinoma (HCC). However, there is limited evidence regarding the safety and effectiveness of TACE specifically in individuals aged 80 years and above.

Aim

To examine the safety and effectiveness of TACE in elderly patients (≥ 80 years) compared to younger patients (< 80 years) with HCC, and the potential risk factors that may impact the progression-free survival (PFS) for TACE were also identified.

Methods

A retrospective analysis was conducted on a consecutive cohort of unresectable HCC patients who were initially treated with TACE. The patients were categorized into two groups based on the age at which they underwent TACE, and the efficacy and safety of the treatment were evaluated. The PFS was investigated, and the prognostic factors were analyzed using the Kaplan-Meier method and Cox proportional hazard models.

Results

A total of 198 patients were included in this study, with 44 patients aged 80 years or older and 154 patients younger than 80 years. The cumulative risk of PFS after TACE was similar between the two groups (P = 0.800). In the multivariate analysis, a lower ECOG score (P = 0.039) and an earlier BCLC stage (P = 0.004) were identified as independent predictors of better PFS. Patients in both groups tolerated the TACE treatment well.

Conclusion

The impact of aging on poor PFS is not significant. In patients with HCC, TACE therapy is both safe and effective for octogenarians, similar to younger patients. Furthermore, the better PFS is associated with a low ECOG score and an early BCLC stage.

Geriatric nutritional risk index as a prognostic factor in patients with hepatocellular carcinoma following transarterial chemoembolization: A retrospective study

The geriatric nutritional risk index (GNRI) has been shown to be associated with the prognosis of cancer patients except for hepatocellular carcinoma (HCC) patients after transarterial chemoembolization (TACE). Our aim is to examine the association between the GNRI and long-term prognosis in patients with HCC who underwent TACE. Patients with HCC who underwent TACE were enrolled. The relationship between the patient characteristics and GNRI were compared, and the independent prognostic factors were investigated. Nomogram performance was assessed via the concordance index (C-index) and calibration plots. Decision curve analysis (DCA) was performed to evaluate the net benefit of the nomogram. A total of 235 patients met the inclusion criteria. Compared with the parameters of the high GNRI group, low GNRI was significantly associated with hypertension, ascites, body mass index, tumor size, anemia, Child-Turcotte-Pugh class. The univariate analysis demonstrated that overall survival (OS) was inferior when GNRI < 98, tumor size ≥ 5cm, vascular invasion, alpha-fetoprotein level ≥ 400, Barcelona clinical liver cancer stage B to C and TACE times < 3. The multivariate analysis revealed that GNRI < 98, tumor size ≥ 5cm, tumor number ≥ 2, alpha-fetoprotein level ≥ 400 and TACE times < 3 were independent predictors of a poor OS. In the validation step, OS was shown to be well calibrated (C-index = 0.724), and a satisfactory clinical utility was proven by DCA. Low GNRI score was associated with a shorter OS in patients undergoing TACE.

Safety and Efficacy of Transarterial Chemoembolization in Elderly Patients with Intermediate Hepatocellular Carcinoma

(1) Introduction: Transarterial chemoembolization (TACE) is the most widely used treatment for intermediate hepatocellular carcinoma (HCC), with limited data available in elderly patients. This study compares the safety and efficacy of TACE for HCC in elderly patients (≥70 years) versus younger patients (<70 years). (2) Materials and Methods: Patients treated by a first TACE for HCC at Grenoble-Alpes University Hospital from January 2012 to March 2017 were included. The primary objective was to compare the safety and predictive factors of serious adverse events between groups using univariate and multivariate analyses. Secondary objectives included tumor response and survival analyses. (3) Results: 271 patients were included: 88 elderly and 183 under 70 years. A total of 20.5% of elderly patients experienced serious adverse events versus 21.3% of patients under 70 (p = 0.87). The predictive factors of serious adverse events were Child−Pugh ≥ B7 (p < 0.0001), ECOG ≥ 1 (p = 0.0019), and MELD ≥ 9 (p = 0.0415). The serious adverse event rate was not increased with age (p = 0.87). The objective tumor response rate was 89.5% in elderly versus 78.7% in younger patients (p = 0.03). (4) Conclusion: This study showed similar safety profiles of the first TACE between elderly and younger patients, with comparable efficacy outcomes, suggesting that advanced age should not constitute a limitation in itself in treatment decision-making.

Management of intermediate-stage hepatocellular carcinoma in the elderly with transcatheter arterial chemoembolization failure: Retreatment or switching to systemic therapy?

BACKGROUND

Transcatheter Arterial chemoembolization (TACE) is the first-line option for the intermediate-stage hepatocellular carcinoma. Guidelines do not define the number of TACE sessions to be repeated before stopping treatment and switching to sorafenib.

METHODS

We retrospectively analysed 76 patients aged ≥65 years who were treated by multiple TACE sessions (re-TACE group; N = 36 patients) or one TACE session followed by sorafenib (TACE/Sorafenib group; N = 40 patients). The primary outcome was the overall survival (Kaplan-Meier analysis and log-rank test).

RESULTS

Median overall survival was 320 days (range: 70-420 days) in re-TACE subgroup and 285 days (range: 50-368 days) in TACE/Sorafenib subgroup without significant differences between the two groups (log-rank test P = .72; HR = 0.87; 95% IC 0.41-1.87). The survival rate at one year was 43.6% and 32% in the re-TACE and in the TACE/sorafenib groups (P = .12), respectively. Subgroup analysis by gender, number of nodules at baseline and etiology of liver cirrhosis was performed but no differences were found. No statistical difference was observed in the frequency of side effects, but sorafenib was associated with severe diarrhoea in most patients requiring dose reduction.

CONCLUSION

In our study including HCC patients aged ≥65 years, no differences in survival rate and side effects were found between patients Retreated with further TACE sessions and patients with treatment stage migration to sorafenib after first TACE failure. We included in our analysis a small study population; therefore, larger prospective studies are needed to confirm these findings.

How to Treat Hepatocellular Carcinoma in Elderly Patients

Hepatocellular carcinoma (HCC) is the primary tumour of the liver with the greatest incidence, particularly in the elderly. Additionally, improvements in the treatments for chronic liver diseases have increased the number of elderly patients who might be affected by HCC. Little evidence exists regarding HCC in old patients, and the elderly are still underrepresented and undertreated in clinical trials. In fact, this population represents a complex subgroup of patients who are hard to manage, especially due to the presence of multiple comorbidities. Therefore, the choice of treatment is mainly decided by the physician in the clinical practice, who often tend not to treat elderly patients in order to avoid the possibility of adverse events, which may alter their unstable equilibrium. In this context, the clarification of the optimal treatment strategy for elderly patients affected by HCC has become an urgent necessity. The aim of this review is to provide an overview of the available data regarding the treatment of HCC in elderly patients, starting from the definition of "elderly" and the geriatric assessment and scales. We explain the possible treatment choices according to the Barcelona Clinic Liver Cancer (BCLC) scale and their feasibility in the elderly population.

Role of tumor margin and ADC change in defining the need for additional treatments after the first TACE in patients with unresectable HCC

PURPOSE

To define the number of TACE sessions needed to improve patients' overall survival (OS) in different subgroups of unresectable HCC.

METHODS

This retrospective cohort included 180 patients who got TACE between 2005-2016 as the initial treatment for unresectable HCC. Tumor margin (well- vs. ill-defined) was determined by two radiologists at baseline. Well-defined group was divided into two groups (ADC-responders vs. ADC-nonresponders) based on %ADC change (ΔADC-cutoff = 25 %). Accordingly, patients were categorized into three groups, ill-defined, well-defined ADC-responders, or well-defined ADC-nonresponders. Cox-analysis was used to compare the survival benefit of multiple TACE in different groups.

RESULTS

Ill-defined HCC (n = 108) was associated with worse survival (HR = 1.95,p < 0.001). Multiple TACE were associated with increased OS (HR = 0.88,p = 0.033) in these patients, with significant survival improvement after ≥4TACE. ΔADC was not related to OS in ill-defined group. In well-defined group (n = 72), multiple TACE were not associated with improved OS (HR = 0.181,p = 0.090). These patients were categorized into two groups based on ΔADC-cutoff. ADC-responders (ΔADC≥25 %) had the longest survival than other groups(p = 0.015). Multiple TACE sessions were not associated with better OS in this group (HR = 1.004,p = 0.982). By contrast, incremental number of TACE were associated with significantly longer OS in ADC-nonresponders (ΔADC<25 %) (HR = 0.79,p = 0.034). These patients' OS significantly improved after ≥3TACE.

CONCLUSION

The survival benefit of sequential TACE sessions varies for different HCC subgroups. There was no significant survival benefit associated with multiple TACE in well-defined lesions responding to the first TACE. The most survival benefit was for ADC-nonresponder well-defined group and it was least for ill-defined HCC group, regardless of ADC-response.

Transarterial- chemoembolization remains an effective therapy for intermediate-stage hepatocellular carcinoma with preserved liver function

AIM

To evaluate outcomes as well as prognostic factors of transarterial chemoembolization (TACE) in intermediate-stage hepatocellular carcinoma (HCC) with preserved liver function to determine positioning of TACE.

METHODS

Of 158 treatment-naïve patients with intermediate-stage HCC who received initial TACE from February 2007 to January 2016, 113 patients met the following inclusion criteria: no combined therapy within 4 weeks after initial TACE, and Child-Pugh score under 7. Response rate and overall survival were evaluated. The prognostic factors were investigated in univariate and multivariate analyses using Cox proportional hazards models. The deterioration of liver function after repeated TACE was also evaluated.

RESULTS

The response rate was 92.7% (complete response, 63.3%; partial response, 29.4%). The median survival time was 45.2 months. Survival rates at 1, 2, and 3 years were 90.4%, 77.0%, and 60.8% respectively. Age ≥ 75 years (P = 0.022), serum α-fetoprotein level ≥ 200 ng/mL (P = .010), tumor number ≥ 11 (P = 0.008), and heterogeneous enhancement on dynamic computed tomography (P = 0.024) were poor prognostic factors. The deterioration rate of Child-Pugh score and albumin-bilirubin grade was 18.5% and 12.3%, respectively, after the first TACE, 15.6% and 5.1%, respectively, after the second TACE, and 14.5% and 11.1%, respectively, after the third TACE.

CONCLUSION

Superselective TACE can achieve high tumor response rates with prolonged overall survival for patients with intermediate-stage HCC with preserved liver function. Age, serum α-fetoprotein level, tumor number ≥ 11, and heterogeneous enhancement on dynamic computed tomography indicated significantly poor prognosis.

Survival and Tolerability of Transarterial Chemoembolization in Greater Versus less than 70 Years of Age Patients with Unresectable Hepatocellular Carcinoma: A Propensity Score Analysis

BACKGROUND

The number of elderly patients diagnosed with hepatocellular carcinoma (HCC) is progressively increasing. The aim of this study was to determine the safety and efficacy of conventional transarterial chemoembolization (TACE) in elderly HCC patients compared with younger adults.

METHODS

A consecutive cohort of unresectable HCC patients treated with TACE as a first-line treatment was retrospectively analyzed. Patients were categorized into "elderly" (≥ 70 years, 80 patients) and "younger" (< 70 years, 145 patients). Liver-related death and progression-free survival after TACE were compared before and after propensity score matching. A competing risk regression analysis was used for univariate/multivariate survival data analysis.

RESULTS

cTACE was well tolerated in both groups. The cumulative risk of both liver-related death and progression-free survival after cTACE was comparable between "elderly" and "younger" (death: 73.8% vs 69.4%, P = 0.505; progression-free survival: 48.2% vs 44.8%, P = 0.0668). Propensity model matched 61 patients in each group for gender and Barcelona Clinic Liver Cancer staging. Even after matching, the cumulative risk of liver-related death and of progression-free survival did not differ between the two groups. At multivariate analysis, Child-Pugh class, tumor gross pathology and alpha-fetoprotein were independently associated with the liver-related mortality risk.

CONCLUSIONS

This study confirms that TACE is well tolerated and effective in patients aged 70 years or more with unresectable HCC as it is for their younger counterparts (< 70 years). Liver-related mortality was not associated with age ≥ 70 years and primarily predicted by tumor multifocality, Child-Pugh class B and an increased alpha-fetoprotein value (> 31 ng/ml).

New landscapes and horizons in hepatocellular carcinoma therapy

Hepatocellular carcinoma (HCC), is the sixth most frequent form of cancer and leads to the fourth highest number of deaths each year. HCC results from a combination of environmental factors and aging as there are driver mutations at oncogenes which occur during aging. Most of HCCs are diagnosed at advanced stage preventing curative therapies. Treatment in advanced stage is a challenging and pressing problem, and novel and well-tolerated therapies are urgently needed. We will discuss further advances beyond sorafenib that target additional signaling pathways and immune checkpoint proteins. The scenario of possible systemic therapies for patients with advanced HCC has changed dramatically in recent years. Personalized genomics and various other omics approaches may identify actionable biochemical targets, which are activated in individual patients, which may enhance therapeutic outcomes. Further studies are needed to identify predictive biomarkers and aberrantly activated signaling pathways capable of guiding the clinician in choosing the most appropriate therapy for the individual patient.
