Cause-specific mortality associated with aging in patients with hepatocellular carcinoma undergoing percutaneous radiofrequency ablation

Combination of psoas muscle mass index and neutrophil-to-lymphocyte ratio as a noninvasive prognostic marker in hepatocellular carcinoma patients undergoing radiofrequency ablation

AIM

The psoas muscle index (PMI) and neutrophil-to-lymphocyte ratio (NLR) have been reported as useful noninvasive prognostic markers in patients with hepatocellular carcinoma (HCC). The usefulness of the combination of the PMI and NLR as a prognostic marker in HCC patients undergoing radiofrequency ablation (RFA) is unclear.

METHODS

We retrospectively analyzed the PMI and NLR in 112 patients undergoing RFA, including 40 patients aged 75 years and older (36%). The influence of the PMI and NLR on disease-free survival and overall survival (OS) was analyzed.

RESULTS

There were 66 patients with high PMI and low NLR values (58%), 36 patients with a low PMI or high NLR value (32%), and 10 patients with low PMI and high NLR values (9%). The combination of the PMI and NLR did not show a significant association with the disease-free survival rate. For patients aged ≥75 years, those with both low PMI and high NLR values showed significantly shorter OS periods (log-rank: P < 0.001). In the multivariate analysis, the combination of a low PMI value and high NLR value was significantly associated with shorter survival periods (hazard ratio: 19.72; 95% confidence interval, 4.933-78.8; P < 0.001).

CONCLUSION

In this study, the combination of PMI and NLR was associated with prognosis in patients with early HCC and preserved liver function. The combination of the PMI and NLR may be a useful and noninvasive prognostic marker in HCC patients aged 75 years and older, as well as in younger patients.

Stereotactic body radiation therapy for elderly patients with small hepatocellular carcinoma: a retrospective observational study

Background/Aim

We aimed to investigate the efficacy and safety of stereotactic body radiation therapy (SBRT) in elderly patients with small hepatocellular carcinomas (HCC).

Methods

Eighty-three patients (89 lesions) with HCC who underwent SBRT between January 2012 and December 2018 were reviewed in this retrospective observational study. The key inclusion criteria were as follows: 1) age ≥75 years, 2) contraindications for hepatic resection or percutaneous ablative therapies, 3) no macroscopic vascular invasion, and 4) no extrahepatic metastasis.

Results

The patients were 75-90 years of age, and 49 (59.0%) of them were male. Most patients (94.0%) had an Eastern Cooperative Oncology Group performance status of 0 or 1. Seventy-four patients (89.2%) had Child-Pugh class A hepatic function before SBRT. The median tumor size was 1.6 cm (range, 0.7-3.5). The overall median follow-up period was 34.8 months (range, 7.3-99.3). The 5-year local tumor control rate was 90.1%. The 3-year and 5-year overall survival rate was 57.1% and 40.7%, respectively. Acute toxicity grade ≥3 was observed in three patients (3.6%) with elevated serum hepatic enzymes; however, no patient experienced a worsening of the Child-Pugh score to ≥2 after SBRT. None of the patients developed late toxicity (grade ≥3).

Conclusions

SBRT is a safe treatment option with a high local control rate in elderly patients with small HCC who are not eligible for other curative treatments.

Influence of Demographic Factors on Long-Term Trends of Premature Mortality and Burden Due to Liver Cancer: Findings From a Population-Based Study in Shanghai, China, 1973–2019

Objective

Liver cancer is one of the most common causes of cancer-related death. Understanding how demographic factors influence mortality due to liver cancer is crucial for optimizing disease-control strategies. We aimed to characterize the long-term trends in the mortality and years of life lost (YLL) of liver cancer in Shanghai, China, 1973–2019, and quantitatively analyze the contributions of demographic and non-demographic factors on the mortality of liver cancer.

Methods

Using mortality data from the Mortality Registration System of Pudong New Area, the largest district of Shanghai with a population of permanent resident of 5.68 million, during 1973–2019, we analyzed the temporal trends for the mortality rates and YLL by Joinpoint Regression Program. The difference decomposition method was employed to estimate the increasing mortality rates related to demographic and non-demographic factors.

Results

A total of 21,530 deaths from liver cancer occurred from 1973 to 2019. The crude mortality rates (CMR) and age-standardized mortality rate by Segi's world standard population (ASMRW) of liver cancer were 26.73/10⁵ person-years and 15.72/10⁵ person-years, respectively. The CMR, ASMRW, and YLL rates of liver cancer showed significantly decreasing trends in males, females and the total population from 1973 to 2019, whereas the upward trends in the YLL were seen in males, females and the total population (all P < 0.05). A significant upward trend was observed in the increased CMR caused by demographic factors, but the changing rate caused by non-demographic factors decreased.

Conclusions

The CMR and ASMRW of liver cancer continually decreased although YLL increased during 1973–2019 in Pudong New Area, Shanghai. The demographic factors, especially aging, might be responsible for the increase in the mortality of liver cancer. More effective prevention strategies tailored to liver cancer are needed to further reduce its disease burden in the elderly population.

Impact of aging on primary liver cancer: epidemiology, pathogenesis and therapeutics

Aging involves progressive physiological and metabolic reprogramming to adapt to gradual deterioration of organs and functions. This includes mechanisms of defense against pre-malignant transformations. Thus, certain tumors are more prone to appear in elderly patients. This is the case of the two most frequent types of primary liver cancer, i.e., hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA). Accordingly, aging hallmarks, such as genomic instability, telomere attrition, epigenetic alterations, altered proteostasis, mitochondrial dysfunction, cellular senescence, exhaustion of stem cell niches, impaired intracellular communication, and deregulated nutrient sensing can play an important role in liver carcinogenesis in the elders. In addition, increased liver fragility determines a worse response to risk factors, which more frequently affect the aged population. This, together with the difficulty to carry out an early detection of HCC and iCCA, accounts for the late diagnosis of these tumors, which usually occurs in patients with approximately 60 and 70 years, respectively. Furthermore, there has been a considerable controversy on what treatment should be used in the management of HCC and iCCA in elderly patients. The consensus reached by numerous studies that have investigated the feasibility and safety of different curative and palliative therapeutic approaches in elders with liver tumors is that advanced age itself is not a contraindication for specific treatments, although the frequent presence of comorbidities in these individuals should be taken into consideration for their management.

Polymorphisms in xenobiotic metabolism-related genes in patients with hepatocellular carcinoma: a case-control study

This study was performed to investigate the relationship between polymorphisms in microsomal epoxide hydrolase (mEH; Tyr113His and His139Arg substitution) and glutathione S-transferase (GST; GSTM1 deletion, GSTT1 deletion, and GSTP1.Ala114Val substitution) and their correlation with clinico-histopathological features in hepatocellular carcinoma (HCC).We evaluated environmental risk factors and genetic alterations in 556 individuals (86 cases and 470 controls). PCR multiplex for GSTM1 and GSTT1, polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) for GSTP1, and real-time PCR for mEH were performed. Statistical analyses were performed using multiple logistic regression tests.Age over 48 years (p < 0.001) and alcohol consumption (p = 0.021) were the predictors of increased risk of developing HCC. GSTP1.Ala114Val for all regression models (p < 0.05), except the recessive model, and the GSTT1 null genotype (odds ratio [OR] = 0.43, 95% confidence interval [CI] = 0.21-0.87, p = 0.019) were predictors of an increased risk of developing HCC. Polymorphic GSTT1, GSTM1, GSTP1.Ala114Val, and mEH.His139Arg and wild-type mEH.Tyr113His (OR = 5.04; 95% CI = 1.59-16.04; p = 0.006) were associated with HCC.Age over 48 years, alcohol consumption, and the presence of polymorphic variants of GSTP1 and GSTT1 were associated with the risk of developing HCC.

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.

Risk factors of mortality in the patients with hepatocellular carcinoma: A multicenter study in Indonesia

BACKGROUND AND AIMS

Hepatocellular carcinoma (HCC) is considered a significant burden, and its associated rate of mortality is increasing. Therefore, a population-based cancer registry is considered an essential element in the baseline and comprehensive analysis of the risk factors associated with HCC. We present a multicenter analysis of HCC registry from 2 hospitals in Indonesia.

METHODS

We performed a follow-up on patients with HCC who were admitted between January 2015 and November 2017 in Cipto Mangunkusumo National General Hospital and Dharmais Hospital, Jakarta, Indonesia. Patient's death was considered the primary outcome of the study. A multivariate analysis was conducted using logistic regression, and odds ratio (OR) with 95% confidence intervals (CIs) were calculated.

RESULTS

A total of 282 patients with HCC included. At the last follow-up, 136 (48.2%) patients had died. Mortality rate was not significantly affected by sex, age, etiology, the presence of cirrhosis, nor surveillance of HCC. Based on the Child-Pugh (CP) classification, the OR increased progressively in CP C patients (OR 1.95; 95% CI 1.08-3.53; P = 0.026). The progressive increase was also found in patients with a higher Barcelona Clinic Liver Cancer stage, and the OR for CP C and D patients were 3.50 (95% CI 1.18-10.38; P = 0.024) and 3.41 (95% CI 1.02-11.41; P = 0.047), respectively. Supportive treatment was the most common treatment modality with an OR of 2.17 (95% CI 1.14-4.16; P = 0.019), and it was associated with the mortality rate of HCC.

CONCLUSIONS

The CP classification, Barcelona Clinic Liver Cancer staging system, and treatment modality might predict mortality in patients with HCC. Moreover, other parameters must be further evaluated.

Hepatocellular carcinoma in the elderly: Meta-analysis and systematic literature review

AIM: To conduct a meta-analysis to investigate the clinical outcomes of surgical resection and locoregional treatments for hepatocellular carcinoma (HCC) in elderly patients defined as aged 70 years or more.

METHODS: Literature documenting a comparison of clinical outcomes for elderly and non elderly patients with hepatocellular carcinoma was identified by searching PubMed, Ovid, Cochrane Library, and Web of Science databases, for those from inception to March 2015 with no limits. Dichotomous outcomes and standard meta-analysis techniques were used. Heterogeneity was tested by the Cochrane Q statistic. Pooled estimates were measured using the fixed or random effect model.

RESULTS: Twenty three studies were included with a total of 12482 patients. Of these patients, 6341 were treated with surgical resection, 3138 were treated with radiofrequency ablation (RFA), and 3003 were treated with transarterial chemoembolization (TACE). Of the patients who underwent surgical resection, the elderly had significantly more respiratory co-morbidities than the younger group, with both groups having a similar proportion of cardiovascular co-morbidities and diabetes. After 1 year, the elderly group had significantly increased survival rates after surgical resection compared to the younger group (OR = 0.762, 95%CI: 0.583-0.994, P = 0.045). However, the 3-year and 5-year survival outcomes with surgical resection between the two groups were similar (OR = 0.947, 95%CI: 0.777-1.154, P = 0.67 for the third year; and OR = 1.131, 95%CI: 0.895-1.430, P = 0.304 for the fifth year). Postoperative treatment complications were similar between the elderly and younger group. The elderly group and younger group had similar survival outcomes for the first and third year after RFA (OR = 1.5, 95%CI: 0.788-2.885, P = 0.217 and OR = 1.352, 95%CI: 0.940-1.944, P = 0.104). For the fifth year, the elderly group had significantly worse survival rates compared to the younger group after RFA (OR = 1.379, 95%CI: 1.079-1.763, P = 0.01). For patients who underwent TACE, the elderly group had significantly increased survival compared to the younger group for the first and third year (OR = 0.664, 95%CI: 0.548-0.805, P = 0.00 and OR = 0.795, 95%CI: 0.663-0.953, P = 0.013). At the fifth year, there were no significant differences in overall survival between the elderly group and younger group (OR = 1.256, 95%CI: 0.806-1.957, P = 0.313).

CONCLUSION: The optimal management strategy for elderly patients with HCC is dependent on patient and tumor characteristics. Compared to patients less than 70, elderly patients have similar three year survival after resection and ablation and an improved three year survival after TACE. At five years, elderly patients had a lower survival after ablation but similar survival with resection and TACE as compared to younger patients. Heterogeneity of patient populations and selection bias can explain some of these findings. Overall, elderly patients have similar success, if not better, with these treatments and should be considered for all treatments after assessment of their clinical status and cancer burden.
