Hepatocellular carcinoma in elderly: Clinical characteristics, treatments and outcomes compared with younger adults

Immunosenescence and immunotherapy in elderly patients with hepatocellular carcinoma

Liver cancer, more specifically hepatocellular carcinoma (HCC), is a global health issue and one of the dominant causes of cancer death around the world. In the past few decades, remarkable advances have been achieved in the systemic therapy of HCC. Immune checkpoint inhibitors (ICIs) have become a therapy mainstay for advanced HCC and have shown promise in the neoadjuvant therapy before resection. Despite these significant advancements, the compositions and functions of the immune system occur various alterations with age, called "immunosenescence", which may affect the antitumor effects and safety of ICIs, thus raising concerns that immunosenescence may impair elderly patients' response to ICIs. Therefore, it is important to learn more about the immunosenescence characteristics of elderly patients. However, the real-world elderly HCC patients may be not accurately represented by the elderly patients included in the clinical trials, affecting the generalizability of the efficacy and safety profiles from the clinical trials to the real-world elderly patients. This review summarizes the characteristics of immunosenescence and its influence on HCC progression and immunotherapy efficacy as well as provides the latest progress in ICIs available for HCC and discusses their treatment efficacy and safety on elderly patients. In the future, more studies are needed to clarify the mechanisms of immunosenescence in HCC, and to find sensitive screening tools or biomarkers to identify the patients who may benefit from ICIs.

RALOX-HAIC (raltitrexed + oxaliplatin) combined with lenvatinib improves survival and safety in elderly patients with unresectable hepatocellular carcinoma

OBJECTIVE

To explore the efficacy and safety of RALOX-HAIC (raltitrexed plus oxaliplatin) combined with lenvatinib in the treatment of elderly patients with unresectable hepatocellular carcinoma (uHCC), aiming to provide a safer and more effective therapeutic strategy for this patient population.

MATERIALS AND METHODS

A retrospective analysis was conducted on the clinical data of 82 elderly patients with uHCC who received treatment in the Department of Interventional Radiology at Wuhan Union Hospital from January 2019 to December 2022. Patients were divided into two groups based on their treatment strategy: HAIC + Lenvatinib group (N = 39) and TACE group (N = 43). The primary endpoints were the objective response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS) in the two groups. The secondary endpoint was the incidence of treatment-related adverse events in both groups.

RESULTS

The ORR and DCR after treatment were higher in the HAIC + Lenvatinib group compared to the TACE group (61.5% vs. 37.2%, 82.1% vs. 58.1%, P < 0.05). The HAIC + Lenvatinib group had a longer median progression-free survival (mPFS,9.2 months vs. 4.6 months, P < 0.001) and ​median overall survival(mOS, 18.1 months vs. 10.6 months, P < 0.001) compared to the TACE group. The incidence of abdominal pain and fever was significantly higher in the TACE group than in the HAIC + Lenvatinib group (including all grades and grades 3/4, P < 0.05). The incidence of hand-foot syndrome (all grades) was higher in the HAIC + Lenvatinib group compared to the TACE group (15.4% vs. 0.0%, P = 0.009), but there was no significant difference in the incidence of grade 3/4 hand-foot syndrome between the two groups (2.6% vs. 0.0%, P = 0.476).

CONCLUSION

This study demonstrates that RALOX-HAIC combined with lenvatinib provides superior survival outcomes and tolerability compared to TACE alone ​in elderly patients (≥ 70 years) with unresectable HCC. This combination therapy may be a feasible and safe option for improving the prognosis of elderly patients with uHCC.

Prognostic Analysis of Elderly Patients with Hepatocellular Carcinoma: an Exploration and Machine Learning Model Prediction Based on Age Stratification and Surgical Approach

Purpose

As the global population ages, precise prognostic tools are needed to optimize postoperative care for elderly hepatocellular carcinoma (HCC) patients. This study established a machine learning-driven predictive model to identify key prognostic determinants and evaluate age/surgical approach impacts, overcoming limitations of traditional statistical methods.

Methods

This retrospective study included 252 postoperative HCC patients aged ≥65 years (mean age 69.0±4.3; 68.25% male). Patients were randomly divided into training (70%, n=177) and validation sets (30%, n=75). We evaluated 147 machine learning models to establish the optimal predictive model. Patients were grouped by age (>75 vs ≤75 years) and surgical approach (laparoscopic vs open).

Results

The LASSO+RSF model showed strong predictive performance with AUC values of 0.869 and 0.818 in the training and validation sets, respectively. Time-dependent AUCs for 1-, 2- and 3-year survival were 0.874, 0.903, and 0.883 in the training set, and 0.878, 0.882, and 0.915 in the validation set. Key predictors included age-adjusted Charlson index (ACCI, LASSO+RSF synergistic weight (LRSW) =0.160), microvascular invasion (0.111), tumor capsule integrity (0.034), and lymphatic invasion (0.023), while three variables (intraoperative blood loss, tumor margin, WBC) were excluded (LRSW<0.01). A web-based dynamic nomogram (https://cliniometrics.shinyapps.io/LRSF-GeroHCC/) enabled real-time risk stratification. Patients >75 years had longer length of stay (16 vs 14 days, P=0.033), higher Clavien-Dindo scores (P=0.014), higher ACCI scores (5.5 vs 4.0, P=0.002), and lower PFS (16.5 vs 24 months, P=0.041). Laparoscopic surgery was associated with longer operative time (202.5 vs 159.0min, P<0.001), shorter length of stay (14 vs 17days, P<0.001), and lower Clavien-Dindo scores (P=0.038).

Conclusion

The LASSO+RSF model provides validated tools for personalized prognosis management in elderly HCC patients, emphasizing age-adapted surgical strategies and comorbidity-focused perioperative care.

Management of hepatocellular carcinoma in elderly and adolescent/young adult populations

Hepatocellular carcinoma (HCC) presents unique challenges in both the elderly and adolescent/young adult (AYA) populations, requiring distinct management approaches. Recent epidemiological data show an increasing incidence of HCC in both age groups, with elderly cases rising significantly and AYA cases showing trends in specific regions. The clinical characteristics and treatment considerations vary substantially among these populations. Elderly patients with HCC typically present with hepatitis C virus infection, metabolic dysfunction-associated steatotic liver disease, well-differentiated tumors, and multiple comorbidities. In contrast, AYA patients with HCC often present with more aggressive tumor characteristics and predominantly with hepatitis B virus-related diseases. Treatment decisions for elderly patients with HCC require careful consideration of physiological reserves, comprehensive geriatric assessments, and potential complications. Recent studies have demonstrated that elderly patients can achieve outcomes comparable to younger patients across various treatment modalities when properly selected. While surgical outcomes are comparable to those of younger patients with proper selection, less-invasive options such as radiofrequency ablation or transarterial therapies may be more appropriate for some elderly patients. The treatment approach for AYA HCC emphasizes curative intent while considering long-term effects. AYA patients require specialized attention to their psychosocial needs, fertility preservation, and long-term health maintenance. Although data on AYA patients remain limited, they are known to have relatively favorable prognoses despite exhibiting more aggressive tumor characteristics. Management of HCC in both the elderly and AYA populations requires individualized approaches that consider age-specific factors. Both groups benefit from multidisciplinary team involvement and careful consideration of quality of life.

The Influence of Sex and Age on Survival in Patients with Hepatocellular Carcinoma

Background and Aim: Age and biological sex are risk factors for hepatocellular carcinoma (HCC) occurrence, but their impact on overall survival (OS) is a matter of debate. This study aims to investigate how sex and age at diagnosis, along with other associated factors (i.e., comorbidities, etiologies, therapy) impact OS in the HCC population. Method: Data from two HCC cohorts-a prospective registry from the University Hospital of Bern, Switzerland, and a retrospective registry from General Hospital Vienna, Austria-were combined and analyzed. Clinical and laboratory data were reviewed, and OS was compared using Kaplan-Meier curves and the log-rank test. Cox regression models with penalized splines were applied to examine how age at diagnosis influenced OS. Results: Of 1547 HCC patients, 1284 (84.1%) were male. Females were older (67 vs. 63 years, p < 0.001) and had lower rates of liver cirrhosis (p < 0.001), cardiac comorbidities (p < 0.001), and diabetes (p < 0.001). No significant difference in median OS between men and women was observed (18 months vs. 16 months, p = 0.304). Mortality risk increased with age, particularly between 60 and 70 years. However, after adjusting for treatment, the age effect became non-significant (p = 0.171). Conclusions: After controlling the model for therapy, neither age nor sex independently influenced OS in HCC patients, underscoring the impact of therapy on survival.

Discontinuation of immune checkpoint inhibitors in hepatocellular carcinoma: a retrospective cohort study

Background

The optimal timing to discontinue immune checkpoint inhibitor (ICI) therapy in hepatocellular carcinoma (HCC) patients with clinical benefits remains unclear. This study aimed to assess the outcomes of HCC patients after ICI discontinuation.

Methods

Patients with HCC were retrospectively screened and those discontinued ICI therapy in the absence of progressive disease (PD) were included. Responses at discontinuation were evaluated per response evaluation criteria in solid tumors (RECIST) version 1.1 and modified RECIST (mRECIST). Patients were classified into five subgroups according to the cause of discontinuation: complete response (CR), partial response (PR), stable disease (SD) per RESICT version 1.1, adverse event (AE), or others. Progression-free survival (PFS) and overall survival (OS) since ICI start or after ICI discontinuation were assessed.

Results

A total of 66 patients were included. The median follow-up was 29.33 months. The median PFS since ICI start was 30.83 months [95% confidence interval (CI): 24.93-36.72], and the median OS was not reached. The median PFS after discontinuation was 20.6 months (95% CI: 7.63-33.56), and the median OS after discontinuation was not reached. Univariate analysis showed that age, treatment after discontinuation, Response (RECIST version 1.1) at discontinuation and modified response (mResponse per mRECIST) at discontinuation were significantly associated with PFS after discontinuation, while age and mResponse at discontinuation were significantly associated with OS after discontinuation. Multivariate analysis further demonstrated that mResponse at discontinuation and treatment after discontinuation were independently associated with PFS after discontinuation, while age was independently associated with OS after discontinuation.

Conclusions

ICIs might be discontinued in HCC patients with a response of CR per mRECIST. Patients with a response of PR/SD per mRECIST or elder age could continue ICI therapy after achieving clinical benefits. Tyrosine kinase inhibitor (TKI) maintenance therapy might help to prevent progression after ICI discontinuation.

A Novel Nomogram to Predict Prognosis in Elderly Early-Stage Hepatocellular Carcinoma Patients After Ablation Therapy

Purpose

Hepatocellular carcinoma (HCC) is the predominant form of primary liver cancer. Early diagnosis is crucial for improving prognosis. Elderly HCC patients often have underlying liver diseases such as chronic hepatitis and cirrhosis, leading to impaired liver function and suboptimal liver reserve. Radiofrequency ablation (RFA) has rapidly become one of the most important methods for treating early-stage hepatocellular carcinoma (EHCC) due to its advantages, including minimal trauma, short operation time, less intraoperative bleeding, quick postoperative recovery, cost-effectiveness, and few postoperative-complications. However, the prognostic model for early recurrence after local ablation in elderly EHCC patients has not been widely evaluated. We have developed a prognostic model for the recurrence of local RFA in elderly EHCC patients. This is expected to provide a new early warning system for preventing early recurrence in elderly EHCC patients, prolonging patient's life, and improving overall quality of life.

Methods

In this study, we included 661 EHCC patients who underwent local ablation, dividing them into a Primary cohort and a Validation cohort in a 7:3 ratio. We characterized the cohorts and utilized the primary cohort to develop a prognostic nomogram model for recurrence after local ablation in elderly EHCC patients. Additionally, the validation cohort was used to assess the potential of the nomogram as a non-invasive biomarker for post-ablation recurrence in EHCC.

Results

The user-friendly nomogram incorporates common clinical variables including gender, BCLC stage, tumor number, tumor size, red blood cell (RBC), gamma-glutamyl transferase (GGT), and prothrombin time activity (PTA). The nomogram constructed using the identified seven variables exhibits robust discriminatory capabilities, favorable predictive performance, and noteworthy clinical utility.

Conclusion

We developed a user-friendly nomogram based on the BCLC stage classification, which may provide prognostic assessments for elderly EHCC patients at 1, 3, and 5 years post-RFA.

Oncological prognosis and morbidity of hepatectomy in elderly patients with hepatocellular carcinoma: a propensity score matching and multicentre study

PURPOSE

With increasing life expectancy, the number of elderly patients (≥ 65 years) with hepatocellular carcinoma (HCC) has steadily increased. Hepatectomy remains the first-line treatment for HCC patients. However, the prognosis of hepatectomy for elderly patients with HCC remains unclear.

METHODS

Clinical and follow-up data from 1331 HCC patients who underwent surgery between 2008 and 2020 were retrospectively retrieved from a multicentre database. Patients were divided into elderly (≥ 65 years) and non-elderly (< 65 years) groups, and PSM was used to balance differences in the baseline characteristics. The postoperative major morbidity and cancer-specific survival (CSS) of the two groups were compared and the independent factors that were associated with the two study endpoints were identified by multivariable regression analysis.

RESULTS

Of the 1331 HCC patients enrolled in this study, 363 (27.27%) were elderly, while 968 (72.73%) were not. After PSM, 334 matched samples were obtained. In the propensity score matching (PSM) cohort, a higher rate of major morbidity was found in elderly patients (P = 0.040) but the CSS was similar in the two groups (P = 0.087). Multivariate analysis revealed that elderly age was not an independent risk factor associated with high rates of major morbidity (P = 0.117) or poor CSS (P = 0.873). The 1-, 3- and 5-year CSS rates in the elderly and non-elderly groups were 91.0% versus 86.2%, 71.3% versus 68.8% and 55.9% versus 58.0%, respectively. Preoperative alpha fetoprotein (AFP) level, Child‒Pugh grade, intraoperative blood transfusion, extended hemi hepatectomy, and tumour diameter could affect the postoperative major morbidity and preoperative AFP level, cirrhosis, Child‒Pugh grade, macrovascular invasion, microvascular invasion (MVI), satellite nodules, and tumor diameter were independently and significantly associated with CSS.

CONCLUSION

Age itself had no significant effect on the prognosis of elderly patients with HCC after hepatectomy. Hepatectomy can be safely performed in elderly patients after cautious perioperative management.

Prognostic factors and predictive nomogram models for early death in elderly patients with hepatocellular carcinoma: a population-based study

Background: Owing to an aging society, there has been an observed increase in the average age of patients diagnosed with hepatocellular carcinoma (HCC). Consequently, this study is centered on identifying the prognostic factors linked with early death among this elderly demographic diagnosed with HCC. Additionally, our focus extends to developing nomograms capable of predicting such outcomes. Methods: The Surveillance, Epidemiology and End Results (SEER) database underpinned this study, showcasing participants aged 75 and above diagnosed with HCC within the timeframe from 2010 to 2015. These participants were divided randomly, at a 7:3 ratio, into training and validation cohorts. Univariable and multivariable logistic regressions were applied to the training cohort in the identification of prognostic indicators of early death, forming the basis for nomogram development. To measure the efficacy of these nomograms within both cohorts, we resorted to Receiver Operating Characteristic (ROC) curves, along with GiViTI calibration belt and Decision Curve Analysis (DCA). Results: The study involved 1,163 elderly individuals diagnosed with HCC, having reported instances of 397 all-cause early deaths and 356 HCC-specific early deaths. The sample group was divided into two cohorts: a training group consisting of 815 individuals, and a validation cohort, comprised of 348 individuals. Multifactorial analysis identified grade, T-stage, surgery, radiation, chemotherapy, bone and lung metastasis as significant predictors of mortality from all causes. Meanwhile, race, grade, T-stage, surgery, radiation, chemotherapy, and bone metastasis were revealed to be estimative factors for cancer-specific mortality. Subsequently, these factors were used to develop nomograms for prediction. GiViTI calibration belt corroborated the acceptable coherence of the nomograms, DCA confirmed their valuable clinical applicability, and ROC curves evidenced satisfactory discriminative capacity within both training and validation cohorts. Conclusion: The nomograms utilized in this study proved instrumental in detecting early death among elderly individuals afflicted with HCC. This tool could potentially assist physicians in formulating individualized treatment strategies.

A nationwide study on the current treatment status and natural prognosis of hepatocellular carcinoma in elderly

The aim of this study was to identify the treatment status and natural prognosis of hepatocellular carcinoma (HCC) patients aged 65 years or older in Korea. We analyzed 3,492 patients' data from the liver cancer stage of the Central Cancer Registry of National Cancer Center. The most common etiology of HCC was hepatitis B (32.7%), followed by hepatitis C. 2624 patients (69.2%) received first-line active treatment for HCC. The most frequently selected treatment was transarterial chemoembolization (TACE), followed by surgical resection and radiofrequency ablation (RFA). The proportion of patients receiving supportive care increased with age. Second-line treatment was performed in only 36.7% of cases, with all others choosing supportive care. Among the various treatments, liver transplantation was found to have the greatest effect in reducing the risk of death (HR [hazard ratio] 0.164, 95% CI [confidence interval] 0.061-0.444), followed by resection, RFA, radioembolization, and TACE. A similar pattern was observed when sub-analyzing the age group over 75 years old. The median survival for untreated HCC in Barcelona Clinic Liver Cancer stage 0/A/B/C/D was 3.7 years, 2.3 years, 7.9 months, 3.9 months, and 2.9 months, respectively. This study highlights the current status of elderly patients with HCC in Korea. While the proportion of patients receiving supportive care is high among the elderly, effective treatment can improve their survival rate.

Development and validation of a prediction model for the prolonged length of stay in Chinese patients with lower extremity atherosclerotic disease: a retrospective study

OBJECTIVES

This study aims to develop and internally validate a prediction model, which takes account of multivariable and comprehensive factors to predict the prolonged length of stay (LOS) in patients with lower extremity atherosclerotic disease (LEAD).

DESIGN

This is a retrospective study.

SETTING

China.

PARTICIPANTS, PRIMARY AND SECONDARY OUTCOMES

Data of 1694 patients with LEAD from a retrospective cohort study between January 2014 and November 2021 were analysed. We selected nine variables and created the prediction model using the least absolute shrinkage and selection operator (LASSO) regression model after dividing the dataset into training and test sets in a 7:3 ratio. Prediction model performance was evaluated by calibration, discrimination and Hosmer-Lemeshow test. The effectiveness of clinical utility was estimated using decision curve analysis.

RESULTS

LASSO regression analysis identified age, gender, systolic blood pressure, Fontaine classification, lesion site, surgery, C reactive protein, prothrombin time international normalised ratio and fibrinogen as significant predictors for predicting prolonged LOS in patients with LEAD. In the training set, the prediction model showed good discrimination using a 500-bootstrap analysis and good calibration with an area under the receiver operating characteristic of 0.750. The Hosmer-Lemeshow goodness of fit test for the training set had a p value of 0.354. The decision curve analysis showed that using the prediction model both in training and tests contributes to clinical value.

CONCLUSION

Our prediction model is a valuable tool using easily and routinely obtained clinical variables that could be used to predict prolonged LOS in patients with LEAD and help to better manage these patients in routine clinical practice.

AFP and CA-125 as an accurate risk factor to predict eye metastasis in hypertension patients with liver carcinoma: A STROBE-compliant article

Purpose: In this study, we analyzed the differences between hypertension patients with ocular metastasis of liver cancer and those with metastases to other sites, the correlation between history of HBV and liver cancer metastasis, and independent risk factors for ocular metastasis.

Methods: We used treatment records from 488 patients with metastases of primary liver cancer from August 2001 to May 2015, divided into two groups based on metastatic sites: OM (ocular metastasis) and NOM (non-ocular, other sites of metastasis) groups. The Student’s t-test and Chi-square test were used to assess the significance of differences between the groups and define the relationship between history of HBV and ocular metastasis of liver cancer. Binary logistic regression analysis was used to identify indicators of ocular metastasis of liver cancer and receiver operating curve (ROC) analyses to estimate their diagnostic value.

Results: No significant differences in sex, age, tumor stage, pathological type, or treatment were identified between the OM and NOM groups, while the prevalence of HBV was higher in the former than that in latter. Binary logistic regression demonstrated that AFP and CA-125 were independent indicators of liver metastasis (both p < 0.001). ROC curve analyses generated cut-off values for AFP and CA-125 of 957.2 ng/ml and 114.25 U/ml, respectively, with corresponding AUC values of 0.739 and 0.810. The specificity of the combination of AFP and CA-125 was higher than either factor separately.

Discussion: To explore the diagnostic value of AFP and CA125 in predicting the development of ocular metastases of hypertensive patients with liver cancer, which will help us to diagnose the occurrence and development of the disease more accurately and make the best clinical diagnosis and treatment measures.

Outcomes of Geriatric Patients with Hepatocellular Carcinoma

Background: The treatment modalities and outcomes of geriatric patients with hepatocellular carcinoma (HCC) remain controversial. This retrospective observational cohort study compared the outcomes of HCC between geriatric and younger patients. Methods: The medical records of patients with HCC managed between January 2001 and December 2017 were retrieved from the Chang Gung Memorial Hospital Research Database. Patients were stratified by age into two groups: a geriatric group (65−75 years) and a younger group (<65 years). The two groups were matched through 1:2 propensity score matching (PSM) according to sex, cardiovascular disease, cerebrovascular attack, diabetes mellitus, cirrhosis, hepatitis, and hypertension. Results: Of the 11,033 patients with HCC, 2147 patients aged 65−75 years and 4294 patients aged <65 years were identified after 1:2 PSM. The Kaplan−Meier model revealed that the HCC outcomes in patients older than 65 years were not significantly different after 3 years (p = 0.060). Consistent results were also obtained when the laboratory data associated with HCC incidence were included in the Fine−Gray competing risk model after 1:2 PSM (p = 0.1695). The major risk factors for HCC survival were systemic immune-inflammation index (SII) ≥ 610 × 109 cells/L, advanced tumor stage, and model for end-stage liver disease (MELD) score, etc. Conclusion: Age was not an independent factor for mortality in patients with HCC in the first 3 years. Geriatric patients with HCC should be as aggressively managed as younger patients.

Effect of age on the short- and long-term outcomes of patients undergoing curative liver resection for HCC

BACKGROUND

Few studies have evaluated the outcomes of curative liver resection (LR) in octogenarian patients, analysed cancer-specific survival (CSS) with HCC-related death or explored the age-varying effect of HCC-related death in elderly patients undergoing LR. We aim to determine the effect of age on the short and long-term outcomes of LR for HCC.

METHODOLOGY

Between 2000 and 2018, 1,092 patients with primary HCC who underwent LR with curative intent were retrospectively reviewed. The log-rank test and Gray's test were used to assess the equality of survivor functions and competing risk-adjusted cumulative incidence functions between patients in the three age categories respectively. Regression adjustment was used to control for confounding bias via a Principal Component Analysis. Quantile, Firth logistic, Cox, and Fine-Gray competing risk regression were used to analyse continuous, binary, time-to-event, and cause-specific survival respectively. Restricted cubic splines were used to illustrate the dose-effect relationship between age and patient outcomes.

RESULTS

The study comprised of 764 young patients (<70 years), 278 septuagenarians (70-79 years old) and 50 octogenarians (≥80 years). Compared to young patients, octogenarians had significantly lower 5-year OS(62.1% vs 37.7%, p < 0.001). However, there was no significant difference in 1-year RFS(73.1% vs 67.0%, p = 0.774) or 5-year CSS (5.4% vs 15.2%, p = 0.674). Every 10-year increase in age was significantly associated with an increase length of stay (p < 0.001), postoperative complications (p = 0.004) and poorer OS(p = 0.018) but not significantly associated with major complications (p = 0.279), CSS(p = 0.338) or RFS(p = 0.941).

CONCLUSION

Age by itself was associated with OS after LR for HCC but was not a significant risk factor for HCC-related death.

Equal Efficacy and Safety Profile in Elderly Patients with Hepatocellular Carcinoma Receiving Palliative Treatment

Palliative treatment of elderly patients with hepatocellular carcinoma (HCC) is often challenging due to comorbidities or frailty, and data about the outcome and overall survival (OS) in these patients are limited. This was a retrospective single centre study. Patients were grouped according to their age as young (<60 years; YP), intermediate (60-70 years; IP) or elderly (>70 years; EP). Administration of chemotherapy or transarterial chemoembolization (TACE) was defined as palliative treatment. Therapy-related adverse events (AE) were assessed via CTCAE 5.0. Out of 656 patients analyzed, n = 359 received palliative treatment: YP: n = 90; IP: n = 127 and EP: n = 142. The median OS (months) in patients receiving TACE (n = 254) was 17 vs. 18 vs. 20 months for YP, IP, and EP, respectively (p = 0.44) and 15 vs. 16 vs. 17 months (p = 0.56), respectively, in patients receiving chemotherapy (n = 105). AEs differed non-significantly between the subgroups. Multivariate analysis revealed impaired liver function and advanced tumor stage as significant factors for impaired OS. In this study, the mOS and rate of AEs were equal between elderly and younger HCC patients receiving palliative treatment. Therefore, we propose regular palliative treatment stratification in spite of the high age of patients.

A Web-Based Prediction Model for Cancer-Specific Survival of Elderly Patients With Early Hepatocellular Carcinoma: A Study Based on SEER Database

Background: Primary liver cancer is a common malignant tumor primarily represented by hepatocellular carcinoma (HCC). The number of elderly patients with early HCC is increasing, and older age is related to a worse prognosis. However, an accurate predictive model for the prognosis of these patients is still lacking.

Methods: Data of eligible elderly patients with early HCC in Surveillance, Epidemiology, and End Results database from 2010 to 2016 were downloaded. Patients from 2010 to 2015 were randomly assigned to the training cohort (n = 1093) and validation cohort (n = 461). Patients' data in 2016 (n = 431) was used for external validation. Independent prognostic factors were obtained using univariate and multivariate analyses. Based on these factors, a cancer-specific survival (CSS) nomogram was constructed. The predictive performance and clinical practicability of our nomogram were validated. According to the risk scores of our nomogram, patients were divided into low-, intermediate-, and high-risk groups. A survival analysis was performed using Kaplan–Meier curves and log-rank tests.

Results: Age, race, T stage, histological grade, surgery, radiotherapy, and chemotherapy were independent predictors for CSS and thus were included in our nomogram. In the training cohort and validation cohort, the concordance indices (C-indices) of our nomogram were 0.739 (95% CI: 0.714–0.764) and 0.756 (95% CI: 0.719–0.793), respectively. The 1-, 3-, and 5-year areas under receiver operating characteristic curves (AUCs) showed similar results. Calibration curves revealed high consistency between observations and predictions. In external validation cohort, C-index (0.802, 95%CI: 0.778–0.826) and calibration curves also revealed high consistency between observations and predictions. Compared with the TNM stage, nomogram-related decision curve analysis (DCA) curves indicated better clinical practicability. Kaplan–Meier curves revealed that CSS significantly differed among the three different risk groups. In addition, an online prediction tool for CSS was developed.

Conclusions: A web-based prediction model for CSS of elderly patients with early HCC was constructed and validated, and it may be helpful for the prognostic evaluation, therapeutic strategy selection, and follow-up management of these patients.

Immunotherapy in older patients with hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is one of the most common types of cancer globally and is currently the third leading cause of cancer-related deaths. Recently, immunotherapy using immune checkpoint inhibitors (ICIs) has been shown with encouraging anticancer activity and safety in clinical trials. To reverse the phenomenon of tumours evading immune response, ICIs can be used to stimulate the natural antitumour potential of cancer cells by blocking the relevant checkpoints to activate T cells. However, the components and functions of the immune system may undergo a series of changes with ageing, known as 'immunosenescence,' potentially affecting the antitumour effect and safety of immunotherapy. In the current phase III clinical trials of ICIs including nivolumab, pembrolizumab and atezolizumab, the proportion of patients with HCC older than 65 years in CheckMate 459, KEYNOTE-240 and IMbrave150 is 51%, 58% and 50%, respectively, which is less than 70%-73% of epidemiological investigation. Therefore, the elderly population recruited in clinical trials may not accurately represent the real-world elderly patients with HCC, which affects the extrapolation of the efficacy and safety profile obtained in clinical trials to the elderly population in the real world. This review provides the latest advances in ICIs immuno-treatment available for HCC and relevant information about their therapeutic effects and safety on elderly patients. We discuss the benefits of ICIs for older HCC patients, and relevant recommendations about conducting further clinical trials are proposed for more complete answers to this clinical issue.

Hospital Frailty Risk Score Is Independently Associated with Mortality and Encephalopathy in Hospitalized Patients with Hepatocellular Carcinoma

Frailty represents a state of vulnerability to multiple internal physiologic factors, as well as external pressures, and has been associated with clinical outcomes. We aim to understand the impact of frailty on patients admitted with hepatocellular carcinoma (HCC) by using the validated Hospital Frailty Risk Score, which is implemented in several hospitals worldwide. We conducted a nation-wide retrospective cohort study to determine the effect of frailty on the risk of in-patient mortality, hepatic encephalopathy, length of stay and cost. Frailty was associated with a 4.5-fold increased risk of mortality and a 2.3-fold increased risk of hepatic encephalopathy. Adjusted Cox regression showed that frailty was correlated with increased risk of in-patient mortality (hazard ratio: 2.3, 95% CI 1.9-2.8, p < 0.001). Frail HCC patients had longer hospital stay (median 5 days) vs. non-frail HCC patients (median 3 days). Additionally, frail patients had higher total costs of hospitalization ($40,875) compared with non-frail patients ($31,667). Frailty is an independent predictor of hepatic encephalopathy and in-patient mortality. Frailty is a surrogate marker of hospital length of stay and cost.

Reducing the heterogeneity in hepatocellular carcinoma. A cluster analysis based on clinical variables in patients treated at a quaternary care hospital

INTRODUCTION AND AIMS

Even though the term hepatocellular carcinoma designates the most common type of primary liver cancer, the disease has a high level of heterogeneity due to its etiology, geographic variation, behavior, and association with specific genetic alterations. The aim of the present study was to establish, through a cluster analysis, the clinical characteristics that enable homogeneous conglomerates to be defined.

MATERIALS AND METHODS

An exploratory cluster analysis was developed utilizing the K-means method for sub-classifying 119 cases of patients with hepatocellular carcinoma. Sixty-two of those patients met the inclusion criteria, as well as none of the exclusion criteria. For the cluster analysis, an n-dimensional space was defined, in which n was equal to the number of variables included in the study (n = 17). The spatial coordinates corresponded to any possible magnitude between the minimum and maximum values of the variables analyzed (age, sex, tumor volume, AFP, AST, DB, Alb, Na, INR, Cr, HBV, HCV, OH, NASH, cirrhosis, multiple tumors, and neotumor).

RESULTS

Four patterns with homogeneous clinical characteristics were identified, in which age at presentation, history of hepatitis B virus infection, altered liver profile with cholestatic dominance, and low albumin levels were associated with an apparently worse outcome.

CONCLUSIONS

How heterogeneity in hepatocellular carcinoma could be reduced was shown through utilizing an unsupervised learning method to define specific subgroups, in whom known pathophysiologic mechanisms could better explain tumor behavior and define the determining prognostic factors related to the subgroups.

Resubclassification and clinical management for Barcelona Clinic Liver Cancer Stage C hepatocellular carcinoma

BACKGROUND

Patients with Barcelona Clinic Liver Cancer Stage C (BCLC-C) hepatocellular carcinoma (HCC) can be markedly heterogeneous with varying prognosis. This study aims to establish a new subclassification system for BCLC-C HCC to better predict overall survival (OS) and to tailor therapy.

METHODS

We retrospectively studied 1856 BCLC-C HCC patients between 2006 and 2017 from E-Da Hospital, Taiwan (n = 622, training cohort), Kaohsiung Medical University Hospital, Taiwan (n = 774, Taiwan validation cohort), and Stanford University Medical Center and Mayo Clinic (United States), Hanyang University Hospital (South Korea), and Ogaki Municipal Hospital (Japan) to make up the international validation cohort (n = 460).

RESULTS

In the training cohort, significant factors associated with OS were largest tumor size ≥ 10 cm, extrahepatic spread, macrovascular invasion, and Child-Pugh class, which provided the basis, together with aged ≥ 75 years, for the substaging, through C0 to C4, of BCLC-C HCC patients. The median OS for substages C0, C1, C2, C3, and C4 were 43.8 months (95% confidence interval [CI] 32.2-53.7), 20.6 months (CI 14.1-25.9), 11.5 months (CI 8.02-14.1), 5.7 months (CI 4.02-5.98), and 3.2 months (CI 2.41-3.59), respectively, (p < 0.05). OS remained distinct among the proposed substages in the Taiwan validation cohort as well as the international validation cohort. The distinction between the substages persisted in subgroup analysis by substage combined with treatment modality. In substage C0-C3, patients receiving HCC curative therapy had a significantly better median OS than those receiving sorafenib or palliative therapy.

CONCLUSION

Our new substaging system provides more precise prognosis to better tailor therapy for BCLC-C HCC patients.

Clinical Features and Overall Survival of Females with Hepatocellular Carcinoma: A Retrospective Study and Review of the Literature in the Association of Southeast Asian Nations

Introduction

Hepatocellular carcinoma (HCC) causes more than 200,000 women deaths annually. This study aimed to investigate the clinical features, provide prognostic factors for female patients with HCC, and performed a literature review on them in the Association of Southeast Asian Nations (ASEAN).

Materials and Methods

We conducted a retrospective cohort study of female patients with HCC at Thammasat University Hospital, Thailand between January 2009 and January 2019. Furthermore, important aspects of female patients with HCC in the ASEAN published in PubMed and Scopus up to October 2020 were extensively reviewed.

Results

A total of 187 female patients with HCC were included (mean age 65.7±11.9 years). Elderly females were diagnosed with HCC at a more advanced stage than younger individuals (37.0% vs 23.2%, p=0.049, OR 1.94, 95% CI 1.00-3.78) and the younger group had a significantly higher overall 2-year survival rate than the elderly group (65.0% vs 45.5%, p=0.03, OR 2.23, 95% CI 1.09-4.57). Abdominal pain (HR 9.89, 95% CI 2.85-34.38, p<0.001), ascites at presentation (HR 2.77, 95% CI 1.11-6.92, p=0.03), ruptured hepatoma (HR 14.68, 95% CI 12.60-83.09, p=0.002), advanced-stage HCC (HR 9.74, 95% CI 1.89-50.26; p=0.007), and serum hypoalbuminemia (HR 4.67, 95% CI 1.62-13.50, p=0.004) were significantly associated with poor survival rate. From the ASEAN, a total of 543 females HCC patients from 6 studies were extensively reviewed. Chronic hepatitis B infection was among the pre-existing liver disease leading to HCC in ASEAN. HCC in females of the ASEAN occurred most often at an advanced age and had a grave prognosis.

Conclusion

HCC affects a large number of females, especially in Thailand and the ASEAN, is diagnosed at an advanced stage and had a grave prognosis. Abdominal pain, ascites, ruptured HCC, advanced-stage HCC, and serum hypoalbuminemia are associated with poor prognosis. Early detection of HCC and prompt treatment in patients at risk could result in better survival outcomes.

Nomograms to predict survival outcomes after microwave ablation in elderly patients (>65 years old) with early-stage hepatocellular carcinoma

Objectives: To develop and validate the nomograms to predict survival outcomes after microwave ablation (MWA) in elderly patients(>65 years old) with early-stage hepatocellular carcinoma (EHCC).Methods: This retrospective study was approved by the institutional review board. A total of 265 EHCC patients (76 females, 189 males; average age 71.4 years ± 5.4 [standard deviation]) with 345 nodules subsequently underwent MWA from April 2006 to October 2019. Baseline characteristics were collected to identify the risk factors for the determination of survival outcomes after MWA. The nomograms were based on prognostic factors for overall survival (OS) and recurrence-free survival (RFS) from the multivariate Cox proportional hazards model and validated in external cohorts from another two institutions (n = 130). The nomograms were assessed for their predictive accuracy using Harrell's concordance index (C-index).Results: After a median follow-up time of 28.6 months, 29.8% (79/265) of the patients died, and 54.3% (144/265) of the patients experienced recurrence in the training set. The OS nomogram was developed based on the hepatitis B virus (HBV) presence, α-fetoprotein (AFP), and albumin, with a C-index of 0.757 (95% confidence interval [CI]: 0.645, 0.789).The scores of the nomogram ranged from 0 to 24. The RFS nomogram was developed based on tumor number, abutting major vessels and platelets, with a C-index of 0.733 (CI: 0.672, 0.774). The likelihood of 3- and 5-year OS and RFS were consistent between clinical observations and nomogram predictions in external cohorts.Conclusions: The nomogram models can be useful in determining the risk of OS and RFS in elderly patients with EHCC after MWA, which can guide individual patient management.Key pointsMWA is an effective and feasible treatment for elderly patients with EHCC and can improve survival outcomes.A calibrated and objective nomogram model for the prediction of survival outcomes in elderly patients (>65 years old) may guide patient selection and MWA treatment.Older age was not deemed to be a risk factor for survival outcomes when the elderly patients with EHCC underwent MWA.

Reducing the heterogeneity in hepatocellular carcinoma. A cluster analysis based on clinical variables in patients treated at a quaternary care hospital

INTRODUCTION AND OBJECTIVE

Even though the term hepatocellular carcinoma designates the most common type of primary liver cancer, the disease has a high level of heterogeneity due to its etiology, geographic variation, behavior, and association with specific genetic alterations. The aim of the present study was to establish, through a cluster analysis, the clinical characteristics that enable homogeneous conglomerates to be defined.

MATERIALS AND METHODS

An exploratory cluster analysis was developed utilizing the K-means method for sub-classifying 119 cases of patients with hepatocellular carcinoma. Sixty-two of those patients met the inclusion criteria, as well as none of the exclusion criteria. For the cluster analysis, an n-dimensional space was defined, in which n was equal to the number of variables included in the study (n = 17). The spatial coordinates corresponded to any possible magnitude between the minimum and maximum values of the variables analyzed (age, sex, tumor volume, AFP, AST, DB, Alb, Na, INR, Cr, HBV, HCV, OH, NASH, cirrhosis, multiple tumors, and neotumor).

RESULTS

Four patterns with homogeneous clinical characteristics were identified, in which age at presentation, history of hepatitis B virus infection, altered liver profile with cholestatic dominance, and low albumin levels were associated with an apparently worse outcome.

CONCLUSION

How heterogeneity in hepatocellular carcinoma could be reduced was shown through utilizing an unsupervised learning method to define specific subgroups, in whom known pathophysiologic mechanisms could better explain tumor behavior and define the determining prognostic factors related to the subgroups.

Hepatocellular carcinoma in old age: are there any benefits of liver resection in old age?

Purpose

Elderly individuals have comorbidities that can adversely affect surgical outcomes. Some studies reported that elderly patients with hepatocellular carcinoma (HCC) have higher liver- and non-liver-related deaths. Therefore, palliative treatments are preferred in these patients. We compared surgical treatment outcomes between young and old age groups.

Methods

In total, 233 liver resections were performed in patients with HCC from March 2012 to December 2018. We retrospectively reviewed medical records. The old age group was defined as patients aged more than 70 years. We compared perioperative characteristics and surgical outcomes and analyzed the prognostic factors for disease-free survival (DFS) and overall survival (OS) rates.

Results

The young and old age group included 184 and 49 patients, respectively. Preoperative characteristics were similar. Major liver resection rate was similar (young age group, 26.1% vs. old age group, 20.4%), but the operation time was a little bit shorter in old age group. Major postoperative complications were 23 (12.5%) and 9 (18.4%) in the young and old age group (P = 0.351). Median non-liver-related overall survival were 80 and 76 months (P = 0.889) and liver-related OS were 76 and 76 months (P = 0.514) in the young and old age groups, respectively. Age was not an independent risk factor for DFS and OS.

Conclusion

Elderly patients showed similar non-liver- and liver-related OS rates as young patients after liver resection. Postoperative complications were also similar. If elderly patients are well selected, they can receive curative treatment and show good surgical outcomes.

Prognoses, outcomes, and clinicopathological characteristics of very elderly patients with hepatocellular carcinoma who underwent hepatectomy

Objectives

The aim was to evaluate the prognostic factors, clinicopathological characteristics, and surgical outcomes after hepatectomy in very elderly patients with hepatocellular carcinoma (HCC).

Methods

We analyzed 796 patients with HCC from 2000 to 2017. Patients aged 80 years or older were classified into the very elderly group (group VE; n = 49); patients younger than 80 years old and aged 65 years or older were classified into the elderly group (group E; n = 363), and patients younger than 65 years old were classified into the young group (group Y; n = 384). We investigated the prognoses, clinicopathological characteristics, and surgical outcomes after hepatectomy.

Results

The number of surgical procedures and outcomes, including morbidities, was not significantly different. Groups VE, E, and Y showed similar prognoses in terms of both survival and recurrence. In group VE, prothrombin activity (PA) < 80% and PIVKA-II ≥ 400 mAU/ml were unfavorable factors for survival, and PIVKA-II ≥ 400 mAU/ml and the presence of portal venous invasion (PVI), hepatic venous invasion, and fibrosis were unfavorable factors for recurrence. In group E, ChE < 180 IU/l, AFP ≥ 20 ng/ml, tumor size ≥ 10 cm, and the presence of multiple tumors, PVI, and hepatic venous invasion (HVI) were unfavorable factors for survival, and ChE < 180 IU/l, tumor size ≥ 10 cm, and the presence of multiple tumors, PVI, and HVI were unfavorable factors for recurrence. In group Y, AFP ≥ 20 ng/ml, the presence of multiple tumors, poor differentiation, PVI, HVI, and blood loss ≥ 400 ml were unfavorable factors for survival, and PA < 80%, albumin < 3.5 g/dl, AFP ≥ 20 ng/ml, tumor size ≥ 10 cm, and the presence of multiple tumors, poor differentiation, and PVI were unfavorable factors for recurrence.

Conclusions

Tumor factors might have limited influence on the prognosis of very elderly patients, and liver function reserve might be important for the long-term survival of very elderly patients. Hepatectomy can be performed safely, even in very elderly patients. Hepatectomy should not be avoided in very elderly patients with HCC if patients have a good general status because these patients have the same prognoses as nonelderly individuals.

Adjuvant transarterial chemoembolization for patients with hepatocellular carcinoma after radical hepatectomy: a real world study

Objective: To investigate the clinical value of the adjuvant transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) after radical resection, and identify the potential beneficiaries.Methods: Patients were identified through the primary liver cancer big data (PLCBD) between 2012 and 2015. Overall survival (OS) between adjuvant TACE group and non-TACE was evaluated by Kaplan-Meier before and after propensity scoring match (PSM). Subgroup analysis was conducted stratified by risk factors.Results: A total of 2066 HCC patients receiving radical resection were identified. Patients with multiple tumors, tumor diameter >5 cm, satellite, and advanced stage were more likely to accept adjuvant TACE. Before PSM, the 1-, 3-, and 5-year OS rates in the TACE group and non-TACE group were 89%, 58%, 17%, and 88%, 53%, 13% (p = .43), respectively. While, the corresponding rates were 89%, 58%, 17%, and 86%, 49%, 11%, (p = .038), respectively after 1:1 PSM. In addition, patients were found to significantly benefit from adjuvant TACE if they had age ≥50 years, no cirrhosis, AFP ≤ 200 ng/ml, surgical margin <1 cm, tumor diameter >5 cm, no capsule, no satellite, or CN stage Ib/IIa (all p < .05), but patients with age < 50 years, tumor size ≤5 cm, or CN stage Ia were found to significantly benefit from radical resection in DFS (all p < .05).Conclusion: Currently, we concluded that not all of patients with HCC would benefit from adjuvant TACE. Patients with age ≥50 years, tumor size >5 cm, or CN stage Ib/IIa were strongly recommended to receive adjuvant TACE.

Outcome of a second hepatectomy in octogenarians with hepatocellular carcinoma recurrence: single centre's experience

BACKGROUND

Physicians rarely select surgery a second time as the treatment for octogenarians with hepatocellular carcinoma (HCC) recurrence.

METHODS

We encountered eight male and three female octogenarians underwent surgery a second time as the treatment for HCC recurrence (octo group). We studied these cases clinically and compared them with 25 younger people underwent surgery a second time (young group). All patients of octo group have resectable HCC according to the Japanese guideline, that is HCC patients with Child-Pugh status A or B and who have solitary or only a few HCC nodules, in addition, no serious comorbidities, no serious dementia, a performance status of 0-1 and the will to receive hepatectomy.

RESULTS

The average maximum tumour size at the first hepatectomy was significantly larger than that at the second hepatectomy (P < 0.05). The extent of the first hepatectomy was significantly greater than that of the second one (P < 0.05). There were no mortalities at either hepatectomy. The morbidities of the first and the second hepatectomies were 9.1% and 18.2%, respectively. All complications were bile leakage. Furthermore, there were no significant differences in the clinical features, including the prognosis, between the octo and young groups.

CONCLUSION

Selected octogenarians who received a second hepatectomy showed a relatively good post-operative course after the first and second hepatectomies. Repeated hepatectomy for octogenarians seems to have same positive influence on the prognosis in comparison to the young group. But on the data analysed, we have not shown repeated hepatectomy is superior to non-surgical treatments.

Effective therapeutic options for elderly patients with hepatocellular carcinoma: A nationwide cohort study

We evaluated the post-treatment overall survival (OS) of elderly hepatocellular carcinoma (HCC) patients.The archived records of 10,578 HCC patients registered at the Korean Central Cancer Registry from 2008 through 2014 were retrospectively analyzed. In this registry, we selected Barcelona Clinic Liver Cancer (BCLC) 0, A, or B staged HCC patients (n = 4744) treated by surgical resection (SR), local ablation therapy (LAT), or locoregional therapy (LRT). OSs in nonelderly (<70 years) and elderly (≥70 years) patients were compared after propensity score matching (PSM).In BCLC 0-A staged HCC, the cumulative OS rates of elderly patients were poorer than those of nonelderly patients after PSM (P < .001), but not in those with BCLC stage B (P > .05). In BCLC 0-A staged elderly patients, OS after SR was significantly better than after LAT (P = .005) or LRT (P < .001). In BCLC B staged elderly patients, SR achieved better OS than LRT (P = .006). Multivariable analysis showed that LAT (hazard ratio [HR] 1.52, P = .048) or LRT (HR, 2.01, P < .001) as compared with SR, and large (>3 cm) tumor size (HR1.49, P = .018) were poor predictors of OS for elderly patients with BCLC stage 0-A, and that LRT (HR, 2.64, P = .042) was a poor predictor for those with BCLC stage B.SR provided a better OS rate than LAT or LRT in elderly HCC patients with BCLC stage 0-A, than LRT in those with BCLC stage B. SR should be considered the first therapeutic option even in elderly HCC patients with these stages.

Liver-related events and mortality among elderly patients with advanced chronic hepatitis C treated with direct-acting antivirals

Background

Direct-acting antivirals (DAAs) are effective in patients aged ≥65 years. However, little is known about the effects of DAAs on survival, liver decompensation and development of hepatocellular carcinoma (HCC).

Objective

To compare the incidence of liver-related events and mortality between patients aged ≥65 and <65 years.

Methods

Prospective study comparing patients aged ≥65 and <65 years treated with DAAs. The incidence of liver-related events and mortality, and HCC was compared between age groups.

Results

Five hundred patients (120 aged ≥65 and 380 aged <65 years) were included. The incidence of liver-related events was 2.62 per 100 patient-years (py) in older and 1.41/100 py in younger patients. All-cause mortality was 3.89 and 1.27/100 py in older and younger patients, respectively. The respective liver-related mortality rates were 1.12 and 0.31/100 py. In patients with cirrhosis (stage F4), all-cause mortality (P = 0.283) and liver-related mortality (P = 0.254) did not differ between groups. All five liver-related deaths were related to multifocal HCC. The incidence of HCC was 1.91 and 1.43 per 100 py in the older and younger groups, respectively (P = 0.747). The diagnosis of HCC was 8 months after the end of treatment.

Conclusions

The incidence of liver-related events and liver-related mortality was low in older people treated with DAAs and was similar to that in younger patients. The extra mortality in people aged ≥65 years treated with DAAs seems to be secondary to non-liver-related causes. These results support the utilization of DAAs in patients aged ≥65 years.

Assessing the characteristics and feasibility of preventing early mortality in patients with hepatocellular carcinoma

BACKGROUND/AIMS

To determine strategies to prevent early death (ED) and improve the prognosis of patients with advanced hepatocellular carcinoma (HCC).

MATERIALS AND METHODS

Patients who were diagnosed with HCC from January 2012 to June 2017 were considered for the study. Those who survived for ≤6 months from the date of diagnosis were classified into the ED group (n=21) and those who survived for ≥12 months from the date of diagnosis were classified into the non-ED group (n=88).

RESULTS

There were significant differences between the ED and non-ED groups in the following conditions: when the patient age was ≥80 years (38.1% vs. 14.8% patients); maximum nodule size was >3 cm (90.5% vs. 27.3%); Child-Pugh class C liver disease was seen (66.7% vs. 26.1%); tumor-node-metastasis (TNM) Stage III-IV tumor was present (85.7% vs. 21.6%); BCLC stage C/D of liver cancer was seen (81.0% vs. 21.6%); JIS score was ≥4 (52.4% vs. 3.4%); serum creatinine level was ≥1.0 mg/dL (52.4% vs. 22.7%); and there was absence of aggressive treatments such as hepatic resection, radiofrequency ablation, transarterial chemoembolization, and chemotherapy (66.7% vs. 4.5%). Logistic regression analysis identified maximum nodule size of >3 cm (p=0.005, OR=58.7, 95% CI=3.43-1003.9), JIS score of ≥4 (p=0.021, OR=12.0, 95% CI=1.44-100.1), and absence of aggressive treatments (p=0.006, OR=24.7, 95% CI=2.47-247.2) as predictive factors for ED. The presence of aggressive treatments significantly improved the 12-month survival rate of advanced HCC patients with BCLC stage C/D (presence vs. absence: 78.3% vs. 7.4%), a maximum nodule size of >3 cm (76.7% vs. 7.7%), and a JIS score of ≥4 (60.0% vs. 0%).

CONCLUSION

Although delayed detection of HCC strongly increased the onset ED, the aggressiveness of HCC treatment is not readily downgraded, and the most aggressive treatment possible should be considered to prevent ED in patients with advanced HCC.

Systemic Treatment of Advanced Hepatocellular Carcinoma in Older Adults

Over the past 30 years, the incidence in of hepatocellular carcinoma (HCC) in the United States has tripled, largely due to untreated chronic Hepatitis C virus, alcoholic hepatitis, and non-alcoholic steatohepatitis (NASH). Additionally, the incidence of HCC among South Texas Hispanics is higher than elsewhere in the United States. The median age of HCC is 62 years in United States and 67 years in South Texas, with over 30% being 70 years of age or older. However, there is limited data on how to treat older adults with advanced HCC. In this review, we will discuss treatment options for older adults with advanced HCC, further emphasizing the need for prospective studies in this population.

Multiple Antigen Stimulating Cellular Therapy (MASCT) For Hepatocellular Carcinoma After Curative Treatment: A Retrospective Study

Background & Aims: The prognosis of hepatocellular carcinoma (HCC) remains poor and available treatment options are limited. This retrospective study evaluated the efficacy of Multiple Antigen Stimulating Cell Therapy (MASCT) as an adjuvant therapy for the treatment of HCC after curative treatment.

Methods: Patients who underwent HCC curative treatments were classified into two groups: the MASCT group, in which patients received MASCT treatment after curative treatment (n = 47), and the control group, in which patients did not receive any treatment after curative treatment (n = 99). Patients who received ≥ 5 courses of MASCT treatment before recurrence or death (n = 26) were further stratified into a subgroup (multiple-course MASCT group) for analysis. The primary endpoint was overall survival (OS). The secondary endpoints were disease-free survival (DFS) and safety.

Results: Kaplan-Meier analysis showed no statistically significant difference in OS between the MASCT group and the control group (P = 0.132), nor in DFS (P = 0.310) (median: 36.17 vs. 24.27 months). However, when comparing the multiple-course MASCT treated group to the control group, Kaplan-Meier analysis showed a significant difference in OS (P = 0.011), but not in DFS (P = 0.104) (median: 47.10 vs. 24.27 months). The overall incidences of treatment-related adverse events in the MASCT group and control group were 14.89% (7/47) and 19.19% (19/99), respectively. No MASCT treatment-related serious adverse events were reported.

Conclusions: Although the MASCT group was not associated with significantly longer OS or DFS, the multiple-course MASCT group showed significantly improved overall survival after curative treatment, and the treatment procedures were well-tolerated. Multiple-course MASCT may therefore provide another choice for patients with HCC after curative treatment.

Serum Iron Levels Decreased in Patients with HBV-Related Hepatocellular Carcinoma, as a Risk Factor for the Prognosis of HBV-Related HCC

Background: Hepatocellular carcinoma (HCC) is common and the second leading causes of cancer-related deaths. HCC usually occurs on the basis of chronic liver diseases. At present, the study of iron metabolism in chronic liver diseases was limited to chronic HCV infection, nonalcoholic fatty liver disease, and alcoholic liver disease. This study aimed to investigate the effect of serum iron levels on the progression of chronic HBV infection and the relationship with the prognosis of HBV-related HCC. Methods: A respective study involving 277 healthy individuals as controls (HC), 295 patients with chronic hepatitis B (CHB), 224 patients with HBV-related liver cirrhosis (HBV-related LC), and 586 patients with HBV- related HCC were enrolled in this study. Hematological parameters, HBVDNA and liver biochemistry were analyzed. Child-Pugh grade and BCLC stage of the HBV-related HCC patients were calculated. Results: The serum iron levels were lowest in the HBV- related HCC group as compared with HC, CHB, and HBV-related LC groups (35.07 ± 6.97, 27.37 ± 10.26, 24.53 ± 10.36 vs. 17.90 ± 0.14, P < 0.001). Strikingly, serum iron levels were lowest in HBV- related HCC patients with tumor size more than 10 cm as compared with HBV- related HCC patients with tumor size smaller than 3, 3-5, and 5-10 cm by subgroup analysis (22.12 ± 0.94, 21.44 ± 1.41, 15.65 ± 0.98 vs. 13.36 ± 1.15, P < 0.001). Serum iron levels significantly decreased with worsening Child-Pugh grades and BCLC stages in HBV-related HCC group. In addition, serum iron levels was positively correlated with Retinol-Binding Protein, total bile acid, hemoglobin, and lymphocyte and negatively correlated with white blood cell (WBC) and platelet in HBV- related HCC group. ROC curve analysis showed serum iron levels at 15.1 μmol/L as the optimal cut-off point for determining the survival of HBV-related HCC. By the Cox regression model analysis, serum iron levels <15.1 μmol/l together with higher AFP levels, worse BCLC stages, and larger tumor size showed higher mortality of HBV-related HCC patients (hazard ratio = 2.280, 95% confidence interval, 1.815-2.865; P < 0.001). Conclusions: Serum iron levels affected the progression of chronic HBV infection. The prognosis of HBV- related HCC patients with serum iron levels <15.1 μmol/l together with higher AFP levels, worse BCLC stages, and larger tumor lesion were poor.
