Geriatric nutritional risk index as an easy-to-use assessment tool for nutritional status in hepatocellular carcinoma treated with atezolizumab plus bevacizumab

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.

Geriatric nutritional risk index and newly developed scoring system as prognosis prediction for unresectable hepatocellular carcinoma patients treated with lenvatinib

In the current era of immune therapy, lenvatinib (LEN) continues to be vital for treating unresectable hepatocellular carcinoma (uHCC) patients. This study investigates the importance of nutritional status in the prognosis of uHCC patients receiving LEN and evaluates a new prognostic scoring system that combines the geriatric nutritional risk index (GNRI) and systemic inflammatory response. From 2018 to 2022, 484 uHCC patients treated with LEN (384 males, median age 73). Prognostic value was compared between GNRI and C-reactive protein (CRP) scoring (GNRI-C score), GNRI, and neo-Glasgow prognostic score (neo-GPS). Evaluation was based on the Akaike information criterion (AIC) and concordance index(c-index). Median progression-free survival (mPFS) was 9.3/6.8/4.6 months for GNRI no-risk/low-risk/moderate-to-major risk (p < 0.01, AIC 4742.4/c-index 0.585). Median overall survival (mOS) was 27.8/15.2/9.5 months (p < 0.01, AIC 3433.34/c-index 0.639). For GNRI-C score, mPFS was 10.8/7.1/5.6/4.0 months (score 0/1/2/3) (p < 0.01, AIC 4732.82/c-index 0.6), while neo-GPS showed mPFS of 8.5/5.1/5.2 months (p < 0.01, AIC 4745.89/c-index 0.562). For mOS, GNRI-C score demonstrated 28.6/20.0/10.1/8.4 months (score 0/1/2/3) (p < 0.01, AIC 3420.27/c-index 0.652), while neo-GPS indicated 21.0/12.4/4.5 months (p < 0.01, AIC 3468.84/c-index 0.564). The newly devised GNRI-C score, incorporating nutritional and inflammatory markers, could offer improved prognostic predictions for uHCC patients treated with LEN.

Evaluation of Treatment Outcomes Using dNLR and GNRI in Combination Therapy With Atezolizumab and Bevacizumab for Hepatocellular Carcinoma

AIM

This study aims to investigate the clinical utility of the derived neutrophil-to-lymphocyte ratio (dNLR) and the Geriatric Nutritional Risk Index (GNRI) in predicting treatment outcomes for patients with unresectable hepatocellular carcinoma (HCC) undergoing combination therapy with atezolizumab and bevacizumab (Atez/Bev).

METHODS

A retrospective analysis was conducted on 310 patients. The dNLR, NLR, and GNRI were calculated, and their impact on progression-free survival (PFS) and overall survival (OS) was assessed. The formula for calculating dNLR is: (neutrophil count ÷ [white blood cell count-neutrophil count]), which means it does not require lymphocyte count. Furthermore, GNRI-dNLR and GNRI-NLR scores were defined, and their prognostic values were also analyzed.

RESULTS

The median PFS of this cohort was 7.2 months (95% CI: 5.9-8.5), and the median OS was 24.9 months (95% CI: 19.6-30.2). The dNLR, NLR, and GNRI were significant predictors of both PFS and OS. The dNLR showed a significant correlation with the NLR (Pearson correlation coefficient, p < 0.0001). Patients with high GNRI-dNLR scores demonstrated significantly worse PFS and OS compared to those with low scores (p = 0.001, p < 0.001, respectively). Compared to stratification by GNRI alone, the GNRI-dNLR or GNRI-NLR provided better stratification for both PFS and OS.

CONCLUSION

The dNLR could be a valuable substitute for NLR as a prognostic marker in patients with unresectable HCC undergoing Atez/Bev therapy. It offers a feasible alternative for databases lacking lymphocyte count information, ensuring comprehensive patient stratification and outcome prediction. The GNRI-NLR or GNRI-dNLR score provided better stratification compared to GNRI alone.

Grip strength complements performance status in assessing general condition in patients with unresectable hepatocellular carcinoma treated with atezolizumab and bevacizumab

AIM

An accurate assessment of the general condition of patients with hepatocellular carcinoma (HCC) is essential. We evaluated the impact of grip strength (GS) and Eastern Cooperative Oncology Group Performance Status (ECOG-PS) on the clinical outcomes of patients with unresectable HCC (u-HCC) treated with atezolizumab plus bevacizumab.

METHODS

This observational cohort study analyzed 89 patients with u-HCC treated with atezolizumab plus bevacizumab between October, 2020 and October, 2023. A Cox proportional hazards model and Kaplan-Meier curve were used to identify the prognostic factors associated with survival outcomes.

RESULTS

There were 33 patients who had low GS and 16 had an ECOG-PS ≥1. The frequency of patients with low GS increased as the ECOG-PS score increased. The overall survival of the normal GS group was significantly higher than that of the low GS group (p < 0.01). There was no significant difference in progression-free survival between the normal GS group and low-GS group (p = 0.28). Among the patients in the ECOG-PS 0 groups, the overall survival in the normal GS group was significantly higher than that in the low GS group (p < 0.01). A multivariate analysis revealed that modified albumin-bilirubin 2b (HR 2.24; 95% confidence interval [CI] 1.06-4.73), α-fetoprotein ≥100 ng/mL (HR 2.35; 95% CI 1.20-4.58), and low GS (HR 2.87; 95% CI 1.31-6.27) were independently associated with a poor overall survival.

CONCLUSIONS

The present study demonstrated that GS is a sensitive marker for detecting a subclinical decline in the general condition and is therefore a potential predictor of the outcome of u-HCC patients treated with atezolizumab plus bevacizumab.

CRAFITY score as a predictive marker for refractoriness to atezolizumab plus bevacizumab therapy in hepatocellular carcinoma: a multicenter retrospective study

BACKGROUND

Although atezolizumab plus bevacizumab (Atezo/Bev) therapy has been used as the preferred first-line treatment for advanced hepatocellular carcinoma (HCC), up to 26% of patients do not achieve disease control, suggesting alternative treatments might be more beneficial for such patients. We investigated key predictors for refractoriness to Atezo/Bev therapy, particularly in the first-line setting.

METHODS

We retrospectively analyzed 302 patients with HCC who received Atezo/Bev therapy between October 2020 and September 2022 across nine hospitals in Japan. Refractoriness was defined as best overall response (BOR) of progressive disease or stable disease and a progression-free survival (PFS) of < 180 days (RECIST v1.1). Clinical benefit was defined as BOR of partial/complete response or stable disease with PFS of ≥ 180 days. Baseline characteristics and potential predictors, identified through literature review, were compared between these groups. Stratifications of overall survival (OS), and PFS were also assessed.

RESULTS

Refractoriness was observed in 126 (41.7%) patients, while 154 (51.0%) achieved clinical benefit. Due to a significant association between the treatment line and refractory rate, the subsequent analysis focused on the first-line cohort (n = 214; 72 [33.6%] patients showed refractoriness). Among 13 potential predictors, the CRP and AFP in immunotherapy (CRAFITY) score had the best predictive performance, with refractory rates of 24.6%, 44.6%, and 57.9% in CRAFITY-0, 1, and 2 patients, respectively (p < 0.001). OS and PFS were also well-stratified by this scoring system.

CONCLUSIONS

Approximately one-third of patients were refractory to first-line Atezo/Bev therapy. The CRAFITY score demonstrated superior performance in predicting refractoriness.

Incorporating ALBI Grade with Geriatric Nutritional Risk Index Enhances Hepatocellular Carcinoma Risk Stratification

Introduction: Despite its prognostic impact, nutritional status has not yet been integrated into the assessment of hepatocellular carcinoma (HCC). This study investigated the association between geriatric nutritional risk index (GNRI) and overall survival (OS) in patients with HCC using a nationwide registry. Methods: Data from the Korea Central Cancer Registry between 2008 and 2019 were analyzed. We explored the integration of the GNRI with the albumin-bilirubin (ALBI) grade for prognostic stratification. Restricted cubic spline regression was used to assess the association between GNRI and survival, stratified by ALBI grade. Results: Among the 16,416 treatment-naïve HCC patients, the ALBI grades were distributed as follows: grade 1, 7,409; grade 2, 7,445; and grade 3, 1,562. Patients were categorized according to Barcelona Clinic Liver Cancer (BCLC) stages: 5,132 stage 0/A, 2,608 stage B, 5,289 stage C, and 968 stage D. The median OS for all patients was 3.1 years (95% CI: 3.0–3.2) and significantly differed with the inclusion of ALBI grade and GNRI (p < 0.001). The effect of combining ALBI grade and GNRI was further evaluated for each BCLC stage. This risk stratification showed a significant correlation with OS for each BCLC stage (all p < 0.001), except for stage D (p = 0.082). Multivariate analysis revealed that a combination of favorable ALBI grade and high GNRI score was independently associated with decreased mortality risk. Conclusion: The GNRI was significantly correlated with OS across ALBI grades and BCLC stages. Integrating the GNRI into the ALBI grade may enhance risk stratification for patients with HCC.

Dose-Reduction of Bevacizumab in Atezolizumab plus Bevacizumab Therapy Extends Treatment duration with Disease Control in Patients with Hepatocellular Carcinoma

INTRODUCTION

Atezolizumab (ATZ) and bevacizumab (BEV) combination therapy is widely used in patients with unresectable hepatocellular carcinoma (HCC). However, combination therapy is typically interrupted or discontinued owing to BEV-related adverse events. In this study, we examined the effects of BEV dose-reduction on the treatment of unresectable HCC using propensity score matching (PSM).

METHOD

Overall, 119 patients with HCC who were treated with ATZ + BEV between November 2020 and October 2022 were enrolled retrospectively at our institute. The therapeutic effects and safety of BEV dose-reduction and non-dose reduction after PSM were compared. Decision-tree analysis was used to investigate treatment duration in the patients.

RESULTS

Significant differences were not observed between the two groups after PSM. The objective response rate (ORR) and disease control rate (DCR) assessed by modified RECIST did not differ significantly between the two groups (BEV non-dose-reduction/dose-reduction: ORR; 46/34%, DCR; 80/91%). Progression-free survival (PFS) and overall survival (OS) also did not differ significantly between the two groups (BEV non-dose-reduction/dose-reduction: PFS; 5.6/8.6 months, OS; 18.6/15.5 months). The median duration of treatment in the BEV dose-reduction group was significantly longer than that in the non-dose-reduction group (BEV non-dose-reduction/dose-reduction: 4.8/9.1 months, p = 0.038). Decision-tree analysis revealed that dose-reduction of BEV was the first distinguish factor for the extension of treatment duration with ATZ + BEV.

CONCLUSION

BEV dose-reduction can be effectively used in maintaining the treatment duration of ATZ + BEV while maintaining therapeutic effects and safety in real-world clinical practice.

The Negative Impact of Sarcopenia on Hepatocellular Carcinoma Treatment Outcomes

INTRODUCTION

Hepatocellular carcinoma (HCC) represents a major global health concern, characterized by evolving etiological patterns and a range of treatment options. Among various prognostic factors, sarcopenia, characterized by loss of skeletal muscle mass, strength, and function, has emerged as a pivotal contributor to HCC outcomes. Focusing on liver transplantation, surgical resection, locoregional treatments, and systemic therapies, this review aims to analyze the impact of sarcopenia on HCC treatment outcomes, shedding light on an underexplored subject in the pursuit of more personalized management.

METHODS

A comprehensive literature review was conducted by searching peer-reviewed articles on sarcopenia and treatment outcomes in patients with HCC from inception up to October 2023.

RESULTS

Sarcopenia was found to be prevalent among HCC patients, exhibiting different occurrence, possibly attributable to diverse diagnostic criteria. Notably, despite variations in studies utilizing skeletal muscle indices, sarcopenia independently correlated with lower overall survival (OS), recurrence-free survival (RFS), and progression-free survival (PFS) across surgical (both transplantation and resection), locoregional, and systemic therapies, including tyrosine-kinase inhibitors (TKIs) and immune-checkpoint inhibitors (ICIs). Moreover, a link between sarcopenia and increased rate and severity of adverse events, particularly in surgery and TKIs recipients, and larger tumor size at diagnosis was observed. While baseline sarcopenia negatively influenced treatment outcomes, alterations in muscle mass post-treatment emerged as primary determinants of reduced OS.

CONCLUSIONS

Sarcopenia, either present before or after HCC treatment, negatively correlates with response to it, across all etiologies and therapeutic strategies. Although only a few studies have evaluated the impact of supervised physical activity training on muscle mass and OS after HCC treatment, it is crucial to evaluate the presence of sarcopenia before treatment initiation, to better stratify patients' prognosis, thus performing a more tailored approach, and identify therapies able to restore muscle mass in HCC patients. Conversely, the impact of sarcopenia on HCC recurrence and extrahepatic spread remains inadequately explored.

Clinical usefulness of newly developed prognostic predictive score for atezolizumab plus bevacizumab for hepatocellular carcinoma

AIMS

The aim of the present study was to elucidate detailed parameters for prediction of prognosis for patients with unresectable hepatocellular carcinoma (uHCC) receiving atezolizumab plus bevacizumab (Atez/Bev) treatment.

METHODS

A total of 719 patients (males 577, median age 74 years) treated with Atez/Bev between September 2020 and January 2023 were enrolled. Factors related to overall survival (OS) were extracted and a prognostic scoring system based on hazard ratio (HR) was created. OS and progression-free survival (PFS) were retrospectively examined, and the prognostic ability of the newly developed system was compared to CRAFITY score using concordance index (c-index) and Akaike information criterion (AIC) results.

RESULTS

Cox-hazards multivariate analysis showed BCLC classification C/D (HR 1.4; 1 point), AFP ≥100 ng/mL (HR 1.4; 1 point), mALBI 2a (HR 1.7; 1 point), mALBI 2b/3 (HR 2.8; 2 points), and DCP ≥100 mAU/mL (HR 1.6; 1 point) as significant factors. The assigned points were added and used to develop the IMmunotherapy with AFP, BCLC staging, mALBI, and DCP evaluation (IMABALI-De) scoring system. For IMABALI-De scores of 0, 1, 2, 3, 4, and 5, OS was not applicable (NA), NA, 26.11, 18.79, 14.07, and 8.32 months, respectively (p < .001; AIC 2788.67, c-index 0.699), while for CRAFITY scores of 0, 1, and 2, OS was 26.11, 20.29, and 11.32 months, respectively (p < .001; AIC 2864.54, c-index 0.606). PFS periods for those IMABALI-De scores were 21.75, 12.89, 9.18, 8.0, 5.0, and 3.75 months, respectively (p < .001; AIC 5203.32, c-index 0.623) and for the CRAFITY scores were 10.32, 7.68, and 3.57 months, respectively (p < .001; AIC 5246.61, c-index 0.574). As compared with CRAFITY score, IMABALI-De score had better AIC and c-index results for both OS and PFS.

CONCLUSION

The present results indicated that the proposed IMABALI-De score may be favorable for predicting prognosis of uHCC patients receiving Atez/Bev therapy.

Lower Geriatric Nutritional Risk Index and Prognostic Nutritional Index Predict Postoperative Prognosis in Patients with Hepatocellular Carcinoma

Increasing evidence suggests that nutritional indices, including the geriatric nutritional risk index (GNRI) and prognostic nutritional index (PNI), are predictors of poor prognosis in patients with hepatocellular carcinoma (HCC). Hence, this study aimed to explore the value of the GNRI and PNI in evaluating postoperative prognosis in patients with HCC, particularly regarding its recurrence patterns. We performed a retrospective analysis of 203 patients with HCC who underwent initial hepatic resection. Patients were divided into two groups according to the GNRI (cutoff: 98) and PNI (cutoff: 45). The GNRI and PNI were significantly associated with body composition (body mass index and skeletal muscle mass index), hepatic function (Child-Pugh Score), tumor factors (tumor size and microvascular invasion), and perioperative factors (blood loss and postoperative hospitalization). Patients with a low PNI or low GNRI had significantly worse overall survival (OS) and recurrence-free survival. Patients with early recurrence had lower PNI and GNRI scores than those without early recurrence. Patients with extrahepatic recurrence had lower PNI and GNRI scores than those without extrahepatic recurrence. The PNI and GNRI might be useful in predicting the prognosis and recurrence patterns of patients with HCC after hepatic resection.

Predictors of Survival in Patients With Hepatocellular Cancer Receiving Atezolizumab and Bevacizumab

OBJECTIVES

In randomized clinical trials in patients with hepatocellular cancer (HCC), combination therapy with atezolizumab and bevacizumab (Atezo-Bev) prolonged survival, and these treatments have become the standard first-line therapy for advanced HCC. However, clinical trials may not reflect real-life clinical practice due to treatment selection criteria. Thus, our aim was to understand predictors of HCC outcomes with these treatments in a real-world, multicenter setting.

METHODS

A retrospective review of all patients 18 years of age or older treated for advanced primary liver cancer between February 2020 and August 2022 was conducted to assess the relationship between overall survival and clinical and biochemical variables before or during treatment. Univariate and multivariate Cox regression survival analyses were performed to identify predictors of survival following treatment.

RESULTS

One hundred and eleven eligible patients with unresectable HCC received Atezo-Bev over a consecutive 30-month period. Cox regression identified several significant ( P <0.05) predictors of survival, including pretreatment albumin (hazard ratios [HR]: 0.2; CI: 0.1-0.4), total bilirubin (HR: 1.3; CI: 1.2-1.5), and international normalized ratio (HR: 5.6; CI: 2.5-12.5). In multivariate analyses, these were significantly associated as predictors of mortality, and patients with pretreatment albumin <3.5 mg/dL had significantly lower survival than those ≥3.5 (153 vs. 522 d, P <0.0001).

CONCLUSIONS

Pretreatment hypoalbuminemia, high bilirubin, and biochemical tests indicative of hepatic or renal dysfunction can independently predict short-term mortality in advanced HCC patients receiving Atezo-Bev.

A Low Geriatric Nutritional Risk Index Is Associated with Low Muscle Volume and a Poor Prognosis among Cirrhotic Patients

Background and Objectives: The geriatric nutritional risk index (GNRI) is an easily calculable index that can be determined using three common clinical variables. The GNRI is suggested to be related to sarcopenia in cirrhotic patients. However, the relationship between the GNRI and the prognosis in patients with liver cirrhosis (LC) has not been reported. The aim of the present research is to study the association of the GNRI with the nutritional status, hepatic function reserve, and prognosis in patients with liver cirrhosis (LC). Materials and Methods: A total of 370 cirrhotic patients whose nutritional statuses were evaluated using anthropometric measurements and bioimpedance analysis were studied. The associations between the GNRI and nutritional status and the GNRI and hepatic function reserve were analyzed. We also investigated the GNRI and prognosis of patients with LC. Results: The median age of the enrolled patients was 66 years old, and 266 (71.9%) patients had viral hepatitis-related LC. The GNRI was shown to decrease with the progression of chronic liver disease, represented by an increased FIB-4 index and severe Child-Pugh and mALBI grades. In addition, a low GNRI (<92) was associated with severe cirrhosis-related metabolic disorders, including a low branched-chain amino acid-to-tyrosine ratio (BTR) and a low zinc value. The GNRI was positively correlated with two nutrition-related anthropometric variables (% arm circumference and % arm muscle circumference), and a low GNRI was related to a low skeletal muscle mass index (SMI) (<7.0 kg/m2 for men or <5.7 kg/m2 for women), as determined by using bioimpedance analysis. In addition, patients with a low GNRI (<92) had a poorer prognosis than those with a high GNRI (≥92) (log-rank test: p = 0.0161, and generalized Wilcoxon test, p = 0.01261). Conclusions: Our results suggest that a low GNRI is related to severe chronic liver disease, low muscle volume, and a poor prognosis of patients with cirrhosis.

Low geriatric nutritional risk index as a poor prognostic biomarker for immune checkpoint inhibitor treatment in solid cancer

Objective

In this investigation, we focused on the geriatric nutritional risk index (GNRI), a comprehensive metric that takes into account the patient's ideal weight, actual weight, and serum albumin levels to measure malnutrition. Our primary objective was to examine the predictive value of GNRI-defined malnutrition in determining the response to immunotherapy among cancer patients.

Methods

Relevant articles for this study were systematically searched in PubMed, the Cochrane Library, EMBASE, and Google Scholar up to July 2023. Our analysis evaluated overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR) as clinical outcomes.

Results

This analysis comprised a total of eleven articles encompassing 1,417 patients. The pooled results revealed that cancer patients with low GNRI levels exhibited shorter OS (HR: 2.64, 95% CI: 2.08-3.36, p < 0.001) and PFS (HR: 1.87, 95% CI: 1.46-2.41, p < 0.001), and lower ORR (OR: 0.46, 95% CI: 0.33-0.65, p < 0.001) and DCR (OR: 0.42, 95% CI: 0.29-0.61, p < 0.001). Sensitivity analyses confirmed that the above results were stable. Egger's and Begg's tests revealed that there was no publication bias in the above results.

Conclusion

Our results imply that the GNRI is a useful predictor of immunotherapy response in cancer patients.
