Neutrophil-to-lymphocyte ratio is associated with survival in patients with unresectable hepatocellular carcinoma treated with lenvatinib

Dynamics of the neutrophil‑to‑lymphocyte ratio during lenvatinib treatment for unresectable hepatocellular carcinoma

Lenvatinib is an approved therapy for advanced hepatocellular carcinoma (HCC). Recently, immune checkpoint inhibitors have been approved as frontline chemotherapies for HCC, and the tumor immune microenvironment (TIME) has been demonstrated to significantly affect HCC treatment. The neutrophil-to-lymphocyte ratio (NLR) is associated with the TIME, and the dynamics of the NLR are associated with prognosis or treatment efficacy in various cancer types. The present study investigated the dynamics of the TIME using the NLR in 101 patients with HCC treated with lenvatinib. Immunostaining for CD8+ tumor-infiltrating lymphocytes (TILs) was also performed in 9 patients who underwent liver tumor biopsy prior to subsequent chemotherapy for progression or discontinuation due to adverse events on lenvatinib treatment. The NLR values measured at the start of treatment (SOT), after 1 month of treatment and after 3 months of treatment were 2.78±2.20, 2.61±1.86 and 2.66±2.36, respectively (P=0.733). Among the patients with no reduction in the initial dose, there was no significant difference between the NLR after 1 month (2.34±0.25) and that at the SOT (2.86±2.33) (P=0.613). In patients who achieved a complete or partial response, the NLR at the time of the best tumor response was 1.65±0.56, which was significantly lower than that at the SOT (2.05±0.78) (P=0.023). In patients who did not respond to lenvatinib, the NLR at the time of disease progression was 3.68±3.19, which was significantly higher than that at the SOT (2.78±1.79) (P=0.043). Overall, 5 out of the 6 patients who did not respond to lenvatinib had low CD8+ TIL counts at disease progression. Although the present study included a limited number of patients, the NLR was associated with the therapeutic effects of lenvatinib. These findings suggest the potential of lenvatinib as an immunomodulator.

Pretreatment Neutrophil-to-Lymphocyte Ratio as Prognostic Biomarkers in Patients with Unresectable Hepatocellular Carcinoma Treated with Hepatic Arterial Infusion Chemotherapy Combined with Lenvatinib and Camrelizumab

Purpose

This study aimed to assess the prognostic significance of the neutrophil-lymphocyte ratio (NLR) in patients with unresectable hepatocellular carcinoma (u-HCC) treated with hepatic artery infusion chemotherapy (HAIC) combined with lenvatinib and camrelizumab.

Patients and Methods

We conducted a retrospective cohort study involving patients diagnosed with u-HCC who underwent HAIC combined with lenvatinib and camrelizumab. Patients were stratified into two cohorts using the median NLR as the cutoff point. We then assessed treatment response, overall survival (OS), progression-free survival (PFS), and adverse events in these patient groups.

Results

Between October 2020 and April 2022, a total of 88 patients were enrolled in the study. The overall cohort exhibited a median PFS of 7.9 months, while the median OS was not reached, and a median NLR of 3.46. Notably, the group with NLR<3.46 demonstrated significantly superior OS (not reached vs 9.6 months, p = 0.017) and PFS (18.3 vs 5.3 months, p = 0.0015) compared to the NLR≥3.46 group. Furthermore, multivariate analysis revealed that an alpha-fetoprotein (AFP) ≥ 400 ng/mL [hazard ratio (HR), 2.133; 95% confidence interval (CI), 1.102-4.126; p = 0.024], Barcelona Clinical Hepatocellular Carcinoma (BCLC) stage C (HR, 2.319; 95% CI, 1.128-4.764; p = 0.022), and NLR ≥3.46 (HR, 2.35; 95% CI, 1.239-4.494; p = 0.009) were identified as independent risk factors for OS. Additionally, multivariate analysis demonstrated that AFP ≥ 400 ng/mL, BCLC stage C, and NLR ≥ 3.46 were independent negative factors of PFS.

Conclusion

NLR can be associated with outcomes in patients with u-HCC treated with HAIC combined with lenvatinib and camrelizumab.

Population Pharmacokinetics and Exposure-Response Analysis of Tremelimumab 300 mg Single Dose Combined with Durvalumab 1500 mg Q4W (STRIDE) in Patients with Unresectable Hepatocellular Carcinoma

A novel single-dose regimen of 300 mg tremelimumab in combination with durvalumab (STRIDE) has demonstrated a favorable benefit-risk profile in the phase 1/2 Study 22 trial (in patients with unresectable hepatocellular carcinoma, uHCC) and in the phase 3 HIMALAYA study. The current analysis evaluated the population pharmacokinetics (PopPK) of tremelimumab and durvalumab, and the exposure-response (ER) relationship for efficacy and safety of STRIDE in patients with uHCC. Previous PopPK models for tremelimumab and durvalumab were updated using data from previous studies in various cancers combined with data from Study 22 and HIMALAYA. Typical population mean parameters and associated inter- and intra-individual variability were assessed, as was the influence of covariates. Individual exposure metrics were derived from the individual empirical Bayes estimates as drivers for ER analysis related to efficacy and safety from HIMALAYA. The observed pharmacokinetics of tremelimumab in uHCC were well described by a 2-compartment model with both linear and time-dependent clearance. All identified covariates changed tremelimumab PK parameters by <25%, and thus had minimal clinical relevance; similar results were obtained from durvalumab PopPK analysis. None of tremelimumab or durvalumab exposure metrics were significantly associated with overall survival (OS), progression-free survival (PFS), or adverse events. Baseline aspartate aminotransferase and neutrophil-to-lymphocyte ratio (NLR) were associated with OS (P < .001) by the Cox proportional hazards model. No covariate was identified as a significant factor for PFS. No dose adjustment for tremelimumab or durvalumab is needed based on PopPK covariate analyses or ER analyses. Our findings support the novel STRIDE dosing regimen in patients with uHCC.

The rapidly evolving landscape of HCC: Selecting the optimal systemic therapy

Over the past years, there has been a remarkable advance in the systemic treatment options for advanced HCC. The overall survival has gradually increased over time, with larger benefits for patients with sensitive tumors and preserved liver function, the latter being an essential condition for the delivery of sequential lines of treatment and optimization of clinical outcomes. With the approval of new first-line agents and the introduction of immune checkpoint inhibitor-based therapies, the treatment landscape of advanced HCC is becoming wider than ever. Atezolizumab plus bevacizumab and, more recently, durvalumab plus tremelimumab have entered the clinical practice and are the current standard of care for treatment-naïve patients, surpassing sorafenib and lenvatinib monopoly. As no head-to-head comparisons are available among all the first-line treatment options, the recommendation for the most appropriate choice and sequence is patient-driven and integrates efficacy data with clinical comorbidities, background liver disease, and the safety profile of available drugs. In addition, predictive biomarkers for successful patients' stratification are yet to be available and constitute the focus of ongoing research. The treatment algorithm is likely to become even more complex since systemic therapeutic approaches are now being translated into earlier stages of the disease, with an impact on the evolution of the sequential treatment of patients with HCC.

Potential Predictive Biomarkers of Systemic Drug Therapy for Hepatocellular Carcinoma: Anticipated Usefulness in Clinical Practice

In the systemic drug treatment of hepatocellular carcinoma, only the tyrosine kinase inhibitor (TKI) sorafenib was available for a period. This was followed by the development of regorafenib as a second-line treatment after sorafenib, and then lenvatinib, a new TKI, proved non-inferiority to sorafenib and became available as a first-line treatment. Subsequently, cabozantinib, another TKI, was introduced as a second-line treatment, along with ramucirumab, the only drug proven to be predictive of therapeutic efficacy when AFP levels are >400 ng/mL. It is an anti-VEGF receptor antibody. More recently, immune checkpoint inhibitors have become the mainstay of systemic therapy and can now be used as a first-line standard treatment for HCC. However, the objective response rate for these drugs is currently only 30% to 40%, and there is a high incidence of side effects. Additionally, there are no practical biomarkers to predict their therapeutic effects. Therefore, this review provides an overview of extensive research conducted on potential HCC biomarkers from blood, tissue, or imaging information that can be used in practice to predict the therapeutic efficacy of systemic therapy before its initiation.

Pretreatment lymphocyte-to-monocyte ratio as a prognostic factor and influence on dose-effect in fractionated stereotactic radiotherapy for oligometastatic brain metastases in non-small cell lung cancer patients

Background

Studies on the prognostic factors for patients with brain oligo-metastasis treated with fractionated stereotactic radiotherapy (FSRT) usually focus on the size of metastatic tumor and radiation dose. Some inflammatory indicators have predictive value in non-small cell lung cancer (NSCLC) with brain metastasis receiving stereotactic radiotherapy. However, the prognostic value of inflammatory indicators in NSCLC patients with brain oligo-metastasis treated with FSRT, and their effect on radiotherapy dose is unknown.

Methods

A total of 95 advanced NSCLC patients with brain oligo-metastasis who had undergone FSRT treatment at Ningbo Medical Center Lihuili Hospital between January 2015 and April 2022 were enrolled into the study. Neutrophil to lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), tumor diameter and biologically effective dose (BED10) were analyzed using Chi-square test. Univariate and multivariate Cox regressions were used to identify predictors of survival.

Results

Tumor diameter (< 2 cm), BED10 (≥ 48Gy) and LMR (≥ 4) were found to be independently associated with good intracranial local control survival (i-LCS) through multivariate analysis. The median i-LCS was longer in patients with 2 independent risk factors (tumor diameter ≥ 2 and LMR < 4) administered with BED10 > 53.6Gy compared with patients administered with BED10 ≤ 53.6Gy (20.7 months vs 12.0 months, P = 0.042). LMR ≥ 4 (P = 0.019) and positivity for driver gene mutations (P = 0.011) were independently associated with better overall survival (OS).

Conclusions

LMR is an independent prognostic factor of i-LCS and OS in NSCLC patients with brain oligo-metastasis treated with FSRT. Patients with tumor diameter ≥ 2 and LMR < 4 should be treated with BED10 greater than 53.6Gy.

Combination of alpha-fetoprotein and neutrophil-to-lymphocyte ratio to predict treatment response and survival outcomes of patients with unresectable hepatocellular carcinoma treated with immune checkpoint inhibitors

BACKGROUND

Immune-checkpoint inhibitors (ICIs) have revolutionized the treatment of hepatocellular carcinoma (HCC). However, long-term survival outcomes and treatment response of HCC patients undergoing immunotherapy is unpredictable. The study aimed to evaluate the role of alpha-fetoprotein (AFP) combined with neutrophil-to-lymphocyte ratio (NLR) to predict the prognosis and treatment response of HCC patients receiving ICIs.

METHODS

Patients with unresectable HCC who received ICI treatment were included. The HCC immunotherapy score was developed from a retrospective cohort at the Eastern Hepatobiliary Surgery Hospital to form the training cohort. The clinical variables independently associated with overall survival (OS) were identified using univariate and multivariate Cox regression analysis. Based on multivariate analysis of OS, a predictive score based on AFP and NLR was constructed, and patients were stratified into three risk groups according to this score. The clinical utility of this score to predict progression-free survival (PFS) and differentiate objective response rate (ORR) and disease control rate (DCR) was also performed. This score was validated in an independent external validation cohort at the First Affiliated Hospital of Wenzhou Medical University.

RESULTS

Baseline AFP ≤ 400 ng/ml (hazard ratio [HR] 0.48; 95% CI, 0.24-0.97; P = 0.039) and NLR ≤ 2.77 (HR 0.11; 95% CI, 0.03-0.37; P<0.001) were found to be independent risk factors of OS. The two labolatory values were used to develop the score to predict survival outcomes and treatment response in HCC patients receiving immunotherapy, which assigned 1 point for AFP > 400 ng/ml and 3 points for NLR > 2.77. Patients with 0 point were classified as the low-risk group. Patients with 1-3 points were categorized as the intermediate-risk group. Patients with 4 points were classified as the high-risk group. In the training cohort, the median OS of the low-risk group was not reached. The median OS of the intermediate-risk group and high-risk group were 29.0 (95% CI 20.8-37.3) months and 16.0 (95% CI 10.8-21.2) months, respectively (P < 0.001). The median PFS of the low-risk group was not reached. The median PFS of the intermediate-risk group and high-risk group were 14.6 (95% CI 11.3-17.8) months and 7.6 (95% CI 3.6-11.7) months, respectively (P < 0.001). The ORR and DCR were highest in the low-risk group, followed by the intermediate-risk group and the high-risk group (P < 0.001, P = 0.007, respectively). This score also had good predictive power using the validation cohort.

CONCLUSION

The HCC immunotherapy score based on AFP and NLR can predict survival outcomes and treatment response in patients receiving ICI treatments, suggesting that this score could serve as a useful tool for identification of HCC patients likely to benefit from immunotherapy.

Platelet-to-lymphocyte ratio a potential prognosticator in acute myocardial infarction: A prospective longitudinal study

BACKGROUND

The ratio of platelets to lymphocytes (PLR) can serve as a potential biomarker for predicting the prognosis of individuals with acute myocardial infarction (AMI).

AIM

The purpose of the research was to evaluate the in-hospital outcomes of AMI patients and the predictive significance of PLR on major adverse cardiac events (MACE).

METHODS

A total of 799 AMI patients who had successful primary PCI within 12 h of the onset of chest pain were separated into low PLR (n = 511) and high PLR (n = 288) groups using a PLR cutoff value of 178. At admission, total white blood cell, neutrophil, lymphocyte, and platelet counts were assessed.

RESULTS

In patients with a high PLR group with PLR > 178, the incidence of MACE: heart rupture, acute heart failure, total adverse events, and mortality due to all events was considerably greater. In an analysis of the receiver operating characteristic curve, a high PLR > 178 accurately predicted adverse outcomes (73% specificity and 65% sensitivity). Age, hypertension, and PLR were found as independent predictors of adverse outcomes by multiple logistic regression.

CONCLUSIONS

AMI patients with high PLR had poor hospital outcomes. These findings recommend PLR as an independent risk factor for hospital-acquired complications, suggesting that inflammation and prothrombotic state may contribute to the poor prognosis of high PLR patients.

Blood biomarkers predict outcomes in patients with hepatocellular carcinoma treated with immune checkpoint Inhibitors: A pooled analysis of 44 retrospective sudies

OBJECTIVE

We conducted the first meta-analysis to identify the predictive significance of baseline blood biomarkers (such as neutrophil to lymphocyte ratio (NLR), early alpha-fetoprotein (AFP) response, albumin-bilirubin (ALBI), AFP, platelet to lymphocyte ratio (PLR), C-reactive protein (CRP), protein induced by vitamin K absence II (PIVKA-II), and lymphocyte to monocyte ratio (LMR)) in hepatocellular carcinoma (HCC) patients treated with immune checkpoint inhibitors (ICIs).

METHODS

Eligible articles were retrieved using PubMed, the Cochrane Library, EMBASE, and Google Scholar by November 24, 2022. Clinical outcomes were overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and hyperprogressive disease (HPD).

RESULTS

A total of 44 articles with 5322 patients were included in this meta-analysis. The pooled results demonstrated that patients with high NLR levels had significantly poorer OS (HR: 1.951, P < 0.001) and PFS (HR: 1.632, P < 0.001), lower ORR (OR: 0.484, P < 0.001) and DCR (OR: 0.494, P = 0.027), and higher HPD (OR: 8.190, P < 0.001). The patients with high AFP levels had shorter OS (HR: 1.689, P < 0.001) and PFS (HR: 1.380, P < 0.001), and lower DCR (OR: 0.440, P < 0.001) than those with low AFP levels, however, there was no difference in ORR (OR: 0.963, P = 0.933). We also found that early AFP response was correlated with better OS (HR: 0.422, P < 0.001) and PFS (HR: 0.385, P < 0.001), higher ORR (OR: 7.297, P < 0.001) and DCR (OR: 13.360, P < 0.001) compared to non-responders. Besides, a high ALBI grade was significantly related to shorter OS (HR: 2.440, P = 0.009) and PFS (HR: 1.373, P = 0.022), lower ORR (OR: 0.618, P = 0.032) and DCR (OR: 0.672, P = 0.049) than those with an ALBI grade 1.

CONCLUSION

The NLR, early AFP response, and ALBI were useful predictors of outcomes in HCC patients treated with ICIs.

Effectiveness and safety of lenvatinib plus anti-programmed death-1 antibodies in patients with hepatocellular carcinoma: A real-world cohort study

OBJECTIVE

Lenvatinib plus anti-programmed death-1 (anti-PD-1) antibody combinations have shown potent anti-tumor effect in phase I/II trials in advanced or unresectable hepatocellular carcinoma (HCC), but real-world data are limited.

METHODS

To investigate the effectiveness and safety of lenvatinib plus anti-PD-1 antibodies in a real-world cohort, we retrospectively evaluated 210 patients with unresectable or advanced HCC treated with these regimens between October 2018 and February 2022.

RESULTS

The objective response rate and disease control rate per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 were 28.1% and 75.2%. Median overall survival (OS) and progression-free survival (PFS) in the overall cohort were 17.2 and 8.4 months, respectively. Median OS and PFS of patients receiving first-line treatment reached 18.9 and 9.6 months. Median OS was significantly longer in patients with Child-Pugh class A versus B (18.8 vs. 5.9 months, respectively), as was median PFS (9.1 vs. 4.4 months). Patients with albumin-bilirubin (ALBI) grade 1 versus grade 2/3 also had significantly greater median OS (23.5 vs. 13.4 months). Treatment-related adverse events (AEs) occurred in 79.5% of patients. Patients with ALBI grade 2/3 had a higher rate of grade 3/4 AEs than patients with ALBI grade 1 (57.5% vs. 38.5%).

CONCLUSION

Lenvatinib combined with anti-PD-1 antibody therapy was effective in patients with sufficient liver function reserve. Further study is needed to improve therapeutic efficacy and AE management in patients with Child-Pugh class B or ALBI grade 2/3.

The neutrophil-to-lymphocyte ratio at the start of the second course during atezolizumab plus bevacizumab therapy predicts therapeutic efficacy in patients with advanced hepatocellular carcinoma: A multicenter analysis

AIM

Atezolizumab plus bevacizumab (Atez/Bev) therapy is expected to have good therapeutic efficacy for patients with advanced hepatocellular carcinoma (HCC). However, the clinical indicators that predict therapeutic efficacy have not been established. We retrospectively investigated whether the neutrophil-to-lymphocyte ratio (NLR) during Atez/Bev therapy could predict therapeutic efficacy.

METHOD

In total, 110 patients with HCC were enrolled; they were treated with Atez/Bev therapy and evaluated for their initial response by dynamic CT or MRI at least once between October 2020 and July 2022.

RESULTS

Of the 110 patients with HCC at the initial evaluation, two (2%) showed a complete response (CR), 22 (20%) partial response (PR), 62 (56%) stable disease (SD), and 24 (21%) progressive disease (PD). The NLR at the start of the second course (NLR-2c) increased from CR + PR to SD to PD. There was no significant association between the baseline NLR and the initial therapeutic response. Patients with CR + PR had lower NLR-2c values than those with SD + PD (p < 0.001) and the optimal cut-off value of NLR-2c was 1.97. Patients with NLR-2c <1.97 had better overall survival and progression-free survival (PFS) than those with NLR-2c ≥1.97 (p = 0.005 for overall survival; p < 0.001 for PFS). A multivariate analysis showed that female sex, higher PIVKA-II levels at baseline, and higher values of NLR-2c were significantly associated with poorer PFS.

CONCLUSIONS

The NLR-2c value predicts the initial therapeutic response and prognosis of patients with HCC treated with Atez/Bev therapy.

Machine Learning to Predict the Response to Lenvatinib Combined with Transarterial Chemoembolization for Unresectable Hepatocellular Carcinoma

BACKGROUND

Lenvatinib and transarterial chemoembolization (TACE) are first-line treatments for unresectable hepatocellular carcinoma (HCC), but the objective response rate (ORR) is not satisfactory. We aimed to predict the response to lenvatinib combined with TACE before treatment for unresectable HCC using machine learning (ML) algorithms based on clinical data.

METHODS

Patients with unresectable HCC receiving the combination therapy of lenvatinib combined with TACE from two medical centers were retrospectively collected from January 2020 to December 2021. The response to the combination therapy was evaluated over the following 4-12 weeks. Five types of ML algorithms were applied to develop the predictive models, including classification and regression tree (CART), adaptive boosting (AdaBoost), extreme gradient boosting (XGBoost), random forest (RF), and support vector machine (SVM). The performance of the models was assessed by the receiver operating characteristic (ROC) curve and area under the receiver operating characteristic curve (AUC). The Shapley Additive exPlanation (SHAP) method was applied to explain the model.

RESULTS

A total of 125 unresectable HCC patients were included in the analysis after the inclusion and exclusion criteria, among which 42 (33.6%) patients showed progression disease (PD), 49 (39.2%) showed stable disease (SD), and 34 (27.2%) achieved partial response (PR). The nonresponse group (PD + SD) included 91 patients, while the response group (PR) included 34 patients. The top 40 most important features from all 64 clinical features were selected using the recursive feature elimination (RFE) algorithm to develop the predictive models. The predictive power was satisfactory, with AUCs of 0.74 to 0.91. The SVM model and RF model showed the highest accuracy (86.5%), and the RF model showed the largest AUC (0.91, 95% confidence interval (CI): 0.61-0.95). The SHAP summary plot and decision plot illustrated the impact of the top 40 features on the efficacy of the combination therapy, and the SHAP force plot successfully predicted the efficacy at the individualized level.

CONCLUSIONS

A new predictive model based on clinical data was developed using ML algorithms, which showed favorable performance in predicting the response to lenvatinib combined with TACE for unresectable HCC. Combining ML with SHAP could provide an explicit explanation of the efficacy prediction.

Therapeutic effect of postoperative adjuvant transcatheter arterial chemoembolization based on the neutrophil-to-lymphocyte ratio

Aim

To evaluate the feasibility of the preoperative neutrophil-to-lymphocyte ratio (NLR) as an index to guide postoperative adjuvant transcatheter arterial chemoembolization (PA-TACE) in patients with liver cancer.

Methods

We recruited a total of 166 patients with liver cancer who underwent surgery alone or surgery plus PA-TACE between January 2013 and June 2017 and compared the 1, 2, and 3-year recurrence-free survival (RFS) and overall survival (OS) between patients with high and low NLRs, surgery and surgery plus PA-TACE groups, and relevant subgroups using the Kaplan-Meier method. We also evaluated the independent factors affecting the prognosis of liver cancer after surgery using a Cox risk ratio model and correlation between NLR levels and high-risk recurrence factors of liver cancer with logistic regression analysis.

Results

The 1, 2, and 3-year RFS rates were all significantly higher in the low-NLR group compared to the high-NLR group (P < 0.05). However, the 1, 2, and 3-year OS rates were similar in the low- and high-NLR groups (P > 0.05). After propensity score matching, the 1, 2, and 3-year RFS and OS rates were significantly better in patients treated with surgery plus PA-TACE compared with surgery alone (P < 0.05). The 1, 2, and 3-year RFS and OS rates were also significantly better in the surgery plus PA-TACE subgroup compared with the surgery-alone subgroup in the high-NLR group (P < 0.05), but there was no significant difference in RFS or OS between the surgery plus PA-TACE and surgery-alone subgroups at 1, 2, and 3 years in the low-NLR group (P > 0.05). Multivariate analysis in the high-NLR group showed that a poorly differentiated or undifferentiated tumor was an independent risk factor for postoperative RFS. Multiple tumors were an independent risk factor for postoperative OS (P < 0.05), while PA-TACE was an independent protective factor for postoperative RFS and OS (P < 0.05). In the low-NLR group, AFP > 400 µg/L was an independent risk factor for postoperative OS (P < 0.05). Multivariate logistic regression indicated that patients with a maximum tumor diameter of >5 cm were at increased risk of having high NLR levels compared to patients with a maximum tumor diameter of <5 cm (P < 0.05).

Conclusion

PA-TACE can improve the prognosis of patients with a high preoperative NLR (≥2.5), but has no obvious benefit in patients with low preoperative NLR (<2.5). This may provide a reference for clinical selection of PA-TACE.

Usefulness of neutrophil-to-lymphocyte ratio in predicting progression and survival outcomes after atezolizumab-bevacizumab treatment for hepatocellular carcinoma

AIM

We investigated pretreatment neutrophil-to-lymphocyte ratio (NLR) for predicting survival outcomes of atezolizumab plus bevacizumab therapy for hepatocellular carcinoma (HCC) and determined the predictive ability of combined liver reserve-NLR.

METHODS

This retrospective, multicenter study enrolled 242 patients receiving atezolizumab plus bevacizumab for unresectable HCC. Pretreatment NLR <2.56 was designated as the "low group" and NLR ≥2.56 as the "high group" (120 and 122 patients, respectively). Propensity score-matched analysis was undertaken between the low and high groups.

RESULTS

In this cohort, the objective response and disease control rates were 20% and 72.5%, respectively, in the low group and 19.6% and 72.9%, respectively, in the high group. After matching, median progression-free survival (PFS) time was 283 and 167 days in the low and high groups, respectively (p = 0.022). Neutrophil-to-lymphocyte ratio ≥2.56 (hazard ratio [HR], 1.54; 95% confidence interval [CI], 1.05-2.28; p = 0.028), modified albumin-bilirubin index (mALBI) grade 2b or 3 (HR 1.55; 95% CI, 1.05-2.29; p = 0.025), and protein induced by vitamin K absence or antagonist-II ≥ 400 (HR 2.03; 95% CI, 1.36-3.02; p = 0.001) were significantly associated with PFS in univariate analysis using the Cox proportional hazards model. In cases involving mALBI grade 1 or 2a (n = 131), the median PFS time was not reached in the low group, whereas it was 210 days in the high group (p = 0.037).

CONCLUSIONS

Pretreatment NLR is a simple tool for routine measurement in clinical practice. It can predict PFS in patients with unresectable HCC treated with atezolizumab plus bevacizumab, especially mALBI grade 1 or 2a.

Neutrophil-to-Lymphocyte Ratio and Early Tumor Shrinkage as Predictive Biomarkers in Unresectable Hepatocellular Carcinoma Patients Treated With Lenvatinib, PD-1 Inhibitors, in Combination With TACE

Purpose: The purpose of this prospective observational study was to investigate the relationship between pretreatment neutrophil-to-lymphocyte ratio (NLR) and posttreatment early tumor shrinkage (ETS), and clinical outcomes in patients with unresectable hepatocellular carcinoma (uHCC) who received lenvatinib, programmed death-1 inhibitors plus transcatheter arterial chemoembolization. Patients and Methods: A total of 63 uHCC patients were treated with this triple combination. Multivariate analyses to determine the independent factors associated with overall survival (OS) were employed. The link between NLR and clinical results was further analyzed. Furthermore, the predictive value of combining NLR with ETS should be investigated to stratify patients receiving treatment for survival benefits. Results: Progression-free survival and OS were 9.8 and 23.0 months, respectively, with a median follow-up of 20.8 months. On a multivariate analysis of OS, NLR was the only independent prognostic factor. Patients with NLR low (NLR < 3.2) had longer progression-free survival (19.3 vs 7.3 months, P < 0.001) and OS (28.9 vs 16.9 months, P < 0.001), higher objective response rate (86.7% vs 39.4%, P < 0.001), and a higher chance of achieving ETS ≥ 10% (ETS high) (73.3% vs 21.1%, P < 0.001) compared with patients with NLR high (NLR ≥ 3.2). The Spearman correlation analysis also showed the strong consistency between NLR and ETS (R2 = 0.6751). In the subgroup analysis, greater OS benefit was found in the NLR low/ETS high group than the NLR high/ETS low group (χ2 = 31.258, P < 0.001), while there was no survival difference for patients in the NLR low/ETS low group compared with in the NLR high/ETS high group (χ2 = 0.046, P = 0.830). Conclusion: NLR has the potential to identify which patients would benefit from this triple therapy, and when combined with ETS, it has the potential to provide greater predictive power in selecting the appropriate candidates for this combination treatment.

Five years of lenvatinib in hepatocellular carcinoma: are there any predictive and/or prognostic factors?

INTRODUCTION

Lenvatinib was the first drug approved in 2017 for first-line treatment of hepatocarcinoma (HCC) after 10 years of Sorafenib as exclusive standard of care. The therapeutic armamentarium has recently expanded following the approval of atezolizumab plus bevacizumab.

AREAS COVERED

Numerous studies have been conducted during the past 5 years on Lenvatinib use in real-world settings in an effort to determine prognostic and predictive factors of Lenvatinib efficacy. In order to choose the most effective therapeutic approach, it may be helpful to summarize these results in this review.

EXPERT OPINION

A subgroup that appears to benefit most from Lenvatinib therapy are patients with non-viral cirrhosis. This aspect is of great importance today considering the increase in NASH prevalence. Also, a significant proportion of BCLC B patients appear to respond well to Lenvatinib therapy. The biological heterogeneity highlighted in HCC patients, along with the growing number of therapeutic options, makes the identification of stratification tools able to define which patients are more likely to respond to a treatment rather than another one of crucial interest. Further investigation deepening the biological pathways underlying HCC carcinogenesis are of particular interest in order to pave the way for precision medicine even for HCC patients.

Inflammation-based prognostic scoring system for predicting the prognosis of advanced small cell lung cancer patients receiving anlotinib monotherapy

BACKGROUND

According to the randomized multicenter phase II trial (ALTER1202), anlotinib has been approved as a third-line therapy for advanced small-cell lung cancer (SCLC). Some studies showed the predictive function of inflammatory markers, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) in the different cancers treated with anti-vascular targeting drugs. However, none of the studies showed the roles of NLR, PLR, and LMR in SCLC patients receiving anlotinib. Thus, our objective was to establish a scoring system based on inflammation to individuate patient stratification and selection based on NLR, PLR, and LMR.

METHODS

NLR, PLR, and LMR and their variations were calculated in 53 advanced SCLC patients receiving anlotinib as a third- or further-line treatment at Ningbo Medical Center Lihuili Hospital between January 2019 and December 2021. Kaplan-Meier curves were plotted. Both univariate and multivariate Cox regressions were used to identify predictors of survival.

RESULTS

Disease control rate was related to pre-NLR, pre-PLR, pre-LMR, post-NLR elevation, post-PLR elevation, and post-LMR elevation. The multivariate analysis determined post-NLR elevation, pre-PLR > 240.56, and pre-LMR ≤1.61 to be independently associated with progression-free survival, not overall survival. The inflammation-based prognostic scoring system demonstrated favorable predictive ability from the receiver operating characteristic curve (AUC: 0.791, 95% CI: 0.645-0.938).

CONCLUSIONS

Post-NLR variation, pre-PLR, and pre-LMR were independent prognostic factors for PFS in advanced SCLC receiving anlotinib monotherapy. The inflammation-based prognostic scoring system can accurately predict effectiveness and survival.

Glasgow prognostic score predicts survival in patients with unresectable hepatocellular carcinoma treated with lenvatinib: a multicenter analysis

OBJECTIVE

The use of Glasgow prognostic score (GPS), calculated using the serum C-reactive protein and albumin levels, to predict the outcomes of patients with unresectable hepatocellular carcinoma (HCC) treated with lenvatinib was investigated in this study.

METHODS

A total of 508 patients with Child-Pugh class A HCC treated with lenvatinib were included in this study.

RESULTS

The median overall and progression-free survivals were 20.4 months [95% confidence interval (CI), 17.7-23.2 months] and 7.5 months (95% CI, 6.8-8.5 months), respectively. The median overall survivals of patients with a GPS of 0, 1, and 2 were 28.5, 16.0, and 9.1 months, respectively (P < 0.001). When adjusted for age, sex, performance status, etiology, α-fetoprotein, macroscopic vascular invasion, extrahepatic spread, history of sorafenib therapy, and GPS, a GPS of 1 [hazard ratio (HR), 1.664; 95% CI, 1.258-2.201; P < 0.001] and a GPS of 2 (HR, 2.664; 95% CI, 1.861-3.813; P < 0.001) were found to be independently associated with overall survival. The median progression-free survivals of patients with a GPS of 0, 1, and 2 were 8.8, 6.8, and 3.8 months, respectively (P < 0.001). When adjusted for the same factors of overall survival, a GPS of 2 (HR, 2.010; 95% CI, 1.452-2.784; P < 0.001) was found to be independently associated with progression-free survival. As the albumin-bilirubin with tumor node metastasis score increased, the proportion of patients with a GPS of 1 or 2 increased (P < 0.001).

CONCLUSIONS

GPS can be used to predict survival in patients with unresectable HCC who were treated with lenvatinib.

Comparison of the prognostic effect of sarcopenia on atezolizumab plus bevacizumab and lenvatinib therapy in hepatocellular carcinoma patients

Background and Aim

Sarcopenia has received much attention as a poor prognostic factor in various fields, and has also been reported to worsen prognosis in patients with hepatocellular carcinoma (HCC) treated with sorafenib or lenvatinib (LEN). Atezolizumab/bevacizumab (ATZ/BEV) is recommended as first‐line drug therapy for unresectable‐HCC, but the effect of sarcopenia on patients treated with ATZ/BEV is unknown.

Methods

We enrolled 98 patients treated with ATZ/BEV or LEN. Computed tomography performed before the initiation of drug therapy was used to diagnose sarcopenia in accordance with the criteria proposed by the Japanese Society of Hepatology. Patients were divided into two groups based on the presence or absence of sarcopenia in each regimen, and patient characteristics, adverse events, and prognosis were compared.

Results

In ATZ/BEV therapy, 57.1% of patients had sarcopenia. The sarcopenia group had significantly more women (P = 0.0125) and more macroscopic vascular invasion (P = 0.0270). Sarcopenia had no significant effect on progression‐free survival (PFS) and overall survival (OS). In LEN therapy, 63.4% of patients had sarcopenia. The sarcopenia group was significantly older (P = 0.0064) and had a higher number of women (P = 0.0003), a higher neutrophil–lymphocyte ratio (P = 0.0222), worse albumin–bilirubin grade (P = 0.0087), and worse best response (P = 0.0255). PFS (P = 0.0091) and OS (P = 0.0006) were worse in the sarcopenia group. In multivariate analysis, age (P = 0.0362), lymphocyte–monocyte ratio (P = 0.0365), and sarcopenia (P = 0.0268) were independent prognostic factors for OS.

Conclusion

In ATZ/BEV therapy, sarcopenia does not determine prognosis, and therapeutic efficacy can be expected even in cases of sarcopenia.

Neutrophil-lymphocyte ratio predicts early outcomes in patients with unresectable hepatocellular carcinoma treated with atezolizumab plus bevacizumab: a multicenter analysis

OBJECTIVE

To investigate whether neutrophil-to-lymphocyte ratio (NLR) can predict outcomes in patients with unresectable hepatocellular carcinoma (HCC) treated with atezolizumab plus bevacizumab (Atez/Bev).

METHODS

A total of 249 patients with unresectable HCC treated with Atez/Bev were included. We analyzed survival and discontinuation of this therapy in this cohort.

RESULTS

Cumulative overall survival at 2, 4, 6, and 8 months was 97.6%, 94.9%, 88.9%, and 82.8%, respectively. Cumulative overall survival differed significantly between patients with low (<3.0) versus high (≥3.0) NLR (P = 0.001). Conversely, cumulative progression-free survival did not differ between patients with low versus high NLR. The distribution of response was 1.5% for complete response, 17.1% for partial response, 60.5% for stable disease, and 21.0% for progressive disease. Responses were not different between patients with low and high NLR. Regarding adverse events, immune-related liver injury of any grade and grade of at least 3, decreased appetite of any grade, grade of at least 3 proteinuria, and other adverse events of any grade differed significantly between patients with low and high NLR. There were 56, 18, and 2 patients who discontinued Atez/Bev therapy due to progression of disease, adverse event, and other reasons, respectively. The cumulative discontinuation rate for Atez/Bev therapy due to adverse events differed significantly between patients with low versus high NLR (P = 0.022). Cox proportional hazards modeling analysis with inverse probability weighting showed that NLR of at least 3.0 was significantly associated with overall survival (hazard ratio, 3.369; 95% confidence interval, 1.024-11.080).

CONCLUSIONS

NLR can predict outcomes in patients with unresectable HCC treated with Atez/Bev.

C-reactive protein to albumin ratio predicts survival in patients with unresectable hepatocellular carcinoma treated with lenvatinib

We investigated the impact of C-reactive protein to albumin ratio (CAR) on predicting outcomes in 522 patients with unresectable hepatocellular carcinoma (HCC) treated with lenvatinib. We determined the optimal CAR cutoff value with time-dependent receiver operating characteristic curve analysis. Additionally, we clarified the relationship between CAR and liver function or HCC progression. Median overall survival was 20.0 (95% confidence interval (CI), 17.2-22.6) months. The optimal CAR cutoff value was determined to be 0.108. Multivariate analysis showed that high CAR (≥ 0.108) (hazard ratio (HR), 1.915; 95% CI, 1.495-2.452), Eastern Cooperative Oncology Group performance status ≥ 1 (HR, 1.429), and α-fetoprotein ≥ 400 ng/mL (HR, 1.604) were independently associated with overall survival. Cumulative overall survival differed significantly between patients with low versus high CAR (p < 0.001). Median progression-free survival was 7.5 (95% CI, 6.7-8.1) months. Multivariate analysis showed that age, CAR ≥ 0.108 (HR, 1.644; 95% CI, 1.324-2.043), and non-hepatitis B, non-hepatitis C etiology (HR, 0.726) were independently associated with progression-free survival. Cumulative progression-free survival differed significantly between patients with low versus high CAR (p < 0.001). CAR values were significantly higher as Japan Integrated Staging score increased (p < 0.001). In conclusion, CAR can predict outcomes in patients with unresectable HCC treated with lenvatinib.

The importance of liver functional reserve in the non-surgical treatment of hepatocellular carcinoma

The aim of any oncological treatment is not just to eliminate the tumour, but to maximise patient survival and quality of life. Since the liver has a vital function, any radical treatment that severely compromises liver function will result in a shortening of life expectancy, rather than a prolongation. Furthermore, even non-severe liver damage may prevent the delivery of further effective therapies. This is particularly important in the case of hepatocellular carcinoma (HCC), as it is associated with underlying cirrhosis in most patients - cirrhosis itself is not only a potentially lethal disease and independent prognostic factor in HCC, but it also makes liver function fragile. Accordingly, some information about liver dysfunction is included in most staging systems for HCC and can be used to guide the selection of treatments that the functional liver reserve can tolerate. Unfortunately, the prediction of functional damage to the liver in the case of antitumor treatments is very challenging and still suboptimal in any given patient. Moreover, while the assessment of functional reserve can now be used to avoid postoperative liver failure in the surgical setting, its use has been less well clarified for non-surgical therapies, which is of particular relevance today, as several lines of effective non-surgical treatments, including systemic therapies, have become available. The present article will a) critically review the implications of the assessment of liver functional reserve in patients with HCC, b) illustrate the available tools to assess liver functional reserve and c) discuss the role of functional assessment for each type of non-surgical therapy for HCC.

The Prognostic Role of Circulating FPR Before Operation in Patients with BCLC A-C Hepatocellular Carcinoma: A Retrospective Cohort Study

Background

This research aimed to comprehensively assess the prognostic role of fibrinogen to prealbumin ratio (FPR) in BCLC A-C HCC patients treated by TACE and RFA.

Methods

The research included 240 patients at stage BCLC A-C treated by TACE and RFA at Beijing Ditan Hospital of Capital Medical University from May 2011 to November 2018.

Results

The results showed that the size of the tumor, vascular invasion, α-foetoprotein, cirrhosis, NLR, LMR, and PLR showed prognostic value in predicting 5-year OS. Besides, FPR (95% confidence interval: 1.006–1.013, hazard ratio: 1.009) was a prognostic factor for the prediction of 5-year OS in HCC.

Conclusion

Our research indicated that FPR was a potential indicator for patients with BCLC A-C hepatocellular carcinoma after treatment of RFA and TACE.

Efficacy and Safety of TACE Combined With Lenvatinib Plus PD-1 Inhibitors Compared With TACE Alone for Unresectable Hepatocellular Carcinoma Patients: A Prospective Cohort Study

Purpose

To compare the efficacy and safety of the combination of transcatheter arterial chemoembolization (TACE), Lenvatinib, and programmed cell death protein-1 (PD-1) inhibitors (combination group) with TACE (TACE group) in the treatment of patients with unresectable hepatocellular carcinoma (uHCC).

Methods

We consecutively enrolled 110 patients with uHCC in this prospective cohort study, with 56 patients receiving combination treatment and 54 patients receiving TACE from November 2017 to September 2020. The differences in tumor response, survival benefit, and adverse events (AEs) were compared between the two groups. Factors affecting survival were identified via Cox regression analysis.

Results

Compared with the TACE group, the combination group had a higher objective response rate (ORR) (67.9% vs. 29.6%, p < 0.001), longer median progression-free survival (mPFS) (11.9 vs. 6.9 months, P = 0.003) and overall survival (mOS) (23.9 vs. 15.3 months, p < 0.001). Multivariate analysis showed that the neutrophil-to-lymphocyte ratio (NLR) and the treatment option were independent factors associated with the PFS and OS. Further subgroup analysis showed that patients with low NLR (≤median 3.11) receiving combination therapy had better mPFS (20.1 vs. 6.2 months, P < 0.001) and mOS (28.9 vs. 15.2 months, P < 0.001) than those receiving TACE, while no obvious difference in PFS or OS was observed between the two groups in patients with high NLR (> 3.11). There were no unexpected toxicities in the combination group.

Conclusion

Compared with TACE, the combination treatment demonstrated an improved clinical efficacy and manageable safety profile in patients with uHCC. Combination treatment showed better therapeutic efficacy in patients with low NLR; therefore, this ratio could be used to identify patients who will benefit from this treatment.

Neutrophil-to-Lymphocyte Ratio, Platelet-to-Lymphocyte Ratio, and Their Variations as a Basis for a Prediction Model in Advanced NSCLC Patients Receiving Anlotinib

Background

A phase III randomized multicenter trial (ALTER0303) reported anlotinib to be significantly beneficial to patient survival. An array of inflammatory biomarkers, such as neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR), are associated with the response to treatment in numerous types of cancer. However, we found few studies investigating the predictive value of NLR or PLR in advanced NSCLC treatment with anlotinib. Thus, our objective was to examine the relationship between NLR and PLR and treatment effect, as well as to individuate patient stratification and selection.

Methods

NLR and PLR as well as their variations were calculated in 152 advanced NSCLC patients receiving anlotinib as a third or further-line treatment at Ningbo Medical Center Lihuili Hospital between July 2018 and December 2020. The best cut-off values of NLR and PLR for predicting the treatment response were selected. Survival curves were plotted using the Kaplan–Meier method, while univariable and multivariable Cox regression were used to identify and determine dependent and independent predictors of survival.

Results

, Low disease control rate (DCR) was related with a high pre-NLR (P = 0.007), high pre-PLR (P = 0.004), and elevated post-NLR (P = 0.010). Multivariate analysis determined high pre-PLR (>205.63) and elevated post-NLR to be independently associated with poor PFS or OS. Patients whose risk score was 2 resulting from the prediction model based on pre-PLR and post-NLR had a 4.52 times higher risk of death compared to patients whose risk score was 0 (HR: 4.516, 95% CI: 2.502-8.152, P ≤ 0.001).

Conclusions

Pre-PLR and post-NLR were independent prognostic indicators in patients with advanced NSCLC receiving anlotinib as a third or further-line treatment. Patients whose risk value score was 0 had a higher therapy effectiveness and better survival.

Safety and efficacy of atezolizumab plus bevacizumab in patients with unresectable hepatocellular carcinoma in early clinical practice: A multicenter analysis

PURPOSE

To assess the impact of clinical factors on the safety and efficacy of atezolizumab plus bevacizumab (ATZ + BV) treatment in patients with unresectable hepatocellular carcinoma (u-HCC).

METHOD

Ninety-four u-HCC patients who were treated with ATZ + BV at multiple centers were enrolled. We defined Child-Pugh (CP)-A patients who received ATZ + BV treatment as a first line therapy as the 'meets the broad sense of the IMbrave150 criteria' group (B-IMbrave150-in, n = 46), and patients who received ATZ + BV treatment as a later line therapy or CP-B patients (regardless of whether ATZ + BV was a first line or later line therapy) as the B-IMbrave150-out group (n = 48). Patients were retrospectively analyzed for adverse events (AEs) and treatment outcomes according to their clinical characteristics, including neutrophil lymphocyte ratio (NLR) at baseline.

RESULTS

The overall incidence of AEs was 87.2% (82/94 patients). The frequency of interruption of ATZ + BV treatment due to fatigue was higher in CP-B than CP-A patients (p = 0.030). Objective response (OR) rates of the B-IMbrave150-in group (28.3%, 39.1%) were significantly higher than those of the B-IMbrave150-out group (8.3%, 18.8%; p = 0.0157, 0.0401) using Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST, respectively. In multivariate analysis, NLR (hazard ratio (HR), 4.591; p = 0.0160) and B-IMbrave150 criteria (HR, 4.108; p = 0.0261) were independent factors associated with the OR of ATZ + BV treatment using RECIST.

CONCLUSION

In real-world practice, ATZ + BV treatment might offer significant benefits in patients who meet B-IMbrave150 criteria or have low NLR.

Prognostic significance of sarcopenia in patients with hepatocellular carcinoma treated with lenvatinib: A retrospective analysis

Our study investigated the correlation between sarcopenia and clinical outcomes in patients with hepatocellular carcinoma (HCC) treated with lenvatinib. We retrospectively evaluated 40 consecutive patients with unresectable HCC receiving lenvatinib between November 2018 and May 2020 at the First Hospital of Jilin University. Skeletal muscle mass was measured before treatment initiation. Prognostic significance was assessed with univariate and multivariate Cox proportional hazards models. Overall survival (OS) and progression-free survival (PFS) were evaluated for patients with and without sarcopenia. Sarcopenia was present in 23/40 patients (57.5%). After a median follow-up of 9.2 months, patients with sarcopenia had significantly worse OS and PFS compared with those without sarcopenia (OS: 8.4 months [m] vs 14.7 m, P = .02; PFS: 4.2 m vs 9.0 m, P = .04). Multivariate Cox proportional hazards models identified presence of sarcopenia as an independent risk factor for shorter OS (hazard ratio [HR], 0.257; 95% confidence interval [CI], 0.083-0.794; P = .02). In subgroup analysis, sarcopenia was associated with worse survival than non-sarcopenic patients, irrespective of age, Barcelona clinic liver cancer stage, or albumin-bilirubin grade. Our results show sarcopenia may be a predictor of poor prognosis in patients with HCC receiving lenvatinib. Management of sarcopenia is a vital factor for improving survival outcomes in patients with HCC.

Inflammation and Myeloid Cells in Cancer Progression and Metastasis

To date, the most immunotherapy drugs act upon T cell surface proteins to promote tumoricidal T cell activity. However, this approach has to date been unsuccessful in certain solid tumor types including pancreatic, prostate cancer and glioblastoma. Myeloid-related innate immunity can promote tumor progression through direct and indirect effects on T cell activity; improved understanding of this field may provide another therapeutic avenue for patients with these tumors. Myeloid cells can differentiate into both pro-inflammatory and anti-inflammatory mature form depending upon the microenvironment. Most cancer type exhibit oncogenic activating point mutations (ex. P53 and KRAS) that trigger cytokines production. In addition, tumor environment (ex. Collagen, Hypoxia, and adenosine) also regulated inflammatory signaling cascade. Both the intrinsic and extrinsic factor driving the tumor immune microenvironment and regulating the differentiation and function of myeloid cells, T cells activity and tumor progression. In this review, we will discuss the relationship between cancer cells and myeloid cells-mediated tumor immune microenvironment to promote cancer progression and immunotherapeutic resistance. Furthermore, we will describe how cytokines and chemokines produced by cancer cells influence myeloid cells within immunosuppressive environment. Finally, we will comment on the development of immunotherapeutic strategies with respect to myeloid-related innate immunity.

The Prognostic Value of Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio in Patients with Hepatocellular Carcinoma Receiving Atezolizumab Plus Bevacizumab

Atezolizumab plus bevacizumab has been approved as the first-line systemic treatment for patients with unresectable hepatocellular carcinoma (uHCC). This study was designed to assess the clinical impact of atezolizumab plus bevacizumab in uHCC patients. A total of 48 uHCC patients receiving atezolizumab plus bevacizumab were identified, including first-line, second-line, third-line, and later-line settings. In these patients, the median progression-free survival (PFS) was 5.0 months, including 5.0 months for the first-line treatment, not reached for the second-line treatment, and 2.5 months for the third line and later line treatment. The objective response rate and disease control rate to atezolizumab plus bevacizumab were 27.1% and 68.8%, respectively. The severity of most adverse events was predominantly grade 1-2, and most patients tolerated the toxicities. The ratios of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte (PLR) were used to predict PFS in these patients. The optimal cutoff values of NLR and PLR were 3 and 230, and NLR and PLR were independent prognostic factors for superior PFS in the univariate and multivariate analyses. Our study confirms the efficacy and safety of atezolizumab plus bevacizumab in uHCC patients in clinical practice and demonstrates the prognostic role of NLR and PLR for PFS in these patients.

Usefulness of neutrophil-to-lymphocyte ratio (NLR) as a prognostic predictor after treatment of hepatocellular carcinoma." Review article

The neutrophil-to-lymphocyte ratio (NLR) is an inflammatory marker which has been investigated as a prognostic indicator in post-therapeutic recurrence and survival of patients with HCC. Our aim was to review all studies that assessed the prognostic value of pre-treatment NLR in predicting patient survival, cancer recurrence, and graft survival in patients undergoing various therapies for HCC. We searched the database of PubMed and Google Scholar to review all studies that have the word "NLR" and the word "HCC." We included all studies that assessed pre-treatment NLR as a prognostic factor in predicting outcomes in HCC patients. We excluded studies that assessed the correlation between post-treatment NLR or dynamic changes in NLR after treatment and HCC outcomes in an effort to minimize the confounding effect of each treatment on NLR. We reviewed 123 studies that studied the correlation between pre-treatment NLR and patient survival, 72 studies that evaluated the correlation between pre-treatment NLR and tumor recurrence, 21 studies that evaluated the correlation between NLR and tumor behavior, and 4 studies that assessed the correlation between NLR and graft survival. We found a remarkable heterogeneity between the methods of the studies, which is likely responsible for the differences in outcomes. The majority of the studies suggested a correlation between higher levels of pre-treatment NLR and poor outcomes. We concluded that NLR is a reliable and inexpensive biomarker and should be incorporated into other prognostic models to help determine outcomes following HCC treatment.

Neutrophils: Driving inflammation during the development of hepatocellular carcinoma

The relationship between immune and inflammatory responses in hepatocellular carcinoma (HCC) has garnered significant interest. In the peripheral blood and tumour microenvironment (TME), neutrophils, which are innate immune cells, crucially respond to various inflammatory factors, leading to tumour progression. To some extent, they affect the clinical treatment strategy and survival among HCC patients. A high circulating neutrophil-to-lymphocyte ratio is a reliable factor that can be used to predict poor outcomes in HCC patients. However, the mechanisms underlying the protumoural effects of circulating neutrophils remain poorly understood. Besides, the distinct role and function of neutrophils at the site of HCC remain relatively unclear, which is partially attributed to their substantial heterogeneity compared with other immune cells. In this review, we firstly discuss the current information available, detailing distinct subsets, functional phenotypes, and the impact of circulating and tumour-infiltrating neutrophils on tumourigenesis in HCC. Furthermore, we describe recent pre-clinical and clinical studies concerning neutrophils for evaluating the feasibility of targeting diverse protumoural aspects to improve therapeutic efficacy, thus paving the way for neutrophil-based treatment, especially in combination with immunotherapy.

Prediction and Risk Factors for Prognosis of Cirrhotic Patients with Hepatic Encephalopathy

Background and Aims

Hepatic encephalopathy (HE) is characterized by recurrence and poor quality of life. Acute-on-chronic liver failure (ACLF) mainly occurs in patients with chronic liver diseases and often presents with HE. Several predictive models have been proposed to predict the outcomes of these patients. Our study is aimed at identifying associated risk factors and the prognostic accuracies of predictive models in HE patients with or without ACLF.

Methods

Patients with liver cirrhosis were retrospectively enrolled. Risk factors were evaluated by multivariate regression analyses. The predictive capabilities of models were calculated using the receiver operating characteristic (ROC) curve analyses and compared by the DeLong tests. Outcomes were defined as in-hospital mortality, HE severity, and ACLF occurrence.

Results

In multivariate regression analyses, serum biomarkers neutrophil and total bilirubin (TBIL) were independently correlated with in-hospital death. Alanine aminotransferase (ALT) and blood urea nitrogen (BUN) were independent serum biomarkers associated with HE severity. Hemoglobin, TBIL, BUN, and international normalized ratio (INR) were significant indicators associated with ACLF incidence. For prediction of in-hospital mortality, Child-Pugh was superior to the others in the whole patients, while NLR showed the best capability in the ACLF group.

Conclusion

In cirrhotic patients present with HE, BUN is a risk factor associated with HE severity and ACLF incidence. Child-Pugh and NLR scores may be effective prognosticators in patients with HE.

Kinetics of the neutrophil-lymphocyte ratio during PD-1 inhibition as a prognostic factor in advanced hepatocellular carcinoma

BACKGROUND AND AIMS

Programmed death 1 (PD-1) inhibitors have improved survival outcomes and produced durable responses in advanced hepatocellular carcinoma (HCC) for some patients. Here, we evaluated the relationship between the baseline and kinetics of the neutrophil-lymphocyte ratio (NLR) and clinical outcomes in nivolumab-treated HCC patients.

METHODS

All consecutive HCC patients treated with nivolumab between July 2017 and June 2020 were screened for the eligibility. The NLRs were calculated before and at 2, 4 and 6 weeks after treatment. Survival outcomes were compared based on the baseline and kinetics of NLR. We additionally analysed the association of the baseline and dynamic changes in the NLR with hyperprogression (HPD).

RESULTS

Among the 194 included cases, most patients were male (82.0%) and had a Child-Pugh Class A disease (70.6%). Patients with a baseline NLR ≥ 3 (hazard ratio [HR] 2.46; 95% CI 1.63-3.71) had a poorer overall survival than patients with baseline NLR < 3. During the treatment, the NLR increased rapidly in patients developing HPD, and only a ΔNLR at 4 weeks was predictive of HPD. The risk of HPD increased by 20% for every 20% increase in the ΔNLR at 4 weeks. Accordingly, an NLR increase at 4 weeks (HR 1.79; 95% CI 1.19-2.68) was associated with an increased risk of death, especially among patients with a baseline NLR ≥ 3.

CONCLUSIONS

The baseline and on-treatment kinetics for the NLR are effective prognostic indicators in nivolumab-treated patients with HCC. This may help to guide patient selection and on-treatment strategies for immunotherapies in advanced HCC.

Impact of modified albumin-bilirubin grade on survival in patients with HCC who received lenvatinib

We investigated the impact on survival of modified albumin-bilirubin (mALBI) grade versus Child-Pugh classification in patients with hepatocellular carcinoma (HCC) who received lenvatinib. A total of 524 patients with HCC who received lenvatinib were included. Univariate analysis showed that mALBI grade 2b/3 and Child-Pugh class B/C were significantly associated with survival [hazard ratio (HR), 2.471; 95% confidence interval (CI), 1.944-3.141 and HR, 2.178; 95%CI, 1.591-2.982]. In patients with a Child-Pugh score of 5, multivariate analysis showed that mALBI grade 2b/3 was independently associated with survival (HR, 1.814; 95%CI, 1.083-3.037). Conversely, among patients with mALBI grade 1/2a, there was no difference in survival between those with a Child-Pugh class of 5 or 6 (p = 0.735). Time-dependent receiver operating characteristic analysis showed that the ALBI score predicted survival better than the Child-Pugh score. The optimal cut-off value of the ALBI score for predicting survival was nearly the same as the value separating mALBI grades 2a and 2b. In conclusion, the mALBI grade was a better predictor of survival than the Child-Pugh classification in patients with unresectable HCC who received lenvatinib therapy.

Trial eligibility in advanced hepatocellular carcinoma: Does it support clinical practice in underrepresented subgroups?

Although hepatocellular carcinoma is considered a highly lethal malignancy, recent therapeutic advances have been achieved during the last 10 years. This scenario resulted in an unprecedented improvement in survival for patients with advanced hepatocellular carcinoma, almost reaching 20-26 mo of overall survival after first-second line sequential treatment. The advent of the combination of atezolizumab with bevacizumab showed, for the first time, superiority over sorafenib with improvement in overall survival. However, first and second-line trials were correctly based on the premise that a strict selection of patients enhances the power to capture the positive effect of treatment by excluding competing risks for mortality such as liver failure, decompensated cirrhosis or other underlying medical conditions. As a result, the inclusion criteria used in clinical trials do not support the use of novel therapies in several real-world scenarios involving underrepresented subgroups, such as patients with unpreserved liver function, other comorbid conditions, a history of solid-organ transplantation, autoimmune disorders and those with a high risk of bleeding. The present text aims at discussing treatment strategies in these subgroups.

Real-world clinical outcomes of sofosbuvir and velpatasvir treatment in HCV genotype 1- and 2-infected patients with decompensated cirrhosis: A nationwide multicenter study by the Japanese Red Cross Liver Study Group

The real-world virological efficacy and safety of interferon-free direct-acting antiviral (DAA) therapy with sofosbuvir (SOF) and velpatasvir (VEL) were assessed in hepatitis C virus (HCV) genotype 1- and 2-infected patients with decompensated cirrhosis. A total of 65 patients with HCV-related decompensated cirrhosis (Child-Pugh score of 7 points or more) who were treated with the SOF/VEL regimen were enrolled. The sustained virological response (SVR) rate and safety profile were analyzed. SVR was defined as undetectable serum HCV RNA at 12 weeks after the end of treatment (SVR12). The percentages of patients with undetectable HCV RNA at 4, 8, and 12 weeks after the start of therapy were 81.2% (95% confidence interval [CI], 69.5-89.9) (52/64), 98.4% (95% CI, 91.2-100.0) (60/61), and 98.5% (95% CI, 91.7-100.0) (64/65), respectively. The overall SVR rate was 92.3% (95% CI, 83.0-97.5) (60/65). Albumin-bilirubin (ALBI) scores decreased during and after treatment (p < 0.001), and there were significant differences between baseline and end of treatment and between baseline and SVR12. Subgroup analyses showed no significant differences in SVR rates according to patient age, sex, HCV genotype (subtype), Child-Pugh classification, modified ALBI grade, presence of ascites, presence of hepatic coma, or history of hepatocellular carcinoma. In all subpopulations, the SVR rates were higher than 80%. There were no severe adverse events associated with the treatment. The SOF/VEL regimen showed good virological efficacy and acceptable safety even in patients with HCV-related decompensated cirrhosis.

Analysis of efficacy of lenvatinib treatment in highly advanced hepatocellular carcinoma with tumor thrombus in the main trunk of the portal vein or tumor with more than 50% liver occupation: A multicenter analysis

AIMS

To assess the safety, efficacy, and prognostic impact of clinical factors associated with lenvatinib treatment in highly advanced hepatocellular carcinoma (HCC) with tumor thrombus in the main portal vein trunk (VP4) or tumor with more than 50% liver occupation (tm50%LO).

METHODS

A total of 61 highly advanced HCC patients (41 patients with tm50%LO and 20 patients with VP4) who were treated with lenvatinib at multicenter were enrolled and retrospectively analyzed for treatment outcomes according to their clinical status, including tumor morphology.

RESULTS

The most frequent grade ≥3 adverse event in tm50%LO HCC was elevated aspartate aminotransferase (17.1%). Objective response rates were 37.5% and 0% in tm50%LO HCC patients with Child-Pugh grade (CP)-A and CP-B, respectively, and 26.7% and 0% in VP4 HCC patients with CP-A and CP-B, respectively. Estimated median progression-free survival and overall survival were 132 days and 229 days, and 101 days and 201 days in patients with tm50%LO and VP4, respectively. In multivariate analysis, modified albumin-bilirubin grade (hazard ratio 0.372, 95% CI 0.157-0.887; p = 0.0241) and tumor morphology (hazard ratio 0.322, 95% CI 0.116-0.889; p = 0.0287) were independently associated with progression-free survival in patients with tm50%LO HCC. In VP4 HCC, median progression-free survival was worse in CP-B (57 days) than in CP-A patients (137 days, p = 0.0462).

CONCLUSIONS

Lenvatinib treatment offers a benefit in highly advanced HCC (tm50%LO or VP4) patients with good liver function or nodular-type tumor. The various characteristics identified in this study might be useful as indicators of lenvatinib treatment in highly advanced HCC with tm50%LO or VP4, which are considered very refractory cancers.

Lenvatinib for Hepatocellular Carcinoma: A Literature Review

Lenvatinib, which is an oral multikinase inhibitor, showed non-inferiority to the sorafenib in terms of overall survival (OS) and a higher objective response rate (ORR) and better progression-free survival (PFS) in patients with hepatocellular carcinoma (HCC). A good liver function and Barcelona Clinic Liver Cancer (BCLC) intermediate stage were the key factors in achieving therapeutic efficacy. The management of adverse events plays an important role in continuing lenvatinib treatment. While sequential therapies contributed to prolonging overall survival, effective molecular targeted agents for the administration after lenvatinib have not been established. Repeated transcatheter arterial chemoembolization (TACE) was associated with a decline in the liver function and poor therapeutic response in BCLC intermediate patients. Recently, the Asia-Pacific Primary Liver Cancer Expert (APPLE) Consensus Statement proposed the criteria for TACE unsuitability. Upfront systemic therapy may be better for the BCLC intermediate stage HCC patients with a high tumor burden, while selective TACE will be recommended for obtaining a curative response in patients with a low tumor burden. This article reviews the therapeutic response, management of adverse events, post-progression treatment after Lenvatinib, and treatment strategy for BCLC intermediate stage HCC.

Impact of Early Lenvatinib Administration on Survival in Patients with Intermediate-Stage Hepatocellular Carcinoma: A Multicenter, Inverse Probability Weighting Analysis

AIM/BACKGROUND

Transarterial chemoembolization (TACE) is recommended for patients with intermediate-stage hepatocellular carcinoma (HCC). In this study, we investigated the impact of early lenvatinib administration in patients with intermediate-stage HCC, especially those with tumors beyond the up-to-7 criteria.

MATERIALS/METHODS

A total of 208 patients with intermediate-stage HCC whose initial treatment was early lenvatinib administration or TACE were enrolled. Multivariate overall survival analysis was performed in this cohort. In addition, the impact of early lenvatinib administration on survival in patients with HCC beyond the up-to-7 criteria was clarified using inverse probability weighting (IPW) analysis.

RESULTS

The overall cumulative survival rates at 6, 12, 18, and 24 months were 94.4, 79.9, 65.8, and 50.1%, respectively. Multivariate analysis with Cox proportional hazards modeling showed that HCC treatment with lenvatinib (hazard ratio [HR], 0.199; 95% confidence interval [CI], 0.077-0.517; p < 0.001), α-fetoprotein ≥100 ng/mL (HR, 1.687), Child-Pugh class B disease (HR, 1.825), and beyond the up-to-7 criteria (HR, 2.016) were independently associated with overall survival. The 6-, 12-, 18-, and 24-month cumulative survival rates were 96.0, 90.4, 65.7, and 65.7%, respectively, in patients treated with lenvatinib, and 94.1, 78.5, 65.3, and 48.4%, respectively, in patients who received TACE (p < 0.001). In addition, univariate analysis with Cox proportional hazards modeling adjusted by IPW showed that lenvatinib therapy was significantly associated with overall survival in patients with HCC beyond the up-to-7 criteria (HR, 0.230; 95% CI, 0.059-0.904; p = 0.035).

CONCLUSIONS

Lenvatinib may be a suitable first-line treatment for patients with intermediate-stage HCC beyond the up-to-7 criteria.

Early radiological response evaluation with response evaluation criteria in solid tumors 1.1 stratifies survival in hepatocellular carcinoma patients treated with lenvatinib

Background and Aim

Lenvatinib (LEN) has an antitumor effect with an early reduction in contrast enhancement for unresectable hepatocellular carcinoma (HCC). The aim of this study was to reveal the most useful radiological response evaluation for overall survival (OS) in patients treated with LEN.

Methods

Patients receiving LEN therapy (n = 80) were retrospectively recruited from April 2018 to January 2020. Enhanced computed tomography scans were performed at baseline and every 4-8 weeks. OS and radiological response were evaluated using response evaluation criteria in solid tumors (RECIST 1.1), modified RECIST (mRECIST), and Choi criteria. To be eligible for study, a minimal cumulative duration of LEN was 4 weeks. A total of 62 patients were included in the analysis.

Results

The median OS was 469 days. The RECIST 1.1, mRECIST, and Choi criteria identified 14 (22.5%), 30 (48.3%), and 33 (53.2%) patients with an objective response, respectively. In the univariate analysis, Child-Pugh class B, major vascular invasion, and high alpha-fetoprotein (>200) were statistically significant poor prognostic factors. Radiological response was a significantly better prognostic factor in each criterion (RECIST, mRECIST, and Choi). In the multivariate analysis, radiological response evaluated by RECIST (hazard ratio, 0.259; 95% confidence interval, 0.0723-0.928; P = 0.038) was an independent factor. Furthermore, only RECIST significantly stratified prognosis (P = 0.041) when limited to the first evaluation.

Conclusion

RECIST 1.1 was useful even as early therapeutic evaluation for HCC patients treated with LEN. Understanding the characteristics of radiological response over time may contribute to improving the prognosis of patients with HCC.

Lenvatinib as first-line therapy for recurrent hepatocellular carcinoma after liver transplantation: Is the current evidence applicable to these patients?

Liver transplantation (LT) is one of the leading curative therapies for hepatocellular carcinoma (HCC). Despite recent optimization of transplant selection criteria, including alpha-feto protein, HCC recurrence after LT is still the leading cause of death in these patients. During the last decades, effective systemic treatments for HCC, including tyrosine kinase inhibitors and immunotherapy, have been approved. We describe the clinical scenario of a patient with recurrence of HCC five years after LT, who received lenvatinib as first-line systemic therapy to introduce systemic treatment options in this clinical setting. In this opinion review, we detail first and second-line systemic treatment options, focusing on those feasible for patients with recurrent HCC after LT. Several trials have evaluated new drugs to treat HCC patients in first and second-line therapy, but patients with recurrent HCC after LT have been excluded from these trials. Consequently, most of the evidence comes from observational retrospective studies. Whether tyrosine kinase inhibitors will remain the primary therapeutic approach in these patients, due to a relative contraindication for immunotherapy, may be clarified in the near future.

Effect of Handgrip Strength on Clinical Outcomes of Patients with Hepatocellular Carcinoma Treated with Lenvatinib

Previous studies have reported prognostic factors for hepatocellular carcinoma (HCC) patients receiving lenvatinib; however, no studies have evaluated the effects of both handgrip strength and skeletal muscle mass on the clinical outcomes. Therefore, this retrospective study investigated the individual effect of handgrip strength, skeletal muscle mass, and sarcopenia on clinical outcomes of 53 HCC patients treated with lenvatinib. Before receiving lenvatinib, handgrip strength and skeletal muscle index (SMI) were measured. Low handgrip strength and muscle depletion were defined as <26 and <18 kg and SMI <42 and SMI <38 cm2/m2 in men and women, respectively. Sarcopenia was defined as having low handgrip strength and muscle depletion. Multivariate analysis identified modified albumin–bilirubin grade 1–2a (p = 0.010), Barcelona Clinic Liver Cancer stage A–B (p = 0.011), and absence of low handgrip strength (p = 0.015) as favorable prognostic factors for survival. Furthermore, sarcopenia was an independent significant prognostic factor for survival. Time to treatment failure was associated with handgrip strength and sarcopenia. Our findings suggest that handgrip strength may be a useful marker of clinical outcomes in HCC patients treated with lenvatinib.

Clinical Significance of Adverse Events for Patients with Unresectable Hepatocellular Carcinoma Treated with Lenvatinib: A Multicenter Retrospective Study

We sought to investigate the clinical profile(s) associated with the discontinuation of lenvatinib (LEN) due to severe adverse events (DLSAE) in patients with unresectable hepatocellular carcinoma (HCC). This retrospective study enrolled 177 patients with HCC treated with LEN. Independent factors associated with DLSAE were advanced age, albumin-bilirubin (ALBI) grade 2, fatigue grade ≥ 3, and appetite loss ≥ 2. The overall survival (OS) in the group that did not require DLSAE was significantly longer compared to the group that did require DLSAE (median survival time (MST): not reached vs. 12.8 months, p < 0.001). Moreover, advanced age was the most important variable for DLSAE in a decision tree analysis. Hypertension and hand-foot-skin-reaction (HFSR) were also significantly associated with longer survival, and the occurrence of hypertension was the earliest predictor for improved prognosis, while appetite loss and development of grade ≥ 3 fatigue were predictive of a poor prognosis. We concluded that the appearance of hypertension has potential as an early surrogate marker to predict improved prognosis. Moreover, careful management to avoid discontinuation of treatment leads to longer survival in patients receiving LEN.

Lenvatinib prolongs the progression-free survival time of patients with intermediate-stage hepatocellular carcinoma refractory to transarterial chemoembolization: A multicenter cohort study using data mining analysis

Tyrosine kinase inhibitors are considered for use in patients with hepatocellular carcinoma (HCC) refractory to transarterial chemoembolization (TACE). The aim of the present retrospective study was to identify factors associated with progression-free survival (PFS) and to evaluate the indications for lenvatinib treatment in patients with intermediate-stage HCC refractory to TACE using a data-mining analysis. A total of 171 patients with intermediate-stage HCC refractory to TACE were included. All patients were classified into three groups according to their HCC treatment: Lenvatinib (n=45), sorafenib (n=53) and TACE (n=73) groups. PFS time was calculated using the Kaplan-Meier method and analyzed using a log-rank test. Factors associated with PFS time were evaluated using multivariate and decision-tree analyses. The median PFS time was 5.8, 3.2 and 2.4 months in the lenvatinib, sorafenib and TACE groups, respectively (P<0.001). In the Cox regression analysis, lenvatinib treatment and being within the up-to-seven criteria were identified as independent factors for PFS (lenvatinib, P<0.0001; within up-to-seven, P=0.001). The decision-tree analysis revealed that patients beyond the up-to-seven criteria, treated with lenvatinib and with albumin-bilirubin (ALBI) grade 1 had a longer PFS time (245.2±107.9 days) than patients beyond the up-to-seven criteria, treated with lenvatinib and with ALBI grade 2 (147.1±78.6 days). Additionally, lenvatinib was independently associated with longer PFS time in patients with intermediate-stage HCC refractory to TACE. Therefore, lenvatinib may be recommended for patients who have intermediate-stage HCC refractory to TACE, ALBI grade 1 and who are within the up-to-seven criteria.
