A combination of the preoperative neutrophil-to-lymphocyte and lymphocyte-to-monocyte ratios as a useful predictor of survival outcomes following the transarterial chemoembolization of huge hepatocellular carcinoma

Neutrophil–lymphocyte ratio is associated with worse outcomes in patients with cirrhosis: insights from the PRO-LIVER Registry

Background

Liver cirrhosis (LC) is a leading global cause of morbidity and mortality, with inflammation playing a key role in disease progression and clinical complications of LC. The Neutrophil/Lymphocyte Ratio (NLR), a readily available marker of systemic inflammation, has been linked to short-term adverse outcomes in LC, but data on long-term follow-up are limited. This study aimed to investigate the relationship between NLR and long-term all-cause mortality in an unselected cohort of LC patients.

Methods

Data were gathered from the Italian multicenter observational study “PRO-LIVER”. Patients with available data to calculate NLR at baseline were included. Baseline clinical determinants of NLR and the association of NRL with all-cause mortality at 2-year follow-up were evaluated.

Results

From the overall cohort (n = 753), 506 patients with LC (31% female, mean age 64.8 ± 11.9 years) were included in the analysis. Median value of NLR was 2.42 (Interquartile Range [IQR]: 1.61–3.52). At baseline, patients with NLR ≥ 2.42 were more likely to have Child–Pugh B or C, hepatocellular carcinoma (HCC), or portal vein thrombosis (PVT). After a median follow-up of 21 months, 129 patients died: 44 (17%) with NLR < 2.42 and 85 (34%) with NLR ≥ 2.42 (p < 0.001). At multiple-adjusted Cox regression analysis, NLR ≥ 2.42 was independently associated with all-cause mortality (HR: 1.65; 95% CI: 1.12–2.44; p = 0.012), along with age, Child–Pugh C class, HCC and PVT.

Conclusions

NLR is associated with long-term all-cause mortality in LC. NLR may serve as a potentially easily available tool to aid risk refinement in LC.

Evaluation of Inflammatory Markers as Prognostic Factors in the Treatment of Hepatocellular Carcinoma (HCC) with Degradable Starch Microspheres by Transarterial Chemoembolization (DSM-TACE)

Objective: To evaluate the prognostic value of pre-therapeutic inflammatory markers before transarterial chemoembolization with degradable starch microspheres (DSM-TACE) in the treatment of hepatocellular carcinoma (HCC). Methods: A total of 155 patients (81% male, median age: 68 years) who underwent first-time DSM-TACE between 07/13 and 06/22 were included in the study. Inflammatory indices were dichotomized using median values. Cox proportional hazard model for univariate (UVA) and multivariate (MVA) analyses (hazard ratio; 95% CI, p-value) and Kaplan-Meier analyses (overall survival (OS) in months; 95% CI; log-rank test) were performed. Results: The median OS of the study cohort was 15.9 (12.9-20) months with a median survival according to BCLC stages A (12%), B (41%), and C (47%) of median not reached, 19.3 (15.3-27), and 7.2 (4.5-9.0) months, respectively (p < 0.0001). In the UVA, several inflammatory markers on OS were statistically significant with the systemic inflammatory response index (SIRI; ≤median (2.04) HR: 0.41 (0.19-0.89); p = 0.024) and the lymphocyte to monocyte ratio (LMR; >median (1.82) HR: 0.44 (0.2-0.9); p = 0.025) remaining statistically significant in MVA together with the BCLC stage (p = 0.0001), ALBI grade (p = 0.016), hepatic tumor burden (≤25% vs. >25%; p = 0.006), and largest HCC lesion (≤5.5 cm vs. >5.5 cm; p = 0.008). In subgroup analysis, patients with elevated LMR and reduced SIRI exhibited significantly prolonged overall survival (OS) in both BCLC B (p < 0.0001) and Child-Pugh A (p = 0.021) subgroups. Conclusion: The findings suggest that SIRI and LMR may serve as valuable tools in identifying BCLC B and Child-Pugh A patients who could potentially benefit better from DSM-TACE treatment. Nevertheless, further research is recommended to confirm these findings and to provide more comprehensive insights.

Prognostic Role of Lymphocyte-to-Monocyte Ratio (LMR) in Patients with Intermediate-Stage Hepatocellular Carcinoma (HCC) Undergoing Chemoembolizations (DEM-TACE or cTACE) of the Liver: Exploring the Link between Tumor Microenvironment and Interventional Radiology

Inflammation-based scores are biomarkers of the crosstalk between the tumor microenvironment and the immune response. Investigating the intricate relationship between the tumor stromal microenvironment, biomarkers, and the response to transcatheter arterial chemoembolization (TACE) is essential for early identification of TACE refractoriness or failure, providing insights into tumor biology and facilitating personalized therapeutic interventions. This study addresses a dearth of recent literature exploring the prognostic significance of the preoperative LMR in individuals from western countries diagnosed with stage B hepatocellular carcinoma (HCC) undergoing drug eluting microspheres TACE (DEM-TACE) or conventional TACE (cTACE). This international multi-center retrospective analysis included consecutive patients with stage B HCC who underwent TACE from January 2017 to June 2023. The study evaluated the ability of the preoperative LMR to predict complete response (CR), objective response (OR), sustained response duration (SRD) exceeding 6 months, successful downstaging at 6 months, progression-free survival (PFS) at 6 months, and overall survival (OS) at 6 months. The study population included 109 HCC patients and it was divided into low LMR (LMR < 2.24) and high LMR (LMR ≥ 2.24) groups, according to ROC curve analysis to select the optimal LMR cut-off value. High LMR was associated with lower Hepatitis C prevalence, higher absolute lymphocyte count, and a trend toward lower alpha-fetoprotein. The group with high LMRs exhibited superior CR rates (14.9% vs. 0%), overall OR (43.2% vs. 14.3%), and better PFS at 6 months (75.7% vs. 45.7%). The LMR, specifically categorized as <2.24 and ≥2.24, emerged as a robust predictor for treatment response and short-term outcomes in patients with stage B HCC undergoing DEM- or c-TACE.

Which is the best TACE agent for patients with different NLR hepatocellular carcinomas? A systematic review and network meta-analysis

Background

Transarterial chemoembolization (TACE) is a common treatment for hepatocellular carcinoma (HCC), but the best therapeutic agent for TACE treatment has not been determined. The neutrophil/lymphocyte ratio (NLR) is a systemic immune system marker; however, the ability of the NLR to predict the prognosis of patients with HCC is unknown, and no studies have been conducted to determine the most appropriate TACE regimen for HCC patients with different NLRs.

Methods

The PubMed, Embase, Web of Science, and CNKI databases were searched through May 28, 2023. Comparisons of overall survival (OS) among cohort studies with different NLRs and different TACE treatment regimens were performed with a random effects model.

Findings

Thirty-five studies involving 9210 patients were included in this meta-analysis. The results showed that Group 3-4 (NLR<2.5) patients had a significantly longer OS than Group 1-2 (NLR 2.5-5.0). Among the patients, Group 1-3 (NLR 2.0-5.0) patients had the best survival after treatment with adriamycin (lnHR (95 % CI = 0.48 [0.31, 0.75] and lnHR (95 % CI = 0.41 [0.19, 0.91]). Among the Group 4 patients (NLR<2.0), the best outcome was obtained with platinum + adriamycin (lnHR (95 % CI = 0.59 [0.45, 0.78]), followed by adriamycin. A subgroup analysis of TACE combined with other treatments showed that adriamycin combined with sorafenib was the most effective and superior to the other treatment agents.

Interpretation

The NLR can be used to predict the prognosis of HCC patients treated with TACE; the higher the NLR is, the worse the prognosis. Adriamycin may be the best therapeutic agent for HCC patients treated with TACE.

A Multicenter International Retrospective Investigation Assessing the Prognostic Role of Inflammation-Based Scores (Neutrophil-to-Lymphocyte, Lymphocyte-to-Monocyte, and Platelet-to-Lymphocyte Ratios) in Patients with Intermediate-Stage Hepatocellular Carcinoma (HCC) Undergoing Chemoembolizations of the Liver

BACKGROUND

The utilization of inflammation-based scores, such as the Neutrophil-to-Lymphocyte Ratio (NLR), Lymphocyte-to-Monocyte Ratio (LMR), and Platelet-to-Lymphocyte Ratio (PLR), has garnered attention for their potential as prognostic indicators in various cancers. However, their predictive role in patients with intermediate-stage HCC undergoing transcatheter arterial chemoembolization (TACE) remains an area that requires further investigation, as early recognition of TACE refractoriness holds the potential to guide tailored therapeutic interventions.

METHODS

This multicenter international retrospective study analyzed data from patients with intermediate-stage HCC undergoing TACE between 2018 and 2024. Inflammation-based scores (NLR, LMR, PLR) were assessed preoperatively to predict treatment outcomes.

RESULTS

Two hundred and fourteen patients were enrolled. Preoperative LMR showed the largest area under the curve for the prediction of 6-months PFS, based on the ROC curve analysis. Both high LMR (≥2.24) and low NLR (<4.72) were associated with improved objective response rates and 6-month progression-free survival. Lymphocyte count emerged as a strong predictor of treatment response in both simple (p < 0.001) and multiple (p < 0.001) logistic regression analyses.

CONCLUSIONS

This study highlights the prognostic value of inflammation-based scores, particularly LMR and NLR, in predicting the treatment response and short-term outcomes of patients with intermediate-stage HCC undergoing TACE. Future investigations should focus on validating these scores' clinical applicability and assessing their impact on long-term patient survival and therapeutic decision-making.

Clinical factors associated with the therapeutic efficacy of atezolizumab plus bevacizumab in patients with unresectable hepatocellular carcinoma: A multicenter prospective observational study

The treatment efficiency and predictors of atezolizumab plus bevacizumab therapy for unresectable hepatocellular carcinoma in real-world practice have not been established. This study aimed to assess the efficacy and safety of atezolizumab plus bevacizumab and to investigate predictors of progression-free survival and overall survival. Patients with unresectable hepatocellular carcinoma treated with atezolizumab plus bevacizumab therapy in 19 hospitals were enrolled before treatment and observed prospectively. The outcomes of 222 patients in this cohort were analyzed. The objective response rate and disease control rate were 22.0% and 70.6%, respectively, whereas the median progression-free survival was 5.7 months. Independent risk factors for shortened progression-free survival were younger age (<75 years; 3.9 months vs. 8.6 months), higher number of intrahepatic tumors (≥5; 4.0 months vs. 7.9 months), macrovascular invasion (2.3 months vs. 6.7 months), and higher neutrophil-to-lymphocyte ratio (≥3.03; 3.0 months vs. 7.8 months). The median overall survival was not reached; however, independent risk factors for shortened overall survival were absence of hyperlipidemia, higher number of intrahepatic tumors (≥5), macrovascular invasion, higher α-fetoprotein level (≥400 ng/mL), worse Child-Pugh score (≥6), and higher neutrophil-to-lymphocyte ratio (≥3.03). Severe adverse events (grade ≥3) were observed in 96 patients (36.0%), with proteinuria being the most frequent. In conclusion, patients with older age, lower number of intrahepatic tumors, absent macrovascular invasion, and lower neutrophil-to-lymphocyte ratio are expected to have better progression-free survival with atezolizumab plus bevacizumab therapy for unresectable hepatocellular carcinoma.

Prognostic Role of Neutrophil-to-Lymphocyte Ratio (NLR), Lymphocyte-to-Monocyte Ratio (LMR), Platelet-to-Lymphocyte Ratio (PLR) and Lymphocyte-to-C Reactive Protein Ratio (LCR) in Patients with Hepatocellular Carcinoma (HCC) undergoing Chemoembolizations (TACE) of the Liver: The Unexplored Corner Linking Tumor Microenvironment, Biomarkers and Interventional Radiology

TACE plays a pivotal role in hepatocellular carcinoma, from disease control to downstaging and bridging to liver transplant. Response to TACE is a surrogate marker of tumor aggressive biology, with manifold practical implications such as survival, the need for more aggressive treatments in the intermediate stage, the selection of patients on the transplant waiting list, the dropout rate from the transplant list and the post-transplant recurrence rate. Inflammation-based scores are biomarkers of the relationship between the tumor stromal microenvironment and the immune response. Investigating the connection among the tumor stromal microenvironment, biomarkers, and the response to TACE is crucial to recognize TACE refractoriness/failure, thus providing patients with tailored therapeutics. This review aims to provide a comprehensive overview of the prognostic roles of the neutrophil-to-lymphocyte ratio (NLR), the lymphocyte-to-monocyte ratio (LMR), the platelet-to-lymphocyte ratio (PLR), and the lymphocyte-to-C reactive protein ratio (LCR) in patients with HCC undergoing chemoembolization of the liver. Inflammation-based scores may be convenient, easily obtained, low-cost, and reliable biomarkers with prognostic significance for HCC undergoing TACE. Baseline cut-off values differ between various studies, thus increasing confusion about using of inflammation-based scores in clinical practice. Further investigations should be conducted to establish the optimal cut-off values for inflammation-based scores, consolidating their use in clinical practice.
