The Severity of Liver Fibrosis Influences the Prognostic Value of Inflammation-Based Scores in Hepatitis B-Associated Hepatocellular Carcinoma

Albumin–Globulin Score Combined with Skeletal Muscle Index as a Novel Prognostic Marker for Hepatocellular Carcinoma Patients Undergoing Liver Transplantation

Background: Sarcopenia was recently identified as a poor prognostic factor in patients with malignant tumors. The present study investigated the effect of the preoperative albumin–globulin score (AGS), skeletal muscle index (SMI), and combination of AGS and SMI (CAS) on short- and long-term survival outcomes following deceased donor liver transplantation (DDLT) for hepatocellular carcinoma (HCC) and aimed to identify prognostic factors. Methods: A total of 221 consecutive patients who underwent DDLT for HCC were enrolled in this retrospective study between January 2015 and December 2019. The skeletal muscle cross-sectional area was measured by CT (computed tomography). Clinical cutoffs of albumin (ALB), globulin (GLB), and sarcopenia were defined by receiver operating curve (ROC). The effects of the AGS, SMI, and CAS grade on the preoperative characteristics and long-term outcomes of the included patients were analyzed. Results: Patients who had low AGS and high SMI were associated with better overall survival (OS) and recurrence-free survival (RFS), shorter intensive care unit (ICU) stay, and fewer postoperative complications (grade ≥ 3, Clavien–Dindo classification). Stratified by CAS grade, 46 (20.8%) patients in grade 1 were associated with the best postoperative prognosis, whereas 79 (35.7%) patients in grade 3 were linked to the worst OS and RFS. The CAS grade showed promising accuracy in predicting the OS and RFS of HCC patients [areas under the curve (AUCs) were 0.710 and 0.700, respectively]. Male recipient, Child–Pugh C, model for end-stage liver disease (MELD) score > 20, and elevated CAS grade were identified as independent risk factors for OS and RFS of HCC patients after DDLT. Conclusion: CAS grade, a novel prognostic index combining preoperative AGS and SMI, was closely related to postoperative short-term and long-term outcomes for HCC patients who underwent DDLT. Graft allocation and clinical decision making may be referred to CAS grade evaluation.

Insights into the Association Between QSER1 and M2 Macrophages and Remarkable Malignancy Characteristics in Hepatocellular Carcinoma

Purpose

Glutamine and serine rich 1 (QSER1), as a DNA methylation modulator, play a crucial role in transforming tumor cells. Previous studies have shown that QSER1 plays a role in regulating the progression of various malignancies and that QSER1 dysfunction is connected with precancerous lesions of hepatocellular carcinoma (HCC) as well as HCC prognosis. However, little is known about the detailed contribution of QSER1 in HCC.

Patients and Methods

Various statistical methods such as Kaplan–Meier method, AUC analysis, GSEA, and immune-infiltration analysis were used to evaluate the relationship between QSER1 expression and clinical features, prognostic factors, and potential functional mechanisms of QSER1.

Results

QSER1 expression was negatively correlated with clinicopathological features (clinical stage, pathological grade, TP53 mutation, lymph node metastasis) and clinical outcome (overall survival versus recurrence). Functional enrichment analysis further suggested that QSER1 is involved in multiple pathways related to DNA replication and tumor immunity. TIMER analysis indicated that high QSER1 expression was significantly associated with higher macrophage infiltration and poorer macrophage-related outcomes. In particular, QSER1 was significantly more associated with M2 macrophages than M1 macrophages.

Conclusion

Overall, elevated QSER1 is a potential prognostic marker for HCC and is associated with immune infiltration in HCC.

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.

Prognostic value of liver stiffness measurement in patients with hepatocellular carcinoma (HCC) treated by radiofrequency ablation: a meta-analysis

BACKGROUND

In patients with stage 0-A (as per Milan criteria) hepatocellular carcinoma (HCC) image-guided ablation is less invasive and requires shorter hospitalization than resection, but long-term prognosis is poorer. This meta-analysis was conducted to investigate whether liver stiffness measurement (LSM) could be used to predict prognosis in HCC patients after tumor ablation.

METHODS

A literature search was conducted for all studies published till July 2020 in PubMed, Web of Science, Cochrane Library and EMBASE. Studies were included if they investigated the association between pretreatment LSM and prognosis in HCC patients treated with ablation. Subgroup analysis, meta-regression, publication bias assessment and sensitivity were conducted.

RESULTS

Eight studies (with a total of 1276 HCC patients) were included in this meta-analysis. All patients were treated with radiofrequency ablation. Pooled results showed that high pretreatment LSM were associated with poor overall survival (OS) (hazard ratio [HR] = 4.31, 95% confidence interval [CI]: 2.27-8.20, p < .001) and recurrence-free survival (RFS), regardless of whether LSM was considered as a categorical variable (HR = 2.63, 95% CI = 1.63-4.22, p < .001) or as a continuous variable (HR = 1.02, 95% CI = 1.01-1.04, p = .003). Among studies treating LSM value as a categorical variable, liver stiffness measured using acoustic radio force impulse (ARFI) or transient elastography (TE) was significantly associated with RFS, but not liver stiffness measured using two-dimensional shear wave elastography (SWE).

CONCLUSIONS

High baseline LSM value appears to be associated with poor prognosis in HCC patients treated with radiofrequency ablation.

Thrombocytopenia in Virus Infections

Thrombocytopenia, which signifies a low platelet count usually below 150 × 10⁹/L, is a common finding following or during many viral infections. In clinical medicine, mild thrombocytopenia, combined with lymphopenia in a patient with signs and symptoms of an infectious disease, raises the suspicion of a viral infection. This phenomenon is classically attributed to platelet consumption due to inflammation-induced coagulation, sequestration from the circulation by phagocytosis and hypersplenism, and impaired platelet production due to defective megakaryopoiesis or cytokine-induced myelosuppression. All these mechanisms, while plausible and supported by substantial evidence, regard platelets as passive bystanders during viral infection. However, platelets are increasingly recognized as active players in the (antiviral) immune response and have been shown to interact with cells of the innate and adaptive immune system as well as directly with viruses. These findings can be of interest both for understanding the pathogenesis of viral infectious diseases and predicting outcome. In this review, we will summarize and discuss the literature currently available on various mechanisms within the relationship between thrombocytopenia and virus infections.

Development of a Novel Inflammation-Based Index for Hepatocellular Carcinoma

BACKGROUND

The aim of current study was to (1) construct and validate a novel hepatocellular carcinoma (HCC)-specific inflammatory index; (2) compare the performances of the Integrated Liver Inflammatory Score (ILIS) to existing 4 inflammatory indices in HCC; (3) explore the association between the inflammatory indices and systemic/intratumoral inflammatory markers.

METHODS

Two cohorts from Hong Kong (HK; n = 1,315) and Newcastle (n = 574) were studied. A novel index was constructed from the HK training set (n = 627). The index was constructed from the training set by combing independent prognostic circulating parameters, followed by validating in the validation set of HK cohort (n = 688) and the Newcastle cohort. Its prognostic performance was compared to 4 inflammatory indices, namely, the neutrophil to lymphocyte ratio, platelet-to-lymphocyte ratio, prognostic nutrition index, and systemic immune-inflammation index, were compared in the HK cohort. Circulating cytokines and intratumoral gene expression were analyzed in a subset of patients with available samples and correlated with the inflammatory indices.

RESULTS

In the training set of the HK cohort, the ILIS, was generated: -0.057 × albumin (g/L) + 0.978 × log (Bilirubin, µmol/L) + 1.341 × log (alkaline phosphatase, IU/L) + 0.086 × Neutrophil (10⁹/L) + 0.301 × log (alpha-fetoprotein, µg/L). With cutoff of 2.60 and 3.87, the ILIS could categorize patients into 3 risk groups in the both validation cohorts. ILIS outperforms other inflammatory indices and remains an independent prognosticator for overall survival after adjustment with Barcelona Clinic Liver Cancer (hazard ratio 31.90, p < 0.001). The ILIS had the best prognostic performances as compared to other inflammatory indices. In exploratory analyses, the ILIS correlated with circulating inflammatory cytokines (e.g., IL-8) but not with any intratumoral inflammatory gene expression.

CONCLUSIONS

ILIS is an HCC-specific prognostic index built on 5 readily available blood parameters. Its versatility is validated both Eastern and Western population of HCC. The score is correlated with levels of circulating cytokines.

Cholecystectomy is associated with higher risk of recurrence after microwave ablation of hepatocellular carcinoma: a propensity score matching analysis

Objective: To explore the association between cholecystectomy and the prognostic outcomes of patients with hepatocellular carcinoma (HCC) who underwent microwave ablation (MWA).

Methods: Patients with HCC (n = 921) who underwent MWA were included and divided into cholecystectomy (n = 114) and non-cholecystectomy groups (n = 807). After propensity score matching (PSM) at a 1:2 ratio, overall survival (OS) and disease-free survival (DFS) rates were analyzed to compare prognostic outcomes between the cholecystectomy (n = 114) and non-cholecystectomy groups (n = 228). Univariate and multivariate Cox analyses were performed to assess potential risk factors for OS and DFS. Major complications were also compared between the groups.

Results: After matching, no significant differences between groups were observed in baseline characteristics. The 1-, 3-, and 5-year OS rates were 96.5%, 82.1%, and 67.1% in the cholecystectomy group, and 97.4%, 85.2%, and 74.4% in the non-cholecystectomy group (P = 0.396); the 1-, 3-, and 5-year DFS rates were 58.4%, 34.5%, and 26.6% in the cholecystectomy group, and 73.6%, 44.7%, and 32.2% in the non-cholecystectomy group (P = 0.026), respectively. The intrahepatic distant recurrence rate in the cholecystectomy group was significantly higher than that in the non-cholecystectomy group (P = 0.026), and the local tumor recurrence and extrahepatic recurrence rates did not significantly differ between the groups (P = 0.609 and P = 0.879). Multivariate analysis revealed that cholecystectomy (HR = 1.364, 95% CI 1.023–1.819, P = 0.035), number of tumors (2 vs. 1: HR = 2.744, 95% CI 1.925–3.912, P < 0.001; 3 vs. 1: HR = 3.411, 95% CI 2.021–5.759, P < 0.001), and γ-GT levels (HR = 1.003, 95% CI 1.000–1.006, P < 0.024) were independent risk factors for DFS. The best γ-GT level cut-off value for predicting median DFS was 39.6 U/L (area under the curve = 0.600, P < 0.05). A positive correlation was observed between cholecystectomy and γ-GT level (r = 0.108, 95% CI −0.001–0.214, P = 0.047). Subgroup analysis showed that the DFS rates were significantly higher in the non-cholecystectomy group than the cholecystectomy group when γ-GT ≥39.6 U/L (P = 0.044). The 5-, 10-, 15-, 20-, and 25-year recurrence rates from the time of cholecystectomy were 2.63%, 21.93%, 42.11%, 58.77%, and 65.79%, respectively. A significant positive correlation was observed between cholecystectomy and the time from cholecystectomy to recurrence (r = 0.205, 95% CI 0.016–0.379, P = 0.029). There were no significant differences in complications between groups (P = 0.685).

Conclusions: Patients with HCC who underwent cholecystectomy were more likely to develop intrahepatic distant recurrence after MWA, an outcome probably associated with increased γ-GT levels. Moreover, the recurrence rates increased with time.

The Preoperative Prognostic Nutritional Index in Hepatocellular Carcinoma After Curative Hepatectomy: A Retrospective Cohort Study and Meta-Analysis

OBJECTIVE

Conflicting results existed about the role of prognostic nutritional index (PNI) for hepatocellular carcinoma (HCC) patients who received curative hepatectomy. The aim of this study is to identify the predictive capacity of PNI for survival after hepatectomy.

METHODS

Preoperative PNI, neutrophil-to-lymphocyte ratio (NLR), tumor feature and clinical information of 187 patients with HCC from Sir Run Run Shaw hospital were evaluated. We also conducted a meta-analysis of seven cohort studies.

RESULTS

Our study showed that HCC patients with a low PNI of <45 had a poor recurrence-free survival (RFS) rate (hazard ratio [HR] 1.762, 95% confidence interval [CI] 1.066-2.911, p = 0.027, respectively). The 5-year OS and RFS rates of the high PNI (≥45) vs low PNI (<45) were 76.7% vs 50.1% (p = 0.001) and 47.0% vs 28.9% (p = 0.001), respectively. In HCC TNM I patients (n = 144), a low PNI remained an independent prognostic factor of OS and RFS (HR 2.305, 95% CI 1.008-5.268, p = 0.048; HR 2.122, 95% CI 1.149-3.920, p = 0.016). The 5-year OS and RFS rates of the high PNI vs low PNI were 81.3% vs 62.4% (p = 0.041) and 53.4% vs 45.6% (p = 0.013), respectively. In the pooled analysis, the data showed that a low PNI was significantly associated with poor OS and RFS (HR 2.27, 95% CI 1.03-4.07, p < 0.001 and HR 1.68, 95% CI 1.45-1.94, p < 0.001, respectively).

CONCLUSIONS

The preoperative PNI was an independent prognostic factor for OS and RFS rates in HCC patients who received hepatectomy.

Combined preoperative albumin-bilirubin (ALBI) and serum γ-glutamyl transpeptidase (GGT) predicts the outcome of hepatocellular carcinoma patients following hepatic resection

Background: Liver function is an important prognostic factor for patients with hepatocellular carcinoma. The purpose of this study was to develop and validate a nomogram integrating the albumin-bilirubin (ALBI) and serum γ-glutamyl transpeptidase (GGT) level to predict postoperative overall survival (OS) and disease-free survival (DFS) of hepatocellular carcinoma (HCC).

Methods: The effect of combined of ALBI and GGT on HCC prognosis was investigated using univariate and multivariate Cox analyses. The nomogram for OS and DFS were developed, respectively, and their predictive ability was compared with other conventional staging systems, including the American Joint Commission on Cancer (AJCC), Barcelona Clinic Liver Cancer (BCLC) and the Cancer of the Liver Italian Program (CLIP).

Results: Combined ALBI and GGT was highly associated with OS (P<0.001) and DFS (P<0.001) of HCC patients treated with hepatic resection. In addition, the C-index of the OS (0.706±0.034) or DFS (0.674±0.032) nomogram in the training cohort was larger than AJCC, BCLC and CLIP. The Akaike information criterion (AICs) of the OS (2178.405) or DFS (2961.018) nomogram in the training cohort was smaller than above staging systems. The results suggested that the OS or DFS nomogram was the most powerful model to predict HCC prognosis. The similar trend was observed in the validation cohort.

Conclusion: The novel nomogram integrating ALBI and GGT was highly associated with OS and DFS of postoperative HCC patients.

Underlying liver disease and advanced stage liver cancer are associated with elevated neutrophil-lymphocyte ratio

Background/Aims

Inflammation-based scores, such as the neutrophil-to-lymphocyte ratio (NLR), have been associated with prognosis in hepatocellular carcinoma (HCC); but variable cut-off values and potential lack of specificity have limited the utility of NLR. This study evaluates NLR in a large cohort of HCC patients.

Methods

We retrospectively reviewed 789 HCC cases (1993–2017) for demographics, tumor characteristics, treatment, and survival. NLR was stratified into NLR ≥1.5 and NLR ≥3 and analyzed for correlation with American Joint Committee on Cancer (AJCC) and Barcelona Clinic Liver Cancer (BCLC) stages. In 235 patients who underwent liver resection, survival and recurrence were evaluated by NLR.

Results

In 789 HCC cases, mean NLR was increased with advanced AJCC and BCLC stages. Hepatitis C patients were less likely to have NLR ≥1.5 and ≥3. Non-alcoholic steatohepatitis patients were more likely to have NLR ≥3. Patients with tumor size >5 cm, rupture, or macrovascular invasion were more likely to have NLR ≥3. In patients treated with resection, NLR ≥3 predicted early recurrence (odds ratio [OR] 4.14, P<0.01) and overall recurrence (OR 4.05, P<0.01). Mean NLR was 4.30 in those with recurrence and 2.75 in those without recurrence. Patients with NLR ≥3 showed significantly worse survival compared to those with NLR <3 (P<0.01 by log-rank test).

Conclusions

Elevated NLR is associated with advanced cancer stage and aggressive tumor characteristics, such as large size, rupture, and invasion. NLR ≥3 was associated with early and overall recurrence after resection but varied with etiology. NLR may be a useful biomarker in predicting recurrence for HCC patients undergoing curative resection, but further studies are required to elucidate the effect of disease etiology.

Prognostic markers affecting the early recurrence of hepatocellular carcinoma with liver cirrhosis after curative resection

Background:

Early recurrence is associated with poor prognosis after curative resection for hepatocellular carcinoma. Thus, we studied which factors, including this inflammation-based scoring system, affect disease recurrence in single hepatocellular carcinoma patients with liver cirrhosis.

Methods:

A total of 430 consecutive hepatocellular carcinoma patients were enrolled in our institution between January 2002 and December 2015. Survival rate, univariate, and multivariate analyses were performed to identify the variables associated with recurrence and early recurrence especially.

Results:

The overall survival rate was significantly lower in the early recurrence group than in the non-early recurrence group ( P<0.001). According to the multivariate analysis, protein induced by vitamin K absence or antagonist (PIVKA) greater than 200 ( P=0.035), neutrophil-to-lymphocyte ratio greater than 2.0 ( P<0.001), elevated Glasgow prognostic score ( P=0.003), tumor size greater than 5 cm ( P=0.002), and the presence of lymphovascular invasion ( P=0.002) were significantly different among the groups and affected the early recurrence of hepatocellular carcinoma. The patients were categorized into five levels of risk for early recurrence according to the number of independent risk factors, and patients with no risk factors were set as the reference group.

Conclusion:

Neutrophil-to-lymphocyte ratio, Glasgow prognostic score, and serum level of PIVKA offer significant prognostic information associated with early recurrence following single lesion hepatocellular carcinoma patients with liver cirrhosis after curative resection.

Platelet-to-Lymphocyte Ratio and Large Tumor Size Predict Microvascular Invasion after Resection for Hepatocellular Carcinoma

Background:

Recurrence after curative resection of hepatocellular carcinoma (HCC) is associated with early death and poor prognosis. Microvascular invasion (mVI) is strongly associated with disease recurrence. Although many studies have examined the relationship between various serum inflammatory indices and post-treatment prognosis, little is known about preoperative predictors of microvascular invasion in HCC.

Methods:

Patients who underwent curative hepatic resection for HCC at our institute from January 2006 to December 2016 were retrospectively reviewed. The associations between mVI and various potential risk factors, including tumor size, hepatitis B and C virus infection, Child–Pugh scores, platelet-to-lymphocyte ratio, and neutrophil-to-lymphocyte ratio, were analyzed. Optimal cut-off values were determined using receiver operating characteristic curves.

Results:

A total of 330 HCC patients were enrolled in this study, of whom 74 (22.4%) had tumors with mVI. After univariate analysis, two parameters were significantly associated with mVI after hepatic resection: platelet-to-lymphocyte ratio ≥102 (odds ratio [OR] 2.385, p = 0.001) and tumor size ≥5 cm (OR 4.29, p < 0.001). Both variables remained significant risk factors for mVI after multivariate analysis: platelet-to-lymphocyte ratio ≥102 (OR 1.831, p = 0.034) and tumor size ≥5 cm (OR 3.791, p < 0.001).

Conclusions:

Large tumor size (≥5 cm) and high platelet-to-lymphocyte ratio (≥102) are independent predictive factors for mVI in HCC.

Prognostic significance of preoperative prognostic nutritional index in hepatocellular carcinoma: a meta-analysis

BACKGROUND

To date, epidemiological evidence of the association between preoperative prognostic nutritional index (PNI) and the prognosis of hepatocellular carcinoma (HCC) remains controversial.

METHODS

A literature search was performed in the databases of PubMed, Embase, and Web of Science. Hazard ratio (HR), odds ratio (OR), and 95% confidence interval (CI) were extracted to estimate the association of preoperative PNI with overall survival (OS), disease-free survival (DFS), and postoperative recurrence of HCC, respectively. A random-effects model was used to calculate the pooled effect size.

RESULTS

Thirteen studies with a total of 3,738 patients with HCC met inclusion criteria for this meta-analysis. It indicated that a lower level of preoperative PNI was a significant predictor of worse OS (HR = 1.82, 95%CI: 1.44-2.31) and DFS (HR = 1.49, 95% CI: 1.06-2.07). In addition, risk of postoperative recurrence was significantly higher in patients with a lower preoperative PNI (OR = 1.92, 95% CI: 1.33-2.76). Subgroup analysis based on therapeutic intent demonstrated a significant positive association between preoperative low PNI and worse OS for those patients undergoing surgical resection and for those undergoing TACE or non-surgical treatment.

CONCLUSION

The current meta-analysis demonstrates that preoperative PNI is a prognostic marker in HCC.

Risk of reduced platelet counts in patients with nonalcoholic fatty liver disease (NAFLD): a prospective cohort study

Background

The production of peripheral platelet is mainly regulated by thrombopoietin, which is a glycoprotein hormone predominantly synthesized in the liver. Previously, many studies have reported that there was an inverse correlation between the degree of chronic viral hepatitis and the peripheral platelet count. However, the effect of nonalcoholic fatty liver disease (NAFLD) on the peripheral platelet counts remains unclear.

Methods

With 1303 participants from “The prevention of MS and multi-metabolic disorders in Jiangsu province of China (PMMJS)” cohort study, we investigated the associations between NAFLD and the risk of platelet counts reduction in Chinese adults. The paired-samples T test was used to explore the platelet counts changes between baseline and follow-up. Multivariate logistic regression was used to examine the association between presence of NAFLD and the risk of platelet reduction by calculating the odds ratios (ORs) and 95% confidence interval (CI).

Results

After five years of follow-up, platelet counts were markedly reduced from 220.6 ± 42.22 (10⁹/L) at baseline to 208.41 ± 40.70 (10⁹/L) at follow-up in NAFLD group (P < 0.0001). However, platelet counts were slightly lowered from 213.2 ± 43.26(10⁹/L) at baseline to 211.8 ± 41.65 (10⁹/L) at follow-up in non-NAFLD people (P = 0.2349). Meanwhile, there was a significant association between NAFLD and the risks of platelet count reduction, even after adjustment for confounding variables (OR: 1.68, 95% CI: 1.06–2.67). Additionally, among the participants with BMI ≤ 23 kg/m² and SUA ≤ 344.3 μmol/L, the NAFLD participants have an increased risk of platelet count reduction compared to the persons in non-NAFLD group.

Conclusions

Our present results suggested that NAFLD individuals have an increased risk of platelet counts reduction.

Prognostic factors in patients with HBV-related hepatocellular carcinoma following hepatic resection

Background

To analyze prognostic factors following hepatic resection in patients with HBV-related hepatocellular carcinoma.

Methods

We retrospectively analyzed 217 patients with HBV-related hepatocellular carcinoma who underwent hepatic resection at our hospital between January 2006 and December 2015. Disease-free survival and overall survival rates were analyzed using the Kaplan–Meier method and the log-rank test. The association between recurrence and survival and various clinicopathological factors, including serum alpha-fetoprotein (AFP) level, platelet count, platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte ratio, antiplatelet therapy, antiviral therapy, hepatitis C virus infection, and tumor-related characteristics, were assessed using univariate and multivariate logistic regression analysis.

Results

The 1-, 3-, and 5-year overall survival rates were 91, 84, and 79%, respectively, and the recurrence-free survival rates were 72, 51, and 44%, respectively. High post-operative AFP level (hazard ratio [HR] 1.112, 95% confidence interval [CI]: 1.02–1.21, P = 0.007), multiple tumors (HR 1.991, 95% CI: 1.11–3.56, P = 0.021), and no antiviral treatment (HR 1.823, 95% CI: 1.07–3.09, P = 0.026) were independent risk factors for recurrence. High post-operative AFP level (HR 1.222, 95% CI: 1.09–1.36, P < 0.001), multiple tumors (HR 2.715, 95% CI: 1.05–7.02, P = 0.039), and recurrence (HR 12.824, 95% CI: 1.68–97.86, P = 0.014) were independent risk factors for mortality. No other factors analyzed were associated with outcomes in this patient cohort.

Conclusions

High post-operative serum alpha-fetoprotein level and multiple tumors, but not inflammatory factors, were risk factors for poor prognosis in HBV-related hepatocellular carcinoma patients after resection.

Preoperative neutrophil-to-lymphocyte ratio as a prognostic predictor after curative-intent surgery for hepatocellular carcinoma: experience from a developing country

Purpose

The aim of the study was to evaluate a prognostic value of preoperative neutrophil-to-lymphocyte ratio (NLR) on long-term survival of cirrhotic and noncirrhotic hepatocellular cancer (HCC) patients managed by a curative-intent liver surgery in a developing country.

Patients and methods

During the study period between November 1, 2001, and December 31, 2012, 109 patients underwent potentially curative hepatectomy for HCC. Data were retrospectively reviewed from the prospectively collected database. The median follow-up was 25 months. NLR was estimated by dividing an absolute neutrophil count by an absolute lymphocyte count from the differential blood count. Receiver operating characteristic curve was constructed to assess the ability of NLR to predict long-term outcomes and to determine an optimal cutoff value for all patients group, the subgroup with cirrhosis, and the subgroup without cirrhosis. The optimal cutoff values were 1.28, 1.28, and 2.09, respectively.

Results

The overall 3- and 5-year survival rates were 49% and 45%, respectively, for low NLR group and 38% and 26%, respectively, for high NLR group. The difference was statistically significant (p=0.015). Overall survival was similar between low and high NLR groups in patients with cirrhosis; no difference was found between the groups (p=0.124). In patients without cirrhosis, low NLR group had longer overall survival compared with high NLR group (p=0.015). Univariate analysis identified four factors as significant predictors of long-term survival: cirrhosis, Child-Pugh score, platelet count, and NLR. On multivariate analysis, only platelet count and NLR were independent prognostic factors of long-term survival.

Conclusion

Prognostic value of NLR was confirmed in noncirrhotic HCC patients who underwent curative-intent liver surgery. In HCC patients with cirrhosis, the prognostic role of NLR was not confirmed.

Neutrophil-to-lymphocyte ratio as prognostic indicator in gastrointestinal cancers: a systematic review and meta-analysis

An accurate, time efficient, and inexpensive prognostic indicator is needed to reduce cost and assist with clinical decision making for cancer management. The neutrophil-to-lymphocyte ratio (NLR), which is derived from common serum testing, has been explored in a variety of cancers. We sought to determine its prognostic value in gastrointestinal cancers and performed a meta-analysis of published studies using the Meta-analysis Of Observational Studies in Epidemiology guidelines. Included were randomized control trials and observational studies that analyzed humans with gastrointestinal cancers that included NLR and hazard ratios (HR) with overall survival (OS), disease-free survival (DFS), progression-free survival (PFS), and/or cancer-specific survival (CSS).

We analyzed 144 studies comprising 45,905 patients, two-thirds of which were published after 2014. The mean, median, and mode cutoffs for NLR reporting OS from multivariate models were 3.4, 3.0, 5.0 (±IQR 2.5-5.0), respectively. Overall, NLR greater than the cutoff was associated with a HR for OS of 1.63 (95% CI, 1.53-1.73; P < 0.001). This association was observed in all subgroups based on tumor site, stage, and geographic region. HR for elevated NLR for DFS, PFS, and CSS were 1.70 (95% CI, 1.52-1.91, P < 0.001), 1.64 (95% CI, 1.36-1.97, P < 0.001), and 1.83 (95% CI, 1.50-2.23, P < 0.001), respectively.

Available evidence suggests that NLR greater than the cutoff reduces OS, independent of geographic location, gastrointestinal cancer type, or stage of cancer. Furthermore, DFS, PFS, and CSS also have worse outcomes with elevated NLR.

Programmed death ligand 1 expression in esophageal cancer following definitive chemoradiotherapy: Prognostic significance and association with inflammatory biomarkers

Immunotherapy with anti-programmed cell death protein 1 or programmed death ligand 1 (PD-L1) agents has demonstrated promising efficacy for the treatment of various types of malignancies. However, the role of PD-L1 as a tumor prognostic marker remains poorly understood. In the present study, the prognostic value of PD-L1 expression in esophageal carcinoma (EC) following definitive chemoradiotherapy (CRT) was investigated, and its associations with three systemic inflammation biomarkers, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR) were further explored. A total of 104 patients with non-metastatic EC, who underwent definitive CRT between January 2009 and December 2012, were retrospectively analyzed. The expression of PD-L1 was examined by immunohistochemistry and the impact of PD-L1 expression level on overall survival (OS) was assessed. Furthermore, pretreatment neutrophil, lymphocyte, platelet and monocyte counts were obtained from routine blood tests to calculate the NLR, PLR and LMR. PD-L1 was overexpressed in EC compared with normal esophageal epithelium, with a positive expression rate of 37.5%. Additionally, patients with positive PD-L1 expression had a lower NLR than those with negative PD-L1 expression (P=0.001). On multivariate analysis, the positive staining of PD-L1 was significantly associated with improved OS (HR, 0.6; 95% CI, 0.372–0.965; P=0.035). Kaplan-Meier survival analysis showed a similar result (P=0.009). Additionally, sex (HR, 0.449; 95% CI, 0.229–0.880; P=0.020), clinical stage III (HR, 2.471; 95% CI, 1.171–5.212; P=0.018), and receipt of concurrent chemoradiation (HR, 0.590; 95% CI, 0.368–0.945; P=0.028) were all independent prognostic factors in EC treated with definitive CRT. The correlation of NLR with PD-L1 expression validated the relevance of immunity and inflammation. In summary, the present study demonstrated that positive PD-L1 expression is associated with improved survival in patients with EC treated with radical CRT, indicating that PD-L1 is a promising prognostic marker.

Pretreatment neutrophil-lymphocyte ratio: useful prognostic biomarker in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is the most common liver malignancy and the third most common cause of cancer-related deaths. Liver resection (LR) and liver transplantation (LT) are the only curative modalities for HCC. Despite recent advances and the adoption of the Milan and University of California, San Francisco, criteria, HCC recurrence after LR and LT remains a challenge. Several markers and prognostic scores have been proposed to predict tumor aggressiveness and supplement radiological data; among them, neutrophil–lymphocyte ratio (NLR) has recently gained significant interest. An elevated NLR is thought to predispose to HCC recurrence by creating a protumorigenic microenvironment through both relative neutrophilia and lymphocytopenia. In the present review, we attempted to summarize the published work on the role of pretreatment NLR as a prognostic marker for HCC following LR and LT. A total of 13 LT and 18 LR studies were included from 2008 to 2015. Pretransplant NLR was most often predictive of HCC recurrence, recurrence-free survival, and overall survival. NLR was, however, more variably and less clearly associated with worse outcomes following LR.

The role of the systemic inflammatory response in predicting outcomes in patients with operable cancer: Systematic review and meta-analysis

Cancer remains a leading causes of death worldwide and an elevated systemic inflammatory response (SIR) is associated with reduced survival in patients with operable cancer. This review aims to examine the evidence for the role of systemic inflammation based prognostic scores in patients with operable cancers. A wide-ranging literature review using targeted medical subject headings for human studies in English was carried out in the MEDLINE, EMBASE, and CDSR databases until the end of 2016. The SIR has independent prognostic value, across tumour types and geographical locations. In particular neutrophil lymphocyte ratio (NLR) (n = 158), platelet lymphocyte ratio (PLR) (n = 68), lymphocyte monocyte ratio (LMR) (n = 21) and Glasgow Prognostic Score/ modified Glasgow Prognostic Score (GPS/mGPS) (n = 60) were consistently validated. On meta-analysis there was a significant relationship between elevated NLR and overall survival (OS) (p < 0.00001)/ cancer specific survival (CSS) (p < 0.00001), between elevated LMR and OS (p < 0.00001)/CSS (p < 0.00001), and elevated PLR and OS (p < 0.00001)/CSS (p = 0.005). There was also a significant relationship between elevated GPS/mGPS and OS (p < 0.00001)/CSS (p < 0.00001). These results consolidate the prognostic value of the NLR, PLR, LMR and GPS/mGPS in patients with resectable cancers. This is particularly true for the NLR/GPS/mGPS which should form part of the routine preoperative and postoperative workup.

Clinical significance of preoperative liver stiffness measurements in primary HBV-positive hepatocellular carcinoma

AIM

To analyze clinical significance of preoperative liver stiffness measurement (LSM) by FibroScan in postcurative resection hepatitis B virus (HBV) related hepatocellular carcinoma (HCC).

PATIENTS & METHODS

A total of 263 patients underwent preoperative LSM and curative operation for primary HBV-positive HCC were enrolled. The correlation between preoperative LSM and survival was analyzed.

RESULTS

All patients were stratified into two groups using the optimal cut-off value (13.2 kPa) of LSM using the receiver-operating characteristic. Patients with an LSM ≥13.2 kPa had poorer overall survival (median, 61.3 vs 48.2 months, hazard ratio: 0.15; p = 0.009) and recurrence-free survival (median, 60.4 vs 47.0 months; hazard ratio: 0.32; p = 0.011) than patients with an LSM <13.2 kPa and LSM also have been confirmed as independent predictor for survival for HCC.

DISCUSSION

This could potentially guide patient stratification and individualized treatment.

CONCLUSION

Preoperative LSM can be considered as an independent prognostic factor for HBV-positive HCC after curative resection.

Preoperative Albumin-Bilirubin Score for Postoperative Solitary Hepatocellular Carcinoma within the Milan Criteria and Child-Pugh A Cirrhosis

Surgical resection remains the initial treatment of choice for the majority of early stage hepatocellular carcinoma (HCC) patients. Although the factors that influence the prognosis of postoperative HCC patients have been well elucidated, there are a limited number of simple, objective, and distinct methods for estimating survival for postoperative patients with solitary HCC within the Milan criteria and Child-Pugh (C-P) A cirrhosis. The Albumin-Bilirubin (ALBI) score is a new evidence-based approach to assess liver function. The ALBI score eliminates subjective variables, such as ascites and encephalopathy which are the requirements for the conventional C-P grading system. This study enrolled 654 patients to determine whether the ALBI score can predict the outcomes of postoperative solitary HCC patients within the Milan criteria and C-P A cirrhosis. Our results showed the ALBI score significantly influenced the overall survival and cumulative recurrence rates. Furthermore, the ALBI score was significantly related to the degree of liver cirrhosis and serum γ-glutamyl transpeptidase (GGT) concentration in solitary HCC cases within the Milan criteria and C-P A cirrhosis. Additionally, the combination of the ALBI score and serum GGT concentration contributed to the prognosis prediction in this cohort. In conclusion, we externally validated the ALBI grade as a novel biomarker to predict prognosis for solitary HCC within the Milan Criteria and C-P A cirrhosis.

Changes of platelet times neutrophil to lymphocyte ratio predict BCLC stage A hepatocellular carcinoma survival

Platelet, neutrophil, and lymphocyte ratio (PNLR) has its own unique role in influencing postoperative recurrence for patients with hepatocellular carcinoma (HCC). Surgical stress can change systemic inflammatory response of patients. Thus the aim of this study was to identify the prognostic value of changes of platelet times neutrophil to lymphocyte ratio in hepatitis B related HCC within Barcelona clinical liver cancer (BCLC) stage A.Data of patients with HCC within BCLC stage A were reviewed. Pre-, intra- and postoperative variables were retrospectively and statistically analyzed. The postoperative variable was calculated based on the data obtained on the first postoperative month following liver resection.A total of 556 patients were included in present study. During the follow-up period, 257 patients experienced recurrence and 150 patients died. Multivariate analyses suggested multiple tumors (hazard ratio [HR] = 2.409; 95% confidence interval [CI] = 1.649-3.518; P < .001), microvascular invasion (MVI) (HR = 1.585; 95% CI = 1.219-2.061; P = .001), and increased postoperative PNLR (HR = 1.900; 95% CI = 1.468-2.457; P < .001) independently associated with postoperative recurrence, whereas MVI (HR = 1.834; 95% CI = 1.324-2.542; P < .001), postoperative neutrophil to lymphocyte ratio (NLR) (HR = 1.151; 95% CI = 1.025-1.294; P = .018) and increased postoperative PNLR (HR = 2.433; 95% CI = 1.667-3.550; P < .001) contributed to postoperative mortality. The 5-year recurrence-free survival and overall survival rates of patients with increased postoperative PNLR (N = 285) versus those with decreased postoperative PNLR (N = 271) were 36.8% versus 61.5% and 47.6% versus 76.4% respectively (P < .001).Changes of PNLR was a powerful prognostic indicator of poor outcomes in patients with HCC within BCLC stage A. PNLR should be monitored in our postoperative follow-up.

Prognostic value of platelet to lymphocyte ratio in hepatocellular carcinoma: a meta-analysis

This study was designed to evaluate the prognostic value of platelet to lymphocyte ratio (PLR) in hepatocellular carcinoma (HCC). A comprehensive literature search for relevant studies was performed in Web of science, Embase and Pubmed. A total of nine studies with 2017 patients were included in this meta-analysis, and combined hazard ratio (HR) or odds ratio (OR) and 95% confidence intervals (95%CIs) were served as effect measures. Pooled results showed that elevated PLR was associated with poor overall survival (OS) (HR = 1.63, 95%CI: 1.42–1.88, p = 0.000; I² = 0.0%, P_h = 0.637) and poor disease-free survival (DFS)/recurrence-free survival (RFS) (HR=1.32, 95%CI: 1.15–1.52, p = 0.000; I² = 19.3%, P_h = 0.287) in HCC patients. In addition, high PLR was not significantly correlated with the presence of vascular invasion, tumor multifocality, poor tumor grade or high level of serum AFP (>400 ng/ml). In conclusion, elevated PLR indicated a poor prognosis for patients with HCC. PLR may be a reliable, easily-obtained, and low cost biomarker with prognostic potential for HCC.

Neutrophil-to-lymphocyte ratio for the prognostic assessment of hepatocellular carcinoma: A systematic review and meta-analysis of observational studies

BACKGROUND AND AIMS

Neutrophil to lymphocyte ratio (NLR) is an inflammatory-based marker. A systematic review and meta-analysis was performed to explore the prognostic role of NLR in patients with hepatocellular carcinoma (HCC).

RESULTS

Overall, 598 papers were identified, of which 90 papers including 20,475 HCC patients were finally included. Low baseline NLR was significantly associated with better overall survival (HR = 1.80, 95% CI: 1.59-2.04, p < 0.00001) and recurrence-free or disease-free survival (HR = 2.23, 95% CI: 1.80-2.76, p < 0.00001). Low post- treatment NLR was significantly associated with better overall survival (HR = 1.90, 95% CI: 1.22-2.94, p = 0.004). Decreased NLR was significantly associated with overall survival (HR = 2.23, 95%CI: 1.83-2.72, p < 0.00001) and recurrence-free or disease-free survival (HR = 2.23, 95% CI: 1.83-2.72, p < 0.00001). The findings from most of subgroup meta-analyses were consistent with those from the overall meta-analyses.

MATERIALS AND METHODS

All relevant literatures were identified via PubMed, EMBASE, and Cochrane library databases. Hazard ratio (HR) with 95% confidence interval (95%CI) was calculated. Subgroup meta-analyses were performed according to the treatment options, NLR cut-off value ranges, and regions.

CONCLUSIONS

NLR should be a major prognostic factor for HCC patients. NLR might be further incorporated into the prognostic model of HCC.

Cholecystectomy is associated with higher risk of early recurrence and poorer survival after curative resection for early stage hepatocellular carcinoma

Although cholecystectomy has been reported to be associated with increased risk of developing hepatocellular carcinoma (HCC), the association between cholecystectomy and prognosis of HCC patients underwent curative resection has never been examined. Through retrospective analysis of the data of 3933 patients underwent curative resection for HCC, we found that cholecystectomy was an independent prognostic factor for recurrence-free survival (RFS) of patients at early stage (BCLC stage 0/A) (p = 0.020, HR: 1.29, 95% CI: 1.04-1.59), and the 1-, 3-, 5-year RFS rates for patients at early stage were significantly worse in cholecystectomy group than in non-cholecystectomy group (80.5%, 61.8%, 52.0% vs 88.2%, 68.8%, 56.8%, p = 0.033). The early recurrence rate of cholecystectomy group was significantly higher than that of non-cholecystectomy group for patients at early stage (59/47 vs 236/333, p = 0.007), but not for patients at advanced stage (BCLC stage C) (p = 0.194). Multivariate analyses showed that cholecystectomy was an independent risk factor for early recurrence (p = 0.005, HR: 1.52, 95% CI: 1.13-2.03) of early stage HCC, but not for late recurrence (p = 0.959). In conclusion, cholecystectomy is an independent predictor for early recurrence and is associated with poorer RFS of early stage HCC. Removal of normal gallbladder during HCC resection may be avoided for early stage patients.
