Lymphocyte to monocyte ratio and neutrophil to lymphocyte ratio are superior inflammation-based predictors of recurrence in patients with hepatocellular carcinoma after hepatic resection

Machine Learning Model Based on the Neutrophil-to-Eosinophil Ratio Predicts the Recurrence of Hepatocellular Carcinoma After Surgery

Background

Circulating eosinophils are associated with tumor development. An eosinophil-related index, the neutrophil to eosinophil ratio (NER), can be used to predict the prognosis of patients with tumors. However, there is still a lack of efficient prognostic biomarkers for HCC. In this study, we aimed to investigate the predictive value of the NER and develop an optimal machine learning model for the recurrence of HCC patients. Patients and methods: A retrospective collection of 562 patients who underwent hepatectomy with a pathologic diagnosis of HCC was performed. The relationship between NER and progression-free survival (PFS) was investigated. We developed a new machine learning framework with 10 machine learning algorithms and their 101 combinations to select the best model for predicting recurrence after hepatectomy. The performance of the model was assessed by the area under the curve (AUC) of characteristics and calibration curves, and clinical utility was evaluated by decision curve analysis (DCA).

Results

Kaplan‒Meier curves showed that the PFS in the low NER group was significantly better than that in the high NER group. Multivariate Cox regression analysis showed that NER was an independent risk factor for recurrence after surgery. The random survival forests (RSF) model was selected as the best model that had good predictive efficacy and outperformed the TNM, BCLC, and CNLC staging systems.

Conclusion

The NER has good predictive value for postoperative recurrence in patients with hepatocellular carcinoma. Machine learning model based on NER can be used for accurate predictions.

Impact of inflammation and the immune system on hepatocellular carcinoma recurrence after hepatectomy

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death worldwide. Hepatectomy remains the first-line treatment for patients with resectable HCC. However, the reported recurrence rate of HCC at 5 years after surgery is between 50% and 70%. Tumor-related factors, including tumor size, number and differentiation, and underlying liver disease are well-known risk factors for recurrence after treatment. In addition to tumor-related factors, ever-increasing amounts of studies are finding that the tumor microenvironment also plays an important role in the recurrence of HCC, including systemic inflammatory response and immune regulation. Based on this, some inflammatory and immune markers were used in predicting postoperative cancer recurrence. These include neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, cytotoxic T cells, and regulatory T cells, among others. In this review, we summarized the inflammatory and immune markers that affect recurrence after HCC resection in order to provide direction for adjuvant therapy after HCC resection and ultimately achieve the goal of reducing recurrence.

The value of preoperative neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and red blood cell distribution width in predicting positive surgical margin after laparoscopic radical prostatectomy

BACKGROUND

Prostate cancer (PCa) is one of the most common malignant tumors in men, and laparoscopic radical prostatectomy (LRP) is commonly used to treat localized and advanced PCa. Positive surgical margin (PSM) is one of the most frequent problems faced by surgeons.

AIMS

This study aimed to explore the value of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and red blood cell distribution width (RDW) in predicting PSM after LRP.

METHODS AND RESULTS

Three hundred and twenty patients with PCa were admitted and underwent LRP in Beijing Chaoyang Hospital from January 2017 to June 2023. Patients were randomly divided into a training set (225 cases) and a validation set (95 cases) in a 7:3 ratio. NLR, PLR, and RDW were significantly higher in the PSM group than in the negative surgical margins (NSM) group. In addition, the NLR, PLR, and RDW values correlated with clinical T stage, Gleason score, and seminal vesicle invasion in the PSM group. In training set, ROC curve analysis revealed that the optimal cutoff values of NLR, PLR, and RDW for predicting postoperative PSM in PCa were 2.31, 115.40, and 12.85%, respectively. Multivariate Logistic regression analysis showed NLR and RDW were the clinical independent predictors. The area under the curve (AUC, 0.770, 95% CI 0.709-0.831) for postoperative PSM was the highest when a combination of the three parameters was used, with sensitivity and specificity of 62.5% and 85.2%, respectively. In validation set, the AUC values for NLR, PLR, RDW and the three markers combined were 0.708, 0.675, 0.723, and 0.780, respectively. Correlation analysis showed that in the PSM group, NLR was positively correlated with PLR and RDW, and PLR was positively correlated with RDW. By contrast, in the NSM group, a positive association was only found between NLR and PLR.

CONCLUSIONS

Higher preoperative NLR, PLR, and RDW values were associated with postoperative PSM. Additionally, the three markers combined may be useful to predict PSM.

Portal vein tumour thrombosis radiotherapy improves the treatment outcomes of immunotherapy plus bevacizumab in hepatocellular carcinoma: a multicentre real-world analysis with propensity score matching

Background

This study aimed to evaluate the efficacy and safety of sequential immune checkpoint inhibitors (ICIs) plus bevacizumab therapy after radiotherapy for portal vein tumour thrombosis (PVTT) in patients with hepatocellular carcinoma (HCC).

Methods

Retrospective data were collected from 113 patients with HCC with PVTT. Patients in the PVTT radiotherapy (radiotherapy + ICIs + bevacizumab) and control groups (ICIs + bevacizumab) were enrolled according to propensity score matching (PSM) analysis (1:1). The differences in progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and potential factors affecting PFS between the groups were analysed. The adverse events (AEs) were compared between the two groups.

Results

There were 47 patients in the two groups after PSM (1:1). The differences in neutrophil and lymphocyte counts, neutrophil-to-lymphocyte ratio (NLR), CRP, and CD4, CD8, and CD4-to-CD8 ratio before and after radiotherapy for PVTT (P < 0.05) in the PVTT radiotherapy group were significant. The patients in the PVTT radiotherapy group had a longer PFS (median, 9.6 vs. 5.4 months, P < 0.001), and the PFS rates of 3, 6, 9, and 12 months were 97.87% vs. 94.19%, 80.85% vs. 44.68%, 53.19% vs. 6.38%, and 23.40% vs. 0.00%, respectively (P < 0.001). There were also significant differences in the ORR (48.94% vs. 27.66%, P = 0.0339) and DCR (97.87% vs. 82.98%, P = 0.0141) between the two groups, and no serious AEs were observed. Multivariate Cox analysis showed that AFP expression, gross classification of HCC, PVTT type, extrahepatic metastasis, PVTT radiotherapy, and reduction in PVTT were independent factors influencing PFS (P < 0.05).

Conclusions

Sequential ICIs plus bevacizumab therapy after radiotherapy for PVTT in patients with HCC is safe and feasible and may further prolong the PFS of patients.

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.

Determinants of Treatment Benefit and Post-Treatment Survival for Patients with Hepatocellular Carcinoma Enrolled in Second-Line Trials after the Failure of Sorafenib Treatment

Second-line treatments are standard care for advanced hepatocellular carcinoma (HCC) patients with preserved liver function who are intolerant of or progress on first-line therapy. However, determinants of treatment benefit and post-treatment survival (PTS) remain unknown. HCC patients previously treated with sorafenib and enrolled in second-line clinical trials were pooled according to the investigational treatment received and the subsequent regulatory approval: approved targeted agents and immune checkpoint inhibitors (AT) or other agents (OT) not subsequently approved. Univariate and multivariate analyses using Cox proportional hazards models established relationships among treatments received, clinical variables, and overall survival (OS) or PTS. For 174 patients (80 AT; 94 OT) analyzed, baseline factors for longer OS in multivariate analysis were second-line AT, absence of both portal vein thrombosis and extrahepatic spread (EHS). Treatment with AT (versus OT) was associated with significantly longer OS among patients with EHS (pinteraction = 0.005) and patients with low neutrophil-to-lymphocyte ratio (NLR; pinteraction = 0.032). Median PTS was 4.0 months (95% CI 2.8−5.3). At second-line treatment discontinuation, alpha-fetoprotein (AFP) levels <400 ng/dl, albumin-bilirubin (ALBI) grade 1, and enrolment onto subsequent trials independently predicted longer PTS. Treatment with AT, PVT, and EHS were prognostic factors for OS, while AFP, ALBI grade and enrolment onto a third-line trial were prognostic for PTS. Presence of EHS and low NLR were predictors of greater OS benefit from AT.

Prognostic Value of Preoperative Systemic Inflammatory Parameters in Advanced Gastric Cancer

Background: The predictive value of various systemic inflammatory parameters has been reported. However, it is still unclear which inflammatory parameters are the best predictors of prognosis in advanced gastric cancer and what are their mechanisms of action. The aim of this study was to evaluate the association between preoperative systemic inflammatory parameters and overall survival (OS) in patients with advanced gastric cancer. Methods: This retrospective study included 489 patients with stage II/III advanced gastric cancer treated at the National Cancer Center, Republic of Korea, between January 2012 and December 2015. We divided the patients into survivors and non-survivors and compared their clinicopathological characteristics. Univariate and multivariate analyses using the Cox proportional hazards model were performed to evaluate the prognostic value of inflammatory parameters. Results: The absolute lymphocyte count was significantly higher in survivors (2.07 ± 0.62 × 10³/µL vs. 1.88 ± 0.63 × 10³/µL, p = 0.001). The neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) were marginally lower in survivors. Survival analysis revealed that the NLR and PLR were independent prognostic factors for OS. Survival was significantly different depending on NLR and PLR in the same pathologic stages. Conclusions: NLR and PLR were independent prognostic factors for OS in patients with advanced gastric cancer. Regarding single inflammatory parameters, an elevated lymphocyte count was the only factor associated with a favorable prognosis. These results suggest that the enhanced immune function of patients affects their prognosis more than the increased systemic inflammatory response.

Combination of Preoperative Circulating Tumor Cell Count and Neutrophil-Lymphocyte Ratio for Prognostic Prediction in Hepatocellular Carcinoma Patients after Curative Hepatectomy

Background

Both the preoperative neutrophil-lymphocyte ratio (NLR) and circulating tumor cell count (CTC) are associated with poor prognosis in hepatocellular carcinoma (HCC). The purpose of this study was to explore the prognostic value of these two indices (CTC-NLR) in HCC.

Methods

We retrospectively collected demographic and clinical data, including NLR and CTC, from 97 patients with HCC who underwent curative hepatectomy at our institution from March 2014 to May 2017. X-Tile software was used to confirm the optimal cut-off value of NLR and CTC for predicting overall survival (OS) in this study. OS were also analyzed using Kaplan-Meier and Cox regression methods. Based on preoperative CTC and NLR, patients were divided into three groups: CTC-NLR (0), CTC-NLR (1), and CTC-NLR (2). Relationships of CTC-NLR with clinicopathological factors and survival were evaluated.

Results

Preoperatively, CTC positively correlated with NLR. Patients with NLR and CTC higher than the cut-offs had shorter OS than patients with low NLR and CTC. Kaplan-Meier analysis, and log-rank tests revealed significantly lower OS among patients with CTC-NLR scores of 0, 1, and 2. Uni- and multivariate analyses showed that CTC-NLR (hazard ratio 2.050, P = 0.005), CTC (hazard ratio 2.285, P = 0.032), and NLR (hazard ratio 1.902, P = 0.048) were independent predictor of OS. A time-dependent ROC curve indicated that the prognostic efficacy of the CTC-NLR at 1 year (0.714) was better than that of NLR (0.687) and CTC (0.590); the prognostic efficacy of the CTC-NLR at 2 years (0.746) was better than that of NLR (0.711) and CTC (0.601); the prognostic efficacy of the CTC-NLR at 3 years (0.742) was better than that of NLR (0.694) and CTC (0.629).

Conclusions

HCC patients with higher NLR and CTC tend to show shorter OS. Preoperative CTC-NLR may be associated with poor survival and might be a reliable prognostic predictor in HCC after curative hepatectomy.

Preoperative inflammatory markers for predicting parathyroid carcinoma

OBJECTIVE

Parathyroid carcinoma is a rare tumor among parathyroid tumors. Aspiration cytology and needle biopsy are generally not recommended for diagnostic purposes because they cause dissemination. Therefore, it is commonly diagnosed by postoperative histopathological examination. In this study, we investigated whether preoperative inflammatory markers can be used as predictors of cancer in patients with primary hyperparathyroidism.

DESIGN

This was a retrospective study.

METHODS

Thirty-six cases of parathyroid carcinoma and 50 cases of parathyroid adenoma (PA) operated with the diagnosis of primary hyperparathyroidism and confirmed histopathologically at Ito Hospital were included in this study. Preoperative clinical characteristics and inflammatory markers (neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio (LMR)) were compared and their values in preoperative prediction were evaluated and analyzed.

RESULTS

Preoperative intact-parathyroid hormone (P = 0.0003), serum calcium (P = 0.0048), and tumor diameter (P = 0.0002) were significantly higher in parathyroid carcinoma than in PA. LMR showed a significant decrease in parathyroid carcinoma (P = 0.0062). In multivariate analysis, LMR and tumor length diameter were independent predictors. In the receiver operating characteristics analysis, the cut-off values for LMR and tumor length diameter were 4.85 and 28.0 mm, respectively, for parathyroid cancer prediction. When the two extracted factors were stratified by the number of factors held, the predictive ability improved as the number of factors increased.

CONCLUSION

In the preoperative evaluation, a combination of tumor length diameter of more than 28 mm and LMR of less than 4.85 was considered to have a high probability of cancer.

Peritumoral histopathologic findings in patients with chronic viral hepatitis-associated hepatocellular carcinoma

Data on peritumoral histopathologic findings in patients with hepatocellular carcinoma (HCC) is limited. In this retrospective study, we evaluated the peritumoral histopathologic changes in patients with chronic viral hepatitis (CVH)-associated HCC (CVH-HCC) and their prognostic value. 61 consecutive cirrhotic patients who underwent liver transplantation due to CVH-HCC were included. Histopathologic features within 1 cm distance of the tumor, and their association with clinicopathological characteristics and prognosis were evaluated. A random representative slide of cirrhotic parenchyma unrelated to invasive and/or dysplastic foci was also evaluated for the same histopathologic criteria. The majority (85%, n = 52) were male with a median age of 55 ± 6.38 (range, 39-67). The etiologic agent was only HBV in 90% (n = 55). The most common peritumoral findings were portal inflammation (100%; n = 61), ductular reaction (100%; n = 61) and sinusoidal dilatation (95%; n = 58). Macrovascular invasion was observed only in four cases (7%) with mild peritumoral portal inflammation. Neutrophilic infiltration of the peritumoral portal tracts (n = 18; 30%) was significantly associated with pT4 tumor stage, tumor grade, macrovascular invasion, and pretransplant therapy. Patients with moderate or severe peritumoral sinusoidal dilatation tended to have worse prognosis, albeit not significantly. Peritumoral ballooning degeneration was associated with multifocality, recurrence and recurrence-free survival in both uni- and multivariate analysis. Peritumoral histopathologic changes in CVH-HCC can be classified as: changes related to pathogenesis, changes indirectly affecting prognosis, and changes directly affecting prognosis. Peritumoral prominent ballooning degeneration may be a predictor of recurrence while portal neutrophilic infiltration and sinusoidal dilatation seem to indicate poor prognosis.

Correlation between the Lymphocyte-To-Monocyte Ratio (LMR) and Child–Pugh and MELD/MELDNa Scores in Vietnamese Patients with Liver Cirrhosis

Objectives: This study aims to determine cirrhotic patients’ clinical and laboratory characteristics, thereby examining the correlation between lymphocyte-to-monocyte ratio and Child–Pugh and MELD/MELDNa scores. Methods: A cross-sectional study with an analysis of 153 patients admitted to the Department of Gastroenterology–Clinical Hematology at Can Tho Central General Hospital. Data were collected via patient interviews and medical records. Results: The included patients were more likely to be male (66.7%) and were ≥60 years old (51.6%). Excessive alcohol consumption and hepatitis B were the dominant causes of cirrhosis (35.3% and 34.0%). The clinical and laboratory characteristics were similar to previous studies in cirrhotic patients. The mean Child score was 9.3 ± 2.1, including 9.8% of patients with Child A, 44.4% for Child B, and 45.8% for Child C. The mean MELD and MELDNa scores were 16.9 ± 7.1 and 19.4 ± 8.1, respectively. The mean lymphocyte-to-monocyte ratio (LMR) is 2.0 ± 2.2 (from 0.09 to 25.3), being negatively correlated with the other scores (Pearson correlation coefficients were −0.238; −0.211 and −0.245, respectively, all p-values < 0.01). Patients with LMR below 3.31 were more likely to be classified as Child–Pugh B and C. Conclusion: The correlation between LMR with Child–Pugh, MELD, and MELDNa scores was weak and negative.

Combination of Tertiary Lymphoid Structure and Neutrophil-to-Lymphocyte Ratio Predicts Survival in Patients With Hepatocellular Carcinoma

Background

Hepatocellular carcinoma (HCC) is the most common pathological type of primary liver cancer. The lack of prognosis indicators is one of the challenges in HCC. In this study, we investigated the combination of tertiary lymphoid structure (TLS) and several systemic inflammation parameters as a prognosis indicator for HCC.

Materials and Methods

We retrospectively recruited 126 postoperative patients with primary HCC. The paraffin section was collected for TLS density assessment. In addition, we collected the systemic inflammation parameters from peripheral blood samples. We evaluated the prognostic values of those parameters on overall survival (OS) using Kaplan-Meier curves, univariate and multivariate Cox regression. Last, we plotted a nomogram to predict the survival of HCC patients.

Results

We first found TLS density was positively correlated with HCC patients’ survival (HR=0.16, 95% CI: 0.06 − 0.39, p < 0.0001), but the power of TLS density for survival prediction was found to be limited (AUC=0.776, 95% CI:0.772 − 0.806). Thus, we further introduced several systemic inflammation parameters for survival analysis, we found neutrophil-to-lymphocyte ratio (NLR) was positively associated with OS in univariate Cox regression analysis. However, the combination of TLS density and NLR better predicts patient’s survival (AUC=0.800, 95% CI: 0.698-0.902, p < 0.001) compared with using any single indicator alone. Last, we incorporated TLS density, NLR, and other parameters into the nomogram to provide a reproducible approach for survival prediction in HCC clinical practice.

Conclusion

The combination of TLS density and NLR was shown to be a good predictor of HCC patient survival. It also provides a novel direction for the evaluation of immunotherapies in HCC.

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.

Update on perioperative management of patients undergoing surgery for liver cancer

Hepatocellular carcinoma is often accompanied by chronic hepatitis or cirrhosis. Preoperative evaluation of liver function and postoperative nutritional management are critical in patients with hepatocellular carcinoma who undergo liver surgery. Although the incidence of postoperative complications and death has declined in Japan over the last 10 years, postoperative complications have not been fully overcome. Therefore, surgical procedures and perioperative management must be improved. Accurate preoperative evaluations of liver function, nutrition, inflammation, and body skeletal muscle are required. Determination of the optimal surgical procedure should consider not only tumor characteristics but also the physical reserve of the patient. Nutritional management of chronic liver disorders, especially maintaining protein synthesis for postoperative protein/energy, is important. Prophylactic antibiotics are recommended for short‐term use within 24 hours after surgery. Abdominal drainage is recommended for patients with cirrhosis who may develop large amounts of ascites, who are at risk of postoperative bleeding, or who may have bile leakage due to a large resection area. Postoperative exercise therapy may improve insulin resistance in patients with chronic liver damage. Implementation of an early/enhanced recovery after surgery program is recommended to reduce biological invasive responses and achieve early independence of physical activity and nutrition intake. We review the latest information on the perioperative management of patients undergoing liver resection for hepatocellular carcinoma.

Serum Inflammation-based Scores in Endocrine Tumors

CONTEXT

Serum inflammation-based scores reflect systemic inflammatory response and/or patients' nutritional status, and may predict clinical outcomes in cancer. While these are well-described and increasingly used in different cancers, their clinical usefulness in the management of patients with endocrine tumors is less known.

EVIDENCE ACQUISITION

A comprehensive PubMed search was performed using the terms "endocrine tumor," "inflammation," "serum inflammation-based score," "inflammatory-based score," "inflammatory response-related scoring," "systemic inflammatory response markers," "neutrophil-to-lymphocyte ratio," "neutrophil-to-platelet ratio," "lymphocyte-to-monocyte ratio," "Glasgow prognostic score," "neutrophil-platelet score," "Systemic Immune-Inflammation Index," and "Prognostic Nutrition Index" in clinical studies.

EVIDENCE SYNTHESIS

The neutrophil-to-lymphocyte ratio and the platelet-to-lymphocyte ratio are the ones most extensively investigated in patients with endocrine tumors. Other scores have also been considered in some studies. Several studies focused in finding whether serum inflammatory biomarkers may stratify the endocrine tumor patients' risk and detect those at risk for developing more aggressive and/or refractory disease, particularly after endocrine surgery.

CONCLUSIONS

In this review, we summarize the current knowledge on the different serum inflammation-based scores and their usefulness in predicting the phenotype, clinical aggressiveness, and disease outcomes and prognosis in patients with endocrine tumors. The value of such serum inflammation-based scores in the management of patients with endocrine tumors has been emerging over the last decade. However, further research is necessary to establish useful markers and their cut-offs for routine clinical practice for individual diseases.

Prognostic Impact of Monocyte to Lymphocyte Ratio in Clinical Outcome of Patients with Hepatocellular Carcinoma: A Systematic Review and Meta-analysis

Background:

Lymphocyte to monocyte ratio (LMR) is a surrogate marker of systemic inflammation which is shown to be related to the patient’s survival in multiple malignancies. An important implication of this marker potentially is neoplasms in which there is no correlation between prognosis and histopathological staging and also has no reliable chemical markers associated with prognosis. Herein, this meta-analysis aimed to investigate the prognostic role of LMR in patients with hepatocellular carcinoma (HCC).

Materials and Methods:

In the current systemic review and meta-analysis, we conducted a systemic search of databases and indexing sources, including PubMed, EMBASE, Cochrane, Scopus, and ProQuest up to May 2019 toinclude studies on the prognostic significance of LMR on patients with HCC. Overall survival (OS), disease-free survival (DFS) and recurrence-free survival (RFS) values were extracted from the studies and analyzed. The pooled hazard ratio with a 95% confidence interval was explored to identify the prognostic value of the LMR in the survival of the patients with HCC.

Results:

A total of 12 studies with a total sample size of 3750 cases were included. There was significant heterogeneity among the studies; therefore, subgroup analysis was also performed. Overall analysis regarding OS showed an insignificant relationship between LMR and patient’s prognosis, dividing to subgroups based on LMR cut-offs did not yield any significant result, subgroup analysis for RFS founded statistically significant results and LMR was significantly related to DFS.

Conclusion:

High LMR was associated with increased DFS and RFS, in return this association was not observed for OS.

Lymphocyte-to-C-reactive protein ratio as a prognostic factor for hepatocellular carcinoma

BACKGROUND

Systemic inflammation has been correlated with worse survival for some cancers. We evaluated prognostic values of various inflammatory factor combinations in patients who underwent resections for hepatocellular carcinoma (HCC).

METHODS

We retrospectively analysed 306 consecutive patients with HCC who underwent curative liver resections. After assessing eight combinations of inflammatory markers for predictive value for recurrence, we focused on lymphocyte-to-C-reactive protein ratio (LCR) to elucidate its associations with recurrence-free survival (RFS) and overall survival (OS) in univariate and multivariate analyses (Cox proportional hazards model). We also used immunohistochemical CD34 and CD8 staining to investigate the mechanism of LCR elevation.

RESULTS

LCR showed the highest association with RFS in HCC patients among the compared indices. High preoperative LCR correlated with a high serum albumin concentration, small tumour size, early Barcelona Clinic Liver Cancer stage and low rates of microscopic vascular invasion and microscopic intrahepatic metastasis. Higher preoperative LCR was an independent predictor of longer RFS and OS in this cohort. High LCR patients had fewer vessels encapsulating tumour clusters, and higher intratumoural CD8⁺ T-cell counts than low LCR patients.

CONCLUSIONS

Preoperative LCR is a novel and convenient prognostic marker for patients with HCC, and is associated with the tumour microenvironment immune status.

Pre-operative serum inflammation-based scores in patients with pituitary adenomas

OBJECTIVE

Full blood count (FBC) and serum inflammation-based scores reflect systemic inflammation and predict outcomes in cancer, but little is known in pituitary adenomas (PAs). We aimed to characterise FBC and inflammation-based scores in PA patients and investigate their usefulness in predicting challenging disease course.

METHODS

We studied 424 PA patients first operated at our centre with available pre-operative biochemical data. Patients with infection, malignancies, autoimmune or haematological conditions were excluded. Inflammation-based scores studied: Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR), Lymphocyte-to-Monocyte Ratio (LMR), Systemic Immune-Inflammation Index (SII), Neutrophil-Platelet Score (NPS), Prognostic Nutrition Index (PNI), and Glasgow Prognostic Score (GPS).

RESULTS

Cushing's disease patients had more platelets, leucocytes, neutrophils and monocytes, and higher NLR, NPS and SII. Serum inflammation-based scores didn't differ among non-Cushing PA subtypes. The glucocorticoid excess severity influenced leucocyte, eosinophil, basophil and platelet counts, and GPS in Cushing's disease. Patients with functioning non-Cushing PAs with suprasellar extension, cavernous sinus invasion and hypopituitarism had GPS ≥ 1, while NPS ≥ 1 was associated with suprasellar extension. More invasive and difficult to treat corticotrophinomas were associated with fewer platelets pre-operatively (< 299.5 × 10⁹/L predicting multimodal treatment). Non-functioning PA patients who suffered apoplexy had more leucocytes, neutrophils and monocytes, higher GPS ≥ 1 and fewer platelets; re-operated cases had fewer lymphocytes, higher NLR and PLR.

CONCLUSIONS

Serum inflammation-based scores may predict invasive/refractory PAs: GPS and PNI in non-functioning and functioning non-Cushing PAs; NPS in functioning non-Cushing PAs; NLR and PLR in non-functioning PAs. Platelets < 299.5 × 10⁹/L predict multimodal treatment in Cushing's disease. Further studies are needed to confirm these observations.

Hyperprogressive disease during PD-1 blockade in patients with advanced hepatocellular carcinoma

BACKGROUND & AIMS

Programmed cell death-1 (PD-1) inhibitor treatment can cause hyperprogressive disease (HPD), but the incidence, outcome, and predictive factors of HPD are unknown in patients with hepatocellular carcinoma (HCC). Herein, we assessed the existence and factors predictive of HPD in patients with advanced HCC treated with nivolumab.

METHODS

We enrolled 189 patients with advanced HCC treated with nivolumab. Occurrence of HPD was investigated using tumour growth dynamics based on tumour growth kinetics (TGK) and tumour growth rate (TGR) before and after treatment, or time to treatment failure. We additionally analysed patients treated with regorafenib (n = 95) or best supportive care (BSC)/placebo (n = 103) after progression on sorafenib to compare tumour growth dynamics.

RESULTS

Flare-up of tumour growth was observed in a fraction of patients upon PD-1 blockade, indicating the occurrence of HPD. Based on distinct patterns of disease progression exclusively observed in the nivolumab-treated cohort, but not in the regorafenib- or BSC/placebo-treated cohorts, 4-fold increases in TGK and TGR ratios as well as a 40% increase in TGR were the cut-off values used to define HPD; 12.7% of the patients (24/189) treated with nivolumab met all these criteria. Patients with HPD had worse progression-free survival (hazard ratio [HR] 2.194; 95% CI 1.214-3.964) and overall survival (HR 2.238; 95% CI 1.233-4.062) compared to patients with progressive disease without HPD. More than 90% of patients with HPD missed the opportunity for subsequent treatment because of rapid clinical deterioration. An elevated neutrophil-to-lymphocyte ratio (>4.125) was associated with HPD and an inferior survival rate.

CONCLUSIONS

HPD occurs in a fraction of patients with HCC who receive PD-1 inhibitor treatment. Analyses of the baseline immune profile and on-treatment tumour growth dynamics could enable optimal patient selection and earlier identification of HPD.

LAY SUMMARY

Hyperprogressive disease is an unexpected response pattern observed in patients treated with an immune checkpoint inhibitor. This study revealed that hyperprogressive disease occurs in a fraction of patients with advanced hepatocellular carcinoma treated with an anti-PD-1 antibody, providing evidence to encourage careful monitoring of patients to prevent clinical deterioration induced by PD-1 blockade.

Clinicopathological and prognostic value of preoperative lymphocyte to monocyte ratio for hepatocellular carcinoma following curative resection: A meta-analysis including 4,092 patients

BACKGROUND

Previous studies have reported that lymphocyte-to-monocyte ratio (LMR) had novel prognostic value in hepatocellular carcinoma (HCC). The purpose of this meta-analysis was to synthetically evaluate the prognostic role of preoperative LMR in HCC patients following curative resection.

METHODS

Eligible studies were acquired through searching Pubmed, Web of Science, Cochrane Library and EMbase update to September 2019. Merged hazard ratios (HRs) and 95% confidence intervals (CIs) were applied as effect sizes.

RESULTS

A total of ten studies containing 4,092 patients following liver resection were enrolled in this meta-analysis. The pooled results demonstrated that preoperative elevated LMR indicated superior survival outcome (HR: 0.58, 95% CI: 0.34-0.96, P = .035) and recurrence-free survival (RFS)/disease-free survival/time to recurrence (HR = 0.76, 95% CI: 0.58-0.98, P = .034). The significant prognostic role of preoperative LMR was detected in the subgroup of all publication year, country of origin, sample sizes <300, TNM stage of I-IV and LMR cut-off value ≤4. Furthermore, high LMR was significantly associated with male, high AFP, large tumor size, incomplete tumor capsule, advanced TNM stage and BCLC stage, and presence of PVTT.

CONCLUSION

Elevated preoperative LMR indicated superior survival outcome in HCC patients following curative resection, and might serve as a novel prognostic biomarker.

Clinical impact of anatomical resection on long-term outcomes after hepatectomy for primary solitary hepatocellular carcinoma with or without preoperative positron emission tomography positivity

Background

There is little evidence indicating that anatomical resection (AR) is associated with improved survival in patients with solitary hepatocellular carcinoma (HCC) who were preoperatively evaluated by positron emission tomography (PET). The aim of our study was to compare the oncologic outcomes of AR in PET-positive versus PET-negative patients with HCC.

Methods

From January 2007 to September 2015, 259 patients with preoperative PET underwent hepatectomy as the primary treatment for solitary HCC. Patients were divided into four groups according to PET uptake and hepatectomy type [AR or non-anatomical resection (NAR)]: Group 1 (PET-negative and AR, n=62); Group 2 (PET-negative and NAR, n= 46); Group 3 (PET-positive and AR, n=100); Group 4 (PET-positive and NAR, n=51).

Results

PET positivity was associated with higher protein induced by vitamin K antagonist-II (P=0.025), lager tumor size (P=0.05), microvascular invasion (MVI) (P=0.012), and portal vein invasion (P=0.031). In Kaplan-Meier analysis for RFS, Group 1 showed remarkable difference from Group 3 and Group 4 (P=0.045, P=0.023, respectively). In the PET-positive subgroup with HCC under 3 cm, AR was associated with better RFS than NAR (P=0.016).

Conclusions

A combination of AR and PET negativity showed good prognosis in long-term outcomes. Finally, AR can decrease the risk of tumor recurrence in patients with a solitary PET-positive HCC less than 3 cm.

Neutrophil to lymphocyte ratio and albumin bilirubin grade in hepatocellular carcinoma: A systematic review

BACKGROUND

Hepatocellular carcinoma (HCC) is a frequent cause of cancer related death globally. Neutrophil to lymphocyte ratio (NLR) and albumin bilirubin (ALBI) grade are emerging prognostic indicators in HCC.

AIM

To study published literature of NLR and ALBI over the last five years, and to validate NLR and ALBI locally in our centre as indicators of HCC survival.

METHODS

A systematic review of the published literature on PubMed of NLR and ALBI in HCC over the last five years. The search followed the guidelines of the preferred reporting items for systematic reviews and meta-analyses. Additionally, we also investigated HCC cases between December 2013 and December 2018 in our centre.

RESULTS

There were 54 studies describing the relation between HCC and NLR and 95 studies describing the relation between HCC and ALBI grade over the last five years. Our local cohort of patients showed NLR to have a significant negative relationship to survival (P = 0.011). There was also significant inverse relationship between the size of the largest HCC nodule and survival (P = 0.009). Median survival with alpha fetoprotein (AFP) < 10 KU/L was 20 mo and with AFP > 10 KU/L was 5 mo. We found that AFP was inversely related to survival, this relationship was not statically significant (P = 0.132). Mean survival for ALBI grade 1 was 37.7 mo, ALBI grade 2 was 13.4 months and ALBI grade 3 was 4.5 mo. ALBI grades performed better than Child Turcotte Pugh score in detecting death from HCC.

CONCLUSION

NLR and ALBI grade in HCC predict survival better than the conventional alpha fetoprotein. ALBI grade performs better than Child Turcotte Pugh score. These markers are done as part of routine clinical care and in cases of normal alpha fetoprotein, these markers could give a better understanding of the patient disease progression. NLR and ALBI grade could have a role in modified easier to learn staging and prognostic systems for HCC.

Leucocyte ratios are biomarkers of mortality in patients with acute decompensation of cirrhosis and acute-on-chronic liver failure

BACKGROUND

In patients with cirrhosis, progression to acute decompensation (AD) and acute-on-chronic liver failure (ACLF) has been associated with poor prognosis. Differential leucocyte ratios might predict mortality in systemic inflammatory conditions.

AIM

To evaluate differential leucocyte ratios as prognostic biomarkers in patients with cirrhosis.

METHODS

Patients with AD and ACLF were recruited from four centres in three countries. Peripheral blood differential leucocytes were measured (three centres using flow cytometry) on hospital admission and at 48 hours. Ratios were correlated to model for end-stage liver disease (MELD), chronic liver failure-sequential organ failure (CLIF-SOFA), suspected/culture-positive bacterial infection and survival.

RESULTS

Nine hundred twenty-six patients (562 (61%) male, median age 55 (25-94) years) were studied. Overall, 350 (37%) did not survive to hospital discharge. Neutrophil-lymphocyte ratio (NLR) and monocyte-lymphocyte ratio (MLR) were elevated in patients with AD and ACLF who died during their hospital stay. On multivariate analysis NLR retained statistical significance independently of CLIF-SOFA or MELD. NLR >30 was associated with an 80% 90-day mortality in patients with ACLF but not AD. On sensitivity analysis for subgroups (alcohol-related liver disease and suspected sepsis), NLR and MLR retained statistically robust accuracy for the prediction of mortality. Significant predictive accuracy was only observed in centres using flow cytometry.

CONCLUSION

Leucocyte ratios are simple and robust biomarkers of outcome in ACLF, which are comparable to CLIF-SOFA score but dependent on leucocyte quantification method. NLR and MLR may be used as screening tools for mortality prediction in patients with acutely deteriorating cirrhosis.

Novel Models Predict Postsurgical Recurrence and Overall Survival for Patients with Hepatitis B Virus-Related Solitary Hepatocellular Carcinoma ≤10 cm and Without Portal Venous Tumor Thrombus

BACKGROUND

The predictive model of postsurgical recurrence for solitary early hepatocellular carcinoma (SE-HCC) is not well established. The aim of this study was to develop a novel model for prediction of postsurgical recurrence and survival for patients with hepatitis B virus (HBV)-related SE-HCC ≤10 cm.

PATIENTS AND METHODS

Data from 1,081 patients with HBV-related SE-HCC ≤10 cm who underwent curative liver resection from 2003 to 2016 in our center were collected retrospectively and randomly divided into the derivation cohort (n = 811) and the internal validation cohort (n = 270). Eight hundred twenty-three patients selected from another four tertiary hospitals served as the external validation cohort. Postsurgical recurrence-free survival (RFS) and overall survival (OS) predictive nomograms were generated. The discriminatory accuracies of the nomograms were compared with six conventional hepatocellular carcinoma (HCC) staging systems.

RESULTS

Tumor size, differentiation, microscopic vascular invasion, preoperative α-fetoprotein, neutrophil-to-lymphocyte ratio, albumin-to-bilirubin ratio, and blood transfusion were identified as the risk factors associated with RFS and OS. RFS and OS predictive nomograms based on these seven variables were generated. The C-index was 0.83 (95% confidence interval [CI], 0.79-0.87) for the RFS-nomogram and 0.87 (95% CI, 0.83-0.91) for the OS-nomogram. Calibration curves showed good agreement between actual observation and nomogram prediction. Both C-indices of the two nomograms were substantially higher than those of the six conventional HCC staging systems (0.54-0.74 for RFS; 0.58-0.76 for OS) and those of HCC nomograms reported in literature.

CONCLUSION

The novel nomograms were shown to be accurate at predicting postoperative recurrence and OS for patients with HBV-related SE-HCC ≤10 cm after curative liver resection.

IMPLICATIONS FOR PRACTICE

This multicenter study proposed recurrence or mortality predictive nomograms for patients with hepatitis B virus-related solitary early hepatocellular carcinoma ≤10 cm after curative liver resection. A close postsurgical surveillance protocol and adjuvant therapy should be considered for patients at high risk of recurrence.

High lymphocyte‑to‑monocyte ratio is associated with low α‑fetoprotein expression in patients with hepatitis B virus‑associated hepatocellular carcinoma

The association of the peripheral lymphocyte‑to‑monocyte ratio (LMR) with α‑fetoprotein (AFP) status in patients with AFP‑positive and AFP‑negative hepatocellular carcinoma (HCC) has not been investigated in detail. The aim of the present study was to examine the association between the LMR and AFP status in these patients. The samples were obtained from patients with a hepatitis B virus (HBV) infection, who were negative for non‑HBV hepatitis viruses and who did not suffer from autoimmune hepatitis. These patients were retrospectively reviewed and the differences of test indicators in the AFP‑negative and AFP‑positive groups were assessed. Flow cytometry was used to detect the expression levels of CD4, CD8 and programmed cell death protein 1 (PD‑1), and ELISAs were used to analyze the expression levels of interleukin (IL)‑10 and transforming growth factor (TGF)‑β1. In addition, luciferase reporter assays were used to assess binding of the IL‑10 promoter to the glucocorticoid receptor (GR) gene. Receiver operating characteristic curve and Spearman correlation analyses demonstrated that the AFP‑negative HCC group exhibited a higher LMR, lower D‑dimer and lower fibrin degradation products compared with the AFP‑positive HCC group. The cut‑off value of the LMR was 2.01 for AFP detection, with a sensitivity of 68.6% and a specificity of 75%. The high LMR noted in the AFP‑negative HCC group was accompanied by a lower proportion of CD4+ T lymphocytes and CD8‑PD‑1 expression compared with the corresponding levels of these parameters in the AFP‑positive HCC group. Furthermore, the high levels of IL‑10 and low levels of TGF‑β1 were expressed in the AFP‑positive HCC group. The data indicated that the IL‑10‑592 promoter exhibited a potent induction of luciferase activity in 293T cells cotransfected with a GR‑overexpressing vector compared with the control cells. However, the relative luciferase activity was not altered following a mutation or polymorphism in the IL‑10 gene. These results suggested that a high LMR was indicative of low AFP expression in HBV‑associated HCC patients.

Perioperative blood transfusion has distinct postsurgical oncologic impact on patients with different stage of hepatocellular carcinoma

Background

The influence of perioperative blood transfusion (PBT) on postsurgical survival of patients with different stage of hepatocellular carcinoma (HCC) is not well clarified. This study aimed to evaluate the impact of PBT on survival outcomes of different stage of HCC patients.

Methods

Consecutive patients who underwent liver resection for HCC between January 2009 and November 2015 were identified from an HCC prospective database in authors’ center. The survival outcomes were compared between patients receiving PBT and those without PBT before and after propensity score matching (PSM) in different stage subsets. Cox regression analysis was performed to verify the impact of PBT on outcomes of HCC.

Results

Among 1255 patients included, 804 (64.1%) were Barcelona Clinic Liver Cancer (BCLC) stage 0-A, and 347 (27.6%) received PBT. Before PSM, patients with PBT had worse disease free survival (DFS) and overall survival (OS) compared with those without PBT in both BCLC 0-A subset and BCLC B-C subset (all P < 0.05). After PSM, 288 pairs of patients (with and without PBT) were created. In the subset of BCLC 0-A, the median DFS of patients with PBT was shorter than those without PBT (12.0 months vs. 36.0 months, P = 0.001) Similar result was observed for OS (36.0 months vs. 96.0 months, P = 0.001). In the subset of BCLC B-C, both DFS and OS were comparable between patients with PBT and those without PBT. Cox regression analysis showed that PBT involved an increasing risk of DFS (HR = 1.607; P < 0.001) and OS (HR = 1.756; P < 0.001) for this subset. However, PBT had no impact on DFS (P = 0.126) or OS (P = 0.139) for those with stage B-C HCC.

Conclusions

PBT negatively influenced oncologic outcomes of patient with BCLC stage 0-A HCC, but not those with stage B-C after curative resection.

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.

Revealing the prognostic landscape of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in metastatic castration-resistant prostate cancer patients treated with abiraterone or enzalutamide: a meta-analysis

BACKGROUND

The neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR), as markers of systematic inflammation response, have been reported to be indicators in metastatic castration-resistant prostate cancer (mCRPC), whereas their prognostic values remain conflict. This study was to assess the prognostic value of NLR and PLR in mCRPC patients and to assess the response of abiraterone or enzalutamide through using NLR and PLR.

METHODS

Databases searching was conducted in the PubMed, EMBASE, Google Scholar, and the Cochrane Library for relevant published literature up to October 2019. Data extraction and quality evaluation were performed on the eligible studies. STATA 14.0 software was used to pooled hazard ratios (HRs) and their 95% confidence intervals (CIs) for overall survival (OS) and progression-free survival (PFS).

RESULTS

A total of 3144 mCRPC patients were enrolled from 15 cohort studies in this meta-analysis. The pooled results demonstrated that elevated NLR had a significant association with inferior OS in mCRPC patients treated with abiraterone (HR = 1.63, 95% CI: 1.43-1.85, P < 0.001) and enzalutamide (HR = 1.48, 95% CI: 1.27-1.72, P < 0.001), whereas elevated NLR had no significant association with unfavorable PFS treated with abiraterone and enzalutamide, respectively. Elevated PLR had a significant association with an inferior OS (HR = 1.52, 95% CI: 1.16-1.98, P < 0.001) in mCRPC patients treated with abiraterone.

CONCLUSIONS

NLR and PLR were effective biomarkers for predicting prognosis in mCRPC patients and served as indicators of the efficacy of personalized treatment of mCRPC using abiraterone or enzalutamide. Future, more randomized control trials (RCTs) are needed to investigate the promising value of hematologic parameters.

Comparison of the prognostic value of inflammation-based scores in early recurrent hepatocellular carcinoma after hepatectomy

BACKGROUND & AIMS

Inflammation-based prognostic scores, such as the Glasgow Prognostic Score (GPS), modified Glasgow Prognostic Score (mGPS), Prognostic Index (PI), Prognostic Nutritional Index (PNI), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR) and systemic immune-inflammation index (SII), are correlated with the survival of hepatocellular carcinoma (HCC) patients, while remain unclear for recurrent HCC. This study aimed to compare the prognostic value of inflammation-based prognostic scores for post-recurrence survival (PRS) in patients with early recurrent HCC (ErHCC, within 2 years after hepatectomy).

METHODS

A total of 580 patients with ErHCC were enrolled retrospectively. The association between the independent baseline and the time-dependent variables and PRS was evaluated by cox regression. The prediction accuracy of the inflammation-based prognostic scores was assessed by time-dependent receiver operating characteristic (ROC) and Harrell's concordance index (C-index) analyses.

RESULTS

The GPS, mGPS, PI, PNI, NLR, PLR, LMR and SII were all related to the PRS of ErHCC patients, while only the SII (P < .001) remained an independent predictor for PRS in multivariate analysis (hazard ratio: 1.92, 95% confidence interval: 1.33-2.79). Both the C-index of the SII (0.65) and the areas under the ROC curves showed that the SII score was superior to the other inflammation-based prognostic scores for predicting the PRS of ErHCC patients.

CONCLUSIONS

The SII is a useful prognostic indicator for PRS in patients with ErHCC after hepatectomy and is superior to the other inflammation-based prognostic scores in terms of prognostic ability.

Prognostic Value Of The Preoperative Neutrophil To Lymphocyte Ratio In Patients With Sinonasal Squamous Cell Carcinoma

Objective

This study explored the effectiveness of a new inflammatory prognostic system, using preoperative neutrophil to lymphocyte ratio (NLR) to predict the postoperative survival rate of patients with sinonasal squamous cell carcinoma (SSCC).

Methods

Patients diagnosed with SSCC who undergone surgically treated without neoadjuvant therapy were included in the study between May 2008 and October 2017. Preoperative NLR is defined as: preoperative neutrophil/postoperative lymphocyte ratio. The prognostic value was uncovered by univariate and multivariate Cox hazards analysis.

Results

A total of 147 patients were included in this study. Through the multivariate analysis, pathological T stage (hazard ratio [HR] 1.719, confidence interval [CI] 1.277–3.642, p<0.001), pathological N stage (HR 1.344, 95% CI 1.015–2.776, p<0.001), and preoperative NLR (HR 1.579, 95% CI 1.217–3.092, p=0.002) were independent risk factor for overall survival (OS). Pathological T stage (HR 1.835, 95% CI 1.141–3.132, <0.001), pathological N stage (HR 1.281, 95% CI 1.169–2.476, p<0.001), and preoperative NLR (HR 1.688, 95% CI 1.162–3.363, p p<0.001) were also independently associated with disease-free survival (DFS). Pathological T stage (HR p<0.001, 95% CI 1.537–3.021, p<0.001), pathological N stage (HR1.571, 95% CI 1.157–2.258, p<0.001), and preoperative NLR (HR 1.509, 95% CI 1.153–3.104, p=0.001) were independent risk factors for disease-specific survival (DSS).

Conclusion

The preoperative NLR is considered to be a useful predictor of postoperative survival in SSCC patients.

Prognostic impact of neutrophil-to-lymphocyte ratio in cirrhosis: A propensity score matching analysis with a prespecified cut-point

BACKGROUND & AIMS

An elevated neutrophil-to-lymphocyte ratio (NLR) has received attention as a prognostic surrogate across chronic liver diseases. However, an exact threshold has not been fully elucidated.

METHODS

A total number of 589 patients with cirrhosis (LC) were included. The value of NLR was calculated and its optimal cut-off was initially determined by X-tile program. Independent predictors of 90-day mortality were identified with Cox regression model. The Kaplan-Meier method was used to generate survival curves. To reduce influences of selection bias and possible confounders, a 1:2 propensity score matching (PSM) was performed.

RESULTS

The X-tile indicated that the difference in survival was most significant for NLR more than 8.9. Serum NLR > 8.9 was an independent indicator in the entire cohort and PSM subset (HR 4.268, 95% CI 2.211-8.238, P < .001; HR 4.209, 95% CI 1.448-12.238, P = .008 respectively). Subgroup analysis showed that NLR > 8.9 was an independent risk factor of 90-day mortality regardless of age, gender, CTP or MELD score.

CONCLUSIONS

The value of NLR more than 8.9 is a feasible cut-off across clinical settings among applicable population. The adding of NLR to other conventional predictive systems has the potential to provide incremental value without extra economic cost.

Verification of inflammation-based prognostic marker as a prognostic indicator in hepatocellular carcinoma

AIM

Although inflammation-based markers in cancer have been used for prognostic prediction, the most useful marker for hepatocellular carcinoma (HCC) has not been established. We investigated the usefulness of various inflammation-based markers in HCC patients after hepatectomy.

METHODS

A total of 478 patients who underwent initial hepatectomy for HCC from 2009 to 2015 and were diagnosed with pathological HCC were included in this retrospective study. Inflammation-based markers consisted of the C-reactive protein to albumin ratio (CAR), Glasgow prognostic score (GPS), neutrophil to lymphocyte ratio, lymphocyte to monocyte ratio, platelet to lymphocyte ratio and prognostic index. Univariate and multivariate analyses for overall survival (OS) and disease-free survival (DFS) using the Cox proportional hazard model were carried out. Kaplan-Meier analysis and log-rank test were used for comparison of OS and DFS. To reduce influences of selection bias and confounders for stratifying CAR, clinicopathological characteristics of patients were balanced by propensity score matching.

RESULTS

Multivariate analysis identified only high CAR (>0.027) as an indicator of poor OS, and high CAR and high GPS (1-2) as indicators of poor DFS among inflammation-based markers. After propensity score matching, 124 patients each with low CAR and high CAR were matched. High CAR was correlated with both poor OS and DFS.

CONCLUSION

C-reactive protein to albumin ratio was the most valuable prognostic indicator after hepatectomy for HCC among inflammation-based markers.

Preoperative neutrophil-lymphocyte ratio predicts the risk of microvascular invasion in hepatocellular carcinoma: A meta-analysis

BACKGROUND

Preoperative estimation of microvascular invasion is of great significance for the clinical decision making in hepatocellular carcinoma. Neutrophil-lymphocyte ratio (NLR) has been reported to be correlated with the poor prognosis of hepatocellular carcinoma. However, the conclusions are conflicting on whether high preoperative NLR level is associated with the presence of microvascular invasion.

AIM

To evaluate the association between preoperative NLR level and the risk of microvascular invasion in hepatocellular carcinoma.

METHODS

Relevant studies were identified by searching PubMed and Embase through February 2019. Fixed or random models were applied to analyze the data based on the heterogeneity. Subgroup, sensitivity, and publication bias analyses were performed. Review Manager 5.3 and STATA software were used for the meta-analysis.

RESULTS

A total of 15 studies were eventually included in this meta-analysis. Pooled data based on retrospective cohort studies showed there are more hepatocellular carcinoma patients with vascular invasion (OR 1.74; 95% Cl 1.42, 2.12; P < 0.001) and microvascular invasion (OR 1.62 95% Cl 1.39, 1.89; P < 0.001) in the high NLR group than in the low NLR group. Of case-control studies, a higher preoperative NLR level was found in the microvascular invasion positive group than in the microvascular invasion negative group (OR 0.62; 95% Cl 0.35, 0.90; P < 0.001). The subgroup, sensitivity, and publication bias analyses did not change the results.

CONCLUSION

A higher preoperative NLR level is positively correlated with the risk of microvascular invasion in hepatocellular carcinoma.

Low Preoperative Lymphocyte to Monocyte Ratio Serves as a Worse Prognostic Marker in Patients with Esophageal Squamous Cell Carcinoma Undergoing Curative Tumor Resection

Preoperative lymphocyte to monocyte ratio (LMR) has been considered a prognostic factor in various cancers. However, the application of LMR in the assessment of patients with esophageal squamous cell carcinoma (ESCC) remains controversial. This study aimed to investigate whether preoperative LMR could serve as a prognostic marker in patients with ESCC undergoing curative tumor resection. Medical records of 680 patients of ESCC after curative surgery without preoperative adjuvant therapy were obtained. The median of LMR was determined as the optimal cut off value. The association of LMR with clinical features of ESCC was analyzed using chi-square tests. Spearman's correlation coefficient was used to calculate the correlation. Disease-free survival (DFS) and overall survival (OS) stratified by LMR were evaluated using Kaplan-Meier method and log-rank test. The LMR was negatively correlated with sex (r=-0.245, P<0.001). Low LMR (LMR<3.17) predicted a shorter DFS and OS in patients with ESCC. Multivariate analyses revealed that LMR was independently correlated with DFS (hazard ratios 0.854; 95% confidence interval 0.768-0.949; P=0.003) and OS (hazard ratios 0.864; 95% confidence interval 0.779-0.958; P=0.006). Our study indicated that low LMR could serve as an independent worse prognostic marker in patients with ESCC.

Prognostic significance of inflammatory biomarkers in hepatocellular carcinoma following hepatic resection

Background

Cancer‐related inflammation has been correlated with cancer prognosis. This study evaluated inflammatory biomarkers, including neutrophil‐to‐lymphocyte ratio (NLR), platelet‐to‐lymphocyte ratio (PLR) and lymphocyte‐to‐monocyte ratio (LMR), programmed death ligand (PD‐L) 1 expression, and tumour microenvironment in relation to prognosis and clinicopathological features of patients with hepatocellular carcinoma (HCC) undergoing curative hepatic resection.

Methods

Patients who had liver resection for HCC in 2000–2011 were analysed. Univariable and multivariable analyses were conducted for overall (OS) and recurrence‐free (RFS) survival. Immunohistochemical analyses of PD‐L1, CD8 and CD68 expression were performed. HCC cell lines were evaluated for PD‐L1 expression. A subgroup analysis was conducted to determine patient features, survival and the tumour microenvironment. Results were validated in a cohort of patients with HCC treated surgically in 2012–2016.

Results

Some 281 patients who underwent hepatic resection for HCC were included. Multivariable analysis showed that low LMR was an independent prognostic factor of OS (hazard ratio (HR) 1·59, 95 per cent c.i. 1·00 to 2·41; P = 0·045) and RFS (HR 1·47, 1·05 to 2·04; P = 0·022) after resection. Low preoperative LMR values were correlated with higher α‐fetoprotein values (P < 0·001), larger tumour size (P < 0·001), and high rates of poor differentiation (P = 0·035) and liver cirrhosis (P = 0·008). LMR was significantly lower in PD‐L1‐positive patients than in those with PD‐L1 negativity (P < 0·001). Results were confirmed in the validation cohort. PD‐L1 expression was upregulated in HCC cell lines treated with interferon‐γ and co‐cultured with THP‐1 monocyte cells.

Conclusion

LMR is an independent predictor of survival after hepatic resection in patients with HCC. Modulation of the immune checkpoint pathway in the tumour microenvironment is associated with a low LMR.

Serosal invasion is a strong prognostic factor for hepatocellular carcinoma after hepatectomy

AIM

The clinical impact of serosal invasion by hepatocellular carcinoma (HCC) remains unclear. This study aimed to clarify the significance of serosal invasion as a prognostic factor for patients who underwent hepatectomy for HCC.

METHODS

This retrospective study investigated patients who underwent hepatectomy for HCC between October 2003 and September 2016 in Ehime University Hospital (Toon, Japan). A total of 161 cases were enrolled after excluding cases of concomitant distant metastasis, macroscopic tumor remnant, mixed HCC, and rehepatectomy. We classified these 161 patients into groups with serosal invasion detected (S[+]) and serosal invasion undetected (S[-]). We compared patient characteristics, perioperative data, pathological findings, and prognosis between S(+) and S(-) groups.

RESULTS

Serosal invasion was observed in 19 of the 161 patients (12%). The 5-year recurrence-free survival rate was lower for S(+) (13.0%) than for S(-) (28.7%, P = 0.006). The 5-year overall survival (OS) rate was lower for S(+) (24.7%) than for S(-) (63.9%, P < 0.001). Regarding OS, serosal invasion, preoperative α-fetoprotein value, presence of invasion to hepatic veins, and liver cirrhosis were independent predictors in multivariate analyses. The 3-year OS rate after recurrence was poorer in the S(+) group (22.9%) than in the S(-) group (49.7%, P = 0.001).

CONCLUSIONS

Serosal invasion was a strong predictor of worse outcomes after hepatectomy for HCC. Patients showing serosal invasion need close postoperative follow-up or consideration of adjuvant treatment.

The prognostic and predictive value of the combination of the neutrophil-to-lymphocyte ratio and the platelet-to-lymphocyte ratio in patients with hepatocellular carcinoma who receive transarterial chemoembolization therapy

Purpose

This study was designed to evaluate the prognostic value of the combination of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) (neutrophil/platelet-to-lymphocyte ratio [NLR–PLR]) in patients with hepatocellular carcinoma (HCC) who receive transarterial chemoembolization (TACE) therapy.

Patients and methods

Data from 216 patients who were diagnosed with HCC after TACE therapy were retrospectively collected. R software was used to analyze the time-dependent receiver operating characteristic (ROC) curves and to compare the area under the ROC curves (AUROCs).

Results

The long-term survival rates were significantly higher for patients with lower values than those with higher values of NLR, PLR, and NLR–PLR. The mean overall survival decreased gradually with increases in the NLR–PLR score (P<0.0001). The AUROC values of the NLR–PLR score were consistently higher than those of NLR and PLR.

Conclusion

This study showed that the NLR–PLR score might be a useful predictor for patients with HCC who receive TACE therapy.

Systemic inflammation score predicts survival in patients with intrahepatic cholangiocarcinoma undergoing curative resection

Inflammation has a critical role in the development and progression of cancers. We developed a novel systemic inflammation score (SIS) based on lymphocyte, monocyte, and CA19-9 and explored its prognostic value in intrahepatic cholangiocarcinoma (ICC). From January 2005 to December 2011, 322 consecutive ICC patients who underwent curative resection in our center were included in this study, and validated in a retrospective study of 126 patients enrolled from 2012 to 2014. Clinicopathological variables including preoperative serum CA19-9 and LMR were analyzed. The cutoff values of CA19-9 and LMR were determined based on receiver operating characteristics curve analysis in the primary cohort. Kaplan-Meier curves and multivariate Cox-regression analyses were calculated for time to recurrence (TTR) and overall survival (OS). In univariate analysis of all patients, all three inflammatory and tumor marker including NLR ≥ 2.49 (P<0.001), LMR ≤ 4.45 (P=0.002), and CA19-9≥89 (P<0.001) were associated with poor prognoses. When omitting SIS in multivariate analysis, preoperative LMR (P =0.006) and serum CA19-9 (P<0.001) were independent predictors of OS. In addition, elevated CA19-9 (P=0.001), multiple tumors (P<0.001), and lymph node metastasis (P<0.001) were significant predictors of worse recurrence free survival. Moreover, high SIS was significantly associated with aggressive tumor behaviours including large tumor size (P<0.001), multiple tumors (P=0.033), lymphonodus node metastasis (P=0.001), and high TNM stage (P<0.0001). Finally, univariate and multivariate analyses revealed the SIS was an independent predictor for TTR (HR=2.077, 95% CI, 1.365-3.162, P=0.001) and OS (HR=3.133 95% CI, 2.058-4.769, P<0.001). These results were further confirmed in the validation cohort. In conclusions, our findings demonstrate that the SIS as a potentially powerful prognostic biomarker in ICC that predicts poor clinical outcomes and is a promising tool for ICC treatment strategy decisions.

Lymphocyte-to-Monocyte Ratio Is a Predictor of Survival After Liver Transplantation for Hepatocellular Carcinoma

Recent studies revealed that systemic inflammation was correlated with poorer prognosis in various cancers. We investigated the prognostic value of the lymphocyte-to-monocyte ratio (LMR) in patients who underwent living donor liver transplantation (LDLT) for hepatocellular carcinoma (HCC). We retrospectively analyzed the records of 216 patients who underwent LDLT for HCC. Patients were divided into high (n = 126) and low (n = 90) LMR groups. Their clinicopathological parameters and survival times were compared. To determine the mechanisms of the change in the LMR, we performed immunohistochemical analyses of CD3 and CD68 expression. A low LMR was significantly associated with a high Model for End-Stage Liver Disease score; a high Child-Pugh score; elevation of alpha-fetoprotein, des-gamma-carboxyprothrombin, and neutrophil-to-lymphocyte ratio; larger tumor size; more tumors; and poorer prognosis. A low LMR was associated with poor prognosis and represented an independent prognostic factor, particularly among patients beyond the Milan criteria. The ratio of CD3-positive to CD68-positive cells was significantly lower in the low-LMR group. In conclusion, our results show that the LMR was an independent predictor of survival of patients with HCC beyond the Milan criteria who underwent LDLT. The LMR reflected the immune status of the tumor microenvironment.

Assessing the outcome of patients with liver cirrhosis during hospital stay: A comparison of lymphocyte/monocyte ratio with MELD and Child-Pugh scores

BACKGROUND/AIMS

Developing an easy and reliable score for evaluating the prognosis of patients with liver cirrhosis has always been challenging for hepatologists. This study aimed to assess the lymphocyte-to-monocyte ratio (LMR) in comparison with the Model for End-Stage Liver Disease (MELD) and Child-Pugh (CP) scores for determining the outcomes in these patients during hospital stay.

MATERIALS AND METHODS

Receiver operator characteristic (ROC) curve was used to assess the efficacy of three parameters (LMR and MELD and CP scores) in determining the outcomes in 182 patients with cirrhosis. The cutoff values were calculated using Youden index, and the area under the curves (AUCs) was also compared. The associations of these scores between the survived and nonsurvived group was studied. The predictors of patient survival were determined using logistic regression analysis.

RESULTS

The mean values for LMR and MELD and CP scores were 6.23, 11.62, and 9.32, respectively. MELD and CP were positively correlated with each other. LMR was negatively correlated to both MELD and CP scores (p=0.04). Pairwise comparison showed that the difference between the AUCs of MELD and LMR was not statistically significant (0.958 vs. 0.807; p > 0.05). With the LMR cutoff value of > 3.31 (sensitivity, 80%; specificity, 74.83%), patients were segregated into low and high LMR groups. MELD and CP scores were significantly higher in the low LMR group than in the high LMR group (p=0.000). Patients in the low LMR group showed decreased survival than those in the high LMR group (p=0.000). The nonsurvived group had lower LMR and higher MELD and CP scores than those of the survived group (p=0.000). Logistic regression model showed MELD (p=0.000), CP score (p=0.010), 1/LMR (p=0.004), alanine aminotransferase (ALT) level (p=0.010), and international normalized ratio (INR; p=0.043) as predictors of outcome of these patients.

CONCLUSION

LMR can be used to determine the outcome of patients during hospital stay, because it is easy to calculate and can be interpreted with efficacy nearly equal to those of MELD and CP scores.

Human leukocyte antigen gene polymorphisms are associated with systemic inflammation in hepatitis B virus-related hepatocellular carcinoma

Background

Systemic inflammation (SI) is associated with tumor progression and overall survival (OS) in patients with hepatocellular carcinoma (HCC). The presence of some single nucleotide polymorphisms (SNPs) in the human leukocyte antigen (HLA) region can influence the prognosis of patients with hepatitis B virus (HBV)-related HCC, although the mechanism remains unknown. This study aimed to analyze the correlations between HLA gene polymorphisms and SI.

Patients and methods

This study included 330 patients with HCC. The clinical parameters were reviewed, and five SNPs, namely rs2647073, rs3997872, rs3077, rs7453920, and rs7768538, were genotyped using the MassARRAY system.

Results

The rs3997872, rs7453920, and rs7768538 genotypes were found to be significantly associated with OS (P<0.05). The rs7453920 genotype was significantly associated with the neutrophil/lymphocyte ratio (NLR; P=0.001), which was used as an SI index with a threshold determined by receiver operating characteristic analysis. An elevated NLR was also an independent predictor of OS according to univariate and multivariate analyses (P<0.001).

Conclusion

Our data show that HLA gene polymorphisms are associated with SI in patients with HBV-related HCC, and the absence of minor allele A (rs7453920) promotes SI and shortens OS.

Lymphocyte-to-monocyte ratio in esophageal squamous cell carcinoma prognosis

INTRODUCTION

Recently, the prognostic value of the lymphocyte-to-monocyte ratio (LMR) has been widely evaluated in multiple malignancies. However, its prognostic value in patients with esophageal squamous cell carcinoma (ESCC) remains controversial. Herein, we perform a meta-analysis to assess the prognostic value of the preoperative LMR in ESCC.

METHODS

Relevant studies were systematically retrieved from the online Cochrane, MEDLINE, and EMBASE databases published until March 2018. Data from studies reporting a hazard ratio (HR) and 95% confidence interval (CI) were weighted by generic inverse-variance and pooled in either fixed-effects models or random effects meta-analysis. Seven eligible studies involving 1701 patients were analyzed in this meta-analysis.

RESULTS

The synthesized analysis showed that patients with low LMR had a significantly shorter overall survival (OS) (HR: 0.67, 95% CI: 0.58-0.78, p < 0.001) and disease-free survival (DFS)/progression-free survival (PFS) (HR: 0.67, 95% CI: 0.50-0.92, p = 0.01). Additionally, low LMR was correlated with TNM stage (III-IV vs. I-II; HR = 1.94, 95% CI: 1.16-3.22, P = 0.01) and tumor recurrence (yes vs. no; HR = 1.71, 95% CI: 1.06-2.77, P = 0.03).

CONCLUSION

Low LMR was associated with advanced clinicopathological features and poor prognosis as a predicative biomarker in patients with ESCC.

The prognostic significance of preoperative neutrophil-lymphocyte ratio in patients with hepatocellular carcinoma receiving hepatectomy: A systematic review and meta-analysis

BACKGROUND AND AIMS

Numerous reports have indicated that preoperative Neutrophil-Lymphocyte ratio (NLR) was correlated with the prognosis of hepatocellular carcinoma who underwent hepatectomy. However, the results still remained controversial. Therefore, the present meta-analysis of 17 studies was performed to evaluate the prognostic value of preoperative NLR in HCC patients.

METHOD

Databases of PubMed, Embase, Cochrane Library and Web of Science were retrieved. Hazard Ratio (HR) or Odds Ratio (OR) with its 95% confidence intervals (CI) was used to evaluate the association between preoperative NLR and the prognosis or clinical features of HCC patients.

RESULT

A total of 17 studies eventually were included in this meta-analysis. Elevated preoperative NLR had a close relationship with the overall survival (OS) (HR 1.52; 95% CI 1.37-1.69), recurrence-free survival (RFS) (HR 1.64; 95% CI 1.44-1.87) and disease-free survival (DFS) (HR 1.50; 95% CI 1.35-1.67) of hepatocellular carcinoma. Additionally, preoperative NLR was also associated with tumor vascular invasion (OR 2.08; 95% CI 1.60-2.70), HBV (OR 0.68; 95% CI 0.51-0.90) and large tumor size (OR: 4.07; 95% CI 2.60-6.37).

CONCLUSION

The present meta-analysis indicated that preoperative NLR had significant association with the prognosis of hepatocellular carcinoma patients and may be an effectively prognostic indicator.

Predictive value of the preoperative neutrophil-to-lymphocyte ratio for the development of hepatocellular carcinoma in HBV-associated cirrhotic patients after splenectomy

The neutrophil to lymphocyte ratio (NLR), a simple marker of inflammation, has recently been showed to predict tumor recurrence in hepatocellular carcinoma (HCC) patients after hepatic resection or liver transplantation. However, whether it can be used to predict HCC development in cirrhotic patients remained unknown. The aim of this study was to evaluate the predictive value of the preoperative NLR for the development of HCC in cirrhotic patients who underwent splenectomy. A total of 230 HBV-associated cirrhotic patients who underwent splenectomy in our hospital from January 2000 to December 2012 were included in this study. Detailed clinical data included patients’ general characteristics, laboratory tests and imaging studies, surgical procedures and complications. Information on patients’ follow-up data was also obtained. We found that 38 (16.52%) patients developed HCC after splenectomy during the follow-up period. An elevated preoperative NLR was associated with increased risk of developing HCC in cirrhotic patients after splenectomy. The optimal cutoff value of NLR for HCC development was 2.27. In patients who developed HCC during the follow-up period, NLR scores showed no predictive value in overall survival after splenectomy. However, NLR scores appeared to have a much better predictive value in overall survival in patients who did not develop HCC. In conclusion, cirrhotic patients who underwent splenectomy remain at a relatively high risk of developing HCC, and an elevated preoperative NLR is associated with HCC development in cirrhotic patients who underwent splenectomy for hypersplenism.

The lymphocyte-to-monocyte ratio is a superior predictor of overall survival compared to established biomarkers in HCC patients undergoing liver resection

The aim of this study was to investigate the prognostic value of the lymphocyte-to-monocyte ratio (LMR) in patients undergoing hepatectomy and to compare it to established biomarkers including the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). Medical records were retrospectively analyzed for 652 HCC patients undergoing hepatectomy at the Affiliated Tumor Hospital of Guangxi Medical University and the First People’s Hospital of Changde between April 2004 to April 2012. The correlation between the LMR and clinical variables were analyzed in Kaplan-Meier log-rank survival analysis and then multivariate Cox regression models trying to find relation with disease-free survival (DFS) and overall survival (OS). The area under the ROC curve (AUC) of the LMR(AUC:0.627) for predicting long-term survival was greater than that of the NLR(AUC:0.600) and the PLR(AUC:0.520).Multivariate analysis showed LMR to be an independent risk factor for OS (P = 0.002), and the NLR and PLR were not independently significant. Subgroup analysis also showed that LMR was significantly associated with poor DFS and OS in patients positive for HBsAg or with cirrhosis (both P < 0.001).Elevated preoperative LMR is an independently associated with poor OS and DFS in HCC patients following curative resection and appears to be superior to NLR and PLR.

The pretreatment neutrophil-lymphocyte ratio may predict prognosis of patients with liver cancer: A systematic review and meta-analysis

BACKGROUND

At present, several studies have reported that the pretreatment neutrophil-lymphocyte ratio (NLR) may be associated with the prognosis of liver cancer. Nevertheless, their conclusions remain controversial. Thus, we performed a meta-analysis of 54 studies to evaluate the prognostic value of NLR.

METHOD

Databases including PubMed, Embase, Cochrane Library, and Web of Science were searched to July 2017.

RESULT

A total of 54 studies including 12 979 patients were included in this meta-analysis. Elevated NLR had a close relationship with the overall survival (OS) (HR 1.52; 95% CI 1.39-1.67), recurrence-free survival (RFS) (HR 1.84; 95% CI 1.48-2.30), and disease-free survival (DFS) (HR 1.71; 95% CI 1.39-2.11) of liver cancer, respectively. In addition, elevated NLR was associated with the presence of tumor vascular invasion (OR 2.35; 95% CI 1.93-2.86), multiple tumors (OR 1.38; 95% CI 1.15-1.66), alpha-fetoprotein ≥ 400 ng/mL (OR 1.51; 95% CI 1.15-1.98), presence of HbsAg (+) (OR 0.68; 95% CI 0.51-0.90), and cirrhosis (OR: 0.59; 95% CI 0.44-0.80).

CONCLUSION

This meta-analysis indicated that elevated NLR may be an effective and noninvasive indicator for prognosis of patients with liver cancer.

The pretreatment lymphocyte to monocyte ratio predicts clinical outcome for patients with hepatocellular carcinoma: A meta-analysis

The lymphocyte-to-monocyte ratio (LMR) has been reported to predict clinical outcomes in multiple malignancies. The aim of this study was to assess the prognostic role of pretreatment LMR in hepatocellular carcinoma (HCC). A total of seven studies comprising 2,738 patients were included in the meta-analysis. Pooled results showed that elevated LMR was significantly associated with increased overall survival (OS) (HR: 0.31, 95% CI: 0.20–0.47, p < 0.001), disease-free survival (DFS)/recurrence-free survival (RFS) (HR: 0.57, 95% CI: 0.49–0.67, p < 0.001). The favorable prognostic impact of high LMR on OS was observed in all subgroup with different sample size, type of publication, NOS score, and the cut-off value of LMR. In addition, low LMR was significantly correlated with TNM stage and BCLC stage. We therefore conclude that elevated pretreatment LMR could be a favorable prognostic factor for clinical outcomes in patients with HCC.
