Lymphocyte to monocyte ratio and prognostic nutritional index predict survival outcomes of hepatitis B virus-associated hepatocellular carcinoma patients after curative hepatectomy

Perioperative outcomes after hepatectomy for hepatocellular carcinoma among patients with cirrhosis, fatty liver disease, and clinically normal livers

INTRODUCTION

Despite superior outcomes with liver transplantation, cirrhotic patients with HCC may turn to other forms of definitive treatment. To understand perioperative outcomes, we examined perioperative mortality and major morbidity after hepatectomy for HCC among cirrhotic and non-cirrhotic patients.

METHOD

ology: The American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP) database was queried for liver resection for HCC. Multivariable logistic regression was performed to determine the association between liver texture and risk of major non-infectious morbidity, post-hepatectomy liver failure (PHLF) and 30-day mortality.

RESULTS

From 2014 to 2018, 2203 patients underwent hepatectomy: 58.6 % cirrhotic, 12.8 % fatty and 28.6 % normal texture. Overall 30 day-mortality was 2.1 % (n = 46), although higher among fatty liver (2.8 %) and cirrhotic (2.6 %; p = 0.025) patients. The incidence of PHLF was 6.9 %, with hepatectomy type, cirrhosis, and platelet count as major risk factors. Age, resection type, and platelet count were associated with major complications. Trisegmentectomy and right hepatectomy (OR = 3.60, OR = 3.46, respectively) conferred a greater risk of major noninfectious morbidity compared to partial hepatectomy. Among cirrhotics alone, hepatectomy type, platelet count, preoperative sepsis and ASA class were associated with major morbidity.

DISCUSSION

Hepatic parenchymal disease/texture and function, presence of portal hypertension, and the extent of the liver resection are critical determinants of perioperative risk among HCC patients.

Decoding the Prognostic Significance and Therapeutic Implications of Inflammation-Based Scores in Hepatocellular Carcinoma: A Comprehensive Review

Hepatocellular carcinoma (HCC) is the most common primary liver cancer, posing a significant global health challenge with an increasing incidence. In recent years, multiple staging systems and scores have been proposed, emphasising the necessity for the development of precise prognostic tools. The well-documented etiological relationship between chronic inflammation and carcinogenesis has prompted researchers to explore novel prognostic markers associated with the inflammatory status of HCC patients. This review summarises the current data about inflammation-based scores in the context of HCC. We discuss established scores like the Glasgow Prognostic Score (GPS), modified GPS (mGPS) and the neutrophil-to-lymphocyte ratio (NLR) and others not as extensively studied, examining their utility in predicting survival outcomes and treatment response in HCC patients. Furthermore, we explore emerging scores, including the prognostic nutritional index (PNI) and other lymphocyte-based scores, assessing their potential in refining risk stratification and guiding therapeutic decisions in the era of precision medicine. As research progresses and these scores undergo further refinement and integration into the evolving landscape of HCC management, they carry significant potential for improving patient outcomes.

Conventional and machine learning-based risk scores for patients with early-stage hepatocellular carcinoma

BACKGROUND/AIMS

The performance of machine learning (ML) in predicting the outcomes of patients with hepatocellular carcinoma (HCC) remains uncertain. We aimed to develop risk scores using conventional methods and ML to categorize early-stage HCC patients into distinct prognostic groups.

METHODS

The study retrospectively enrolled 1,411 consecutive treatment-naïve patients with the Barcelona Clinic Liver Cancer (BCLC) stage 0 to A HCC from 2012 to 2021. The patients were randomly divided into a training cohort (n=988) and validation cohort (n=423). Two risk scores (CATS-IF and CATS-INF) were developed to predict overall survival (OS) in the training cohort using the conventional methods (Cox proportional hazards model) and ML-based methods (LASSO Cox regression), respectively. They were then validated and compared in the validation cohort.

RESULTS

In the training cohort, factors for the CATS-IF score were selected by the conventional method, including age, curative treatment, single large HCC, serum creatinine and alpha-fetoprotein levels, fibrosis-4 score, lymphocyte-tomonocyte ratio, and albumin-bilirubin grade. The CATS-INF score, determined by ML-based methods, included the above factors and two additional ones (aspartate aminotransferase and prognostic nutritional index). In the validation cohort, both CATS-IF score and CATS-INF score outperformed other modern prognostic scores in predicting OS, with the CATSINF score having the lowest Akaike information criterion value. A calibration plot exhibited good correlation between predicted and observed outcomes for both scores.

CONCLUSION

Both the conventional Cox-based CATS-IF score and ML-based CATS-INF score effectively stratified patients with early-stage HCC into distinct prognostic groups, with the CATS-INF score showing slightly superior performance.

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

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

Comparing Long-Term survival benefits of hepatocellular carcinoma between thermal ablation monotherapy and combined therapy with transarterial Chemoembolization: A propensity score matched study

PURPOSE

To compare the long-term survival benefits of hepatocellular carcinoma (HCC) in thermal ablation (TA) monotherapy and TA combined with transarterial chemoembolization (TACE) using propensity score matching (PSM).

MATERIALS AND METHODS

Between 1 January 2015 and 28 February 2021, 432 consecutive patients (357 men, 75 women; age range, 20-87 years) with HCC (Barcelona Clinic Liver Cancer stage 0-B) underwent ultrasonography-guided percutaneous TA, which included radiofrequency ablation (n = 340) and microwave ablation (n = 92). The association between combined treatment of TACE prior to TA versus TA monotherapy and survival prognosis was evaluated, including (a) local tumor progression (LTP) by using a logistic regression model, and (b) disease-free survival (DFS) and (c) overall survival (OS) by using a Cox proportional hazards model according to propensity score matched data.

RESULTS

After PSM, the final matched cohort consisted of 146 patients, with 73 receiving TA monotherapy and 73 receiving TA combined with TACE. The cumulative LTP rates did not show a significant difference between the two groups (P = 0.960). Neither the DFS nor OS rate was significantly different between the two groups (P = 0.070 and P = 0.680, respectively). The multivariate analysis identified two significant findings. Firstly, ultrasound echo, minimal ablative margin, and high risk of tumor burden score were found to be associated with LTP. Secondly, the type of TA, Child-Turcotte-Pugh grade, ablation time, and lymphocyte-monocyte ratio were identified as independent prognostic factors for OS.

CONCLUSION

The differences in LTP, DFS, and OS rates of HCC patients were found to be statistically non-significant between TA monotherapy and TACE + TA groups. For HCC patients with BCLC stage 0-B, the combination treatment of TACE prior to TA may be not associated with long-term survival benefits relative to TA monotherapy.

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.

Lymphocyte-to-Monocyte Ratio and Clinical Outcomes in Cholangiocarcinoma: A Systematic Review and Meta-Analysis

Lymphocyte-to-Monocyte ratio (LMR) has shown an association with survival outcomes in several oncological diseases. This study aimed to evaluate the association between LMR and clinical outcomes for cholangiocarcinoma patients. A systematic review and meta-analysis were performed to assess the association between LMR values and overall survival (OS), disease-free survival (DFS), recurrence-free survival (RFS) and time to recurrence (TTR) in cholangiocarcinoma patients. We used Hazard ratio (HR) and their 95% confidence interval (CI) as a measure of effect for the random effect model meta-analysis. The Newcastle-Ottawa Scale was used for quality assessment. The Egger test and funnel plot were developed for approaching publication bias. A total of 19 studies were included in this study (n = 3860). The meta-analysis showed that cholangiocarcinoma patients with low values of LMR were associated with worse OS (HR: 0.82; 95% CI: 0.71-0.96; I2 = 86%) and worse TTR (HR: 0.71; 95% CI: 0.58-0.86; I2 = 0%). DFS and RFS also were evaluated; however, they did not show statistically significant associations. Low LMR values were associated with a worse OS and TTR.

Relationship of Immunonutritional factor with Changes in Liver Volume after Portal Vein Embolization

Background

To identify predictors of changes in hepatic volumes after portal vein embolization, we examined the relationship with preoperative nutritional and immunological parameters.

Patients and Methods

Ninety-three patients who underwent portal vein embolization were included. The control group comprised 13 patients who underwent right hepatectomy without portal vein embolization. Computed tomographic volumetric parameter was measured for changes in embolized and nonembolized liver. Correlation with various candidates of immunonutritional parameters was examined.

Results

Difference in increased liver ratio was 9.1%. C-reactive protein levels significantly increased after portal vein embolization (P < .01), whereas albumin and total cholesterol levels significantly decreased, respectively (P < .01). The C-reactive protein/albumin ratio, prognostic nutritional index, Controlling Nutritional Status score, and modified Glasgow Prognostic Score were significantly different, respectively (P < .01). Prothrombin activity and total cholesterol level significantly correlated with the increased change in nonembolized liver (P < .05). The C-reactive protein and C-reactive protein/albumin ratio after portal vein embolization negatively correlated with hypertrophic ratio (P < .05). By comparing posthepatectomy outcomes between 64 patients undergoing portal vein embolization and 13 who did not, the prevalence of severe complications and mortality in the portal vein embolization group was not different from that in the non–portal vein embolization group. Liver activity at 15 minutes > 0.92 and increased liver volume ≥ 10% tended to correlate with lower prevalence of severe complications. Only increased intraoperative blood loss ≥ 1,500 mL was significantly associated with morbidity and mortality (P < .05).

Conclusion

Contrary to our hypothesis, immunonutritional parameters, except C-reactive protein and C-reactive protein/albumin ratio, did not reflect hypertrophy after portal vein embolization. Although it is difficult to predict the hypertrophic degree, the strategy of scheduled hepatectomy should be switched in case of impaired inflammatory status after portal vein embolization.

Development of nomogram models of inflammatory markers based on clinical database to predict prognosis for hepatocellular carcinoma after surgical resection

BACKGROUND

Inflammation plays a significant role in tumour development, progression, and metastasis. In this study, we focused on comparing the predictive potential of inflammatory markers for overall survival (OS), recurrence-free survival (RFS), and 1- and 2-year RFS in hepatocellular carcinoma (HCC) patients.

METHODS

A total of 360 HCC patients were included in this study. A LASSO regression analysis model was used for data dimensionality reduction and element selection. Univariate and multivariate Cox regression analyses were performed to identify the independent risk factors for HCC prognosis. Nomogram prediction models were established and decision curve analysis (DCA) was conducted to determine the clinical utility of the nomogram model.

RESULTS

Multivariate Cox regression analysis indicated that the prognostic nutritional index (PNI) and neutrophil-to-lymphocyte ratio (NLR) were independent prognostic factors of OS, and aspartate aminotransferase-to-platelet ratio (APRI) was a common independent prognostic factor among RFS, 1-year RFS, and 2-year RFS. The systemic inflammation response index (SIRI) was an independent prognostic factor for 1-year RFS in HCC patients after curative resection. Nomograms established and achieved a better concordance index of 0.772(95% CI: 0.730-0.814), 0.774(95% CI: 0.734-0.815), 0.809(95% CI: 0.766-0.852), and 0.756(95% CI: 0.696-0.816) in predicting OS, RFS, 1-year RFS, and 2-year RFS respectively. The risk scores calculated by nomogram models divided HCC patients into high-, moderate- and low-risk groups (P < 0.05). DCA analysis revealed that the nomogram models could augment net benefits and exhibited a wider range of threshold probabilities in the prediction of HCC prognosis.

CONCLUSIONS

The nomograms showed high predictive accuracy for OS, RFS, 1-year RFS, and 2-year RFS in HCC patients after surgical resection. The nomograms could be useful clinical tools to guide a rational and personalized treatment approach and prognosis judgement.

A nomogram for predicting the risk of postoperative recurrence of hepatitis B virus-related hepatocellular carcinoma in patients with high preoperative serum glutamyl transpeptidase

BACKGROUND

Recurrence is a major risk factor affecting the postoperative survival of patients with hepatocellular carcinoma (HCC), especially those with high preoperative serum γ-glutamyl transpeptidase (GGT) levels. This study had the aim of developing a personalized predictive tool to accurately determine the risk of postoperative recurrence of hepatitis B-virus (HBV)-related HCC in patients with high preoperative serum GGT levels.

METHODS

Patients who underwent curative liver resection of HBV-related HCC and had high preoperative GGT levels were consecutively enrolled between 2008 and 2011. Prognostic indicators for recurrence were determined using Cox regression analysis. A nomogram was then developed and assessed by integrating the independent risk factors into the model.

RESULTS

A total of 603 eligible patients were included. The final nomogram for predicting HCC recurrence in patients with high preoperative GGT levels consisted of five independent prognostic factors: α-fetoprotein (AFP), HBV-DNA, satellite nodules, microvascular invasion, and tumor grade. The C-index of the nomogram for predicting recurrence was 0.759, and validation showed high accuracy and discriminatory.

CONCLUSIONS

The predictive nomogram developed and validated in this study performs well in predicting postoperative recurrence of HBV-related HCC in patients with high preoperative GGT levels. It can provide personalized assessments to inform the development of surveillance strategies and allows patients with a high risk of recurrence to be selected for further adjuvant treatment.

Efficacy of Ninjin'yoeito in treating severe coronavirus disease 2019 in patients in an intensive care unit

Coronavirus Disease-2019 (COVID-19), an infectious disease associated with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), is a global emergency with high mortality. There are few effective treatments, and many severe patients are treated in an intensive care unit (ICU). The purpose of this study was to evaluate whether the Japanese Kampo medicine ninjin'yoeito (NYT) is effective in treating ICU patients with COVID-19. Nine patients with confirmed SARS-CoV-2 infection admitted to the ICU were enrolled in this study. All patients underwent respiratory management with invasive mechanical ventilation (IMV) and enteral nutrition. Four patients received NYT (7.5 g daily) from an elemental diet tube. We retrospectively examined the prognostic nutritional index (PNI), length of IMV, length of ICU stay, length of hospital stay, rate of tracheostomy, and mortality rate. The median age of the enrolled participants was 60.0 years (4 men and 5 women). The median body mass index was 27.6. The most common comorbidity was diabetes (4 patients, 44%), followed by hypertension (3 patients, 33%) and chronic kidney disease (2 patients, 22%). The median length of IMV, ICU stay, and hospital stay were all shorter in the NYT group than in the non-NYT group (IMV; 4.0 days vs 14.3 days, ICU; 5.3 days vs 14.5 days, hospital stay; 19.9 days vs 28.2 days). In the NYT and non-NYT groups, the median PNI at admission was 29.0 and 31.2, respectively. One week after admission, the PNI was 30.7 in the NYT group and 24.4 in non-NYT group. PNI was significantly (p = 0.032) increased in the NYT group (+13.6%) than in the non-NYT group (-22.0%). The Japanese Kampo medicine NYT might be useful for treating patients with severe COVID-19 in ICU. This study was conducted in a small number of cases, and further large clinical trials are necessary.

Impact of prognostic nutritional index on the recurrence of hepatocellular carcinoma after a curative resection

Backgrounds/Aims

The purpose of this retrospective study was to determine the association between prognostic nutritional index (PNI) and recurrence of hepatocellular carcinoma after a curative resection.

Methods

Between 2007 to 2019, 130 patients who underwent curative hepatectomy for hepatocellular carcinoma were enrolled. PNI was calculated. Its cutoff value was identified through receiver operating characteristic curve analysis. According to PNI, patients were divided into two groups. Univariate and multivariate analyses were performed to identify independent risk factors for recurrence.

Results

The cutoff value of PNI was 52. In univariate analysis, alcoholic liver cirrhosis (p = 0.041), protein induced by vitamin K antagonist- II &ge; 200 (p = 0.012), indocyanine green retention test (ICG R15) >10% (p = 0.001), estimated blood loss &ge; 800 mL (p = 0.037), tumor size (p = 0.001), microvascular invasion (p = 0.023), T-stage (p = 0.001), and PNI < 52 (p = 0.001) were significant factors affecting the recurrence. In multivariate analysis, alcoholic liver cirrhosis (p = 0.046), ICG R15 >10% (p = 0.025), T-stage (p = 0.003), and PNI < 52 (p = 0.046) were independent prognostic factors for disease-free survival.

Conclusions

PNI, a nutritional and immunologic factor, is an independent prognostic factor that can predict the recurrence of hepatocellular carcinoma in patients undergoing a curative resection.

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.

Combining Preoperative and Postoperative Inflammatory Indicators Can Better Predict the Recurrence of Hepatocellular Carcinoma After Partial Hepatectomy

Purpose

Previous studies have shown that various preoperative inflammatory indicators can predict the prognosis of hepatocellular carcinoma (HCC), but the role of postoperative inflammatory indicators remains unclear. This study aimed to explore the prognostic value of postoperative inflammatory indicators and whether combining preoperative and postoperative inflammatory indicators can improve the predictive performance of the prognostic model.

Patients and Methods

Eighty-eight patients with primary HCC were included in this study. A preoperative model, postoperative model, and combined model that integrated preoperative and postoperative inflammatory indicators were established. The prognostic value of the models was evaluated by the area under the curve of time-dependent receiver operating characteristic curves (td-AUC).

Results

Multivariate analysis of preoperative and postoperative inflammatory indicators and clinicopathological indicators found that tumor number, alpha-fetoprotein (AFP) level, and the preoperative platelet-lymphocyte ratio (prePLR), preoperative prognostic nutritional index (prePNI), and postoperative neutrophil-lymphocyte ratio (postNLR) were independent prognostic factors for the disease-free survival. The prognostic efficacy of the postNLR at 2 years and 3 years was better than that of tumor number, AFP level, and the prePLR, and prePNI. The combined model had higher td-AUC values than the preoperative model, postoperative model, American Joint Committee on Cancer 8th edition stage, and Barcelona Clinic Liver Cancer stage at 2 years (0.814 vs 0.754, 0.765, 0.513 and 0.527, respectively), and 3 years (0.786 vs 0.749, 0.753, 0.509 and 0.529, respectively). The predictive performance of the combined model was better than that of the preoperative model, postoperative model, and traditional clinical stage.

Conclusion

Postoperative inflammatory indicators were valuable prognostic indicators. The combination of preoperative and postoperative inflammatory indicators improved the predictive performance of the prognostic model. We should pay more attention to postoperative inflammatory indicators.

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.

Meta-analysis of the prognostic value of pretreatment serum ferritin in hepatobiliary and pancreas (HBP) cancers

BACKGROUND AND OBJECTIVES

Studies have shown that serum ferritin (SF) has unfavourable prognostic value in hepatobiliary and pancreas (HBP) cancers. This meta-analysis aimed to comprehensively assess the prognostic role of pretreatment SF in patients with HBP cancers.

METHODS

Eligible studies published before January 2020 were obtained through a comprehensive search in the PubMed, Web of Science, Cochrane Library and EMBASE databases. Pooled HRs and 95% CIs were then employed as effect sizes.

RESULTS

Seven studies comprising 1244 patients were pooled. Elevated pretreatment SF was associated with worse overall survival (OS) (HR 1.60, 95% CI 1.36 to 1.88, p<0.001) and recurrence-free survival/progression-free survival/time to recurrence (HR 1.70, 95% CI 1.15 to 2.52, p=0.008). Significant prognostic value of elevated pretreatment SF on OS was detected in the subgroups regardless of the cancer type, race, SF cut-off value, tumour-node-metastasis stage and Newcastle-Ottawa Scale score.

CONCLUSION

Elevated pretreatment SF was associated with worse survival outcome of patients with HBP cancers. As such, it may serve as a novel prognostic biomarker for HBP cancers.

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.

The Prognostic Nutritional Index is associated with mortality of COVID-19 patients in Wuhan, China

BACKGROUND

Declared as pandemic by WHO, the coronavirus disease 2019 (COVID-19) pneumonia has brought great damage to human health. The uncontrollable spread and poor progression of COVID-19 have attracted much attention from all over the world. We designed this study to develop a prognostic nomogram incorporating Prognostic nutritional index (PNI) in COVID-19 patients.

METHODS

Patients confirmed with COVID-19 and treated in Renmin Hospital of Wuhan University from January to February 2020 were included in this study. We used logistic regression analysis to find risk factors of mortality in these patients. A prognostic nomogram was constructed and receiver operating characteristics (ROC) curve was drawn to evaluate the predictive value of PNI and this prognostic model.

RESULTS

Comparison of baseline characteristics showed non-survivors had higher age (P < .001), male ratio (P = .038), neutrophil-to-lymphocyte ratio (NLR) (P < .001), platelet-to-lymphocyte ratio (PLR) (P < .001), and PNI (P < .001) than survivors. In the multivariate logistic regression analysis, independent risk factors of mortality in COVID-19 patients included white blood cell (WBC) (OR 1.285, P = .039), PNI (OR 0.790, P = .029), LDH (OR 1.011, P < .015). These three factors were combined to build the prognostic model. Area under the ROC curve (AUC) of only PNI and the prognostic model was 0.849 (95%Cl 0.811-0.888) and 0.950 (95%Cl 0.922-0.978), respectively. And calibration plot showed good stability of the prognostic model.

CONCLUSION

This research indicates PNI is independently associated with the mortality of COVID-19 patients. Prognostic model incorporating PNI is beneficial for clinicians to evaluate progression and strengthen monitoring for COVID-19 patients.

Preoperative controlling nutritional status (CONUT) score predicts long-term outcomes in patients with non-B non-C hepatocellular carcinoma after curative hepatic resection

PURPOSE

The controlling nutritional status (CONUT) score has been reported to predict outcomes in patients with hepatocellular carcinoma (HCC). However, the prognostic significance of the CONUT score in patients with non-B non-C (NBNC) HCC remains to be established.

METHODS

The study comprised 246 patients who had undergone elective hepatic resection for HCC between April 2003 and October 2017. We retrospectively investigated the relation between preoperative CONUT score as well as clinicopathological characteristics and disease-free survival (DFS) as well as overall survival (OS).

RESULTS

In univariate analyses, CONUT score was associated with DFS and OS in patients with NBNC-HCC (p ≤ 0.01), while there was no significant association of CONUT score with DFS and OS in patients with HBV- and HCV-related HCC (p ≥ 0.1). Of the 111 patients with NBNC-HCC, 97 (87.4%) had CONUT score ≤ 3 (low CONUT score) and the other 14 (12.6%) had CONUT score ≥ 4 (high CONUT score). In the patients with NBNC-HCC, multivariate analysis identified age ≥ 65 years (p = 0.03), multiple tumors (p < 0.01), and high CONUT score (p = 0.03) as the independent and significant predictors of DFS, while multiple tumors (p = 0.01), microvascular invasion (p < 0.01), and high CONUT score (p = 0.01) were the independent and significant predictors of OS.

CONCLUSIONS

The CONUT score seems to be a reliable and independent predictor of both DFS and OS after hepatic resection for NBNC-HCC.

Lymphocyte to monocyte ratio-based nomogram for predicting outcomes of hepatocellular carcinoma treated with sorafenib

BACKGROUND

The ability of the pretreatment lymphocyte to monocyte ratio (LMR) to predict outcomes of patients with hepatocellular carcinoma (HCC) receiving sorafenib is not conclusively determined.

METHODS

We retrospectively studied patients treated with sorafenib for HCC in two tertiary referral centres in Asia and North America. Primary endpoints were overall survival (OS) and progression-free survival (PFS). Predictive factors for the outcomes were determined by Cox proportional hazards models. A risk assessment tool was developed.

RESULTS

Compared to the North America cohort, the Asia cohort was more heavily pretreated (72.1% vs. 35.2%; p < 0.001), had higher hepatitis B virus infection (87.6% vs. 5.6%; p < 0.001), and more distant metastases (83.2% vs. 25.4%; p < 0.001). Lower monocyte count in the Asia cohort (median 462.7 vs. 600.0/μL; p = 0.023) resulted in a higher LMR (median 2.6 vs. 1.8; p < 0.001). High LMR was associated with a significantly higher OS [hazard ratio (HR) 0.88; 95% confidence interval (CI) 0.81‒0.97; p = 0.007]. This was confirmed in a sensitivity analysis including patients treated in Asia only (HR 0.89; 95% CI 0.81‒0.97; p = 0.010). An OS nomogram was constructed with the following variables selected in the multivariate Cox model: LMR, treatment location, previous treatment, performance status, alpha-fetoprotein, lymph node metastasis, and Child‒Pugh score. The concordance score was 0.71 (95% CI, 0.67‒0.75). LMR did not predict PFS.

CONCLUSION

LMR measured before sorafenib administration predicts OS in advanced HCC patients. Our OS nomogram, incorporating LMR, can be offered to clinicians to improve their ability to assess prognosis, strengthen the prognosis-based decision-making, and inform patients in the clinic.

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.

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

Objectives:

To investigate the prognostic value of neutrophil-to-lymphocyte ratio (NLR) plus the lymphocyte-to-monocyte ratio (LMR) to predict survival outcomes in huge hepatocellular carcinoma (HCC) patients undergoing transarterial chemoembolization (TACE).

Methods:

There were 180 huge HCC patients undergoing TACE between 2011 and 2017 were retrospectively analyzed. Patients who has an increased NLR (>3.94) and a decreased LMR (≤2.20) were assessed score 2 according to receiver operating characteristic (ROC) curve, and patients who were assigned with 1, with one of these characteristic or 0 with neither of these characteristics. We used univariate and multivariate analyses for evaluations of the predicative NLR, LMR and other values about overall survival (OS) using multivariate Cox’s regression.

Results:

The liver function index such as aspartate transaminase, alanine transaminase, and total bilirubin, as well as inflammatory biomarkers like absolute neutrophil count, monocyte count, lymphocyte count, seemed much larger than the groups with an NLR-LMR score of 2 than in the other 2 groups (p<0.05 for all), including BCLC stage. Higher NLR plus a low level of LMR predicted a short median OS. Multivariate Cox’s regression revealed that an NLR-LMR score of 2 was a useful predictor of OS in huge HCC patients after TACE.

Conclusion:

The pretreatment NLR plus LMR are effective for predicting survival outcomes in huge HCC patients after TACE.

Prognostic value of pre-treatment Naples prognostic score (NPS) in patients with osteosarcoma

BACKGROUND

This study aimed to evaluate the clinical significance of pre-treatment Naples prognostic score (NPS) in patients with osteosarcoma.

METHODS

The clinical data of 133 osteosarcoma patients between January 2011 and February 2018 in our hospital was retrospectively collected and analyzed. NPS was calculated from four parameters, including serum albumin level, serum total cholesterol (TC), lymphocyte-to-monocyte ratio (LMR), and neutrophil-to-lymphocyte ratio (NLR). Patients were divided into three groups (group 1-3) based on NPS. The relationships between NPS and clinical features, overall survival (OS), and progression-free survival (PFS) were analyzed. Two prediction models based on NPS and clinical parameters were developed: clinical parameters model (model A), and the combined model of NPS and clinical parameters (model B). Their predictive performances were further evaluated and compared.

RESULTS

The median follow-up time of this cohort was 46.0 (range, 5-75) months, while the median OS and PFS was 40 (range, 5-75) months and 36 (range, 5-71) months, respectively. NPS was significantly correlated with gender, tumor location, Enneking stage, pathological fracture, local recurrence, and metastasis (all P < 0.05). Variables of NPS, Enneking stage, local recurrence, metastasis, and NLR were confirmed as independent prognostic factors for OS and PFS by univariate and multivariate Cox analysis. Prediction model B obtained larger AUCs for OS and PFS and showed better consistency between nomogram-predicted and actual survival than that of model A at the follow-up time of 1-, 3-, and 5-year.

CONCLUSIONS

NPS was a novel, reliable, and multidimensional prognostic scoring system with favorable predictive performance for patients with osteosarcoma.

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.

Comparative performance of inflammation-based prognostic scores in patients operated for intrahepatic cholangiocarcinoma

Objective

Prognostic performance of inflammation-based prognostic scores, including the Glasgow Prognostic Score (GPS), modified Glasgow Prognostic Score (mGPS), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), Prognostic Index (PI) and Prognostic Nutritional Index (PNI) has been explored in patients with varied types of cancer, though little data is available in intrahepatic cholangiocarcinoma (ICC). This study sought to evaluate the impact of systemic inflammation on the overall survival (OS) of ICC patients, and to identify more optimal prognostic indices.

Patients and methods

The prognostic power of all the scores mentioned above was compared in 123 patients underwent curative surgery for ICC using Kaplan–Meier curves, COX regression models and the receiver operating characteristics (ROC) curves. The results were validated in a cohort of 95 ICC patients.

Results

Multivariate analysis identified LMR as the only independent inflammation-based predictor for OS in the training cohort (P=0.007, HR 2.082, 95% CI 1.218–3.558). More importantly, the combined score of LMR and pTNM designated the inflammation-based pathological stage (IPS) outperformed other established scores in terms of discriminatory ability, monotonicity and homogeneity in the training and validation cohorts.

Conclusion

This study reveals that preoperative LMR is an independent predictor of OS in ICC patients after hepatectomy, and the IPS can be applied as a novel prognostic indicator in these patients.

Haematologic indices in hepatitis B virus-related liver disease

Several markers and prognostic scores have been identified for predicting the development and progression of liver disease; among them, haematological parameters (the neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), platelet to lymphocyte ratio (PLR), red cell distribution width (RDW), RDW to platelet ratio (RPR), mean platelet volume (MPV), and mean corpuscular volume (MCV)) have recently gained significant interest. Compared with traditional prognostic factors, haematological indices are easy to obtain and relatively inexpensive. There is growing evidence that these haematological indices play a key role in HBV-related liver diseases and has been proposed as a predictive marker of adverse outcomes in these patients. This article focuses on discussing the diagnostic and prognostic value of the haematological indices in patients with HBV-related liver diseases.

Prognostic Nutritional Index and Neutrophil-to-Lymphocyte Ratio Are Respectively Associated with Prognosis of Gastric Cancer with Liver Metatasis Undergoing and without Hepatectomy

Background. To clarify the efficacy of hepatectomy for gastric cancer liver metastasis (GCLM) and to investigate the association between prognostic nutrition index (PNI) or neutrophil-to-lymphocyte ratio (NLR) and prognosis of GCLM undergoing or without hepatectomy. Methods. We retrospectively studied 374 patients with GCLM. The ROC curve was used to determine the optimal cut-off of PNI and NLR. Patients were divided into groups based on whether hepatectomy was performed, and survival analysis was conducted before and after grouping. The overall survival (OS) time and 1, 3, 5-year survival rates were also compared. Results. Multivariate analysis of all GCLM patients revealed that hepatectomy (p = 0.001) was an independent prognosis factor. And there were statistical differences in OS and 1, 3, 5-year survival rates (p = 0.001 of all) between hepatectomy group and nonhepatectomy group. Multivariate analysis of GCLM undergoing hepatectomy showed that PNI was an independent prognosis factor (p = 0.001). And there were statistical differences in OS and 1, 3, 5‐year survival rates (p = 0.001p = 0.005, p = 0.001 and p = 0.020, respectively) between high PNI group and low PNI group. Multivariate analysis of GCLM without hepatectomy showed that NLR was an independent prognosis factor (p = 0.001). And there were statistical differences in OS and 1, 3, 5-year survival rates (p = 0.001p = 0.008p = 0.031 and p = 0.026, respectively) between low NLR group and high NLR group. Conclusions. GCLM has a better prognosis with hepatectomy. High preoperative PNI is a benign prognostic predictor for patients undergoing hepatectomy. And high preoperative NLR is an adverse prognostic factor for patients without hepatectomy.

Prognostic significance of preoperative albumin-to-globulin ratio and prognostic nutritional index combined score in Siewert type 3 adenocarcinoma of esophagogastric junction

Purpose

Preoperative nutrition-inflammation-based indicators have been reported to predict the prognosis of malignancies. We evaluated the prognostic significance of a combined score of the albumin-to-globulin ratio (AGR) and prognostic nutritional index (PNI) for overall survival (OS) outcomes in patients with Siewert type 3 adenocarcinoma of esophagogastric junction (S3-AEG).

Patients and methods

The prognostic significance of variables associated with 215 S3-AEG patients’ OS were assessed through univariate and multivariate analyses. The cutoff value of the preoperative AGR and PNI were calculated by the receiver operating characteristic curve (ROC). Patients with either an elevated AGR (≥1.72, cutoff value) or PNI (≥45.55, cutoff value) were given a score of 1; otherwise, they were given a score of 0. The AGR-PNI score ranged from 0 to 2.

Results

OS was independently associated with the N stage (HR: 0.336, 95% CI: 0.141–0.805, P=0.014) and AGR-PNI score (HR: 0.623, 95% CI: 0.487–0.797, P<0.001). Patients with AGR-PNI scores of 0, 1 and 2 had significant differences in OS (P=0.001). The prognostic role of AGR-PNI was significant in patients with stage I + II (P=0.043) and stage III S3-AEGs (P=0.003). ROC analysis indicated that the predictive ability of the AGR-PNI score was better than that of the other parameters.

Conclusion

The preoperative AGR-PNI score was a significant prognosticator of postoperative survival in patients with S3-AEG and could identify high-risk populations for reasonable therapy and effective follow-up.

Controlling nutritional status (CONUT) score-based nomogram to predict overall survival of patients with HBV-associated hepatocellular carcinoma after curative hepatectomy

PURPOSE

As a novel immune-nutritional biomarker, the controlling nutritional status (CONUT) score has been reported to predict outcomes in cancer patients. We aimed to elucidate the prognostic value of preoperative CONUT score and construct a CONUT score-based nomogram to predict individual survival of patients with hepatitis B viral (HBV)-associated hepatocellular carcinoma (HCC) after curative hepatectomy.

METHODS

Preoperative CONUT score was retrospectively calculated in 380 HBV-associated HCC patients undergoing radical resection between 2006 and 2012. Patients were assigned to two groups: CONUT-low ( < 2) and CONUT-high ( ≥ 2), according to the optimal cut-off value determined using receiver operating characteristic analysis. Associations of CONUT score with oncological outcomes were evaluated. The Cox proportional hazard model was used to identify predictors of survival and a new nomogram was developed based on the independent prognostic factors for overall survival (OS).

RESULTS

The CONUT score exhibited a higher area under the curve value than the other immune-nutritional parameters. The CONUT-high group had significant poorer OS and recurrence-free survival compared with CONUT-low group (P < 0.001 and P = 0.016, respectively). Multivariate analyses identified CONUT score, liver cirrhosis, tumor size and differentiation as independent prognostic factors for OS. And the nomogram based on these four variables had superior discriminative ability to predict survival compared with other conventional staging systems.

CONCLUSIONS

Preoperative CONUT score is an effective independent predictor of OS in patients with resected HBV-related HCC. This novel nomogram based on CONUT may provide accurate and individualized survival prediction for HCC patients undergoing surgical resection.

Preoperative lymphocyte-to-monocyte ratio is useful for stratifying the prognosis of hepatocellular carcinoma patients with a low Cancer of the Liver Italian Program score undergoing curative resection

BACKGROUND AND AIM

Although the Cancer of the Liver Italian Program (CLIP) score is useful for prognostication of patients with hepatocellular carcinoma (HCC), a previous study has reported that the CLIP score was unable to stratify the postoperative outcomes of HCC patients in whom the score was low (0-1). Recent studies have reported that the preoperative lymphocyte-to-monocyte ratio (LMR) is useful for prognostication of patients with various cancer.

METHODS

We reviewed 329 HCC patients with a low CLIP score (0-1) undergoing curative resection. This study had the approval of the Institutional Review Board (28068). Multivariate analyses were carried out to detect clinical factors correlating with overall survival (OS). Kaplan-Meier analysis and the log-rank test were used for comparison of OS.

RESULTS

Multivariate analysis showed that LMR (<4.35/≥4.35) was significantly associated with OS (hazard ratio [HR], 2.022; 95% CI, 1.141-3.583; P = 0.016) as well as portal vein invasion (HR, 2.410; 95%CI, 1.258-4.618; P = 0.008). Kaplan-Meier analysis and the log-rank test showed a significant difference in OS and relapse-free survival between patients with high LMR and those with low LMR.

CONCLUSION

Preoperative LMR is useful for stratifying the prognosis of HCC patients with a low CLIP score (0-1) undergoing curative resection.

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.

Hepatic resection of solitary HCC in the elderly: A unique disease in a growing population

BACKGROUND

Management of elderly patients with solitary hepatocellular carcinoma (sHCC) is challenging with perceived clinicopathologic differences driving treatment options. We sought to determine factors predictive of disease control and survival after hepatic resection of sHCC in elderly patients.

METHODS

We identified n = 45 elderly patients (³≥65 yo) with sHCC treated with hepatic resection alone from our prospective database from 2003-16. Clinicopathologic data were analyzed and survival was assessed from the time of hepatic resection.

RESULTS

The median age was 75-years-old. Less than half of patients (47%) had viral hepatitis. At resection, the median Child-Pugh score was A6, median tumor size 5 cm, and mean AFP of 1050 (ng/mL). Major hepatectomy was performed in 23 patients (51%) with R0 resection achieved in 96%. Two patients (4%) had Grade III complications with no mortalities at 30 days and one death (2%) at 90-days. After R0 resection 44% (n = 20) had intrahepatic recurrence at a median of 32 months (95% CI: 15-46) with 20% (n = 9) developing extrahepatic recurrence at a median of 78 months (95% CI: 78-.). The median survival was 72 months (95% CI: 30-108 months). For patients with at least 3 years of follow-up, the 1-, 3-, and 5-year overall survival was 74%, 59%, and 50%, respectively. Mortality was associated with higher AFP and lower Prognostic Nutritional Index (PNI).

CONCLUSION

Carefully selected elderly patients with sHCC appear to have unique disease that is amenable to hepatic resection with low morbidity and mortality with excellent overall and recurrence-free survival.

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.

Nomograms based on inflammatory biomarkers for predicting tumor grade and micro-vascular invasion in stage I/II hepatocellular carcinoma

Background: Increasing evidences reveal that inflammation plays a critical role in tumorigenesis and progression. We aimed to develop the nomograms based on inflammatory biomarkers to predict micro-vascular invasion (MVI) and tumor grade in stage I/II hepatocellular carcinoma (HCC).Methods: A retrospective cohort of 627 patients with stage I/II HCC between January 2007 and December 2014 was included in the study. Logistic regression was performed to identify the independent risk factors of tumor grade and MVI. The significant predictors including neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), lymphocyte-to-monocyte ratio (LMR), tumor volume age, and tumor size were subsequently incorporated to build the nomograms. The prediction accuracies of the nomograms were evaluated using the area under the receiver operating characteristic (ROC) curve.Results: The independent risk factors for tumor grade were NLR, dNLR, and tumor volume (P<0.001, P=0.001, and P<0.001, respectively), which were assembled into tumor grade nomogram. MVI nomogram was developed by dNLR, LMR, age, and tumor size (P<0.001, P<0.001, P<0.001, and P=0.001, respectively) which were the independent predictors for MVI. The area under the ROC curve of nomograms for predicting tumor grade and MVI were 0.727 (95% confidence intervals [CI]: 0.690-0.761) and 0.839 (95% CI: 0.808-0.867), respectively. Patients who had a nomogram score of less than 100 and 79 were considered to have high possibility of moderate grade and have low risks of MVI presence, respectively.Conclusion: We successfully developed nomograms predicting tumor grade and MVI based on inflammatory biomarkers with high accuracy, leading to a rational therapeutic choice for stage I/II HCC.

Prognostic value of inflammation-based indexes for intrahepatic cholangiocarcinoma following curative resection

It is widely acknowledged that inflammatory indices may serve as effective prognosis indicators for various malignancies. In the present study, the prognostic value of systemic inflammatory biomarkers for patients undergoing curative resection for intrahepatic cholangiocellular carcinoma (ICC) was investigated. Clinical data of ICC patients who underwent curative resection between September 2008 and July 2017 were collected. Inflammatory indictors were analyzed using the Area Under the Receiver Operating Characteristic Curve. Indictors that were significantly associated with the overall survival (OS) were used to establish a systemic inflammation-based score system and tested via nomogram using R software. The neutrophil To lymphocyte ratio (NLR) and lymphocyte to macrophages ratio (LMR) were significantly associated with the OS and disease-free survival of the patients. High NLR and low LMR were associated with worse clinicopathological and survival outcomes. The univariate and multivariate analyses indicated that tumor T stage, incisal margin, NLR and LMR were associated with the OS of the patients. The systemic inflammation-based scoring system based on LMR and NLR demonstrated a stronger discriminatory capacity and may serve as a useful prognostic parameter for patients undergoing curative resection for ICC. Low LMR and high NLR were observed to be associated with poor prognosis and worse clinical outcomes for patients with ICC undergoing curative surgery. A combined inflammation-based scoring system based on LMR and NLR may effectively predict the outcomes and serve as a novel prognostic predictor for these patients.

The prognostic value of prognostic nutritional index in hepatocellular carcinoma patients: A meta-analysis of observational studies

Background and aims

The clinical value of the prognostic nutritional index (PNI) in hepatocellular carcinoma (HCC) has been investigated in previous studies, but the results remain controversial. Here we present a meta-analysis to systematically review the association between PNI and HCC prognosis.

Method

PubMed, EMBASE, Web of Science databases were systematically searched to identify relevant studies. Data were abstracted independently by two reviewers. A meta-analysis was performed to determine the prognostic and clinic-pathological values of PNI in HCC patients. Odds ratios (ORs) and 95% confidence intervals (CIs) were extracted to estimate the association of PNI with survival and clinic-pathological characteristics, respectively.

Results

A total of eleven studies involving 3165 patients were analyzed. The pooled results indicated that low PNI is a significant predictor of poor 1-year, 3-year, 5-year OS (OR, 2.91, 4.05, 3.65; 95%CI, 2.30 to 3.70, 3.27 to 5.03,2.96–4.50; P = 0.14,0.22,0.11 respectively) and disease-free survival (DFS) (OR,2.35, 2.57, 2.75; 95%CI, 1.71 to 3.23, 1.89 to 3.49,2.01 to 3.75; P = 0.39,0.04,0.11, respectively). Moreover, PNI is significantly associated with serum AFP, tumor recurrence, tumor size and TNM stages in HCC patients. However, PNI is not significantly associated with tumor number and the incidence of cirrhosis in HCC patients.

Conclusions

PNI is an independent predictive indicator of survival and associated with serum AFP, tumor recurrence, tumor size and TNM stages in HCC patients.

Role of monocyte-to-lymphocyte ratio in predicting sorafenib response in patients with advanced hepatocellular carcinoma

Purpose

Sorafenib is the first-line treatment for patients with unresectable hepatocellular carcinoma (HCC), and its clinical response rate is only about 10%. In clinical practice, some HCC patients obtain favorable overall survival (OS) to the treatment of sorafenib while some patients do not demonstrate a sensitive response to sorafenib. Therefore, it is valuable to determine the subgroups of patients who respond well as well as poorly to sorafenib. Thus, clinical variables of advanced HCC patients with sorafenib treatment were compiled to investigate whether monocyte-to-lymphocyte ratio (MLR) could be a biomarker for predicting sorafenib response.

Patients and methods

In this study, a total of 142 patients with advanced HCC were enrolled from January 1, 2013 to December 31, 2016 at the Fudan University Shanghai Cancer Center. MLR was analyzed using a ROC curve. A Cox regression model and log-rank test were performed to analyze the relationship between clinical factors and OS, as well as progression free survival (PFS).

Results

The optimal cut-off point for MLR was 0.35, and MLR level had no significant correlation with age, gender, hepatitis B infection, grade, alpha-fetoprotein (AFP) level and state of portal vein tumor thrombus. Multivariate Cox regression model showed that grade (HR: 0.608, 95% CI: 0.409–0.904, P=0.014), AFP (HR: 0.445, 95% CI: 0.307–0.645, P=0.0001), MLR (HR: 0.445, 95% CI: 0.301–0.658, P=0.0001) and aspartate aminotransferase (AST) (HR: 1.005, 95% CI: 1.001–1.009, P=0.007) may serve as independent prognostic predictors for OS, and MLR maintained significant correlation with PFS in HCC patients (HR: 0.457, 95% CI: 0.308–0.678, P=0.0001). By log-rank test, there was longer PFS and OS in patients with low MLR than in those with high MLR (both P=0.0001).

Conclusion

MLR can predict sorafenib response and a high MLR is correlated with poor prognosis in patients with advanced 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.

A new laboratory-based algorithm to predict microvascular invasion and survival in patients with hepatocellular carcinoma

BACKGROUND

Preoperative serum inflammatory markers have been correlated with survival outcomes after resection of hepatocellular carcinoma (HCC). Whether they can predict microvascular invasion (MVI) in HCC is still unknown. This study aimed to evaluate the association of inflammatory markers with MVI, and develop a simple and inexpensive preoperative prediction model for MVI.

METHODS

We developed a novel index using routine laboratory tests to predict MVI. The index was developed based on a study on patients with HCC, and validated in an internal cohort and another external cohort. The infiltration of CD8⁺ T cells in tumors was measured using immunohistochemistry. The prediction accuracy was evaluated with the area under the receiver operating characteristic curve (AUC).

RESULTS

There were 165 patients in the training cohort, 107 patients in the internal validation cohort and 80 patients in the external validation cohort. On multivariable analysis in the training cohort, alkaline phosphatase (ALP) and lymphocyte count were independent predictors of MVI. Thus, the ALP-to-lymphocyte ratio (ALR) was developed. The AUCs of the ALR for MVI were higher than the other conventional clinical indices. An optimal cutoff point for the ALR of 69.9 stratified HCC patients into the high (≥69.9) and low (<69.9) groups. An ALR ≥69.9 was significantly associated with worse overall and disease-free survival outcomes. The performance of ALR was validated in the internal and in external cohorts. The CD8⁺ T cell counts were significantly higher in HCC in the ALR<69.9 groups.

CONCLUSION

ALR was a simple, accurate and inexpensive alternative to predict MVI and an independent risk factor of prognosis for HCC patients. The dismal survival outcomes in patients with high ALR scores were related to decreased infiltrations of CD8⁺ T cells in tumors.

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.

Clinicopathological and prognostic significance of platelet-to-lymphocyte ratio in patients with hepatocellular carcinoma

The platelet-to-lymphocyte ratio (PLR) is reported to be a prognostic factor in multiple malignancies. The aim of this study was to assess its prognostic value in hepatocellular carcinoma (HCC). We performed comprehensive searches of electronic databases for relevant studies. A total of eleven studies comprising 2,507 patients were included. Elevated PLR was significantly associated with poor overall survival (OS) (HR = 1.78; 95% CI = 1.36-2.34; P < 0.001) and disease-free survival (DFS)/recurrence-free survival (RFS) (HR = 1.82; 95% CI = 1.56-2.13; P < 0.001). The findings from most subgroup analyses were consistent with those from the overall analysis. In addition, a high PLR correlated with tumor size > 3 cm, TNM stage, lymph node metastasis, distant metastasis, and vascular invasion. We therefore conclude that elevated pretreatment PLR may be predicative of a poor prognosis in patients with HCC.

Naples Prognostic Score, Based on Nutritional and Inflammatory Status, is an Independent Predictor of Long-term Outcome in Patients Undergoing Surgery for Colorectal Cancer

BACKGROUND

The existing scores reflecting the patient's nutritional and inflammatory status do not include all biomarkers and have been poorly studied in colorectal cancers.

OBJECTIVE

The purpose of this study was to assess a new prognostic tool, the Naples prognostic score, comparing it with the prognostic nutritional index, controlling nutritional status score, and systemic inflammation score.

DESIGN

This was an analysis of patients undergoing surgery for colorectal cancer.

SETTINGS

The study was conducted at a university hospital.

PATIENTS

A total of 562 patients who underwent surgery for colorectal cancer in July 2004 through June 2014 and 468 patients undergoing potentially curative surgery were included. MaxStat analysis dichotomized neutrophil:lymphocyte ratio, lymphocyte:monocyte ratio, prognostic nutritional index, and the controlling nutritional status score. The Naples prognostic scores were divided into 3 groups (group 0, 1, and 2). The receiver operating characteristic curve for censored survival data compared the prognostic performance of the scoring systems.

MAIN OUTCOME MEASURES

Overall survival and complication rates in all patients, as well as recurrence and disease-free survival rates in radically resected patients, were measured.

RESULTS

The Naples prognostic score correlated positively with the other scoring systems (p < 0.001) and worsened with advanced tumor stages (p < 0.001). Patients with the worst Naples prognostic score experienced more postoperative complications (all patients, p = 0.010; radically resected patients, p = 0.026). Compared with group 0, patients in groups 1 and 2 had worse overall (group 1, HR = 2.90; group 2, HR = 8.01; p < 0.001) and disease-free survival rates (group 1, HR = 2.57; group 2, HR = 6.95; p < 0.001). Only the Naples prognostic score was an independent significant predictor of overall (HR = 2.0; p = 0.03) and disease-free survival rates (HR = 2.6; p = 0.01). The receiver operating characteristic curve analysis showed that the Naples prognostic score had the best prognostic performance and discriminatory power for overall (p = 0.02) and disease-free survival (p = 0.04).

LIMITATIONS

This is a single-center study, and its validity needs additional external validation.

CONCLUSIONS

The Naples prognostic score is a simple tool strongly associated with long-term outcome in patients undergoing surgery for colorectal cancer. See Video Abstract at http://links.lww.com/DCR/A469.

Utility of Serum Inflammatory Markers for Predicting Microvascular Invasion and Survival for Patients with Hepatocellular Carcinoma

BACKGROUND

Preoperative serum inflammatory markers have been correlated with outcome after resection of hepatocellular carcinoma (HCC), but studies have had conflicting results. This study aimed to evaluate the association of six inflammatory markers with recurrence-free survival (RFS), overall survival (OS), and microvascular invasion (MVI), a well-known prognostic factor.

METHODS

This study investigated 370 patients who underwent resection of HCC from 1992 to 2016, retrospectively evaluating their inflammatory indices and individual components including their neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), prognostic nutritional index (PNI), aspartate aminotransferase-to-platelet ratio index (APRI), and aspartate aminotransferase-to-neutrophil ratio index (ANRI). Uni- and multivariate analyses were performed to evaluate these markers for RFS, OS, and MVI.

RESULTS

The median RFS was 23 months, and the median OS was 60 months. Factors independently associated with worse RFS were higher PLR and alpha-fetoprotein level, male gender, and the presence of MVI as well as multiple nodules. Factors independently associated with worse OS were higher PLR and international normalized ratio, male gender, older age, presence of MVI and multiple nodules, larger tumor, presence of cirrhosis, and absence of steatosis. The study identified MVI in 47% of the patients. Lower level of albumin, higher level of alpha-fetoprotein, and larger tumor on preoperative imaging were independently associated with MVI.

CONCLUSIONS

This largest Western series to evaluate the utility of preoperative inflammatory markers in patients with HCC found that only PLR was associated with RFS and OS and that albumin was associated with MVI.

The prognostic value of inflammation-based scores in advanced hepatocellular carcinoma patients prior to treatment with sorafenib

Background and Aims

The multikinase inhibitor sorafenib is the only currently approved drug for the indication of advanced hepatocellular carcinoma (HCC). It provides a limited gain in survival time but is frequently associated with adverse events. We currently lack simple prognostic factors in sorafenib-treated HCC patients. Various inflammation-based scores (IBSs) have been evaluated as predictors of tumor recurrence and survival in various malignancies (including HCC). The objective of the present study was to determine the prognostic value of IBSs for overall survival (OS) in advanced HCC patients prior to the initiation of sorafenib therapy.

Methods

Patients with Barcelona Clinic Liver Cancer stage C HCC were enrolled retrospectively between October 2007 and September 2015. To identify prognostic factors for OS, bivariate and multivariate analysis were performed using a Cox proportional hazards regression model.

Results

161 patients (87.0% males; median age: 67; median OS: 9.1 months) were enrolled. A multivariate analysis identified a body mass index <25kg/m² (hazard ratio (HR)=1.55, p<0.017), macroscopic vascular invasion (HR=1.63, p< 0.001), an AST level >38 U/L (HR=2.65, p<0.001), Child Pugh B stage (HR=2.59, p<0.001) and a systemic immune-inflammation index (SII) ≥600 × 10⁹ (HR 1.72, p=0.002) as independent risk factors for OS in advanced HCC.

Conclusion

IBSs (such as the SII) are novel, simple, low-cost prognostic indices in patients with advanced HCC. They may be of value in determining whether these patients may benefit from sorafenib therapy.

Preoperative prognostic nutritional index is a powerful predictor of prognosis in patients with stage III ovarian cancer

Many established inflammation- and nutrition-related factors have been investigated as potential independent prognostic factors in various cancers, including the C-reactive protein/albumin ratio (CAR), lymphocyte/monocyte ratio (LMR), modified Glasgow prognostic score (mGPS), body mass index (BMI), and prognostic nutritional index (PNI). This study was performed to estimate the prognostic value of these factors in predicting survival and platinum resistance in ovarian cancer (OC), especially according to stage. Kaplan-Meier and multivariate analyses were performed to plot the survival curve and determine the independent prognostic factors. Additionally, the area under the receiver operating characteristic curve (AUC) was used to predict platinum resistance and prognosis by comparing the predictive ability of PNI and cancer antigen (CA)-125. In all patients, decreased PNI was significantly associated with platinum resistance and poor overall survival (OS) and progression-free survival (PFS). Regarding tumor stage, decreased PNI was significantly associated with poor PFS and OS only in stage III OC. Furthermore, the PNI also showed a significantly higher AUC value than CA-125 for predicting mortality and platinum resistance in all OC patients, but not in stage III patients. In conclusion, decreased PNI is a powerful predictor of a poor prognosis in OC, and especially for stage III cases.

Preoperative platelet-to-lymphocyte ratio is a valuable prognostic biomarker in patients with hepatocellular carcinoma undergoing curative liver resection

The Platelet to lymphocyte ratio (PLR) has been reported to predict prognosis of patients with hepatocellular carcinoma (HCC). This study examined the prognostic potential of stratified PLR for HCC patients undergoing curative liver resection. Medical records were retrospectively analyzed for 778 HCC patients undergoing curative liver resection at the Affiliated Tumor Hospital of Guangxi Medical University and the First People's Hospital of Changde between April 2010 and October 2013. Patients were stratified based on quintile analysis of their preoperative PLR, and patients in different quintiles were analyzed for overall survival (OS) and disease-free survival (DFS) using Kaplan-Meier analysis. Independent predictors of death or recurrence were explored using multivariable Cox proportional hazard regression. Higher PLR quintiles were significantly associated with poorer overall survival (p < 0.001). Multivariate analysis showed PLR to be an independent risk factor for OS (p = 0.003). Patients in PLR quintile 5 had lower overall survival than in quintile 1 (hazard ratio (HR) = 2.780, 95% confidence interval (CI): 1.769-4.367, p < 0.001). Although patients in PLR quintile 5 had significantly lower disease-free survival (DFS) than in quintile 1 (HR = 1.534, 95% CI: 1.112-2.117, p = 0.009), this association was not significant after multivariable adjustment (p = 0.220). Subgroup analysis also showed that PLR quintiles were significantly associated with poor OS in patients positive for HBsAg or with cirrhosis (both p < 0.001). Similar results were obtained when PLR was analyzed as a dichotomous variable with cut-off values of 110 and 115. Elevated preoperative PLR may be independently associated with poor OS and DFS in HCC patients following curative resection.

Clinical Significance of Prognostic Nutritional Index After Surgical Treatment in Lung Cancer

BACKGROUND

The prognostic nutritional index (PNI), calculated as 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (cells/mm³), can reportedly predict postoperative complications and prognosis for various types of malignancy. However, the clinical significance and prognostic value of the PNI for both short- and long-term outcomes remains uncertain in patients with lung cancer.

METHODS

We retrospectively reviewed 248 patients with completely resected non-small cell lung cancer (NSCLC). Clinicopathologic characteristics were evaluated according to the PNI, and the prognostic significance for postoperative outcomes was assessed using Cox proportional regression analysis. The survival rate was calculated using the Kaplan-Meier method.

RESULTS

An optimal cutoff of 48 for recurrence-free survival (RFS) was determined using the minimum p value approach. Old age, low body mass index, large tumor size, and elevated C-reactive protein levels correlated significantly with low PNI. Logistic regression analysis demonstrated that low PNI status was statistically related to postoperative complications (Clavien-Dindo grade ≥II) and pulmonary air leakage. Five-year overall survival (OR) rates in the high- and low-PNI groups were 80.6% and 58.5%, respectively (p = 0.002). Five-year RFS rates were 73.6% and 48.6%, respectively (p < 0.001). Furthermore, PNI was identified as an independent prognostic factor for OS (hazard ratio [HR], 2.18; 95% confidence interval [CI], 1.08-4.21) and RFS (HR, 2.57; 95% CI, 1.46-4.38) by multivariate analysis.

CONCLUSIONS

The PNI could represent a useful biomarker to predict postoperative complications and survival in patients with completely resected NSCLC.

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.

Actual 10-Year Survivors After Resection of Hepatocellular Carcinoma

BACKGROUND

Resection of hepatocellular carcinoma (HCC) offers a chance of cure, but recurrence is common and survival is often limited. The clinical and pathological characteristics of long-term survivors have not been well studied.

METHODS

We retrospectively reviewed 212 patients who underwent partial hepatectomy for HCC with curative intent from 1992 to 2006. Fifty patients who survived beyond 10 years were compared with 109 patients who died of recurrence within 10 years.

RESULTS

Multivariate analysis showed that tumors <5 cm (odds ratio [OR] 2.3, p = 0.04), solitary tumors (OR 3.2, p = 0.01), and absence of vascular invasion (OR 2.3, p = 0.04) were independently associated with actual 10-year survival. However, more than 20% of long-term survivors also possessed established poor prognostic factors, including α-fetoprotein >1000 ng/mL, unfavorable serum inflammatory indices, tumor size >10 cm, microvascular invasion, poor tumor differentiation, cirrhosis, and metabolic syndrome. None of the 10-year survivors had an R1 resection. While 77% of the short-term survivors developed recurrence within 2 years, 42% of the 10-year survivors developed recurrence during their decade of follow-up, although most of the recurrences among 10-year survivors were intrahepatic and amenable to further treatment. Among patients who survived beyond 10 years, 42% remained alive without recurrence.

CONCLUSIONS

In this largest Western series of actual 10-year survivors after HCC resection, almost one in four patients survived over a decade, even though nearly half of this subset had developed recurrence. While many well-known variables were associated with a poor outcome, only a positive microscopic margin precluded long-term survival.

Pretreatment Lymphocyte Monocyte Ratio Predicts Long-Term Outcomes in Patients with Digestive System Tumor: A Meta-Analysis

Purpose. The prognostic value of pretreatment lymphocyte monocyte ratio (LMR) in digestive system cancer patients remains controversial. The aim of this study was to quantify the prognostic impact of this biomarker and assess its consistency in digestive system tumors. Methods. We searched "PubMed," "Embase," and "CBM" for published eligible studies before June 2016 and conducted a meta-analysis to estimate the pooled hazard ratios (HRs) for disease recurrence and mortality focusing on LMR. Subgroup analyses, meta-regression, and sensitivity analyses were also performed. Results. A total of 22 cohort studies enrolling 12829 patients with digestive system cancer were included. The summary results showed that lower LMR was significantly associated with worse overall survival (OS), cancer-specific survival (CSS), and tumor disease or recurrence-free survival (DFS/RFS) in analyses using the studies reporting HRs either by the univariate analyses (HR = 1.32, HR = 1.35, and HR = 1.26 for OS, CSS, and DFS/RFS, resp.) or by multivariate analyses (HR = 1.21, HR = 1.18, and HR = 1.26 for OS, CSS, and DFS/RFS, resp.). Conclusion. Our results support the fact that decreased LMR indicates worse prognosis in multiple digestive system tumors.
