Neutrophil-to-lymphocyte ratio as prognostic marker in esophageal cancer: a systematic review and meta-analysis

Methods for diagnosing malnutrition in patients with esophageal cancer, and the association with nutritional and inflammatory indices: A cross‑sectional study

Clinically, it is important to diagnose malnutrition for the treatment and prognosis of cancer patients; however, at present, there are no established standards. The present study evaluated the consistency of malnutrition diagnostic tools in association with relevant nutritional and inflammatory markers in patients with advanced esophageal cancer. Specifically, the Patient-Generated Subjective Global Assessment (PG-SGA) and Global Leadership Initiative on Malnutrition (GLIM) tools were assessed. Patients with a new diagnosis of esophageal cancer at Tengzhou Central People's Hospital (Tengzhou, China) between January 2023 and December 2023 were evaluated within 24 h of admission using Nutritional Risk Screening 2002 (NRS2002), GLIM and PG-SGA. Additionally, relevant physical examinations and laboratory data were collected. The malnutrition occurrence rates based on PG-SGA, GLIM and GLIM with NRS2002 screening (NRS2002-GLIM) were 75.01, 51.88 and 41.25%, respectively. The agreement between PG-SGA and GLIM, and between PG-SGA and NRS2002-GLIM diagnoses was weak (κ=0.379, P<0.001; and κ=0.376, P<0.001, respectively). PG-SGA showed a moderate negative correlation with body mass index (BMI) (rs=-0.460), weak positive correlations with age (rs=0.234) and IL-6 (rs=0.249), and very weak negative correlations with albumin (rs=-0.178) and PNI (rs=-0.168). While the indicators correlated with GLIM and PG-SGA were consistent, the strength of correlation varied slightly. Logistic regression analysis of PG-SGA and GLIM indicated that age and BMI were independent risk factors for malnutrition. In addition, PG-SGA also showed that the neutrophil count was an independent risk factor for malnutrition. Overall, patients with esophageal cancer exhibit a high incidence of malnutrition, and different diagnostic methods provide varying results. Malnutrition is closely associated with age, inflammatory markers and BMI, suggesting their potential utility in guiding nutritional interventions for patients with esophageal cancer.

Neutrophil-to-Lymphocyte Ratio as a Prognostic Biomarker for Long-Term Survival in Older Adults at a Mental Health Care Center: A Historical Cohort Analysis

Background/Objectives: Identifying reliable biomarkers for healthy aging and longevity is a fundamental challenge in aging research and medical sciences. The neutrophil-to-lymphocyte ratio (NLR) is a readily measurable indicator of immune balance that reflects the interplay between innate immune activation and adaptive immune suppression. Methods: This study examined NLR values in 204 physically healthy residents (98 men and 106 women) stratified into four lifespan categories based on death certificates. Page's test and ordinal regression (Cumulative Link Model) were used to assess trends with longevity. Results: In men, a downward trend in NLR values was observed. In women, a significant age-related decline in NLR was identified, with longer-lived individuals showing notably lower NLR values compared to their shorter-lived counterparts. The findings suggest that lower NLR is associated with longer survival, particularly in older women, reflecting superior immune regulation and reduced systemic inflammation. Conversely, elevated NLR may indicate immune dysfunction and heightened inflammatory burden. Conclusions: The results of this study complement existing findings, reinforcing the critical importance of immune balance in supporting healthy aging and longevity. These findings also underscore the potential of NLR as a robust biomarker for evaluating immune function and anticipating resilience to age-related decline, offering a practical tool for assessing immune health in the aging population.

Integrating tumour and lymph node radiomics features for predicting disease-free survival in locally advanced esophageal squamous cell cancer after neoadjuvant chemotherapy and complete resection

PURPOSE

To investigate the utility of combined tumour and lymph node (LN) radiomics features in predicting disease-free survival (DFS) among patients with locally advanced esophageal squamous cell carcinoma (ESCC) after neoadjuvant chemotherapy and resection.

METHODS

We retrospectively enrolled 176 ESCC patients from January 2013 to December 2016. Tumour and targeted LN segmentation were performed on venous phase CT images. Models were constructed using LASSO Cox regression: a clinical model, a clinical-tumour radiomics model, and a clinical-tumour-LN radiomics model. Model fitting was evaluated using Akaike information criterion and likelihood ratio (LR), while performance was assessed using Harrell's concordance index (C-index) and time-dependent receiver operating characteristic analysis.

RESULTS

The clinical model included clinical stage and neutrophil-to-lymphocyte ratio (NLR). Integration of tumour features significantly improved prognostic accuracy (clinical-tumour model vs. clinical model, LR: 17.84 vs. 11.84, P = 0.049). Subsequent integration of LN features further augmented model performance (clinical-tumour-LN model vs. clinical-tumour model, LR: 24.48 vs. 17.84, P = 0.009). The final model included clinical stage, NLR, two tumour features (Conventional_mean and GLZLM_HGZE), and one LN feature (GLCM_entropy). The C-index was 0.68 for the training set and 0.70 for the test set. The nomogram based on these features effectively stratified patients into high- and low-risk groups (P < 0.001).

CONCLUSIONS

The clinical-tumour-LN model, integrating clinical stage, NLR, and radiomics features, outperformed simpler models in predicting DFS among ESCC patients after neoadjuvant chemotherapy and resection. This underscores the potential of radiomics data to enhance prognostic models, offering clinicians a more robust tool for assessment.

Inflammatory Biomarkers from Blood Counts as Prognostic Tools in Metastatic Esophageal Cancer

BACKGROUND Globally, esophageal cancer ranks as the sixth leading cause of cancer-related mortality. This retrospective study from a single center in Turkey aimed to evaluate hematological inflammatory biomarkers in complete blood count (CBC) data and outcomes in 113 patients with advanced esophageal carcinomas. MATERIAL AND METHODS We conducted a retrospective analysis of 113 patients with metastatic esophageal cancer composed of squamous (92), adenocarcinoma (18), and small cell (3) histology. We investigated neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte ratio (PLR), neutrophil-to-platelet lymphocyte ratio (NLPR), neutrophile-to-monocyte ratio (NMR), systemic inflammation index (SII), systemic inflammatory response index (SIRI), and aggregate index of systemic inflammation (AISI) in terms of prognosis. RESULTS The initial treatment for 25.7% of patients consisted of a carboplatin-paclitaxel combination. In response to the initial round of chemotherapy, 52.2% of patients showed improvement (15% complete, 37.2% partial), while 18.6% experienced disease progression. Neutropenia was observed as the most prevalent severe (grades 3-4) adverse reaction, affecting 19.8% of patients. Higher NLR, PLR, SII, NLPR, SIRI, and AISI values were associated with worse survival (P=0.016, P=0.008, P=0.011, P=0.028, P=0.014, P=0.001, respectively), whereas higher LMR was correlated with better survival (P=0.001). The NMR analysis showed no significant association (P=0.46). Multivariate analysis identified independent prognostic factors except histology, PLR, and NLPR. CONCLUSIONS Research indicates that inflammatory indicators obtained from complete blood count analyses possess prognostic significance for individuals with metastatic esophageal cancer. These biomarkers demonstrate diverse capacities in forecasting the course of the disease. These simple and inexpensive markers need further confirmation to guide individualized treatment planning.

Biomarkers associated with anastomotic leakage after esophagectomy: a systematic review

PURPOSE

Anastomotic leakage (AL) is one of the most important complications that occurs after upper gastrointestinal surgery, registering rates of 20-30% after esophagectomy. The role of systemic inflammatory biomarkers to predict anastomotic leaks is controversial and needs systematization.

METHODS

A systematic review based on the PRISMA guidelines criteria was performed. PubMed, Scopus, and Embase were queried using MESH Terms and All Fields key words to identify studies investigating a range of immune-inflammatory factors in predicting AL.

RESULTS

Twenty-four studies were included in this review. The total number of included patients was 5903, ranging in each study from 42 to 612. The included studies reported patients that underwent different techniques of esophagectomy (Ivor Lewis, McKeown, Orringer or thoracoabdominal esophagectomy) and 23 out of 24 studies included patients that underwent neoadjuvant treatment. While different biomarkers at different timepoints were analyzed, most studies have indicated postoperative biomarkers, between day 3 and day 5 to reach statistical significance.

CONCLUSIONS

Systemic inflammatory biomarkers represent potential risk stratification and predicting tools for AL after esophageal surgery, but more studies need to be conducted to validate their clinical utility.

A Comparison of Established Diagnostic Criteria for Cachexia and Their Impacts on Prognostication in Patients with Oesophagogastric Cancer

BACKGROUND

Cachexia is common in patients with oesophagogastric cancer. The syndrome is characterised by tissue wasting (muscle and fat), anorexia, and reduced physical function, which result from complex interactions between the tumour and its host. Heterogeneity in the diagnostic criteria used for cachexia has hindered their clinical utilisation. This study aimed to compare the two established cachexia definitions (Fearon's consensus definition and the Global Leadership Initiative on Malnutrition [GLIM] criteria) and their relationships with survival in patients with oesophagogastric cancer.

METHODS

Consecutive patients newly diagnosed with oesophagogastric cancer (January 2019 to December 2020) were identified from a prospective regional database. Involuntary weight loss, BMI, CT body composition analyses, and neutrophil-lymphocyte ratios were recorded at clinical staging. These data were used to assess patients for cachexia according to Fearon and GLIM diagnostic criteria. The primary outcome of interest was overall survival.

RESULTS

Overall, 465 patients (66.9% male, median 71 years) were diagnosed with oesophagogastric cancer during the 2-year study period. Cachectic proportions differed between definitions (Fearon: 59.1% vs. GLIM: 44.1%), and only 49.1% of the 322 patients who met one set of diagnostic criteria were cachectic according to both. Patients who met the GLIM criteria were significantly more comorbid and had a poorer performance status; however, no such difference was evident when using the Fearon definition. Those patients who met either set of diagnostic criteria had shorter survival than those who met neither (p < 0.001). Following adjustment for confounders, GLIM-defined cachexia was more strongly associated with reduced survival (aHR: 1.57 [95% CI: 1.25-1.96], p < 0.001) than Fearon-defined cachexia (aHR: 1.41 [95% CI: 1.13-1.76], p = 0.002). Patients who only met the Fearon diagnostic criteria had prolonged survival (median: 363 days) when compared to those who met only GLIM (median: 158 days) or both definitions (median: 120 days). A secondary analysis of those patients who met the GLIM diagnostic criteria (n = 205) compared the three potential phenotypical criteria used in this definition. Only reduced muscle mass, and not low BMI or weight loss, was associated with poorer survival (aHR: 1.88 [95% CI: 1.15-3.07], p = 0.012) in this group.

CONCLUSIONS

Cancer cachexia is strongly associated with shortened survival in patients with oesophagogastric cancer. Classification using the GLIM criteria provides more effective prognostication and this definition should be utilised in multidisciplinary patient care.

The heterogeneity of neutrophils in cancer and its implication for therapeutic targeting

Neutrophils have a pivotal role in safeguarding the host against pathogens and facilitating tissue remodeling. They possess a large array of tools essential for executing these functions. Neutrophils have a critical role in cancer, where they are largely associated with negative clinical outcome and resistance to therapy. However, the specific role of neutrophils in cancer is complex and controversial, owing to their high functional diversity and acute sensitivity to the microenvironment. In this Perspective, we discuss the accumulated evidence that suggests that the functional diversity of neutrophils can be ascribed to two principal functional states, each with distinct characteristics: classically activated neutrophils and pathologically activated immunosuppressive myeloid-derived suppressor cells. We discuss how the antimicrobial factors in neutrophils can contribute to tumor progression and the fundamental mechanisms that govern the pathologically activated myeloid-derived suppressor cells. These functional states play divergent roles in cancer and thus require separate consideration in therapeutic targeting.

Systematic review and meta-analysis of the association of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio with periodontitis

INTRODUCTION

Recent evidence suggests the relationship between periodontitis and systemic inflammation, which complete blood count can assess (CBC)-derived biomarkers such as neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). We conducted this meta-analysis to evaluate the levels of NLR and PLR of patients with periodontitis compared to those of healthy controls.  METHODS: Web of Science, PubMed, ProQuest, Scopus, and Open Grey were searched for studies published before October 20, 2024, without any limitation on date and language; then, using the random-effects model, we reported a standardized mean difference (SMD) with a 95% confidence interval (CI). In order to assess the quality of publications, we used the Newcastle-Ottawa scale (NOS). Our study was registered in PROSPERO (CRD42023475214).

RESULTS

Overall, 11 articles were included in the analysis. We found that patients with periodontitis had elevated levels of NLR compared to healthy controls (SMD = 0.30, 95% CI 0.08-0.52, p = 0.007) In the subgroup analysis according to race, patients with periodontitis had elevated levels of NLR compared to healthy controls in among East Asian patients (SMD = 0.35, 95% CI 0.15-0.55, p = 0.001), but not among Turkish (SMD = 0.15, 95% CI - 0.30-0.61, p = 0.50) and Indian (SMD = 0.38, 95% CI - 0.17-0.94, p = 0.18) patients. In addition, PLR level was not different among patients with periodontitis and healthy controls (SMD = 0.06, 95% CI - 0.71-0.83, p = 0.87).

CONCLUSIONS

The findings of our investigation, which indicate higher NLR levels in periodontitis patients, show that immune dysregulation plays a role in the etiology of the disease.

Associations between peripheral whole blood cell counts derived indexes and cancer prognosis: An umbrella review of meta-analyses of cohort studies

Meta-analyses have reported conflicting data on the whole blood cell count (WBCC) derived indexes (neutrophil-to-lymphocyte ratio [NLR], platelet-to-lymphocyte ratio [PLR], and lymphocyte-to-monocyte ratio [LMR]) and cancer prognosis. However, the strength and quality of this evidence has not been quantified in aggregate. To grade the evidence from published meta-analyses of cohort studies that investigated the associations between NLR, PLR, and LMR and cancer prognosis. A total of 694 associations from 224 articles were included. And 219 (97.8%) articles rated as moderate-to-high quality according to AMSTAR. There were four associations supported by convincing evidence. Meanwhile, 165 and 164 associations were supported by highly suggestive and suggestive evidence, respectively. In this umbrella review, we summarized the existing evidence on the WBCC-derived indexes and cancer prognosis. Due to the direction of effect sizes is not completely consistent between studies, further research is needed to assess causality and provide firm evidence.

Neutrophils' dual role in cancer: from tumor progression to immunotherapeutic potential

The tumor microenvironment (TME) is intricately associated with cancer progression, characterized by dynamic interactions among various cellular and molecular components that significantly impact the carcinogenic process. Notably, neutrophils play a crucial dual role in regulating this complex environment. These cells oscillate between promoting and inhibiting tumor activity, responding to a multitude of cytokines, chemokines, and tumor-derived factors. This response modulates immune reactions and affects the proliferation, metastasis, and angiogenesis of cancer cells. A significant aspect of their influence is their interaction with the endoplasmic reticulum (ER) stress responses in cancer cells, markedly altering tumor immunodynamics by modulating the phenotypic plasticity and functionality of neutrophils. Furthermore, neutrophil extracellular traps (NETs) exert a pivotal influence in the progression of malignancies by enhancing inflammation, metastasis, immune suppression, and thrombosis, thereby exacerbating the disease. In the realm of immunotherapy, checkpoint inhibitors targeting PD-L1/PD-1 and CTLA-4 among others have underscored the significant role of neutrophils in enhancing therapeutic responses. Recent research has highlighted the potential of using neutrophils for targeted drug delivery through nanoparticle systems, which precisely control drug release and significantly enhance antitumor efficacy. This review thoroughly examines the diverse functions of neutrophils in cancer treatment, emphasizing their potential in regulating immune therapy responses and as drug delivery carriers, offering innovative perspectives and profound implications for the development of targeted diagnostic and therapeutic strategies in oncology.

The role of lymphocyte-C-reactive protein ratio in the prognosis of gastrointestinal cancer: a systematic review and meta-analysis

Objective

The lymphocyte-to-C-reactive protein (LCR) ratio, an immune-inflammatory marker, shows prognostic potential in various cancers. However, its utility in gastrointestinal malignancies remains uncertain due to inconsistent findings. This systematic review and meta-analysis synthesizes recent evidence to elucidate the association between LCR and prognosis in gastrointestinal cancer patients, aiming to clarify LCR's potential role as a prognostic biomarker.

Methods

We searched PubMed, Embase, Cochrane, and Web of Science databases up to May 2024 to evaluate the association between LCR and prognosis in gastrointestinal cancer patients. The main outcomes included overall survival (OS), recurrence-free survival (RFS), and disease-free survival (DFS). We also analyzed secondary parameters such as geographical region, study duration, sample size, LCR threshold, and patient characteristics (age, gender, tumor location, and TNM stage).

Results

This meta-analysis of 21 cohort studies (n=9,131) finds a significant association between reduced LCR levels and poor prognosis in gastrointestinal cancer. Lower LCR levels were associated with worse overall survival (HR=2.01, 95% CI=1.75-2.31, P<0.001), recurrence-free survival (HR=1.90, 95% CI=1.32-2.76, P<0.001), and disease-free survival (HR=1.76, 95% CI=1.45-2.13, P<0.001). Subgroup analyses by cancer type, timing, and LCR threshold consistently confirmed this relationship (P<0.05).

Conclusion

LCR may serve as a prognostic marker in gastrointestinal cancer patients, with lower LCR levels associated with poorer prognosis. However, more high-quality studies are needed to validate these findings, considering the limitations of the current evidence.

Association between preoperative neutrophil-to-lymphocyte ratio and the survival outcomes of esophageal cancer patients underwent esophagectomy: a systematic review and meta-analysis

Objectives

The purpose of this study was to assess the association between preoperative neutrophil-to-lymphocyte ratio (NLR) and the survival outcomes of esophageal cancer patients who underwent esophagectomy, the latest and comprehensive systematic review performed.

Methods

Related literature retrieved from PubMed, Web of Science, Embase, and Cochrane before January 2024, according to the inclusion criteria. Outcomes measured were overall survival (OS), disease-free survival (DFS), relapse-free survival (RFS), and cancer-specific survival (CSS).

Results

Eighteen studies with 6,119 esophageal cancer patients were retained for analysis. Meta-analysis demonstrated that OS (HR: 1.47; 95% CI: 1.29, 1.67; P < 0.00001), DFS (HR: 1.62; 95% CI: 1.29, 2.05; P < 0.0001), and CSS (HR: 1.62; 95% CI: 1.29, 2.05; P < 0.0001) were significantly shorter in the high NLR group compared with the low NLR group. In addition, meta-analysis revealed a similar RFS (HR: 1.47; 95% CI: 0.92, 2.35; P = 0.10) among the two groups. Subgroup analysis of OS and DFS based on mean/median age, NLR cutoff, and region found that all subgroups remained significant difference between two groups.

Conclusion

Among esophageal cancer patients who underwent esophagectomy, preoperative NLR can be used as prognostic factor independently. High-preoperative NLR is associated with poor prognosis. More large-scale, multicenter prospective clinical studies are needed to further validate the relationship between preoperative NLR and prognosis of esophageal cancer.

The Biomarker Potential of the Neutrophil-to-Lymphocyte Ratio in Acute Exacerbation of Chronic Obstructive Pulmonary Disease

Background Chronic obstructive pulmonary disease (COPD) is characterized by periods of exacerbations and seasonal variations due to the recruitment of inflammatory cells. Various cells, such as neutrophils, lymphocytes, and the inflammatory mediators released by them, play a role in its pathogenesis. The current study was conducted to determine the role of the neutrophil-to-lymphocyte ratio (NLR) as a marker in acute exacerbation of COPD (AECOPD). Materials and methods We conducted a cross-sectional observational study at a tertiary care center in Western Maharashtra over six months after receiving approval from the institutional ethics committee. The study included 50 patients with AECOPD and 30 age and gender-matched controls without COPD. The patients were examined with a detailed history, complete blood count, and spirometry. The NLR was calculated and patients' disease severity was assessed using Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging. Results The mean age in the AECOPD group was 67.5 ± 12.5 years, whereas it was 46.2 ± 18.5 years in the control group. There was a male predominance in the AECOPD group (32/50). The majority of patients were in the GOLD stage 2 (42/50), followed by GOLD stage 3 (7/50). A total of 28 out of 50 AECOPD patients required admission to the medical intensive care unit. In the AECOPD group, 39 were smokers, and 11 were nonsmokers. Smoking was significantly associated with AECOPD when compared with controls. The mean NLR was 10.9 ± 10.2 in AECOPD patients and 4.3 ± 3.1 in the controls. Among cases with high NLR (≥5), seven required mechanical ventilation, 13 required noninvasive ventilation (NIV), and six succumbed to death. The mean duration of mechanical ventilation in this group was 12.5 ± 4.5 days, and for NIV, it was 7.5 ± 5.5 days. Conversely, patients with lower NLR (≤5) were more likely to avoid artificial ventilation and had a better in-hospital outcome. Conclusion COPD exacerbations can harm a patient's health, lead to disease progression, and increase mortality rates. Predicting exacerbations in advance can aid in early detection and treatment. NLR is an inexpensive, noninvasive, and easily available marker of inflammation and a predictor of outcome in AECOPD patients and hence should be calculated routinely in all patients with COPD.

Serum inflammatory markers as prognostic marker for nasopharyngeal carcinoma with liver metastasis: a multi-center retrospective study

BACKGROUND

This retrospective study investigated the prognostic value of serum inflammatory markers in nasopharyngeal carcinoma (NPC) patients, focusing on their association with overall survival (OS) and liver metastasis-free survival (LMFS).

METHODS

The study included 314 NPC patients treated between 2010 and 2020. Clinical characteristics, treatment methods, and serum inflammatory markers were assessed. Patients were categorized into two groups of with and without liver metastasis. Univariate and multivariate Cox regression and Kaplan-Meier survival analyses were performed to investigate the prognostic value of serum inflammatory markers in NPC patients with and without liver metastasis.

RESULTS

In the whole cohort, univariate Cox regression analysis singled out tumor necrosis factor-α (TNF-α) (HR = 1.57, 95% CI 1.44-4.90, p = 0.004) and neutrophil-to-lymphocyte ratio (NLR) (HR = 2.13, 95% CI 1.33-3.99, p = 0.009), which were significantly associated with poorer OS. In patients with liver metastasis, TNF-α and NLR could not independently predict OS. However, high TNF-α levels were independently associated with worse OS in patients without liver metastasis (HR (95% CI) = 2.75 (1.67-8.68), p < 0.001). High NLR levels could independently predict poor OS in both groups with (HR (95% CI) = 1.94 (1.77-6.38), p = 0.010) and without liver metastasis (HR (95% CI) = 1.58 (1.19-7.54), p = 0.009). Ultimately, TNF-α and NLR could not significantly predict LMFS.

CONCLUSION

This study highlights the prognostic significance of TNF-α and NLR in NPC patients, especially in those with liver metastasis. These inflammatory markers could serve as valuable indicators for assessing the prognosis of NPC patients. Further research is warranted to validate their clinical utility and explore potential therapeutic implications.

Can Chinese herbal medicine offer feasible solutions for newly diagnosed esophageal cancer patients with malnutrition? a multi-institutional real-world study

Background

Esophageal cancer (EC) is a major cause of cancer-related mortality in Taiwan and globally. Patients with EC are highly prone to malnutrition, which adversely affects their prognosis. While Chinese herbal medicine (CHM) is commonly used alongside conventional anti-cancer treatments, its long-term impact on EC patients with malnutrition remains unclear.

Methods

This study utilized a multi-center cohort from the Chang Gung Research Database, focusing on the long-term outcomes of CHM in EC patients with malnutrition between 1 January 2001, and 31 December 2018. Patients were monitored for up to 5 years or until death. Overall survival (OS) rates were calculated using the Kaplan-Meier method. Overlap weighting and landmark analysis were employed to address confounding and immortal time biases. Additionally, the study analyzed prescription data using a CHM network to identify key CHMs for EC with malnutrition, and potential molecular pathways were investigated using the Reactome database.

Results

EC patients with malnutrition who used CHM had a higher 5-year OS compared with nonusers (22.5% vs. 9% without overlap weighting; 24.3% vs. 13.3% with overlap weighting; log-rank test: p = 0.006 and 0.016, respectively). The median OS of CHM users was significantly longer than that of nonusers (19.8 vs. 12.9 months, respectively). Hazard ratio (HR) analysis showed a 31% reduction in all-cause mortality risk for CHM users compared with nonusers (HR: 0.69, 95% confidence interval: 0.50-0.94, p = 0.019). We also examined 665 prescriptions involving 306 CHM, with Hedyotis diffusa Willd. exhibiting the highest frequency of use. A CHM network was created to determine the primary CHMs and their combinations. The identified CHMs were associated with the regulation of immune and metabolic pathways, particularly in areas related to immune modulation, anti-cancer cachexia, promotion of digestion, and anti-tumor activity.

Conclusion

The results of this study suggest a correlation between CHM use and improved clinical outcomes in EC patients with malnutrition. The analysis identified core CHMs and combinations of formulations that play a crucial role in immunomodulation and metabolic regulation. These findings lay the groundwork for more extensive research on the use of CHM for the management of malnutrition in patients with EC.

The clinical impacts of the prognostic nutritional index for the esophageal cancer patients who received curative treatment

BACKGROUND

We investigated the impact of the prognostic nutritional index (PNI) on esophageal cancer survival and recurrence after curative treatment.

METHODS

This study included 120 patients who underwent curative surgery followed by the adjuvant treatment for esophageal cancer between 2008 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified.

RESULTS

The PNI of 49 was regarded to be the optimal critical point of classification considering the 1-year, 3-year, and 5-year survival rate. The OS rates at three and five years after surgery were 47.4% and 36.0% in the PNI low group, respectively, and 62.5% and 56.5% in the PNI high group, which amounted to a statistically significant difference ( P = 0.020). The RFS rates at three and five years after surgery were 31.0% and 24.8% in the PNI low group, respectively, and 50.9% and 42.8% in the PNI high group, which amounted to a statistically significant difference ( P = 0.020). A multivariate analysis demonstrated that the PNI was a significant independent risk factor for the OS and a marginally significant independent risk factor forRFS.

CONCLUSION

The PNI was a risk factor for survival in patients who underwent curative treatment for esophageal cancer. It is necessary to develop the effective plan of the perioperative care and the surgical strategy according to the PNI.

The role of preoperative hematological inflammatory markers as a predictor of meningioma grade: A systematic review and meta-analysis

Background

Inflammatory processes play an important role in the aggressiveness of a tumor. However, the relationship between inflammatory markers in meningioma grade is not well known. Knowledge of preoperative meningioma grade plays an important role in the prognosis and treatment of this tumor. This study aims to assess preoperative hematological inflammatory markers as a predictor of the pathological grade of meningioma.

Methods

To ensure comprehensive retrieval of relevant studies, we searched the following key databases, PubMed, Science Direct, and Biomed Central, with evidence related to preoperative hematological inflammatory markers among meningioma up to September 2023. The studies involved were selected based on established eligibility criteria. The analysis in this study uses Review Manager 5.4.

Results

Six studies were obtained from the search results. The total number of patients 2789 (469 high-grade meningioma and 2320 low-grade meningioma) analysis shows elevated neutrophil-to-lymphocyte ratio (NLR) (mean difference [MD]: 0.29; 95% confidence interval [CI] 0.13-0.45; P = 0.0004), monocyte-to-lymphocyte ratio (MLR) (MD: 0.02; 95% CI 0.00-0.04; P = 0.003), and low lymphocyte-to-monocyte ratio (LMR) (MD: -0.82; 95% CI -1.46--0.18; P = 0.005) significantly associated with high-grade meningioma compared to low-grade meningioma. No significant correlation between high-grade and low-grade meningioma based on platelet-lymphocyte ratio value is observed.

Conclusion

The parameters of NLR, MLR, and LMR have been found to be cost-effective preoperative methods that demonstrate potential value in the prediction of meningioma grade. To enhance the reliability of the findings, it is imperative to do further prospective study.

Survival Predictors Before Preoperative Adjuvant Chemotherapy in Patients With Locally Advanced Esophageal Squamous Cell Carcinoma

BACKGROUND/AIM

Radical resection after preoperative adjuvant chemotherapy (NAC) is a standard treatment for patients with locally advanced esophageal squamous cell carcinoma (LAESCC), but its outcome remains unsatisfactory. In order to develop a personalized treatment program for LAES, we herein compared the survival prediction utility of five pre-NAC nutritional, inflammatory, and immune indexes in patients with LAESCC.

PATIENTS AND METHODS

We evaluated the survival of 203 patients with LAESCC who underwent radical resection after NAC from January 2011 to September 2019 for the following representative pre-NAC nutritional, inflammatory, and immune indices: modified Glasgow Prognostic Score, Prognostic Nutritional Index, C-reactive protein/albumin ratio, serum neutrophil/lymphocyte ratio, and Geriatric Nutrition Risk Index (GNRI) were evaluated for their impact on survival.

RESULTS

Of the five indices, GNRI was the best predictor of survival as determined by the area under the curve (p<0.05). When patients were divided into three groups according to the nutritional risk assessment of Bouillanne et al. using the pre-NAC GNRI, the 5-year overall survival (OS) and recurrence-free survival (RFS) were significantly stratified (p<0.001). On multivariate analysis, the GNRI independently identified a poor OS group [group 1: hazard ratio (HR)=2.598, p=0.002; group 2: HR=6.257, p<0.001] and a high recurrence risk group (group 1: HR=1.967, p=0.016; group 2: HR=4.467, p<0.001).

CONCLUSION

In patients with LAESCC, GNRI may be the most accurate, reliable, and useful prognostic factor among the five major systemic inflammatory and nutritional indices.

Monitoring trends in the absolute lymphocyte count and the neutrophil-to-lymphocyte ratio in patients with breast cancer receiving eribulin

BACKGROUND

Studies have shown that the absolute lymphocyte count (ALC) and the neutrophil-to-lymphocyte ratio (NLR) are related to the outcomes in patients with breast cancer receiving specific chemotherapies. However, the reports have focussed on the initial blood test and there is a lack of evidence or data to support that dynamic changes of ALC or NLR are associated with the patients' survival outcomes.

METHODS

We retrospectively reviewed electronic medical records from patients with breast cancer treated with eribulin from 2015 to 2019 at our institution. Blood test data were available prior to starting eribulin (baseline), and at 1, 3 and 6 months after initiating eribulin. We classified the patients into ALC and NLR high and low groups using the following cut-offs: 1000/µl for ALC and 3 for NLR. We defined ALC and NLR trends as increasing or decreasing compared with the initial data. We assessed the associations between the ALC and NLR with progression-free survival and overall survival.

RESULTS

There were 136 patients with breast cancer treated with eribulin. Of these patients, 60 had complete blood tests and follow-up data. Neither a high ALC nor a low baseline NLR was associated with the survival outcome. One month after initiating eribulin treatment, a high ALC and a low NLR were significantly associated with longer progression-free survival (p = 0.044 for each). Three months after initiating eribulin, a high ALC was significantly associated with better overall survival (p = 0.006). A high NLR at 3 or 6 months after initiating eribulin was associated with worse overall survival (p = 0.017 and p = 0.001, respectively). The ALC and NLR trends across times were not associated with survivals.

CONCLUSION

We showed that 1, 3 and 6 months after initiating eribulin, a high ALC and a low NLR may be related to the patients' survival outcomes. The ALC and NLR trends were not associated with survival. Accordingly, we believe patients who maintain a high ALC and a low NLR may have better clinical outcomes after initiating eribulin.

Clinical Significance of the Preoperative Inflammatory Burden Index in Esophageal Cancer

INTRODUCTION

The inflammatory burden index (IBI) serves as a prognostic marker for several cancers. Here, we evaluated the predictive value of preoperative IBI associated with the surgical and oncological outcomes of patients with esophageal cancer (EC).

METHODS

The IBI was formulated as C-reactive protein × neutrophil/lymphocyte. We retrospectively analyzed preoperative IBI of 147 EC patients receiving esophagectomy between 2008 and 2018. Cox proportional hazards models and multivariable logistic regression were employed to identify independent risk factors of surgical site infection and prognosis.

RESULTS

Increased preoperative IBI significantly correlated with higher tumor stage. Patients with high IBI experienced shorter overall survival (p = 0.0002) and disease-free survival (p = 0.002) compared with those with low IBI. In the adjusted Cox proportional hazards regression models, increased IBI served as an independent prognostic factor for overall survival (hazard ratio, 3.56; 95% confidence interval, 1.79-7.34; p = 0.0003) and disease-free survival (hazard ratio, 3.03; 95% confidence interval, 1.60-5.92; p = 0.007). Multivariable analysis identified preoperative high IBI which served as an independent risk factor for overall surgical site infection (odds ratio, 2.53; 95% confidence interval, 1.00-6.38; p = 0.049).

CONCLUSION

Preoperative IBI may serve as a useful predictor of prognosis and surgical site infection of patients with EC after esophagectomy.

Neutrophil to Lymphocyte Ratio as a Prognostic Marker in Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS) is the most common neurodegenerative motor neuron disease and remains misunderstood with a difficult diagnosis and prognosis. The implication of the immune system is recognized in ALS pathophysiology, hence the interest in leucocyte count as lymphocytes and neutrophils. The neutrophil-to-lymphocyte ratio (NLR) has recently been used as a prognosis factor to assess the progression of ALS. Thus, the aim of this study was to analyze the evolution of the NLR during disease evolution in a French cohort of ALS patients and its relation with survival. In this monocentric retrospective study, clinical parameters and NLR were collected in ALS patients followed at the University Hospital of Tours (France). ALS patients were subdivided into three groups regarding their NLR value at inclusion: group 1 (NLR < 2); group 2 (NLR: 2-3); group 3 (NLR > 3). A comparison of qualitative and quantitative clinical and biological variables between NLR groups was performed. Then, Cox regressions were carried out to determine the association of NLR with survival. We observed a significant correlation of NLR with ALSFRS-r score (p < 0.0001) and with vital forced capacity (p = 0.0004) at inclusion. We observed that increased NLR at diagnosis is associated with decreased ALS patients' survival.

Cardiac Dose Predicts the Response to Concurrent Chemoradiotherapy in Esophageal Squamous Cell Carcinoma

Definitive concurrent chemoradiation (CCRT) is the standard treatment for cervical esophageal cancer and non-surgical candidates. Initial treatment response affects survival; however, few validated markers are available for prediction. This study evaluated the clinical variables and chemoradiation parameters associated with treatment response. Between May 2010 and April 2016, 86 completed CCRT patients' clinical, dosimetric, and laboratory data at baseline and during treatment were collected. Cox regression analysis assessed the risk factors for overall survival (OS). A receiver operating characteristic curve with Youden's index was chosen to obtain the optimal cut-off value of each parameter. Treatment response was defined per Response Evaluation Criteria in Solid Tumors v.1.1 at the first post-CCRT computed tomography scan. Responders had complete and partial responses; non-responders had stable and progressive diseases. Logistic regression (LR) was used to evaluate the variables associated with responders. The Cox regression model confirmed the presence of responders (n = 50) vs. non-responders (n = 36) with a significant difference in OS. In multivariate LR, cardiac dose-volume received ≥10 Gy; the baseline hemoglobin level, highest neutrophil to lymphocyte ratio during CCRT, and cumulative cisplatin dose were significantly associated with the responders. The initial clinical treatment response significantly determines disease outcome. Cardiac irradiation may affect the treatment response.

Establishment and validation of a prognostic risk classification for patients with stage T1-3N0M0 esophageal squamous cell carcinoma

INTRODUCTION

At present, clinical factors and hematological indicators have been proved to have great potential in predicting the prognosis of cancer patients, and no one has combined these two valuable indicators to establish a prognostic model for esophageal squamous cell carcinoma (ESCC) patients with stage T1-3N0M0 after R0 resection. To verify, we aimed to combine these potential indicators to establish a prognostic model.

METHODS

Stage T1-3N0M0 ESCC patients from two cancer centers (including training cohort: N = 819, and an external validation cohort: N = 177)-who had undergone esophagectomy in 1995-2015 were included. We integrated significant risk factors for death events by multivariable logistic regression methods and applied them to the training cohort to build Esorisk. The parsimonious aggregate Esorisk score was calculated for each patient; the training set was divided into three prognostic risk classes according to the 33rd and 66th percentiles of the Esorisk score. The association of Esorisk with cancer-specific survival (CSS) was assessed using Cox regression analyses.

RESULTS

The Esorisk model was: [10 + 0.023 × age + 0.517 × drinking history - 0.012 × hemoglobin-0.042 × albumin - 0.032 × lymph nodes]. Patients were grouped into three classes-Class A (5.14-7.26, low risk), Class B (7.27-7.70, middle risk), and Class C (7.71-9.29, high risk). In the training group, five-year CSS decreased across the categories (A: 63%; B: 52%; C: 30%, Log-rank P < 0.001). Similar findings were observed in the validation group. Additionally, Cox regression analysis showed that Esorisk aggregate score remained significantly associated with CSS in the training cohort and validation cohort after adjusting for other confounders.

CONCLUSIONS

We combined the data of two large clinical centers, and comprehensively considered their valuable clinical factors and hematological indicators, established and verified a new prognostic risk classification that can predict CSS of stage T1-3N0M0 ESCC patients.

The predictive value of perioperative circulating markers on surgical complications in patients undergoing robotic-assisted radical prostatectomy

BACKGROUND

The occurrence of postoperative complications was associated with poor outcomes for patients undergoing robotic-assisted radical prostatectomy. A prediction model with easily accessible indices could provide valuable information for surgeons. This study aims to identify novel predictive circulating biomarkers significantly associated with surgical complications.

METHODS

We consecutively assessed all multiport robotic-assisted radical prostatectomies performed between 2021 and 2022. The clinicopathological factors and perioperative levels of multiple circulating markers were retrospectively obtained from the included patients. The associations of these indices with Clavien-Dindo grade II or greater complications, and surgical site infection were assessed using univariable and multivariable logistic regression models. Further, the models were validated for the overall performance, discrimination, and calibration.

RESULTS

In total, 229 patients with prostate cancer were enrolled in this study. Prolonged operative time could independently predict surgical site infection (OR, 3.39; 95% CI, 1.09-10.54). Higher RBC (day 1-pre) implied lower risks of grade II or greater complications (OR, 0.24; 95% CI, 0.07-0.76) and surgical site infection (OR, 0.23; 95% CI, 0.07-0.78). Additionally, RBC (day 1-pre) independently predicted grade II or greater complications of obese patients (P value = 0.005) as well as those in higher NCCN risk groups (P value = 0.012). Regarding the inflammatory markers, NLR (day 1-pre) (OR, 3.56; 95% CI, 1.37-9.21) and CRP (day 1-pre) (OR, 4.16; 95% CI, 1.69-10.23) were significantly associated with the risk of grade II or greater complications, and both the indices were independent predictors in those with higher Gleason score, or in higher NCCN risk groups (P value < 0.05). The NLR (day 0-pre) could also predict the occurrence of surgical site infection (OR, 5.04; 95% CI, 1.07-23.74).

CONCLUSIONS

The study successfully identified novel circulating markers to assess the risk of surgical complications. Postoperative increase of NLR and CRP were independent predictors for grade II or greater complications, especially in those with higher Gleason score, or in higher NCCN risk groups. Additionally, a marked decrease of RBC after the surgery also indicated a higher possibility of surgical complications, especially for the relatively difficult procedures.

The clinical impacts of lymphocyte-to-C-reactive protein ratio for esophageal cancer patients who receive curative treatment

Background

We investigated the impact of the lymphocyte-to-C-reactive protein ratio (LCR) on esophageal cancer survival and recurrence after curative treatment.

Patients and Methods

This study included 89 patients who underwent curative surgery followed by adjuvant treatment for esophageal cancer between 2008 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified.

Results

LCR of 12,177 was regarded to be the optimal critical point of classification considering the 1-year, 3-year, and 5-year survival rates. The OS rates at 3 and 5 years after surgery were 33.2% and 29.9% in the LCR low group, respectively, and 74.0% and 60.9% in the LCR high group, which amounted to a statistically significant difference (P = 0.001). The RFS rates at 3 and 5 years after surgery were 25.3% and 21.7% in the LCR low group, respectively, and 52.1% and 47.4% in the LCR high group, which amounted to a statistically significant difference (P = 0.001). A multivariate analysis demonstrated that the LCR was a significant independent risk factor for both the OS and RFS.

Conclusion

LCR was a risk factor for survival in patients who underwent curative treatment for esophageal cancer. It is necessary to develop the effective plan of the perioperative care and the surgical strategy according to the LCR.

Impact of early postoperative factors on changes in skeletal muscle mass after esophagectomy in older patients with esophageal cancer

BACKGROUND

Loss of skeletal muscle mass, measured by the skeletal muscle mass index (SMI), after esophagectomy negatively impacts prognosis. However, the information to develop novel supportive care options for preventing loss of skeletal muscle mass is limited. The purpose of this retrospective cohort study was to investigate the impact of early postoperative factors on change in SMI 4 months after curative esophagectomy in older patients with esophageal cancer.

METHODS

This study included 113 subjects who underwent esophagectomy between 2015 and 2020. Preoperative and postoperative SMI (cm²/m²) were calculated from computed tomography images. The percentage change in SMI 4 months after surgery (SMI%) was calculated as follows: ([postoperative SMI - preoperative SMI] ÷ preoperative SMI) × 100. Potential factors affecting percentage change of SMI after surgery were analyzed by multiple regression.

RESULTS

The mean SMI% was - 5.6%. The percentage change (per 1%) in quadriceps muscle strength in the first month after surgery (standardized β = 0.190, p = 0.048) impacted the SMI%, which was independent of age, sex, preoperative SMI, comorbidity, pathological stage, and neoadjuvant chemotherapy.

CONCLUSION

Quadriceps muscle weakness in the first month after esophagectomy impacted the SMI% in a dose-dependent relationship.

The effect of haemoglobin, albumin, lymphocyte and platelet score on the prognosis in patients with multiple myeloma

INTRODUCTION

In multiple myeloma cases, a variety of prognostic parameters have been identified, which contain the Durie-Salmon classification and the international staging system (ISS) that takes the serum ß2 microglobulin and albumin levels, platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and monocyte-to-lymphocyte ratio (MLR). This study investigates the effect of haemoglobin, albumin, lymphocyte and platelet (HALP) score which is a marker of inflammation status and nutrition, at the time of diagnosis for the patients with multiple myeloma on prognosis.

METHODS

A total of 200 multiple myeloma patients with HALP scores calculated from serum haemoglobin, albumin, lymphocyte count and platelet levels at the time of diagnosis were retrospectively examined. The effect of HALP score on overall survival (OS) and progression-free survival and its relationship between the previously evaluated prognostic parameters were investigated.

RESULTS

The optimal cut-off value with the ROC curves for the HALP score was 28.8. The patients were divided into two groups according to the optimal value of the HALP score (low-score group: HALP ≤28.8 [n: 134] and high-score group HALP >28.8 [n: 66]). In the group with the high HALP score, the OS was statistically longer than the low HALP score group (84 months and 53 months; p = 0.0001). In addition, when the effects of NLR, PLR, HALP score and ISS stage on OS were examined by multivariate analysis, all these markers were found to be statistically significant predictors.

CONCLUSIONS

HALP score may be a valuable prognostic marker for patients with multiple myeloma.

Usefulness of Nutrition and Inflammation Assessment Tools in Esophageal Cancer Treatment

Multidisciplinary treatment for esophageal cancer leads to nutritional and inflammatory changes. Recent studies showed that nutritional and inflammatory changes during multidisciplinary treatment affect both short and long-term oncological outcomes in esophageal cancer treatment. Therefore, evaluation of the nutritional and inflammatory status during treatment is necessary in order to optimize and utilize multidisciplinary therapy for esophageal cancer. If patients with esophageal cancer are able to determine their nutritional and inflammatory status, they will be able to select the optimal esophageal cancer, anti-inflammation, and nutritional treatments. Various types of nutrition and inflammation assessment tools have been developed and reported for esophageal cancer, with each tool having its own clinical characteristics, which must be understood before being applied in clinical practice. This review summarizes the background, current status, and future perspectives on the application of nutrition and inflammation assessment tools in esophageal cancer treatment.

Biomarkers for immunotherapy in esophageal cancer

The development of immunotherapy, especially immune-checkpoint inhibitors targeting PD-1/PD-L1, has improved the outcomes of patients with esophageal cancer. However, not all population derives benefit from the agents. Recently, kinds of biomarkers were introduced to predict the response to immunotherapy. However, the effects of these reported biomarkers are controversial and many challenges remain. In this review, we aim to summarize the current clinical evidence and provide a comprehensive understanding of the reported biomarkers. We also discuss the limits of the present biomarkers and propose our own opinions on which viewers' discretion are advised.

Prognostic value of inflammatory markers and clinical features for survival in advanced or metastatic esophageal squamous cell carcinoma patients receiving anti-programmed death 1 treatment

Purpose

This study aims to assess the prognostic value of inflammatory markers and clinical features in advanced or metastatic esophageal squamous cell carcinoma (ESCC) patients receiving anti-programmed death 1 (PD-1) treatment.

Methods

Based on receiver operating characteristic curve (ROC) analysis, Youden's indexes were applied to determine the cut-off values for inflammatory markers, including neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocye ratio (dNLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII). Wilcoxon test was conducted to evaluate the changes in above inflammatory markers. Kaplan-Meier method was utilized to estimate progression-free survival (PFS) and overall survival (OS), and the Log-rank test was used to compare the different survival between groups. Univariate and multivariate Cox regression analyses were performed to assess the prognostic value of inflammatory markers and clinical features.

Results

162 advanced or metastatic ESCC patients receiving anti-PD-1 treatment were enrolled in this retrospective study. The cut-off values of NLR, dNLR, MLR, PLR, and SII were 4.748, 2.214, 0.309, 250.505, and 887.895, respectively. NLR, dNLR, PLR, and SII declined significantly among the partial response (PR) (P<0.001, P<0.001, P=0.036, P<0.001), objective response rate (ORR) (P<0.001, P<0.001, P=0.036, P<0.001), and disease control rate (DCR) (P<0.001, P<0.001, P=0.038, P<0.001) groups, respectively. Significant increases were found in NLR (P<0.001), dNLR (P<0.001), MLR (P=0.001), and SII (P=0.024) when anti-PD-1 treatment failed. Multivariate Cox regression analysis indicated that NLR (P<0.001, P=0.002), lymph node metastasis (P=0.013, P=0.001), Eastern Cooperative Oncology Group Performance Status (ECOG PS) (P=0.008, P=0.002), and treatment lines (P=0.037, P=0.048) were significant prognostic indicators of PFS and OS. Additionally, SII (P=0.016) was also significantly related to OS in ESCC patients. The risk score model showed that low risk patients prolonged PFS and OS than those with middle or high risk (P<0.001, P<0.001).

Conclusion

Inflammatory markers can reflect short-term outcomes of anti-PD-1 treatment for ESCC patients. NLR, lymph node metastases, ECOG PS, and treatment lines are significant prognostic indicators for PFS and OS. And the risk score model constructed based on the above factors has favourable prognostic predictive value.

The impact of nutritional status in nivolumab-treated patients with advanced esophageal cancer

Although phase III trials have reported improved overall survival in patients with advanced esophageal squamous cell carcinoma following treatment with nivolumab, as compared with chemotherapy (paclitaxel or docetaxel), the treatment was effective only in a limited number of patients. Therefore, the aim of this study is to determine whether there is a correlation between nutritional status (Glasgow prognostic score, prognostic nutritional index, and neutrophil-to-lymphocyte ratio) and prognosis of advanced esophageal cancer in patients treated with taxane or nivolumab therapy. The medical records of 35 patients who received taxane monotherapy (paclitaxel or docetaxel), for advanced esophageal cancer between October 2016 and November 2018 (taxane cohort) were reviewed. The clinical data of 37 patients who received nivolumab therapy between March 2020 and September 2021 (nivolumab cohort) were collected. The median overall survival was 9.1 months for the taxane cohort and 12.5 months for the nivolumab cohort. In the nivolumab cohort, patients with good nutritional status had significantly better median overall survival than those with poor nutritional status (18.1 vs. 7.6 months, respectively, p = 0.009, classified by prognostic nutritional index, 15.5 vs. 4.3 months, respectively, p = 0.012, classified by Glasgow prognostic score), whereas the prognosis of the patients treated with taxane therapy was less affected by the nutritional status. This suggests that the pretreatment nutritional status of patients with advanced esophageal cancer is a key factor for successful outcomes, especially for treatment with nivolumab.

Neutrophil to lymphocyte ratio (NLR) impact on the progression-free survival and overall survival of multiple myeloma patients treated with high-dose chemotherapy and autologous stem cell transplantation

High-dose chemotherapy with autologous stem-cell transplantation (ASCT) remains the standard of care in multiple myeloma (MM) patients. This retrospective study aimed to assess the impact of neutrophil-to-lymphocyte ratio (NLR) and other complete blood count (CBC)-based predictors on PFS and OS of transplant-eligible MM patients. The CBC-based biomarkers were evaluated in a single-center cohort of 176 MM patients at three time points: at the diagnosis, the time of ASCT, and +100 d after ASCT. Univariable and multivariable Cox's regression analyses and Kaplan-Meier estimate were used in statistical analysis. NLR at ASCT (HR 1.15, 95% CI: 1.05-1.26) and hemoglobin at ASCT (HR 0.80, 95% CI: 0.68-0.94) were independent factors influencing PFS. In the model for OS, the only statistically significant factors were NLR at ASCT (HR 1.15, 95% CI: 1.04-1.27), bortezomib administration prior to ASCT (HR 0.52, 95% CI: 0.33-0.83) and age at diagnosis (HR 1.03, 95% CI: 1.00-1.06). NLR at ASCT is an independent predictive factor in MM patients undergoing ASCT.

Neutrophil-to-lymphocyte ratio after neoadjuvant chemotherapy as an independent prognostic factor in patients with esophageal squamous cell carcinoma

Studies have shown that neoadjuvant chemotherapy (NAC) followed by surgical resection improves the survival of patients with esophageal squamous cell carcinoma (ESCC), and that the neutrophil-to-lymphocyte ratio (NLR) nay be a prognostic biomarker in various types of cancer. Despite the noTable changes in the tumor and its microenvironment during NAC, it remains unclear how the NLR changes and which values (before or after NAC) best predict prognosis. The present study aimed to analyze changes in the NLR before and after NAC, and to determine which was a better prognostic factor. This study retrospectively analyzed 338 consecutive patients with ESCC who received NAC followed by curative resection. NLRs before (pre-NLR) and after (post-NLR) NAC were calculated, after which the impact of NAC on NLR, overall survival (OS) and recurrence-free survival (RFS), as well as the relationship between hematological toxicities and NLR, was evaluated. Cutoff values for pre- and post-NLR were 3.7 and 2.5, respectively. Patients with high post-NLR had a worse OS (P=0.0001) and 3-year RFS (P=0.03) than those with low post-NLR. Multivariate analysis identified high post-NLR, pN1 and clinical response as independent prognostic factors. In conclusion, post-NLR was revealed as a better prognostic factor than pre-NLR for patients receiving NAC followed by surgical resection.

Neutrophil-lymphocyte ratio as a risk factor for osteoporotic vertebrae fractures and femoral neck fractures

Fracture is associated with osteopenia after osteoporosis. Neutrophil-lymphocyte ratio (NLR) is common in inflammatory diseases. NLR can be used as an effective clinical tool to assess postmenopausal osteoporosis. The aim of this study is to further explore the relationship between elevated NLR and the severity of osteoporotic vertebrae fractures and femoral neck fracture based on magnetic resonance imaging (MRI). A total of 80 patients with osteoporotic vertebrae fractures, osteoporotic femoral neck fracture in Baoding Second Central Hospital from 2017 to 2020 were selected as the research objects. This study included a series of pretreatment factors, mainly including white blood cell count, red blood cell count, hemoglobin, and the general condition of the patients. Statistical methods included Pearson chi-square test, Spearman correlation test, logistic regression analysis and receiver operator characteristic (ROC) curve. According to Pearson chi-square test, Spearman correlation test, univariate/multivariate logistic regression analysis, the severity of osteoporotic vertebrae fractures, osteoporotic femoral neck fracture was significantly correlated with NLR (P < .001). NLR (odds ratio [OR] = 13.229, 95% CI: 4.167-41.998, P < .001) was a significant independent risk factor for osteoporotic vertebrae fractures, osteoporotic femoral neck fracture. receiver operator characteristic (ROC) curve was used to detect the specificity and sensitivity. The level of NLR has an important influence on the severity of osteoporotic vertebrae fractures and femoral neck fracture. The higher the level of NLR, the more serious the osteoporotic vertebrae fractures and femoral neck fracture.

Elevated Platelet-to-Lymphocyte Ratio and Neutrophil-to-Lymphocyte Ratio after First Cycle of Chemotherapy and Better Survival in Esophageal Cancer Patients Receiving Concurrent Chemoradiotherapy

Background: Prognostic factors for poor survival have been proposed in esophageal squamous cell carcinoma (SCC) patients receiving concurrent chemoradiotherapy (CCRT). We conducted a retrospective study on hematological profile after first cycle of chemotherapy for esophageal SCC patients receiving CCRT. Methods: From January 2008 to December 2017, a total of 420 patients with esophageal SCC were enrolled. All included patients had undergone CCRT. Complete blood count, differential count, NLR, and PLR before chemotherapy (CHT) and after first cycle of CHT were obtained. Univariate and multivariate Cox regression analyses were used to assess the association between survival and patient, disease, and treatment characteristics. Results: On univariate analysis, significant factors for overall survival (OS) and disease specific survival (DSS) included ECOG performance status, clinical staging, operation, cisplatin dose, prechemotherapy NLR and PLR, and elevated postchemotherapy NLR. On multivariate analysis, ECOG performance status 0-I, Clinical staging I-II, Operation, cisplatin dose >150 mg/m², prechemotherapy PLR <375, and postchemotherapy platelet count ≥150 × 10⁹/L were independent factors for predicting better OS. Independent factors for predicting better DSS included ECOG performance status 0-I, Clinical staging I-II, Operation, cisplatin dose >150 mg/m², and prechemotherapy PLR <375. Conclusions: Our study showed that low levels of prechemotherapy PLR and NLR were associated with better OS and DSS. Elevated platelet count and NLR after first cycle of CHT were associated with better OS. Elevated PLR and NLR after first cycle of CHT were associated with better DSS.

Blood monocyte counts as a prognostic biomarker and predictor in Chinese patients with idiopathic pulmonary fibrosis

OBJECTIVES

We sought to evaluate the prognostic value of blood routine parameters and biochemical parameters, especially inflammation-related biomarkers, and establish an inflammation-related prognostic model in Chinese patients with idiopathic pulmonary fibrosis (IPF).

MATERIAL/METHODS

Patients diagnosed as IPF at Beijing Chaoyang Hospital and aged 40 years and older were consecutively enrolled from June 2000 to March 2015, and finally, a total of 377 patients were enrolled in the derivation cohort. The follow-up ended in December 2016. We used Cox proportional hazard model to calculate the hazard ratio (HR) and establish the prognostic model. The discrimination and calibration of the prognostic model were evaluated in an independent validation cohort enrolled from China-Japan Friendship Hospital between January 2015 and December 2019.

RESULTS

Multivariate analysis revealed that patients with elevated monocyte-to-red blood cell count ratio (MRR) and monocyte counts showed increased risk of mortality. The clinical-physiological-biomarker (CPB) index and CPB stage we established in this study were a significant predictor, and the C-index for CPB index and CPB stage in the validation cohort was 0.635 (95% CI: 0.558-0.712) and 0.619 (95% CI: 0.544-0.694), respectively. Patients in CPB stage III had the poorest survival.

CONCLUSION

We developed and validated a new inflammation-related prognostic model (CPB index and CPB stage) which was integration of age, gender, FVC (%, predicted), DLCO (%, predicted), Charlson Comorbidity Index, and blood monocyte counts. This prediction model exhibited strong ability in predicting mortality in Chinese patients with IPF.

Higher pre-treatment skin sympathetic nerve activity and elevated resting heart rate after chemoradiotherapy predict worse esophageal cancer outcomes

Background

Chemoradiotherapy (CRT), which might affect the autonomic system, is the mainstay therapy for advanced esophageal squamous cell carcinoma (ESCC). Autonomic dysfunction has been found to possibly lead to cancer mortality in those with elevated resting heart rates (RHR). Skin sympathetic nerve activity (SKNA) is a new method of stimulating electrical signals in skin to evaluate autonomic function from sympathetic tone. In this study, we investigated the association between changes in RHR and autonomic function and ESCC mortality.

Methods

Thirty-nine stage II-IV ESCC patients receiving CRT between March 2019 and November 2020 were prospectively enrolled and carefully selected, followed up and received the same meticulous supportive care. Serial RHR was recorded every two weeks from before CRT to eight weeks after CRT and average SKNA were recorded before and four weeks after CRT. All-cause mortality was defined as primary outcome.

Results

We found the RHR of ESCC patients to be significantly elevated and peaking at four weeks after CRT (p < 0.001) and then to gradually decrease. Those with an elevated RHR above the cutoff level (18 beat-per-minute) at eight weeks after CRT had worse overall survival. In addition, those with higher baseline sympathetic tone (average SKNA ≥ 0.86 μV) also had poor outcome.

Conclusions

Increased pre-treatment sympathetic tone and elevated RHR after CRT are alarm signs of poor ESCC outcome. Further exploration of the mechanisms underlying these associations could potentially lead to intervention strategies for reducing mortality.

The association between mortality and use of Chinese herbal medicine among incident stage IV esophageal cancer patients: A retrospective cohort study with core herbs exploration

Esophageal cancer (EC) remains a leading cause of death worldwide and in Taiwan. The prognosis of advanced-stage EC is notably poor, and the treatment options are limited. Chinese herbal medicine (CHM) has been widely used as a complementary treatment for cancer, yet the long-term effect of CHM in stage IV EC remains unclear. The multi-institutional cohort obtained from the Chang Gung research database (CGRD) was used to study the long-term outcome of CHM use among incident stage IV EC patients from 1 January 2002, to 31 December 2018. All patients were followed up to 5 years or the occurrence of death. The overall survival (OS) and disease-specific survival rates were conducted using Kaplan-Meier estimation. Overlap weighing and landmark analysis were used to eliminate confounding and immortal time biases. Furthermore, we demonstrated the core CHMs for stage IV EC by using the Chinese herbal medicine network (CMN) analysis on prescriptions. Nine hundred eighty-five stage IV EC patients were analyzed, including 74 CHM users and 911 non-CHM users. We found the use of CHM was associated with a higher 5-year overall survival rate than CHM nonusers (the cumulative probability: 19.52% versus 6.04%, log-rank test: p < 0.001, and the p < 0.001 with overlap weighting). In addition, the overall median survival time was about 7 months longer among CHM users. Moreover, the lower 1-, 3-, 5-year disease-specific survival rates were higher among CHM users. Additionally, the risk of all-cause mortality was lower among CHM users when considering accessible demographic covariates (adjusted hazard ratio: 0.59, 95%CI: 0.39, 0.89, p = 0.011). Furthermore, the CMN analysis revealed that CHMs improved health while relieving tumor burden. For example, Hedyotis diffusa Willd . was the core CHM with an anti-cancer effect, while Fritillaria thunbergii Miq and Sevilla maindronide Rochebrune were used together to relieve cancer-related gastrointestinal discomfort. The use of CHM seems safe and possibly beneficial among stage IV EC patients with a higher 5-year OS. Further clinical trials on CHM were guaranteed to explore the role of CHM in managing stage IV EC patients.

Association of low skeletal muscle mass and systemic inflammation with surgical complications and survival after microvascular flap reconstruction in patients with head and neck cancer

BACKGROUND

Skeletal muscle mass (SMM) and chronic inflammation are associated with postoperative complications and survival.

METHODS

Patients with head and neck cancer (HNC) undergoing microvascular free flap reconstruction were included. SMM and neutrophil-to-lymphocyte ratio (NLR) were measured and their association with treatment outcomes analyzed.

RESULTS

Five hundred and fifty-four patients were included. Predictors for complications were elevated NLR in all flaps (OR 1.5), low SMM in radial forearm flap (OR 2.0), and elevated NLR combined with low SMM in fibula flap surgery (OR 4.3). Patients with solely elevated NLR were at risk for flap-related complications (OR 3.0), severe complications (OR 2.2), and when combined with low SMM for increased length of hospital stays (LOS) (+3.9 days). In early-stage HNC, low SMM (HR 2.3), and combined elevated NLR with low SMM (HR 2.6) were prognostics for decreased overall survival.

CONCLUSIONS

SMM and NLR are predictive for poor outcomes in patients with HNC undergoing microvascular reconstruction.

Immunological Insights into Opioid-Free Anaesthesia in Oncological Surgery: A Scoping Review

PURPOSE OF REVIEW

The influence of opioids on outcomes after cancer surgery when used, or avoided, intraoperatively remains unclear. There is a need to conduct a scoping review to explore the wider context and provide direction for future research. The review will examine the current state of evidence in humans, with a focus on immunological biomarkers and clinically relevant cancer outcomes in trials comparing opioid-free to opioid-based general anaesthesia.

RECENT FINDINGS

There is limited research on this subject area, which is mainly focused on breast cancer. The most frequently evaluated immunological parameter is the neutrophil-to-lymphocyte ratio. Cancer outcomes are mainly focused on recurrence. The central knowledge gap is understanding how the cellular effects of opioids translate into longer-term patient outcomes. The major challenge for future research is accounting for the immunomodulatory effects of a wide range of confounding factors, which have yet to be clarified.

Predictive value of Leukocyte ImmunoTest (LIT™) in cancer patients: a prospective cohort study

Early diagnosis of cancer is crucial to initiate prompt treatment for better patient outcomes. The host immune function and its associated modulators are considered to be potential biomarkers for early cancer diagnosis. Immune and immune-checkpoint biomarkers have been reported to contribute to cancer development, while a high neutrophil-to-lymphocyte ratio has been shown to be associated with poor survival outcomes in a variety of cancers. One hundred sixty-one cancer patients were recruited to take a cost-effective novel Leukocyte ImmuneTest (LIT). LIT was measured to objectively determine the pre-treatment immune status of patients. The correlation between LIT and other conventional diagnostic markers or tumor-related variables was then investigated. Significant correlations between LIT and white blood cell count, smoking status, and tumor stage 4 were found. In addition, the LIT score significantly differentiated between malignant and benign tumors in this study population. Our work raises the possibility to use LIT for general screening surveillance before further costly specialized equipment is applied for cancer diagnosis.

Predictive Value of Neutrophil-Lymphocyte Ratio as a Marker in Antiresorptive Agent-Related Osteonecrosis of the Jaw: A Retrospective Analysis

Antiresorptive agent-related osteonecrosis of the jaw (ARONJ), a multifactorial disease, can drastically affect a patient’s quality of life. Moreover, disease progression to severe acute inflammation can hinder treatment. Therefore, we aimed to investigate the diagnostic value of the neutrophil−lymphocyte ratio (NLR) and platelet−lymphocyte ratio (PLR) in predicting the risk of acute inflammation in patients with ARONJ. In total, 147 patients with ARONJ were enrolled between 1 January 2011 and 31 December 2019. They were divided into two groups according to their baseline NLR (high NLR vs. low NLR) or PLR (high PLR vs. low PLR) to analyze the relationship between NLR and PLR and the outcomes of acute inflammatory events. An optimal NLR cut-off value of 2.83 was identified for hospitalization for an inflammatory event. Logistic regression analysis showed that NLR > 2.83 was associated with an increased risk of hospitalization for an inflammatory event. A PLR cut-off value of 165.2 was identified for hospitalization for an inflammatory event. However, logistic regression analysis showed that PLR > 165.2 was not significantly associated with hospitalization for an inflammatory event. Our study findings suggest that the NLR has diagnostic value in predicting the risk of hospitalization for inflammatory events among patients with ARONJ.

Survival analysis of 80 elderly patients with esophageal squamous cell carcinoma receiving definitive concurrent chemoradiotherapy with S-1

PURPOSE

This single-center retrospective study aimed to observe survival and prognosis of elderly patients with esophageal cancer receiving radical radiotherapy combined with S1 chemotherapy, and to preliminarily explore whether hematologic indicators or inflammatory indicators before radiotherapy are prognostic factors.

MATERIAL AND METHODS

We retrospectively collected data of 80 elderly patients with esophageal cancer who had received radical concurrent chemoradiotherapy from January 2015 to July 2018. The patients were older than 70 years. Radiation therapy was delivered with intensity-modulated irradiation therapy (IMRT) or volumetric modulated arc therapy (VMAT), while the chemotherapy regimen was S1 alone. Toxicities were evaluated in accordance with the criteria of the Radiation Therapy Oncology Group. Baseline hematologic basic nutritional indicators, such as hemoglobin (HGB), albumin (ALB), and prealbumin (PAB), along with inflammatory indicators, such as the ratio of neutrophils to lymphocytes (NLR), the ratio of platelets to lymphocytes (PLR), were collected to preliminarily analyze their relationship with progression and survival.

RESULTS

The median follow-up time was 39 months (range 30-65 months). The median overall survival and progression-free survival times were 24 and 17 months, respectively. The 1-, 2-, and 3-year overall survival rates were 76.5%, 48.1%, and 31.3%, respectively. The 1-, 2-, and 3-year progression-free survival rates were 57.5%, 37.8%, and 29.4%, respectively. T stage, clinical staging, and lesion region were independent prognostic factors for OS. No significant associations with prognosis were observed either for baseline hematologic or for inflammatory indicators (all P>0.05). The rates of esophagitis (grade 2 and above) and hematologic toxicity were 60% and 45%, respectively.

CONCLUSION

Oral S-1 combined with definitive concurrent radiotherapy for elderly patients with esophageal cancer has a significant survival benefit. The toxicities are well tolerated. It seems that prognosis does not correlate with baseline hematologic nutritional indicators and inflammatory indicators.

Geriatric nutritional risk index as a prognostic factor in patients with recurrent pancreatic cancer

The aim of this study is to investigate the prognostic significance of geriatric nutritional risk index (GNRI) at the time of recurrence in patients with recurrent pancreatic cancer, and the relationship between GNRI and skeletal muscle mass for survival outcomes after recurrence. This study enrolled 77 patients who developed postoperative recurrence. The skeletal muscle mass index (SMI) was used in this study. The patients were divided into a high-GNRI group (n = 36) and a low-GNRI group (n = 41) for the GNRI, and were divided into a high-SMI group (n = 38) and a low-SMI group (n = 39) for SMI. The 2-year post-recurrence overall survival of patients in the high-GNRI group was significantly longer than that of patients in the low-GNRI group (P = 0.001). No significant difference for the 2-year post-recurrence OS curves between the high-SMI group and the low-SMI group was observed (P = 0.125). Upon stratifying the patients with high GNRI or low GNRI according to SMI, There was no significant difference in the 2-year post-recurrence OS curves between the patients with both high GNRI and high SMI and the patients with high GNRI and low SMI (P = 0.399). Similarly, There was no significant difference in the 2-year post-recurrence OS curves between the patients with low GNRI and high SMI and the patients with both low GNRI and low SMI (P = 0.256). Multivariate analysis revealed that the GNRI at the time of recurrence was an independent prognostic risk factor in patients with recurrent pancreatic cancer (P = 0.019). The GNRI at the time of recurrence is useful for predicting the prognosis in patients with recurrence pancreatic cancer. Skeletal muscle mass at the time of recurrence is not contributed to predict post-recurrence survival of patients with recurrent pancreatic cancer.

Neutrophil-lymphocyte ratio as a predictor of adverse outcome in patients with community-acquired pneumonia: A systematic review

Background

Community-acquired pneumonia (CAP) is the acute infection of lung tissue in an immunocompetent who acquired it from the community. Its incidence and mortality are significant and require a marker to predict the severity and mortality in these patients. Neutrophil-lymphocyte ratio (NLR) is a simple, cheap, and easy-to-use marker and this study describes its role in predicting the adverse outcome in patients with CAP.

Methods

PubMed, EMBASE, and Google Scholar were used to search for related studies on February 8, 2021. A total of 186 articles were retrieved upon detailed searching in the databases and search engines. After a series of removing duplicate articles, title and abstract screening, and full-text review; nine articles were found eligible and included in the study. The data from each article were collected in MS Excel and the findings were summarized in this manuscript.

Results

The total number of patients analyzed in this systematic review is 3340. The mean age of the patient in the included studies ranged from 61 to 90.4 years. All studies had adverse outcomes as the endpoint of the study, which included in-hospital mortality or intensive care unit (ICU) admission or deterioration from medium and low risk to high risk or 30 days' mortality. The prevalence of endpoint ranged from 5.8% to 44.8%. NLR with a cutoff value of more than 10 was shown to predict mortality compared to C-reactive protein levels, white blood cell count, neutrophil count, lymphocyte level, Pneumonia Severity Index (PSI) level, PSI class, procalcitonin, and CURB-65 (Confusion, Respiratory rate, Blood pressure, 65 years of age and older) in most of the studies.

Conclusion

NLR is a simple, easily measured yet promising marker for predicting outcomes in patients with CAP.

Clinical and biomarker analyses of sintilimab versus chemotherapy as second-line therapy for advanced or metastatic esophageal squamous cell carcinoma: a randomized, open-label phase 2 study (ORIENT-2)

This randomized, open-label, multi-center phase 2 study (NCT03116152) assessed sintilimab, a PD-1 inhibitor, versus chemotherapy in patients with esophageal squamous cell carcinoma after first-line chemotherapy. The primary endpoint was overall survival (OS), while exploratory endpoint was the association of biomarkers with efficacy. The median OS in the sintilimab group was significantly improved compared with the chemotherapy group (median OS 7.2 vs.6.2 months; P = 0.032; HR = 0.70; 95% CI, 0.50-0.97). Incidence of treatment-related adverse events of grade 3-5 was lower with sintilimab than with chemotherapy (20.2 vs. 39.1%). Patients with high T-cell receptor (TCR) clonality and low molecular tumor burden index (mTBI) showed the longest median OS (15.0 months). Patients with NLR < 3 at 6 weeks post-treatment had a significantly prolonged median OS (16.6 months) compared with NLR ≥ 3. The results demonstrate a significant improvement in OS of sintilimab compared to chemotherapy as second-line treatment for advanced or metastatic ESCC.

Overall Survival Prediction of Advanced Cancer Patients by Selection of the Most Significant Baseline Serum Biomarker Combination

Introduction: Consistent association between elevated baseline serum values and C-reactive protein (CRP), cross-linked fibrin degradation products (D-dimer), lactate dehydrogenase (LDH), decreased baseline serum albumin, absolute lymphocyte count to absolute monocyte count ratio (LMR), elevated absolute neutrophil count to absolute lymphocyte count ratio (NLR), elevated platelet count to absolute lymphocyte count ratio (PLR), and between some combinations of these biomarkers and the short overall survival of patients with malignant diseases has already been reported. These biomarkers are independent prognostic factors for cancer. Here, the most significant biomarker combination of these values was searched and studied in real-life advanced cancer patients of a single center.

Methods: The authors retrospectively analyzed the association of the aforementioned biomarkers and their combination and OS of 75 consecutive cancer patients with locally advanced, recurrent, or metastatic diseases. Validated cut-off determination was used.

Results: CRP, albumin, and PLR showed marked association with OS. Cut-off values for significant shorter OS were 30.65 mg/L (p &lt; 0.001), 44.35 g/L (p &lt; 0.001), and 168.20 (p &lt; 0.001), respectively. Based on assessed biomarker cut-offs, four patient groups were created to determine whether biomarker values were out of range (ORV) compared to cut-off: 1) No ORV biomarkers (n = 24; OS = 26.07 months); 2) one ORV biomarker (n = 21; OS = 13.50 months); 3) two ORV biomarkers (n = 20; OS = 7.97 months), and 4) three ORV biomarkers (n = 10; OS = 3.91 months). Significant differences in OS were detected between the groups: For 1. vs. 2. hazard ratio (HR) = 3.0 (95% CI: 1.5–6.2), p = 0.003; for 1. vs. 3. HR = 4.1 (95% CI: 2.0–8.3), p &lt; 0.001; and for 1. vs. 4. HR = 10.2 (95% CI: 4.2–24.6), p &lt; 0.001.

Conclusion: Based on our analysis, we can confirm that the complex monitoring of CRP, albumin, and PLR would provide a good estimation of OS. Large scale prospective studies are warranted to explore this and other useful combinations of prognostic biomarkers and their relationship to the well-established prognostic systems in real-life.
