Analysis of the Fibrinogen and Neutrophil-Lymphocyte Ratio in Esophageal Squamous Cell Carcinoma: A Promising Blood Marker of Tumor Progression and Prognosis

Interleukin-6 as a Predictive Factor of Pathological Response to FLOT Regimen Systemic Treatment in Locally Advanced Gastroesophageal Junction or Gastric Cancer Patients

BACKGROUND

Perioperative treatment is a gold standard in locally advanced gastric cancer or GEJ cancer in the Western population. Unfortunately, the response rate after neoadjuvant chemotherapy (NAC) remains limited. Moreover, there are currently no biomarkers enabling an individual prediction of therapeutic efficacy. The aim of this study was the identification of serum biomarkers of early response to NAC.

METHODS

We conducted this prospective study in the MSCNRIO in Warsaw, Poland. A total of 71 patients and 15 healthy volunteers gave informed consent. Complete blood count, carcinoembryonic antigen (CEA), carcinoma antigen 125 (CA125), carcinoma antigen 19.9 (CA19.9), and fibrinogen (F) were measured at baseline and before every cycle. Circulating tumour cells (CTCs) and interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and interleukin-10 (IL-10) were measured in a pilot group of 40 patients at baseline and before cycle two (C2) and cycle three (C3).

RESULTS

Of all the measured parameters, only the IL-6 serum level was statistically significant. The IL-6 level before C2 of chemotherapy was significantly decreased in the complete pathological response (pCR) vs. the non-pCR group (3.71 pg/mL vs. 7.63 pg/mL, p = 0.004). In all patients with an IL-6 level below 5.0 pg/mL in C2, tumour regression TRG1a/1b according to the Becker classification and ypN0 were detected in postoperative histopathological specimens. The IL-6 level before C1 of chemotherapy was significantly elevated in ypN+ vs. ypN0 (7.69 pg/mL vs. 2.89 pg/mL, p = 0.022).

CONCLUSIONS

The trial showed that an elevated level of IL-6 prior to treatment and C2 might be a predictor of pathological response to NAC.

Prognostic value of the combined preoperative plasma fibrinogen and systemic inflammatory indexes in ESCC patients

The prognostic indexes based on the combination of preoperative fibrinogen and systemic inflammatory indexes may have greater predictive value in esophageal squamous cell carcinoma (ESCC). It was found that the predictive ability of F-NLR was more valuable than other systemic inflammatory indexes. The preoperative F-NLR score was closely related to the TNM stage, and could be used as an important independent prognostic index for patients with ESCC. Then the nomogram model constructed by F-NLR and TNM stage had higher prognostic ability than that of AJCC stage for ESCC patients. Preoperative F-NLR is a new independent prognostic index and a potential marker for treatment response monitoring in patients with ESCC.

Prognostic analysis of the plasma fibrinogen combined with neutrophil-to-lymphocyte ratio in patients with non-small cell lung cancer after radical resection

BACKGROUND

To investigate the correlation between the fibrinogen combined with neutrophil-to-lymphocyte ratio (F-NLR) and the clinicopathologic features of non-small cell lung cancer (NSCLC) patients who underwent radical resection.

METHODS

This study reviewed the medical records of 289 patients with NSCLC who underwent radical resection. The patients were stratified into three groups based on F-NLR as follows: patients with low NLR and fibrinogen were group A, patients with high NLR or fibrinogen were group B, and patients with high NLR and fibrinogen were group C. Receiver operating characteristic curve and Youden index were used to determine the cutoff value of the NLR and fibrinogen. Survival curves were described by Kaplan-Meier method and compared by log-rank test. The univariate and multivariate analyses were performed with the Cox proportional hazard model to identify the prognostic factors.

RESULTS

A value of 3.19 was taken as the optimal cutoff value of NLR in this study. A value of 309 was used as the optimal cutoff value of fibrinogen. Cox multivariate analysis showed that tumor, nodes, metastasis (TNM) stage and F-NLR were independent prognostic factors affecting the survival rate of patients. The first-, third-, and fifth-year survival rates in group A were 99.2%, 96.6%, and 95.0%, respectively. The first-, third-, and fifth-year survival rates in group B were 98.4%, 76.6%, and 63.2%, respectively. The first-, third-, and fifth-year survival rates in group C were 91.3%, 41.1%, and 22.8%, respectively. F-NLR was significantly correlated with overall survival in patients with NSCLC (p < 0.001).

CONCLUSIONS

The F-NLR level is markedly related to the prognosis of patients with NSCLC undergoing radical surgery. Therefore, closer attention should be given to patients with NSCLC with a high F-NLR before surgery to provide postoperative adjuvant therapy.

The prognostic significance of preoperative nutritional/inflammatory markers and clinicopathological features in resectable esophagectomy patients: possibility of nutritional intervention

BACKGROUND

Preoperative inflammatory or nutritional biomarkers and clinicopathological features may be survival predictors in resectable esophageal squamous cell carcinoma.

METHODS

We included 118 patients with resectable squamous esophageal carcinoma (stages I-IV), assessing preoperative CRP- and albumin-based modified Glasgow prognostic score, the modified controlling nutritional status score, C-reactive protein, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, pathologic stage, and tumor location(s), looking for correlation with overall survival and relapse-free survival. Using univariate and Cox analysis, we selected the most reliable prognostic factors.

RESULTS

Five-year overall survival and recurrence-free survival were 54.9% and 48.5%, respectively. C-reactive protein values correlated negatively with hypoalbuminemia (P = 0.0036). On univariate analysis, tumor stage, invasion depth, location, nodal involvement, albumin, and modified Glasgow prognostic score were significant prognostic factors for overall and recurrence-free survival. Preoperative C-reactive protein was prognostic factor for overall survival, but not for relapse-free survival (P = 0.017, 0.063, respectively). The Cox proportional hazards model showed the modified Glasgow prognostic score to be an independent prognostic factor for relapse-free survival and overall survival after using the stepwise variable selection procedure. Cox analysis including clinicopathological factors and modified Glasgow prognostic scores showed that only tumor location(s) and pathologic stage were independent prognostic factors for overall survival and recurrence-free survival.

CONCLUSION

Although the modified Glasgow prognostic score is not superior to pathologic stage and tumor location as a biomarker of preoperative nutrition/inflammation and clinicopathological factors, it remains an important prognostic marker in resectable esophageal cancers. Preoperative decreased inflammatory response and improved nutritional status may contribute to prognosis in patients with esophageal cancer.

Novel prognostic indicator combining inflammatory indicators and tumor markers for gastric cancer

BACKGROUND

Gastric cancer (GC) is one of the most common malignant tumors worldwide, and we hope to identify an economical but practical prognostic indicator. It has been reported that inflammatory indicators and tumor markers are associated with GC progression and are widely used to predict prognosis. However, existing prognostic models do not comprehensively analyze these predictors.

METHODS

This study retrospectively reviewed 893 consecutive patients who underwent curative gastrectomy from January 1, 2012, to December 31, 2015, in the Second Hospital of Anhui Medical University. Prognostic factors predicting overall survival (OS) were analyzed using univariate and multivariate Cox regression analyses. Nomograms including independent prognostic factors were plotted for predicting survival.

RESULTS

Ultimately, 425 patients were enrolled in this study. Multivariate analyses demonstrated that the neutrophil-to-lymphocyte ratio (NLR, total neutrophil count/lymphocyte count × 100%) and CA19-9 were independent prognostic factors for OS (p=0.001, p=0.016). The NLR-CA19-9 score (NCS) is constructed as the combination of the NLR and CA19-9. We defined NLR<2.46 and CA19-9≤37 U/ml as an NCS of 0, NLR≥2.46 or CA19-9>37 U/ml as an NCS 1, and NLR≥2.46 and CA19-9>37 U/ml as an NCS of 2. The results showed that higher NCS was significantly associated with worse clinicopathological characteristics and OS (p<0.05). Multivariate analyses revealed that the NCS was an independent prognostic factor for OS (NCS1: p<0.001, HR=3.172, 95% CI=2.120-4.745; NCS2: p<0.001, HR=3.052, 95% CI=1.928-4.832). Compared with traditional predictive indices, the NCS had the highest AUC for a 12-month survival, a 36-month survival, a 60-month survival, and OS (AUC= 0.654, 0.730, 0.811, 0.803, respectively). The nomogram had a higher Harrell's C-index than the TNM stage alone (0.788 vs. 0.743).

CONCLUSIONS

The NCS provides more accurate predictions of the prognosis of GC patients, and its predictive value is significantly better than that of traditional inflammatory indicators or tumor markers. It is an effective complement to existing GC assessment systems.

Prognostic Impact of Using Combined Plasma Fibrinogen Level and Neutrophil-to-Lymphocyte Ratio in Resectable Non-small Cell Lung Cancer

BACKGROUND

Both plasma fibrinogen level and neutrophil-to-lymphocyte ratio (NLR) are associated with malignant potential in different cancer types. The current study evaluated the use of combined plasma fibrinogen level and NLR (F-NLR) as a prognostic predictor in patients with non-small cell lung cancer (NSCLC).

METHODS

Data collected from 279 patients with resectable NSCLC were retrospectively reviewed. Patients were divided into three groups based on the F-NLR score: score 2, high fibrinogen level (≥350 mg/dL) and high NLR (≥2.5); score 1, either high fibrinogen level or high NLR; and score 0, neither abnormal. Overall survival (OS) and relapse-free survival (RFS) were evaluated using the Kaplan-Meier method and log-rank test. Cox proportional hazard model was used to assess prognostic factors.

RESULTS

Numbers of patients with F-NLR score of 0, 1, and 2 were 122 (43.7%), 105 (37.6%), and 52 (18.6%), respectively. The F-NLR was found to be significantly associated with age, male sex, heavy smoking history, high pT status and pathological stage, and nonadenocarcinoma. Moreover, the OS and RFS significantly differed according to the F-NLR score (P < 0.001, P = 0.003). A multivariate analysis revealed that a high F-NLR score (≥1) was an independent poor prognostic factor for OS (P = 0.027). In subgroup analyses, an adverse prognostic impact of the F-NLR score on OS was identified regardless of nodal involvement or pathological stage.

CONCLUSIONS

The F-NLR score, which is based on histological inflammation and coagulability, could be a potential prognostic indicator in patients with resectable NSCLC.

Prognostic significance of combined score of fibrinogen and neutrophil-lymphocyte ratio for functional outcome in patients with aneurysmal subarachnoid hemorrhage

Objective

To explore the relationship between fibrinogen and neutrophil to lymphocyte ratio (F-NLR) score and functional outcomes after aneurysmal subarachnoid hemorrhage (aSAH).

Method

A retrospective study was conducted that involved all consecutive patients with aSAH admitted to our institution from March 2018 to October 2021. Factors, such as demographics, comorbidities, clinical characteristics, neuroradiological data, and laboratory parameters, were collected from institutional databases. All patients achieved neurological assessment using the modified Rankin Scale (mRS) score 3 months after discharge to clarify the functional outcomes. The results were classified as favorable (mRS score 0–2) and unfavorable (mRS score 3–6). Univariate and multivariable analyses were performed to identify the relevant factors between inflammatory markers and functional outcomes after aSAH. Subsequently, a receiver operating characteristic (ROC) curve analysis was conducted to evaluate the predicting performance of variables. A propensity score match (PSM) was performed to correct imbalances in patients' baseline characteristics.

Results

Finally, 256 patients with aSAH were included in the study cohort. A total of 94 (36.7%) patients had an unfavorable outcome. F-NLR scores were 0 [interquartile range (IQR) 0–1] and 1 (IQR 1–2) in patients with favorable and unfavorable outcomes, respectively (p < 0.001). After adjustment, the F-NLR score on admission remained significantly associated with unfavorable outcomes in patients with aSAH. In the multivariable analysis, the F-NLR score was regarded as an independent risk factor of unfavorable outcomes [odds ratio (OR) 3.113, 95% CI 1.755–5.523, p < 0.001]. In ROC analysis, the optimal cutoff value of the F-NLR score was 0.5 points. Two cohorts (n = 86 in each group) obtained from PSM with low F-NLR scores (0 points) and high F-NLR scores (1–2 points) were used for analysis. A significantly higher unfavorable functional outcome rate was observed in patients with high F-NLR scores (33.7 vs. 9.3%, p < 0.001). The area under the curve (AUC) values of F-NLR scores before and after PSM were 0.767 and 0.712, respectively.

Conclusion

Fibrinogen and neutrophil to lymphocyte ratio score was an independent risk parameter associated with unfavorable functional outcomes at 3 months after aSAH. A higher F-NLR score predicts the occurrence of poor functional outcomes.

Neutrophile-to-lymphocyte, lymphocyte-to-monocyte, and platelet-to-lymphocyte ratios as prognostic and response biomarkers for resectable locally advanced gastric cancer

BACKGROUND

Perioperative fluorouracil plus leucovorin, oxaliplatin, and docetaxel (FLOT) improves prognosis in locally advanced gastric cancer (LAGC). Neutrophil-to-lymphocyte (NLR), lymphocyte-to-monocyte (LMR), and platelet-to-lymphocyte (PLR) ratios are prognostic biomarkers but not predictive factors.

AIM

To assess blood ratios’ (NLR, LMR and PLR) potential predictive response to FLOT and survival outcomes in resectable LAGC patients.

METHODS

This was a multicentric retrospective study investigating the clinical potential of NLR, LMR, and PLR in resectable LAGC patients, treated with at least one preoperative FLOT cycle, from 12 Portuguese hospitals. Means were compared through non-parametric Mann-Whitney tests. Receiver operating characteristic curve analysis defined the cut-off values as: High PLR > 141 for progression and > 144 for mortality; high LMR > 3.56 for T stage regression (TSR). Poisson and Cox regression models the calculated relative risks/hazard ratios, using NLR, pathologic complete response, TSR, and tumor regression grade (TRG) as independent variables, and overall survival (OS) as the dependent variable.

RESULTS

This study included 295 patients (mean age, 63.7 years; 59.7% males). NLR was correlated with survival time (r = 0.143, P = 0.014). PLR was associated with systemic progression during FLOT (P = 0.022) and mortality (P = 0.013), with high PLR patients having a 2.2-times higher risk of progression [95% confidence interval (CI): 0.89-5.26] and 1.5-times higher risk of mortality (95%CI: 0.92-2.55). LMR was associated with TSR, and high LMR patients had a 1.4-times higher risk of achieving TSR (95%CI: 1.01-1.99). OS benefit was found with TSR (P = 0.015) and partial/complete TRG (P < 0.001). Patients without TSR and with no evidence of pathological response had 2.1-times (95%CI: 1.14-3.96) and 2.8-times (95%CI: 1.6-5) higher risk of death.

CONCLUSION

Higher NLR is correlated with longer survival time. High LMR patients have a higher risk of decreasing T stage, whereas high PLR patients have higher odds of progressing under FLOT and dying. Patients with TSR and a pathological response have better OS and lower risk of dying.

Prognostic Significance of the Combined Score of Plasma Fibrinogen and Neutrophil-Lymphocyte Ratio in Patients with Spontaneous Intracerebral Hemorrhage

Background

The combination of plasma fibrinogen and neutrophil to lymphocyte ratio (F-NLR) score is a novel inflammatory marker constituted by peripheral blood fibrinogen concentration and neutrophil to lymphocyte ratio. In the current study, we aim to explore the relationship between admission F-NLR score and intracerebral hemorrhage (ICH) and assess its prognostic predictive ability in ICH patients.

Methods

The original cohort was consecutively recruited from August 2014 to September 2017, and the validation cohort was consecutively recruited between October 2018 and March 2020. The primary outcomes were 3-month functional outcome and 1-month mortality. All statistical analyses were performed using SPSS and R software.

Results

A total of 431 and 251 ICH patients were included in original cohort and validation cohort, respectively. In the original cohort, F-NLR score could independently predict the 3-month functional outcome (adjusted OR 2.013, 95% CI 1.316-3.078, p = 0.001) and 1-month mortality (adjusted OR 3.036, 95% CI 1.965-4.693, p < 0.001). Receiver operation characteristic (ROC) analyses and predictive model comparison indicated that F-NLR score had a stronger predictive ability in the 3-month outcome and 1-month mortality. Validation cohort verified the results.

Conclusion

F-NLR score was an independent indicator for both the 3-month functional outcome and 1-month mortality, and its prognostic predictive ability was superior to fibrinogen and NLR in both the original and the validation cohort.

Prognostic Value of Post First-Line Chemotherapy Glasgow Prognostic Score in Advanced Non-Small Cell Lung Cancer

Background:

The Glasgow prognostic score (GPS) is an established inflammatory prognostic index in cancer patients. Most studies have only measured GPS at baseline (B-GPS). Effective cancer therapy may reduce inflammation, and we investigated whether re-assessing GPS after first-line chemotherapy (E-GPS) provided more prognostic information than B-GPS in a phase III trial of advanced non-squamous non-small cell lung cancer (NSCLC).

Methods:

Glasgow prognostic score was assessed before and after carboplatin/vinorelbine chemotherapy. When assessing GPS, C-reactive protein (CRP) ⩾ 10 mg/L and albumin < 35 mg/L are defined as abnormal values. GPS 0: both values normal, GPS 1: one abnormal value, and GPS 2: both values abnormal.

Results:

Glasgow prognostic score at baseline and E-GPS were available in 138 patients. Median age was 67 years, 51% were women, and 94% had performance status 0-1. B-GPS was not a statistically significant prognostic factor (B-GPS 1 vs 0: hazard ratio [HR] = 1.32, 95% confidence interval [CI] = 0.9-2.0; B-GPS 2 vs 0: HR = 1.46, 95% CI = 0.9-2.3), while E-GPS was (E-GPS 1 vs 0: HR = 1.57, 95% CI = 1.0-2.4; E-GPS 2 vs 0: HR = 2.77, 95% CI = 1.7-4.5). E-GPS was associated with treatment response ( P < .01), whereas B-GPS was not.

Conclusion:

Glasgow prognostic score at baseline after first-line chemotherapy provided more prognostic information than baseline GPS in patients with advanced non-squamous NSCLC and was associated with treatment response.

Neutrophil Extracellular Traps in Digestive Cancers: Warrior or Accomplice

Characterized as a complex of extracellular DNA fibers and granule proteins, neutrophil extracellular traps (NETs) are generated specifically by neutrophils which play a critical role in host defense and immune regulation. NETs have been initially found crucial for neutrophil anti-microbial function. Recent studies suggest that NETs are involved in tumorigenesis and cancer progression. However, the function of NETs in cancer remains unclear, which might be due to the variation of research models and the heterogeneity of cancers. Although most of malignant tumors have similar biological behaviors, significant differences indeed exist in various systems. Malignant tumors of the digestive system cause the most incidence and mortality of cancer worldwide. In this review, we would focus on research developments on NETs in digestive cancers to provide insights on their role in digestive cancer progression and future research directions.

The value of complete blood count for the prognosis analysis of preoperative esophageal squamous cell carcinoma

OBJECTIVE

To investigate the predictive value of preoperative complete blood count for the survival of patients with esophageal squamous cell carcinoma.

METHODS

A total of 1587 patients with pathologically confirmed esophageal squamous cell carcinoma who underwent esophagectomy in the Cancer Hospital Affiliated to Xinjiang Medical University from January 2010 to December 2019 were collected by retrospective study. A total of 359 patients were as the validation cohort from January 2015 to December 2016, and the remaining 1228 patients were as the training cohort. The relevant clinical data were collected by the medical record system, and the patients were followed up by the hospital medical record follow-up system. The follow-up outcome was patient death. The survival time of all patients was obtained. The Cox proportional hazards regression model and nomogram were established to predict the survival prognosis of esophageal squamous cell carcinoma by the index, their cut-off values obtained the training cohort by the ROC curve. The Kaplan-Meier survival curve was established to express the overall survival rate. The 3-year and 5-year calibration curves and C-index were used to determine the accuracy and discrimination of the prognostic model. The decision curve analysis was used to predict the potential of clinical application. Finally, the validation cohort was used to verify the results of the training cohort.

RESULTS

The cut-off values of NLR, NMR, LMR, RDW and PDW in complete blood count of the training cohort were 3.29, 12.77, 2.95, 15.05 and 13.65%, respectively. All indicators were divided into high and low groups according to cut-off values. Univariate Cox regression analysis model showed that age (≥ 60), NLR (≥3.29), LMR (< 2.95), RDW (≥15.05%) and PDW (≥13.65%) were risk factors for the prognosis of esophageal squamous cell carcinoma; multivariate Cox regression analysis model showed that age (≥ 60), NLR (≥3.29) and LMR (< 2.95) were independent risk factors for esophageal squamous cell carcinoma. Kaplan-Meier curve indicated that age <  60, NLR < 3.52 and LMR ≥ 2.95 groups had higher overall survival (p <  0.05). The 3-year calibration curve indicated that its predictive probability overestimate the actual probability. 5-year calibration curve indicated that its predictive probability was consistent with the actual probability. 5 c-index was 0.730 and 0.737, respectively, indicating that the prognostic model had high accuracy and discrimination. The decision curve analysis indicated good potential for clinical application. The validation cohort also proved the validity of the prognostic model.

CONCLUSION

NLR and LMR results in complete blood count results can be used to predict the survival prognosis of patients with preoperative esophageal squamous cell carcinoma.

Combined score of C-reactive protein level and neutrophil-to-lymphocyte ratio: A novel marker in distinguishing children with exacerbated asthma

Background

Both C-reactive protein (CRP) level and neutrophil-to-lymphocyte ratio (NLR) are commonly elevated in patients with asthma. It is necessary to develop a novel marker, the combined score of CRP level and NLR (C-NLR score) based on cutoff points of CRP and NLR, and apply it in asthma diagnosis. The aim of this study was to explore whether C-NLR could distinguish children with exacerbated asthma.

Methods

Children suffering from exacerbated asthma were regarded as the asthmatic group (n = 86), which was divided into three groups: mild (n = 54), moderate (n = 17), and severe (n = 15). The control group consisted of children without any allergic disease and infection (n = 38). To compare CRP level and NLR between the asthmatic group and control group, a receiver-operating characteristic curve was constructed to determine area under the curve (AUC) and optimal cutoff point. Thereafter, the C-NLR score was classified as follows: C-NLR score of 2 with an elevated CRP level and high NLR, a C-NLR score of 1 with one of these abnormalities, and a C-NLR score of 0 with a normal CRP level and low NLR. The C-NLR score was then compared among different asthma groups.

Results

In the control group, the CRP level and NLR were 1.9 (0.5–2.6) mg/L and 1.01 (0.69–1.31), respectively. In the asthmatic group, the CRP level and NLR were 7.3 (3.2–14.2) mg/L and 3.08 (1.73–5.34), respectively, which were higher than those in the control group (p < 0.001 for CRP and p < 0.001 for NLR). The AUC of CRP was 0.86, and the optimal cutoff point was 3.6 mg/L. The AUC of NLR was 0.86, and the optimal cutoff point was 1.72. The AUC of the C-NLR score was 0.94, and the optimal cutoff point was 1.

Conclusions

C-NLR, a novel inflammatory marker, was applied here for the exacerbated asthma for the first time. Our study has shown C-NLR is a promising marker to distinguish children with exacerbated asthma from healthy children.

Prognostic role of neutrophil-to-lymphocyte ratio (NLR) in urological tumors: an umbrella review of evidence from systematic reviews and meta-analyses

BACKGROUND

Neutrophil-to-lymphocyte ratio (NLR) has been studied as a biomarker for cancer prognosis, predicting survival in many tumors. The aim of this umbrella review was to combine the results from all systematic reviews and meta-analyses related to the prognostic role of the NLR in patients with urological tumors.

METHODS

A PubMed, Scopus, Embase and Cochrane search was undergone from inception through September 2020 for systematic reviews and meta-analyses investigating the prognostic value of NLR in urological tumors, subdivided into prostate cancer, renal cell carcinoma, urothelial bladder and upper tract carcinomas PROSPERO (CRD42020216310).

RESULTS

The results have shown, with a high level of evidence, that an elevated NLR predicts worse overall survival (OS), progression-free survival (PFS) and relapse-free survival (RFS) in prostate cancer, worse OS, PFS and RFS in renal cell carcinoma, worse OS, PFS, RFS and cancer-specific survival (CSS) in muscle invasive bladder cancer, worse PFS and RFS in non-muscle invasive bladder cancer, and worse OS, PFS, RFS and CSS in urothelial upper tract carcinoma.

CONCLUSION

NLR has a significant prognostic value in urological tumors and should be included in prognostic scores of these cancers.

Haematologic indices and disease activity index in primary Sjogren's syndrome

BACKGROUND

The present study was conducted to investigate the association between haematologic indices, neutrophil/lymphocyte ratio (NLR), mean platelet volume (MPV), platelet/lymphocyte ratio (PLR), disease activation, organ involvement, and inflammatory markers in the SS.

METHODS

The study was conducted with newly diagnosed and treatment-naive 41 primary SS patients who met ACR-2012 criteria and 96 healthy volunteers. Blood tests obtained before treatment were evaluated. Lymphocyte, neutrophil and platelet counts, mean corpuscular volume (MCV), platelet distribution width (PDW), plateletcrit (PCT), haematocrit (HCT), MPV, white blood cell count (WBC) values were harvested from CBC of the subjects and NLR, PLR were calculated over these values. The values were compared between groups and correlation with EULAR SS disease activity index (ESSDAI) was evaluated.

RESULTS

The study included a total of 41 patients with a mean age of 40.73 ± 12.0 years and 96 healthy subjects with a mean age of 40.0 ± 9.2 years. In inter-group comparisons, lymphocyte, platelet counts, and MPV values were significantly lower in the SS group compared with the control group (P < .01), and NLR was significantly higher in the SS group (P = .026). The mean ESSDAI scores in SS patients were 5.65 ± 0.86 SE. These scores were significantly higher in patients with neurological involvement. There was a positive correlation between ESSDAI and PLR.

CONCLUSION

NLR, PLR, and MPV may be used as indicators or with activity index in SS. ESSDAI scores were found to be high in patients with neurological involvement, and it was also found to be correlated with PLR.

Prognostic Value of the Hemoglobin/Red Cell Distribution Width Ratio in Resected Lung Adenocarcinoma

BACKGROUND

The ratio of hemoglobin to red cell distribution width (HRR) has been described as an effective prognostic factor in several types of cancer. The aim of this study was to investigate the prognostic role of preoperative HRR in resected-lung-adenocarcinoma patients.

METHODS

We enrolled 342 consecutive patients. Age, sex, surgical resection, adjuvant treatments, pathological stage, preoperative hemoglobin, red cell distribution width, and their ratio were recorded for each patient.

RESULTS

Mean age was 66 years (SD: 9.0). There were 163 females (47.1%); 169 patients (49.4%) had tumors at stage I, 71 (20.8%) at stage II, and 102 (29.8%) at stage III. In total, 318 patients (93.0%) underwent lobectomy, and 24 (7.0%) pneumonectomy. Disease-free survival multivariable analysis disclosed an increased hazard ratio (HR) of relapse for preoperative HRR lower than 1.01 (HR = 2.20, 95%CI: (1.30-3.72), p = 0.004), as well as for N1 single-node (HR = 2.55, 95%CI: (1.33-4.90), p = 0.005) and multiple-level lymph node involvement compared to N0 for both N1 (HR = 9.16, 95%CI:(3.65-23.0), p < 0.001) and N2 (HR = 10.5, 95%CI:(3.44-32.2, p < 0.001).

CONCLUSION

Pre-operative HRR is an effective prognostic factor of disease-free survival in resected-lung-adenocarcinoma patients, together with the level of pathologic node involvement.

The Prognostic Significance of Combined Pretreatment Fibrinogen and Neutrophil-Lymphocyte Ratio in Various Cancers: A Systematic Review and Meta-Analysis

Purpose

The prognostic value of a new scoring system, termed F-NLR, that combines pretreatment fibrinogen level with neutrophil-lymphocyte ratio has been evaluated in various cancers. However, the results are controversial. The purpose of this study was to comprehensively analyze the prognostic value of F-NLR score in patients with cancers.

Methods

An integrated search of relevant studies was conducted by screening the PubMed and Embase databases. Pooled hazard ratios, with 95% confidence intervals (CIs), for overall survival (OS) and disease-free survival (DFS)/progression-free survival (PFS) were calculated to estimate the prognostic significance of F-NLR score in patients with various tumors. A random effects model was used for comprehensive analysis, and subgroup and meta-regression analyses were used to explore sources of heterogeneity.

Results

Thirteen articles reporting data from of 4747 patients were included in the study. Pooled analysis revealed that high F-NLR score was significantly associated with poor OS (HR = 1.77; 95% CI, 1.51–2.08) and poor DFS/PFS (HR = 1.63; 95% CI, 1.30–2.05). Subgroup and meta-regression analyses did not alter the prognostic role of F-NLR score in OS and DFS/PFS.

Conclusions

Increased F-NLR score is significantly associated with poor prognosis in patients with cancers and can serve as an effective prognostic indicator.

Glasgow prognostic score is a better predictor of the long-term survival in patients with gastric cancer, compared to the modified Glasgow prognostic score or high-sensitivity modified Glasgow prognostic score

Background: Inflammation influences cancer progression by increasing catabolism and impairing nutrient absorption. We compared the prognostic ability of three inflammation-based prognostic scoring systems—the Glasgow prognostic score (GPS), modified GPS (mGPS), and high-sensitivity mGPS (HS-mGPS)—in gastric cancer patients.

Materials and Methods: We retrospectively examined 434 curatively resected gastric cancer patients to evaluate the prognostic ability of scoring systems for overall survival (OS) and cancer-specific survival (CSS).

Results: OS analysis identified the following independent prognostic factors: GPS model: pathological stage (pStage, p < 0.001), carcinoembryonic antigen (CEA, p = 0.004), and GPS 1 (hazard ratio [HR], 1.929; 95% confidence interval [CI], 1.152-3.228; p = 0.013); mGPS model: body mass index (BMI, p = 0.027), pStage (p < 0.001), and CEA (p < 0.001); HS-mGPS model: BMI (p = 0.029), pStage (p < 0.001), and CEA (p = 0.003). mGPS and HS-mGPS were not independent prognostic factors for OS. CSS analysis of the GPS model identified pStage (p < 0.001), CEA (p = 0.015), and GPS 1 (HR; 2.095, 95% CI; 1.025–4.283; p = 0.043) and 2 (HR, 2.812; 95% CI, 1.111–7.116; p = 0.029) as independent prognostic factors; however, mGPS and HS-mGPS were not independent prognostic factors for CSS. Log-rank tests demonstrated significant differences in OS among patients with GPS 0 vs. 1 (p < 0.001) and 0 vs. 2 (p < 0.001) and in CSS among the three GPS (0 vs. 1; p = 0.005, 0 vs. 2; p < 0.001, 1 vs. 2; p = 0.009).

Conclusions: GPS most reliably predicts long-term survival of gastric cancer patients.

Combination of preoperative fibrinogen concentration and neutrophil-to-lymphocyte ratio for prediction of the prognosis of patients with resectable breast cancer

Previous studies have demonstrated that the combination of high preoperative fibrinogen levels and high neutrophil-to-lymphocyte ratio (NLR) is associated with poor outcomes in various types of cancer. The present study assessed the prognostic value of a scoring system based on the combination of fibrinogen concentration and neutrophil-to-lymphocyte ratio (F-NLR) in untreated patients with resectable breast cancer (BC). The present study retrospectively analyzed 906 patients who received surgery for resectable BC. Univariate and multivariate analyses were performed to explore the association between the F-NLR score and survival status. The cut-off values for fibrinogen and NLR determined via receiver operating characteristic curve analysis were 3.21 g/l and 2.20, respectively. On the basis of these cut-off values, the whole cohort was divided into three groups according to their F-NLR score: Score 2, fibrinogen ≥3.21 g/l and NLR ≥2.20; score 1, fibrinogen ≥3.21 g/l or NLR ≥2.20; and score 0, fibrinogen <3.21 g/l and NLR <2.20. The F-NLR score was significantly associated with age (≤50 years vs. >50 years; P<0.001), tumor size (≤2 cm vs. >2 cm; P=0.001), lymph node status (P=0.029), TNM stage (I vs. II vs. III; P=0.002) and lymphovascular invasion (P<0.001). The 5-year disease-free survival (DFS) rates in the patients with F-NLR scores of 0, 1 and 2 were 95.7, 87.5 and 74.0%, respectively (P<0.001), and the 5-year overall survival (OS) rates were 97.8, 90.9 and 79.9%, respectively (P<0.001). Furthermore, multivariate analysis demonstrated that the F-NLR score independently predicted DFS [hazard ratio (HR), 2.279; 95% CI, 1.758-2.954; P<0.001] and OS (HR, 2.414; 95% CI, 1.738-3.353; P<0.001). In conclusion, the preoperative F-NLR score was an independent prognostic indicator for untreated patients with resectable BC.

Prognostic Value of the Combined Index of Plasma Fibrinogen and the Neutrophil-Lymphocyte Ratio in Gastric Cancer

BACKGROUND

It has been reported that both fibrinogen and the neutrophil-lymphocyte ratio (NLR) are related to the degree of malignancy in various types of cancer. This study compared the combined index of fibrinogen and NLR (F-NLR) with NLR alone for predicting the prognosis of patients with resectable gastric cancer.

METHODS

We collected data on 666 patients with resectable gastric cancer. Patients were divided into three F-NLR score groups based on the following criteria: score 2, both hyperfibrinogenemia (≥350 mg/dl) and high NLR (≥2.5); score 1, either hyperfibrinogenemia or high NLR; and score 0, neither abnormality. The association between prognosis and NLR alone or F-NLR was evaluated using the Kaplan-Meier method and Cox multivariate analysis.

RESULTS

The high-NLR group had significantly worse overall survival (OS) than the low-NLR group (hazard ratio 1.62; 95% confidence interval [CI] 1.07-2.45; log-rank P = 0.022), but there was no significant difference between the high- and low-NLR groups after adjusting for the fibrinogen level. F-NLR groups showed significantly different OS (log-rank P < 0.001) and recurrence-free survival (log-rank P < 0.001). The 5-year OS rate for the groups with F-NLR scores of 2, 1, and 0 was 72.6%, 81.4%, and 90.4%, respectively. A Cox multivariate analysis of OS revealed that a high F-NLR score (1 or 2) was an independent prognostic factor (P = 0.007).

CONCLUSIONS

F-NLR was an independent prognostic factor in patients with gastric cancer and a more useful prognostic indicator than NLR alone.

Predicting Individual Prognosis and Grade of Patients with Glioma Based on Preoperative Eosinophil and Neutrophil-to-Lymphocyte Ratio

Purpose

Eosinophils are proven to play a role in the prognosis of some malignant-tumors. The prognostic value of eosinophils in glioma patients is, however, scarcely reported. The authors of this article have designed a novel prognostic indicator based on eosinophils and the neutrophil-to-lymphocyte ratio (NLR), named ENS, to predict the survival of patients with glioma.

Methods

A retrospective study was conducted on 217 glioma patients. The cut-off values for eosinophil, NLR, and other clinical variables were determined by the receiver operating characteristic (ROC) curve analysis. Patients with both low eosinophil count (<0.08 ×10⁹/L) and high NLR (≥1.70) were given a score of 2. Those with one or neither got a score of 1 or 0, respectively. The nomogram was based on ENS and several other clinical variables, its performance was determined by the concordance index (c-index).

Results

Our results showed that ENS is an independent prognostic indicator for overall survival (OS). The three-year OS rates for low-grade glioma patients (LGGs) were 84.0%, 69.0%, and 46.4% for ENS=0, ENS=1, and ENS=2, respectively (P=0.014). The three-year OS incidence for LGGs stratified into eosinophils count ≥0.08×109/L and<0.08×109/L subgroups were 88.1% and 80.0%, respectively (P=0.043). ENS was positively correlated with glioma grade (r=0.311, P<0.001). The c-index for OS prognosis was 0.80 using this nomogram in LGGs.

Conclusion

Preoperative ENS can predict OS to some extent for LGGs and can increase prognostic accuracy for individual OS in LGGs postoperatively when incorporating other clinical variables compose a nomogram.

High Preoperative Fibrinogen and Systemic Inflammation Response Index (F-SIRI) Predict Unfavorable Survival of Resectable Gastric Cancer Patients

Purpose

This study was to investigate the prognostic significance of the preoperative fibrinogen and systemic inflammation response index (F-SIRI) in a Chinese cohort of resectable gastric cancer.

Materials and Methods

Baseline characteristics, preoperative fibrinogen levels and peripheral neutrophil, monocyte, and lymphocyte counts were retrospectively reviewed in 240 patients who underwent radical gastrectomy. The optimal cut-off values for fibrinogen and SIRI were defined as 4.0 g/L and 1.2. Then patients with hyperfibrinogenemia (≥4.0 g/L) and high SIRI (≥1.2) were assigned with an F-SIRI of 2 (both of these hematological abnormalities), 1 (one of these abnormalities), and 0 (neither abnormality), respectively. The prognostic value was examined by univariate and multivariate survival analysis.

Results

Preoperative F-SIRI was significantly correlated with tumor size, fibrinogen level, and adjuvant chemotherapy. Whereas there was no significant difference in age, gender, tumor location or other characteristics between groups. In addition, high preoperative F-SIRI was significantly associated with worse disease-free survival (DFS) (hazard ratio [HR], 2.299; 95% confidence interval [CI], 1.482–3.566; P<0.001) and overall survival (OS) (HR, 2.461; 95% CI, 1.584–3.824; P<0.001) by univariate survival analysis. Moreover, it remained an independent predictor for impaired DFS (HR, 2.023; 95% CI, 1.273–3.215; P=0.003) and OS (HR, 2.341; 95% CI, 1.480–3.705; P<0.001) in multivariate Cox regression analysis.

Conclusions

Preoperative F-SIRI could serve as a significantly prognostic marker for long-term survival in Chinese patients who underwent radical gastrectomy.

Prognostic Value of Neutrophil-Lymphocyte Ratio in Cardiogenic Shock: A Cohort Study

BACKGROUND Inflammation plays an important part in the pathogenesis of cardiogenic shock (CGS). Whether the neutrophil-lymphocyte ratio (NLR), an integrated biomarker of inflammation, is associated with the outcome of CGS patients remains unknown. This retrospective cohort study was performed to identify the utility of using NLR among patients with CGS. MATERIAL AND METHODS Data were extracted from the MIMIC database. We applied smooth curve fitting to define the NLR cutoff values. The primary outcome was 30-day mortality. Cox proportional hazards models, subgroup analysis, and receiver operator characteristic (ROC) curve analysis were performed. RESULTS A total of 1470 CGS patients were extracted, among which 801 (54.5%) were men. The mean age of the population was 70.37 years. An inverse U-shaped relationship was observed between NLR and mortality in CGS patients, with the highest risk being at values ranging from 9.4 to 15. For the primary outcome of 30-day mortality, the adjusted HR (95% CI) values of the middle tertile (NLR 9.4-15) and the upper tertile (NLR >15) were 1.47 (1.14, 1.88) and 1.22 (0.94, 1.57) compared with the reference of lower tertile (NLR <9.4). ROC curve analysis showed that NLR had a more sensitive prognostic value in predicting 30-day mortality of CGS than the neutrophil or lymphocyte percentage alone (0.660 vs. 0.540, 0.549). CONCLUSIONS An inverse U-shaped curve was presented between NLR and the mortality of CGS. NLR seemed to be a readily available and independent prognostic biomarker for patients with CGS. The prognostic value of NLR was more sensitive than the neutrophil or lymphocyte percentage alone, but not as good as SOFA or SAPSII score.

The prevalence of cancer associated systemic inflammation: Implications of prognostic studies using the Glasgow Prognostic Score

The prognostic importance of SIR in patients with cancer is widely recognised. More recently it has become clear that the systemic inflammatory response is an important etiologic factor in the development of cancer cachexia. Two recent meta-analysis carried out in 2017 and 2018 were interrogated and the number of patients with specific cancer types were identified. The percentage of patients with operable cancer (n>28,000) who were systemically inflamed varied from 21% to 38%. The percentage of patients with inoperable cancer (n>12,000) who were systemically inflamed varied from 29% to 79%. Overall, the percentage of patients (n>40,000) who were systemically inflamed varied from 28% to 63% according to tumour type. The most commonly studied cancer was colorectal cancer (n∼10,000 patients) and 40% were systemically inflamed.

Preoperative elevated plasma fibrinogen level predicts tumor recurrence and poor prognosis in patients with hepatocellular carcinoma

Background

Elevated plasma fibrinogen has been reported to be associated with poor prognosis in several cancers. The aim of present study was to investigate the prognostic value of preoperative plasma fibrinogen in hepatocellular carcinoma (HCC) patients.

Methods

Data were collected retrospectively from 302 HCC patients who received hepatectomy. The association between fibrinogen and clinicopathological characteristics was evaluated. Both univariate and multivariate analyses were performed to identify prognostic factors for disease-free survival (DFS) and overall survival (OS). And accordingly, the nomograms were constructed.

Results

Elevated plasma fibrinogen (>4 g/L) was correlated with larger tumor diameter, the presence of vascular invasion, lower MELD score, higher NLR, advanced Barcelona Clinic Liver Cancer stage and poor-moderate pathological differentiation. On multivariate analysis, the elevated plasma fibrinogen was found independently associated with poor DFS (HR =1.575, P=0.024) and OS (HR =2.051, P=0.025). And the nomograms including fibrinogen were constructed to predict DFS and OS for HCC patients. Both DFS and OS in patients with plasma fibrinogen >4 g/L were significantly lower than those with fibrinogen ≤4 g/L (1-, 3-, 5-year DFS: 34.2%, 19.5% and 0.0% vs. 60.4%, 34.2% and 30.2%; 1-, 3-, 5-year OS: 83.4%, 62.7% and 48.8% vs. 95.4%, 84.3% and 75.8%, both P<0.001). Besides, subgroup analyses also showed the prognostic values of fibrinogen in HCC patients with/without cirrhosis or high AFP levels, and in those with single tumor and BCLC 0-A stage.

Conclusions

Preoperative elevated plasma fibrinogen was an independent prognostic factor associated with poor prognosis in HCC patients receiving liver resection.

The prognostic value of modified Glasgow prognostic score in patients with esophageal squamous cell cancer: a Meta-analysis

Objective: To evaluate the prognostic value of modified Glasgow prognostic score (mGPS) asssessed prior to anticancer treatment in patients with esophageal squamous cell cancer (ESCC).Methods: A comprehensive search through PubMed, EMBASE, Web of Science and The Cochrane Library databases was performed to identify potential studies exploring the prognostic value of baseline mGPS in patients with ESCC. We combined the hazard ratios (HRs) with 95% confidence intervals (CIs) to assess the association of mGPS with overall survival (OS).Results: A total of 10 studies including 3415 patients were analyzed and all patients were from Japan or China. A significant correlation between elevated mGPS and poor OS (HR = 1.66, 95% CI: 1.14-2.41, P = 0.008) was observed. Subgroup analyses suggested that the country and therapy method may affect the effect of mGPS on predicting OS in ESCC and patients with mGPS 1 or two had poorer OS compared with those with mGPS 0 (HR = 2.91, 95% CI: 1.74-4.87, P<0.001; HR = 2.39, 95% CI: 1.44-3.97, P = 0.001).Conclusions: Baseline mGPS might serve as a promising indicator for the OS in Chinese and Japanese patients with ESCC. More well-designed prospective studies with large samples are needed to verify our findings.

Differential Expression and Diagnostic Significance of Pre-Albumin, Fibrinogen Combined with D-Dimer in AFP-Negative Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is one of the most malignant cancers with high morbidity and mortality. Nowadays, AFP-negative hepatocellular carcinoma (AFP-NHCC) has been found in many HCC patients and AFP analysis can't be used to screen HCC in these cases. In this study, we have examined the expression patterns of pre-albumin (PA), fibrinogen, D-Dimer and their clinical significance in AFP-NHCC. We recruited 214 AFP-NHCC patients and 210 controls in the study. PA, fibrinogen and D-Dimer levels were detected by turbidimetry, clauss and immunoturbidimetry methods, respectively. Serum PA levels were significantly lower in AFP-NHCC (84.5 ± 24.7 mg/L) than that in the controls (240.6 ± 59.4 mg/L, P < 0.05). For plasma fibrinogen levels, there was no difference between the controls (2.9 ± 0.7 g/L) and AFP-NHCC (2.5 ± 0.7 g/L). Compared with AFP-NHCC (0.8 ± 0.2 mg/L), plasma D-Dimer levels were significantly lower in controls (0.1 ± 0.0 mg/L, P < 0.05). The levels of PA, fibrinogen and D-Dimer were significantly correlated with differentiation (P < 0.01), and the PA and D-Dimer values were correlated with TNM stage (P < 0.05). Moreover, PA levels were correlated with tumor size (P = 0.034). Receiver operating characteristic curve (ROC) analyses elaborated that combination of PA, fibrinogen and D-Dimer possessed a higher sensitivity (93.4%) for differentiating AFP-NHCC from the controls, but the diagnostic specificity was reduced due to the combination of fibrinogen. After adjusting for all significant outcome predictors of the univariate logistic regression analysis, low levels of PA and high levels of D-Dimer were remained independent unfavorable outcome predictors (P < 0.05). Our data suggested that the expression levels of PA, fibrinogen and D-Dimer played critical roles in AFP-NHCC tumorigenesis. Moreover, PA and D-Dimer might be considered as potential diagnostic indicators in AFP-NHCC.

Combined neutrophil-lymphocyte ratio and platelet-lymphocyte ratio predicts chemotherapy response and prognosis in patients with advanced gastric cancer

Background

The neutrophil–lymphocyte ratio (NLR) and platelet–lymphocyte ratio (PLR) are representative blood markers of systemic inflammatory responses. However, the clinical significance of the combination of these markers is unclear. This study aimed to investigate the NLR and PLR in patients with advanced gastric cancer treated with chemotherapy and assess the clinical utility of a new blood score combining the NLR and PLR (NLR-PLR score) as a predictor of tumor response and prognosis.

Methods

We retrospectively analyzed 175 patients with gastric cancer receiving chemotherapy or chemoradiotherapy. These patients were categorized into progressive disease (PD) and non-PD groups according to tumor response. The NLR and PLR before treatment were examined, and the cut-off values were determined. The NLR-PLR score ranged from 0 to 2 as follows: score of 2, high NLR (> 2.461) and high PLR (> 248.4); score of 1, either high NLR or high PLR; score of 0, neither high NLR nor high PLR.

Results

With regard to tumor response, 64 and 111 patients had PD and non-PD, respectively. The NLR-PLR score was significantly higher in patients with PD than in those with non-PD (p = 0.0009). The prognosis was significantly poorer in patients with a higher NLR-PLR score than in those with a lower NLR-PLR score (p <  0.0001). Multivariate analysis demonstrated that the NLR-PLR score was an independent prognostic factor for prediction of overall survival (p = 0.0392).

Conclusion

Low-cost stratification according to the NLR-PLR score might be a promising approach for predicting tumor response and prognosis in patients with advanced gastric cancer.

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

A high preoperative neutrophil-lymphocyte ratio (NLR) has been shown in several studies as a predictor of worse survival in many solid neoplasms, including esophageal cancer, but its impact remains unclear. The goal of this systematic review was to gain all the evidence about NLR in order to analyse its potential in predicting survival in esophageal cancer. Therefore, we conducted a systematic literature search of all relevant studies reporting data on NLR as prognostic marker in esophageal cancer patients. We considered overall survival (OS) as primary outcome, disease-free survival (DFS) and progression-free survival (PFS) as secondary outcomes. We included studies with a directly or indirectly available hazard ratio (HR), furthermore we used both fixed effect model and random effect model depending on heterogeneity. We included a total of 20 studies, published between 2011 and 2017, consisting of 6,457 patients. The NLR cut-off value ranges from 1.7 to 5. The HR for OS of all included studies was 1.60. The HR for DFS and PFS was 1.75 and 1.66 respectively. The survival sub-analysis about tumor characteristics, treatment modality, blood sample timing also confirmed NLR prognostic relevance with statistically significant results. The meta-analysis showed that high preoperative NLR is associated with worse survival in esophageal cancer, as shown in several solid tumors, but its use in the clinical practice is still underestimated. High-quality studies are needed to assess the most effective cut-off in survival prognostication and NLR relevance on postoperative complications.

A novel preoperative plasma indicator to predict prognoses for patients with esophageal squamous cell carcinoma after radical esophagectomy: fibrinogen-to-lymphocyte ratio

Purpose: The inflammatory microenvironment and hemostatic system are involved in several stages of tumor progression. The aim of this study was to assess the prognostic effect of fibrinogen-to-lymphocyte ratio (FLR) in esophageal squamous cell carcinoma (ESCC) patients who underwent radical esophagectomy. Patients and methods: We retrospectively reviewed 673 consecutive patients with ESCC who underwent radical esophagectomy from January 2009 to December 2012 at a major cancer hospital in Guangzhou, southern China. The cutoff points were defined by the X-tile software. The prognostic value of FLR for overall survival (OS), disease-free survival (DFS), and first-year mortality after surgery were analyzed using Cox proportional hazard regression model and logistic regression model. Survival was estimated by the Kaplan-Meier estimator and compared using the log-rank test. Results: The optimal cutoff point of FLR was 3.03. Compared with the FLR-low (≤3.03) group, the FLR-high (>3.03) group included older patients (χ²=7.267, P=0.007), showed higher postoperative overall morbidity (24.7% vs 14.8%, χ²=5.414, P=0.020) and tended to die within one year (23.5% vs 10.9%, χ²=10.871, P=0.001). The FLR-high group showed significant lower 5-year OS rates (41.2% vs 53.7%, log-rank=6.827, P=0.009) and 5-year DFS rates (35.3% vs 48.0%, log-rank=5.954, P=0.015) than the FLR-low group. Multivariate analyses suggested that high FLR was an independent negative predictor of OS (HR: 1.448, 95%CI: 1.073-1.952, P=0.015), DFS (HR: 1.445, 95%CI: 1.084-1.925, P=0.012) and first-year mortality (HR: 2.123, 95%CI: 1.157-3.898, P=0.015). Conclusion: The preoperative FLR level could be used as a simple, noninvasive, inexpensive, and potentially effective indicator to evaluate the prognosis of ESCC patients following radical esophagectomy.

Inflammation-nutrition score predicts prognosis of patients with resectable hepatocellular carcinoma

BACKGROUND

Various inflammation-based prognostic scores have been associated with poor survival in patients with hepatocellular carcinoma (HCC).

METHODS

Data were collected retrospectively from 674 HCC patients who underwent curative resection. The correlation between INS (inflammation-nutrition score), BCLC (Barcelona Clinic Liver Cancer) stage and inflammatory indices and overall survival (OS) and disease free survival (DFS) was examined.

RESULTS

An elevated INS was associated with both tumor and host clinical characteristics. The combination of INS and BCLC stage stratifies OS and DFS from 80% and 65% (INS = 0, stage A) to 0% (INS = 2, stage C). Univariate and multivariate analyses revealed that the INS was an independent predictor for OS and DFS, and was superior to inflammation-based scores. In addition, INS was demonstrated to be a prognostic factor for patients with early stage and had a higher AUC value in comparison with inflammation scores.

CONCLUSION

This study demonstrates that the INS is an independent marker of poor prognosis in patients with resectable HCC, especially for those with early stage, and it provides complimentary prognostic information to BCLC stage, and may aid in treatment strategy.

High preoperative plasma fibrinogen and serum albumin score is associated with poor survival in operable esophageal squamous cell carcinoma

This study was performed to investigate the prognostic significance of a cumulative score based on the preoperative plasma fibrinogen and serum albumin (FA score) in operable esophageal squamous cell carcinoma (ESCC). Clinicopathologic characteristics, preoperative fibrinogen, and albumin concentrations were retrospectively reviewed in patients who underwent transthoracic esophagectomy. The optimal cutoff value was defined as 4.0 g/L for fibrinogen according to previous studies and as 41.0 g/L for albumin for the lower quartile. Subjects with elevated fibrinogen and decreased albumin levels were allocated a score of 2, those with only one of these two abnormalities were assigned a score of 1, and those with neither of the abnormalities were allocated a score of 0. The preoperative FA score was significantly associated with tumor length, depth of invasion, lymph node involvement, tumor-node-metastasis (TNM) stage, and the modified Glasgow Prognostic Score (mGPS). No significant differences in age, gender, tumor location, degree of differentiation, smoking or alcohol consumption were found between groups. Univariate survival analysis revealed that high preoperative FA score (1/2) was significantly associated with unfavorable disease-free survival (DFS) [hazard ratio (HR), 1.675; 95% confidence interval (CI), 1.278-2.195; P < 0.001] and overall survival (OS) (HR, 1.685; 95% CI, 1.268-2.239; P < 0.001). Furthermore, it remained an independent prognostic indicator for both DFS (HR, 1.394; 95% CI, 1.035-1.879; P = 0.029) and OS (HR, 1.369; 95% CI, 1.010-1.878; P = 0.048) in multivariable Cox regression analysis. A high preoperative FA score could significantly predict impaired long-term survival for ESCC patients who underwent transthoracic esophagectomy.

Prognostic significance of the combination of preoperative fibrinogen and the neutrophil-lymphocyte ratio in patients with non-small cell lung cancer following surgical resection

The purpose of the present study was to evaluate the prognostic value of preoperative coagulation factor levels (including fibrinogen and D-dimer) and inflammatory indicators in patients with non-small cell lung cancer (NSCLC). The medical records of 456 patients with NSCLC who had undergone curative resection were retrospectively analysed. The recommended cut-off values for preoperative fibrinogen, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio and lymphocyte-monocyte ratio were determined using receiver operating characteristic curve analyses. The associations between preoperative fibrinogen or D-dimer levels and clinicopathological variables were analysed using the χ² test. Univariate Kaplan-Meier analysis and a multivariate Cox proportional hazards model were applied to identify which prognostic variables were significantly associated with overall survival (OS) rates. Multivariate analyses revealed that lymph node metastasis (P<0.001), preoperative fibrinogen (P=0.024) and NLR (P=0.028) were effective independent prognostic variables associated with OS. Based on this result, a novel, single inflammation-based combination of fibrinogen and NLR (COF-NLR) score was proposed for the determination of prognosis. Patients with elevated fibrinogen and NLR levels were allocated a score of 2 (n=136), and those that demonstrated elevated levels of one or neither were allocated a score of 1 (n=152) or 0 (n=168), respectively. The 5-year OS rates were significantly poorer for patients with COF-NLR=2 compared with those with COF-NLR=1 or 0 (23.5% vs. 34.2% vs. 50.0%, P<0.001). A subgroup analysis demonstrated that the prognostic significance of COF-NLR was independent of histological subtype, lymph node metastasis and pathological stage. Therefore, COF-NLR has potential as a novel and useful blood marker for predicting tumour progression and the postoperative survival of patients with NSCLC. It may assist clinicians in risk stratification, prognosis predictions and facilitating individualised treatment.

The clinical use of pretreatment NLR, PLR, and LMR in patients with esophageal squamous cell carcinoma: evidence from a meta-analysis

Background and purpose

The relationship between neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and lymphocyte to monocyte ratio (LMR) and the prognostic and clinicopathological significance in patients with esophageal squamous cell carcinoma (ESCC) has been reported by many studies. However, inconsistent results have been presented. The current study aimed to investigate the prognostic and clinicopathological role of NLR, PLR, and LMR in patients with ESCC by meta-analysis.

Methods

Eligible studies were identified in databases and the relationship between NLR/PLR/LMR and the prognosis or clinicopathological features in patients with ESCC was evaluated. OR or HR with 95% CI was calculated to estimate the risk or hazard association.

Result

Twenty-six studies including 8,586 ESCC patients were included for the analysis. We found that high NLR, PLR and low LMR were associated with poor overall survival/cancer-specific survival and event-free survival and malignant phenotypes such as deeper depth of invasion (T), positive lymph node metastasis (N), and advanced TNM stage.

Conclusion

NLR, PLR, and LMR might serve as prognostic markers in patients with ESCC.

Prognostic significance of pretreatment plasma fibrinogen level in patients with digestive system tumors: a meta-analysis

High pretreatment levels of plasma fibrinogen have been widely reported to be a potential predictor of prognosis in digestive system tumors; however, the conclusions are not consistent. Therefore, we performed a meta-analysis to comprehensively assess the prognostic roles of high pretreatment plasma fibrinogen levels in digestive system tumors. We searched for eligible studies in the PubMed, Embase, and Web of Science electronic databases for publications from the database inception to 1 September 2017. The endpoints of interest included overall survival, disease-free survival, and recurrence-free survival. We investigated the relationship between fibrinogenemia and overall survival in colorectal cancer (10 studies), gastric cancer (6), pancreatic cancer (6), hepatocellular carcinoma (7), and esophageal squamous cell carcinoma (10); the pooled results indicated that fibrinogenemia was significantly related to a worse overall survival (hazard ratio (HR) 1.73; 95% confidence interval (CI) 1.52, 1.97; P <0.001; HR 1.71; 95% CI 1.28, 2.28; P <0.001; HR 1.57; 95% CI 1.13, 2.17; P = 0.007; HR 1.89; 95% CI 1.57, 2.27; P <0.001, and HR 1.67; 95% CI 1.35, 2.07; P <0.001). Taken together, an increased pretreatment plasma fibrinogen level was related to worse survival in digestive system tumors, indicating that it could be a useful prognostic marker in these types of tumors.

Prognostic significance of pretreatment plasma fibrinogen in patients with hepatocellular and pancreatic carcinomas: A meta-analysis

BACKGROUND

The high pretreatment plasma fibrinogen has been widely reported to be a possible biomarker for predicting prognosis in hepatocellular carcinoma (HCC) and pancreatic carcinoma (PC), but persuasive conclusion has not been made yet. Thus, we herein conducted a meta-analysis to comprehensively assess the prognostic value of high pretreatment plasma fibrinogen in patients with HCC and PC.

METHOD

We systematically searched PubMed, EMBASE, and Web of Science to identify eligible studies from inception to November 10, 2017.

RESULTS

Finally, a total of 12 publications with 13 studies were included. Of these eligible studies, 5 publications with 6 studies were about pancreatic cancer and 7 were about HCC. The pooled analysis indicated that high plasm fibrinogen level was significantly related to worse overall survival (OS) in HCC [hazard ratio (HR) = 1.87; 95% confidence interval (CI): 1.55-2.24; P < .01]. Similarly, from our result, it was found that high plasm fibrinogen was also significantly associated with worse OS in PC (HR = 1.56; 95% CI: 1.13-2.15; P < .01).

CONCLUSION

Taken together, our meta-analysis confirmed that high plasma fibrinogen level could predict worse survival in HCC and PC.

Prognostic value of combined preoperative fibrinogen and neutrophil-lymphocyte ratio in patients with hepatocellular carcinoma after liver transplantation

OBJECTIVES

Elevated plasma fibrinogen (Fib) correlated with patient's prognosis in several solid tumors. However, few studies have illuminated the relationship between preoperative Fib and prognosis of HCC after liver transplantation. We aimed to clarify the prognostic value of Fib and whether the prognostic accuracy can be enhanced by the combination of Fib and neutrophil-lymphocyte ratio (NLR).

RESULTS

Fib was correlated with Child-pugh stage, alpha-fetoprotein (AFP), size of largest tumor, macro- and micro-vascular invasion. Univariate analysis showed preoperative Fib, AFP, NLR, size of largest tumor, tumor number, macro- and micro- vascular invasion were significantly associated with disease-free survival (DFS) and overall survival (OS) in HCC patients with liver transplantation. After multivariate analysis, only Fib and macro-vascular invasion were independently correlated with DFS and OS. Survival analysis showed that preoperative Fib > 2.345 g/L predicted poor prognosis of patients HCC after liver transplantation. Preoperative Fib showed prognostic value in various subgroups of HCC. Furthermore, the predictive range was expanded by the combination of Fib and NLR.

MATERIALS AND METHODS

Data were collected retrospectively from 130 HCC patients who underwent liver transplantation. Preoperative Fib, NLR and clinicopathologic variables were analyzed. The survival analysis was performed by the Kaplan-Meier method, and compared by the log-rank test. Univariate and multivariate analyses were performed to identify the prognostic factors for DFS and OS.

CONCLUSIONS

Preoperative Fib is an independent effective predictor of prognosis for HCC patients, higher levels of Fib predict poorer outcomes and the combination of Fib and NLR enlarges the prognostic accuracy of testing.

The preoperative sensitive-modified Glasgow prognostic score is superior to the modified Glasgow prognostic score in predicting long-term survival for esophageal squamous cell carcinoma

The present study was designed to investigate the prognostic significance of the preoperative sensitive-modified Glasgow prognostic score (S-mGPS) and its superiority in esophageal squamous cell carcinoma (ESCC). Clinicopathologic characteristics, preoperative albumin and C-reactive protein (CRP) levels were retrospectively collected in 442 patients who underwent transthoracic esophagectomy. The S-mGPS was calculated before surgery based on optimal cutoff values of 45.6 g/L for albumin and 10.0 mg/L for CRP. 360, 74 and 8 cases were assigned an mGPS of 0, 1 and 2, respectively. In contrast, the S-mGPS was 0 in 114, 1 in 258 and 2 in 70 patients. Of the 360 patients with an mGPS of 0, 246 migrated to the S-mGPS-1 group. Both mGPS and S-mGPS were significantly correlated with tumor length, depth of invasion, pathological tumor-node-metastasis (pTNM) stage and adjuvant treatment. In addition, they were significantly associated with disease free survival (DFS) and overall survival (OS) in univariate analysis. Furthermore, multivariate Cox regression analysis identified S-mGPS as an independent prognostic indicator for both DFS [hazard ratio (HR), 1.577; 95% confidence interval (CI), 1.149-2.163; P = 0.005] and OS (HR, 1.762; 95% CI, 1.250-2.484; P = 0.001), but not mGPS (HR, 0.957; 95% CI, 0.692-1.323; P = 0.790 for DFS and HR, 1.089; 95% CI, 0.781-1.517; P = 0.615 for OS, respectively). Moreover, subgroup analysis revealed that the prognostic impact of the S-mGPS was especially striking in pTNM stage II patients. The preoperative S-mGPS is superior to the mGPS as a prognostic predictor in patients with resectable ESCC.

Cumulative score based on preoperative plasma fibrinogen and serum C-reactive protein could predict long-term survival for esophageal squamous cell carcinoma

The present study was to establish a prognostic indicator based on preoperative fibrinogen and C-reactive protein (CRP) (FC score) in esophageal squamous cell carcinoma (ESCC). Clinicopathologic characteristics, preoperative plasma fibrinogen and serum CRP levels were reviewed in patients who underwent transthoracic esophagectomy. The optimal cut-off value for fibrinogen and CRP was defined as 4.0 g/dL and 10.0 mg/L according to previous reports. Patients with elevated fibrinogen and CRP levels were assigned a score of 2, those with only one of these two abnormalities were allocated a score of 1, and those with neither of the two abnormalities were assigned a score of 0. Preoperative FC score was significantly correlated with degree of differentiation, depth of invasion, tumor-node-metastasis (TNM) stage and modified Glasgow Prognostic Score (mGPS). No significant differences in age, gender, tumor length, tumor location, lymph node status or smoking were identified between groups. Univariate survival analysis demonstrated that high preoperative FC score (1/2) was significantly associated with impaired disease free survival (DFS) [hazard ratio (HR), 1.650; 95% confidence interval (CI), 1.181-2.303; P = 0.003] and overall survival (OS) (HR, 1.879; 95% CI, 1.333-2.648; P<0.001), and it remained an independent predictor for both DFS (HR, 1.468; 95% CI, 1.043-2.067; P=0.028) and OS (HR, 2.070; 95% CI, 1.266-3.385; P=0.004) in multivariate Cox regression analysis. Preoperative FC score might represent a new potential marker of worst prognosis that warrants further evaluation in prospective and large cohort studies among ESCC patients who underwent transthoracic esophagectomy.

Prognostic significance of combined fibrinogen concentration and neutrophil-to-lymphocyte ratio in patients with resectable non-small cell lung cancer

Objective

Cancer-associated inflammation and coagulation cascades play vital roles in cancer progression and survival. In this study, we investigated the significance of the combination of preoperative fibrinogen and the neutrophil-to-lymphocyte ratio (NLR) in predicting the survival of patients with non-small cell lung cancer (NSCLC).

Methods

We retrospectively enrolled 589 patients with NSCLC who underwent surgery. The univariate and multivariate Cox survival analyses were used to evaluate the prognostic indicators, including the combination of fibrinogen and NLR (F-NLR). The cut-off values for fibrinogen, NLR, and clinical laboratory variables were defined by the receiver operating characteristic (ROC) curve analysis. According to the ROC curve, the recommended cut-off values for fibrinogen and the NLR were 3.48 g/L and 2.30, respectively. Patients with both a high NLR (≥ 2.30) and hyperfibrinogenemia (≥ 3.48 g/L) were given a score of 2, whereas those with one or neither were scored as 1 or 0, respectively.

Results

Our results showed that F-NLR was an independent prognostic indicator for disease-free survival (DFS) [hazard ratio (HR), 1.466; 95% confidence interval (CI), 1.243-1.730; P < 0.001] and overall survival (OS) (HR, 1.512; 95% CI, 1.283-1.783; P < 0.001). The five-year OS rates were 66.1%, 53.5%, and 33.3% for the F-NLR = 0, F-NLR = 1, and F-NLR = 2, respectively ( P < 0.001). Correspondingly, their five-year DFS rates were 62.2%, 50.3%, and 30.4%, respectively ( P < 0.001). In the subgroup analyses of the pathological stages, the F-NLR level was significantly correlated with DFS and OS in stage I and IIIA cancers.

Conclusions

Preoperative F-NLR score can be used as a valuable prognostic marker for patients with resectable early-stage NSCLC.

A cumulative score based on preoperative fibrinogen and the neutrophil-lymphocyte ratio to predict outcomes in resectable gastric cancer

BACKGROUND

Recent studies have revealed that preoperative fibrinogen and the neutrophil-lymphocyte ratio (NLR) are associated with poor outcome in gastric cancer (GC). We aimed to evaluate whether the fibrinogen and the NLR score had a consistent prognostic value for resectable GC.

METHODS

We analyzed 1,293 consecutive patients who underwent curative surgery for GC. The F-NLR score was 2 for patients with hyperfibrinogenemia (>400 mg/dL) and elevated NLR (≥5.0), 1 for those with one abnormal index, and 0 for those with no abnormal indices.

RESULTS

We found that higher F-NLR scores were associated with larger tumor size, deeper tumor invasion and more lymph node metastasis (all P<0.05). In a multivariate analysis, F-NLR independently predicted postoperative survival (P<0.001). When stratified by tumor-node-metastasis (TNM) stage, the prognostic value of F-NLR was still maintained for stages I-II (P<0.001) and stage III (P=0.003). Of note, F-NLR also effectively stratified overall survival (OS) irrespective of age, adjuvant chemotherapy administration, tumor location and histological grade (all P<0.05). Furthermore, F-NLR and TNM stratified 5-year OS from 61% (F-NLR 0) to 15% (F-NLR 2) and from 92% (stage I) to 37% (stage III), respectively. Utilizing both F-NLR and TNM, 5-year OS ranged from 93% (F-NLR 0, TNM I) to 6% (F-NLR 2, TNM III).

CONCLUSION

The F-NLR score independently predicts outcomes in GC patients after curative surgery. Therefore, it should be implemented in routine clinical practice for identifying more high-risk patients.

Low preoperative albumin-globulin score predicts favorable survival in esophageal squamous cell carcinoma

This study retrospectively investigated the prognostic significance of the preoperative albumin-globulin score (AGS) and albumin/globulin ratio (AGR) in esophageal squamous cell carcinoma (ESCC). A cohort of 458 newly diagnosed ESCC patients who underwent radical esophagectomy in Sun Yat-sen University Cancer Center (Guangzhou, China) between January 2006 and December 2010 were selected into this study. The optimal cut-off value was identified to be 45.6 g/L, 26.9 g/L and 1.30 for albumin (ALB), globulin (GLB) and AGR in terms of survival, respectively. Patients with low ALB levels (< 45.6 g/L) and high GLB levels (≥ 26.9 g/L) were assigned an AGS of 2, those with only one of the two abnormalities were assigned an AGS of 1, and those with neither of the two abnormalities were assigned an AGS of 0. Univariate survival analysis showed that low AGS (0) was significantly associated with favorable disease free survival (DFS) [hazard ratio (HR), 0.635; 95% confidence interval (CI), 0.441-0.914; P = 0.015] and overall survival (OS) (HR, 0.578; 95% CI, 0.387-0.862; P = 0.007), and it remained an independent predictor for OS (HR, 0.630; 95% CI, 0.418-0.952; P = 0.028), but not for DFS (HR, 0.697; 95% CI, 0.479-1.061; P = 0.060) in multivariate models. High AGR (≥ 1.30) was also correlated with favorable DFS (HR, 0.626; 95% CI, 0.430-0.910; P = 0.014) and OS (HR, 0.622; 95% CI, 0.422-0.916; P = 0.016) in univariate analysis, but it failed to be an independent prognostic indicator for DFS (HR, 0.730; 95% CI, 0.494-1.078; P = 0.114) or OS (HR, 0.759; 95% CI, 0.507-1.137; P = 0.181) by multivariate analysis. Low preoperative AGS could serve as a valuable and convenient biochemical marker to predict favorable long-term survival in ESCC patients.

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

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

Preoperative plasma fibrinogen is associated with poor prognosis in esophageal carcinoma: a meta-analysis

PURPOSE

The aim of this meta-analysis was to investigate preoperative plasma fibrinogen (PPF) as a prognostic marker in esophageal carcinoma (EC) by meta-analysis.

METHODS

Relevant studies were sought in the databases including Pubmed, Web of Science, Cochrane library, and Wanfang databases up to Oct 10th, 2017. Hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) were used as effective value, and pooled HRs were synthesized by STATA 14.0 to assess the prognostic impact of PPF on EC patients.

RESULTS

A total of 8 studies with 2827 patients were collected in this meta-analysis. Our results revealed that high PPF was significantly associated with poor OS (HR = 1.90, 95% CI 1.56-2.33, P = 0.000; HR = 1.76, 95% CI 1.28-2.42, P = 0.000) and poor DFS (HR = 1.91, 95% CI 1.50-2.43, P = 0.000; HR = 1.51, 95% CI 1.16-1.97, P = 0.000) in EC patients from univariate and multivariate analysis results, respectively, which suggested that EC patients with high PPF will suffer from high postoperative mortality and recurrence rate.

CONCLUSION

High PPF was significantly associated with poor OS and DFS in EC patients. Fibrinogen can serve as a prognostic marker and even a future targeting molecule during the treatment of EC patients.

C-reactive protein-albumin ratio is an independent prognostic predictor of tumor recurrence in stage IIIA-N2 lung adenocarcinoma patients

OBJECTIVE

To systematically evaluate the prognostic value of nutrition/inflammation-based markers for recurrence-free survival (RFS) in pN2-stage IIIA lung adenocarcinoma patients.

MATERIALS AND METHODS

Data from 156 patients who had pathologically confirmed pN2-stage IIIA primary lung adenocarcinoma and received complete surgical resection from 2010 to 2014 were retrospectively analyzed. The data for Glasgow prognostic score (GPS), modified GPS (mGPS), high-sensitivity mGPS, C-reactive protein/albumin ratio (CAR), neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, and prognostic nutritional index were analyzed. Univariate and multivariate Cox proportional-hazards regression analyses were used to identify the prognostic factors associated with RFS.

RESULTS

The optimal cutoff value for the CAR was set at 0.6. A significant correlation was found between the CAR and RFS (P=0.001) by univariate analysis. Multivariate analysis between RFS and the factors selected from univariate analysis showed that ECOG performance status, pneumonectomy, multi-level N2, and high CAR were independent predictors of RFS.

CONCLUSION

The CAR was the best prognostic marker to predict tumor recurrence in pN2-stage IIIA lung adenocarcinoma patients among the 7 nutrition/inflammation-based markers. The preoperative CAR may identify patients with a high risk of postoperative tumor recurrence.

The association of plasma fibrinogen with clinicopathological features and prognosis in esophageal cancer patients

Background

Numerous studies have shown that plasma fibrinogen was linked to esophageal cancer (EC) risk. However, the clinical significance of plasma fibrinogen in EC patients remain unclear and need to be further clarified.

Results

A total of 2865 patients with EC from 11 published studies were included in this meta-analysis. The prognostic and clinical relevance of plasma fibrinogen were evaluated in EC patients. Statistical significance of the pooled hazard ratio (HR) was found for overall survival (OS), disease free survival (DFS) and recurrence-free survival (RFS) in EC. Subgroup analyses for OS were also performed to confirm the prognostic value of plasma fibrinogen. Additionally, the overall results indicated that elevated plasma fibrinogen was significantly associated with tumor invasion, lymph node metastasis (LNM) and clinical stage.

Materials and Methods

A comprehensive literature retrieval was performed in PubMed, Embase, Cochrane database, Web of science and Chinese National Knowledge Infrastructure (CNKI) and Wanfang databases to identify relevant studies published prior to April 15, 2017.

Conclusions

Elevated plasma fibrinogen could be served as a promising biomarker for predicting a poor prognosis and unfavorable clinicopathologic features for EC.

Prognostic value of lymphocyte-to-monocyte ratio among Asian lung cancer patients: a systematic review and meta-analysis

Purpose

Numerous studies have reported the prognostic significance of lymphocyte-to-monocyte ratio (LMR) in malignancies, but its prognostic value among lung cancer remains controversial. This meta-analysis aimed to explore the prognostic significance of LMR in lung cancer patients.

Results

Eight studies including 3954 patients were included in this meta-analysis. Pooled results indicated that low LMR was significantly associated with poorer progression-free survival (hazard ratio (HR): 1.431, 95% confidence interval (CI): 1.294–1.582, p < 0.001) and overall survival (OS) (HR: 1.651, 95% CI: 1.306–2.086, p < 0.001), compared with high LMR. Similar results were observed in subgroups regardless of treatment, LMR cut-off value, or districts. However, no significant correlation between the LMR and OS was observed in the small cell lung cancer (SCLC) subgroup (HR = 1.262, 95% CI: 0.864–1.841, p = 0.229).

Materials and Methods

Identified literatures were extracted and retrieved from PubMed, Embase, Web of Science, and the Cochrane Library databases; All eligible studies focused on the association between LMR and the prognosis of lung cancer.

Conclusions

Low LMR is associated with poor outcomes among lung cancer patients. Further studies are needed to discuss the correlation between LMR and lung cancer prognosis.

Fibrinogen promotes malignant biological tumor behavior involving epithelial-mesenchymal transition via the p-AKT/p-mTOR pathway in esophageal squamous cell carcinoma

PURPOSE

Hyperfibrinogenemia is associated with unfavorable prognosis and advanced tumor behavior in various malignancies, including esophageal squamous cell carcinoma (ESCC). However, its biological function in ESCC is unknown. The present study was designed to further validate the prognostic value of preoperative plasma hyperfibrinogenemia and evaluate the biological role of fibrinogen, as well as the underlying mechanism in ESCC.

METHODS

Data from 452 cases with newly diagnosed ESCC followed by curative surgery between 2006 and 2010 were retrospectively evaluated. The Clauss method was utilized to measure the preoperative plasma fibrinogen level. Correlations between the fibrinogen level and clinicopathologic characteristics and survival analysis were performed. The effects of fibrinogen on malignant behaviors, including tumor cell viability, colony formation, migration, and invasion, were also investigated.

RESULTS

The optimal cut-off value for plasma fibrinogen level was defined as 4.0 g/L according to recommendations. Thus, the proportion of hyperfibrinogenemia was 24.8% (112/452). Preoperative plasma hyperfibrinogenemia was significantly associated with advanced tumor length, deep tumor invasion, advanced tumor-node-metastasis stage, alcohol consumption, a higher white blood cell count, a higher platelet count, and high globulin levels. Univariate survival analysis revealed that compared to those with normal plasma fibrinogen levels, patients with hyperfibrinogenemia tended to have poorer disease-free survival (DFS) [hazard ratio (HR), 1.692; 95% confidence interval (CI), 1.304-2.196; P < 0.001] and overall survival (OS) (HR 1.864; 95% CI 1.424-2.440; P < 0.001). In the multivariate Cox regression models, these factors remained independent predictors for impaired DFS (HR 1.491; 95% CI 1.138-1.955; P = 0.004) and OS (HR 1.648; 95% CI 1.246-2.180; P < 0.001) after adjusting for other confounding variables. In addition, fibrinogen could significantly promote cell migration and invasion but not proliferation. Moreover, it could also induce epithelial-mesenchymal transition (EMT) and increase the levels of p-PTEN, p-AKT, and p-mTOR in ESCC cell lines.

CONCLUSIONS

Preoperative plasma hyperfibrinogenemia might serve as an independent predictor of unfavorable survival in ESCC. Furthermore, fibrinogen may promote cell motility by inducing EMT via the p-AKT/p-mTOR pathway.
