Pretreatment neutrophil-to-lymphocyte ratio and its dynamic changes are associated with the overall survival in advanced cancer patients undergoing palliative care

Impact of baseline lymphopenia on outcomes of definitive treatment for locally advanced cervical cancer

Objectives

The purpose of this study is to evaluate the association between lymphopenia and survival in women with locally advanced cervical cancer (LACC) treated with definitive chemoradiation (CRT).

Methods

We retrospectively reviewed patients with LACC treated at a single institution from 2004 to 2021. Patient and treatment characteristics were recorded along with baseline absolute lymphocyte counts (ALC). Overall survival (OS), progression free survival (PFS), and local control (LC) were calculated from start of treatment to date of last follow-up. Cox regression and competing risks regression model were performed to evaluate whether baseline ALC was associated with OS, PFS, or LC.

Results

246 patients met study inclusion criteria with stage IB - IV disease with a median follow up of 2.8 years (range 0.2-13.4 years). 5-year OS, PFS, and LC were 68.4 % (95 % CI 61.7-75.9), 57.2 % (95 % CI 50.4-64.8), and 79.0 % (95 % CI 73.0-84.4), respectively. Baseline lymphopenia (ALC < 1000 cells/mm3) was present in 12.5 % of patients. OS was improved in the patients without lymphopenia, with a 5-year OS of 69.0 % (95 % CI 61.6-77.3) versus 63.0 % (95 % CI 47.6-83.3)in the lymphopenia group (p = 0.233), though this did not meet statistical significance. PFS also trended towards improvement in patients without baseline lymphopenia, with a 5-year PFS of 58.5 % (95 % CI 51.2-66.8) versus 48.5 % (95 % CI 32.8-71.7), p = 0.220. No significant difference was found for LC in the patients without lymphopenia, p = 0.745.

Conclusions

In this single institution experience of LACC treated with definitive CRT, we found that baseline lymphopenia trends toward inferior OS and PFS.

A prognostic model using the neutrophil-albumin ratio and PG-SGA to predict overall survival in advanced palliative lung cancer

OBJECTIVE

Inflammation and malnutrition are common in patients with advanced lung cancer undergoing palliative care, and their survival time is limited. In this study, we created a prognostic model using the Inflam-Nutri score to predict the survival of these patients.

METHODS

A retrospective cohort study was conducted on 223 patients with advanced, histologically confirmed unresectable lung cancer treated between January 2017 and December 2018. The cutoff values of the neutrophil-albumin ratio (NAR) and Patient-Generated Subjective Global Assessment (PG-SGA) score were determined by the X-tile program. Least absolute shrinkage and selection operator (LASSO) Cox regression and multivariate Cox regression analysis were performed to identify prognostic factors of overall survival (OS). We then established a nomogram model. The model was assessed by a validation cohort of 72 patients treated between January 2019 and December 2019. The predictive accuracy and discriminative ability were assessed by the concordance index (C-index), a plot of the calibration curve and risk group stratification. The clinical usefulness of the nomogram was measured by decision curve analysis (DCA).

RESULTS

The nomogram incorporated stage, supportive care treatment, the NAR and the PG-SGA score. The calibration curve presented good performance in the validation cohorts. The model showed discriminability with a C-index of 0.76 in the training cohort and 0.77 in the validation cohort. DCA demonstrated that the nomogram provided a higher net benefit across a wide, reasonable range of threshold probabilities for predicting OS. The survival curves of different risk groups were clearly separated.

CONCLUSIONS

The NAR and PG-SGA scores were independently related to survival. Our prognostic model based on the Inflam-Nutri score could provide prognostic information for advanced palliative lung cancer patients and physicians.

Evaluation of Optimal Threshold of Neutrophil-Lymphocyte Ratio and Its Association With Survival Outcomes Among Patients With Head and Neck Cancer

IMPORTANCE

Given the role of inflammation in cancer progression, neutrophil-lymphocyte ratio (NLR) from peripheral blood has been suggested as a readout of systemic inflammation and a prognostic marker in several solid malignant neoplasms. However, optimal threshold for NLR in US patients with head and neck cancer remains unclear.

OBJECTIVE

To evaluate the optimal NLR threshold as a potential prognostic biomarker for survival outcomes.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study was conducted at a single institution. Participants included 496 patients with nonmetastatic head and neck cancer who underwent chemoradiation from April 2007 to March 2021. Statistical analysis was performed from September to December 2021.

EXPOSURES

High vs low NLR.

MAIN OUTCOMES AND MEASURES

Overall survival (OS) and cancer-specific survival (CSS).

RESULTS

A total of 496 patients (411 male patients [82.9%]; 432 White patients [87.1%]; 64 patients with other race or ethnicity [12.9%]; median [IQR] age, 61 [55-67] years) were identified. Median (IQR) follow-up was 44.4 (22.8-74.0) months. Thresholds of NLR for both OS and CSS were 5.71. High NLR above 5.71 was associated with worse OS (adjusted hazard ratio [aHR], 1.97; 95% CI, 1.26-3.09; P = .003) and CSS (aHR, 2.33; 95% CI, 1.38-3.95; P = .002). On logistic multivariable analysis, patients were more likely to have high NLR if they had higher T and N staging (T3-4: aOR, 4.07; 95% CI, 1.92-9.16; P < .001; N2: aOR, 2.97; 95% CI, 1.04-9.17; P = .049; N3: aOR, 11.21; 95% CI, 2.84-46.97; P < .001), but less likely if they had a good performance status (Karnofsky Performance Status 90-100: aOR, 0.29; 95% CI, 0.14-0.59; P < .001). Among 331 patients (66.7%) with available human papillomavirus (HPV) data, high NLR was not associated with OS (HPV-negative: aHR, 2.46; 95% CI, 0.96-6.31; P = .06; HPV-positive: aHR, 1.17; 95% CI, 0.38-3.56; P = .78) and CSS (HPV-negative: aHR, 2.55; 95% CI, 0.81-7.99; P = .11; HPV-positive: aHR, 1.45; 95% CI, 0.44-4.76; P = .54).

CONCLUSIONS AND RELEVANCE

High NLR was associated with worse survival. Patients with substantial disease burden and poor performance status were more likely to have high NLR. These findings suggest that further studies would be warranted to investigate the role of such prognostic marker to identify patients at risk to tailor interventions.

NEUTROPHIL-LYMPHOCYTE RATIO PREDICTS SHORT-TERM MORTALITY IN PATIENTS HOSPITALIZED FOR ACUTE DECOMPENSATION OF CIRRHOSIS

BACKGROUND

Individuals with cirrhosis have a chronic systemic inflammation associated with an immune dysfunction, affecting the progression of the liver disease. The neutrophil-lymphocyte ratio (NLR) was proposed as a marker of systemic inflammatory response and survival in patients with cirrhosis.

OBJECTIVE

Evaluate the prognostic role of NLR in cirrhotic patients and its relation with inflammatory cytokines(IL-6, IL-10 and IL-17).

METHODS

In this prospective study two groups were evaluated: 1) Stable cirrhotic in outpatient follow-up (n=193); 2) Hospitalized cirrhotic for acute decompensation for at least 48 hours (n=334) with admission and 48 hours tests evaluation. Circulating inflammatory cytokines were available for 130 hospitalized patients.

RESULTS

In outpatients with stable cirrhosis, NLR correlated with MELD score and other variables associated with severity of disease. However, after a median of 32 months of follow up NLR was not associated with mortality (HR 1.058, 95%CI 0.900-1.243; P=0.495). In hospitalized patients, NLR at 48-hour after admission was independently associated with 90-day survival (HR 1.061, 95%CI 1.020-1.103; P=0.003) in multivariate Cox-regression analysis. The 90-day Kaplan-Meier survival probability was 87% for patients with a 48-hour NLR <3.6 and 62% for NLR ≥3.6 (P<0.001). Elevation of NLR in the first 48 hours was also independently associated with mortality (HR 2.038, 95%CI 1295-3207; P=0.002). The 90-day Kaplan-Meier survival probability was 83% when NLR did not increase and 62% when NLR increased (P<0.001). IL-6, IL-10 and IL-17 at admission were positively correlated with both admission and 48-hour NLR. Lower levels of baseline IL-10 were associated with NLR increase during first 48-hour.

CONCLUSION

NLR evaluated at 48 hours of hospitalization and its early increase after admission were independently associated with short-term mortality in patients hospitalized for acute decompensation of cirrhosis.

A nomogram to predict short-term outcome of radiotherapy or chemoradiotherapy based on pre/post-treatment inflammatory biomarkers and their dynamic changes in esophageal squamous cell carcinoma

OBJECTIVE

We initially aimed to investigate pre/post-treatment inflammatory biomarkers (pre/post-IBs) and their dynamic changes (delta-IBs) on the short-term outcome (STO) of radiotherapy or chemoradiotherapy in esophageal squamous cell carcinoma (ESCC). Furthermore, a nomogram was built to provide an accurate prediction of STO.

METHODS

The STO using the treatment response evaluation was assessed according to RECIST 1.1 at 1 month after radiotherapy or chemoradiotherapy. The IBs (absolute lymphocyte counts (ALC), neutrophil/lymphocyte (NLR), platelet/lymphocyte (PLR), and lymphocyte/monocyte (LMR)) and clinical variables were collected and analyzed from 398 ESCC patients at Shandong Cancer Hospital between 2015 and 2019. The nomogram was then established for predicting STO.

RESULTS

Pre-ALC and pre-LMR significantly increased, pre-NLR and pre-PLR significantly decreased during radiotherapy or chemoradiotherapy (all P < 0.001). Meanwhile, there was a positive correlation between delta-NLR as well as delta-PLR (r = 0.621) and delta-LMR (r = 0.613), whereas a negatively correlated between delta-LMR and delta-PLR (r = -0.573). Multivariate analysis indicated that gender [OR, 0.473; 95%CI, 0.274-0.816; P = 0.007], pre-ALC [OR, 0.554; 95%CI, 0.335-0.915; P = 0.021], pre-NLR [OR, 3.176; 95%CI, 1.733-5.823; P < 0.001], post-NLR [OR, 2.418; 95%CI, 1.271-4.600; P = 0.007] and delta-NLR [OR, 1.929; 95%CI, 1.035-3.595; P = 0.039] were statistically significant with STO. And c-index of the nomogram established by combining all independent predictors for STO was 0.770 [95%CI, 0.719-0.820].

CONCLUSION

Pre-NLR, pre-ALC, post-NLR, and delta-NLR were significant with STO in ESCC patients treated with radiotherapy or chemoradiotherapy. Further, pre-NLR had the best predictive value, and the developed nomogram with superior prediction ability for STO could assist in patients counseling and guide to make individual treatments.

The usefulness of systemic inflammatory markers as diagnostic indicators of the pathogenesis of diabetic macular edema

PURPOSE

To investigate the usefulness of systemic inflammatory markers [i.e., white blood cell and platelet counts, mean platelet volume, and their ratios] as diagnostic markers of the pathogenesis of diabetic macular edema.

METHODS

The study cohort included 80 diabetic macular edema patients (40 with diabetic retinopathy and 40 without) and 40 healthy age- and sex-matched controls. Neutrophil, lymphocyte, monocyte, and platelet counts, and the mean platelet volume were determined from peripheral blood samples, and the monocyte/lymphocyte, platelet/lymphocyte, and mean platelet volume/lymphocyte, and neutrophil/lymphocyte ratios were calculated and compared among groups.

RESULTS

The mean neutrophil/lymphocyte ratio of the diabetic macular edema and non-diabetic macular edema groups was higher than that of the control group, and the value of the diabetic macular edema group was higher than that of the non-diabetic macular edema group (p<0.001 in diabetic macular edema vs. control, p=0.04 in non-diabetic macular edema vs. control, and p=0.03 in diabetic macular edema vs. non-diabetic macular edema). A neutrophil/lymphocyte cutoff value of ≥2.26 was identified as an indicator of the pathogenesis of diabetic macular edema with a sensitivity of 85% and specificity of 74%. The mean platelet volume of the diabetic macular edema group was higher than those of the non-diabetic macular edema and control groups, while those of the non-diabetic macular edema and control groups were similar (diabetic macular edema vs. non-diabetic macular edema, p=0.08; diabetic macular edema vs. control, p=0.02; and non- diabetic macular edema vs. control, p=0.78). All other parameters were similar between groups (all p>0.05).

CONCLUSION

The neutrophil/lymphocyte ratio and mean platelet volume of the diabetic macular edema group were higher than those of the non-diabetic macular edema and control groups. A neutrophil/lymphocyte ratio cutoff value of ≥2.26 was identified as an indicator of the pathogenesis of diabetic macular edema with high sensitivity and specificity. Moreover, the neutrophil/ lymphocyte ratio of the non-diabetic macular edema group was higher than that of the control group.

The post-treatment neutrophil-to-lymphocyte ratio and changes in this ratio predict survival after treatment of stage III non-small-cell lung cancer with conventionally fractionated radiotherapy

Aim: To investigate the predictive potential of post-treatment neutrophil-to-lymphocyte ratio (NLR) and changes in this ratio (ΔNLR) for stage III non-small-cell lung cancer (NSCLC) patients who received conventionally fractionated radiotherapy (CFRT). Patients & methods: The data of 168 NSCLC patients treated at the Shandong Cancer Hospital were analyzed retrospectively. The relationship between progression-free survival (PFS), overall survival (OS) and post-treatment NLR and ΔNLR were analyzed using both Kaplan-Meier and Cox regression methods. Results: Kaplan-Meier survival analyses showed that post-treatment NLR and ΔNLR were associated with PFS (p < 0.001) and OS (p < 0.001) after CFRT. Multivariate analyses revealed that ΔNLR was an independent predictor of PFS (p = 0.001) and OS (p = 0.018). Post-treatment NLR can only be used as an independent predictor of PFS (p = 0.040). Conclusion: Our results demonstrated the prognostic value of the ΔNLR in predicting PFS and OS in stage III NSCLC patients undergoing CFRT. However, post-treatment NLR has predictive value only for PFS.

The Optimal Cutoff Value of Neutrophil/Lymphocyte Ratio for Severe Grades of Diabetic Retinopathy

OBJECTIVES

The aim of this study was to define the optimal cutoff value of the neutrophil/lymphocyte ratio (NLR) to predict severe grades of diabetic retinopathy (DR).

METHODS

A total of 40 patients with proliferative DR (PDR) and 40 patients with severe non-proliferative DR (NPDR) were included this prospective, case control study, and 35 age- and sex-matched healthy subjects were recruited as a control group. White blood cell (WBC) count mean values and ratios were compared between the groups.

RESULTS

The groups were statistically similar in terms of age and sex. The neutrophil, lymphocyte, monocyte, platelet counts, and main platelet volume (MPV) values were similar in all 3 groups (all p values >0.05). The mean NLR was 2.67±1.02 in the PDR cases, 2.16±0.58 in severe NPDR, and 1.85±0.49 in the control group, which represented a statistically significant difference between the 3 groups (p=0.003). In post-hoc analysis, the NLR of the PDR and severe NPDR groups was statistically significantly greater than that of the control group (p=0.002 and p=0.048, respectively), but there was no statistically significant difference between the PDR and severe NPDR groups (p=0.083). The monocyte/lymphocyte, platelet/lymphocyte, and MPV/lymphocyte ratios were also similar in all 3 groups (all p values >0.05).

CONCLUSION

An NLR value of 2.11 or more predicted DR (PDR or severe NPDR) with a sensitivity of 76% and a specificity of 80%.

The Relationship of Neutrophil to Lymphocyte Ratio with Vitreomacular Traction Syndrome

This study was conducted to reveal the role of systemic low-grade inflammation by calculating the Neutrophil/Lymphocyte Ratio (NLR) in Vitreomacular Traction Syndrome (VMTS) of different etiologies. A retrospective examination was made of the medical records at a tertiary referral hospital. The study included 31 patients with diabetic VMTS, 27 patients with idiopathic VMTS, and 35 healthy subjects as the control group. The White Blood Cell (WBC) counts and Neutrophil-to-Lymphocyte Ratio (NLR) was compared. There were insignificant differences between the groups in terms of mean age and female/male ratio (P>0.05). The mean ± Standard Deviation (SD) of NLR was calculated as 2.43 ± 0.83 in the diabetic VMTS group, 2.38 0.96 in the idiopathic VMTS group, and 1.83 WBC: White blood cell; VMTS: Vitreomacular traction syndrome; SD: standard deviation; µL: microliter; fL: femtolitre; n: number. 0.52 in the control group (P=0.007). The values of the diabetic and idiopathic VMTS groups were significantly higher than those of the control group (P=0.002 and P=0.032, respectively). However, differences between the diabetic and idiopathic VMTS groups were insignificant (P=0.651). This study found significantly higher NLR in patients with diabetic and idiopathic VMTS than the control group. Elevated NLR could therefore be a potential indicator of VMTS, irrespective of the etiology.

Optimal cut-off for neutrophil-to-lymphocyte ratio: Fact or Fantasy? A prospective cohort study in metastatic cancer patients

This study assessed the prognostic value of pre-treatment neutrophil-to-lymphocyte ratio (NLR) in patients with metastatic solid tumors. Clinical and biological data for patients with metastatic solid tumors treated in an oncology outpatient department and prospectively followed by a call center (PROCHE program) between January 2008 and December 2011 were analyzed. All patients with an NLR value within 28 days before the first cycle of first-line of chemotherapy were included (cohort 1). To assess influence of chemotherapy line on NLR prognostic value, data from patients treated with later chemotherapy lines were also analyzed (cohort 2). Adjusted multivariate Cox regressions with or without non-linear and time-dependent effects were performed. Optimal NLR cut-off was investigated by time-dependent sensitivity analysis using several indices. There were 317 and 134 patients in cohorts 1 and 2, respectively. Elevated NLR was associated with worse survival (hazard ratio [HR] for death, 1.35 [95% confidence interval 1.19-1.54]; p<0.0001). The optimal NLR cut-off in cohort 1 was dependent on index used and time of assessment: HR values were non-significant at a cut-off of 3.0 (1.34 [0.99-1.32], but significant when the cut-off was 4.0 (1.53 [1.11-2.10]). NLR was linearly related to mortality risk; in subgroup analysis, no significant interaction was found with co-variables or tumor localization overall (cohorts 1+2). Pre-treatment NLR is a useful prognostic tool in patients with metastatic solid tumors, irrespective of primary tumor site, chemotherapy line, age, gender and performance status. However, using an NLR cut-off value for clinical decision-making requires extreme caution.

Neutrophil-lymphocyte ratio kinetics in patients with advanced solid tumours on phase I trials of PD-1/PD-L1 inhibitors

BACKGROUND

Although the neutrophil-lymphocyte ratio (NLR) is prognostic in many oncological settings, its significance in the immunotherapy era is unknown. Mechanistically, PD-1/PD-L1 inhibitors may alter NLR. We sought to characterise NLR kinetics in patients with advanced solid tumours treated with PD-1/PD-L1 inhibitors.

METHODS

Electronic records of patients treated with PD-1/PD-L1 inhibitors on phase I trials across three sites were reviewed. A high NLR (hNLR) was predefined as >5. Univariate logistic regression models were used for toxicity, response analyses and Cox models for overall survival (OS) and progression-free survival analyses. Landmark analyses were performed (cycle two, three). Longitudinal analysis of NLR was performed utilising a mixed effect regression model.

RESULTS

The median OS for patients with hNLR was 8.5 months and 19.4 for patients with low NLR, (hazard ratio [HR] = 1.85, 95% confidence interval [CI] 1.15-2.96, p = 0.01). On landmark analysis, hNLR was significantly associated with inferior OS at all time points with a similar magnitude of effect over time (p < 0.05). On multivariate analysis, NLR was associated with OS (HR 1.06, 95% CI 1.01-1.11, p = 0.01). NLR did not correlate with increased immune toxicity. Longitudinally, NLR correlated with response: NLR decreased by 0.09 (95% CI: -0.15 to -0.02; p = 0.01) per month in responders compared with non-responders.

CONCLUSIONS

hNLR at baseline and during treatment is adversely prognostic in patients with advanced malignancies receiving PD-1/PD-L1 blockade. Importantly, NLR reduced over time in responders to immunotherapy. Taken together, these data suggest that baseline and longitudinal NLR may have utility as a unique biomarker to aid clinical decision-making in patients receiving immunotherapy.

Lymphocyte count or percentage: which can better predict the prognosis of advanced cancer patients following palliative care?

Background

The lymphocytes played an important role in the natural history of cancer. The aim of this study was to explore the prognostic value of lymphocyte count and percentage for survival in advanced cancer patients receiving palliative care.

Methods

A retrospective review of clinicopathological data from 378 consecutive advanced cancer patients and 106 extended follow-up patients treated with palliative care was conducted. Kaplan–Meier curves and multivariate cox regression analyses were used to evaluate the relationships of peripheral lymphocyte count (LC) and lymphocyte to white blood cell ratio (LWR) with overall survival (OS).

Results

The median values for pretreatment LC and LWR were 1.1 (IQR, 0.8 ~ 1.5 × 10⁹/L) and 0.138 (IQR, 0.086 ~ 0.208). The median survival times across LWR quartiles were 19, 47, 79, and 101 days (P < 0.001). Multivariate analysis indicated that patients in the highest quartiles of LC and LWR had an HR of 1.082 (95% CI 0.777 ~ 1.506, P = 0.642) and 0.466 (95% CI 0.328 ~ 0.661, P < 0.001), respectively, compared with patients in the lowest quartiles. Furthermore, only the dynamic changes of LWR were confirmed as an independent prognostic factor for overall survival during the follow-up (HR = 0.396, 95% CI 0.243 ~ 0.668; P = 0.001), as were primary tumor site and ECOG. No effect was observed for the dynamic changes of LC.

Conclusions

Our findings demonstrate that measurement of the dynamic changes of LWR prior to treatment and during follow-up may represent a simple and new powerful prognostic factor for patients with advanced cancer, unlike measurement of LC. As a bedside marker of immune status, the prognostic role of LWR should be further evaluated in prospective studies.

Assessment of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and platelet count as predictors of long-term outcome after R0 resection for colorectal cancer

Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and platelet count (PC) were shown to be prognostic in several solid malignancies. We analysed 603 R0 resected patients to assess whether NLR, PLR and PC correlate with other well-known prognostic factors and survival of patients with colorectal cancer (CRC). Receiver operating characteristic (ROC) curve analysis was performed to define cut-off values for high and low ratios of these indices. Univariate and multivariate analysis were used to determine the prognostic value of NLR, PLR and PC for overall and cancer-related survival. The distribution of NLR, PLR and PC in CRC patients was compared with 5270 healthy blood donors. The distribution of NLR, PLR and PC was significantly different between CRC patients and controls (all p < 0.05). A significant but heterogeneous association was found between the main CRC prognostic factors and high values of NLR, PLR and PC. Survival appeared to be worse in patients with high NLR with cancers in AJCC/UICC TNM Stages I-IV; nonetheless its prognostic value was not confirmed for cancer-related survival in multivariate analysis. After stratification of patients according to AJCC/UICC TNM stages, high PC value was significantly correlated with overall and cancer-related survival in TNM stage IV patients.

The diagnostic value of white blood cell, neutrophil, neutrophil-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio in patients with primary angle closure glaucoma

Objective

Inflammatory mechanisms may have a role in the pathogenesis of primary angle closure glaucoma (PACG). The objective of this study was to investigate the diagnostic value of white blood cell (WBC), neutrophil, neutrophil to lymphocyte ratio (NLR), and lymphocyte to monocyte ratio (LMR) in patients with PACG and its association with glaucoma severity.

Method

The study was retrospectively assessed in 771 consecutive PACG patients and 770 control subjects, laboratory parameters and clinical parameters were obtained from a medical data platform. Patients were divided into three groups with different severity based on perimetry, i.e. mild (mean deviation (MD) ≤6.00 dB), moderate (12 dB≥ MD>6 dB) and severe (MD>12 dB). We developed a nomogram to specifically identify individual patient’s risk.

Results

The mean levels of neutrophil, NLR and WBC was higher in PACG than control group, and lowest in the mild PACG group, followed by moderate PACG and severe PACG (p<0.05). The AUROC value of NLR and LMR was found to be 0.719, 0.699, respectively. Multiple linear regressions showed that there was a significant correlation between WBC and MD (B=0.151, p<0.001), neutrophil and MD (B=0.143, p=0.003), NLR and MD (B=0.144, p=0.001), LMR and MD (B=-0.100, p=0.034). Logistic regression analyses revealed that WBC (OR=1.208, 95%CI=1.179-1.238), neutrophil (OR=1.598, 95%CI=1.541-1.656), NLR (OR=2.313, 95%CI=2.200-2.431), and LMR (OR=0.682, 95%CI=0.666-0.699) were associated with PACG.

Conclusion

Our study suggested that WBC, neutrophil, NLR, and LMR was related with PACG, and NLR and LMR may be useful as biomarkers.

Neutrophil count and percentage: potential independent prognostic indicators for advanced cancer patients in a palliative care setting

The purpose of this study was to evaluate the count and percentage of neutrophils as prognostic indicators in advanced cancer patients undergoing palliative care. 378 consecutive patients receiving treatment at the palliative care unit of Fudan University Shanghai Cancer Center between July 2013 and October 2015 were reviewed. In 106 of these patients, the data were extended during the follow-up. The cut-off values selected for the neutrophil count and percentage were 8.0×109/L and 85%, respectively. Both a high pretreatment neutrophil count (HR = 1.828, 95% CI: 1.409∼2.371, P<0.001) and a high pretreatment neutrophil percentage (HR = 1.475, 95% CI: 1.106∼1.967, P=0.008) were independent prognostic factors for decreased overall survival. Furthermore, in the follow-up cohort of readmitted patients (n = 106), patients with a newly increased neutrophil count or percentage were respectively, 1.837 (95% CI: 1.096∼3.079) and 3.268 (95% CI: 1.848∼5.778) times more likely to have a poor prognosis compared with patients with low neutrophil conditions (P=0.021, P<0.001). In conclusions, both high pretreatment or newly increased count and percentage of neutrophils were confirmed as independent prognostic factors for adverse outcomes. These parameters may be used as stratification factors in identifying advanced cancer patients with poor prognosis in palliative care settings.

The Preoperative Neutrophil-To-Lymphocyte Ratio Is a Novel Immune Parameter for the Prognosis of Esophageal Basaloid Squamous Cell Carcinoma

Background

The pretreatment neutrophil-to-lymphocyte ratio (NLR) is an independent predictor of prognosis in various malignancies, but its predictive capacity in basaloid squamous cell carcinoma of the esophagus (BSCCE) remains unclear. We aim to determine the value of the inflammation-related factors, including the NLR, neutrophil-to-monocyte ratio (NMR), and albumin levels, in predicting BSCCE prognosis.

Methods

We retrospectively analyzed the records of 121 patients with pathologically diagnosed BSCCE that underwent a curative esophagectomy from January 2007 to December 2014. Univariate and multivariate analyses were used to identify prognostic factors for overall survival (OS) and recurrence-free survival (RFS).

Results

The preoperative NLR was correlated with the tumor length and NMR. In OS univariate analyses, a high NLR (>1.77), high NMR (>12.31), and low albumin (≤40.0 g/L) level were significantly associated with a poorer survival in BSCCE. The median OS was significantly greater in low NLR (≤1.77) than in the high NLR (>1.77) patients (51.0 vs. 31.0 months; P = 0.008). In multivariate analyses, only the NLR was an independent prognostic factor for OS (hazard ratio (HR), 2.030; 95% confidence interval (CI), 1.262–3.264; P = 0.003). A high NLR was also an independent predictor of a poorer RFS in BSCCE (HR, 2.222; 95% CI, 1.407–3.508; P = 0.001); the median RFS for low (≤1.77) and high (> 1.77) NLR patients was 44.0 months and 14.0 months, respectively. NLR remained a strong prognostic indicator for OS in stage I/II patients and a preoperative NLR>1.77 was predictive of a poor RFS in both stage I/II and stage III patients.

Conclusions

We show that the preoperative NLR, a convenient and cost-effective biomarker, may serve as a prognostic indicator for BSCCE patients following curative surgery.
