Combined pretreatment neutrophil-lymphocyte ratio and platelet-lymphocyte ratio predicts survival and prognosis in patients with non-metastatic nasopharyngeal carcinoma: a retrospective study

The clinical significance of the combination of neutrophil–lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) is unclear. This study investigated the predictive value of pretreatment NLR (pre-NLR) combined with pretreatment PLR (pre-PLR) for the survival and prognosis of nasopharyngeal carcinoma (NPC). A total of 765 patients with non-metastatic NPC from two hospitals were retrospectively analyzed. The pre-NLR-PLR groups were as follows: HRG, high pre-NLR and high pre-PLR. MRG, high pre-NLR and low pre-PLR or low pre-NLR and high pre-PLR. LRG, neither high pre-NLR nor high pre-PLR. Receiver operating characteristic (ROC) curves were used to identify the cutoff-value and discriminant performance of the model. We compared survival rates and factors affecting the prognosis among different groups. The 5-year overall survival (OS), local regional recurrence-free survival (LRRFS) and distant metastasis-free survival (DMFS) of NPC patients in HRG were significantly poorer than those in MRG and LRG. The pre-NLR-PLR score was positively correlated with T stage, clinical stage, ECOG, and pathological classification. Multivariate cox regression analysis showed that pre-NLR-PLR scoring system, ECOG, pre-ALB, pre-CRP and pre-LMR were independent risk factors affecting 5-year OS, LRRFS and DMFS. The ROC curve showed that area under the curve (AUC) values of pre-NLR-PLR of 5-year OS, LRRFS and DMFS were higher than those of pre-NLR and pre-PLR. pre-NLR-PLR is an independent risk factor for the prognosis of NPC. The pre-NLR-PLR scoring system can be used as an individualized clinical assessment tool to predict the prognosis of patients with non-metastatic NPC more accurately and easily.

Evaluation of tadalafil supplementation on the neutrophil/lymphocyte and the platelet/lymphocyte ratios in patients with erectile dysfunction: A prospective study.

We aimed to evaluate the effect of daily 5 mg tadalafil on the neutrophil/lymphocyte ratio (NLR) and the platelet/lymphocyte ratio (PLR) in patients with erectile dysfunction (ED). 30 subjects with ED were given tadalafil as well as 30 subjects with ED who were not receiving tadalafil were recruited. 30 healthy individuals served as controls. Receiver operating characteristic curve (ROC) showed that the best cut off point of pre-treatment and post treatment NLR in the ED treatment group was found <1.51, <1.51, sensitivity of 68.3%, 58.3%, specificity of 53.3%, 53.3%, lower bound of 0.558, 0.517, upper bound of 0.789, 0.757, total accuracy of 67.4%, 63.7% and p 0.003, 0.0025, respectively. Additionally, the best cut off point of pre-treatment and post treatment PLR in the ED treatment group was found <5.89, <5.99, sensitivity of 65%, 63.3%, specificity of 63.3%, 53.3%, lower bound of 0.515, 0.435, upper bound of 0.755, 0.687, total accuracy of 63.5%, 56.1% and p 0.027, 0.341, respectively. Daily 5 mg Tadalafil supplementation significantly improves erectile function through decreasing these markers as well as depression and anxiety.

The diagnostic value of systemic inflammatory response markers as predictors of epithelial ovarian cancer

Background: Early detection of ovarian neoplasms confers a better outcome and prognosis for patients. Although newer diagnostic modalities have been recently developed, the availability and accessibility of complete blood count parameters make it a convenient and cost-effective marker for malignancy. Objectives were to evaluate the diagnostic accuracy of pretreatment neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in patients with late-stage epithelial ovarian malignancy at the University of Port Harcourt Teaching Hospital. Methods: A prospective analysis of fifty-seven women with histologic diagnosis of epithelial ovarian cancer who were managed at the University of Port Harcourt Teaching Hospital between January 1, 2018, and December 31, 2022, was conducted. A data collection form was used to obtain socio-demographic and clinico-pathological characteristics from the patients after informed consent was obtained. Pretreatment levels of NLR and PLR were determined from complete blood count. The Receiver Operating Characteristic (ROC) curve analysis was used to assess the predictive accuracy of the haematological parameters for late-stage epithelial ovarian cancer. Results: Higher values of NLR and PLR were significantly associated with the stage of ovarian cancer (p=0.001). The optimal cut-off points based on ROC curve analyses for NLR and PLR were found to be 2.6 (AUC=0.61, p&gt;0.05), and 155.8 (AUC=0.62, p&gt;0.05) respectively. However, none of the haematological parameters could be used as predictive markers for advanced-stage ovarian cancer in this study. Conclusions: Pretreatment NLR and PLR cannot be used as a stand-alone predictor of advanced ovarian cancer, and should be correlated with other clinical, laboratory and radiologic parameters.

D-D and PLR, NLR combined forecasting first-line treatment: The short-term curative effect and prognosis of patients with SCLC.

The aim of this study was to evaluate the difference in D-dimer (D-D) combined with the platelet lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) before treatment in small cell lung cancer (SCLC) patients receiving first-line treatment and to analyze the efficacy and prognosis. We retrospectively collected the records of SCLC patients treated in our hospital from February 2019 to January 2023 and finally included 100 patients. A binary logistic regression analysis method was applied to analyze the relationship between D-D, PLR, and NLR and short-term efficacy. Univariate and multivariate Cox regression analyses were utilized to estimate the individual effect of plasma parameters on progression-free survival (PFS). The optimal cutoff values of D-D, PLR, and NLR for predicting survival outcome were determined by receiver operating characteristic curve analysis. Kaplan-Meier survival analysis was utilized to examine the correlation between D-D, PLR, and NLR the prognosis of SCLC patients. PLR was associated with a short-term curative effect in patients with SCLC (odds ratio: 0.326, 95% confidence interval [CI]: 0.135 0.790). Univariate Cox regression showed that D-D (hazard ratio [HR]: 0.495, 95% CI: 0.323-0.758), PLR (HR:0.420, 95% CI: 0.269-0.655) and NLR (HR: 0.407, 95% CI: 0.263-0.630) were associated with PFS in SCLC patients (P < .05). Multivariate Cox regression analysis showed that PLR (HR: 2.395, 95% CI: 1.468-3.906) and NLR (HR: 2.148, 95% CI: 1.319-3.499) correlated significantly with PFS (P < .05). The optimal cutoff values of D-D, PLR and NLR for predicting PFS were 0.88 mg/L (65.4% and 68.7%), 195.44 (61.5% and 81.2%) and 3.63 (63.5% and 81.2%), respectively, and the corresponding area under receiver (AUC) operating characteristic curve 0.691 (95% CI: 0.587-0.795), 0.721 (95% CI: 0.620-0.822) and 0.714 (95% CI: 0.614-0.815). When D-D was used in combination with PLR or NLR, the corresponding AUCs were 0.737 (95% CI: 0.640-0.835) and 0.761 (95% CI: 0.667-0.855). Pretreatment PLR is an independent predictor of short-term efficacy in SCLC patients. Pretreatment D-D, PLR and NLR are potential biochemical markers for predicting the prognosis of SCLC patients treated with first-line treatment. When D-D is combined with PLR and NLR, it shows stronger predictive ability.

Prognostic Significance of Pre-Treatment Neutrophil-Lymphocyte Ratio and Platelet-Lymphocyte Ratio in Head and Neck Malignancies.

Carcinoma is the second most common cause of death worldwide. The neutrophil-lymphocyte ratio (NLR) and the platelet-lymphocyte ratio (PLR) are essential markers of inflammation and tumorigenesis in various cancers including head and neck cancers. Pretreatment platelet- lymphocytic ratio can be used as an independent predictor of mortality whereas neutrophil- lymphocytic ratio is an independent predictor of recurrence. The main aim of this study is to compare the pre-treatment neutrophil lymphocyte ratio and platelet-lymphocyte ratio in the patients of head and neck malignancies with those of the control group. 100 patients with histologically diagnosed cases of head and neck malignancies. Age and sex matched healthy subjects attending Otorhinolaryngology out-patient department for any other complaints (100 control subjects). Complete blood count had been done to calculate absolute neutrophil count and absolute lymphocyte count. The mean age of the subjects in the study group was 55.73 ± 11.56years. In control group, the mean age group was 54.11 ± 10.46years. NLR and PLR significantly increased in cases than controls. NLR associated with T stage, histological type and histological grade but not with site and nodal involvement. PLR associated with T stage, metastasis but not with the histological grade, histological type, site and nodal involvement. From this study, we conclude that pre-treatment NLR and PLR were closely associated both with the size of primary tumor and also with the stage of malignant disease in patients of head and neck malignancies.

Association between neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and survival in undifferentiated pleomorphic sarcoma (NLR, PLR, and overall survival in UPS)

Background and objectivesCancer-related inflammation has been shown to be a driver of tumor growth and progression, and there has been a recent focus on identifying markers of the inflammatory tumor microenvironment. Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are inflammatory indices that have been identified as prognostic biomarkers in various malignancies. However, there is limited and conflicting data regarding their prognostic value in soft tissue sarcoma (STS) and specifically in undifferentiated pleomorphic sarcoma (UPS). MethodsThis was a retrospective review of patients who underwent surgical treatment for primary UPS from 1993 to 2021. Cutoff values for NLR and PLR were determined by receiver operating curve analysis. Cox proportional hazards regression was used to determine prognostic factors on univariate and multivariate analysis. ResultsEighty-six patients were included. The optimal cutoff value was 3.3 for NLR and 190 for PLR. Both high NLR (HR 2.44; 95% CI 1.29–4.63; p = 0.005) and high PLR (HR 1.99; 95% CI 1.08–3.67, p = 0.02) were associated with worse OS on univariate analysis. On multivariate analysis, metastasis at presentation and radiotherapy were independently predictive of OS, but high NLR (HR 1.30; 95% CI 0.64–2.98; p = 0.41) and high PLR (HR 1.63; 95% CI 0.82–3.25; p = 0.17) were not predictive of survival. ConclusionsHigh pre-treatment NLR and PLR were associated with decreased overall survival but were not independent predictors of survival in patients undergoing resection for UPS. Until additional prospective studies can be done, survival outcomes are best predicted using previously established patient- and tumor-specific factors.

A nomogram based on hematological markers to predict radiosensitivity in patients with esophageal squamous cell carcinoma.

This study aimed to determine the predictive value of pretreatment levels of hematological markers on the radiosensitivity of patients with esophageal squamous cell carcinoma (ESCC). The specific hematological markers assessed included total lymphocyte count (TLC), neutrophil count, platelet count, monocyte count, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and lymphocyte-monocyte ratio (LMR). A total of 353 ESCC patients who received radiotherapy (RT) alone or concurrent RT between 2015 and 2019 were reviewed. Pretreatment levels of hematological markers (NLR, PLR, LMR, and TLC) were used to assess the radiosensitivity of individual patients. Receiver operating characteristics curves were used to determine optimal cutoff values. Multivariate logistic models with radiosensitivity were established with meaningful results used for univariate analyses. Finally, a nomogram was developed and validated from the calibration curve and concordance index. One month after RT, 121 (34.3%) cases were shown to have low levels of radiosensitivity based on hematological markers. Univariate analyses showed that NLR, PLR, LMR, and TLC were associated with high levels of radiosensitivity (all markers, P < .05). Due to the collinearity between NLR, PLR, and LMR, these markers were separately evaluated by multivariate analysis. Multivariate analysis showed that high pretreatment NLP and PLR were independently associated with high radiosensitivity. In contrast, high pretreatment LMR and TLC were independent biomarkers associated with lower radiosensitivity. The concordance index of the nomogram was 0.737, and the calibration curves predicted by the nomogram were highly consistent with the observed experimental findings. Pretreatment hematologic markers (NLR, PLR, LMR, and TLC) can be used to predict the radiosensitivity of patients with ESCC accurately.

The prognostic value of C-reactive protein/albumin ratio and platelet-lymphocyte ratio in patients with pancreatic cancer.

678 Background: Pancreatic cancer is a highly malignant tumor with poor prognosis. Therefore, identification of prognostic markers is very crucial for improved risk stratification in pancreatic cancer patients. Although various systemic inflammatory markers have been investigated for their prognostic roles in pancreatic cancer, inconsistent results have been found across studies. Accordingly, the present study aimed to identify the prognostic value of inflammatory markers for patients with pancreatic cancer. Methods: The study enrolled 185 patients with pancreatic cancer. The inflammatory markers, namely, the modified Glasgow Prognostic Score (mGPS), the prognostic nutritional index (PNI), the neutrophil/lymphocyte ratio (NLR), the platelet/lymphocyte ratio (PLR), the C-reactive protein (CRP)/albumin ratio (CAR), the platelet/albumin ratio (PAR), and the CRP/lymphocyte ratio (CLR), were evaluated. Receiver operating characteristics curve analysis was performed to determine the cut-off values. The Cox proportional hazards model was used to analyze the factors affecting the prognosis. Results: The mean age of the patients was 64.1 years (with a standard deviation of 11.1), and their average overall survival (OS) was 10.5 months (95% confidence interval [CI] = 9.7–11.4). In the univariate analysis, metastatic disease, carbohydrate antigen (CA)19-9, mGPS, PNI, NLR, PLR, CAR, and CLR were significantly associated with OS ( P&lt; 0.05). In the multivariate analysis, metastatic diseases (hazard ratio [HR] = 2.52, 95% CI = 1.03–6.15, P = 0.04), CA19-9 (HR = 3.96, 95% CI = 2.01–7.79, P&lt; 0.001), PLR (HR = 2.37, 95% CI = 1.11–5.04, P = 0.03), and CAR (HR = 4.45, 95% CI = 2.19–9.03, P &lt; 0.001) were identified as independent prognostic factors for OS. Conclusions: Pretreatment PLR, CAR, CA 19-9 , and metastatic diseases were found to be independent indicators of poor prognosis in patients with pancreatic cancer. We believe that our findings will shed light on the identification of prognostic factors, which might enable a better risk stratification in pancreatic cancer patients.

Evaluation of systemic inflammatory and nutritional indexes in locally advanced gastric cancer treated with adjuvant chemoradiotherapy after D2 dissection.

Many studies have shown that the peripheral blood inflammatory index and nutritional index, such as the platelet lymphocyte ratio (PLR), neutrophil lymphocyte ratio (NLR), lymphocyte monocyte ratio (LMR), systemic inflammation response index (SIRI), pan-immune-inflammation value (PIV), systemic immune-inflammation index (SII), and prognostic nutrition index (PNI), are independent prognostic factors for tumors. The present study aimed to investigate the prognostic role of these peripheral blood indexes before treatment in locally advanced gastric cancer (LAGC) treated with adjuvant chemoradiotherapy after D2 dissection. A total of 89 patients with LAGC who underwent D2 gastrectomy and adjuvant chemoradiotherapy at our hospital from 2010-2018 were eligible. Systemic inflammatory indicators before treatment were evaluated. Receiver operating characteristic curve (ROC), Kaplan-Meier analysis, and Cox regression were utilized for prognosis evaluation. The median follow-up time was 29.1 (4.1-115.8) months. The overall survival at 3 years (OS) and the disease-free survival (DFS) were 78.9% and 59.1%, respectively. According to the ROC curve for 3-year DFS, the best cut-off values of pre-treatment NLR, PLR, LMR, SII, SIRI, PIV and PNI were 1.7, 109.3, 2.9, 369.2, 0.58, 218.7, and 48, respectively. Multivariate Cox regression analysis showed that NLR was an independent prognostic factor for DFS (HR 2.991, 95%CI 1.085-8.248, P = 0.034). Kaplan-Meier analysis showed that a higher NLR (>1.70) was significantly associated with a poorer OS (3-year OS: 68.8% vs 92.9%, P = 0.045) and DFS (3-year DFS: 47.5% vs 80.9%, P = 0.005). In terms of the free locoregional recurrence rate (LRR), the prognosis of patients with high NLR was also significantly worse than those with low NLR (70.2% vs 96.0%, P = 0.017). Paraaortic lymph nodes were the most common site of LRR (7/14 patients). The seven cases of paraaortic lymph node metastasis occurred in patients with high NLR. In our retrospective analysis, we found that pretreatment NLR could serve as a prognostic factor for survival in LAGC treated with adjuvant chemoradiotherapy after D2 dissection, especially for the prediction of LRR and paraaortic lymph node metastasis. Prospective studies are needed to confirm our findings.

Role of neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, lymphocyte-monocyte ratio and platelets in prognosis of patients with prostate cancer.

The aim of the present analysis was to evaluate the platelet-lymphocyte ratio (PLR), neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelets (PLT) and neutrophil level for their prognostic values in patients with prostate cancer who had been treated with radiotherapy. A retrospective analysis of 152 patients who were treated in the Radiotherapy Department at Maria Sklodowska-Curie National Research Institute of Oncology (Gliwice, Poland) between January 2012 and December 2014 was performed. The prognostic value (overall survival; OS) of the pre-treatment PLR, NLR, LMR, PLT, neutrophil level and other laboratory factors such as: leukocyte, lymphocyte, monocyte, hemoglobin, RBC, prostate-specific antigen level (PSA), Gleason score, age, smoking and comorbid condition were assessed using univariate analysis. The cut-off point was determined for NLR as 'elevated' at >4.66, LMR >3.26 and the PLR was considered 'elevated' at >89.6. Median follow-up was 4.9 years. The 5 and 7-year OS rates were 81.5 and 72.2%, respectively. In univariate analysis higher NLR (P=0.007), higher level of PLT (P=0.004), higher level of neutrophils (P=0.013), elevated level of leukocyte (P=0.043) and lymphocyte (P=0.043) were factors significantly associated with decreased OS. No difference was found for PLR (P=0.308) and LMR (P=0.109). The other factor associated with decreased OS were: higher Gleason score (>7; P=0.005), higher PSA level (>20 ng/dl; P=0.0001), smoking (P=0.003) and older age (>70 years; P=0.018). In multivariate analysis, NLR, LMR, leukocyte and RBC were independently associated with prognosis in patients with prostate cancer. Elevated pre-treatment NLR [hazard ratio (HR)=10.83; P=0.001), LMR (HR=3.14; P=0.007) and higher leukocyte level (HR=3.14; P=0.007) were independently associated with increased mortality risk. Overall, pre-treatment NLR, PLR, leukocyte and RBC levels were revealed to be independent prognostic factors.

Prognostic Role of Systemic Inflammatory Markers in Patients Undergoing Surgical Resection for Oral Squamous Cell Carcinoma.

Background: A high platelet–lymphocyte ratio (PLR) is a marker of systemic inflammation and, together with the neutrophil–lymphocyte ratio (NLR), is associated with poor outcomes in several cancers. We investigated the prognostic value of PLR and other systemic inflammatory markers, such as NLR, systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI), in oral squamous cell carcinoma (OSCC) patients undergoing surgical resection. Methods: We derived PLR, NLR, SII, and SIRI from a retrospective chart review of 269 consecutive OSCC patients. The complete blood count examined in the immediate preoperative period was used to compute PLR, NLR, SII, and SIRI. We analyzed the relationship between these systemic inflammatory markers and the clinicopathologic characteristics, disease-specific survival (DSS), and progression-free survival (PFS) of patients. Results: In the univariate analysis, high PLR and SII were significantly associated with worse DSS and PFS (all p < 0.05). In the multivariate analysis, PLR (HR 2.36, 95% CI 1.28–4.36 for DSS; HR 1.80, 95% CI 1.06–3.06 for PFS) was an independent predictor of survival outcomes. When PLR was analyzed as a continuous variable, the relationship between the outcome and preoperative PLR was not monotonically linear. In the subgroup analysis, PLR was more strongly associated with DSS and PFS in patients who were male, had stage III/IV OSCC, or had lymph node metastasis. Conclusion: Our data suggest that in OSCC patients, the pretreatment PLR is an independent predictor of DSS and PFS. The PLR is a readily available biomarker that will improve prognostication and risk stratification in OSCC.

Pulmonary neuroendocrine tumors: study of 266 cases focusing on clinicopathological characteristics, immunophenotype, and prognosis

ObjectivePulmonary neuroendocrine tumors (PNETs) consist of small-cell lung cancer (SCLC), large-cell neuroendocrine carcinoma (LCNEC), typical carcinoid (TC), and atypical carcinoid (AC). We aimed to analyze the immunophenotypic, metastatic, and prognostic risk factors for PNETs.Materials and methodsA total of 266 patients with PNETs were enrolled, including 219 patients with SCLC, 18 patients with LCNEC, 11 patients with TC, and 18 patients with AC. Clinicopathological characteristics and immunophenotypes were compared among the subtypes of PNETs. Risk factors for metastasis, progression-free survival (PFS), and overall survival (OS) were analyzed.ResultsThyroid transcription factor-1 (TTF-1) and the Ki-67 index were significantly different among subtypes of PNETs (all P < 0.05). Smoking (OR, 2.633; P = 0.031), high pretreatment carcinoembryonic antigen (CEA > 5 ng/ml: OR, 3.084; P = 0.014), and poorly differentiated pathotypes (P = 0.001) were independent risk factors for lymph-node metastasis. Smoking (OR, 2.071; P = 0.027) and high pretreatment CEA (OR, 2.260; P = 0.007) were independent risk factors for distant metastasis. Results of the multivariate Cox regression model showed pretreatment CEA (HR, 1.674; P = 0.008) and lymphocyte–monocyte ratio (LMR) (HR = 0.478, P = 0.007) were significantly associated with PFS; BMI (P = 0.031), lymph-node metastasis (HR = 4.534, P = 0.001), poorly differentiated pathotypes (P = 0.015), platelet–lymphocyte ratio (PLR) (HR = 2.305, P = 0.004), and LMR (HR = 0.524, P = 0.045) were significantly associated with OS.ConclusionsPNETs are a group of highly heterogeneous tumors with different clinical manifestations, pathological features, and prognoses. Knowing clinicopathological characteristics and immunophenotypes of PNETs is significant for diagnosis. Pretreatment PLR, LMR, and CEA have certain value in the prognosis of PNETs.

Pre-treatment hematological parameters as a cost effective predictive marker for response to concurrent chemo radiation in locally advanced cervical cancer

IntroductionLocally advanced cervical cancer is still a major cause of mortality in developing countries. Recently, personalized medicine has changed the treatment paradigm for many solid cancers but no robust biomarkers has yet been validated for predicting response to chemo radiation in cervical cancer patients. AimTo assess the role of hematological parameters as a cost-effective predictive marker of response to concurrent chemo radiation in cervical cancer patients. Materials and MethodThis is a retrospective analysis of 90 cervical cancer patients treated with concurrent chemo radiation in a tertiary cancer center. Clinical details of the patients were extracted from the case records. For end point evaluation, the pre-treatment levels of hemoglobin, neutrophil, lymphocyte, platelet, platelet lymphocyte ratio (PLR) and neutrophil lymphocyte ratio (NLR) were compared and statistically analyzed between responders and non-responders. The optimal cutoff values of hematological parameters were estimated by the receiver operating characteristics (ROC) curve. ResultOut of 90 patients, 60 (66.66%) were complete responders and remaining 30 (33.33%) were non-responders. The mean value of platelet, NLR, and PLR was significantly higher in the non-responder group. ROC curve analysis showed the optimal cut-off value of pre-treatment Hb, PLT, NLR and PLR to be 11 gm/dl, 3, 177 × 109/L, and 70 respectively. ConclusionOur study suggests that simple hematological markers like NLR, PLT count and PLR could be used as a cost effective pretreatment predictive marker for response to chemo radiation in cervical cancer patients.

Assessment of systematic inflammatory and nutritional indexes in extensive-stage small-cell lung cancer treated with first-line chemotherapy and atezolizumab.

The present study aims to investigate the prognostic role of systematic inflammatory and nutritional indexes in extensive-stage small-cell lung cancer (ES-SCLC) treated with first-line chemotherapy and atezolizumab. Prospective cohort population involving 53 patients were identified from NCT03041311 trial. The following peripheral blood-derived inflammatory and nutritional indexes, including neutrophil-lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), prognostic nutrition index (PNI), advanced lung cancer inflammation index (ALI), and lung immune prognostic index (LIPI) were evaluated. The optimal cut-off values of the ALI, LMR, NLR, PLR, PNI, SII and SIRI were 323.23, 2.73, 2.57, 119.23, 48, 533.28 and 2.32, respectively. With a median follow-up of 17.1months, the 1-year OS and PFS were 56% and 8%, respectively. Multivariate analysis showed that PLR was the only independent prognostic factors for OS among ES-SCLC patients treated with chemotherapy and atezolizumab (HR 4.63, 95%CI: 1.00-21.46, p = 0.05). K-M analysis showed that the OS and PFS for patients with high PLR (> 119.23) were significantly poorer than these with low PLR (≤ 119.23) (p = 0.0004 for OS and p = 0.014 for PFS). In external validation set, prognosis of patients with high PLR was also significantly poorer than these with low PLR in terms of OS (p = 0.038) and PFS (p = 0.028). Pre-treatment PLR could serve as a valuable independent prognostic factor for ES-SCLC who receive chemotherapy and immune checkpoint inhibitors. Further, prospective studies are still needed to confirm our findings.

Platelet/lymphocyte ratio is a significant prognostic factor for targeted therapy in patients with EGFR-mutated non-small-cell lung cancer.

ObjectiveTo analyze the prognostic significance of the pretreatment platelet/lymphocyte ratio (PLR) for targeted therapy in patients with epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC).MethodsWe conducted a retrospective study of 96 patients with EGFR-mutated advanced NSCLC who were treated at Dongguan People’s Hospital, Southern Medical University from May 2014 to December 2017. All patients received EGFR-targeted therapy until disease progression, unacceptable toxicity, or other factors. Approximately 3 days before the initial treatment, data including a detailed clinical history, physical examination, radiographic results, pathological diagnosis, and laboratory parameters including complete blood cell counts and albumin levels were evaluated.ResultsPatients in the PLR ≥ 190 group had shorter progression-free survival (PFS) than those in the PLR < 190 group. Furthermore, the 1-year PFS rate was worse in the PLR ≥ 190 group than in the PLR< 190 group. Multivariate analysis indicated the possible role of PLR as a prognostic factor for patients with advanced NSCLC who received EGFR-targeted therapy.ConclusionsPretreatment PLR may be an independent prognostic factor for patients with NSCLC receiving EGFR tyrosine kinase inhibitor treatment. Further studies are needed to identify the impact of PLR on EGFR-mutated NSCLC.

Clinicopathological and prognostic significance of platelet-lymphocyte ratio (PLR) in gastric cancer: an updated meta-analysis

BackgroundPre-treatment PLR (platelet-lymphocyte ratio) was reported to be associated with the prognosis in gastric cancer (GC), but the results remain inconclusive. This meta-analysis aimed to investigate the prognostic potential of the pre-treatment PLR in gastric cancer.MethodsWe performed a systematic literature search in PubMed, Embase, and the Cochrane Library to identify eligible publications. The hazard ratio (HR)/odds ratio (OR) and its 95% confidence (CI) of survival outcomes and clinicopathological parameters were calculated.ResultsA total of 49 studies (51 cohorts), collecting data from 28,929 GC patients, were included in the final analysis. The pooled results demonstrated that the elevated pre-treatment PLR was significantly associated with poor overall survival (OS) (HR 1.37, 95% CI 1.26–1.49, p < 0.001; I2 = 79.90%, Ph < 0.001) and disease-free survival (DFS) (HR 1.52, 95% CI 1.22–1.90, p < 0.001, I2 = 88.6%, Ph < 0.001). Furthermore, the patients with the elevated PLR had a higher risk of lymph node metastasis (OR = 1.17, 95% CI 1.02–1.33, p = 0.023), serosal invasion (T3+T4) (OR = 1.34, 95% CI 1.10–1.64, p = 0.003), and increased advanced stage (III+IV) (OR = 1.20, 95% CI 1.06–1.37, p = 0.004).ConclusionsAn elevated pre-treatment PLR was a prognostic factor for poor OS and DFS and associated with poor clinicopathological parameters in GC patients.

Predictive value of neutrophil-lymphocyte ratio and platelet-lymphocyte ratio in non-small cell lung cancer patients treated with immune checkpoint inhibitors: A meta-analysis

BackgroundHigh neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are associated with poor prognosis in cancer patients treated with Immune checkpoint inhibitors (ICIs). However, whether this relationship exists in non-small cell lung cancer (NSCLC) patients remains unclear. Thus, this meta-analysis was conducted to investigate the prognostic role of NLR and PLR in NSCLC treated with ICIs. MethodsEligible studies that evaluated the value of pre-treatment or post-treatment NLR/PLR in NSCLC patients received ICIs were obtained by searching PubMed, Web of Science, Cochrane Library, and EMBASE. The pooled hazard ratio (HR) and 95% confidence interval (CI) were used to assess the relationship between NLR/PLR and overall survival (OS) and progression-free survival (PFS). Subgroup analysis and publication bias were conducted to investigate heterogeneity. Results1845 NSCLC patients from 21 studies were included and three ICIs(nivolumab, pembrolizumab, and atezolizumab) were used. Overall, high NLR was associated with poor OS (HR: 2.50, 95% CI:1.79–3.51, P < 0.001) and PFS (HR: 1.77, 95% CI:1.51–2.01, P < 0.001). Subgroup analyses were consistent with the pooled results. Similarly, the pooled results for PLR showed that elevated PLR was related to inferior OS (HR: 1.93, 95% CI: 1.51–2.01, P < 0.001) and PFS (HR: 1.57, 95%CI: 1.30–1.90, P < 0.001). However, the subgroup analysis based on test time indicated that there was no significant correlation between post-treatment PLR and survival outcomes. ConclusionNLR and pre-treatment PLR could serve as prognostic biomarkers in NSCLC patients treated with ICIs. However, the value of post-treatment PLR needs further to be evaluated.

Predictive value of neutrophil to lymphocyte ratio and platelet to lymphocyte ratio in advanced hepatocellular carcinoma patients treated with anti-PD-1 therapy.

BackgroundCurrently, there are no recognized or validated biomarkers to identify hepatocellular carcinoma patients (HCC) likely to benefit from anti–PD‐1 therapy. We evaluated the relationship between neutrophil‐lymphocyte ratio (NLR) and platelet‐lymphocyte ratio (PLR) and survival outcomes, pretreatment and after three doses (posttreatment) of nivolumab in HCC patients.MethodsMedical records of HCC patients treated with nivolumab between June 2016 and July 2018 were reviewed. Kaplan‐Meier analysis and the log‐rank test were used to calculate and compare overall survival between NLR < 5 Vs ≥ 5 and among PLR tertiles.ResultsA total of 103 patients were identified. Median age was 66 (29‐89) years. Median treatment duration was 26 (2‐149) weeks. Sixty‐four (62%) patients had Child‐Pugh class A (CP‐A) liver function. Barcelona Clinic Liver Cancer stage was B in 20 (19%) and C in 83 (81%) patients. CP‐A patients who achieved a partial or complete response had significantly lower posttreatment NLR and PLR (P < .001 for both) compared to patients who had stable disease or progression of disease. No relationship was observed between response and pretreatment NLR and PLR. NLR < 5 was associated with improved OS compared to NLR ≥ 5 both pretreatment (23 Vs10 months, P = .004) and posttreatment (35 Vs 9 months, P < .0001). Survival also differed significantly among PLR tertiles both pre‐ (P = .05) and posttreatment (P = .013). In a multivariable model, posttreatment NLR (HR = 1.10, P < .001) and PLR (HR = 1.002, P < .001) were strongly associated with survival. In a composite model of posttreatment NLR and PLR, a combination of high NLR and PLR was associated with an eightfold increased risk of death (HR = 8.3, P < .001).ConclusionsThis study suggests a strong predictive role of these inflammatory cell ratios in the posttreatment setting in HCC patients treated with anti anti–PD‐1 therapy and should be evaluated in a larger cohort.

Are Inflammatory Markers Significant Prognostic Factors for Head and Neck Cancer Patients?

Introduction: Recent studies have reported that elevated levels of platelets and inflammatory markers are associated with poor treatment outcomes among patients with solid tumours, but reports are conflicting in head and neck cancer (HNC) patients. Objective: To establish if pre-treatment anti-inflammatory markers can be used as a prognostic tool of overall survival and tumour control among HNC patients. Methods: We retrospectively reviewed the pre-treatment platelet/lymphocyte ratio (PLR) and neutrophil/lymphocyte ratio (NLR) of 147 HNC patients from 2014 to 2018 and analysed their association with tumour progression and overall treatment outcomes. The optimal cut-off was established at >200 for high PLR and >2.85 for high NLR. Results: After adjusting for age, disease stage, and treatment, patients with higher PLR had an almost 3 times higher risk of mortality during the study period than patients with normal PLR (hazard ratio [HR] 2.79, 95% confidence interval [CI] 1.43–5.47, p < 0.01). Furthermore, the patients with higher NLR had an >2.5 times higher risk of mortality than those with normal NLR (HR 2.62, 95% CI 1.19–5.81, p = 0.02). Conclusion: This observational study shows that elevated PLR and NLR in HNC patients, who were treated with either surgery or primarily chemoradiotherapy, are associated with poor overall survival.

Prognostic Value of the Neutrophil-Lymphocyte, Platelet-Lymphocyte, and Monocyte-Lymphocyte Ratios in Male Breast Cancer Patients

Background: The aim of the present study was to assess the blood neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and monocyte-lymphocyte ratio (MLR) as prognostic factors in male breast cancer (BC) patients. Methods: A retrospective analysis of 38 male BC patients who were treated at the Institute of Oncology (Gliwice, Poland) between January 2005 and December 2018 was performed. The prognostic value (in terms of overall survival [OS]) of the pretreatment PLR, NLR, and MLR was assessed by univariate analysis. Results: We observed a tendency towards worse OS among male BC patients with lymph node metastases (N+) (5-year OS: 43.5 vs. 73.9%; p = 0.087), a greater tumor size (T4 vs. T1 + T2) (42.0 vs. 70.5%; p = 0.061), and a negative steroid receptor status (PR–) (28.6 vs. 65.6%; p = 0.109). Patients with a family history of cancer had significantly better 5-year OS than patients without a family history of cancer (86.3 vs. 35.0%; p = 0.001). Younger male BC patients (age ≤56 years) had better 5-year OS than patients >56 years of age (82.5 vs. 42.3%; p = 0.028). The 5-year OS was lower among patients with a lower lymphocyte value (≤1.82 × 10³) (29.0 vs. 75.6%; p = 0.010). There was a tendency towards worse OS among patients with a higher platelet count (>281 × 10³) (4.5-year OS: 16.7 vs. 65.8%; p = 0.056). The 5-year OS was insignificantly lower in the group with NLRs >2.74 than in the group with NLRs ≤2.74 (37.5 vs. 62.8%; p = 0.078). A worse OS rate was associated with an elevated PLR (>169.1) (22.2 vs. 70.1%; p = 0.008). Similarly, there was worse OS in the group with higher MLR (>0.30) (41.8 vs. 78.3%; p = 0.025). Conclusions: The present results reveal that elevated MLRs (>0.30) and PLRs (>169.1) are associated with poor OS among male BC patients. Similarly, but insignificantly, an elevated NLR (>2.74) affected OS.
