Associations of systemic immune-inflammation index with high risk for prostate cancer in middle-aged and older US males: A population-based study. Immun Inflamm Dis 2024; 12:e1327. [PMID: 38923408 PMCID: PMC11194977 DOI: 10.1002/iid3.1327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 05/26/2024] [Accepted: 06/10/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND Systemic immune-inflammation index (SII) provides convincing evaluation of systemic immune and inflammatory condition in human body. Its correlation with prostate cancer (PCa) risk remains uncharted. The principal objective of this investigation was to elucidate the association between SII and the risk for PCa in middle-aged and elderly males. MATERIALS AND METHODS Analysis entailed multivariate linear and logistic regression, generalized additive model, and smoothing curve fitting using resource from 2007 to 2010 National Health and Nutrition Examination Survey (NHANES). To ascertain robustness and consistency of this association across different demographic strata, we conducted rigorous subgroup analyses and interaction tests. RESULTS Among 3359 participants, those with elevated SII displayed higher total prostate-specific antigen (tPSA) levels, higher risk for PCa, and lower free/total PSA (f/t PSA) ratio. Specifically, each unit increase of log2 (SII) was associated with a 0.22 ng/mL increase in tPSA (β: 0.22, 95% confidence intervals [CI] 0.05-0.38), a 2.22% decline in f/t PSA ratio (β: -2.22, 95% CI -3.20 to -1.23), and a 52% increased odds of being at high risk for PCa (odds ratio [OR]: 1.52, 95% CI 1.13-2.04). People in the top quartile of log2 (SII) exhibited 0.55 ng/mL increased tPSA (β: 0.55, 95% CI 0.19-0.90), 4.39% reduced f/t PSA ratio (β: -4.39, 95% CI -6.50 to -2.27), and 168% increased odds of being at high risk for PCa (OR: 2.68, 95% CI 1.32-5.46) compared to those in the bottom quartile. CONCLUSION Systemic immune and inflammatory condition, as represented by SII, is independently and positively associated with tPSA levels and the risk for PCa, as well as independently and negatively associated with f/t PSA ratio among middle-aged and older US males. These findings may enhance the effectiveness of PCa screening in predicting positive biopsy results.

Abstract
There is evidence that the systemic inflammatory response may have an impact on prostate-specific antigen (PSA) levels. However, the relationship between the platelet-to-lymphocyte ratio (PLR) and PSA remains unclear. As a result, the relationship between PLR and PSA using the National Health and Nutrition Examination Survey (NHANES) database was examined. After the screening, 6,638 participants out of 52,186 in the NHANES survey conducted between 2001 to 2010 were suitable for the present study. The PLR was the independent variable in the present study, and PSA was the dependent variable. The selected subjects in the present study had an average age of 58.563±11.848 years. After controlling for covariates, the results showed that with every increase in PLR, the PSA concentration increased by 0.004 ng/ml (0.001, 0.007). This difference was statistically significant. Furthermore, a smoothing curve based on a fully adjusted model was created to investigate the possibility of a linear relationship between PLR and PSA concentration in men from USA. In men from USA, an independent and positive correlation between PLR and PSA was identified, which could potentially result in overdiagnosis of asymptomatic prostate cancer in populations with higher PLR levels.

Abstract
Hypoxemia is a clinical characteristic of pulmonary embolism (PE). Hypoxemia is associated with variations in serum prostate-specific antigen (PSA) levels. Thus, the present study aimed to determine serum PSA levels in patients with PE, which may be helpful in improving clinical evaluation in screening for prostate diseases in those with PE. Clinical data from 61 consecutive male patients with PE and 113 age-matched healthy male controls were retrospectively analyzed. The pulmonary artery obstruction index (PAOI) was used to evaluate the pulmonary embolic burden. Compared with healthy controls, serum total PSA (tPSA) levels were significantly increased (P = .003), and free PSA (fPSA)/tPSA ratio was significantly decreased in patients with PE (P < .001). There was no significantly difference in serum fPSA levels between patients with PE and healthy controls (P = .253). A significant positive association was observed between serum tPSA levels and PAOI in patients with PE (β = .270, P = .036). Multivariable linear regression analysis revealed that serum tPSA levels were independently associated with PAOI in patients with PE (β = .347, P = .003). Serum tPSA levels were higher in male patients with PE than those in healthy controls, but fPSA was not affected. These findings highlight that PE may elevate serum tPSA levels, and that measures of tPSA should be interpreted with caution in screening for prostate diseases in patients with PE.

Abstract
INTRODUCTION The associations among SARS-CoV-2 infection, vaccination and total serum prostate serum antigen (PSA) levels in men undergoing screening for prostate cancer are unknown. METHODS A retrospective analysis of data from a large health maintenance organization. Records of individuals aged 50 to 75 years with two serum PSA tests taken between March 2018 and November 2021 were included. Individuals with prostate cancer were excluded. Changes in PSA levels were compared between individuals who had at least 1 SARS-CoV-2 vaccination and/or infection between the two PSA tests and individuals who did not have an infection and were not vaccinated between the two PSA tests. Subgroup analyses were performed to assess the impact of the elapsed time between the event and the second PSA test on the results. RESULTS The study and control groups included 6,733 (29%) and 16 286 (71%) individuals, respectively. Although the median time between PSA tests was shorter in the study vs. the control group (440 vs. 469 days, P<.001), PSA elevation between the tests was higher in the study group (0.04 vs. 0.02, P<.001). The relative risk for PSA elevation ≥1 ng/dL was 1.22 (95% CI 1.1, 1.35). Among individuals who were vaccinated, PSA increased by 0.03 ng/dL (IQR -0.12, 0.28) and 0.09 ng/dL (IQR -0.05, 0.34) after 1 and 3 doses, respectively (P<.001). Multivariate linear regression showed that SARS-CoV-2 events (β 0.043; 95% CI 0.026-0.06) were associated with a greater risk for PSA elevation, after adjusting for age, baseline PSA and days between PSA tests. CONCLUSION SARS-CoV-2 infection and vaccinations are associated with a slight increase in PSA, with the third anti-COVID vaccine dose having a more prominent impact, but its clinical significance is unknown yet. Any significant increase in PSA must be investigated and cannot be dismissed as secondary to SARS-CoV-2 infection or vaccination.

Abstract
This study aimed to investigate the role of inflammatory processes in benign prostatic enlargement among men with elevated prostate-specific antigen (PSA) levels without a history of prostatic disease. Additionally, we aimed to examine the influence of serum zinc levels on prostate volume. We investigated the associations between systemic inflammatory markers, serum PSA, and serum zinc levels in 48 men without a history of prostatic disease, aged between 60-72 years, and 30 healthy men in the same age range. Data collection occurred between 1/2/2022 to 1/10/2022. The results are presented as mean values ± standard error (SE), and statistical significance was determined at p≤0.05. The levels of sIL-8 (P: 44.295±1.002, C: 1.404±0.2562), IL-6 (P: 7.406±0.5632, C: 4.468±0.830), CRP (P: 14.765±0.565, C: 6.267±0.538), increased significantly in patients with high PSA, while zinc levels (P: 92.305±2.8235, C: 114.565±8.861) decreased in the patient group. Regarding white blood cell (WBC) parameters, patients exhibited a significant increase in WBC total count (P: 12995.00±488.47, C: 7713.333±777.778), neutrophil % (P: 69.450±1.619, C: 51.200±1.826), lymphocyte % (P: 39.50±2.024, C: 30.867±1.268), and NLR (2.013±0.105). Conversely, there were no significant differences in eosinophil % (P: 3.450±0.4558, C: 3.267±0.5297), basophil % (P: 0.300±0.105, C: 0.267±1182), or monocyte % (P: 3.450±0.4558, C: 3.267±0.5297) between the two groups. In men without known prostatic illness, increased PSA was linked to markers of systemic inflammation. The results indicate the role of inflammatory processes in increasing the size of the prostate gland, as evidenced by the increased levels of immune markers like white blood cells and interleukins, along with the influence of zinc. Future research is required to determine how these markers relate to the development and incidence of prostate cancer.

Abstract
Background Previous epidemiological observational studies have reported an association between inflammatory bowel disease (IBD) and prostate cancer (PCa), but the causality is inconclusive. The purpose of this study was to evaluate the causality of IBD on PCa using the mendelian randomization (MR) analysis. Methods We performed a two-sample MR analysis with public genome-wide association studies (GWAS) data. Eligible instrumental variables (IVs) were selected according to the three assumptions of MR analysis. The inverse-variance weighted (IVW) method was the main method. Complementary methods included the MR-Egger regression, the Weighted Median, the Simple Mode, the Weighted Mode and MR pleiotropy residual sum and outlier (MR-PRESSO) methods. Results Genetically determined IBD did not have a causal effect on PCa (IVW P > 0.05). Additionally, there was no causal effect of Crohn's disease (CD) and ulcerative colitis (UC) on PCa in the MR analysis (IVW P > 0.05). Results of complementary methods were consistent with those of the IVW method. Conclusions This study does not support a causal association of IBD on PCa, which is in contrast to most observational studies.

Abstract
Background Prostate cancer (PCa) is one of the highest frequent malignant tumors with very complicated pathogenesis. Genes of neurodegenerative diseases can influence tumor progression. But its role in the progression of PCa remains unclear. The purpose of the present academic work was to identify significant genes with poor outcome and their underlying mechanism. Methods The GSE70768, GSE88808, and GSE134051 datasets were downloaded to screen the differentially expressed genes (DEGs). The DEG screening criteria were as follows: P < 0.05 and differential fold change |logFC| ≥ 1. The common DEGs (co-DEGs) of the three datasets were obtained by the Robust Rank Aggregation (RRA) method. Gene Ontology (GO) function annotation and Kyoto Encyclopedia of Genes and Genome (KEGG) pathway analysis were performed using R software. Protein-protein interaction (PPI) network analysis was performed for co-DEGs using STRING to screen critical genes. Differential expression and prognosis of key genes were analyzed by the online tool Gene Expression Profiling Interactive Analysis 2 (GEPIA2). The intersection gene between key genes and neurodegenerative genes was identified by constructing a Venn diagram. Results A total of 263 co-DEGs were identified from the three datasets. GO analysis showed that co-DEGs were mainly involved in muscle contraction and blood circulation regulation. The top ten key genes were ACTG2, APOE, F5, CALD1, MYH11, MYL9, MYLK, TPM1, TPM2, and CALM1. GEPIA2 analysis showed that APOE, MYH11, and MYLK differ dramatically between tumor and normal tissues. These key genes are related to disease-free survival (DFS) in PCa. APOE was the intersection gene between key genes and Alzheimer-related genes. Conclusion The neurodegenerative gene APOE may be a potential prognostic and diagnostic biomarker for PCa.

Abstract
To explore the signature function of the tumor mutational burden (TMB) and
potential biomarkers in prostate cancer (PCa), transcriptome profiles, somatic
mutation data, and clinicopathologic feature information were downloaded from
The Cancer Genome Atlas (TCGA) database. R software package was used to generate
a waterfall plot to summarize the specific mutation information and calculate
the TMB value of PCa. Least absolute shrinkage and selection operator (LASSO)
Cox regression analysis was used to select the hub genes related to the TMB from
the ImmPort network to build a risk score (RS) model to evaluate prognostic
values and plot Kaplan–Meier (K-M) curves to predict PCa patients survival. The
results showed that PCa patients with a high TMB exhibited higher infiltration
of CD8+ T cells and CD4+ T cells and better overall survival (OS) than those
with a low TMB. The anti-Mullerian hormone (AMH), baculoviral IAP
repeat-containing 5 (BIRC5), and opoid receptor kappa 1 (OPRK1) genes were three
hub genes and their copy number variation (CNV) was relatively likely to affect
the infiltration of immune cells. Moreover, PCa patients with low AMH or BIRC5
expression had a longer survival time and lower cancer recurrence, while
elevated AMH or BIRC5 expression favored PCa progression. In contrast, PCa
patients with low OPRK1 expression had poorer OS in the early stage of PCa and a
higher recurrent rate than those with high expression. Taken together, these
results suggest that the TMB may be a promising prognostic biomarker for PCa and
that AMH, OPRK1, and BIRC5 are hub genes affecting the TMB; AMH, OPRK1, and
BIRC5 could serve as potential immunotherapeutic targets for PCa treatment.

Abstract
BACKGROUND/AIM This study aimed to access the effectiveness of serum neutrophil-to-lymphocyte ratio (NLR) in patients undergoing prostate needle biopsy with a prostate specific antigen (PSA) between 4.0 and 10.0 ng/ml. PATIENTS AND METHODS A total of 633 cases were eligible. We evaluated several factors including age, PSA, PSA-density (PSAD), platelet-to-lymphocyte ratio (PLR) and NLR in the presence or absence of prostate cancer (PCa), retrospectively. We evaluated statistically the associations between each factor and pathological findings or Gleason score. RESULTS A total of 201 were evaluated in this study. Regarding the presence or absence of prostate cancer, there were statistically significant differences in age, PSA levels, PSAD, the PLR and NLR. The mean NLR value of the patients with PCa was significantly lower compared to the entire cohort. Multivariate analysis showed that age, PSAD, and NLR were independent risk factors predicting PCa. CONCLUSION For patients having a PSA between 4.0 and 10.0 ng/ml, NLR was a predicting factor of PCa prior to prostate needle biopsy and an effective biomarker and useful tool for avoiding unnecessary biopsies.

Abstract
OBJECTIVE To investigate the diagnostic efficiency of systemic immune response (SII) in prostate cancer (PCa) in patients with PSA < 10 ng/mL undergoing fusion prostate biopsy. METHODS The prospective study included patients who were planned for fusion prostate biopsy and had PSA < 10 ng/mL and a PI-RADS ≥ 3. All the patients underwent 12-core standard transrectal prostate biopsy followed targeted biopsy (combined biopsy). Based on preoperative complete blood count parameters, SII was calculated using the following formula: SII = platelet × neutrophil-to-lymphocyte ratio. Correlations between PI-RADS score, platelet, neutrophil-to-lymphocyte ratio, PSA, PSA density, SII and PCa were determined using ROC curve analysis. Optimal cut-off values were determined using the maximum Youden Index (defined as: sensitivity + specificity - 1). RESULTS The study included 508 patients with a mean age of 62.49 ± 6.86 years and a median PSA level of 7.28 (5.69-8.70) ng/mL. The overall clinically significant PCa rate was 39.4%. Although SII had no significant diagnostic value in PCa patients with low ISUP grades (grade 1 and 2) (AUC = 0.487, P = 0.622), it was revealed as a significant marker in PCa patients with an ISUP grade ≥ 3 (AUC = 0.811, P < 0.001). The cut-off value of SII was 533.0. While the combination of SII with PI-RADS score is the most effective marker, neutrophil-to-lymphocyte ratio and platelet were also revealed as effective markers in predicting ISUP grade 3-5 PCa, though not as effective as SII. CONCLUSION SII and SII combination with PI-RADS score appear to be a significant diagnostic marker in patients with high-grade PCa (ISUP grade 3-5). These values were found to be higher compared to those of patients with a benign pathology and patients with lower ISUP scores.

Abstract
PURPOSE We investigated role of neutrophil-to-lymphocyte ratio (NLR) in the diagnosis and prediction of extracapsular extension (ECE) in clinically localized prostate cancer (PCa). MATERIALS AND METHODS A total of 396 patients with clinically localized PCa who underwent open radical retropubic prostatectomy (RRP), and 260 patients with benign prostatic hyperplasia (BPH) who underwent suprapubic prostatectomy were included in the study. Preoperative NLR, prostate specific antigen (PSA), prostate specific antigen density (PSAD), free PSA, prostate volume (PV), free/total PSA (f/t PSA) in both groups, and relation of NLR with PSA, Gleason Score (GS), and pathologic stage in PCa group were investigated. Records of patients were analyzed retrospectively. RESULTS NLR, free PSA, f/t PSA, and PV were statistically higher in BHP, and PSAD was higher in PCa group. In PCa group, NLR was found to be higher in patients with PSA >10 ng/ml compared to those with less than ⩽10 ng/ml. NLR increases as the preoperative GS increases, and it was higher in pT3 patients than pT2 patients. NLR was statistically higher in those patients with positive lymph nodes than those without after RRP (p = 0.029). CONCLUSION NLR is not a sufficient biomarker in differentiating clinically localized PCa from BPH. NLR increases as preoperative GS and pathologic stage increases. Lymph node involved patients after RRP have statistically higher NLR. NLR can be an indicator of ECE and lymph-node involvement in clinically localized PCa.

Abstract
Prostate cancer (PCa) is one of the most common malignancies for males, but very little is known about its pathogenesis. This study aimed to identify novel biomarkers associated with PCa prognosis and elucidate the underlying molecular mechanism. First, The Cancer Genome Atlas (TCGA) RNA-sequencing data were utilized to identify differentially expressed genes (DEGs) between tumor and normal samples. The DEGs were then applied to construct a co-expression and mined using structure network analysis. The magenta module that was highly related to the Gleason score (r = 0.46, p = 3e-26) and tumor stage (r = 0.38, p = 2e-17) was screened. Subsequently, all genes of the magenta module underwent function annotation. From the key module, CCNA2, CKAP2L, NCAPG, and NUSAP1 were chosen as the four candidate genes. Finally, internal (TCGA) and external data sets (GSE32571, GSE70770, and GSE141551) were combined to validate and predict the value of real hub genes. The results show that the above genes are up-regulated in PCa samples, and higher expression levels show significant association with higher Gleason scores and tumor T stage. Moreover, receiver operating characteristic curve and survival analysis validate the excellent value of hub genes in PCa progression and prognosis. In addition, the protein levels of these four genes also remain higher in tumor tissues when compared with normal tissues. Gene set enrichment analysis and gene set variation analysis for a single gene reveal the close relation with cell proliferation. Meanwhile, 11 small molecular drugs that have the potential to treat PCa were also screened. In conclusion, our research identified four potential prognostic genes and several candidate molecular drugs for treating PCa.

Abstract
OBJECTIVE To investigate the diagnostic efficiency of systemic immune response (SII) in prostate cancer (PCa) in patients with PSA<10ng/ml undergoing fusion prostate biopsy. METHODS The prospective study included patients who were planned for fusion prostate biopsy and had PSA<10ng/ml and a PI-RADS≥3. All the patients underwent 12-core standard transrectal prostate biopsy followed targeted biopsy (combined biopsy). Based on preoperative complete blood count parameters, SII was calculated using the following formula: SII=platelet×neutrophil-to-lymphocyte ratio. Correlations between PI-RADS score, platelet, neutrophil-to-lymphocyte ratio, PSA, PSA density, SII and PCa were determined using ROC curve analysis. Optimal cut-off values were determined using the maximum Youden Index (defined as: sensitivity+specificity-1). RESULTS The study included 508 patients with a mean age of 62.49±6.86 years and a median PSA level of 7.28 (5.69-8.70) ng/ml. The overall clinically significant PCa rate was 39.4%. Although SII had no significant diagnostic value in PCa patients with low ISUP grades (grade 1 and 2) (AUC=0.487, P=.622), it was revealed as a significant marker in PCa patients with an ISUP grade≥3 (AUC=0.811, P<.001). The cut-off value of SII was 533.0. While the combination of SII with PI-RADS score is the most effective marker, neutrophil-to-lymphocyte ratio and platelet were also revealed as effective markers in predicting ISUP grade 3-5 PCa, though not as effective as SII. CONCLUSION SII and SII combination with PI-RADS score appear to be a significant diagnostic marker in patients with high-grade PCa (ISUP grade 3-5). These values were found to be higher compared to those of patients with a benign pathology and patients with lower ISUP scores.

Abstract
Several randomized controlled trials (RCTs) have investigated the effect of lycopene supplementation on serum levels of prostate-specific antigen (PSA) in patients with prostate cancer. However, results have been inconclusive. We systematically searched PubMed, Embase, and Scopus up to January 2020 to find RCTs investigating the effect of lycopene supplementation on serum levels of PSA in patients with non-metastatic prostate cancer. Using a random-effects model, the reported risk estimates were pooled. A total of six trials were included in the final analysis. we found no significant effect of lycopene on circulating PSA (WMD: -0.60, 95% CI: -2.01, 0.81 µg/L). However, we observed a significant reducing effect when the analysis was confined to studies that included patients with higher baseline levels of PSA (≥6.5 µg/L) (WMD: -3.74 µg/L, 95% CI: -5.15, -2.32, P < 0.001). Subgroup analysis based on the duration of intervention did not result in any significant effect. Non-linear dose-response analysis did not show any significant effects of lycopene dosage (Pnon-linearity = 0.50) and duration of the intervention (Pnon-linearity = 0.63) on serum levels of PSA. Although lycopene supplementation did not produce any reduction in PSA levels overall, a significant reducing effect was observed in patients with higher levels of baseline PSA. Due to the heterogeneity of our results, further high-quality clinical trials with long-term duration are required to determine the efficacy of lycopene in patients with non-metastatic prostate cancer.

Abstract
Backgrounds The association of neutrophil-lymphocyte ratio (NLR) and CD34 expression level with PSA level, Gleason score, and clinical stage was investigated in patients with prostate cancer. The correlation between NLR and CD34 expression was also investigated to provide evidence supporting the use of NLR for predicting the prognosis of prostate cancer patients. Methods Clinical data of 75 patients diagnosed with prostate cancer by prostate aspiration biopsy were retrospectively analyzed. The correlation between NLR, CD34 expression, and clinicopathological characteristics was analyzed using the χ2 test and one-way analysis of variance. The correlation between NLR and CD34 was determined using the Pearson coefficient. Disease free survival was estimated by Kaplan-Meier analysis. Results Both NLR and CD34 expression were significantly positively correlated with PSA, Gleason score, and clinical stage (P < 0.05 both). Patients in the NLRHigh/CD34High group were characterized by high PSA level and Gleason score and late clinical stage. NLR was positively correlated with CD34 expression (r = 0.529, P < 0.001). Conclusions Pretreatment NLR was a valuable marker of prognosis in prostate cancer. NLR is positively correlated with CD34 expression.

Abstract
Background Metabolic syndrome (MetS) and serum prostate-specific antigen (PSA) levels are correlated. To investigate the underlying effect of MetS on PSA levels, the relationship between the major pathogenic factors of MetS and serum PSA levels was studied. Methods A total of 506 ostensibly healthy men who underwent routine health check-ups were recruited to this study. We evaluated the effect of the major pathogenic factors of MetS, which included insulin resistance, a subclinical inflammatory state and sexual hormone changes, on serum PSA levels by using linear regression analysis and multivariate analysis after adjusting for age, BMI and prostate volume. Results When simultaneously adjusting for age, BMI, prostate volume and high-density lipoprotein cholesterol, serum insulin levels and SHBG levels were inversely correlated with serum PSA levels (P = 0.049 and P = 0.004, respectively), and testosterone levels were positively correlated with serum PSA levels (P = 0.039). In multivariate regression models, serum insulin levels and serum SHBG levels were significantly associated with serum PSA levels (both P < 0.001). Conclusions Among the major pathogenic factors of metabolic syndrome, insulin resistance and sexual hormone changes may be the most significant contributors to the decline in serum PSA levels.

Abstract
The pathogenic mechanisms of prostate cancer (PCa) remain to be defined. In this study, we utilized the Robust Rank Aggregation (RRA) method to integrate 10 eligible PCa microarray datasets from the GEO and identified a set of significant differentially expressed genes (DEGs) between tumor samples and normal, matched specimens. To explore potential associations between gene sets and PCa clinical features and to identify hub genes, we utilized WGCNA to construct gene co-expression networks incorporating the DEGs screened with the use of RRA. From the key module, we selected LMNB1, TK1, ZWINT, and RACGAP1 for validation. We found that these genes were up-regulated in PCa samples, and higher expression levels were associated with higher Gleason scores and tumor grades. Moreover, ROC and K-M plots indicated these genes had good diagnostic and prognostic value for PCa. On the other hand, methylation analyses suggested that the abnormal up-regulation of these four genes likely resulted from hypomethylation, while GSEA and GSVA for single hub gene revealed they all had a close association with proliferation of PCa cells. These findings provide new insight into PCa pathogenesis, and identify LMNB1, TK1, RACGAP1 and ZWINT as candidate biomarkers for diagnosis and prognosis of PCa.

Abstract
BACKGROUND MicroRNAs (miRNAs or miR-) have been linked to factors associated with aggressive prostate cancer such as biochemical recurrence and metastasis. We investigated whether circulating miRNAs in plasma could be used as diagnostic biomarkers for more aggressive prostate cancer at prostate biopsy. METHODS Men, aged 40 years and above, newly diagnosed with prostate cancer were categorized into two risk groups, low-grade (Gleason score, 6 or 7 [3 + 4] and serum prostate-specific antigen [PSA], <20 ng/mL) and high-grade (Gleason score, ≥7 (4 + 3) and serum PSA, ≥20 ng/mL) prostate cancers. The limma R package was used to compare the expression of miRNAs in plasma between the two risk groups, adjusting for age. RESULTS There were 66 men, aged 46-86 years, included: 40 men with low-grade and 26 men with high-grade prostate cancers. There were lower expressions of miR-28, miR-100, miR-942, and miR-28-3p, and higher expressions of miR-708, miR-1298, miR-886-3p, miR-374, miR-376c, miR-202, miR-128a, and miR-185 in high-grade compared to low-grade prostate cancer cases at biopsy, after adjusting for age (P < 0.05). These differences were no longer statistically significant after adjusting the P values for multiple comparisons. CONCLUSION There was no circulating miRNA associated with high-grade prostate cancer at biopsy after adjusting for age and multiple comparisons. Nevertheless, relationships between these circulating miRNAs and high-grade prostate cancer were observed, which suggest them as promising prostate cancer biomarkers. Further investigation in a larger cohort may provide insight into their diagnostic potential for aggressive prostate cancer.

Abstract
Mesh rejection after combined laparoscopic TEP and TURP. High PSA level before procedure. An abscess developed several months after operation. Might be caused by mesh erosion to viscera. Mesh evacuation and debridement had been performed. No recurrence of hernia was found after mesh evacuation.
Background Prostate hypertrophy and inguinal hernia are common health issues in men aged more than 50 years. Recently, many studies showed that prostatectomy and laparoscopic inguinal hernia repair could be performed at the same time. This report depicts mesh rejection after concomitant repair of bilateral direct inguinal hernia with TEP and TURP. Presentation of case A 66-year-old man presented with bilateral direct inguinal hernia and enlargement of the prostate. Prostate biopsy shows atypical adenomatous hyperplasia accompanied by chronic inflammatory cells. Surgery was performed with laparoscopic TEP by using mesh and TURP. The patient underwent a combination of laparoscopic TEP and TURP. A single preoperative and postoperative dose of levofloxacin was administered. The laparoscopic TEP and TURP procedures were completed with no difficulty. Hematoma at the right inguinal occurred three weeks after the procedure. Bilateral inguinal abscess and sepsis occurred at 3-month follow-up. We performed laparotomy mesh evacuation and debridement, and found no recurrence of the hernia. Discussion Combined laparoscopic TEP hernia repair and TURP are feasible procedures. Bladder erosion caused by mesh might be the cause of mesh infection. However, the elevated PSA levels in this patient can be a warning sign of chronic infection in the prostate which can lead to complications of surgery. Conclusions Elevated PSA levels can be a warning before doing a combination of TEP and TURP surgery because they can show signs of infection. However, further research is needed to ascertain the relationship between elevated PSA levels and complications of combination TEP and TURP surgery.

Abstract
BACKGROUND Over the past decades, the study of the microenvironment of cancer has supported the hypothesis between inflammation and cancer. Previous studies have demonstrated a promising value of platelet-to-lymphocyte (PLR) and neutrophil-to-lymphocyte ratio (NLR) as a systemic inflammatory response in prostate cancer. AIM To evaluate their pre-biopsy values of PLR and NLR in predicting prostate cancer. MATERIAL AND METHODS This is a diagnostic study with retrospective design. We included all benign prostatic hyperplasia (BPH) and prostate cancer (PCa) patients who underwent prostate biopsy in Adam Malik Hospital between August 2011 and August 2015. We used PSA value above 4 ng/dL as the threshold for the biopsy candidates. The relationship between pre-biopsy variables affecting the percentage of prostate cancer risk was evaluated, including age, prostate-specific antigen (PSA) level, and estimated prostate volume (EPV). The PLR and NLR were calculated from the ratio of related platelets or absolute neutrophil counts with their absolute lymphocyte counts. The values then analysed to evaluate their associations with the diagnosis of BPH and PCa. RESULTS Out of 298 patients included in this study, we defined two groups consist of 126 (42.3%) BPH and 172 PCa (57.7%) patients. Mean age for both groups are 66.36 ± 7.53 and 67.99 ± 7.48 years old (p = 0.64), respectively. There are statistically significant differences noted from both BPH and PCa groups in terms of PSA (19.28 ± 27.11 ng/dL vs 40.19 ± 49.39 ng/dL), EPV (49.39 ± 23.51 cc vs 58.10 ± 30.54 cc), PLR (160.27 ± 98.96 vs 169.55 ± 78.07), and NLR (3.57 ± 3.23 vs 4.22 ± 2.59) features of both BPH and PCa groups respectively (p < 0.05). A Receiver Operating Characteristics (ROC) analysis was performed for PLR and NLR in analysing their value in predicting prostate cancer. The Area Under the Curve (AUC) of PLR is 57.9% with a sensitivity of 56.4% and specificity of 55.6% in the cut-off point of 143 (p = 0.02). The NLR cut-off point of 3.08 gives 62.8% AUC with 64.5% sensitivity and 63.5% specificity. These AUCs were comparable with the AUC of PSA alone (68.5%). We performed logistic regression between PSA, PLR, and NLR with result in the exclusion of PLR if calculated conjunctively. Therefore, NLR has a promising performance in predicting PCa in patients with PSA above 4 ng/dL (OR = 3.2; 95%CI: 1.96-5.11). We found as many as 80 (63.5%) patients with benign biopsy results with negative NLR value in this study. CONCLUSION NLR has promising value in predicting prostate cancer. A further prospective study in validating its diagnostic value was needed.

Abstract
BACKGROUND Previous studies demonstrated the promising value of platelet-to-lymphocyte (PLR) in prostate cancer. AIM This study was conducted to evaluate its pre-biopsy values in predicting prostate cancer. METHODS We included all benign prostatic hyperplasia (BPH) and prostate cancer (PCa) patients who underwent a prostate biopsy in Adam Malik Hospital between August 11th 2011 and August 31st 2015. The relationship between pre-biopsy variables which could be affecting the percentage of prostate cancer risk was evaluated, including age, prostate-specific antigen (PSA) level, and prostate volume (EPV). The PLR was calculated from the ratio of related platelets with their absolute lymphocyte counts. The values then analysed to evaluate their associations with the diagnosis of BPH and PCa. RESULTS As many as 298 patients consisted of 126 (42.3%) BPH and 172 PCa (57.7%) patients are included in this study. Mean age for both groups are 66.36 ± 7.53 and 67.99 ± 7.48 years old (p = 0.64), respectively. There are statistically significant differences noted from PSA (19.28 ± 27.11 vs 40.19 ± 49.39), EPV (49.39 ± 23.51 vs 58.10 ± 30.54), PLR (160.27 ± 98.96 vs 169.55 ± 78.07), and NLR (3.57 ± 3.23 vs 4.22 ± 2.59) features of both groups (p < 0.05). The AUC of PLR is 57.9% with a sensitivity of 56.4% and specificity of 55.6% in the cut-off point of 143 (p = 0.02). Besides, the NLR cut-off point of 3.08 gives 62.8% AUC with 64.5% sensitivity and 63.5% specificity. We asked for permission from the preceding authors of Indonesian Prostate Cancer Risk Calculator (IPCRC) and calculated its value from 98 randomised patients consist of 45 (45.92%) BPH and 53 (54.08%) PCa. We found a comparable value between PLR/NLR with IPCRC in predicting prostate cancer (AUC of 67.6%, 75.3%, and 68.4%, respectively) with a statistically significant difference of all value in both groups (p < 0.05). CONCLUSIONS PLR gives promising value in predicting prostate cancer in suspected patients. We suggest a further prospective study to validate its diagnostic values so it can be used as applicable routine calculation.

Abstract
Background Pretreatment inflammatory factors, including neutrophil, lymphocyte, platelet and monocyte counts as well as the ratios between them such as neutrophil–lymphocyte ratio (NLR), platelet–lymphocyte ratio (PLR) and lymphocyte–monocyte ratio (LMR) have been suggested as potential prognostic predictors for patients with prostate cancer (PCa). However, the prognostic effects remain controversial. Therefore, the goal of this study was evaluate the prognostic values of these markers for PCa patients using a meta-analysis. Methods Potentially relevant publications in PubMed and Cochrane Library were searched. Pooled hazard ratio (HR) with 95% confidence interval (CI) for overall survival (OS), cancer-specific survival (CSS), progression-free survival (PFS), recurrence free survival (RFS) and distant metastases-free survival (DMFS) were determined using a fixed or random effects model by STATA 13.0 software. Results Thirty-two studies involving 21,949 participants were included. Our pooled results demonstrated that a high pretreatment NLR (HR = 1.55, 95% CI 1.37–1.76), PLR (HR = 1.72; 95% CI 1.36–2.18), neutrophil (HR = 1.10; 95% CI 1.03–1.18 and monocyte counts (HR = 2.25; 95% CI 1.67–3.05) predicted inferior OS, while elevated pretreatment LMR (HR = 2.27; 95% CI 1.76–2.94) was correlated with favorable OS. Furthermore, the higher NLR (HR = 1.62; 95% CI 1.29–2.04) and monocyte counts (HR = 1.75; 95% CI 1.36–2.25), but lower LMR predicted worse PFS (HR = 2.18; 95% CI 1.58–3.02); poor RFS was only associated with NLR (HR = 1.12; 95% CI 1.04–1.20). The subgroup analysis showed that the higher NLR may be a predictive factor for OS only in patients with mCRPC and undergoing chemotherapy; while the higher PLR was only significantly associated with OS in localized PCa regardless of treatment. Conclusion This meta-analysis reveals that pretreatment NLR, PLR, LMR, neutrophil, and monocyte counts may be effective predictive biomarkers for prognosis in patients with PCa.

Abstract
BACKGROUND There are limited data examining the risk of prostate cancer (PCa) in patients with inflammatory bowel disease (IBD). OBJECTIVE To compare the incidence of PCa between men with and those without IBD. DESIGN, SETTING, AND PARTICIPANTS This was a retrospective, matched-cohort study involving a single academic medical center and conducted from 1996 to 2017. Male patients with IBD (cases=1033) were randomly matched 1:9 by age and race to men without IBD (controls=9306). All patients had undergone at least one prostate-specific antigen (PSA) screening test. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Kaplan-Meier and multivariable Cox proportional hazard models, stratified by age and race, evaluated the relationship between IBD and the incidence of any PCa and clinically significant PCa (Gleason grade group ≥2). A mixed-effect regression model assessed the association of IBD with PSA level. RESULTS AND LIMITATIONS PCa incidence at 10yr was 4.4% among men with IBD and 0.65% among controls (hazard ratio [HR] 4.84 [3.34-7.02] [3.19-6.69], p<0.001). Clinically significant PCa incidence at 10yr was 2.4% for men with IBD and 0.42% for controls (HR 4.04 [2.52-6.48], p<0.001). After approximately age 60, PSA values were higher among patients with IBD (fixed-effect interaction of age and patient group: p=0.004). Results are limited by the retrospective nature of the analysis and lack of external validity. CONCLUSIONS Men with IBD had higher rates of clinically significant PCa when compared with age- and race-matched controls. PATIENT SUMMARY This study of over 10000 men treated at a large medical center suggests that men with inflammatory bowel disease may be at a higher risk of prostate cancer than the general population.

Abstract
BACKGROUND: It is apparent that prostate cancer has harmful effects on the erythrocytes, leucocytes, and platelets. In addition, it has been suggested that the toxic granules in neutrophils lead to inflammation in the cancerous tissues besides the activation of monocytes, so in this study we aimed to evaluate the blood neutrophil count besides the neutrophil-to-lymphocyte ratio as a predictive factor for prostate biopsy results and their relationship with prostate cancer grade in patients undergoing biopsy of the prostate. METHODS: For all men with irritative lower urinary tract symptoms visiting Hasheminezhad Hospital from January to July 2015, in case of having a suspicious digital rectal examination or aged above 40 years, prostate-specific antigen was requested and in case of abnormal results, they underwent prostate biopsy. In order to examine the study hypothesis, the blood neutrophil count and the neutrophil-to-lymphocyte ratio were measured and compared with the abnormal prostate-specific antigen results and suspicious digital rectal examination. RESULTS: Among the 500 referred samples for biopsy, 352 (70.4%) had a negative biopsy result, while it was positive in the other 148 (29.6). The mean neutrophil count showed no statistical difference regarding the biopsy results (p = 0.381). When measuring the neutrophil-to-lymphocyte ratio again with biopsy results, no statistically significant difference was obtained based on the biopsy results (p = 0.112). CONCLUSION: Neutrophil count and neutrophil-to-lymphocyte ratio cannot be predictive factors for positive prostate cancer biopsy.

Abstract
Like other cancer diseases, prostate cancer (PC) is caused by the accumulation of genetic alterations in the cells that drives malignant growth. These alterations are revealed by gene profiling and copy number alteration (CNA) analysis. Moreover, recent evidence suggests that also microRNAs have an important role in PC development. Despite efforts to profile PC, the alterations (gene, CNA, and miRNA) and biological processes that correlate with disease development and progression remain partially elusive. Many gene signatures proposed as diagnostic or prognostic tools in cancer poorly overlap. The identification of co-expressed genes, that are functionally related, can identify a core network of genes associated with PC with a better reproducibility. By combining different approaches, including the integration of mRNA expression profiles, CNAs, and miRNA expression levels, we identified a gene signature of four genes overlapping with other published gene signatures and able to distinguish, in silico, high Gleason-scored PC from normal human tissue, which was further enriched to 19 genes by gene co-expression analysis. From the analysis of miRNAs possibly regulating this network, we found that hsa-miR-153 was highly connected to the genes in the network. Our results identify a four-gene signature with diagnostic and prognostic value in PC and suggest an interesting gene network that could play a key regulatory role in PC development and progression. Furthermore, hsa-miR-153, controlling this network, could be a potential biomarker for theranostics in high Gleason-scored PC.

Abstract
BACKGROUND AND OBJECTIVE Prostate cancer is considered as one of the most common malignancies in males. Despite the decreasing trend during the past decade, the incidence continues to rise in adolescents worldwide. Recently, new emerging technologies beside TRUS-guided prostate biopsy were introduced and showed high potential in the diagnosis of prostate cancer. The current study aimed at investigating the role of blood cell count and its prognostic value on pathologic findings. METHODS The current prospective analysis was conducted on patients with abnormality from January 2013 to January 2016. A total of 168 CBC tests including absolute Neutrophil and lymphocyte counts were performed on males at the Department of Urology, Razi University Hospital (Guilan, Iran). Of these, all males had both CBCs and free:total (F/T) prostate-specific antigen (PSA) ratio. RESULTS Average age of patients was 63.5±7. It was observed that Neutrophil count and Neutrophil percentage was not significantly different among the groups with different pathologies. In comparison to biopsy findings none of the cell count had suitable specificity and sensitivity. In the multivariate analysis to predict malignancy, only age (B=0.1, S.E=0.04, EXP [B]) =1.1 and sig=0.00) and PSA level (B=0.1, S.E=0.04, EXP [B]) =1.1 and sig=0.00) were significant. CONCLUSIONS In comparison to biopsy findings, none of the cell counts (absolute or percent) had suitable specificity and sensitivity, and the cell count and percentage before biopsy were not different among the groups with different pathologies. Powerful and long-term studies are required to evaluate prognostic values of cell count on adenocarcinoma.

Abstract
OBJECTIVE Serum prostate-specific antigen (PSA) may be elevated in healthy men with systemic inflammation. We aimed to investigate the association between systemic inflammation markers and serum PSA in a healthy Korean population. MATERIAL AND METHODS A cohort of 20,151 healthy native Korean men without prostate disease between the ages of 40 and 65 years who underwent medical checkups were studied from January 2007 to December 2013. Serum total PSA and serum C-reactive protein concentrations, neutrophil, lymphocyte, and platelet counts were determined. The neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were calculated. We checked the correlation between systemic inflammation markers and PSA. RESULTS Data obtained from 18,800 healthy men were analyzed. The mean age of the study subjects was 50.72±7.62 years and the mean NLR was 1.764±0.804. Correlation analysis after adjustment for age and body mass index (BMI) revealed that neutrophil count (coefficient = 0.028, p value <0.001), and NLR (coefficient = 0.027, p value <0.001) correlated with PSA. Multivariate analysis using the full model revealed that age, neutrophil count and NLR were positively correlated with PSA (p<0.001, 0.001, and 0.043 respectively). Multivariate analysis using a stepwise model revealed that age, neutrophil count and NLR were positively correlated with PSA (p<0.001, 0.001, and 0.040, respectively) and BMI was negatively correlated with PSA (p<0.001). CONCLUSION Systemic inflammation markers are useful with a serum PSA in a healthy Korean population. NLR in particular is significantly associated with serum PSA.

Abstract
BACKGROUND The Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC), the largest component of the European Randomized Study of Screening for Prostate Cancer (ERSPC), showed a smaller, nonsignificant reduction in prostate cancer-specific mortality by systematic prostate-specific antigen (PSA)-based screening compared with the overall ERSPC results. Nonsteroidal anti-inflammatory drugs (NSAIDs) reduce inflammation and also PSA elevations due to intraprostatic inflammation. OBJECTIVE To explore whether NSAID usage modifies the effects of PSA-based screening on prostate cancer incidence and mortality. DESIGN, SETTING, AND PARTICIPANTS A cohort of 78 165 men from the FinRSPC were linked to a comprehensive national prescription database to obtain information on NSAID reimbursements prior to screening. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Prostate cancer risk and mortality were compared between the FinRSPC screening arm and the control arm among NSAID users and nonusers using an age-adjusted Cox regression model. RESULTS AND LIMITATIONS Screening increased the detection of Gleason 6 (hazard ratio [HR] 1.59, 95% confidence interval [CI] 1.47-1.72 and HR 1.39, 95% CI 1.26-1.54) and localized prostate tumors (HR 1.25, 95% CI 1.18-1.32 and HR 1.11, 95% CI 1.03-1.20) more among baseline NSAID nonusers than among users, respectively (p for interaction <0.04 for both). This difference was observed in all three screening rounds. Detection of metastatic prostate cancer was similar in both NSAID users and nonusers. Screening decreased prostate cancer mortality among men using NSAIDs at FinRSPC randomization (HR 0.66, 95% CI 0.49-0.90) but not among nonusers (HR 0.95, 95% CI 0.81-1.12); p for interaction=0.04. CONCLUSIONS Screening detected fewer well-differentiated localized tumors among NSAID users than among nonusers. This suggests that PSA screening may cause less overdiagnosis within this subgroup, whereas mortality benefit may be greater among NSAID users. PATIENT SUMMARY Prostate cancer screening causes less overdiagnosis of well-differentiated localized prostate tumors among men who use nonsteroidal anti-inflammatory drugs.

Abstract
Background The neutrophil-to-lymphocyte ratio (NLR) is reported as a biomarker for some solid malignant diseases. Thus far, however, no reports of the relationship between the NLR and adrenal tumors have been published. We analyzed the utility of the preoperative NLR as a biomarker for predicting the prognosis or diagnosis of malignant disease. Methods A total of 59 patients with adrenal tumors (13 cases of malignant disease and 46 with benign disease) were analyzed in this study from February 2004 to June 2015 at our institute. The NLR was obtained just before adrenalectomy. The diagnosis of adrenal tumor was confirmed by a pathological examination of surgical specimens. Results The NLR in malignant adrenal tumor specimens was significantly higher than in non-malignant specimens (p = 0.028). Adrenocortical carcinoma (ACC) showed the highest NLR among all adrenal tumors. In ACC, the higher NLR group (NLR ≥ 5) showed a significantly poorer overall survival than the lower NLR group (NLR < 5) (p = 0.032). Conclusions In adrenal tumors, a higher NLR indicates a higher incidence of malignancy. The NLR might be a new biomarker for predicting the prognosis of adrenal tumor patients.

Abstract
The aim of this study was to determine whether the neutrophil-to-lymphocyte ratio (NLR), a measure of the systemic inflammatory response is associated with the overall prostate cancer detection rate in men who underwent contemporary multi (≥12)-core transrectal ultrasound (TRUS) biopsy. We reviewed the records of 3913 patients with initial prostate-specific antigen (PSA) levels ranging from 4 to 10 ng ml−1 who underwent TRUS-guided prostate biopsy between April 2006 and May 2014. NLR was calculated by prebiopsy neutrophil and lymphocyte counts. We excluded patients who had evidence of acute prostatitis, a history of prostate surgery, and any systemic inflammatory disease. A multivariate logistic regression model was used to analyze prostate cancer detection. After adjusting for confounding factors, predictive values were determined according to the receiver operating characteristic-derived area under the curve, both including and excluding the NLR variable. In univariate analyses, NLR was a significant predictor of prostate cancer detection (P < 0.001). In multivariate analyses, a higher NLR was significantly associated with prostate cancer detection after adjusting for other factors (OR = 1.372, P = 0.038). The addition of NLR increased the accuracy from 0.712 to 0.725 (P = 0.005) in the multivariate model for prostate cancer detection. NLR may be a potentially useful clinical marker in the detection of prostate cancer among men with a PSA level in the 4–10 ng ml−1 range. These findings are derived from a retrospective analysis and should be validated in larger populations through prospective studies.

Abstract
BACKGROUND We investigated the association of prostate-specific antigen (PSA) with leukocyte telomere length, which may be altered in preclinical prostate malignancies. METHODS This study was based on the 2001-2002 U.S. National Health and Nutrition Examination Survey (NHANES). A subsample of 1,127 men aged 40-85 years without prior history of prostate cancer who provided informed consent and blood samples were selected. Leukocyte telomere length (LTL) relative to standard DNA reference (T/S ratio) was quantified by polymerase chain reaction (PCR). Survey-weighted multivariable linear regression was performed to examine T/S ratio across quintiles of total and free PSA and free-to-total PSA ratio (%fPSA). A sensitivity analysis was performed by excluding men dying from prostate cancer during follow-up through to December 31, 2006. Stratification analyses were carried out to assess any effect modification by age group, race, body mass index (BMI), and levels of C-reactive protein (CRP), a marker of inflammation. RESULTS Higher total PSA levels were associated to longer LTL, with approximately 8% increase in log-transformed T/S ratio (95% confidence interval [CI]: 2-13%) among men in the highest quintile of total PSA compared to the lowest in the fully adjusted model (Ptrend = 0.01). No significant association was found for free PSA or %fPSA, although nonlinearity between all PSA measures and T/S ratio was indicated. Similar results were found after excluding men who died from prostate cancer during follow-up. We also found the associations between total PSA and T/S ratio to be strongest among non-Hispanic blacks, non-obese men (BMI <30 kg/m2 ), and those with low CRP. However, a significant interaction was only found between total PSA and race/ethnicity (Pinteraction = 0.01). CONCLUSION Total PSA levels were strongly associated to LTL, particularly among non-Hispanic blacks. Our findings support a potential link between PSA and specific mechanisms contributing to prostate cancer development. Prostate 77:22-32, 2017. © 2016 Wiley Periodicals, Inc.

Abstract
INTRODUCTION This study was aimed to determine the association between PSA levels and biomarkers of subclinical systemic inflammation based on data from 119 middle-aged healthy men from the general population. MATERIALS AND METHODS Serum levels of PSA and biomarkers of systemic inflammation (CRP and fibrinogen) were measured. Demographic data were also collected. Subjects were divided into two groups according to PSA levels; < 2 ng/ml and ≥ 2 ng/ml. RESULTS The mean (SD) age of men was 55 ± 4.0 years. We found a positive significant correlation between PSA and fibrinogen levels (r = 0.20, p = 0.04), and between CRP and fibrinogen levels (r = 0.60, p = 0.01). On the other hand, no significant correlation between PSA and CRP levels was found. Men with PSA values ≥ 2 ng/ml had significantly higher levels of fibrinogen as compared to those with PSA < 2 ng/ml (2.9 ng/ml vs. 2.4 ng/ml, p = 0.01). In a multivariate regression analysis model adjusted for the age of subjects, BMI, marital status, smoking, snuff, and alcohol intake with serum levels of PSA as a dependent variable, serum level of fibrinogen predicted higher PSA-values (odds ratio = 3.30, 95% CI = 1.05-10.20, p = 0.042). CONCLUSIONS The present results indicate that serum fibrinogen is a biomarker of subclinical systemic inflammation associated with PSA elevation among middle-aged healthy men from the general population.

Neutrophil-to-lymphocyte ratio predicts prostatic carcinoma in men undergoing needle biopsy. Oncotarget 2016; 6:32169-76.

Abstract
Neutrophil-to-lymphocyte ratio (NLR), a simple marker of systemic inflammatory response, has been demonstrated as an independent prognosticator for some solid malignancies, including prostate cancer. In the present study, we evaluated the role of NLR in men who underwent prostate needle biopsy for their initial diagnosis of prostatic carcinoma. Both complete blood counts and free/total (F/T) prostate-specific antigen (PSA) ratio were examined in a total of 3,011 men in our institution. Of these, 1,207 had a PSA level between 4 and 10 ng/mL, and 357 of 810 who subsequently underwent prostate needle biopsy were found to have prostatic adenocarcinoma. NLR value was significantly higher in men with PSA of ≥ 20 ng/mL than in those with PSA of < 20 ng/mL (p < 0.001). NLR was also significantly higher in men with positive biopsy than in those with negative biopsy (p < 0.001). Using NLR cut-off point of 2.40 determined by the AUROC curve, positive/negative predictive values of NLR alone and NLR combined with F/T PSA ratio (cut-off: 0.15) were 56.6%/60.8% and 80.7%/60.1%, respectively. Multivariate analysis revealed that not only F/T PSA ratio (HR = 3.13) but also NLR (HR = 2.21) was an independent risk factor for prostate cancer. NLR is thus likely elevated in patients with prostate cancer. Accordingly, NLR, with or without combination with F/T PSA ratio, may function as a new biomarker to predict prostate cancer in men undergoing prostate needle biopsy.

Abstract
The baseline value of neutrophil to lymphocyte ratio (NLR) has been found to be prognostic in patients with metastatic castration resistant prostate cancer (CRPC). We evaluated the impact of baseline NLR and its change in patients receiving enzalutamide. We included consecutive metastatic CRPC patients treated with enzalutamide after docetaxel and studies the change of NLR (>3 vs ≤3) after week 4 and 12 weeks. Progression-free survival (PFS), overall survival (OS) and their 95% Confidence Intervals (95% CI) were estimated by the Kaplan-Meier method and compared with the log-rank test. The impact of NLR on PFS and OS was evaluated by Cox regression analyses and on prostate-specific antigen response rates (PSA RR; PSA decline >50%) were evaluated by binary logistic regression. Data collected on 193 patients from 9 centers were evaluated. Median age was 73.1 years (range, 42.8–90.7). The median baseline NLR was 3.2. The median PFS was 3.2 months (95% CI = 2.7–4.2) in patients with baseline NLR >3 and 7.4 months (95% CI = 5.5–9.7) in those with NLR ≤3, p < 0.0001. The median OS was 10.4 months (95% CI = 6.5–14.9) in patients with baseline NLR >3 and 16.9 months (95% CI = 11.2–20.9) in those with baseline NLR ≤3, p < 0.0001. In multivariate analysis, changes in NLR at 4 weeks were significant predictors of both PFS [hazard ratio (HR) 1.24, 95% confidence interval (95% CI) 1.07–1.42, p = 0.003, and OS (HR 1.29, 95% CI 1.10–1.51, p = 0.001. A persistent NLR >3 during treatment with enzalutamide seems to have both prognostic and predictive value in CRPC patients.

Abstract
PURPOSE To predict prostatic carcinoma using a logistic regression model on prebiopsy peripheral blood samples. MATERIALS AND METHODS Data of a total of 873 patients who consulted Urology Outpatient Clinics of Fatih Sultan Mehmet Training and Research Hospital between February 2008 and April 2014 scheduled for prostate biopsy were screened retrospectively. PSA levels, prostate volumes, prebiopsy whole blood cell counts, neutrophil and platelet counts, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), biopsy results and Gleason scores in patients who had established diagnosis of prostate cancer (PCa) were evaluated. RESULTS This study was performed on a total of 873 cases, with an age range 48-76 years, divided into three groups as for biopsy results. with diagnoses of benign prostatic hyperplasia (BPH) (n=304, 34.8 %), PCa (n=265, 30.4%) and histological prostatitis (n=304; 34.8%). Intra- and intergroup comparative evaluations were performed. White blood cell and neutrophil counts in the histological prostatitis group were significantly higher than those of the BPH and PCa groups (p=0.001; p=0.004; p<0.01). A statistically significant intergroup difference was found for PLR (p=0.041; p<0.05) but not lymphocyte count (p>0.05). According to pairwise comparisons, PLR were significantly higher in the PCa group relative to BPH group (p=0.018, p<0.05, respectively). Though not statistically significant, higher PLR in cases with PCa in comparison with the prostatitis group was remarkable (p=0.067, and p>0.05, respectively). CONCLUSIONS Meta-analyses showed that in patients with PSA levels over 4 ng/ml, positive predictive value of PSA is only 25 percent. Therefore, novel markers which can both detect clinically significant prostate cancer, and also prevent unnecessary biopsies are needed. Relevant to this issue in addition to PSA density, velocity, and PCA3, various markers have been analyzed. In the present study, PLR were found to be the additional predictor of prostatic carcinoma.

Abstract
An unprecedented advance has been seen in castration-resistant prostate cancer (CRPC) treatments in the past few years. With a number of novel agents were approved, there is a pressing need to develop improved prognostic biomarkers to facilitate the personalised selection and sequencing of these novel agents. Emerging evidence indicates that the neutrophil-to-lymphocyte ratio (NLR) is associated with poorer survival in patients with prostate cancer (PCa). However, the importance of the NLR for the prediction of the PSA response (PSARS) and biochemical recurrence (BCR) has been largely neglected. Here, we conducted a systematic review and meta-analysis to evaluate the prognostic value of the NLR for the PSARS, BCR, and survival in PCa. A systematic database search was performed using Embase, PubMed, the Cochrane Library, and the China National Knowledge Infrastructure (CNKI). A meta-analysis was performed by pooling hazard ratios (HRs), odds ratios (ORs) and the corresponding 95% confidence intervals (CIs). A total of 22 studies were included in the meta-analysis. Our results suggest that an elevated NLR predicts a lower PSARS rate (OR = 1.69, 95% CI: 1.40–1.98) and a higher possibility of BCR (HR = 1.12, 95% CI: 1.02–1.21). Additionally, we confirmed that an elevated NLR was a prognostic predictor of shorter overall survival (OS) in both metastatic castration-resistant PCa (mCRPC) (HR = 1.45, 95% CI: 1.32–1.59) and localized PCa (LPC) (HR = 1.12, 95% CI: 1.01–1.23) and that it predicted worse progression-free survival (PFS) in CRPC (HR = 1.42, 95% CI: 1.23–1.61) and poorer recurrence-free survival (RFS) (HR = 1.38, 95%CI: 1.01–1.75) in LPC. Our results suggest that an elevated NLR might be employed as a prognostic marker of biochemical changes and prognosis to facilitate risk stratification and decision making for individual treatment of PCa patients. The potential mechanisms underlying these associations and future research directions are also discussed.

Lack of an Association between Neutrophil-to-Lymphocyte Ratio and PSA Failure of Prostate Cancer Patients Who Underwent Radical Prostatectomy. BIOMED RESEARCH INTERNATIONAL 2016; 2016:6197353.

Abstract
Introduction. The neutrophil-to-lymphocyte ratio (NLR), which can be easily calculated from routine complete blood counts of the peripheral blood, has been suggested to serve as a prognostic factor for some solid malignancies. In the present study, we aimed to determine the relationship between NLR in prostate cancer patients undergoing radical prostatectomy (RP) and their prognosis. Materials and Methods. We assessed NLR in 73 men (patients) who received RP for their prostate cancer. We also performed immunohistochemistry for CD8 and CD66b in a separate set of RP specimens. Results. The median NLR in the 73 patients was 1.85. There were no significant correlations of NLR with tumor grade (p = 0.834), pathological T stage (p = 0.082), lymph node metastasis (p = 0.062), or resection margin status (p = 0.772). Based on the area under the receiver operator characteristic curve (AUROC) to predict biochemical recurrence after RP, potential NLR cut-off point was determined to be 2.88 or 3.88. However, both of these cut-off points did not precisely predict the prognosis. There were no statistically significant differences in the number of CD66b-positive neutrophils or CD8-positive lymphocytes between stromal tissues adjacent to cancer glands and stromal tissues away from cancer glands and between different grades or stages of tumors. Conclusions. There was no association between NLR and biochemical failure after prostatectomy.

Pretreatment plasma fibrinogen as an independent prognostic indicator of prostate cancer patients treated with androgen deprivation therapy. Prostate Cancer Prostatic Dis 2016; 19:209-15. [PMID: 26951714 DOI: 10.1038/pcan.2016.6] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2015] [Revised: 01/13/2016] [Accepted: 01/19/2016] [Indexed: 12/17/2022]
Abstract
BACKGROUND Hyperfibrinogen is thought to be associated with a higher risk of invasion and metastasis, as well as a worse outcome for multiple types of cancer. However, the prognostic significance of plasma fibrinogen has not been investigated in prostate cancer with hormonal therapy. The objective of this study was to evaluate its roles in prostate cancer patients treated with androgen deprivation therapy (ADT). METHODS A total of 290 patients who underwent ADT as first-line therapy for prostate cancer were retrospectively analyzed. The fibrinogen level was measured at the time of diagnosis. Patients were categorized using a cutoff point of 3.225 g l(-1) according to a calculation by the receiver operating curve analysis. Correlations between the fibrinogen and clinical characteristics were analyzed. Meanwhile, univariable and multivariable cox regression analyses were performed to determine the associations of fibrinogen with progression-free survival (PFS), cancer-specific survival (CSS) and overall survival (OS). Prognostic accuracy was evaluated with the Harrell concordance index. RESULTS Compared with patients with a lower fibrinogen level (<3.225 g l(-1)), patients with a higher fibrinogen level were more likely to have higher PSA, Gleason score, risk stratification and incidence of metastasis (P<0.05). Multivariable analyses identified hyperfibrinogen as an independent prognostic factor for PFS (hazard ratio (HR)=2.000, P<0.001), CSS (HR=2.209, P=0.006) and OS (HR=1.965, P=0.009). The final models built by the addition of fibrinogen improved predictive accuracy (c-index: 0.750, 0.799 and 0.767) for PFS, CSS and OS compared with the clinicopathological base models (c-index: 0.730, 0.778 and 0.746), which included Gleason score and metastasis. CONCLUSIONS The pretreatment plasma fibrinogen level was associated with tumor progression and might have a significant role in the prognosis of the prostate cancer patients treated with ADT. Thus, we recommend adding fibrinogen to traditional prognostic model, which may improve its predictive accuracy.

Abstract
Background The neutrophil-to-lymphocyte ratio (NLR), a simple marker of the systemic inflammatory response in critical care patients, has been suggested as an independent prognostic factor for several solid malignancies. We investigated the utility of pretreatment NLR as a prognosticator in patients who presented with metastatic prostate cancer. Methods We first investigated the correlation between NLR and prostate-specific antigen (PSA) levels in 1464 men who had both tests and were found to have prostate cancer on their biopsies at our institution from 1999 to 2015. We then assessed the relationship between pretreatment NLR and the prognosis in 48 patients who were diagnosed with prostate cancer metastasized to the lymph node and/or bone. Results The NLR value was significantly elevated in men with higher PSA than in those with lower PSA (p < 0.001). In patients with metastatic prostate cancer, NLR (cut-off point of 3.37 determined by the AUROC curve) was correlated with both cancer-specific (p = 0.018) and overall (p = 0.008) survivals. Conclusions Pretreatment NLR may function as a new biomarker that precisely predicts the prognosis in patients with metastatic prostate cancer.

Abstract
INTRODUCTION We evaluate the role of NLR prior to prostate biopsy to predict biopsy histology and Gleason score in patients with prostate cancer. METHODS In this retrospective study, we evaluated data of patients underwent prostate biopsy between May 2005 and March 2015. We collected the following data: age, prostate-specific antigen (PSA), biopsy histology, Gleason score (GS) in prostate cancer patients, neutrophil counts, and lymphocyte counts. Patients were grouped as benign prostatic hyperplasia (BPH), prostate cancer, and prostatitis. The Chi square test was used to compare categorical variables and analysis of variance (ANOVA) was applied for continuous variables. RESULTS Data of 1836 patients were investigated. The mean age, total PSA and neutrophil-lymphocyte ratio (NLR) of the population were 66.8 ± 8.17 years, 9.38 ± 4.7 ng/dL, and 3.11 ± 1.71, respectively. Patients were divided as follows: 625 in the group with BPH history, 600 in the prostatitis group, and 611 in the prostate cancer histology group. The mean NLR of the prostatitis group was higher compared to the prostate cancer and BPH groups (p = 0.0001). The mean NLR of the prostate cancer group was significantly higher compared to the BPH group (p = 0.002). The GS 8-10 group had a significantly higher mean NLR compared to GS 5-6 (3.64 vs. 2.54, p = 0.0001) and GS 7 (3.64 vs. 2.58, p = 0.0001) patients. CONCLUSIONS NLR was found to differ with regard to histology of prostate biopsy and higher GS was associated with higher NLR in patients with prostate cancer. However prostatitis prevents the use of NLR in predicting prostate cancer before a prostate biopsy. Also, the retrospective nature and lack of multivariate analysis in this study somewhat limits the relevance of these results.

The association of an elevated plasma fibrinogen level with cancer-specific and overall survival in prostate cancer patients. World J Urol 2014; 33:1467-73. [PMID: 25475065 DOI: 10.1007/s00345-014-1459-2] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2014] [Accepted: 11/28/2014] [Indexed: 01/27/2023] Open
Abstract
PURPOSE Fibrinogen plays an important role in the pathophysiology of tumour cell invasion and metastases. In recent studies, an elevated plasma fibrinogen level has been associated with poor prognosis in different types of cancer. The present study was performed to analyse the prognostic impact of an elevated fibrinogen level in prostate cancer patients. METHODS We evaluated data from 268 prostate cancer patients who underwent 3D conformal radiotherapy between 1999 and 2006 at a single tertiary academic center. Cancer-specific survival (CSS), overall survival (OS), and clinical disease-free survival (DFS) were assessed using the Kaplan-Meier method. Univariable and multivariable Cox regression models were performed for each endpoint. RESULTS Applying receiver operating characteristics (ROC) curve analysis, the optimal cut-off level for the plasma fibrinogen level was 530 mg dl(-1), respectively. Univariable (HR 3.638, 95 % CI 1.15-11.47, p = 0.027) and multivariable analyses (HR 3.964, 95 % CI 1.06-14.87, p = 0.041) revealed a significant correlation between increased plasma fibrinogen and CSS. Univariable analysis also showed a significant association between the elevated plasma fibrinogen level and decreased OS (HR 3.242, 95 % CI 1.53-6.89, p = 0.002), that remained significant in multivariable analysis (HR 3.215, 95 % CI 1.44-7.19, p = 0.004). No significant associations were found for clinical DFS. CONCLUSION Although our data show a significant association between an elevated plasma fibrinogen level and poor prostate cancer prognosis, they have to be interpreted cautiously. Limitations of the present study are caused by its retrospective design, the limited accuracy obtained using ROC curve analysis, and potential confounding factors like cardiovascular disease and inflammatory diseases that have not been accounted for.

[PMID: 25054003 DOI: 10.3892/br.2014.300] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2014] [Accepted: 06/02/2014] [Indexed: 11/05/2022] Open
Abstract
The aim of the present study was to determine whether the interleukin-6 (IL-6) (-174 G/C) gene polymorphism correlates with prostate cancer. A meta-analysis based on former studies was conducted and the results suggest that there was no significant association between IL-6 (-174 G/C) polymorphism and the prostate cancer risk. However, a recent study published in January 2014 showed that the GG genotype may be associated with an increased risk of prostate cancer in Caucasian subjects, whereas the CC genotype was associated with an increased risk in the African-American subjects, which was inconsistent with former studies. Databases, including PubMed, Embase, Web of Science, the Cochrane Library, Chinese Biomedical Literature Database and Wanfang database, were searched between January 1994 and March 2014 to determine the eligible IL-6 (-174 G/C) polymorphism studies and the susceptibility of the prostate cancer risk. A total of 11 studies with 10,745 cases and 13,473 controls fulfilled the inclusion criteria subsequent to assessment by two investigators. The pooled odds ratio (OR) with 95% confidence interval (95% CI) was calculated to examine the associations, and subgroup analyses were performed according to the ethnicity. Overall, no significant association was found between the IL-6 (-174 G/C) polymorphism and prostate cancer risk, whereas the subgroup analysis suggested that the association between the IL-6 (-174 G/C) polymorphism and prostate cancer was slightly significant under the homozygote (CC vs. GG: OR, 3.43; 95% CI, 1.01-11.71; P=0.049) and recessive models (CC vs. GG/GC OR, 3.51; 95% CI, 1.04-11.82; P=0.042) in African-American patients. However, no significant association was found in the Caucasian, Asian or mixed populations under the five genetic models by stratifying studies for ethnicity. In conclusion, the present study suggested that there was no significant association between the IL-6 (-174 G/C) polymorphism and prostate cancer risk in Caucasian and Asian patients, whereas the CC genotype may be associated with an increased risk in the African-American patients.
