Objective: To evaluate the predictive role of the inflammatory parameters, especially monocyte-to-lymphocyte (MLR) ratio, on the diagnosis of prostate cancer (PCa). Material and Methods: The data of patients undergoing prostate biopsy between July 2015 and July 2019 were retrospectively analyzed. The data including age, PSA, neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte (PLR), MLR and histopathologies were recorded. Patients were grouped as benign prostatic hyperplasia (BPH), PCa and prostatitis according to PBx histopathology and all variables were analyzed. Results: Pathology results of 338 patients are as follows: 124 (36.7%) BPH, 132 (39.1%) PCa and 82 (24.3%) prostatitis. Patients with PCa were older and had higher serum PSA, PLR, NLR and MLR values compared to non-PCa patients. In the comparison made by excluding metastatic patients, only serum PSA and MLR values remained statistically high. All three parameters had significant AUC to predict PCa in entire-cohort, but only the MLR had significant AUC to predict PCa in the cohort which metastatic patients were excluded. Multivariate logistic regression analysis revealed that only serum PSA and MLR values were significant independent predictors of PCa. Conclusion: In our study, it was observed that only MLR among all inflammatory markers found to be high in PCa patients continued to be high in nonmetastatic PCa patients. In the multivariate regression model created from age, PSA and MLR, MLR was found to be a significant independent predictor of PCa like PSA. MLR can be used as an inexpensive, easily accessible and applicable new marker to predict PCa. Keywords: inflammatory markers, monocyte-to-lymphocyte ratio, prostate biopsy, prostate cancer

Background: circulating levels of lymphocytes, platelets and neutrophils have been identified as factors related to unfavorable clinical outcome for many solid tumors. The aim of this cohort study is to evaluate and validate the use of the Prostatic Systemic Inflammatory Markers (PSIM) score in predicting and improving the detection of clinically significant prostate cancer (csPCa) in men undergoing robotic radical prostatectomy for low-risk prostate cancer who met the inclusion criteria for active surveillance. Methods: we reviewed the medical records of 260 patients who fulfilled the inclusion criteria for active surveillance. We performed a head-to-head comparison between the histological findings of specimens after radical prostatectomy (RP) and prostate biopsies. The PSIM score was calculated on the basis of positivity according to cutoffs (neutrophil-to-lymphocyte ratio (NLR) 2.0, platelets-to-lymphocyte ratio (PLR) 118 and monocyte-to-lymphocyte-ratio (MLR) 5.0), with 1 point assigned for each value exceeding the specified threshold and then summed, yielding a final score ranging from 0 to 3. Results: median NLR was 2.07, median PLR was 114.83, median MLR was 3.69. Conclusion: we found a significantly increase in the rate of pathological International Society of Urological Pathology (ISUP) ≥ 2 with the increase of PSIM. At the multivariate logistic regression analysis adjusted for age, prostate specific antigen (PSA), PSA density, prostate volume and PSIM, the latter was found the sole independent prognostic variable influencing probability of adverse pathology.

31 Background: Inflammatory markers such as the C-reactive protein (CRP), neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have recently been proposed as prognostic markers for post-operative complications and poor prognosis in solid tumors especially in colon cancer. However, there are few related reports in gastric cancer patients. Therefore, the aim of this study is to assess how perioperative inflammatory markers influence the prolonged postoperative ileus (PPOI) following gastric cancer surgery. Methods: Between 2013 and 2016, 435 patients were diagnosed with gastric cancer and underwent surgery in Gangnam Severance hospital. Patients were divided into prolonged postoperative ileus (PPOI) and control groups. Uncomplicated postoperative ileus (POI) is generally identified as an inevitable process after surgery, which typically resolves within 3 days. Ileus that persists for more than 3 days following surgery is termed PPOI. Results: The total PPOI rate was 33.8%. In univariate analysis, PPOI group was significantly associated with male sex, old age, open operative technique, preoperative gastric outlet obstruction and combined colon resection. PPOI group also was significantly associated with elevated perioperative inflammatory marker (pre- and post-operative CRP, NLR, and PLR). In multivariate analysis, open operative technique and elevated perioperative inflammatory markers (CRP, NLR and PLR) were identified as significant predictors of PPOI. In addition, postoperative length of hospital stay delayed in PPOI group compared with the control group (11.58 ± 9.48 vs.7.98 ± 5.44, respectively; P < 0.001). Conclusions: In this study, PPOI group was significantly associated with elevated perioperative inflammatory marker. Patients with PPOI also are more likely to have an increased postoperative hospital stay. Therefore, the perioperative inflammatory markers may be used as clinically relevant predictive markers for PPOI following gastric cancer surgery

Abstract Background The prognostic significance of inflammatory markers in solid cancers is well-established, albeit with considerable heterogeneity. This study sought to investigate the postoperative inflammatory marker trend in peritoneal carcinomatosis (PC), with a focus on colorectal PC (CPC), and to propose optimal surveillance periods and cutoffs. Methods Data were collected from a prospectively maintained database of PC patients treated at the authors’ institution from April 2001 to March 2019. The platelet–lymphocyte ratio (PLR), the neutrophil–lymphocyte ratio (NLR), and the lymphocyte–monocyte ratio (LMR) were collected preoperatively and on postoperative days 0, 1 to 3, 4 to 7, 8 to 21, 22 to 56, and 57 to 90 as averages. Optimal surveillance periods and cutoffs for each marker were determined by maximally selected rank statistics. The Kaplan–Meier method and Cox proportional hazard regression models were used to investigate the association of inflammatory markers with 1-year overall survival (OS) and recurrence-free survival (RFS) using clinicopathologic parameters. Results The postoperative inflammatory marker trend and levels did not differ between the patients with and those without hyperthermic intraperitoneal chemotherapy (HIPEC). Low postoperative LMR (days 4–7), high postoperative NLR (days 8–21), and high postoperative PLR (days 22–56) were optimal for prognosticating poor 1-year OS, whereas high postoperative PLR and NLR (days 57–90) and low postoperative LMR (days 8–21) were associated with poor 1-year RFS. A composite score of these three markers was prognostic for OS in CPC. Conclusions The reported cutoffs should be validated in a larger population of CPC patients. Future studies should account for the inflammatory response profile when selecting appropriate surveillance periods.

AbstractPrevious studies have reported conflicting results on the predictive role of the platelet-to-lymphocyte ratio (PLR) in detecting clinically significant prostate cancer (CSPCa) at the time of prostate biopsies. We explored the predictive value of pre-biopsy PLRs for CSPCa using our large-cohort database. Consecutive men with serum prostate-specific antigen (PSA) levels of ≥ 3.0 ng/mL or abnormal digital rectal examination (DRE) findings and who underwent prostate biopsies were included in the study. There was no significant difference in the pre-biopsy PLR between men with benign disease, clinically insignificant prostate cancer (CISPCa), and CSPCa. Only the subset of CSPCa patients with serum PSA levels of < 10 ng/mL showed lower PLRs than those with benign disease or CISPCa. In the entire patient cohort, multivariate analyses revealed that older age, diabetes mellitus, DRE abnormalities, higher serum PSA levels, and smaller prostate volume were predictors of CSPCa. However, the pre-biopsy PLR was not a significant predictor of CSPCa at the prostate biopsy in the entire patient cohort or the subset of patients with serum PSA levels of < 10 ng/mL. In summary, the pre-biopsy PLR is not an independent predictor of CSPCa at the prostate biopsy, regardless of the serum PSA level.

Background: Recognition and early detection of delirium in the intensive care unit (ICU) is essential to improve ICU outcomes. To date, neutrophil-lymphocyte ratio (NLR), one of inflammatory markers, has been proposed as a potential biomarker for brain disorders related to neuroinflammation. This study aimed to investigate whether NLR could be utilized in early detection of delirium in the ICU.Methods: Of 10,144 patients who admitted to the ICU, 1,112 delirium patients (DE) were included in the current study. To compare among inflammatory markers, NLR, C-reactive protein (CRP), and white blood cell (WBC) counts were obtained: the mean NLR, CRP levels, and WBC counts between the initial day of ICU admission and the day of initial delirium onset within DE were examined. The inflammatory marker of 1,272 non-delirium patients (ND) were also comparatively measured as a supplement. Further comparisons included a subgroup analysis based on delirium subtypes (non-hypoactive vs. hypoactive) or admission types (elective vs. emergent).Results: The NLR and CRP levels in DE increased on the day of delirium onset compared to the initial admission day. ND also showed increased CRP levels on the sixth day (the closest day to average delirium onset day among DE) of ICU admission compared to baseline, while NLR in ND did not show significant difference over time. In further analyses, the CRP level of the non-hypoactive group was more increased than that of the hypoactive group during the delirium onset. NLR, however, was more significantly increased in patients with elective admission than in those with emergent admission.Conclusion: Elevation of NLR was more closely linked to the onset of delirium compared to other inflammatory markers, indicating that NLR may play a role in early detection of delirium.

Abstract Background: Many patients undergo unwanted prostate biopsy due to unreliability of prostate-specific antigen (PSA). PSA density (PSAD), free PSA, free-to-total PSA ratio, prebiopsy MRI are used to diagnose prostate cancer (PCa). Since 1863, correlations between inflammation and cancer have been identified and explored; thus, the role of various blood parameters in detecting cancer has been studied, especially neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). Here, we evaluated whether these parameters before prostate biopsy can diagnose prostate cancer in our hospital.Methods: We conducted a retrospective study from January 2014 to January 2018. Prostate cancer patients were divided into significant cancer (Gleason Score ≥ 7) and insignificant cancer (Gleason Score < 7). NLR, PLR, and other clinical parameters were taken before the prostate biopsy. We then analyzed the associations of NLR and PLR alone or with PSA, with significant prostate cancer. Results: We included 463 patients, of whom 60.3% (279) had prostate cancer and 75.6 % (211) had a Gleason score (GS) of ≥ 7. PSA and PSAD in the clinically significant prostate cancer patient group were around two times more than those in the insignificant prostate cancer group. PV, NLR, PLR, and combined markers were more in the GS ≥ 7 population group. PSA combined with PLR (PPLR) and PSA with NLR (PNLR) had better area under a curve (AUC) (0.732 and 0.730, resp.), with statistical significance, than PSA, NLR, and PLR alone (0.723, 0.585, and 0.590). In the multivariate analysis using separate models with PSA and NLR or PLR compared to age, DRE-positive lesions, PV, PSAD; PNLR, and PPLR were statistically significant in finding aggressive prostate cancer. When combined markers were used together, despite the high correlations, PSA and NLR were nearly significant (p = 0.062) in detecting the GS ≥ 7 population.Conclusion: The combined use of PSA with PLR and PSA with NLR helps detect the differences between clinically significant and insignificant prostate cancer.

PurposeTo evaluate the diagnostic values of systemic immune-inflammation index (SII) and neutrophil–lymphocyte ratio (NLR) in patients with localized prostate cancer (PCa).MethodsBetween January 2014 and December 2019, 117 patients with benign prostate hyperplasia (BPH) and 278 patients with localized PCa who underwent radical prostatectomy (RP) were included in this study. The inflammatory markers including SII, NLR, platelet–lymphocyte ratio (PLR), lymphocyte–monocyte ratio (LMR), lymphocyte ratio (LR), neutrophil ratio (NR), mean platelet volume (MPV), and red cell distribution (RDW) of these two groups were examined and analyzed. ROC curve analysis was performed to assess the discriminative ability of inflammatory markers and their combination with tPSA for PCa. The binary logistic regression model was used to evaluate the association between significant inflammatory markers and risk of PCa.ResultsThe pathological results from RP specimen comprised 72 (25.90%) patients with pT1, 168 (60.43%) patients with pT2, and 38 (13.67%) patients with pT3. According to Student’s t test, patients with PCa had higher NLR (p = 0.034), SII (p = 0.008), and NR (p = 0.004), and lower LR (p = 0.025), MPV (p = 0.003), and TPV (p = 0.022) compared with patients with BPH; the distribution of age, PLR, LMR, RDW, f/t PSA ratio, and BMI did not show any significant differences. The AUC for NLR, SII, NR, and tPSA was 0.697 (p = 0.015), 0.719 (p &lt; 0.001), 0.647 (p = 0.009), and 0.708 (p &lt; 0.001), with threshold values of 1.6, 471.86, 65.15%, and 12.89 ng/ml, respectively. Patients were divided into two groups according to the threshold values, respectively. By using the multivariable logistic regression models, NLR ≥ 1.6 (OR, 2.731; 95% CI, 0.937–7.961, p = 0.042), SII ≥ 471.86 (OR, 1.274; 95% CI 0.473–3.433; p = 0.033), and PSA ≥ 12.89 ng/ml (OR, 1.443; 95% CI, 0.628–3.944; p = 0.014) were independent risk factors associated with PCa. The AUC for combination of NLR, SII, and NR with tPSA was 0.705 (p &lt; 0.001), 0.725 (p &lt; 0.001), and 0.704 (p &lt; 0.001), respectively.ConclusionThis study demonstrated that SII, NLR, and NR were all independent risk factors of PCa. These factors alone could provide better screen methods for PCa before biopsy. In addition, SII is a more powerful tool among these three inflammatory markers associated with PCa. Besides, combination of SII and NLR with tPSA had not much advantage compared with themselves alone.
