e17050 Background: The role of Neutrophil to Lymphocyte Ratio (NLR) and Platelet to Lymphocyte Ratio (PLR) in prognostication of MIBC is not clearly understood. There is growing evidence that, as markers of inflammation, they may have prognostic utility in MIBC at radical cystectomy (RC). Methods: We performed a retrospective analysis of MIBC patients who underwent RC at the Cleveland Clinic from 2/2015 to 1/2018. 84 patients were identified who were either diagnosed with TaN0M0 treated with Neoadjuvant Chemotherapy (NAC) or T1-T4N0M0 disease treated with or without NAC. For NAC, 27 patients received gemcitabine and cisplatin, 2 patients received gemcitabine and carboplatin, 4 patients received unknown regimen, and 3 patients received MVAC. Of the patients, there were 1 with Ta, 34 with T1, 44 with T2, 1 with T3 and 4 with T4 disease. Complete Blood Count with Differential closest to or on the day of resection was used. NLR and PLR were calculated by dividing Absolute Neutrophil Count and Platelet Count by the Absolute Lymphocyte Count, respectively. PLR and NLR were dichotomized at the median. Outcomes were analyzed via Kruskal-Wallis test. Results: Median follow up of patients was 28.8 months. Median NLR and PLR were 15.7 and 263, respectively. Mean NLR and PLR were 18.9 and 310, respectively. NLR and PLR did not correlate with overall survival, recurrence free survival, T or N stage post resection, or pathological response. Females were found to have a higher NLR than males. Conclusions: Contrary to previous reports, our study did not find any prognostic value of NLR and PLR in MIBC patients at RC. Further evaluation of PLR and NLR in MIBC and correlation with molecular features may help understand its potential prognostic role in patients undergoing surgical resection.

Aim: To examine neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in prognosticating immunotherapy efficacy. Methods: A retrospective study of 156 patients with metastatic melanoma and non-small-cell lung cancer on PD-1 inhibitors. Results: Baseline NLR ≥5 was associated with worse progression-free survival (hazard ratio [HR]: 1.53; 95% CI: 1.01–2.31; p = 0.043) but nonsignificant worse overall survival trend (HR: 1.51; 95% CI: 0.98–2.34; p = 0.064). PLR ≥200 was associated with worse overall survival (HR: 1.94; 95% CI: 1.29–2.94; p = 0.002) and worse progression-free survival (HR: 1.894; 95% CI: 1.27–2.82; p = 0.002). NLR or PLR are prognosticating factors regardless of cancer types, with PLR having a stronger association with outcomes than NLR. Conclusion: High baseline NLR or PLR (alone and combined) were associated with worse immunotherapy efficacy regardless of cancer type, indicating their potential role as an agnostic marker for immunotherapy efficacy.

Abstract Context Due to the wide spectrum of clinical illness in coronavirus disease 2019 (COVID-19) patients, it is important to stratify patients into severe and nonsevere categories. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been evaluated rapidly by a few studies worldwide for its association with severe disease, but practically none have been conducted in the Indian population. This study was undertaken to examine the role of NLR and PLR in predicting severe disease in Indian patients. Objectives The objective was to study the association of NLR and PLR observed at the time of admission with maximum disease severity during hospitalization and to study their role in predicting disease severity. Material and Methods A total of 229 COVID-19 patients were admitted at the center during the study period. After applying inclusion and exclusion criteria, 191 patients were included in the study. The demographic, clinical, and laboratory (complete blood count, NLR, and PLR) data of all patients were obtained at the time of admission. Maximum disease severity of all patients was assessed during hospitalization. Statistical Analysis Chi-square and Mann–Whitney U tests were used to assess statistical significance. Receiver operating characteristic curve (ROC) was plotted for NLR and PLR to estimate the cutoff values and sensitivity and specificity using Youden’s index for predicting severe disease. Logistic regression analysis was used to estimate the odds ratios (OR) and 95% confidence intervals. Results Mean NLR and PLR were significantly higher in severe patients (NLR = 7.41; PLR = 204) compared with nonsevere patients (NLR = 3.30; PLR = 121). ROC analysis showed that NLR, in comparison to PLR, had a higher area under the curve (AUC) of 0.779, with a larger OR of 1.237 and cutoff of 4.1, and showed 69% sensitivity and 78% specificity in predicting severe disease. Cut off for PLR was 115.3, which showed 79% sensitivity and 62% specificity in predicting severe disease. Conclusion NLR and PLR, both showing acceptable AUCs, can be used as screening tools to predict disease severity. However, NLR was a better predictor of disease severity.

Introduction: Prognosis in patients with cancer is influenced by underlying tumour biology and also the host inflammatory response to the disease. There is limited evidence to suggest that an elevated neutrophil-lymphocyte ratio (NLR) predicts a poorer prognosis in patients undergoing nephrectomy for renal cell carcinoma (RCC). The aim of this paper is to investigate if patients undergoing nephrectomy for RCC with NLR ≤4 have a better overall and recurrence-free survival than patients with NLR >4.Methods: All patients who underwent nephrectomy at a single centre between January 1, 2011 and December 31, 2014 were identified. Patients were included if postoperative histology demonstrated RCC and if preoperative NLR was available. Patients were excluded if nephrectomy was not curative intent (i.e., cytoreductive nephrectomy), if primary tumour was graded to be T3b‒4 disease, if there was presence of nodal or metastatic disease on preoperative staging, or if adequate followup notes were not available. Primary and secondary outcomes were overall survival and recurrence-free survival, respectively.Results: A total of 154 patients were included in analysis of overall survival; 146 patients were included in analysis of recurrence-free survival. Patients with NLR ≤4 had a much better overall survival than patients with NLR >4 (95% vs. 78%; p=0.0219). Patients with NLR >4 also had higher rates of recurrence (p=0.0218).Conclusions: NLR may be a useful tool in identifying patients who may benefit from more frequent surveillance in the early postoperative period and may allow clinicians to offer surveillance schemes tailored to the individual patient.

e15505 Background: Inflammation seems to be significant factor in carcinogenesis and tumor progression of numerous cancers. Blood calculated neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein (CRP), lactate dehydrogenase (LDH), international normalized ratio (INR) can be evaluated as systemic inflammation markers and prognostic biomarker for many aims: survival outcomes, lymph node metastasis and recurrence, treatment responses in a variety of cancers. The purpose of this study was to investigate baseline associations between blood test parameters (NLR, PLR, LDH, CRP, INR) and their prognostic biomarker role for patient with metastatic gastric cancer, undergoing first-line chemotherapy Methods: Potential baseline inflammatory markers (platelets, neutrophils, lymphocytes, the platelet-lymphocyte ratio, the neutrophil-lymphocyte ratio, the serum C-reactive protein [CRP], the serum LDH, INR) were retrospectively analyzed in 32 patients with metastatic gastric cancer, IV stage (median of age – 60,50). Multivariate analyses were used to identify prognostic factors for overall survival (OS). Baseline values were compared with tumor characteristic and median survival times (MSTs). Results: Multivariate analysis identified due to Cox proportional-hazards regression showed significant longest OS in patients with: localization of primary tumor in antral part of gastric (HR 0,45, 95% CI 0,25-0,80, p = 0,0065); low baseline’s level of WBC (HR 1,17, 95% CI 1.02 - 1,35, p = 0,0219); low baseline’s level of neutrophil (HR 1,18, 95% CI 1.02 - 1,34, p = 0,0251). Level of LDH, CRP, INR didn’t show significant ratio for this cohort of patient. Peritoneum metastatic also didn’t significant affect on OS in patient with metastatic gastric cancer. Patients with low baseline’s platelet to lymphocyte ratio (HR 1,004, 95% CI 1,0009-1,0072, p = 0,0125) and low (from 0 to 3,0) neutrophil to lymphocyte ratio (HR 1,81, 95% CI 1,09-2,99, p = 0,0212) had a significantly longest OS time. Conclusions: Inflammatory markers can predict overall survival in stage IV gastric cancer. Simple and useful.

Abstract Background: The neutrophil-to-lymphocyte ratio is a significant prognostic marker in resectable colorectal cancer; however, there are no equivalent findings for perforated colon cancer. Using our colorectal cancer database, we retrospectively analyzed the data from 1995 to 2015 to determine whether the preoperative neutrophil-to-lymphocyte ratio is associated with survival outcomes in patients with perforated colon cancer.Methods: One-to-one propensity score matching was applied to minimize the difference between the high (>5) and low (≤5) neutrophil-to-lymphocyte ratio groups. Clinicopathological factors, long-term overall survival, and disease-free survival were analyzed and compared between the two groups. The primary outcomes were overall survival and disease-free survival.Results: Before propensity score matching, the high neutrophil-to-lymphocyte ratio group had a significantly higher prevalence of leukocytosis (low vs. high neutrophil-to-lymphocyte ratio groups: 12 [12.9%] vs. 46 [59.7%], p<0.001), lower serum albumin levels (low vs. high neutrophil-to-lymphocyte ratio groups: 30 [32.3%] vs. 42 [54.5%], p=0.003), and a higher emergent operation rate (low vs. high neutrophil-to-lymphocyte ratio groups: 5 [5.4%] vs. 20 [26.0%], p<0.001). After one-to-one propensity score matching, the groups comprised 41 patients each; none of the parameters were significantly different between the two groups. The mean follow-up period was 76.3 months. The 5-year overall survival (p=0.637) and disease-free survival (p=0.827) rates were not significantly different between the high and low neutrophil-to-lymphocyte ratio groups.Conclusions: The neutrophil-to-lymphocyte ratio has limited predictive value for determining outcomes in patients with perforated colon cancer.

Abstract Background We aimed to identify whether neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are more useful predictors after initial intention to treat than at the time of diagnosis. Methods We collected the medical data of 533 patients. The results of the peripheral blood sampling before the primary treatments were labeled as initial cohort, and those obtained between 24 and 36 months after initial treatment were defined as the 2nd cohort. Delayed metastasis has been defined as distant metastasis 2 years after treatment, and survival outcome was estimated and compared across groups. Results Median follow-up duration was 74 months (24–162 months), and 53 patients experienced delayed metastasis. In univariate analysis, metastasis-free survival, patient age at diagnosis, tumor size, axillary lymph node metastasis, HER-2 status, initial NLR and PLR, and 2nd NLR and PLR were found to be significantly associated with delayed metastasis. However, in multivariate analysis, only the 2nd NLR and PLR were found to be significantly associated with delayed metastasis, excluding initial NLR and PLR. Metastasis-free survival was analyzed through the pattern changes of NLR or PLR. The results revealed that patients with continued low NLR and PLR values at pre- and post-treatment (low initial values and 2nd values) showed a significantly better prognosis than those with a change in value or continued high NLR and PLR. Conclusions We identified that patients with persistent high NLR and PLR after initial treatment have significant worse prognosis in terms of late metastasis. Therefore, these results suggest that NLR and PLR are more useful in predicting prognosis post-treatment.

ObjectiveThe aim of this study was to conduct a meta-analysis to establish the prognostic value of platelet-to-lymphocyte ratio in cervical cancer.MethodsWe conducted a search in Medline and Embase datasets for articles published until May 1, 2018 to perform a meta-analysis to establish the prognostic value of platelet-to-lymphocyte ratio in cervical cancer. The primary survival outcomes were overall survival and progression-free survival. The pooled hazard ratios (HRs) and 95% confidence intervals (95% CIs) were combined to calculate overall effects. Cochran’s Q test and Higgins’ I2statistics were employed to estimate the heterogeneity. In addition, the subgroup analysis, sensitivity analysis, and meta-regression were performed to identify the source of heterogeneity. Egger’s linear regression test and Begg’s funnel plot and the trim and fill methods were employed to evaluate the publication bias.ResultsA total of 2616 patients from eight studies were enrolled in the meta-analysis. Significant association was observed between elevated platelet-to-lymphocyte ratio and a worse overall survival, with a combined HR of 1.49 (95% CI 1.24 to 1.79, I2=32.8%). Elevated platelet-to-lymphocyte ratio was significantly associated with a worse progression-free survival, with a combined HR of 1.65 (95% CI 1.17 to 2.33, I2= 49.4%). Subsequently, sensitivity analysis, subgroup analysis, and meta-regression model containing six predominant factors were applied to trace the origin of heterogeneity. However, no significant factors or studies were explored as the potential source of heterogeneity.ConclusionElevated pre-treatment platelet-to-lymphocyte ratio may be an adverse prognostic factor for overall survival and progression-free survival in patients with cervical cancer. Further investigations are warranted to determine the exact mechanism by which platelet-to-lymphocyte ratio impacts survival outcomes in cervical cancer.

Inflammatory markers have been studied in cancers and chronic states of inflammation. They are thought to correlate with tumor pathology through disruption of normal homeostasis. Markers such as neutrophil to lymphocyte ratio (NLR) among others have shown promise as prognostic tools in various cancers. In this study, we evaluate complete blood count based inflammatory markers in hepatocellular carcinoma (HCC) to predict overall and recurrence-free survival of patients after liver transplant. Between 2001 and 2017, all HCC indicated liver transplants were retrospectively reviewed. Inclusion criteria included presence of complete blood cell counts with differential within three months prior to transplantation. Exclusion criteria included retransplantation and inadequate posttransplant followup. A total of 160 patients with HCC were included in the study. Of those, 74.4% had hepatitis C virus as the underlying cause of HCC. Calculated Model for End stage Liver Disease (MELD) scores were statistically worse in patients with elevated NLR (≥5), derived NLR (≥3), and low lymphocyte to monocyte ratio (LMR) (<3.45), whereas elevated platelet to lymphocyte ratio (PLR) (≥150) did not correlate with MELD. Of the tumor characteristics, low LMR was associated with tumor presence and microvascular invasion on explant. Though overall survival trended towards better outcomes with low NLR and dNLR and high LMR, these did not reach statistical significance. High LMR also trended towards better recurrence-free survival without statistical significance. Low PLR was associated with statistically significant overall and recurrence-free survival. In conclusion, while prior studies in HCC have identified NLR as surrogate for tumor burden and survival, in this study we highlight that PLR is a good surrogate of mortality and recurrence-free survival in HCC transplant patients. Further, future study of PLR, NLR, and LMR in larger HCC populations before and after interventions may help clarify their clinical utility as a simple and noninvasive clinical tool as prognostic markers.
