Purpose Association of the neutrophil-to-lymphocyte ratio (NLR) with mortality has not been comprehensively explored in critical limb ischemia (CLI) patients. We investigated the association between the NLR and clinical outcomes in CLI. Materials and methods We retrospectively enrolled consecutive CLI patients between 1/1/2013 and 12/31/2018. Receiver operating characteristic curve analysis determined NLR cutoffs for 1-year in-hospital, all-cause and cardiac-related mortality; major adverse cardiovascular events (MACEs); and major adverse limb events (MALEs). Results Among 195 patients (age, 74.0 years, SD: 11.5; 51.8% male; body mass index, 23.4 kg/m2, SD: 4.2), 14.4% exhibited acute limb ischemia. After 1 year, patients with NLR>8 had higher in-hospital mortality (21.1% vs. 3.6%, P<0.001), all-cause mortality (54.4% vs. 13.8%, P<0.001), cardiac-related mortality (28.1% vs. 6.5%, P<0.001), MACE (29.8% vs. 13.0%, P = 0.008), and MALE (28.1% vs. 13.0%, P = 0.021) rates than those with NLR<8. In multivariate logistic regression, NLR≥8 was significantly associated with all-cause (P<0.001) and cardiac-related (adjusted HR: 5.286, 95% CI: 2.075–13.47, P<0.001) mortality, and NLR≥6 was significantly associated with MALEs (adjusted HR: 2.804, 95% CI: 1.292–6.088, P = 0.009). Each increase in the NLR was associated with increases in all-cause (adjusted HR: 1.028, 95% CI: 1.008–1.049, P = 0.007) and cardiac-related (adjusted HR:1.027, 95% CI: 0.998–1.057, P = 0.073) mortality but not in-hospital mortality or MACEs. Conclusion CLI patients with high NLRs had significantly higher risks of 1-year all-cause and cardiac-related mortality and MALEs. The NLR can be used for prognostic prediction in these patients.

Introduction: Acute limb ischemia (ALI), classified according to Rutherford’s classification (RC), is a vascular emergency burdened by high rates of mortality and morbidity. The need of new and different prognostic values for ALI has emerged, and, among all, the neutrophil-to-lymphocyte ratio (NLR) has been proven as a strong outcome predictor in vascular disease. The aim of this study is to investigate the role of preoperative NLR in predicting clinical outcomes in patients presenting acute limb ischemia. Material and Methods: A single-center retrospective study was conducted between January 2015 and December 2019. Demographic and clinical characteristics, procedural technical aspects, postoperative and early (up to 30-day) outcomes were recorded. All enrolled patients were categorized into low- and high-NLR at baseline, using a cut-off value of 5. Study outcomes were 30-day all-cause mortality and amputation rates. Results: A total of 177 ALI patients were included in the final analysis (6 RC I, 44 RC IIA, 108 RC IIB, and 19 RC III), 115 males (65%), mean age 78.9 ± 10.4 years. Mean NLR at hospital presentation was 6.65 ± 6.75 (range 0.5–35.4), 108 (61.1%) patients presented a low-NLR, 69 (38.9%) a high-NLR. Immediate technical success was achieved in 90.1% of cases. At 30 days, freedom from amputation and freedom from death rates were 87.1% and 83.6%, respectively. At the univariate analysis, amputation (p < 0.0001, OR: 9.65, 95%CI: 3.7–25.19), mortality (p = 0.0001, OR: 9.88, 95%CI: 3.19–30.57), and cumulative event rates (p < 0.001, OR: 14.45, 95%CI: 6.1–34.21), were significantly different between the two groups according to NLR value. Multivariate analysis showed that a high baseline NLR value was an independent predictor of unfavorable outcomes in all enrolled patients. Consistently, at ROC analysis, a preoperative NLR > 5 was strongly associated with all outcome occurrences. Conclusion: Preoperative NLR value seems to be strongly related to ALI outcomes in this unselected population. The largest series should be evaluated to confirm present results.

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.
