Preoperative neutrophil-to-lymphocyte ratio plus platelet-to-lymphocyte ratioin predicting survival for patients with stage Ⅰ-Ⅱgastric cancerCSCD

Background:The preoperative neutrophil-to-lymphocyte ratio(NLR) and the platelet-to-lymphocyte ratio(PLR) are associated with poor prognosis of gastric cancer.We aimed to determine whether the combination of NLR and PLR(NLR-PLR) could better predict survival of patients after curative resection for stage Ⅰ-Ⅱ gastric cancer.Methods:We collected data from the medical records of patients with stage Ⅰ-Ⅱ gastric cancer undergoing curative resection between December 2000 and November 2012 at the Sun Yat-sen Cancer Center.The preoperative NLRPLR was calculated as follows:patients with both elevated NLR(≥2.1) and PLR(≥ 120) were given a score of 2,and patients with only one or neither were given a score of 1 or 0,respectively.Results:Kaplan-Meier analysis and log-rank tests revealed significant differences in overall survival(OS) among patients with NLR-PLR scores of 0,1 and 2(P < 0.001).Multivariate analysis showed that OS was independently associated with the NLR-PLR score[hazard ratio(HR) = 1.51,95%confidence interval(CI) 1.02-2.24,P = 0.039]and TNM stage(HR = 1.36,95%CI 1.01-1.83,P= 0.041).However,other systemic inflammation-based prognostic scores,including the modified Glasgow prognostic score,the prognostic nutritional index,and the combination of platelet count and NLR,were not.In TNM stage-stratified analysis,the prognostic significance of NLR-PLR was maintained in patients with stage Ⅰ(P < 0.001) and stage Ⅱ cancers(P= 0.022).In addition,the area under the receiver operating characteristic curve for the NLR-PLR score was higher than those of other systemic inflammation-based prognostic scores(P = 0.001).Conclusion:The preoperative NLR-PLR score is a useful predictor of postoperative survival in the patients with stage l-ll gastric cancer and may help identify high-risk patients for rational therapy and timely follow-up.

Diagnostic Power of Blood Parameters as Screening Markers in Gastric Cancer Patients

Background: Gastric cancer (GC) is the fifth most common cancer worldwide. Since development is usually asymptomatic, it is generally diagnosed at an advanced stage. The value of screening in patients with nonspecific symptoms for GC is controversial. Aim: The study aimed to evaluate whether hematological parameters (platelet count (PC), mean platelet volume (MPV), MPV/PC ratio, red blood cell distribution width (RDW), neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR)) are useful markers to differentiate between gastric cancer patients and healthy individuals. Materials and Methods: Sixty-one patients with gastric cancer and sixty-one healthy individuals were enrolled to the survey and a retrospective analysis of selected blood parameters was performed. Results: The mean values of PC, MPV, RDW, NLR, and PLR were significantly higher in GC patients compared to the control group. No statistical differences were observed in MPV/PC ratios. Likewise, no significant statistical differences were revealed in values of blood parameters among TNM stage groups. The RDW showed the highest diagnostic specificity and sensitivity. Conclusions: Hematological parameters: PC, MPV, RDW, NLR, PLR have diagnostic power and can discriminate patients with gastric cancer from patients without cancer. Blood parameters compared with clinical symptoms might alert physicians and patients and lead to performancce of upper gastrointestinal endoscopy, the gold standard in gastric cancer screening and thereby increase the early detection of cancer.

Could the Platelet-to-Lymphocyte Ratio be a Novel Marker for Predicting Invasiveness of Cervical Pathologies?

Purpose: To determine whether the preoperative platelet to lymphocyte ratio (PLR) could predict invasivenessof cervical pathologies. Materials and Methods: Patients with preinvasive and invasive diseases were reviewedretrospectively, over a nine-year period, 2005-2014. The pathological records and completed blood counts ofthe patients were collected and recorded in the SPSS program. Patients were divided in two groups, preinvasiveand invasive. Results: The median PLR was significantly higher in the invasive group than in the preinvasivegroup (p=0.03). There was a correlation between invasion of cervical cancer and white blood cell count, redcell distributing width (RDW), neutrophil-lymphocyte ratio (NLR), and PLR. Conclusions: This study showedthat patients with uterine cervical cancer may present with leukocytosis, increased RDW, NLR and PLR. Thesecheap and easily available parameters, especially PLR, may provide useful information about the invasivenessof cervical lesions.     

Prognostic Significance of Inflammation-associated Blood Cell Markers in Nonmetastatic Clear Cell Renal Cell Carcinoma

ObjectivesOur objective was to evaluate the effect of the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), lymphocyte/monocyte ratio (LMR), and red blood cell distribution width (RDW) on the survival outcomes of nonmetastatic clear cell renal cell carcinoma (ccRCC).Materials and MethodsWe accessed our single-center, urologic-oncologic registry to extract the data for patients who had undergone nephrectomy for nonmetastatic ccRCC. The optimal cutoff for these markers was determined using X-tile software, and survival analyses using Cox regression were performed.ResultsA total of 687 patients had undergone nephrectomy. The optimal cutoffs for NLR, PLR, LMR, and RDW were 3.3, 210, 2.4, and 14.3%, respectively. The NLR, PLR, LMR, and RDW were significantly associated with a larger pathologic tumor size, and stage, more aggressive Fuhrman grade, and the presence of tumor necrosis. After adjusting for age, baseline Eastern Cooperative Oncology Group, pathologic tumor and nodal stage, and Fuhrman grade, only PLR remained an independent prognostic marker for both cancer-specific survival (hazard ratio, 2.69; 95% confidence interval, 1.36-5.33; P = .004) and overall survival (hazard ratio, 2.19; 95% confidence interval, 1.36-3.50; P = .001). When the PLR was included with the Leibovich score and University of California, Los Angeles, integrated staging system, the Harrell’s c-index increased from 0.854 to 0.876 and 0.751 to 0.810, respectively, for cancer-specific survival at 5 years after nephrectomy. When risk stratified by the Leibovich risk group and UCLA integrated staging system, PLR was a significant prognostic factor only within the intermediate- to high-risk groups.ConclusionsPLR is a robust prognostic marker in nonmetastatic ccRCC that clearly outperforms other inflammatory indexes in those who had undergone nephrectomy. However, its prognostic effect was limited in the low-risk category of ccRCC.     

Elevated Serum Neutrophil to Lymphocyte and Platelet to Lymphocyte Ratios Could be Useful in Lung Cancer Diagnosis

Background: Lung cancer (LC) is still the primary cause of cancer deaths worldwide, and late diagnosis is amajor obstacle to improving lung cancer outcomes. Recently, elevated preoperative or pretreatment neutrophilto lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and mean platelet volume (MPV) detected inperipheral blood were identified as independent prognostic factors associated with poor survival with variouscancers, including colon cancer, esophageal cancer, gastric cancer and breast cancer. Objective: The aim ofthis study was to examine whether MPV, NLR and PLR could be useful inflammatory markers to differentiatelung cancer patients from healthy controls. An investigation was also made of the relationship between thesemarkers and other prognostic factors and histopathological subgroups. Materials and Methods: Retrospectivelyeighty-one lung cancer patients and 81 age-sexes matched healthy subjects included into the study. Patientswith hypertension, hematological and renal disease, heart failure, chronic infection, hepatic disorder and othercancer were excluded from the study. The preoperative or pretreatment blood count data was obtained fromthe recorded computerized database. Results: NLR and PLR values were significantly higher in the LC patientscompared to the healthy subjects.( NLR: 4.42 vs 2.45 p=0.001, PLR: 245.1 vs 148.2 p=0.002) MPV values weresimilar in both groups (7.7 vs 7.8). No statistically significant relationship was determined between these markers(MPV, NLR and PLR) and histopathological subgroups and TNM stages. Conclusions: NLR and PLR can beuseful biomarkers in LC patients before treatment. Larger prospective studies are required to confirm thesefindings.

目的:探讨术前外周静脉血中性粒细胞与淋巴细胞比值(NLR)在胸中下段食管鳞状细胞癌左胸入路根治术预后中的评估价值.方法:回顾性分析2007年1月至2011年12月首次治疗在我院经左胸入路行根治性切除的109例胸中下段食管鳞状细胞癌患者的临床病理资料,NLR临界值为2.5.结果:全组患者中位随访时间为38.0个月,术前NLR 0.89~6.16,中位值2.42,低NLR组(NLR<2.5)56例,高NLR组(NLR≥2.5)53例.术后病理淋巴结转移患者NLR高值的比例高于无淋巴结转移患者(P=0.028);不同病理TNM分期(I-III)间NLR高值的比例存在差异(P=0.006).高NLR组总体生存时间中位值为23.0个月,短于低NLR组61.0个月(P<0.001).单因素分析显示,病理T、N、TNM分期和NLR是患者预后不良的影响因素(P<0.001).Cox比例风险回归模型多因素分析显示,病理TNM分期(HR=2.377,P=0.015)和NLR(HR=2.887,P<0.001)是患者预后的独立影响因素.结论:术前外周静脉血NLR高是接受左胸入路根治性切除的胸中下段食管鳞状细胞癌患者总体生存预后不良的独立影响因素.
