The role of chronic inflammation,acting as an independent factor,on the onset of gastrointestinal carcinogenesis is now well accepted.However,even if there is an increase in the number of elements directly involving polymorphonuclear leukocytes (PMNL),as a major actor in digestive carcinogenesis,the different cellular and molecular events occurring in this process are still not completely understood.The transepithelial migration of PMNL,which is the ultimate step of the afflux of PMNL into the digestive mucosa,is a complex phenomenon involving sequential interaction of molecules expressed both on PMNL and on digestive epithelial cells.Chronic inflammatory areas rich in PMNL [so-called (chronic active inflammation)] and iterative transepithelial migration of PMNL certainly evoke intracellular signals,which lead toward progressive transformation of epithelia.Among these different signals,the mutagenic effect of reactive oxygen species and nitrates,the activation of the nuclear factor-κB pathway,and the modulation of expression of certain microRNA are key actors.Following the initiation of carcinogenesis,PMNL are involved in the progression and invasion of digestive carcinomas,with which they interact.It is noteworthy that different subpopulations of PMNL,which can have some opposite effects on tumor growth,in association with different levels of transforming growth factor-β and with the number of CD8 positive T lymphocytes,could be present during the development of digestive carcinoma.Other factors that involve PMNL,such as massive elastase release,and the production of angiogenic factors,can participate in the progression of neoplastic cells through tissues.PMNL may play a major role in the onset of metastases,since they allow the tumor cells to cross the endothelial barrier and to migrate into the blood stream.Finally,PMNL play a role,alone or in association with other cell parameters,in the initiation,promotion,progression and dissemination of digestive carcinomas.This review focuses on the main currently accepted cellular and molecular mechanisms that involve PMNL as key actors in digestive carcinogenesis. 展开更多

Objective:Cancer-associated inflammation and coagulation cascades play vital roles in cancer progression and survival.In this study,we investigated the significance of the combination of preoperative fibrinogen and the neutrophil-to-lymphocyte ratio(NLR)in predicting the survival of patients with non-small cell lung cancer(NSCLC).Methods:We retrospectively enrolled 589 patients with NSCLC who underwent surgery.The univariate and multivariate Cox survival analyses were used to evaluate the prognostic indicators,including the combination of fibrinogen and NLR(F-NLR).The cut-off values for fibrinogen,NLR,and clinical laboratory variables were defined by the receiver operating characteristic(ROC)curve analysis.According to the ROC curve,the recommended cut-off values for fibrinogen and the NLR were 3.48 g/L and 2.30,respectively.Patients with both a high NLR(≥2.30)and hyperfibrinogenemia(≥3.48 g/L)were given a score of 2,whereas those with one or neither were scored as 1 or 0,respectively.Results:Our results showed that F-NLR was an independent prognostic indicator for disease-free survival(DFS)[hazard ratio(HR),1.466;95%confidence interval(CI),1.243–1.730;P<0.001]and overall survival(OS)(HR,1.512;95%CI,1.283–1.783;P<0.001).The five-year OS rates were 66.1%,53.5%,and 33.3%for the F-NLR=0,F-NLR=1,and F-NLR=2,respectively(P<0.001).Correspondingly,their five-year DFS rates were 62.2%,50.3%,and 30.4%,respectively(P<0.001).In the subgroup analyses of the pathological stages,the F-NLR level was significantly correlated with DFS and OS in stage I and IIIA cancers.Conclusions:Preoperative F-NLR score can be used as a valuable prognostic marker for patients with resectable early-stage NSCLC. 展开更多

Objective This study aimed to explore the combined prognostic value of pretreatment neutrophil-tolymphocyte ratio(NLR), lymphocyte-to-monocyte ratio(LMR), and platelet-to-lymphocyte ratio(PLR) in newly diagnosed IE/IIE extranodal natural killer/T-cell lymphoma(ENKTL) treated with a P-Gemox regimen combined with radiotherapy or radiotherapy alone.Methods A total of 132 patients from 2009 to 2017 at the Sichuan Cancer Hospital were enrolled in the study. The cutoff values of NLR, LMR, and PLR using overall survival(OS) rate as an endpoint were obtained by the receiver operating curve. Results The cutoff value of NLR was 3.5. Patients with high NLR had significantly shorter progressionfree survival(PFS)(P < 0.001) and OS(P < 0.001) than those with low NLR. Similarly, the cutoff value of LMR was 3.0. The high LMR group had significantly longer PFS(P=0.001) and OS(P < 0.001) than the low LMR group. Similarly, the cutoff value of PLR was 191.7. The high PLR group was significantly associated with poor PFS(P < 0.001) and OS(P < 0.001) than the low PLR group. Furthermore, combining NLR, LMR, and PLR to build a new model to stratify patients into low-, intermediate-, intermediate-high-, and high-risk groups, there were also significant differences in PFS(P < 0.001) and OS(P < 0.001). The univariate analysis showed that presenting B symptoms, stage IIE, local tumor invasion, Eastern Cooperative Oncology Group score ≥ 2, elevated lactate dehydrogenase level, elevated NLR, decreased LMR, and elevated PLR were significantly associated with poor survival. The multivariate analysis demonstrated that PLR was an independent prognostic factor for both PFS(hazard ratio [HR]= 2.073, 95% confidence interval [CI]= 1.080–3.981, P = 0.028) and OS(HR = 2.127, 95% CI = 1.102–4.107, P = 0.025).Conclusion Elevated pretreatment PLR was a novel simple predictor of poor survival in patients with stage IE/IIE ENKTL. Combining NLR, LMR, and PLR could provide additional stratification. 展开更多

Renal cell carcinoma(RCC) is one of the ten most common malignancies.The prognosis of RCC is poor when the disease is in advanced stages,with five-year survival of less than 10%.However current assessment approaches are limited in their ability to prognosticate and guide therapeutic decision-making.Cellular-mediated inflammatory response is increasingly being recognised to have an important role in carcinogenesis of RCC.Various inflammatory markers have been found to identify patients with RCC at high risk of recurrence and predict survival.Neutrophil-lymphocyte ratio(NLR) is a simple and inexpensive inflammatory marker that has been shown to be of value in the assessment of patients with RCC.An elevated pretreatment NLR has been found to be associated with reduced overall survival,recurrence-free survival and progress-free survival and risk of recurrence in localized RCC.In addition,lower pretreatment NLR has been demonstrated to be associated with better clinical response to systemic therapy including vascular endothelial growth factor inhibitors,among patients with metastatic RCC.However,NLR has not been found to differentiate whether small renal masses of less than 40 mm are benign or malignant.Further research is needed to determine the cut-offs for NLR to predict different clinical outcomes and how post-treatment NLR can be used.In addition,more work is also needed to evaluate combining NLR with other biomarkers in a model to predict patients' clinical outcome or response to treatment for RCC. 展开更多

Therefore, we try to invest the peripheral inflammatory cell counts and neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) from our routine practice for the predictor of prognosis of breast cancer after resection. <strong>Patients and</strong> <strong>Methods: </strong>There were 574 breast cancer patients accepted surgical resection and registered in Cancer Registry Center of our hospital. Patient’s basic profiles, peripheral neutophil, lymphocyte and platelet count were measured for study. The scales of NLR and PLR were derived from the lower and higher normal range in cell count from neutrophil, lymphocyte and platelet respectively. Therefore, the scales for NLR and PLR were ≤1.62, 1.63 - 2.57, ≥2.58 and ≤224, 225 - 253, ≥254 respectively for analysis. <strong>Results: </strong>Poor 5-yr survival rate was found if higher cell counts of neutrophil and platelet (p ≤ 0.05). Three scales of NLR were ≤1.62, 1.63 - 2.57, ≥2.58, and their 5-year survival rates were 94%, 91% and 84% respectively (p = 0.019). In the subgroup of HER-2 (negative), and 3-Negative breast patients had a higher NLR of poor prognosis. But higher PLR was found less in 3-Negative and non in 3-Positive patients (p = 0.039). The PLR was ≤224, 225 - 253, ≥254 and their 5-year survival rates were 92%, 87%, and 64% respectively (p = 0.001);Multivariate Cox regression model for predictor of breast cancer patients who have 3.39 (PLR ≥ 254) and 2.45 (NLR ≥ 2.58 ) times risk (p = 0.02 and p = 0.002) of poor prognosis respectively. <strong>Conclusion: </strong>Peripheral inflammatory cell counts are easily to take in our clinical practice and have a potential role as predictors of prognosis. We have to pay attention to the trends of peripheral inflammatory cell count and their ratio in our clinical practice where possible. 展开更多
