Prognostic Role of Platelet-to-Lymphocyte and Neutrophil-to-Lymphocyte Ratios in Patients Irradiated for Glioblastoma Multiforme.

Previous studies suggested pre-operative platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) to be predictive factors in patients with glioblastoma multiforme (GBM). This study investigated the prognostic role of PLR and NLR prior to or at the beginning of radiotherapy. In 80 patients with GBM receiving conventionally fractionated radiotherapy plus concurrent temozolomide following resection or biopsy, 12 factors including PLR and NLR were retrospectively evaluated regarding progression-free survival (PFS) and overall survival (OS). On multivariable analyses, PLR ≤150, Karnofsky performance score (KPS) 90-100, and O6-methylguanine-DNA methyltransferase promoter methylation were significantly associated with improved PFS. Single lesion, KPS 90-100, and adjuvant chemotherapy were significantly associated with OS; PLR ≤150 showed a trend. NLR ≤3 showed a trend for associations with PFS and OS on univariable analyses. PLR prior to or at the beginning of radiotherapy was associated with treatment outcomes in patients irradiated for GBM and should be considered in future clinical trials.

The prognostic value of combined preoperative PLR and CA19-9 in patients with resectable gallbladder cancer.

The platelet to lymphocyte ratio (PLR) is the marker of host inflammation and it is a potential significant prognostic indicator in various different tumors. The serum carbohydrate antigen 19-9 (CA19-9) is a tumor-associated antigen and it is associated with poor prognosis of gallbladder cancer (GBC). We aimed to analyze the prognostic value of the combination of preoperative PLR and CA19-9 in patients with GBC. A total of 287 GBC patients who underwent curative surgery in our institution was included. To analyze the relationship between PLR and CA19-9 and clinicopathological features. A receiver operating characteristic (ROC) curve was used to identify the optimal cutoff value for PLR and CA19-9. The Kaplan-Meier method was used to estimate the overall survival (OS). Meanwhile, the univariate and multivariate Cox regression models were used to assess the risk factors for OS. The cutoff values of 146.82 and 36.32U/ml defined as high PLR and high CA19-9, respectively. Furthermore, survival analysis showed that patients with PLR > 146.82 and CA19-9 > 36.32 U/ml had a worse prognosis than patients with PLR ≤ 146.82 and CA19-9 ≤ 36.32 U/ml, respectively. The multivariate analysis demonstrated that PLR (hazard ratio (HR) = 1.863, 95% CI: 1.366-2.542, P < 0.001) and CA19-9 (HR = 1.412, 95% CI: 1.021-1.952, P = 0.037) were independent prognostic factors in the GBC patients. When we combined these two parameters, the area under the ROC curve increased from 0.624 (PLR) and 0.661 (CA19-9) to 0.711. In addition, the 1-, 3-, and 5-year OS of group A (patients with PLR ≤ 146.82 and CA19-9 ≤ 36.32 U/ml), group B (patients with either of PLR > 146.82 or CA19-9 > 36.32 U/ml) and group C (patients with PLR > 146.82 and CA19-9 > 36.32 U/ml) were 83.6%, 58.6%, 22.5%, 52.4%, 19.5%, 11.5%, and 42.3%, 11.9%, 0%, respectively. The preoperative PLR and serum CA19-9 are associated with prognosis of patients with GBC. The combination of PLR and CA19-9 may serve as a significant prognostic biomarker for GBC patients superior to either PLR or CA19-9 alone.

The correlation between preoperative neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio and postoperative recurrence of chronic rhinosinusitis

Objective:Neutrophil-to-lymphocyte ratio （NLR） and platelet-to-lymphocyte ratio （PLR） play important roles in the poor prognosis of different inflammatory and neoplastic diseases, but their effects on postoperative recurrence of chronic rhinosinusitis（CRS） are unknown. The aim of this study was to investigate the correlation between preoperative NLR and PLR and the risk of postoperative recurrence in CRS. Methods:Clinical data were collected from patients with CRS who underwent initial functional endoscopic sinus surgery from October 2018 to February 2022 at our institution. Follow-up was until February 2023, and the study endpoint was defined as patient postoperative recurrence or follow-up time up to date. The optimal preoperative NLR and PLR threshold values were obtained based on subject work curve analysis, and they were divided into high and low level subgroups, respectively, and the clinical characteristics and postoperative recurrence rates of patients were compared between groups; patients were divided into non-recurrent CRS and recurrent CRS according to their postoperative recurrence, and Kaplan-Meier survival curves and logistic regression analysis were performed to explore the correlation between NLR and PLR and CRS The correlation between NLR and PLR and postoperative recurrence was investigated by Kaplan-Meier survival curve and logistic regression analysis. Results:A total of 630 patients with CRS were included, including 382 and 140 patients with high NLR and high PLR, respectively. The postoperative recurrence rates of CRS patients in the high NLR and high PLR groups were significantly higher than those in the low NLR and low PLR groups（P<0.05）. The recurrent CRS had higher NLR and PLR levels and higher proportion of high NLR and high PLR than the non-recurrent CRS（P<0.05）, and similarly the duration of recurrent CRS and the rate of allergic rhinitis with recurrence were significantly higher than the non-recurrent CRS（P<0.05）. Kaplan-Meier survival curves showed that postoperative CRS was significantly higher in the high NLR and high PLR groups compared with the low NLR and low PLR groups. recurrence was significantly higher（P<0.05）. In addition, logistic regression analysis showed that high NLR, high PLR, disease duration, and combined allergic rhinitis were significantly associated with an increased risk of postoperative recurrence of CRS（P<0.05）. Conclusion:Both high preoperative NLR and high PLR are independent risk factors for postoperative recurrence of CRS, and they are expected to be new indicators for postoperative prognostic assessment and risk stratification of CRS patients. In addition, disease duration and comorbid allergic rhinitis were significantly associated with the risk of postoperative recurrence of CRS.

The value of preoperative neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and red blood cell distribution width in predicting positive surgical margin after laparoscopic radical prostatectomy.

Prostate cancer (PCa) is one of the most common malignant tumors in men, and laparoscopic radical prostatectomy (LRP) is commonly used to treat localized and advanced PCa. Positive surgical margin (PSM) is one of the most frequent problems faced by surgeons. This study aimed to explore the value of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and red blood cell distribution width (RDW) in predicting PSM after LRP. Three hundred and twenty patients with PCa were admitted and underwent LRP in Beijing Chaoyang Hospital from January 2017 to June 2023. Patients were randomly divided into a training set (225 cases) and a validation set (95 cases) in a 7:3 ratio. NLR, PLR, and RDW were significantly higher in the PSM group than in the negative surgical margins (NSM) group. In addition, the NLR, PLR, and RDW values correlated with clinical T stage, Gleason score, and seminal vesicle invasion in the PSM group. In training set, ROC curve analysis revealed that the optimal cutoff values of NLR, PLR, and RDW for predicting postoperative PSM in PCa were 2.31, 115.40, and 12.85%, respectively. Multivariate Logistic regression analysis showed NLR and RDW were the clinical independent predictors. The area under the curve (AUC, 0.770, 95% CI 0.709-0.831) for postoperative PSM was the highest when a combination of the three parameters was used, with sensitivity and specificity of 62.5% and 85.2%, respectively. In validation set, the AUC values for NLR, PLR, RDW and the three markers combined were 0.708, 0.675, 0.723, and 0.780, respectively. Correlation analysis showed that in the PSM group, NLR was positively correlated with PLR and RDW, and PLR was positively correlated with RDW. By contrast, in the NSM group, a positive association was only found between NLR and PLR. Higher preoperative NLR, PLR, and RDW values were associated with postoperative PSM. Additionally, the three markers combined may be useful to predict PSM.

Correlation between preoperative peripheral blood NLR, PLR, LMR and prognosis of patients with head and neck squamous cell carcinoma

BackgroundMarkers that can be used to evaluate the prognosis of patients with head and neck squamous cell carcinoma (HNSCC) remain undefined.ObjectiveThis study aimed to investigate the prognostic impact of preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) in patients with HNSCC who underwent surgery-based treatment for the first time.MethodsThis retrospective study included patients HNSCC who underwent surgery-based treatment at our institution between January 2018 and December 2020. Specificity and sensitivity were analyzed using receiver operating characteristic (ROC) curves and the critical value was determined. Patients were divided into low and high groups according to NLR, PLR, and LMR the critical value. Log-rank and Cox proportional hazards models were used to evaluate the associations between preoperative NLR, PLR, LMR, and overall survival (OS).ResultsA total of 304 patients with HNSCC were included, of whom 190 (62.5%) and 114 (37.5%), 203 (66.8%) and 101 (33.2%), 98 (32.2%), and 206 (67.8%) cases were classified as low NLR and high NLR groups, low PLR and high PLR groups, and low LMR and high LMR groups, respectively. Univariate analysis showed that white blood cell count (WBC), neutrophil count (NEU), platelet count (PLT), NLR, pathologic N stage (pN stage), TNM stage and postoperative complications were significantly associated with OS (p < 0.05). Multivariate analysis showed that NEU, NLR, TNM stage and postoperative complications were independent negative prognostic factors for HNSCC (p < 0.05).ConclusionPreoperative NLR is an independent negative prognostic factor for HNSCC. Patients with an increased NLR may have a poor OS.

Relationship Between Platelet-to-Lymphocyte Count Ratio and Acute Kidney Injury Following Surgery of Stanford Type A Aorta Dissection

ObjectiveThe aim of this study was to evaluate the correlation between the hematological index of platelet to lymphocyte ratio (PLR) and the occurrence of acute kidney injury (AKI) following surgery of Stanford acute type A aorta dissection (ATAAD).MethodsWe analyzed the perioperative data of patients with ATAAD who were treated surgically in Fujian Provincial Hospital from December 2016 to December 2021.ResultsPatients were divided into AKI (n = 66) and non-AKI (n = 36) groups based on the Kidney Disease: Improving Global Outcomes (KDIGO). There was no difference in preoperative PLR values (T0 PLR). In addition, the PLR within 24 h (T1 PLR) following surgery was higher in the AKI group than in the non-AKI group (P = 0.001). Reintubation rates, intensive care unit (ICU) stay, and 30-day mortality were significantly different in the AKI group (P = 0.004, P = 0.002 and P = 0.002). Multivariate analyses showed that higher body mass index (BMI) and reduced T1 PLR were the risk factors for postoperative AKI. Receiver operating characteristic (ROC) curve analysis revealed that the decline in the cut-off level of T1 PLR predicted AKI:144.6, the area under the curve (AUC):[95%CI] 0.7146, 0.6112–0.8181, and P = 0.0004, with a sensitivity of 58.33% and a specificity of 77.27%.ConclusionsThis retrospective study demonstrated that a decreased T1 PLR after surgery is a risk factor for the occurrence of postoperative AKI in ATAAD patients and has possible predictive value for AKI.

Prediction of postoperative hypokalemia in patients with oral cancer undergoing en bloc cancer resection: a retrospective cohort study

BackgroundThe factors associated with postoperative hypokalemia in patients with oral cancer remain unclear. We determined the preoperative factors associated with postoperative hypokalemia in patients with oral cancer following en bloc cancer resection and established a nomogram for postoperative hypokalemia prediction.MethodsData from 381 patients with oral cancer who underwent en bloc cancer resection were retrospectively analyzed. Univariate and multivariate analyses were performed to identify the risk factors for postoperative hypokalemia. We used receiver operating characteristic (ROC) curves to quantify the factors’ effectiveness. A nomogram was created to show each predictor’s relative weight and the likelihood of postoperative hypokalemia development. The multinomial regression model’s effectiveness was also evaluated.ResultsPreoperative factors, including sex, preoperative serum potassium level, and preoperative platelet-to-lymphocyte ratio (PLR), were significantly associated with postoperative hypokalemia. Based on the ROC curve, the preoperative serum potassium and PLR cut-off levels were 3.98 mmol/L and 117, respectively. Further multivariate analysis indicated that female sex, preoperative serum potassium level < 3.98 mmol/L, and preoperative PLR ≥ 117 were independently associated with postoperative hypokalemia. We constructed a predictive nomogram with all these factors for the risk of postoperative hypokalemia with good discrimination and internal validation.ConclusionsThe predictive nomogram for postoperative hypokalemia risk constructed with these factors had good discrimination and internal validation. The developed nomogram will add value to these independent risk factors that can be identified at admission in order to predict postoperative hypokalemia.

The Relation Between Serum-based Systemic Inflammatory Biomarkers and Locoregional Lymph Node Metastasis in Clinical Stages I to II Right-sided Colon Cancers: The Role of Platelet-to-Lymphocyte Ratio.

It aimed to evaluate the relationship between the systemic inflammatory markers and the lymph node metastasis in clinical stages I to II right-sided colon cancers. A total of 51 eligible clinical stages I to II right-side located colon cancer patients were included in the study. Complete mesocolic excision and central vascular ligation procedures were performed in all cases. All the patients were divided into 2 main groups, pN - (n = 22) and pN + (n = 29). Demographic parameters, preoperative serum-based inflammatory biomarkers, and histopathological findings were compared between the groups. The mean age was 61.0 (54 to 71) years. Of the patients, 51.0% (26/51) were females. The open surgical approach was performed on 54.9% (28/51) of the patients and 45.1% (23/51) was performed laparoscopy. The mean total number of retrieved lymph nodes was 29.1. The lympho-vascular invasion was significantly higher in the pN + group (89.7% vs 50.0%). There were no significant differences in neutrophil-to-lymphocyte ratio, C-reactive protein-to-albumin ratio, mean platelet volume-to-platelet ratio, hemoglobine-albuminelymphocyte-platelet score, systemic inflammation index, lymphocyte-to-monocyte ratio, neutrophil-to-monocyte ratio, lymphocyte-to-C-reactive protein ratio (LCR), neutrophil-to-albumin ratio, and prognostic nutritional index. However, the mean platelet-to-lymphocyte ratio (PLR) was significantly lower in the pN + group (pN - : 282.1 vs pN + : 218.7, P = 0.048). The cutoff value for PLR was determined as 220 according to receiver operating characteristic analysis, with a 63.6% sensitivity and 65.6% specificity. Although it has limited sensitivity and specificity, decreased preoperative PLR was significantly associated with lymph node metastasis in patients with clinical stages I to II right-sided colon cancer. It should be considered as a biomarker for nodal involvement when planning treatment strategies.

Significance of the Neutrophil-to-Lymphocyte Ratio, Platelet-to-Lymphocyte Ratio, and Preoperative Nutritional Index as Predictors of Morbidity in Patients Who Underwent Liver Resection for Alveolar Echinococcosis.

We aimed to evaluate the significance of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and preoperative nutritional index (PNI) as predictors of morbidity in patients who underwent liver resection for alveolar echinococcosis. This single-center study was designed as a retrospective study after obtaining ethical committee approval. The files of patients hospitalized at Ataturk University Faculty of Medicine, Erzurum, Turkey, between 2010 and 2019 and who underwent resection or liver transplantation for liver alveolar cysts were reviewed. Demographic features, laboratory parameters (complete blood count and biochemical parameters), lesion localizations and characteristics, type of surgery, intraoperative and postoperative complications (morbidity), and mortality status were evaluated by scanning patients' files. Preoperative blood samples were taken the day before the surgery, which is the period farthest from surgical stress, to have more accurate results. By contrast, postoperative blood samples were taken on the first postoperative daywhen surgical stress was the highest. The differences between the morbidity groups, including NLR, PLR, and PNI, were compared. Of the 172 patients in the study, 96 (55.8%) were female. The mean age of all patients was 48.51±15.57 (18-90). Perioperative complications were seen in 30 (17.4%) patients, while the morbidity and mortality rates of the study were 28.5% and 19.2%, respectively. Age, gender of patients, and preoperative laboratory parameters, including NLR, PLR, and PNI, did not affect morbidity. However, the presence of perioperative vascular injury (P=0.040) and complications (P=0.047), low postoperative lymphocyte rates (P=0.038), and high postoperative NLR were associated with increased morbidity. In addition, the mortality rate was significantly increased in patients with morbidity (P<0.001). From the results of the present study, it was found that preoperative parameters did not affect morbidity, while increased postoperative NLR levels and decreased lymphocyte rates increased morbidity.

39. HIGH PREOPERATIVE PLATELET TO LYMPHOCYTE RATIO IS ASSOCIATED WITH A GREATER RISK OF POSTOPERATIVE COMPLICATIONS AND RECURRENCES IN ESOPHAGEAL CANCER

Abstract Background Neoadjuvant treatment is currently the gold standard for advanced esophageal squamous cell carcinoma (ESCC). Several studies have examined the value of blood count-based indexes for predicting short- and long-term outcomes after esophagectomy for ESCC, but the relative predictive value of pretreatment, preoperative, and postoperative indexes has not yet been examined. Methods This study included 320 patients with thoracic ESCC who underwent subtotal esophagectomy after neoadjuvant chemotherapy or chemoradiotherapy at our institution. A total of 19 candidate blood parameters were measured before neoadjuvant treatment as well as preoperatively and postoperatively. The ability of the parameters to predict postoperative complications, overall survival (OS), and relapse-free survival (RFS) were assessed using receiver operating characteristic (ROC) curve analysis and Cox regression analysis. Results ROC curve analysis indicated that preoperative platelet to lymphocyte ratio (PLR) had the best predictive value with an optimal cutoff value of 166. Patients with high preoperative PLR (≥166) had significantly shorter OS and RFS and significantly higher incidences of hematogenous recurrence and postoperative pneumonia compared with patients with low preoperative PLR (&amp;lt;166). In multivariate analysis, high preoperative PLR and high preoperative serum carcinoembryonic antigen level were independent predictors of poor prognosis. Conclusion Preoperative PLR is a good predictor of short- and long-term prognosis in patients with advanced ESCC who receive neoadjuvant treatment followed by radical resection.

The predictive role of hematologic markers in resectable NSCLC patients treated with neoadjuvant chemoimmunotherapy: a retrospective cohort study.

Neoadjuvant chemoimmunotherapy is an important therapeutic modality for resectable nonsmall cell lung cancer (NSCLC). The roles of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio in predicting the efficacy and prognosis of patients with resectable NSCLC receiving neoadjuvant chemoimmunotherapy remain uncertain. This study aimed to explore the association of baseline and preoperative NLR, platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio with the treatment response and survival of patients with resectable NSCLC treated with neoadjuvant chemoimmunotherapy. Data of patients with resectable NSCLC treated with neoadjuvant chemoimmunotherapy between May 2019 and July 2022 at our institute, were retrospectively analyzed. Peripheral blood cell counts were obtained at baseline and before surgery. Data that may affect treatment efficacy were also collected and analyzed, including age, sex, BMI, cumulative smoking exposure, pathological type, clinical stage, PD-L1 tumor proportion score, immune checkpoint inhibitors, dosage of neoadjuvant therapy, duration from final therapy to surgery, and baseline and preoperative oncological markers. The present work has been reported in compliance with REporting recommendations for tumor MARKer prognostic studies (REMARK) criteria and guidelines (Supplemental Digital Content 1, http://links.lww.com/JS9/A860 ). A total of 116 patients were included in the study. Univariate logistic regression analysis showed that a higher baseline NLR ( P =0.001) and preoperative NLR ( P =0.001) were associated with a lower incidence of pathological complete response (pCR) following neoadjuvant therapy. Multivariate analysis indicated that a lower incidence of pCR was achieved in the high baseline NLR group ( P =0.014). Higher baseline NLR ( P =0.021), preoperative NLR ( P =0.004) and higher preoperative CEA levels ( P =0.059) were associated with shorter disease-free survival (DFS). Multivariate Cox proportional hazard regression analyses showed that shorter DFS was achieved in the high preoperative NLR group ( P =0.033). In patients with resectable NSCLC treated with neoadjuvant chemoimmunotherapy, a higher baseline NLR was associated with a lower incidence of pCR, and a higher preoperative NLR was associated with a shorter DFS. However, a future prospective study with a large sample size and long-term follow-up is needed to verify the predictive value of NLR in these patients.

Atrial Fibrillation and Perioperative Inflammation (FIBRILLAMMED Study): A Retrospective Analysis of the Predictive Role of Preoperative Albumin-Adjusted Platelet-Leukocytic Indices in OPCABG.

New-onset atrial fibrillation (NOAF), an important postoperative complication, has pertinent inflammatory links. Motivated by the encouraging literature on the prognostic role of hypoalbuminemia, leukocytic indices [LIs: neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR)], systemic inflammation response index (SIRI=NLR×monocyte) and platelet-leukocytic indices [PLIs: platelet-to-lymphocyte ratio (PLR)], systemic immune inflammation index (SII=NLR×platelet), aggregate index of systemic inflammation (AISI=NLR×platelet×monocyte), we sought to investigate the NOAF-predictive value of preoperative albumin-adjusted indices (aa-LIs and aa-PLIs) in an off-pump coronary artery bypass grafting (OPCABG) setting. Of 899 patients, 151 patients (16.79%) developed the primary outcome i.e. NOAF that was analyzed further retrospectively for its predictors instead of the highlighted text perioperative data of 899 patients undergoing elective OPCABG, were retrospectively analyzed. The study participants were categorized into non-NOAF and NOAF groups (defined as new-onset atrial arrhythmia with irregular RR interval with indistinct P wave in the first week postoperatively). One hundred and fifty-one patients (16.79%) developed NOAF. On univariate analysis: age, smoker status, The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, systemic hypertension, diabetes mellitus, prior congestive heart failure (CHF), and a higher preoperative NLR, PLR, SII, and albumin were significant predictors of NOAF. While age, CHF, and EuroSCORE II retained predictive significance in multivariate analysis, LI-PLIs and albumin did not emerge as independent NOAF predictors. Notably, aa-NLR, aa-PLR, and aa-SII independently predicted NOAF on the computation of model-estimates in the regression analysis (Odds ratio; 95% confidence interval: 31.05;15.75-70.61, 1.04;1.02-1.05, 1.12;1.10-1.14, respectively, P < 0.001). aa-NLR ≥1.32, aa-PLR ≥52.64, and aa-SII ≥344.38 predicted NOAF with the respective AUC;sensitivity;specificity of 0.66;63.6%;73.3%, 0.63;66.2%;59.0%, and 0.65;58.3%;78.2%. Preoperative aa-NLR, aa-PLR and aa-SII also positively correlated with CHA2DS2-VASc score (R=0.40, 0.45 and 0.42; P < 0.001). The independent NOAF predictive value of aa-NLR, aa-PLR, and aa-SII reiterates the inflammatory relationship of the arrhythmic complication following OPCABG.

The Role of Combined Inflammatory Biomarkers in the Diagnosis of High- and Low-Virulence FRI Among High-Risk Lower Extremity Fractures.

The aim of this study is to evaluate the diagnostic accuracy of infection-related biomarkers in high-risk lower limb injury patients with fracture-related infection (FRI) caused by high-/low-virulence microorganisms. This study was a retrospective analysis of patients with high-risk lower extremity fractures (including tibial plateau, calcaneus, and Pilon fractures) who underwent open reduction internal fixation (ORIF) surgery from January 2017 to February 2022. Peripheral blood samples were collected within 24 hours of admission, and the following information was evaluated: gender, age, BMI, smoking, comorbidities, injury information, surgical details, values for serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), as well as neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR). A total of 576 patients receiving lower extremity fracture surgery were included in this study. Fifty-one patients (8.85%) were identified as FRI, and 28 (54.9%) of these 51 cases were further classified as high-virulence group. The median levels of CRP, ESR, NLR, and MLR were significantly higher in the FRI group than in the non-FRI group (p < 0.01). Similarly, the marginally significantly higher levels of CRP and NLR presented in the high-virulence group, compared to the low-virulence group (p < 0.1). The AUC areas of CRP, NLR, and CRP+NLR were 0.826, 0.650, and 0.873, respectively. We calculated the optimal cut-off points for CRP+NLR as diagnostic markers of high-virulent infection was 0.377. This study showed the incidence of FRI in high-risk lower extremity fractures was 8.9%, and identified preoperative serum biomarkers, including CRP, ESR, NLR, and PLR, as useful tools for assisting in the diagnosis of infection. Additionally, the combination of CRP with NLR played a discriminating clinical role in postoperative infections caused by different virulence. Clinical study.

The postoperative platelet-to-lymphocyte ratio predicts the outcome of patients undergoing pancreaticoduodenectomy for pancreatic head cancer.

The preoperative platelet-to-lymphocyte ratio (PLR) has been reported as an important prognostic index for pancreatic ductal adenocarcinoma (PDAC); however, the significance of the postoperative (post-op) PLR for this disease has not been elucidated. We analyzed data on 118 patients who underwent pancreaticoduodenectomy for pancreatic head PDAC, collected from a prospectively maintained database. The post-op PLR was obtained by dividing the platelet count after surgery by the lymphocyte count on post-op day (POD) 14. The patients were divided into two groups according to a post-op PLR of < 310 or ≥ 310. Survival data were analyzed. A high post-op PLR was identified as a significant prognostic index on univariate analysis for disease-free survival (DFS) and overall survival (OS). The post-op PLR remained significant, along with tumor differentiation and adjuvant chemotherapy, on multivariate analysis for OS (hazard ratio = 2.077, 95% confidence interval: 1.220-3.537; p = 0.007). The post-op PLR was a significant independent prognostic index for poor DFS, along with tumor differentiation and lymphatic invasion, on multivariate analysis (hazard ratio = 1.678, 95% confidence interval: 1.056-2.667; p = 0.028). The post-op PLR in patients with pancreatic head PDAC was an independent predictor of DFS and OS after elective resection.

A new scoring system with simple preoperative parameters as predictors of early recurrence of pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) often recurs early after radical resection, and such early recurrence (ER) is associated with a poor prognosis. Predicting ER is useful for determining the optimal treatment. One hundred fifty-three patients who underwent pancreatectomy for PDAC were divided into an ER group (n = 54) and non-ER group (n = 99). Clinicopathological factors were compared between the groups, and the predictors of ER and prognosis after PDAC resection were examined. The ER group had a higher platelet count, higher platelet-to-lymphocyte ratio (PLR), higher preoperative CA19-9 concentration, higher SPan-1 concentration, larger tumor diameter, and more lymph node metastasis. The receiver operating characteristic (ROC) curve analysis identified cut-off values for PLR, carbohydrate antigen 19-9 (CA19-9), SPan-1, and tumor diameter. In the multivariate analysis, a high PLR, high CA19-9, and tumor diameter of >3.1 cm were independent predictors of ER after resection (all p < 0.05). When the parameter exceeded the cut-off level, 1 point was given, and the total score of the three factors was defined as the ER prediction score. Next, our new ER prediction model using PLR, CA19-9 and tumor diameter (Logit(p) = 1.6 + 1.2 × high PLR + 0.7 × high CA19-9 + 0.5 × tumor diameter > 3.1cm) distinguished ER with an area under the curve of 0.763, a sensitivity of 85.2%, and a specificity of 55.6%. ER after resection of PDAC can be predicted by calculation of a score using the preoperative serum CA19-9 concentration, PLR, and tumor diameter.

Predictive value of preoperative inflammatory indexes for postoperative early recurrence of hepatitis B-related hepatocellular carcinoma.

To investigate the predictive value of preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic inflammation response index (SIRI), and systemic immune inflammation index (SII) for early recurrence after liver resection in patients with hepatitis B-related hepatocellular carcinoma. A retrospective study was conducted on 162 patients who underwent hepatitis B-related hepatocellular carcinoma (HCC) resection between January 2013 and April 2016. The Youden index was utilized to calculate the optimal cut-off value. The Pearson Chi-square test was applied to analyze the relationship between inflammatory indexes and common clinical and pathological features. The Kaplan-Meier method and Log-Rank test were implemented to compare the recurrence-free survival rate within 2 years of the population. The Cox regression analysis was used to identify the risk factors for early postoperative recurrence. The best cut-off values of SIRI, PLR, NLR and SII were 0.785, 86.421, 2.231 and 353.64, respectively. Tumor diameter, degree of tumor differentiation, vascular invasion, SIRI>0.785, PLR>86.421, NLR>2.231 and SII>353.64 were risk factors for early recurrence. Combining the above seven risk factors to construct a joint index, the AUC of the joint prediction model was 0.804. The areas under the ROC curves of SIRI, PLR, NLR, and SII were 0.659, 0.725, 0.680, and 0.723, respectively. There was no significant difference in the predictive ability between the single inflammatory index models, but the predictive performance of the joint prediction model was significantly higher than that of the single inflammatory index models. The patients with lower SIRI, PLR, NLR, SII and joint index value had longer recurrence-free survival within 2 years. The joint index CIP, constructed by combining preoperative SIRI, PLR, NLP and SII with pathological features, can better predict the early recurrence of HBV-related HCC patients after surgery, which is beneficial in identifying high-risk patients and assisting clinicians to make better clinical choices.

Prognostic Significance of Preoperative NLR, MLR, and PLR Values in Predicting the Outcome of Primary Cytoreductive Surgery in Serous Epithelial Ovarian Cancer

(1) The degree of cytoreduction achieved during primary debulking surgery (PDS) is an important prognostic factor for the survival of patients with epithelial ovarian cancer (EOC). Our aim was to investigate the prognostic value of preoperative laboratory parameters for the outcome of PDS. (2) We analyzed the preoperative laboratory parameters of 150 serous EOC patients who underwent PDS between 2006 and 2013. Receiver operating characteristic (ROC) curve analysis was used to determine the optimal cut-off values of the variables for predicting the PDS outcome. We used binary logistic regression to examine the independent predictive value of the factors for incomplete cytoreduction. (3) Among the parameters, we established optimal cut-off values for cancer antigen (Ca)-125, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) to predict the outcome of PDS. The results of binary logistic regression showed that stage (FIGO III-IV), MLR (&gt;0.305), and Ca-125 (&gt;169.15 kU/L) were independent significant predictors of the degree of tumor reduction achieved during PDS. (4) In the future, MLR, especially in combination with other parameters, may be useful in determining prognosis and selecting the best treatment option (PDS or neoadjuvant chemotherapy + interval debulking surgery) for ovarian cancer patients.

Increased Preoperative Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio Are Associated With Major Adverse Events and Mortality After Fenestrated/Branched Endovascular Aortic Repair

The objective was to investigate the role of the preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) as prognostic factors associated with 30-day mortality, major adverse cardiovascular events, acute kidney injury (AKI), and long-term mortality after fenestrated/branched repair (F/BEVAR) of aortic aneurysms with complex anatomy. A retrospective analysis of prospectively collected data of patients who underwent F/BEVAR was performed including cases with a diagnosis of thoracoabdominal aortic aneurysm types I, II, III, IV, and suprarenal and juxtarenal aortic aneurysms. The main inclusion criteria were: (1) complete blood cell count with differential collected within 30 days before surgery and (2) at least 30 days of follow-up. The main exclusion criteria were: (1) comorbid autoimmune/inflammatory diseases and (2) current use of corticosteroid/immunomodulatory drugs. AKI was defined according to the RIFLE (Risk of renal dysfunction, Injury to kidney, Failure or Loss of kidney function, and End-stage kidney disease) criteria. Receiver operating characteristic (ROC) curves were used to determine cutoff values of NLR and PLR associated with the study end points. From 410 patients treated with F/BEVAR between June 2012 and December 2022, 150 were included in the study (70% male; age: 72.7 ± 8.4 years). The mean follow-up time was 29.34 ± 21.79 months. An NLR ≥5 was associated with 30-day mortality with a specificity and sensitivity of 87.1% and 66.7%, respectively, by ROC analysis (Fig 1; area under the ROC curve [AUC] = 0.841, P = .043). The negative predictive value (NPV) was 99.2%. A PLR ≥189 was associated with major adverse cardiovascular events in the first 30-day period with a specificity and sensitivity of 78.8% and 75%, respectively (Fig 2, AUC = 0.830, P = .024), and an NPV of 99.1%. A PLR ≥151 was associated with AKI, with a sensitivity and specificity of 71.4% and 64.3%, respectively (AUC = 0.732, P = .038). The NPV was 97.8%. The groups above and below the cutoffs established by the ROC curves were similar in demographic composition, comorbidities, and extension of the aneurysm. The overall long-term mortality was 27.3% in 5 years. A higher PLR was observed among non-Caucasian patients who died (mean: 190.81 ± 78.4) when compared with the individuals who survived (P = .029). The same finding was not observed in Caucasian patients. Preoperative NLR and PLR are inexpensive and easily available tests that can serve as valuable prognostic tools in patients with complex anatomy aortic aneurysms submitted to F/BEVAR. They might contribute to identifying the higher-risk patients during the preoperative preparation and consequently could indicate which cases would need even more detailed workup before the surgical procedure in the attempt to reduce the odds of adverse events.Fig 2Receiver operating characteristic (ROC) curve for platelet-to-lymphocyte ratio (PLR) considering major adverse cardiovascular event (MACE) during the first 30-day period (P = .024).View Large Image Figure ViewerDownload Hi-res image Download (PPT)

Prognostic value of preoperative serological biomarkers in patients undergoing cytoreductive surgery for ovarian cancer peritoneal metastases.

Peritoneal metastases of ovarian cancer (PMOC) are common at initial presentation. Cytoreductive surgery (CRS) of curative intent has been proven to be efficient in increasing the overall survival (OS) and the disease-free survival (DFS) of these patients. Nevertheless, CRS is associated with high postoperative morbidity, which makes patient selection a major concern. Appropriate prognostic factors that can predict patient outcomes after surgery are still lacking. Preoperative biomarkers and their ratios have been shown to be predictive of patient prognosis for various solid tumors. We aimed to study their correlation with the prognosis of patients undergoing CRS for PMOC. This retrospective study included patients with PMOC operated by CRS. Preoperative biomarkers and other clinicopathological characteristics were studied to determine their prognostic value in terms OS and DFS. 216 patients were included. Patients with preoperative hemoglobin (Hb) <11.7 g/dL had a poorer prognosis in terms of OS (p=0.0062) and DFS (p=0.0077). Additionally, increased neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR) >0.32, and platelet-to-lymphocyte ratio (PLR) >214.5 were associated with worse OS (p=0.022, p=0.0028, and p=0.0018, respectively) and worse DFS (p=0.028, p=0.003, and p=0.019, respectively). Multivariate analysis showed that the variables mentioned above were independent predictive factors for OS and DFS. Preoperative Hb level, NLR, MLR, and PLR are prognostic factors for OS and DFS in PMOC patients operated by curative CRS.

Platelet-to-Lymphocyte Ratio (PLR) as the Prognostic Factor for Recurrence/Residual Disease in HSIL Patients After LEEP.

The platelet-to-lymphocyte ratio (PLR) is considered correlated with cancer prognosis including cervical cancer, in addition to high-risk papillomavirus (HR-HPV) infection, of which the predictive value in prognosis of high-grade squamous intraepithelial lesions (HSILs) remains unknown. Here, the prognostic predictive value of PLR in HSIL after loop electrosurgical excision procedure (LEEP) was evaluated. This study included 335 nonpregnant participants with histopathologically confirmed HSIL and 3- and 5-year follow-ups from the Fujian Cervical Lesions Screening Cohorts (FCLSCs) between September 2016 and September 2018. PLR and other variables were evaluated to identify the factors related to the recurrence/residual cervical intraepithelial neoplasia (CIN)-free survival (RFS), namely, the time from LEEP at baseline to first detection of recurrence/residual CIN or end of follow-up, by logistic and Cox regression. In the Kaplan‒Meier analysis, HR-HPV infection (p=0.049/0.012), higher PLR (p=0.031/0.038), and gland invasion (p=0.047) had a higher risk for recurrence/residual CIN at the 3-/5-year follow-up. The univariate logistic and Cox regression analyses showed significant differences and a higher cumulative risk in patients with HR-HPV infection (OR=3.917, p=0.026; HR=3.996, p=0.020) and higher PLR (OR=2.295, p=0.041; HR=2.161, p=0.030) at the 5-year follow-up. The findings by multivariate Cox regression analysis were similar, indicating a poor prognosis for patients with HR-HPV infection (HR=3.901, p=0.023) and higher PLR (HR=2.082, p=0.038) at the 5-year follow-up. The calibration plot showed a better model fit for RFS at the 3-year follow-up. Preoperative PLR level and HR-HPV infection could be available markers for predicting recurrence/residual disease of HSIL after LEEP. Clinically, combining PLR with HR-HPV tests may provide novel evaluation method and reference for management in post-treatment patients with cervical precancerous lesions.
