The combination of preoperative platelet count and neutrophil lymphocyte ratio as a prognostic indicator in localized renal cell carcinoma

The prognostic value of the haemoglobin/red cell distribution width ratio in a cohort of pre-treated patients with renal cell carcinoma receiving nivolumab

BACKGROUND

Metastatic renal cell carcinoma (mRCC) has a dismal prognosis. Effective prognostic and predictive factors are needed. A higher haemoglobin (Hb) / red cell distribution width (RDW) ratio is known to be related to better outcomes. Here we evaluated the prognostic value of the Hb/RDW ratio in pre-treated mRCC patients receiving nivolumab.

MATERIAL AND METHODS

This is a sub-analysis of the retrospective Meet-URO 15 study, on pre-treated patients with mRCC, receiving nivolumab. The first objective was to investigate the prognostic role of Hb/RDW ratio, in terms of overall survival (OS) and progression-free survival (PFS).

RESULTS

356 were included in the present analysis. Patients were mainly males with a median age of 63 years. We classified patients in high and low Hb/RDW ratio, according to two different cut-offs: 0.9frequently used in literature, and 0.7, result of the time-dependent AUC analysis.. Median OS and PFS were 22.3 months (95 %CI 19.4-29.0) and 5.6 months (95 %CI 4.74.-7.53), respectively. At univariable analysis, higher Hb/RDW ratio was related to longer OS (p < 0.001) and PFS (p = 0.011); the multivariable model confirmed only the association between a Hb/RDW ratio ≥ 0.7 and better OS.

CONCLUSIONS

The Hb/RDW ratio is a manageable and practical prognostic tool in patients with cancer; its prognostic value for OS was confirmed in pre-treated mRCC patients, receiving nivolumab, only using a cut-off value derived from a time-dependent AUC.

Retrospective Clinical Study on Early Prediction of Anastomotic Leak After Esophageal Cancer Resection Based on the Combination of Platelet Count and Neutrophil-to-Lymphocyte Ratio

OBJECTIVE

 The systemic inflammatory response may influence the occurrence of postoperative complications. This study aimed to evaluate the predictive potential of combining platelet count and neutrophil-to-lymphocyte ratio (COP-NLR) for esophagogastric anastomotic leak (AL) following esophageal cancer surgery.

METHODS

 We enrolled patients who developed AL after radical surgery for esophageal cancer and those who did not develop AL after the surgery at the First Affiliated Hospital of Chongqing Medical University, China, from June 2019 to February 2022. We analyzed the correlation between AL and several risk factors, including COP-NLR. Patients were categorized as COP-NLR 2 if both platelet count and neutrophil-to-lymphocyte ratio (NLR) were elevated, COP-NLR 1 if either parameter was elevated, and COP-NLR 0 if neither parameter showed elevation.

RESULTS

 A total of 190 patients were included in this study. The incidence of AL after esophageal cancer surgery was 14.7%. The critical values of preoperative NLR and preoperative platelet count were 2.41 (sensitivity 48.8%, specificity 92.9%, and area under the curve (AUC) 0.728) and 186 × 109/L (sensitivity 45.3%, specificity 78.9%, and AUC 0.667), respectively. According to multivariate analysis, COP-NLR was identified as an independent risk factor for AL (COP-NLR 1 vs. COP-NLR 0: odds ratio (OR) 4.98, 95% confidence interval (CI) 1.05-23.61; COP-NLR 2 vs. COP-NLR 0: OR 11.12, 95% CI 2.31-53.41).

CONCLUSION

 COP-NLR is a new predictor for AL after esophageal cancer resection.

Deciphering RCC immunotherapy outcomes: insights from a Japanese multi-institutional study on the CANLPH score's impact

PURPOSE

The purpose of this study is to determine the utility of the CANLPH score as a predictive biomarker for patients with advanced and metastatic renal cell carcinoma (a/mRCC). By validating its prognostic value, this study aims to contribute to more personalized treatment strategies for a/mRCC.

METHODS

In a multicenter retrospective study by the JK-FOOT consortium, we analyzed data from 309 a/mRCC patients undergoing ICI-based therapy. The CANLPH score-a composite marker of C-reactive protein to albumin ratio (CAR), neutrophil to lymphocyte ratio (NLR), and platelet to hemoglobin ratio (PHR)-for its prognostic accuracy in predicting cancer-specific survival (CSS). Advanced statistical methods, including receiver operating characteristic (ROC) curve analysis, Cox proportional-hazard regression, and Harrell's concordance index (C-index), were employed to assess its predictive capacity against established factors.

RESULTS

The median follow-up period was 17 months, revealing two-year and five-year overall survival rates of 76.8% and 62.4%, respectively, with CSS rates at 78.3% and 66.2%. The CANLPH score well stratified survival outcomes of ICI-based treatment for RCC patients (HR 5.71; P < 0.0001). C-index analysis demonstrated that the CANLPH score had the highest predictive potency for CSS among models, including IMDC score. Multivariate analysis confirmed the CANLPH score (HR, 5.59; P = 0.0007) and Karnofsky performance status (HR, 2.59; P = 0.0032) as independent prognostic factors for CSS.

CONCLUSIONS

The CANLPH score emerges as a critical tool in the a/mRCC therapeutic landscape, enabling precise prediction of patient outcomes with ICI-based therapies. Limitations include the retrospective design and the single national cohort. Prospective validation studies are warranted.

Analysis of surgical site infection and tumour-specific survival rate in patients with renal cell carcinoma after laparoscopic radical nephrectomy

Surgical site infections (SSIs) may pose a significant risk to patients undergoing surgery. This study aims to explore the risk factors for SSIs in patients undergoing laparoscopic radical nephrectomy for renal cell carcinoma and the impact of infection on tumour-specific survival (CSS) after nephrectomy for renal cell carcinoma. To explore the risk factors for SSIs in patients undergoing laparoscopic radical nephrectomy for renal cell carcinoma and the impact of infection on tumour-specific survival (CSS) after nephrectomy for renal cell carcinoma. A retrospective analysis was conducted on 400 patients in our hospital from June 2021 to June 2023. This study divided patients into two groups: those with SSI and those without SSI. Collect general data and information related to the operating room. Clearly defined inclusion and exclusion criteria. Select surgical time, laminar mobile operating room use, and intraoperative hypothermia as observation indicators. Perform statistical analysis using SPSS 25.0 software, including univariate, multivariate, and survival analyses of wound-infected and uninfected patients. Out of 400 patients, 328 had no SSIs, 166 died during follow-up, 72 had SSIs, and 30 died during follow-up. There was no statistically significant difference (p > 0.05) in comparing primary data between individuals without SSIs and those with SSIs. There were statistically significant differences (p < 0.05) in surgical time, nonlaminar flow operating room use, and intraoperative hypothermia. The postoperative survival time of SSI patients with a tumour diameter of 7.0-9.9 cm was significantly longer than that of SSI patients, and the difference was statistically significant (p < 0.05). The occurrence of severe infection in patients with other tumour diameters did not affect postoperative survival, and the difference was not statistically significant (p > 0.05). After multiple factor analysis, it was found that severe infection can prolong the postoperative survival of patients with tumour diameter exceeding 7 cm (HR = 0.749, p < 0.05). This study identified nonlaminar flow operating rooms, prolonged surgical time, and intraoperative hypothermia as significant risk factors for SSIs. After nephrectomy for renal cell carcinoma patients with a tumour diameter of 7-9.9 μ m, perioperative infection can prolong their survival. However, it has no significant effect on patients with other tumour diameters.

Predictive value of SIRI and SII for metastases in RCC: a prospective clinical study

OBJECTIVES

In this prospective cross-sectional clinical study, we aimed to determine the efficiency of preoperative hematological markers namely SIRI (systemic inflammatory response index) and SII (systemic inflammatory index) for renal cell cancer to predict the possibility of postoperative metastases.

METHODS

Istanbul Education and Research Hospital, Clinic of Urology and Medical Oncology in the clinic between the dates of June 2022 to 2023 February, a diagnosis of renal cell cancer by surgical or medical oncology units imported into the treatment planning of 72 patients were included in the study. All cases with diagnoses of renal cell carcinoma were searched from hospital records. Patients with secondary malignancy, hematological or rheumatological disorders or ones with recent blood product transfusion or diagnoses of infection within the 1-month-time of diagnoses were excluded for data analyses. The data within complete blood counts (CBC) analyzed just before the time of renal biopsy or surgery were studied for SIRI and SII calculations. Twenty-two metastatic and 50 non-metastatic RCC patients were included. SIRI and SII values were compared among groups to seek change of values in case of metastasis and in non-metastatic patients a cut-off value were sought to indicate malignancy before pathological diagnosis.

RESULTS

Mean age of non-metastatic RCC patients were 60.12+/-11.55 years and metastatic RCC patients were 60.25+/-11.72. Histological sub-types of the RCC specimens were clear cell (72%), chromophobe cell (17%), papillary cell (7%) and others (4%). Median SIRI values for non-metastatic and metastatic groups were 1.26 and 2.1 (mean+/-S.D. 1.76 +/-1.9 and 3.12+/-4.22 respectively (p < 0.05). Median SII values for non-metastatic and metastatic groups were 566 and 1434 (mean+/-S.D. 870 +/-1019 and 1537+/-917) respectively (p < 0.001). AUC for detection of metastasis were 0.809 for SII and 0.737 for SIRI.

CONCLUSIONS

SIRI and SII indexes seem to show a moderate efficiency to show metastases in RCC.

Prognostic role of systemic inflammation indexes in metastatic urothelial carcinoma treated with immunotherapy

Aims

Inflammation indexes had been associated with overall survival (OS) and immune-related adverse events (irAEs) in patients treated with immune checkpoint inhibitors (ICIs).

Materials & methods

in 72 patients treated with ICIs for metastatic urothelial carcinoma (mUC) we evaluate differences in OS, response rate and toxicities, according to baseline inflammation indexes values.

Results

neutrophil-to-lymphocite ratio (NLR) <3 was associated to longer progression-free survival (PFS; 4.9 vs 3.1 months) and OS (15.7 vs 7.6 months); monocyte-to-lymphocite ratio (MLR) <0.4 was associated to longer PFS (4.6 vs 2.8 months). Overall response rate (ORR), disease control rate (DCR) were higher in these patients. Patients with an irAE had longer PFS and OS.

Conclusion

baseline inflammatory indexes are prognostic for mUC patients treated with ICIs.

The Prognostic Value of Neutrophil-to-Lymphocyte Ratio and Platelet-to-Lymphocyte Ratio for Small Renal Cell Carcinomas after Image-Guided Cryoablation or Radio-Frequency Ablation

There is a lack of cheap and effective biomarkers for the prediction of renal cancer outcomes post-image-guided ablation. This is a retrospective study of patients with localised small renal cell cancer (T1a or T1b) undergoing cryoablation or radiofrequency ablation (RFA) at our institution from 2003 to 2016. A total of 203 patients were included in the analysis. In the multivariable analysis, patients with raised neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) pre-operatively, post-operatively and peri-operatively are associated with significantly worsened cancer-specific survival, overall survival and metastasis-free survival. Furthermore, an increased PLR pre-operatively is also associated with increased odds of a larger than 25% drop in renal function post-operatively. In conclusion, NLR and PLR are effective prognostic factors in predicting oncological outcomes and peri-operative outcomes; however, larger external datasets should be used to validate the findings prior to clinical application.

Novel Retroperitoneal Neovascularity Scoring System in Renal Cell Carcinoma Tumor Staging

Purpose: Renal cell carcinoma (RCC) is the most common type of kidney cancer worldwide. Although radiologists assess enhancement patterns of renal tumors to predict tumor pathology report, to our knowledge, no formal scoring system has been created and validated to assess the level of neovascularity in RCC, despite its critical role in cancer metastases. In this study, we characterized and analyzed the level of angiogenesis in tumor-burdened kidneys and their benign counterparts. We then created and validated a scoring scale for neovascularity that can help predict tumor staging for RCC. Methods: After Institutional Review Board approval, the charts of patients who had undergone operation for RCC between January 13, 2014 and February 4, 2020 were retrospectively reviewed for inclusion in this study. Inclusion criteria were a diagnosis of RCC, simple/radical nephrectomy, preoperative contrast-enhanced CT scans, and complete pathology reports. Neovascularity was scored on a scale of 0-4 where 0 = no neovascularity detected, 1 = a single vessel <3 mm wide, 2 = a single vessel ≥3 mm wide, 3 = multiple vessels <3 mm wide, and 4 = multiple vessels ≥3 mm wide. Results: A total of 227 patients were included in this study. Most of the tumor pathology reports were clear cell carcinoma, regardless of tumor staging. The average neovascularity score was 1.07 for pT1x tumors, 2.83 for pT2x tumors, and 3.04 for pT3x tumors. There was a significant difference in neovascularity score between pT1x and pT2x tumors (p = 0.0046), pT1x and pT3x tumors (p < 0.0001), and benign kidneys and kidneys with RCC (p < 0.0001). Conclusion: Our novel vascular scoring system for RCC demonstrates significant correlation with RCC pathological tumor staging. This scoring system may be utilized as part of a comprehensive radiological assessment of renal tumors, potentially improving tumor characterization and clinical decision making.

Prognostic model for overall survival that includes the combination of platelet count and neutrophil-lymphocyte ratio within the first six weeks of sunitinib treatment for metastatic renal cell carcinoma

BACKGROUND

The association between the combination of platelet count and neutrophil-lymphocyte ratio (COP-NLR) at the time of adverse events during sunitinib treatment and prognosis is unclear, and prognostic models combining the prognostic factors of sunitinib have not been well studied. Thus, we developed a prognostic model that includes the COP-NLR to predict the prognosis of patients with metastatic renal cell carcinoma (mRCC) treated with sunitinib.

METHODS

We performed a retrospective cohort study of 102 patients treated with sunitinib for mRCC between 2008 and 2020 in three hospitals associated with Showa University, Japan. The primary outcome was overall survival (OS). The collected data included baseline patient characteristics, adverse events, laboratory values, and COP-NLR scores within the first 6 weeks of sunitinib treatment. Prognostic factors of OS were analyzed using the Cox proportional hazards model. The integer score was derived from the beta-coefficient (β) of these factors and was divided into three groups. The survival curves were visualized using the Kaplan-Meier method and estimated using a log-rank test.

RESULTS

The median OS was 32.3 months. Multivariable analysis showed that the number of metastatic sites, Memorial Sloan Kettering Cancer Center risk group, number of metastases, non-hypertension, modified Glasgow Prognostic Score, and 6-week COP-NLR were significantly associated with OS. A higher 6-week COP-NLR was significantly associated with a shorter OS (p < 0.001). The β values of the five factors for OS were scored (non-hypertension, mGPS, and 6-week COP-NLR = 1 point; number of metastatic sites = 2 points; MSKCC risk group = 3 points) and patients divided into three groups (≤ 1, 2-3, and ≥ 4). The low-risk (≤ 1) group had significantly longer OS than the high-risk (≥ 4) group (median OS: 99.0 vs. 6.2 months, p < 0.001).

CONCLUSIONS

This study showed that the COP-NLR within the first 6 weeks of sunitinib treatment had a greater impact on OS than the COP-NLR at the start of sunitinib treatment. The developed prognostic model for OS, including the 6-week COP-NLR, will be useful in decision-making to continue sunitinib in the early treatment stage of patients with mRCC.

Serum C-reactive Protein Level Predicts Overall Survival for Clear Cell and Non-Clear Cell Renal Cell Carcinoma Treated with Ipilimumab plus Nivolumab

Serum C-reactive protein (CRP) is known to be a biomarker for systemic inflammatory reactions. In the present study, we sought to measure the predictive value of serum CRP level for metastatic renal cell carcinoma (mRCC) treated with first-line ipilimumab and nivolumab using our real-world clinical dataset including non-clear cell RCC (nccRCC). The clinical record of patients who underwent the first-line ipilimumab plus nivolumab treatment for mRCC including ccRCC and nccRCC from 2018 to 2021 was retrospectively analyzed. All patients were diagnosed with either intermediate or poor-risk group defined by IMCD (international metastatic RCC database consortium). In total, 74 patients were involved. The median age was 68 years and 24 (32.4%) patients deceased during the follow-up. Forty-five (61%) and 29 (39%) patients were classified into intermediate and poor-risk groups. The one-year overall survival (OS) rate and objective response rate were 65% and 41% for all 74 mRCC patients, respectively. The receiver operating characteristic curve identified 1.0 mg/dL of serum CRP level as an ideal cut-off for predicting overall survival (OS). Serum CRP > 1.0 mg/dL and nccRCC were the independent predictors for OS in 74 mRCC patients. OS for patients with CRP > 1 mg/dL was significantly shorter than those with CRP < 1 mg/dL in both ccRCC (58 patient: p = 0.009) and nccRCC (16 patients: p = 0.008). The present study indicated that serum CRP level is a prognostic indicator for OS in both ccRCC and nccRCC patients treated with the first-line ipilimumab plus nivolumab treatment.

Association between preoperative serum Cystatin-C levels and postsurgical oncological prognosis in patients with PRCC: A retrospective cohort study

OBJECTIVE

Cystatin-C (Cys-C) is a predictor of several malignancies. However, whether Cys-C levels predict prognosis in patients with papillary renal cell carcinoma (PRCC) remains uncertain. The aim of this study was to assess the correlation between Cys-C and clinical outcomes in patients with PRCC.

METHODS

The medical records of 137 patients with PRCC who underwent surgery at our institution from January 2008 to December 2020 were retrospectively analyzed. Data were divided into two subgroups based on cutoff values and the relationship between the Cys-C group and their clinical outcomes was assessed.

RESULTS

By the last follow-up, 62 patients had died of various causes, 53 of whom died from PRCC. Sixty patients suffered recurrence or metastasis during follow-up. Based on the cutoff value, the patients were divided into two groups: low Cys-C group (Cys-C < 1.25 mg/L, n = 92) and high Cys-C group (Cys-C ≥ 1.25 mg/L, n = 45). Pathological classification and serum Cys-C levels were shown to be independent prognostic factors affecting clinical outcomes, according to multivariate Cox regression analysis (p < 0.05). After adjusting the Cox proportional hazards model, the risk of death was elevated in the high Cys-C group. The results of the area under the curve for time-dependent receiver operating characteristics analysis indicated that Cys-C is a stable and reliable prognostic biomarker for predicting survival in patients with PRCC. Forest plots, constructed to better reflect the comparison of hazard ratios between the two groups, confirmed that Cys-C levels were significantly associated with worsening overall survival.

CONCLUSION

This study is the first to examine the relationship between preoperative serum Cys-C levels and prognostic overall survival in patients with PRCC. Cys-C may be a useful biomarker for preoperative screening of high-risk patients who may require adjuvant therapy.

Inflammation-Based Score (Combination of Platelet Count and Neutrophil-to-Lymphocyte Ratio) Predicts Pharyngocutaneous Fistula After Total Laryngectomy

OBJECTIVES/HYPOTHESIS

Postoperative complications may depend on the systemic inflammatory response. We evaluated the predictive potential of the combination of platelet count and neutrophil-to-lymphocyte ratio (COP-NLR) for the incidence of pharyngocutaneous fistula (PCF) in patients who have undergone total laryngectomy.

STUDY DESIGN

Retrospective cohort study.

METHODS

Patients who underwent total laryngectomy between 2000 and 2020 were recruited from four hospitals. The correlations between the incidence of PCF and several risk factors, including the COP-NLR, were examined. Patients with both elevated platelet count and elevated neutrophil-to-lymphocyte ratio (NLR) were categorized as COP-NLR 2, and patients with either one or no abnormal values of both parameters were assigned as COP-NLR 1 and COP-NLR 0, respectively.

RESULTS

A total of 235 patients were identified. The overall incidence of PCF was 12.3%. The cut-off value for NLR before surgery was set at 3.95 (sensitivity = 58.6%, specificity = 69.4%, area under the curve [AUC] = 0.635), and the platelet count was set at 320 × 10⁹ /L (sensitivity = 27.6%, specificity = 87.9%, AUC = 0.571). Multivariate analysis revealed that COP-NLR was an independent risk factor for PCF (COP-NLR 1 vs. COP-NLR 0: odds ratio [OR], 4.17; 95% confidence interval [CI], 1.64 to 10.59; and COP-NLR 2 vs. COP-NLR 0: OR, 5.33; 95% CI, 1.38 to 20.56).

CONCLUSIONS

COP-NLR is a novel predictive factor for the development of PCF in patients undergoing total laryngectomy.

Distinct effect of body mass index by sex as a prognostic factor in localized renal cell carcinoma treated with nephrectomy ~ data from a multi-institutional study in Japan ~

Background

We assessed the prognostic value of body mass index (BMI) in Asian patients with localized RCC who underwent nephrectomy.

Methods

A total of 665 patients who underwent nephrectomy for localized RCC were enrolled in the present study and divided into the two BMI groups: i.e., BMI < 25 in 463 (69.6%) and BMI > 25 in 202 (30.4%) patients.

Results

In total, there were 482 (72.5%) males and 183 (27.5%) females. Five-year cancer-specific survival (CSS) rates were significantly higher in increased BMI than the lower BMI group (97.1 and 92.5%: P = 0.007). When stratified by sex, significantly longer CSS in higher BMI was confirmed in males (5-year CSS of 92.7% in BMI < 25 and 98.1% in BMI > 25, p = 0.005), while there was no difference in CSS between BMI groups for female patients. Multivariable analysis exhibited that higher BMI was an independent predictor for favorable CSS in male (cox model: p = 0.041, Fine & Gray regression model: p = 0.014), but not in the female. Subgroup analysis for CSS revealed that favorable CSS with higher BMI was observed in patient subgroups of age < 65 (p = 0.019), clear cell histology (p = 0.018), and tumor size > 4 cm, p = 0.020) as well as male (p = 0.020).

Conclusion

Our findings collected from the multi-institutional Japanese dataset demonstrated longer survival in patients with higher BMI than lower BMI for non-metastatic RCC treated with nephrectomy. Intriguingly, this finding was restricted to males, but not to females.

Is preoperative neutrophil-to-lymphocyte ratio a red flag which can predict high-risk pathological characteristics in renal cell carcinoma?

Introduction

Renal cell carcinoma (RCC) is known to invoke both immunological and inflammatory responses. While the neutrophils mediate the tumor-induced inflammatory response, the lymphocytes bring about the various immunological events associated with it. The neutrophil-to-lymphocyte ratio (NLR) is a simple indicator of this dual response. We investigated the association between preoperative NLR and histopathological prognostic variables of RCC intending to find out whether it can be of value as a red flag capable of alerting the clinician as to the biological character of the tumor under consideration.

Methods

Preoperative NLR and clinicopathological variables, namely histological subtype, nuclear grade, staging, lymphovascular invasion, capsular invasion, tumor necrosis, renal sinus invasion, and sarcomatoid differentiation of 60 patients who underwent radical or partial nephrectomy, were analyzed to detect the association between the two.

Results

We found that mean preoperative NLR was significantly higher in clear-cell carcinomas (3.25 ± 0.29) when compared with nonclear-cell carcinomas (2.25 ± 0.63). There was a linear trend of NLR rise as the stage of the disease advanced. A significant rise in preoperative NLR was noted in tumors with various high-risk histopathological features such as tumor size, capsular invasion, tumor necrosis, and sarcomatoid differentiation.

Conclusion

Preoperative measurement of NLR is a simple test which may provide an early clue of high-risk pathological features of renal cell cancer.

Preoperative Neutrophil-to-Lymphocyte Ratio Was a Predictor of Overall Survival in Small Renal Cell Carcinoma: An Analysis of 384 Consecutive Patients

Objective

The aim of this study was to investigate the prognostic significance of the preoperative neutrophil-to-lymphocyte ratio (NLR) in small renal cell carcinoma (sRCC, ≤4 cm).

Methods

This study was approved by the review board (NO.XYFY2019-KL032-01). Between 2007 and 2016, a total of 384 consecutive patients who underwent curative surgery for sRCC at our institution were evaluated. Patients were divided into high NLR and low NLR groups by plotting the NLR receiver operating characteristic curve. The Kaplan–Meier method was utilized to graphically display survivor functions. Univariate and multivariate Cox proportional hazards regression analysis addressed time to overall survival (OS) and cancer-specific survival (CSS).

Results

Of the 384 patients, 264 (68.8%) were males and 120 (31.2%) were females. Median follow-up time after surgical resection was 54 months. One hundred and eighty-seven (48.7%) patients had a high NLR (≥1.97), and the remaining 197 (51.3%) had a low NLR (<1.97). Patients with high NLR were more likely to be aged compared with patients with low NLR (P=0.028). High NLR was associated with decreased OS and CSS compared with low NLR (P=0.028). High NLR was associated with decreased OS and CSS compared with low NLR (P=0.028). High NLR was associated with decreased OS and CSS compared with low NLR (P=0.028). High NLR was associated with decreased OS and CSS compared with low NLR (

Conclusions

Elevated preoperative NLR is an independent adverse prognostic factor for OS after surgery with curative intent for sRCC.

Prognostic Significance of Pre-surgical Combined Platelet Count and Neutrophil-Lymphocyte Ratio for Patients With Hepatocellular Carcinoma

BACKGROUND/AIM

Recent studies have investigated a novel inflammation-based prognostic system using the combination of platelet count and neutrophil-lymphocyte ratio (COP-NLR). As platelet count decreases with liver damage, we hypothesized that COP-NLR could indicate both inflammation and hepatic reserve in patients with hepatocellular carcinoma (HCC). This study was conducted to clarify the prognostic significance of preoperative COP-NLR in patients with HCC.

PATIENTS AND METHODS

We enrolled 176 patients with histologically-proven HCC who underwent initial curative hepatectomy. Patients were assigned one point each for low platelet count (<15×104/μl) or for high NLR (≥2.0), for hepatic-COP-NLR scores (h-COP-NLR) of 0, 1 or 2.

RESULTS

Five-year overall survival (OS) and recurrence-free survival (RFS) rates were 74.5±9%, and 62.2%±9.3% for score 0, 63.6±5.4% and 50.3%±5.6% for score 1, and 45.2±8.8% and 40.6±8.7% for score 2, respectively, and significantly differed (OS: p=0.01; RFS: p=0.03). In multivariate analysis, h-COP-NLR was an independent risk factor for tumor recurrence (HR=1.39, p=0.03) and death (HR=1.71, p=0.02).

CONCLUSION

h-COP-NLR was an independent predictor for prognosis of HCC patients after hepatic resection.

C-reactive protein/albumin ratio is a predictive factor for prognosis in patients with metastatic renal cell carcinoma

OBJECTIVES

To evaluate the effect of pretreatment C-reactive protein/albumin ratio and modified Glasgow prognostic score on the prognosis in patients with metastatic renal cell carcinoma.

METHODS

A retrospective study was carried out in 176 patients with metastatic renal cell carcinoma who received first-line tyrosine kinase inhibitors. The effect of adding inflammatory prognostic scores to the International Metastatic Renal Cell Carcinoma Database Consortium model (International Metastatic Renal Cell Carcinoma Database Consortium-C-reactive protein/albumin ratio and International Metastatic Renal Cell Carcinoma Database Consortium-Glasgow prognostic score models) on overall survival was evaluated using receiver operating characteristic curves. The prognostic value of inflammatory prognostic scores (C-reactive protein/albumin ratio-modified Glasgow prognostic score) was tested using the Kaplan-Meier method and Cox proportional regression models.

RESULTS

Patients were stratified into two groups using the cut-off value of 0.05: C-reactive protein/albumin ratio-low (<0.05) and C-reactive protein/albumin ratio-high (≥0.05). The area under the curve was significantly higher in the International Metastatic Renal Cell Carcinoma Database Consortium-C-reactive protein/albumin ratio model (0.720) than that of the International Metastatic Renal Cell Carcinoma Database Consortium model (0.689) and the International Metastatic Renal Cell Carcinoma Database Consortium-modified Glasgow prognostic score model (0.703). Significant differences were observed in overall survival stratified by the number of risk factors in the International Metastatic Renal Cell Carcinoma Database Consortium-C-reactive protein/albumin ratio risk model between one or two and three or four factors (P < 0.001), and three or four and five or more factors (P = 0.001). For the patients in the International Metastatic Renal Cell Carcinoma Database Consortium intermediate-risk group, overall survival was significantly different between the C-reactive protein/albumin ratio-low and -high groups (P = 0.001), whereas it was not significantly different between the patients with one and two International Metastatic Renal Cell Carcinoma Database Consortium risk factors (P = 0.106).

CONCLUSION

The C-reactive protein/albumin ratio is a simple and independent predictor of overall survival in patients with metastatic renal cell carcinoma. The predictive activity was significantly improved in the International Metastatic Renal Cell Carcinoma Database Consortium-C-reactive protein/albumin ratio model compared with the International Metastatic Renal Cell Carcinoma Database Consortium/International Metastatic Renal Cell Carcinoma Database Consortium-modified Glasgow prognostic score models.

Leukocyte and platelet counts as prognostic values of testicular germ cell tumours

INTRODUCTION

The immune system plays an essential role in the organism's response to cancer. Several haematological markers can influence prognosis and survival of patients. The objective of this study is to determine their prognostic value in testicular germ cell tumours.

MATERIAL AND METHODS

Retrospective cohort study on 164 patients with germ cell tumours. Clinical, analytical, histological and evolutionary data were collected. The absolute neutrophil and absolute platelet counts, neutrophil-lymphocyte (NLR), platelet-lymphocyte and lymphocyte-monocyte ratios were estimated at diagnosis. The association that these markers can have with the classic prognostic factors, as well as their effect on prognosis and survival, have been analysed.

RESULTS

17.7% had NLR>4 and 14.6% ANC>8000/μL. These patients presented higher percentages of residual disease and stage II-III tumours. Patients with elevated absolute neutrophil showed also higher percentages of progression and exitus. 7.3% presented absolute platelet >400000/μL. These patients obtained higher rates of residual disease, nonseminomatous and stage III tumours. 28.4% showed platelet-lymphocyte values>150. This data was associated to higher percentages of residual disease, progression, stage II and III tumours and seminomatous tumours. 83.3% had an lymphocyte-monocyte >3. These patients presented: higher tumour markers in normal range, decreased residual disease rates and higher percentages of stage I and II tumours. The mean survival time was shorter in patients with NLR>4 and absolute neutrophil >8,000/μL. The ROC curves showed significance in the prediction of progression and values of lymphocyte-monocyte >3, and prediction of survival and values NLR>4.

CONCLUSION

Our results indicate that the analysed haematological markers are associated with poor prognoses at diagnosis. Therefore, their use in daily clinical practice can be a valuable tool in the diagnosis and prognosis of patients with testicular germ cell tumours.

The CANLPH Score, an Integrative Model of Systemic Inflammation and Nutrition Status (SINS), Predicts Clinical Outcomes After Surgery in Renal Cell Carcinoma: Data From a Multicenter Cohort in Japan

BACKGROUND

A myriad of studies have demonstrated the clinical association of systemic inflammatory and nutrition status (SINS) including C-reactive protein/albumin ratio (CAR), the neutrophil/lymphocyte ratio (NLR), and the platelet/hemoglobin ratio (PHR). This study aimed to investigate the predictive value of the score integrating these variables (CANLPH) in patients with renal cell carcinoma (RCC).

METHODS

Using cohort data from a multi-institutional study, 757 of 1109 patients were retrospectively analyzed. The optimal cutoff value for outcome prediction of continuous variables in CAR, NLR, and PHR was determined and the CANLPH score was then calculated as the sum score of 0 or 1 by the cutoff value in each ratio.

RESULTS

The median follow-up time was 76 months for the patients who survived (n = 585) and 31 months for those who died (n = 172). The Youden Index offered an optimal cutoff of 1.5 for CAR and 2.8 for NLR, and a higher value from the cutoff was assigned as a score of 1. The cutoff value of the PHR was defined as 2.1 for males and 2.3 for females. The patients were assigned a CANLPH score of 0 (47.2%), 1 (31.3%), 2 (13.1%), or 3 (8.5%). In the multivariate analysis, the CANLPH score served as an independent predictor of cancer-specific mortality in both localized and metastatic RCC.

CONCLUSION

The score was well-correlated with clinical outcome for the RCC patients. Because this score can be concisely measured at the point of diagnosis, physicians may be encouraged to incorporate this model into the treatment for RCC.

The Role of Neutrophil-Lymphocyte Ratio, Platelet-Lymphocyte Ratio, and Platelets in the Prognosis of Metastatic Renal Cell Carcinoma

OBJECTIVE(S)

The aim of this analysis was to evaluate the platelet-lymphocyte ratio (PLR), neutrophil-lymphocyte ratio (NLR), platelets (PLT), and neutrophil level for their prognostic value in patients with metastatic renal cell carcinoma (mRCC).

MATERIALS

We retrospectively reviewed medical records of 141 patients with mRCC (2006-2016). Univariate and multivariate analyses were performed with the Cox proportional hazards regression model. The cutoff value of NLR was "elevated" as >3.68 and the PLR cutoff value was "elevated" as >144.4.

RESULTS

The median PFS and OS were shorter in elevated NLR and PLR. A higher value of PLT was associated with worse median OS and higher neutrophil level with worse OS and PFS. In multivariate analysis, higher NLR (p = 0.007) and PLR (p = 0.006) were independent prognostic factors for shorter OS together with BMI ≤30 (p = 0.004), higher Fuhrman grade (p = 0.0002), lower level of hemoglobin (p= 0.010), and ZUBROD 2 (p = 0.0002). Higher PLR (p = 0.0002) was an independent negative prognostic factor for PFS together with higher Fuhrman grade (p = 0.001), higher neutrophil level (p = 0.001), and lower lymphocyte level (p = 0.013).

CONCLUSION

Elevated pretreatment NLR, PLR, PLT, and neutrophil count are associated with shorter OS and PFS in patients with mRCC. NLR and PLR are independent prognostic factors for OS. However, PLR and neutrophil count are independent prognostic factors for PFS.

Discovery of lipid biomarkers correlated with disease progression in clear cell renal cell carcinoma using desorption electrospray ionization imaging mass spectrometry

Clear cell renal cell carcinoma (ccRCC) often results in recurrence or metastasis, and there are only a few clinically effective biomarkers for early diagnosis and personalized therapy. Metabolic changes have been widely studied using mass spectrometry (MS) of tissue lysates to identify novel biomarkers. Our objective was to identify lipid biomarkers that can predict disease progression in ccRCC by a tissue-based approach. We retrospectively investigated lipid molecules in cancerous tissues and normal renal cortex tissues obtained from patients with ccRCC (n = 47) using desorption electrospray ionization imaging mass spectrometry (DESI-IMS). We selected eight candidate lipid biomarkers showing higher signal intensity in cancerous than in normal tissues, with a clear distinction of the tissue type based on the images. Of these candidates, low maximum intensity ratio (cancerous/normal) values of ions of oleic acid, m/z 389.2, and 391.3 significantly correlated with shorter progression-free survival compared with high maximum intensity ratio values (P = 0.011, P = 0.022, and P < 0.001, respectively). This study identified novel lipid molecules contributing to the prediction of disease progression in ccRCC using DESI-IMS. Our findings on lipid storage may provide a new diagnostic or therapeutic strategy for targeting cancer cell metabolism.
