Preoperative neutrophil:lymphocyte and platelet:lymphocyte ratios predict endometrial cancer survival

Background:

Variations in systemic inflammatory response biomarker levels have been associated with adverse clinical outcome in various malignancies. This study determined the prognostic significance of preoperative neutrophil:lymphocyte (NLR), platelet:lymphocyte (PLR) and monocyte:lymphocyte (MLR) ratios in endometrial cancer.

Methods:

Clinicopathological and 5-year follow-up data were obtained for a retrospective series of surgically treated endometrial cancer patients (n=605). Prognostic significance was determined for overall (OS) and cancer-specific survival (CSS) using Cox proportional hazards models and Kaplan–Meier analysis. Receiver–operator characteristic and log-rank functions were used to optimise cut-offs. NLR, PLR and MLR associations with clinicopathological variables were determined using non-parametric tests.

Results:

Applying cut-offs of ⩾2.4 (NLR), ⩾240 (PLR) and ⩾0.19 (MLR), NLR and PLR (but not MLR) had independent prognostic significance. Combining NLR and PLR scores stratified patients into low (NLR-low and PLR-low), intermediate (NLR-high or PLR-high) and high risk (NLR-high and PLR-high) groups: multivariable hazard ratio (HR) 2.51; P<0.001 (OS); HR 2.26; P<0.01 (CSS) for high vs low risk patients. Increased NLR and PLR were most strongly associated with advanced stage (P<0.001), whereas increased MLR was strongly associated with older age (P<0.001).

Conclusion:

Both NLR and PLR are independent prognostic indicators for endometrial cancer, which can be combined to provide additional patient stratification.     

Nomograms for predicting prognostic value of inflammatory biomarkers in colorectal cancer patients after radical resection

Increasing evidence indicates that inflammation plays a vital role in tumorigenesis and progression. However, the prognostic value of inflammatory biomarkers in colorectal cancer (CRC) has not been established. In this study, a retrospective analysis was conducted in patients with CRC in Fudan University Shanghai Cancer Center (FUSCC) between April 1, 2007 and April 30, 2014, and 5,336 patients were identified eligible. Neutrophil‐to‐lymphocyte ratio (NLR), platelet‐to‐lymphocyte ratio (PLR), lymphocyte‐to‐monocyte ratio (LMR), and albumin/globulin ratio (AGR) were analyzed. Kaplan‐Meier analysis was used to calculate the 5‐year overall survival (OS) and disease‐free survival (DFS). Cox regression analysis was performed to assess the prognostic factors. Nomograms were established to predict OS and DFS, and Harrell's concordance index (c‐index) was adopted to evaluate prediction accuracy. As results, the 5‐year OS was 79.2% and the 5‐year DFS was 56.0% in the cohort. Patients were stratified into 2 groups by NLR (≤2.72 and >2.72), PLR (≤219.00 and >219.00), LMR (≤2.83 and >2.83) and AGR (<1.50 and ≥1.50). Patients with NLR > 2.72, PLR > 219.00, LMR ≤ 2.83 and AGR < 1.50 were significantly associated with decreased OS and DFS (p < 0.001). Multivariate analysis indicated that NLR, LMR and AGR were independent factors of OS (p = 0.047, p = 0.008 and p < 0.001, respectively) and DFS (p = 0.009, p < 0.001 and p = 0.008, respectively). In addition, nomograms on OS and DFS were established according to all significant factors, and c‐indexes were 0.765 (95% CI: 0.744–0.785) and 0.735 (95% CI: 0.721–0.749), respectively. Nomograms based on OS and DFS can be recommended as practical models to evaluate prognosis for CRC patients.

Combination of platelet count and neutrophil to lymphocyte ratio is a useful predictor of postoperative survival in patients with colorectal cancer

Background:

This study investigated the usefulness of a novel inflammation-based prognostic system, named the COP-NLR (COmbination of Platelet count and Neutrophil to Lymphocyte Ratio), for predicting the postoperative survival of patients with colorectal cancer (CRC).

Methods:

The COP-NLR was calculated on the basis of data obtained on the day of admission: patients with both an elevated platelet count (>30 × 10⁴ mm⁻³) and an elevated NLR (>3) were allocated a score of 2, and patients showing one or neither were allocated a score of 1 or 0, respectively.

Results:

Four-hundred and eighty patients were enrolled. Multivariate analysis of clinical characteristics selected by univariate analysis showed that the COP-NLR (1, 2/0) (odds ratio, 0.464; 95% confidence interval, 0.267–0.807; P=0.007) had an association with cancer-specific survival, along with pathology, lymph node metastasis, the serum levels of carcinoembryonic antigen, C-reactive protein and albumin, and the Glasgow Prognostic Score. Kaplan–Meier analysis and log-rank test revealed that the COP-NLR was able to divide such patients into three independent groups (P<0.001).

Conclusion:

The COP-NLR is considered to be a useful predictor of postoperative survival in patients with CRC.     

Neutrophil‐lymphocyte ratio at diagnosis is an independent prognostic factor in patients with nodular sclerosis Hodgkin lymphoma: results of a large multicenter study involving 990 patients

Several studies have demonstrated the prognostic value of neutrophil‐lymphocyte ratio (NLR) in patients with solid tumors and non–Hodgkin lymphoma. In contrast, there is only sparse data on its prognostic role in patients with classical Hodgkin lymphoma (cHL). The aim of our study was to establish whether NLR could serve as an independent prognostic factor in a cohort of 990 patients with nodular sclerosis (NS)‐cHL. After analysis of the log hazard ratio (HR) as a function of NLR, we chose the value 6 as cutoff. Patients with NLR >6 had a worse progression‐free survival and overall survival compared to those with NLR ≤6; 84% vs 75% and 92% vs 88%, at 5 years, with an HR of 1.65 and 1.82, respectively. Multivariate analysis showed that the risk remained high with HR 1.44 and HR 1.54 in progression‐free survival and overall survival, respectively. In summary, our study shows that NLR is a robust and independent prognostic parameter in NS‐cHL, both in early and advanced disease. It is inexpensive and simple to apply. Thus, we conclude that NLR, possibly in combination with the international prognostic score and absolute monocyte count, is a useful guide for physicians treating NS‐cHL patients.     

Roles of Neutrophil/Lymphocyte and Platelet/Lymphocyte Ratios in the Early Diagnosis of Malignant Ovarian Masses

Background: The present study aimed to investigate the utility and importance of the various parameters of complete blood count panel for benign-malignant differentiation of adnexal masses. Materials and Methods: This retrospective study involved 316 patients with documented benign and 253 patients with malignant adnexal masses who underwent primary surgical treatment at a tertiary referral center. Prior to the study, all benign and malignant cases were compared within their own groups and then the benign and malignant cases were compared to each other. For all cases, cut-off, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for the neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), neutrophil, lymphocyte, platelet and CA-125 parameters, and the results were compared in regards to the groups. Results: NLR, PLR, neutrophil, CA-125, and platelet values were higher in the malignant compared to the benign cases (p<0.01). The lymphocyte value was lower in the malignant cases (p<0.01). No significantdifferences were found for basophils and eosinophils (p > 0.05). For CA-125, the sensitivity, specificity, PPV and NPV for all cases were 78%, 62%, 62% and 78%, respectively. For NLR, they were 65.6%, 72.1%, 65.3%, and 72.3%, and for PLR, 48%, 81%, 67%, and 66%. Additionally, the sensitivity and specificity were 55% and 77% for CA-125, 66% and 58% for NLR, and 61% and 58% for PLR in early malignant cases. Conclusions: NLR and PLR appear to be useful methods that can be applied together with CA-125 due to the relatively high sensitivity values for the malign-benign differentiation of ovarian masses. Although the specificity of these parameters is lower than CA-125, especially in cases with early malignant ovarian pathology, their sensitivity being higher is promising for the early diagnosis of ovarian cancer. It can be used to detect ovarian malignancies in the early stages, and it will increase the treatment options and improve survival rates.     

外周血NLR和PLR在接受免疫治疗肿瘤患者中的预后价值

持续的全身慢性炎症在恶性肿瘤的发生、进展、转移过程中起着重要作用。外周血中性粒细胞与淋巴细胞比值(neutrophil-to-lymphocyte ratio,NLR)和血小板与淋巴细胞比值(platelet-to-lymphocyte ratio,PLR)与多种恶性肿瘤如肺癌、恶性黑色素瘤、消化道恶性肿瘤、肝癌等免疫治疗的预后具有显著相关性,同时NLR和PLR检测具有价格低、创伤小、易获得、可重复性高的特点。研究表明,较高的基线或用药后NLR和PLR水平与患者对免疫治疗的反应、预后均呈负相关,且患者出现免疫治疗抵抗、肿瘤进展或死亡的风险更高,预期无进展生存期(progression free survival,PFS)、总生存期(overall survival,OS)相较于低NLR和低PLR患者更短。该文就NLR和PLR与多种接受免疫治疗的恶性肿瘤患者预后的相关研究作一综述,为寻找针对免疫治疗的最佳预后指标、早期筛选出免疫治疗潜在获益患者以及预测他们的治疗结局提供依据。     

The prognostic impact of the neutrophil-to-lymphocyte ratio in patients with small-cell lung cancer

Background:

The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are prognostic factors for various types of cancer. In this study, we assessed the association of NLR and PLR with the prognosis of small-cell lung cancer (SCLC) in patients who received the standard treatment.

Methods:

We retrospectively reviewed patients who were diagnosed with SCLC and treated with platinum-based chemotherapy between July 2006 and October 2013 in Gyeongsang National University Hospital Regional Cancer Center and Changwon Samsung Hospital.

Results:

In total, 187 patients were evaluated. Compared with low NLR (<4), high NLR (⩾4) at diagnosis was associated with poor performance status, advanced stage, and lower response rate. Median overall survival (OS) and progression-free survival (PFS) were worse in the high-NLR group (high vs low, 11.17 vs 9.20 months, P=0.019 and 6.90 vs 5.49 months, P=0.005, respectively). In contrast, PLR at diagnosis was not associated with OS or PFS (P=0.467 and P=0.205, respectively). In multivariate analysis, stage, lactate dehydrogenase, and NLR at diagnosis were independent prognostic factors for OS and PFS.

Conclusions:

NLR is easily measurable and reflects the SCLC prognosis. A future prospective study is warranted to confirm our results.
