Albumin-to-fibrinogen ratio as a promising biomarker to predict clinical outcome of non-small cell lung cancer individuals.
Chronic inflammation is one of the critical causes to promote the initiation and metastasis of solid malignancies including lung cancer (LC). Here, we aimed to investigate the prognostic roles of albumin (Alb)-to-fibrinogen (Fib) ratio (AFR), Fib and Alb in LC and to establish a novel effective nomogram combined with AFR. Four hundred twelve LC patients diagnosed between February 2005 and December 2014 were recruited in this prospective study. The prognostic roles of AFR, Fib, Alb, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and monocyte-to-lymphocyte ratio (MLR) were identified by X-tile software, Kaplan-Meier curve, Cox regression model, and time-dependent ROC. Pretreatment high circulating Fib, low AFR, and Alb were significantly associated with increased risk of death for LC patients, especially for non-small cell lung cancer (NSCLC) patients in all stages. The area under curves (AUCs) of AFR, Fib, and NLR were higher than them within Alb and PLR for predicting the survival of NSCLC patients. Moreover, we found that clinical outcome of high AFR patient with chemo-radiotherapy was superior to low AFR patient; overall survival rate of stage II-III NSCLC patients undergoing chemo-radiotherapy was significantly lower than the surgical patients with treatment of adjuvant chemo-radiotherapy(P = 0.001) in low AFR subgroup. On the contrary, clinical outcome of the patients receiving chemo-radiotherapy was the same to the patients undergoing surgery and adjuvant chemo-radiotherapy (P = 0.405) in high AFR subgroup. In addition, c-index of predicted nomogram including AFR (0.717) for NSCLC patients with treatment of chemo-radiotherapy was higher than that without AFR (0.707). Our findings demonstrated that circulating pretreatment AFR might be a potential biomarker to predict clinical efficacy of surgical resection and adjuvant chemo-radiotherapy and be a prognostic biomarker for NSCLC individuals.

Prognostic significance of pre-resection albumin/fibrinogen ratio in patients with non-small cell lung cancer: A propensity score matching analysis.
Nutrition and coagulation play important roles in cancer progression. This study was aimed to investigate the value of the albumin/fibrinogen ratio (AFR) in non-small cell lung cancer (NSCLC) patients, through a propensity score matching (PSM) method.
We retrospectively analyzed 529 NSCLC patients underwent surgical resection from 2010 to 2015. PSM was used to eliminate possible biases. A Cox proportional hazards regression model was performed to evaluate the prognostic value of AFR in NSCLC.
The optimal value was 9.67 for the AFR by ROC (receiver operating characteristic) curve. The AFR was statistically significantly associated with age, sex, smoking history, histological subtype, tumor size, pathological stage and adjuvant therapy (p < 0.05). Multivariate analysis indicated that the pathological stage and pre-resection AFR were independent prognostic factors for patients with NSCLC. Additionally, elevated AFR indicated a better outcome, and patients with higher AFR had lower risk for overall death (OS) (HR 0.512, 95% CI 0.316-0.829, p = 0.006) as well as disease-free death (DFS) (HR 0.561, 95% CI 0.399-0.787, p = 0.001). The propensity score model identified 120 patients from each group that were balanced for age, sex, smoking history, histological subtype, tumor size, stage distribution and adjuvant therapy. In multivariable regression analysis of PSM groups, the result indicated that the AFR was predictive for OS (HR 0.392, 95% CI 0.225-0.683, p < 0.001) and DFS (HR 0.526, 95% CI 0.344-0.805, p = 0.003).
Pre-resection AFR can be considered as an independent prognostic factor in NSCLC patients, and higher AFR may enhance OS and DFS of NSCLC patients.

The Role of Cancer-Elicited Inflammatory Biomarkers in Predicting Early Recurrence Within Stage II-III Colorectal Cancer Patients After Curable Resection.
Smoldering cancer-related inflammation attenuates chemotherapy efficacy and contributes to unsatisfactory outcome for patients of colorectal cancer (CRC). Various inflammation-based biomarkers were reported to predict the survival of the disease, however, it remains unclear which is the best inflammation-based biomarker. The aim of present study was to compare the prognostic role of those biomarkers and to establish superior survival score for post-recurrence survival in radically operative patients with stage II-III CRC.
Preoperative peripheral neutrophil, lymphocyte, monocyte, platelet, serum albumin (Alb), pre-Alb, and plasma fibrinogen (Fib) were detected in the discovery and validation cohort which included a total of 1533 stage II-III surgical CRC patients. We calculated and compared fourteen inflammation-based biomarkers for predicting recurrence-free survival (RFS) of the patients with stage II-III CRC.
In this study, the platelet to lymphocyte ratio (PLR), lymphocyte to monocyte (LMR), systemic inflammation response index (SIRI), prognostic nutritional index (PNI), systemic immune-inflammation index (SII), modified systemic inflammation score (mSIS), fibrinogen and neutrophil to lymphocyte ratio score (F-NLR), ratio of Alb to Fib (AFR), and ratio of Fib to pre-Alb (FPR) were all related to the RFS of the patients in both discovery and validation cohorts, however, only the LMR, SIRI, PNI, mSIS, F-NLR, AFR and FPR remained independent predictors for RFS in multivariate analysis. Both the C-index of the FPR (0.629 for 36 months) and the areas under the time-dependent receiver operating characteristic (ROC) curves (0.625 for 12 months, 0.641 for both 24 and 0.637 months) showed that it was superior to the other inflammation-based prognostic scores for predicting the RFS of stage II-III surgical CRC patients. Moreover, elevated FPR was significantly associated with unsatisfactory RFS regardless of TNM stage and primary tumor location. Stage II low FPR patients showed the best RFS regardless of chemotherapy. The better RFS was observed in chemotherapy-treated stage II high FPR patients than those without the treatment, and the outcomes of patients with treatment of XELOX, capecitabine and XELOX were superior to the other regimens to treat patients in stage III low- and high-FPR populations, respectively. Additionally, the carcinoembryonic antigen (CEA)-FPR combined score one (adjusted HR=2.764, 95% CI=2.129-3.589) and two (adjusted HR=3.543, 95% CI=2.317-5.420) were extremely associated with RFS of these patients, and the predicted AUC of the combined score for 12, 24 and 36 months were 0.657, 0.657 and 0.653 in stage II-III patients, which were superior to the single CEA and FPR, respectively.
In conclusion, FPR is superior to the other inflammatory biomarkers as a useful recurrence indicator in stage II-III surgical CRC patients in terms of prognostic ability; it helps to choose the effective chemotherapy regimen and to increase the predicted efficacy of CEA and the combined CEA and FPR score could effectively predict recurrence of the patients.
