Pretreatment plasma fibrinogen as an independent prognostic indicator of prostate cancer patients treated with androgen deprivation therapy

Fibrinogen and tumors

Elevated plasma fibrinogen (Fg) levels consistently correlate with an unfavorable prognosis in various tumor patient cohorts. Within the tumor microenvironment, aberrant deposition and expression of Fg have been consistently observed, interacting with multiple cellular receptors and thereby accentuating its role as a regulator of inflammatory processes. Specifically, Fg serves to stimulate and recruit immune cells and pro-inflammatory cytokines, thereby contributing to the promotion of tumor progression. Additionally, Fg and its fragments exhibit dichotomous effects on tumor angiogenesis. Notably, Fg also facilitates tumor migration through both platelet-dependent and platelet-independent mechanisms. Recent studies have illuminated several tumor-related signaling pathways influenced by Fg. This review provides a comprehensive summary of the intricate involvement of Fg in tumor biology, elucidating its multifaceted role and the underlying mechanisms.

The Utility of Inflammatory Serum Markers in the Assessment of Perioperative Morbidity after Radical Cystectomy for Bladder Cancer

Background and Objectives: To date, sparse evidence exists about the impact of inflammatory serum markers in predicting perioperative complications after radical cystectomy (RC) for bladder cancer (BC). Here, we evaluated the role of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), C-reactive protein (CRP), and plasma fibrinogen in predicting perioperative morbidity and unplanned 30-days readmission after RC for BC. Materials and methods: We relied on a collaborative database of 271 patients who underwent open RC for cT1-4a N0 M0 BC between January 2012 and December 2022. Univariable and multivariable binomial logistic regression analyses were performed to assess the odds ratio (OR) with 95% confidence intervals (CI) testing the ability of each serum marker to predict postoperative complications (any-grade and major complications), and 30-days unplanned readmission. Results: The median age at RC was 73 yr (IQR 67-79). A total of 182 (67.2%) patients were male and the median BMI was 25.2 (IQR 23.2-28.4). Overall, 172 (63.5%) patients had a Charlson Comorbidity Index (CCI) greater than 2 points and 98 (36.2%) were current smokers at the time of RC. Overall, 233 (86.0%) patients experienced at least one complication after RC. Of these, 171 (63.1%) patients had minor complications (Clavien-Dindo grade 1-2) while 100 (36.9%) experienced major complications (Clavien-Dindo grade ≥ 3). According to multivariable analysis, current smoking status, high plasma fibrinogen, and preoperative anemia were independently associated with major complications (OR 2.10, 95%CI 1.15-4.90, p = 0.02), (OR 1.51, 95%CI 1.26-1.98, p = 0.09), and (OR 1.35, 95%CI 1.17-2.57, p = 0.03), respectively. Overall, 56 (20.7%) patients experienced a 30-days unplanned readmission. According to univariable analysis, high preoperative CRP and hyperfibrinogenemia were significantly associated with an increased risk of unplanned readmission (OR 2.15, 95%CI 1.15-4.16, p = 0.02; OR 2.18, 95%CI 1.13-4.44, p = 0.02, respectively). Conclusions: In our study, the preoperative immune-inflammation signature described by NLR, PLR, LMR, SII, and CRP showed a low reliability in predicting perioperative course after RC. Preoperative anemia and hyperfibrinogenemia were independent predictors of major complications. Further studies are pending in order to draw definitive conclusions.

Prognostic value of hematological pre-albumin to fibrinogen ratio in patients with glioma

OBJECTIVE

Hematological biomarkers that reflect host nutritional and inflammation status have been identified to be independent prognostic factors in various malignancies. The aim of the present study was to determine the predictive value of preoperative albumin (ALB), fibrinogen (FIB), pre-albumin (pALB), Albumin to fibrinogen ratio (AFR) and pre-albumin to fibrinogen ratio (PFR) for the prognosis of patients with glioma.

METHOD

X-tile software was used to identify cut-off values of these parameters. Kaplan-Meier survival analysis, univariate and multivariate analyses based on Cox proportional hazards regression model were used to determine whether these markers were associated with the prognosis of patients with glioma. In addition, the Harrell concordance index with variables was used to evaluate the prognostic accuracy.

RESULTS

The results indicated that PFR (HR = 2.827, 95% CI: 1.353-6.122, p = 0.006) is the only independent prognostic factor in patients of glioma along with clinicopathological grade and age. C-index of predicted nomogram including PFR (0.719) for glioma patients was higher than that without PFR (0.699).

CONCLUSIONS

Our findings demonstrated that circulating preoperative PFR might be a potential negative independent prognostic biomarker for glioma individuals.

Combined Longitudinal Clinical and Autopsy Phenomic Assessment in Lethal Metastatic Prostate Cancer: Recommendations for Advancing Precision Medicine

BACKGROUND

Systematic identification of data essential for outcome prediction in metastatic prostate cancer (mPC) would accelerate development of precision oncology.

OBJECTIVE

To identify novel phenotypes and features associated with mPC outcome, and to identify biomarker and data requirements to be tested in future precision oncology trials.

DESIGN SETTING AND PARTICIPANTS

We analyzed deep longitudinal clinical, neuroendocrine expression, and autopsy data of 33 men who died from mPC between 1995 and 2004 (PELICAN33), and related findings to mPC biomarkers reported in the literature.

INTERVENTION

Thirty-three men prospectively consented to participate in an integrated clinical-molecular rapid autopsy study of mPC.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Data exploration with correction for multiple testing and survival analysis from the time of diagnosis to time to death and time to first occurrence of severe pain as outcomes were carried out. The effect of seven complications on the modeled probability of dying within 2 yr after presenting with the complication was evaluated using logistic regression.

RESULTS AND LIMITATIONS

Feature exploration revealed novel phenotypes related to mPC outcome. Four complications (pleural effusion, severe anemia, severe or controlled pain, and bone fracture) predict the likelihood of death within 2 yr. Men with Gleason grade group 5 cancers developed severe pain sooner than those with lower-grade tumors. Surprisingly, neuroendocrine (NE) differentiation was frequently observed in the setting of high serum prostate-specific antigen (PSA) levels (≥30 ng/ml). In 4/33 patients, no controlled (requiring analgesics) or severe pain was detected, and strikingly, 14/15 metastatic sites studied in these men did not express NE markers, suggesting an inverse relationship between NE differentiation and pain in mPC. Intracranial subdural metastasis is common (36%) and is usually clinically undetected. Categorization of "skeletal-related events" complications used in recent studies likely obscures the understanding of spinal cord compression and fracture. Early death from prostate cancer was identified in a subgroup of men with a low longitudinal PSA bandwidth. Cachexia is common (body mass index <0.89 in 24/31 patients) but limited to the last year of life. Biomarker review identified 30 categories of mPC biomarkers in need of winnowing in future trials. All findings require validation in larger cohorts, preferably alongside data from this study.

CONCLUSIONS

The study identified novel outcome subgroups for future validation and provides "vision for mPC precision oncology 2020-2050" draft recommendations for future data collection and biomarker studies.

PATIENT SUMMARY

To better understand variation in metastatic prostate cancer behavior, we assembled and analyzed longitudinal clinical and autopsy records in 33 men. We identified novel outcomes, phenotypes, and aspects of disease burden to be tested and refined in future trials.

Prognostic value of preoperative albumin-to-fibrinogen ratio (AFR) in patients with bladder cancer treated with radical cystectomy

INTRODUCTION AND OBJECTIVES

To evaluate the prognostic role of albumin-to-fibrinogen ratio (AFR) for the prediction of oncological outcomes in a multi-institutional cohort of bladder cancer (BC) patients treated with radical cystectomy (RC).

MATERIALS AND METHODS

We retrospectively analyzed a multicenter cohort of patients treated with upfront RC for localized (cT1-4aN0M0) BC. Multivariable logistic regression analyses were performed to evaluate the ability of AFR to predict non-organ confined (NOC) disease and lymph-node involvement (LNI) at time of RC. Multivariable Cox' regression models were performed to evaluate the prognostic effect of AFR on Time-to-Progression (TTP), overall survival (OS), and cancer-specific survival (CSS).

RESULTS

A cut-off value to discriminate between low and high AFR was determined by calculating the receiver operating characteristic (ROC) curve. The area under the curve was 0.73 with an optimal cut-off at 9.53. Data were available for 246 patients (91 with low AFR, 155 with high AFR). Low AFR was associated with characteristics of tumor aggressiveness and independently predicted NOC (OR 2.11, P = 0.02) and LNI (OR 1.58, P = 0.04) at final pathological report. On multivariable Cox' regression analyses, preoperative low AFR was independently associated with worse TTP (HR 2.21, P = 0.02), OS (HR 2.24, P = 0.03), and CSS (HR 2.70, P = 0.01).

CONCLUSION

Preoperative low AFR is a prognostic biomarker for worse TTP, OS, CSS, and is independently associated with adverse tumor pathological features in BC patients undergoing RC. Our results suggest that especially patients with low AFR may be considered for neoadjuvant treatment.

Elevated Serum FGG Levels Prognosticate and Promote the Disease Progression in Prostate Cancer

Castration-resistant prostate cancer (CRPC) threatens the health of men in general and no effective therapeutics currently exists for the treatment of CRPC. It is therefore of great importance to find a novel molecule that can be a biomarker and a therapeutic target for CRPC. First, we found that the serum fibrinogen gamma (FGG) levels in patients with CRPC were significantly higher than those with localized prostate cancer (PCa) through iTRAQ proteomics and ELISA experiments. Immunohistochemistry, quantitative real-time polymerase chain reaction and western blot also showed an increase of FGG expression in CRPC tissues and cells. Then we proved the proliferation, invasion and migration ability of CRPC cells were significantly reduced after FGG knockdown. The number of apoptotic cells increased at least sixfold after FGG silencing, and was observed in conjunction with an upregulation of p53, caspase 3, clea-caspase 3, and Bax, and a downregulation of Bcl2 and survivin. FGG knockdown in DU145 cells resulted in smaller xenografts than control cells in a mouse model. and we established that FGG is modulated by IL-6 which was increased in CRPC patients via phosphorylation of STAT3. The data suggests that FGG may be a potential therapeutic target and prognostic marker for CRPC.

Pretreatment elevated fibrinogen level predicts worse oncologic outcomes in upper tract urothelial carcinoma

This study aimed to further validate the prognostic role of fibrinogen in upper tract urothelial carcinoma (UTUC) in a large Chinese cohort. A total of 703 patients who underwent radical nephroureterectomy were retrospectively identified. Fibrinogen levels of ≥4.025 g l⁻¹ were defined as elevated. Logistic regression analysis was performed to determine the association between fibrinogen and adverse pathological features. Kaplan–Meier analysis and Cox regression models were used to assess the associations of fibrinogen with cancer-specific survival (CSS), disease recurrence-free survival (RFS), and overall survival (OS). Harrell c-index and decision curve analysis were used to assess the clinical utility of multivariate models. The median follow-up duration was 42 (range: 1–168) months. Logistic regression analysis revealed that elevated fibrinogen was associated with higher tumor stage and grade, lymph node involvement, lymphovascular invasion, sessile carcinoma, concomitant variant histology, and positive surgical margins (all P < 0.05). Multivariate Cox regression analysis demonstrated that elevated fibrinogen was independently associated with decreased CSS (hazard ratio [HR]: 2.33; P < 0.001), RFS (HR: 2.09; P < 0.001), and OS (HR: 2.09; P < 0.001). The predictive accuracies of the multivariate models were improved by 3.2%, 2.0%, and 2.8% for CSS, RFS, and OS, respectively, when fibrinogen was added. Decision curve analysis showed an added benefit for CSS prediction when fibrinogen was added to the model. Preoperative fibrinogen may be a strong independent predictor of worse oncologic outcomes in UTUC; therefore, it may be valuable to apply this marker to the current risk stratification in UTUC.

Systemic Coagulation Markers Especially Fibrinogen Are Closely Associated with the Aggressiveness of Prostate Cancer in Patients Who Underwent Transrectal Ultrasound-Guided Prostate Biopsy

Objective

It has been well elucidated that multiple types of cancers are at high risk of thrombosis. Several studies have indicated the prognostic value of fibrinogen (Fib) and D-dimer (DD) in prostate cancer (PCa). However, it remains unclear regarding the association of the comprehensive coagulation markers with the clinicopathological features of PCa.

Methods

A total of 423 pathologically diagnosed patients with PCa were consecutively collected and stratified as low-intermediate-risk or high-risk groups. The association of coagulation parameters including Fib, DD, prothrombin (PT), activated partial thromboplastin time (APTT), thrombin time (TT), and antithrombin III (AT-III) with clinicopathological features was determined by univariate and multivariate logistic regression analyses.

Results

The levels of Fib, DD, and PT were significantly higher in the high-risk group (p < 0.001, p < 0.001, and p = 0.043, resp.), while APTT, TT, and AT-III were similar between two groups (p > 0.05, all). Univariate logistic regression analysis demonstrated that Fib, DD, and PT were all positively correlated with high-risk PCa (OR = 2.041, p < 0.001; OR = 1.003, p < 0.001; OR = 1.247, p = 0.044). Nonetheless, after adjusting for PSA, grade, and stage, Fib (T3 vs. T1, OR = 15.202, 95% CI: 1.725-133.959, p = 0.014) but not DD or PT was the unique independent factor associated with high-risk PCa in the multivariate regression analysis.

Conclusions

Our study firstly revealed that Fib but other coagulation markers was independently associated with the severity of PCa, suggesting Fib might be useful in PCa risk stratification beyond PSA, stage, and grade.

Prognostic Significance of Preoperative Fibrinogen-to-Prealbumin Ratio in Patients with Stage I-III Colorectal Cancer Undergoing Surgical Resection: A Retrospective Cohort Study

Background

The objective of this study was to explore the role of preoperative fibrinogen-to-prealbumin ratio (FPR) in evaluating the prognosis of patients with stage I–III colorectal cancer (CRC).

Methods

This retrospective study enrolled 584 stage I–III CRC patients undergoing surgical resection. Logistic regression analysis was used to explore the correlation between FPR and postoperative complications. The Kaplan-Meier curve and Cox proportional hazards model were used to identify the prognostic factors. The nomograms were constructed based on the prognostic factors. The concordance index and calibration curve were used to determine the accuracy of the nomograms. Time-dependent receiver operating characteristic was used to compare the predictive prognostic efficacy of nomograms and TNM stage.

Results

FPR was determined to be an independent factor affecting postoperative complications. Patients with a low-FPR had a significantly better prognosis than those with a high-FPR (disease-free survival, p = 0.028; overall survival, p = 0.027), especially patients with stage I CRC (disease-free survival, p = 0.015; overall survival, p = 0.017). The Cox proportional hazards model identified FPR as an independent poor prognostic factor of disease-free survival (hazard ratio (HR) = 1.459, 95% confidence interval (CI) = 1.074–1.954, p = 0.011) and overall survival (HR = 1.405, 95% CI = 1.034–1.909, p = 0.030). The prognostic nomograms had good accuracy and were superior to the traditional TNM stage.

Conclusions

FPR is a potential indicator for predicting short- and long-term prognosis of stage I–III CRC patients undergoing surgical resection.

The predictive value of the preoperative fibrinogen-albumin ratio on the postoperative prognosis of renal cell carcinoma

Background

Urologists urgently need a simple, effective, accurate clinical biomarker to identify renal cell carcinoma (RCC) patients with poor prognosis and those with a high risk of recurrence as early as possible. Therefore, we investigated the prognostic value of the preoperative fibrinogen-albumin ratio (FAR) in patients with RCC.

Methods

We retrospectively analyzed data from 279 cases of renal cancer admitted to the First Hospital of Peking University from 2010 to 2012. The best cutoff value of the FAR was obtained using receiver operating characteristic (ROC) curve analysis, and patients were divided into high- and low-FAR groups. The correlation between the preoperative FAR and clinicopathological features was analyzed by χ² test. Log-rank test and Cox proportional hazard regression model were used to evaluate the predictive value of clinicopathological parameters for overall survival (OS).

Results

The best cutoff value for the FAR was 0.116. A FAR >0.116 was associated with higher Fuhrman grade (P<0.0001) and later pathological T stage (P<0.0001). Patients with a high FAR (>0.116) had worse OS [hazard ratio (HR) 10.497, 95% confidence interval (CI): 3.263–33.766, P<0.0001]. In multivariate analysis, the FAR was an independent risk factor for OS (HR 5.047, 95% CI: 2.109–12.076, P=0.003). Moreover, in Fuhrman grade I–II patients, the FAR could distinguish patients with worse prognosis (P<0.0001).

Conclusions

The preoperative FAR is an independent prognostic factor of OS in renal cancer patients. A FAR >0.116 was significantly related to decreased survival in renal cancer patients.

Pretreatment elevated prognostic nutritional index predicts a favorable prognosis in patients with prostate cancer

Background

The prognostic nutritional index (PNI), an immunity and nutrition based prognostic score, was correlated with clinical outcomes in different tumors. However, the prognostic significance of PNI has not been investigated in hormone sensitive prostate cancer (PCa). The objective of this study was to determine the prognostic significance of PNI in hormone sensitive PCa.

Methods

Two hundred eighty PCa patients undergoing androgen deprivation therapy (ADT) as first line therapy at three centers were enrolled. The serum albumin levels and peripheral lymphocyte count were measured at the time of diagnosis. PNI was calculated as 10 * serum albumin (g/dL) + 0.005 * total lymphocyte count (per mm3). Patients were categorized in two groups using a cut-off point of 50.2 as calculated by the receiver-operating curve analysis. Univariate and multivariate cox regression analyses were performed to evaluate PNI as a favorable prognostic factor for progression-free survival (PFS), cancer-specific survival (CSS) and overall survival (OS). Prognostic accuracy was evaluated with the Harrell concordance index.

Results

Multivariate analyses identified PNI as an independent prognostic indicator with respect to PFS (hazard ratio (HR) = 0.521, p = 0.001), CSS (HR = 0.421, p = 0.002) and OS (HR = 0.429, p = 0.001). Patients with elevated PNI had better clinical outcomes. The addition of PNI to the final models improved predictive accuracy (c-index: 0.758, 0.830 and 0.782) for PFS, CSS and OS compared with the clinicopathological base models (c-index: 0.736, 0.801 and 0.752), which included Gleason score and incidence of metastasis.

Conclusions

Elevated pretreatment PNI was a favorable prognostic indicator for PCa patients treated with ADT.

Clinical association between pre-treatment levels of plasma fibrinogen and bone metastatic burden in newly diagnosed prostate cancer patients

BACKGROUND

Due to the different treatments for low-volume metastatic prostate cancer (PCa) as well as high-volume ones, evaluation of bone metastatic status is clinically significant. In this study, we evaluated the correlation between pre-treatment plasma fibrinogen and the burden of bone metastasis in newly diagnosed PCa patients.

METHODS

A single-center retrospective analysis, focusing on prostate biopsies of newly diagnosed PCa patients, was performed. A total of 261 patients were enrolled in this study in a 4-year period. All subjects were submitted to single-photon emission computerized tomography-computed tomography to confirm the status of bone metastasis and, if present, the number of metastatic lesions would then be calculated. Clinical information such as age, prostate-specific antigen (PSA), fibrinogen, clinical T stage, and Gleason score were collected. Patients were divided into three groups: (i) a non-metastatic group, (ii) a high volume disease (HVD) group (>3 metastases with at least one lesion outside the spine), and (iii) a low volume disease (LVD) group (metastatic patients excluding HVD ones). The main statistical methods included non-parametric Mann-Whitney test, Spearman correlation, receiver operating characteristic (ROC) curves, and logistic regression.

RESULTS

Fibrinogen positively correlated with Gleason score (r = 0.180, P = 0.003), PSA levels (r = 0.216, P < 0.001), and number of metastatic lesions (r = 0.296, P < 0.001). Compared with the non-metastatic and LVD groups, the HVD group showed the highest PSA (104.98 ng/mL, median) and fibrinogen levels (3.39 g/L, median), as well as the largest proportion of Gleason score >7 (86.8%). Both univariate (odds ratio [OR] = 2.16, 95% confidential interval [CI]: 1.536-3.038, P < 0.001) and multivariate (OR = 1.726, 95% CI: 1.206-2.472, P = 0.003) logistic regressions showed that fibrinogen was independently associated with HVD. The ROC curve suggested that fibrinogen acts as a predictor of HVD patients, yielding a cut-off of 3.08 g/L, with a sensitivity of 0.684 and a specificity of 0.760 (area under the curve = 0.739, 95% CI: 0.644-0.833, P < 0.001).

CONCLUSIONS

Pre-treatment plasma fibrinogen is positively associated with bone metastatic burden in PCa patients. Our results indicate that fibrinogen might be a potential predictor of HVD.

Preoperative Plasma Fibrinogen and D-dimer as Prognostic Biomarkers for Non-Muscle-Invasive Bladder Cancer

PURPOSE

To assess the ability of preoperative plasma fibrinogen and D-dimer as biomarkers to predict survival outcomes in patients with non-muscle-invasive bladder cancer (NMIBC).

PATIENTS AND METHODS

A total of 206 NMIBC patients receiving transurethral resection of bladder tumor (TURBT) were assessed in our retrospective study. The cutoff values of fibrinogen and D-dimer were determined using receiver operating characteristic curve analysis. Cox regression analyses were adopted to assess the influence of these two parameters on recurrence-free survival (RFS) and progression-free survival (PFS).

RESULTS

The cutoff values of fibrinogen and D-dimer were 3.56 g/L and 0.48 μg/mL, respectively. Kaplan-Meier analysis demonstrated that high fibrinogen and D-dimer levels were significantly related to poor RFS (all P < .001) and PFS (all P < .001). Moreover, patients with elevated fibrinogen levels tended to have high tumor grade (P = .033), advanced pathologic T stage (P < .001), and multiple tumor lesions (P = .019). Significant associations of high D-dimer levels with advanced pathologic T stage (P = .026), large tumor size (P = .012), and multiple tumor lesions (P = .006) were found. In addition, multivariate analysis revealed that plasma fibrinogen and D-dimer were all independent predictive factors for RFS (P = .029 and .001, respectively) and PFS (P = .023 and .003, respectively).

CONCLUSION

High levels of preoperative plasma fibrinogen and D-dimer may indicate advanced clinicopathologic features and worse prognosis, suggesting that these two coagulation parameters could be used as prognostic biomarkers for NMIBC patients.

Systemic immune-inflammation index, serum albumin, and fibrinogen impact prognosis in castration-resistant prostate cancer patients treated with first-line docetaxel

PURPOSE

To evaluate the prognostic value of pretreatment plasma systemic immune-inflammation index (SII), albumin, and fibrinogen levels in metastatic castration-resistant prostate cancer (mCRPC) patients treated with first-line docetaxel and to screen out the patients with the greatest risk for poor prognosis.

METHODS

The plasma SII, albumin, and fibrinogen levels were examined before treatment and analyzed with patient clinicopathological parameters and overall survival (OS). The survival analysis was performed using the Kaplan-Meier method, and prognostic factors were assessed using the Cox proportional hazard regression model.

RESULTS

The incidences of elevated SII level, hypoproteinemia, and hyperfibrinogenemia were 52.51%, 25.14%, and 27.93%, respectively. SII level was associated with neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) (P < 0.001). Albumin level was found closely correlated with ECOG PS (P = 0.006), PLR (P = 0.042), and hemoglobin (P = 0.009), but not other parameters. Elevated plasma fibrinogen level was significantly associated with Eastern Cooperative Oncology Group performance status (ECOG PS) (P = 0.009), visceral metastases (P < 0.001), and PLR (P = 0.001). In multivariate Cox regression model, visceral metastases SII (HR 2.133, 95% CI 1.163-3.913; P = 0.014), albumin (HR 0.540, 95% CI 0.307-0.949; P = 0.032), and fibrinogen (HR 1.888, 95% CI 1.069-3.335; P = 0.029) were further confirmed to be the independent prognostic factors for OS. Of the three target parameters, we found that patients with none abnormalities of the three parameters showed the best prognosis, and patients with at least any two abnormalities of them showed markedly worse prognosis than patients with any one abnormalities of the three parameters (P < 0.001).

CONCLUSIONS

Pretreatment SII, albumin, and fibrinogen are independent prognostic factors in mCRPC patients treated with first-line docetaxel. Moreover, the combined use of SII, albumin, and fibrinogen levels may help us to identify the high-risk populations for treatment decisions.

The Prognostic Value of Pretreatment Plasma Fibrinogen in Urological Cancers: A Systematic Review and Meta-analysis

Objective: Growing evidence suggests pretreatment fibrinogen can serve as a prognostic marker in various malignancies. However, there are contradictory results about the prognostic role of fibrinogen in urological cancers. We conducted a meta-analysis to evaluate the association between pretreatment plasma fibrinogen and survival outcomes in urological cancers. Methods: After a systematic search of PubMed and Embase, we included 14 studies in our meta-analysis, and estimated hazard ratios (HRs) for overall survival (OS) and cancer-specific survival (CSS) using a fixed-effect model. Results: Our results indicate that pretreatment plasma fibrinogen is a prognostic factor in urological cancers (OS: HR=2.21, 95% CI=1.91-2.57, P<0.001, CSS: HR=2.67, 95% CI=2.23-3.19, P<0.001). Elevated pretreatment plasma fibrinogen is associated with poorer survival in prostate cancer (OS: HR=2.26, 95% CI=1.47-3.48, P<0.001; CSS: HR=2.42, 95% CI=1.44-4.07, P=0.001), renal cell carcinoma (OS: HR=2.13, 95% CI=1.75-2.61, P<0.001; CSS: HR=2.99, 95% CI=2.29-3.89, P<0.001) and upper tract urothelial carcinoma (OS: HR=2.34, 95% CI=1.81-3.02, P<0.001; CSS: HR=2.43, 95% CI=1.84-3.20, P<0.001). Subgroup analyses showed that plasma fibrinogen has a more negative impact on survival in Caucasian patients (OS: HR=2.52, 95% CI=1.95-3.25, P<0.001; CSS: HR=2.83, 95% CI=1.92-4.17, P<0.001) than Asian patients (OS: HR=2.07, 95% CI=1.73-2.49, P<0.001; CSS: HR=2.63, 95% CI=2.14-3.22, P<0.001). The prognostic value of fibrinogen is also consistent when stratified by different cut-off values. Conclusions: These results show that high pretreatment plasma fibrinogen levels can predict poorer OS and CSS in patients with urological cancers.

Circulating fibrinogen to pre-albumin ratio is a promising biomarker for diagnosis of colorectal cancer

BACKGROUND

Inflammation and nutrition are closely associated with initiation and progression of colorectal cancer (CRC). This study aimed to investigate the diagnostic value of the FAR (FAR = 100*Fibrinogen/Albumin) and FPR (FPR = Fibrinogen/pre-Albumin) in CRC.

METHODS

Neutrophil-to-lymphocyte ratio (NLR), FPR, and FAR were calculated in 455 newly diagnosed CRC patients, 455 healthy individuals, and 455 benign controls with colorectal polyp. The diagnostic value of biomarker for CRC was evaluated by receiver operating characteristic curve (ROC). Logistic regression analysis was adopted to assess the risk factors for telling CRC apart from benign disease. Moreover, the combined biomarkers were used for discriminating between CRC and benign disease.

RESULTS

Neutrophil-to-lymphocyte ratio, FAR, and FPR were significantly higher in CRC patients compared with the benign or healthy controls (P < 0.05). ROC analysis showed that the diagnostic efficacy of FAR and FPR were better than NLR for CRC. Besides, FPR, NLR, carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9 (CA199) were markedly associated with differentiation of benign disease and CRC in the logistic regression analysis. And the combination of FPR, CEA, and CA199 had the maximum area under the ROC curve (AUC) in separating CRC from benign disease (AUC = 0.845, Sensitivity = 67.9%, Specificity = 85.3%, Positive Predictive Value = 83.5%, Negative Predictive Value = 70.9%).

CONCLUSIONS

Fibrinogen/pre-Albumin could be a useful CRC diagnostic biomarker, and the combination of FPR, CEA, and CA199 could significantly improve the diagnostic efficacy in discriminating CRC from the benign colorectal disease.

Prognostic value of selected preoperative inflammation-based scores in patients with high-risk localized prostate cancer who underwent radical prostatectomy

Background

This study investigated the prognostic value of inflammation-based scores in patients with high-risk localized prostate cancer who underwent radical prostatectomy with or without neoadjuvant androgen deprivation therapy (ADT).

Methods

Inflammation-based scores included the neutrophil-to-lymphocyte ratio (NLR), derived NLR (dNLR), platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), and plasma fibrinogen. A total of 440 patients (380 patients treated without neoadjuvant ADT and 60 patients treated with neoadjuvant ADT) were retrospectively evaluated in our medical center. Receiver operating characteristic (ROC) curves and Kaplan-Meier analyses were performed to compare the prognostic value of these scores. Univariate and multivariate Cox regression analyses were also performed.

Results

For all patients, dNLR and PNI were predictive of biochemical recurrence (.=0.041 and <0.001, respectively). Subgroup analysis of neoadjuvant strategies was also performed. For patients treated with neoadjuvant ADT, no selected inflammation-based scores were significantly correlated with biochemical recurrence (.>0.05). In contrast, for patients treated without neoadjuvant ADT, NLR (area under the ROC curve [AUC] =0.576, P=0.033), dNLR (.=0.585 and 0.017), PLR (AUC =0.582, P=0.024), and PNI (AUC =0.622, P<0.001) were predictive of biochemical recurrence. Kaplan-Meier analyses showed that dNLR (.=0.044), PLR (.=0.028), and PNI (.=0.004) were significantly associated with biochemical recurrence. Based on multivariable models, PNI was an independent predictor of biochemical recurrence (hazard ratio: 0.56, 95% confidence interval: 0.35-0.90, P=0.016).

Conclusion

High dNLR, high PLR, and low PNI were associated with poor biochemical recurrence-free survival in patients undergoing radical prostatectomy for high-risk localized prostate cancer not treated with neoadjuvant ADT. In particular, PNI was an independent prognostic factor for biochemical recurrence.

Markers of Inflammation and Incident Breast Cancer Risk in the Women's Health Study

Chronic inflammation may be a risk factor for the development and progression of breast cancer, yet it is unknown which inflammatory biomarkers and pathways are especially relevant. The present study included 27,071 participants (mean age = 54.5 years) in the Women's Health Study who were free of cancer and cardiovascular disease at enrollment (1992-1995), with baseline measures of 4 inflammatory biomarkers: high-sensitivity C-reactive protein, fibrinogen, N-acetyl side-chains of acute phase proteins, and soluble intercellular adhesion molecule-1. We used Cox proportional hazards regression models to evaluate associations between baseline concentrations of biomarkers and incident breast cancer, and adjusted for baseline and time-varying factors such as age and body mass index. Self-reported invasive breast cancer was confirmed against medical records for 1,497 incident cases (90% postmenopausal). We observed different patterns of risk depending on the inflammatory biomarker. There was a significant direct association between fibrinogen and breast cancer risk (for quintile 5 vs. quintile 1, adjusted hazard ratio = 1.25, 95% confidence interval: 1.03, 1.51; P for trend = 0.01). In contrast, soluble intercellular adhesion molecule-1 was inversely associated with breast cancer (for quintile 5 vs. quintile 1, adjusted hazard ratio = 0.79, 95% confidence interval: 0.66, 0.94; P for trend = 0.02). N-acetyl side-chains of acute phase proteins and high-sensitivity C-reactive protein were not associated with breast cancer. The complex association of chronic inflammation and breast cancer may be considered when formulating anti-inflammatory cancer prevention or intervention strategies.

Albumin and Fibrinogen Combined Prognostic Grade Predicts Prognosis of Patients with Prostate Cancer

Background: The nutritional status and systemic inflammation are thought to be associated with outcome in multiple types of cancer. The objective of this study was to determine the prognostic value of pretreatment albumin and fibrinogen combined prognostic grade (AFPG) in prostate cancer (PCa). Methods: 462 prostate cancer patients who had undergone androgen deprivation therapy (ADT) as first-line therapy at four cencters were retrospectively analyzed. The serum albumin levels and plasma fibrinogen levels were measured at the time of diagnosis. The AFPG was calculated according to albumin and fibrinogen levels dichotomized by optimal cut-off values or clinical reference values. Univariate and multivariate cox regression analyses were performed to determine the associations of AFPG with progression-free survival (PFS), cancer-specific survival (CSS) and overall survival (OS). Prognostic accuracy was evaluated with the Harrell concordance index. Results: Multivariate analyses identified AFPG as an independent prognostic indicator for PFS, CSS and OS (each p < 0.01). According to optimal cut-off values, the addition of AFPG to the final models improved predictive accuracy for PFS, CSS and OS compared with the clinicopathological base models, which included Gleason score and incidence of metastasis. Moreover, AFPG according to optimal cut-off values was a better prognostic predictor than albumin levels alone or fibrinogen levels alone or AFPG according to clinical reference values. Conclusion: Decreased AFPG could predict a significantly poor prognosis in patients with PCa. Thus, we recommend adding AFPG according to optimal cut-off values to traditional prognostic model to improve the predictive accuracy.

Tools for Predicting Clinical and Patient-reported Outcomes in Prostate Cancer Patients Undergoing Androgen Deprivation Therapy: A Systematic Review of Prognostic Accuracy and Validity

Androgen deprivation therapy (ADT) can result in a range of adverse symptoms that reduce patients' quality of life. Careful patient counseling on the likely clinical outcomes and adverse effects is therefore vital. The present systematic review was undertaken to identify and characterize all the tools used for the prediction of clinical and patient-reported outcome measures (PROMs) in patients with prostate cancer undergoing ADT. PubMed and EMBASE were systematically searched from 2007 to 2016. Search terms related to the inclusion criteria were: prostate cancer, clinical outcomes, PROMs, ADT, and prognosis. Titles and abstracts were reviewed to find relevant studies, which were advanced to full-text review. The reference lists were screened for additional studies. The Centre for Evidence Based Medicine critical appraisal of prognostic studies tool was applied. The search strategy identified 8755 studies. Of the 8755 studies, 22 on clinical outcomes were identified. However, no studies of PROMs were found. Nine tools could be used to predict clinical outcomes in treatment-naive patients and 10 in patients with recurrence. The Japan Cancer of the Prostate Risk Assessment (J-CAPRA) nomogram was the best performing and validated tool for the prediction of clinical outcomes in treatment-naive patients, and the Chi and Shamash prognostic indexes have been validated for use in patients with castration-resistant disease in different clinical contexts. Using the J-CAPRA nomogram should help clinicians deliver accurate, evidence-based counseling to patients undergoing primary ADT. A strong need exists for primary studies that derive and validate tools for the prediction of PROMs in patients undergoing ADT under any circumstance because these are currently absent from the literature.
