Preoperative plasma fibrinogen level is a risk factor for the long-term survival of postmenopausal women after surgery for breast cancer

BackgroundStudies have indicated an association between fibrinogen levels and the prognosis of breast cancer patients. However, fibrinogen levels are notably susceptible to fluctuations due to the menstrual cycle. This study explored the relationship between preoperative plasma fibrinogen levels and the prognosis of postmenopausal breast cancer women after surgery. Method855 patients with postmenopausal breast cancer were monitored for 10 years. Cox proportional hazards regression models were used to perform univariate and multivariate analyses to identify factors that are of substantial prognostic value. ResultsThe median follow-up was 77 months (51–105 months), and the maximum 142 months. Over the follow-up period, 65 deaths (7.6 %) were recorded. Multivariate Cox regression results show that preoperative plasma fibrinogen level (hazard ratio [HR] =1.615, 95 % confidence interval [CI]: 1.233–2.115) and age (HR = 1.626, 95%CI: 1.250–2.116) were independent risk factors for 10-year overall survival after surgery in postmenopausal breast cancer patients, while endocrine therapy (HR = 0.414, 95%CI: 0.202–0.846) was an independent protective factor. Multivariate Cox regression results also show preoperative plasma fibrinogen level was an independent risk factor for 10-year disease-free survival (HR = 1.398, 95 % CI: 1.137–1.719) and 10-year distant metastasis-free survival (HR = 1.436, 95%CI: 1.153–1.787). ConclusionElevated pretreatment plasma fibrinogen levels are associated with a poorer long-term prognosis in postmenopausal breast cancer patients following surgical treatment.

Prognostic value of neutrophil-to-lymphocyte ratio and fibrinogen levels in ovarian cancer

BACKGROUND High neutrophil-to-lymphocyte ratio (NLR) and fibrinogen levels have been associated with mortality in several malignancies. However, the studies on the association between NLR or fibrinogen levels and ovarian cancer prognosis are inconsistent. This study aimed to investigate the prognostic roles of NLR and fibrinogen in ovarian cancer.
 METHODS A systematic search of electronic databases was performed to analyze studies on the association of pre-treatment NLR and fibrinogen levels with overall survival (OS) and progression-free survival (PFS) among patients with ovarian cancer. The hazard ratio (HR) and corresponding 95% confidence intervals [CIs] were analyzed. All statistical analyses were done using RevMan version 5.4 (Cochrane, United Kingdom).
 RESULTS A total of 7,312 patients from 27 studies were included. The median cut-off for high NLR was 3.6 for OS among 17 studies and 3.23 for PFS among 11 studies reporting an NLR HR. The median cut-off for fibrinogen levels was 4.0 in 9 studies reporting fibrinogen levels HR. High NLR was associated with lower OS (HR 1.35, 95% CI 1.18 to 1.55, p<0.0001, I2 = 76%) and PFS (HR 1.35, 95% CI 1.14 to 1.60, p = 0.0005, I2 = 71%). High fibrinogen levels were associated with lower OS (HR 1.44, 95% CI 1.14 to 1.82, p = 0.002, I2 = 81%) and PFS (HR 1.34, 95% CI 1.17 to 1.55, p<0.0001, I2 = 15%). This association occurred in all ovarian cancer types.
 CONCLUSIONS High pre-treatment NLR and plasma fibrinogen levels were related to poor OS and PFS in ovarian cancer.

494 Low plasma fibrinogen levels are associated with poor prognosis in cutaneous angiosarcoma of the head and neck

Angiosarcomas are malignant vascular tumors that account for 2% of all soft-tissue sarcomas. Due to the rarity of angiosarcomas, the prognostic factors are seldom reported. Here, we investigated plasma fibrinogen levels as a prognostic factor for angiosarcoma of the head and neck (ASHN). This retrospective study reviewed a cohort of patients histologically diagnosed with ASHN at Nagoya University Hospital between April 2006 and July 2019. The 22 patients with ASHN included in the present study. The cutoff value of plasma fibrinogen levels was determined to be 257 mg/dL. The Kaplan–Meier curve showed the OS rate to be significantly higher in the high plasma fibrinogen group than in the low plasma fibrinogen group (p=0.0027). The univariable model showed that patients with low plasma fibrinogen levels had a significantly poor OS [hazard ratio 6.78, 95% confidence interval 1.63 to 28.2, p-value of 0.008503]. Recently, high plasma fibrinogen levels were reported to predict poor prognosis in several malignancies. Unexpectedly, the present study suggests that low plasma fibrinogen levels predict poor prognosis. ASHN is an extremely hemorrhagic tumor. From repeated microbleeds and blood coagulation in ASHN lesions, plasma fibrinogen is considered to be consumed and to decrease in patients with ASHN. Therefore, we speculate that the reduced plasma fibrinogen levels might reflect tumor burden indirectly. In conclusion, the present study suggests that pre-treatment plasma fibrinogen levels are a useful prognostic factor for ASHN that may reflect tumor burden.

Pretreatment plasma fibrinogen and serum albumin levels predict therapeutic efficacy of concurrent radiochemotherapy for esophageal squamous cell cancer.

PurposeEvidence implies that plasma fibrinogen and serum albumin level (FA score) based on plasma fibrinogen and serum albumin is related to cancer prognosis. However, the association between the FA score and therapeutic efficacy of concurrent radiochemotherapy in esophageal squamous cell carcinoma (ESCC) has not yet been evaluated. This study aimed to assess the role of pretreatment FA score in predicting the therapeutic efficacy of concurrent radiochemotherapy for patients with esophageal squamous cell cancer.MethodsThis retrospective study evaluated 154 patients with ESCC who underwent concurrent radiochemotherapy. Receiver operating characteristic curve (ROC) analysis was used to determine the appropriate cut-off values, and multivariate analysis and Kaplan-Meier curve were used to evaluate prognosis.ResultsFA score was significantly associated with the N stage and M stage (P = 0.015 and 0.042, respectively). Chi-square analysis/Fisher’s exact tests revealed a correlation between the FA score and curative effect (P < 0.001), and higher FA score was associated with poorer treatment effect. Multivariate analysis indicated that FA score (P < 0.001) was predictor of overall survival (OS). Kaplan-Meier curve demonstrated that pretreatment FA score was significantly associated with the OS of ESCC: Patient with higher FA score has lower median OS.ConclusionsThe FA score is a reliable prognostic predictor that could assess the curative effect and OS benefit of concurrent radiochemotherapy in patients with ESCC.

Plasma fibrinogen acts as a predictive factor for pathological complete response to neoadjuvant chemotherapy in breast cancer: a retrospective study of 1004 Chinese breast cancer patients

BackgroundThe aim of this study was to evaluate the relationship between pre-treatment plasma fibrinogen (Fib) level and pathological complete response (pCR) to neoadjuvant chemotherapy (NAC) in breast cancer patients and to assess the role of plasma Fib as a predictive factor.MethodsData from 1004 consecutive patients with invasive breast cancer who received NAC and subsequent surgery were retrospectively analysed. Both univariate and multivariate analyses based on logistic regression model were performed to identify clinicopathological factors associated with pCR to NAC. Cox regression model was used to determine the correlation between clinical or pathological parameters and recurrence-free survival (RFS). The Kaplan-Meier method and the log-rank test were applied in the survival analysis.ResultsThe median value of Fib, rather than other plasma coagulation parameters, was significantly increased in non-pCR patients compared with pCR patients (P = 0.002). Based on the cut-off value estimated by the receiver operating characteristic (ROC) curve analysis, patients were divided into low or high Fib groups (Fib < 3.435 g/L or ≥ 3.435 g/L). Low Fib levels were significantly associated with premenopausal or perimenopausal status (P < 0.001), tumour size ≤5 cm (P = 0.002), and positive hormone receptor status (P = 0.002). After adjusted for other clinicopathological factors in the multivariate logistic regression model, low Fib status was strongly associated with pCR to NAC (OR = 3.038, 95% CI 1.667–5.537, P < 0.001). Survival analysis showed that patients with low Fib levels exhibited better 3-year RFS compared with patients with high Fib levels in the tumour size>5 cm group (77.5% vs 58.4%, log-rank, P = 0.0168).ConclusionsThis study demonstrates that low pre-treatment plasma Fib (Fib < 3.435 g/L) is an independent predictive factor for pCR to NAC in breast cancer patients. Moreover, T3-featured breast cancer patients with lower Fib level exhibit better RFS outcomes after NAC compared with high Fib status.

Elevated pretreatment plasma fibrinogen level is associated with metastasis of non-small cell lung cancer (NSCLC)

Abstract Objective The aim of this study was to investigate the correlation between pretreatment fibrinogen levels and metastasis in non-small cell lung cancer (NSCLC). Methods The study included 503 NSCLC patients with a clear pathological diagnosis and 168 patients diagnosed with benign lung diseases by histological examination. Pretreatment plasma fibrinogen values were quantified, and the relationship between plasma fibrinogen level and clinical variables comprising tumor size, metastasis, and clinical stage was examined using Kruskal-Wallis test, Wilcoxon rank sum test, and Chi-square test. Results The median plasma fibrinogen values were statistically higher in NSCLC patients with metastasis than patients with benign lung diseases and NSCLC patients without metastasis (Kruskal-Wallis test; P &lt; 0.001). Plasma fibrinogen values were also significantly higher in advanced clinical stages (Wilcoxon rank sum test; P &lt; 0.001). A significant relationship was observed between elevated fibrinogen (&gt; 2.974 g/L) and metastasis, clinical stage, and tumor size (Chi-square test; P &lt; 0.001). Conclusion This correlation suggests that elevated pretreatment plasma fibrinogen levels can predict metastasis and advanced tumor stage in NSCLC patients.

Platelet count as a biomarker for monitoring treatment response and disease recurrence in recurrent epithelial ovarian cancer

ObjectivesWe sought to determine the impact of pretreatment plasma platelet levels, dimerized plasmin fragment (D-dimer) and fibrinogen in recurrent epithelial ovarian cancer (EOC) and the impact of platelet levels on SKOV3 cell lines growth and responsiveness to chemotherapy.MethodsUnder approval of ethical committee, we identified 104 women with recurrent EOC who underwent treatment between January 2010 and February 2015. Reviewing clinical, laboratory, and pathologic records from this retrospective cohort, we analyzed the correlation between pretreatment plasma D-dimer, fibrinogen, platelet levels and clinicopathological parameters, progression free survival (PFS) and overall survival (OS). Inco-culture experiments human ovarian cancer SKOV3 cell lines were used to test the effect of platelet levels on tumor growth and responsiveness to docetaxel.ResultsOf the 104 recurrent EOC, thrombocytosis at diagnosis and the decrease of platelet count by less than 25% after primary therapy were associated with worse median progression free survival (P = 0.003;P = 0.021) and median overall survival (P = 0.009;P = 0.009). Mean platelet levels declined at the end of primary therapy(P < 0.001) and rose at recurrence(P = 0.007). In multivariate analysis, elevated platelet levels at primary therapy and the decrease of platelet count less than 25% after primary therapy were unfavorable prognostic factor for PFS(P = 0.022; P = 0.015) and OS(P = 0.013;P = 0.007) in recurrent EOC, but elevated plasma D-dimer and fibrinogen were not. In SKOV-3 ovarian cancer cell lines, suitable concentration platelet co-culture protected against apoptosis (P < 0.05).ConclusionsPlatelet count during treatment could be used as a biomarker used for monitoring the disease recurrence and predicting treatment response. And platelet with suitable concentration co-culture protected against apoptosis in SKOV3 cell line, which may explain clinical observations.

Pretreatment plasma fibrinogen level as a prognostic biomarker for patients with lung cancer

Many researchers have shown that pretreatment plasma fibrinogen levels are closely correlated with the prognosis of patients with lung cancer (LC). In this study, we thus performed a meta-analysis to systematically assess the prognostic value of pretreatment plasma fibrinogen levels in LC patients.A computerized systematic search in PubMed, EMBASE, Web of Science and China National Knowledge Infrastructure (CNKI) was performed up to March 15, 2018. Studies with available data on the prognostic value of plasma fibrinogen in LC patients were eligible for inclusion. The pooled hazard ratios (HRs) and odd ratios (ORs) with 95% confidence intervals (CIs) were used to evaluate the correlation between pretreatment plasma fibrinogen levels and prognosis as well as clinicopathological characteristics.A total of 17 studies with 6,460 LC patients were included in this meta-analysis. A higher pretreatment plasma fibrinogen level was significantly associated with worse overall survival (OS) (HR: 1.57; 95% CI: 1.39-1.77; p=0.001), disease-free survival (DFS) (HR: 1.53; 95% CI: 1.33-1.76; p=0.003), and progression-free survival (PFS) (HR: 3.14; 95% CI: 2.15-4.59; p<0.001). Furthermore, our subgroup and sensitivity analyses demonstrated that the pooled HR for OS was robust and reliable. In addition, we also found that a higher fibrinogen level predicted advanced TNM stage (III-IV) (OR=2.18, 95% CI: 1.79-2.66; p<0.001) and a higher incidence of lymph node metastasis (OR=1.74, 95% CI: 1.44-2.10; p=0.02).Our study suggested that higher pretreatment plasma fibrinogen levels predict worse prognoses in LC patients.

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.

Prognostic value of pretreatment plasma fibrinogen in patients with colorectal cancer: A systematic review and meta-analysis.

Background:Growing evidence showed that high pretreatment plasma fibrinogen could be used as a potential prognostic marker in colorectal cancer (CRC). However, the conclusions were controversial. Therefore, this meta-analysis was conducted to evaluate the prognostic value of pretreatment plasma fibrinogen in patients with CRC.Methods:Relevant studies were searched in the databases including PubMed, EMBASE, Web of Science, Cochrane library, and China National Knowledge Infrastructure up until December 10th, 2018. Pooled hazard ratios (HRs) with their 95% confidence intervals (CIs) were used to estimate the effects.Results:A total of 17 articles with 6863 patients were included in this meta-analysis. The results revealed that elevated pretreatment plasma fibrinogen was significantly associated with both poor overall survival (univariate analysis: HR = 1.69, 95% CI 1.47–1.95, P = .000; multivariate analysis: HR = 1.50, 95% CI 1.28–1.77, P = .000) and poor disease-free survival (univariate analysis: HR = 1.90, 95% CI 1.49–2.41, P = .000; multivariate analysis: HR = 2.08, 95% CI 1.52–2.86, P = .000) in patients with CRC.Conclusions:High pretreatment plasma fibrinogen level is significantly associated with worse survival outcomes in CRC patients. Plasma fibrinogen may be used as an effective prognostic marker and potential therapeutic target. Further studies are required to support these results.

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

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. 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. 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). 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.

Plasma fibrinogen as prognostic predictor in patients with metastatic renal cell carcinoma receiving target therapy

Background: The purpose of this work was to detect the influence of plasma fibrinogen level on the prognosis of patients with metastatic renal cell carcinoma (mRCC) before treatment of targeted therapy. Methods: We identified mRCC patients who received first-line therapy of sorafenib or sunitinib between January 2006 to December 2016 in Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine. Kaplan-Meier method was used to estimate the progression-free survival (PFS) and overall survival (OS); log-rank test was used to compare the survival outcomes between patients with low and high fibrinogen level; and cox proportional hazard regression model was used to estimate the prognostic value. Prognostic accuracy was determined using Harrell concordance index (C-index) and receiver operating curve (ROC) analysis. Results: Patients with high fibrinogen level both had significantly shorter median PFS (6 vs. 15 months, P<0.001) and OS (17 vs. 44 months, P<0.001) than those with low fibrinogen level. Multivariate analysis showed that pretreatment plasma fibrinogen was an independent predictor of PFS (HR 2.873, P<0.001) and OS (HR 3.213, P<0.001). The model built by the addition of fibrinogen improved predictive accuracy of PFS and OS compared with the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) model [Harrell C-index: 0.74 and 0.76, AUC (area under the ROC curve): 0.863, P<0.001]. Conclusions: High pretreatment plasma fibrinogen could be a significant risk factor for mRCC patients receiving target therapy and increase the prognostic accuracy of established prognostic model.

Prognostic significance of pretreatment plasma fibrinogen level in patients with digestive system tumors: a meta-analysis.

High pretreatment levels of plasma fibrinogen have been widely reported to be a potential predictor of prognosis in digestive system tumors; however, the conclusions are not consistent. Therefore, we performed a meta-analysis to comprehensively assess the prognostic roles of high pretreatment plasma fibrinogen levels in digestive system tumors. We searched for eligible studies in the PubMed, Embase, and Web of Science electronic databases for publications from the database inception to 1 September 2017. The endpoints of interest included overall survival, disease-free survival, and recurrence-free survival. We investigated the relationship between fibrinogenemia and overall survival in colorectal cancer (10 studies), gastric cancer (6), pancreatic cancer (6), hepatocellular carcinoma (7), and esophageal squamous cell carcinoma (10); the pooled results indicated that fibrinogenemia was significantly related to a worse overall survival (hazard ratio (HR) 1.73; 95% confidence interval (CI) 1.52, 1.97; P <0.001; HR 1.71; 95% CI 1.28, 2.28; P <0.001; HR 1.57; 95% CI 1.13, 2.17; P = 0.007; HR 1.89; 95% CI 1.57, 2.27; P <0.001, and HR 1.67; 95% CI 1.35, 2.07; P <0.001). Taken together, an increased pretreatment plasma fibrinogen level was related to worse survival in digestive system tumors, indicating that it could be a useful prognostic marker in these types of tumors.

Prognostic significance of pretreatment plasma fibrinogen in patients with hepatocellular and pancreatic carcinomas: A meta-analysis.

Background:The high pretreatment plasma fibrinogen has been widely reported to be a possible biomarker for predicting prognosis in hepatocellular carcinoma (HCC) and pancreatic carcinoma (PC), but persuasive conclusion has not been made yet. Thus, we herein conducted a meta-analysis to comprehensively assess the prognostic value of high pretreatment plasma fibrinogen in patients with HCC and PC.Method:We systematically searched PubMed, EMBASE, and Web of Science to identify eligible studies from inception to November 10, 2017.Results:Finally, a total of 12 publications with 13 studies were included. Of these eligible studies, 5 publications with 6 studies were about pancreatic cancer and 7 were about HCC. The pooled analysis indicated that high plasm fibrinogen level was significantly related to worse overall survival (OS) in HCC [hazard ratio (HR) = 1.87; 95% confidence interval (CI): 1.55–2.24; P < .01]. Similarly, from our result, it was found that high plasm fibrinogen was also significantly associated with worse OS in PC (HR = 1.56; 95% CI: 1.13–2.15; P < .01).Conclusion:Taken together, our meta-analysis confirmed that high plasma fibrinogen level could predict worse survival in HCC and PC.

Evaluation of cumulative prognostic score based on pretreatment plasma fibrinogen and serum albumin levels in patients with newly diagnosed high-grade gliomas.

This retrospective study was designed to determine the prognostic value of a cumulative score (FA score) based on pretreatment plasma fibrinogen and serum albumin levels for 326 patients newly diagnosed high-grade glioma (HGG). Receiver operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off values. Univariate and multivariate analysis were performed to evaluate the independent prognostic value of the FA scores associated with overall survival (OS) and progression-free survival (PFS). The optimal cut-off values were 2.815 g/L for fibrinogen and 43.65 g/L for albumin. PFS and OS were significantly worse for patients with higher FA scores. Patients with elevated fibrinogen level and decreased albumin levels had 3.00-fold higher risk of tumor progression and had a 3.23-fold higher risk of death compared with those with normal values. Multivariate analysis demonstrated FA score was an independent predictive factor for PFS and OS. Moreover, PFS and OS were better for the patients with lower FA score, either in patients with grade III or IV gliomas. These findings indicated that the pretreatment FA score could serve as a simple and noninvasive marker to predict the prognosis of patients with HGG.

Plasma Fibrinogen Correlates with Metastasis and is Associated with Prognosis in Human Nasopharyngeal Carcinoma.

Background: The purpose of this observational study was to evaluate the prognostic significance of the pre-treatment plasma fibrinogen level for survival outcomes in nasopharyngeal carcinoma (NPC).Methods: A total of 998 patients with NPC treated at a single centre in China were retrospectively enrolled, of whom 182 (18.2%) developed distant metastasis during follow-up. Survival analyses were performed by the Kaplan-Meier method and Cox regression modelling to measure 3-year overall survival (OS) and distant metastasis-free survival (DMFS).Results: Median OS for the entire cohort was 37.8 months. Using the cut-off value of 3.345 g/L identified in receiver operating curve analysis for fibrinogen, a high pre-treatment plasma fibrinogen level were associated with older age (P = 0.034), advanced TNM stage (P = 0.004) and development of distant metastasis (P < 0.001; Chi-square test). Multivariate Cox proportional hazard analysis demonstrated the pre-treatment plasma fibrinogen level was an independent significant prognostic factor for OS and DMFS in both the entire cohort and also among patients who developed distant metastasis during follow-up.Conclusions: This study suggests the pre-treatment plasma fibrinogen level may serve as an independent prognostic marker to predict the survival outcomes of patients with NPC, including patients with metastatic disease.

Prognostic Impact of Pretreatment Plasma Fibrinogen in Patients with Locally Advanced Oral and Oropharyngeal Cancer

BackgroundWe aimed to determine the prognostic significance of pretreatment plasma fibrinigen in patients with oral and oropharyngeal squamous cell carcinoma (OOSCC).MethodsA cohort of 183 patients with locally advanced OOSCC receiving preoperative chemoradiotherapy was retrospectively examined. Using ROC curve analysis, a pretreatment plasma fibrinogen cutoff value of 447mg/dL was determined. The primary endpoints were overall survival and recurrence-free survival. A secondary endpoint was to determine whether pretreatment plasma fibrinogen could predict treatment response to neoadjuvant chemoradiotherapy. Cox regression models and Kaplan–Meier curves were used for survival analyses.ResultsSeventy-one patients had an elevated pretreatment plasma fibrinogen (fibrinogen >447mg/dL). Patients with high fibrinogen showed significantly higher pathologic stages after neoadjuvant treatment than those with low fibrinogen (p = 0.037). In univariate analysis, elevated fibrinogen was associated with poor overall survival (p = 0.005) and recurrence-free survival (p = 0.008) Multivariate analysis revealed that elevated fibrinogen remained an independent risk factor for death (hazard ratio 1.78, 95% CI 1.09–2.90, p = 0.021) and relapse (hazard ratio 1.78, 95% CI 1.11–2.86, p = 0.016).ConclusionElevated pretreatment plasma fibrinogen is associated with lack of response to neoadjuvant chemoradiotherapy and reduced OS and RFS in patients with OOSCC. Thus, plasma fibrinogen may emerge as a novel prognostic indicator and a potential therapeutic target in OOSCC.

Elevated plasma fibrinogen level shows superior prognostic value than Epstein-Barr virus DNA load for stage IVA/B nasopharyngeal carcinoma patients in the intensity-modulated radiotherapy era

PurposeEffective prognostic factors for patients with stage IVA/B nasopharyngeal carcinoma (NPC) who are susceptible to distant metastases are limited. We aim to investigate the prognostic value of pretreatment plasma fibrinogen (FIB) level and Epstein–Barr virus DNA (EBV-DNA) load in these patients in the era of intensity-modulated radiotherapy (IMRT).ResultsThe 5-year DSS, DFS and DMFS rates of the entire cohort were 72.7%, 66.8%, 80.0%, respectively. High FIB level was identified as a negative prognostic factor for survival: the 5-year DSS, DFS and DMFS rates for patients with high FIB (> 4.0 g/L) and normal FIB (≤ 4.0 g/L) were 60.3% vs. 76.0%, 56.0% vs. 69.9%, and 59.4% vs. 85.5%, respectively (all P < 0.001). Subgroup analysis demonstrated that DSS, DFS and DMFS decreased as FIB gradually increased, even within the normal range. The risk of distant metastasis in patients with high FIB was over 3-fold than patients with normal FIB. EBV-DNA was not an independent prognostic factor for any survival outcomes in multivariate analysis.ConclusionHigh pretreatment FIB level shows superior prognostic value than EBV-DNA load for stage IVA/B NPC patients in the era of IMRT.Materials and MethodsA total of 755 patients with newly-diagnosed stage IVA/B NPC treated with definitive IMRT between January 2007 and December 2011 were enrolled. Plasma FIB and EBV-DNA were measured before treatment. Disease-specific survival (DSS), disease-free survival (DFS) and distant metastasis-free survival (DMFS) were calculated using the Kaplan-Meier method; differences were compared using the log-rank test.

High pretreatment plasma D-dimer levels are related to shorter overall survival in endometrial carcinoma

ObjectiveThe aim of the present study was to evaluate the prognostic value of pretreatment plasma dimerized plasmin fragment D (D-dimer) levels in endometrial carcinoma after adjusting for venous thromboembolism (VTE). Study designThe relationships between the following clinical parameters from 110 patients were investigated: age, histological type, the International Federation of Gynecology and Obstetrics (FIGO) stage, tumor grade, pretreatment plasma D-dimer level, platelet count, fibrinogen, CA19-9, and CEA levels, progression-free survival (PFS), and overall survival (OS). A survival analysis was performed using the Kaplan–Meier method, and prognostic factors were assessed using Cox's proportional hazards regression model. ResultsHigh pretreatment D-dimer levels were detected in 32% of cases. High D-dimer levels correlated with an advanced tumor stage, histological type, and tumor grade (P=0.001, P=0.021, P=0.044). A multivariate analysis identified high D-dimer levels as an independent prognostic factor for OS (P=0.013), whereas the histological type, but not D-dimer levels had independent prognostic value for PFS (P=0.225). ConclusionHigh pretreatment D-dimer levels have an impact on prognoses independently of VTE, and also have potential as markers to predict surgical outcomes in patients with endometrial carcinoma. Pretreatment D-dimer levels may contribute to the identification of high-risk populations for treatment decisions.
