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.

Preoperative plasma fibrinogen and C-reactive protein/albumin ratio as prognostic biomarkers for pancreatic carcinoma.

Pancreatic carcinoma is characterised by high aggressiveness and a bleak prognosis; optimising related treatment decisions depends on the availability of reliable prognostic markers. This study was designed to compare various blood biomarkers, such as neutrophil/lymphocyte ratio (NLR), lymphocyte/monocyte ratio (LMR), platelet/lymphocyte ratio (PLR), C-reactive protein (CRP), albumin (Alb), plasma fibrinogen (PF), and CRP/Alb in patients with pancreatic carcinoma. Our study retrospectively reviewed 250 patients with pancreatic carcinoma diagnosed between July 2007 and December 2018. The Cutoff Finder application was used to calculate the optimal values of CRP/Alb and PF. The Chi-square test or Fisher's exact test was used to analyse the correlation of CRP/Alb and PF with other clinicopathological factors. Conducting univariate and multivariate analyses allowed further survival analysis of these prognostic factors. Multivariate analysis revealed that, in a cohort of 232 patients with pancreatic ductal adenocarcinoma (PDAC), the PF level exhibited statistical significance for overall survival (hazard ratio (HR) = 0.464; p = 0.023); however, this correlation was not found in the entire group of 250 patients with pancreatic carcinoma. Contrastingly, the CRP/Alb ratio was demonstrated statistical significance in both the entire pancreatic carcinoma cohort (HR = 0.471; p = 0.026) and the PDAC subgroup (HR = 0.484; p = 0.034). CRP/Alb and PF demonstrated a positive association (r=0.489, p<0.001) as indicated by Spearman's rank correlation analysis. Additionally, in 232 PDAC patients, the combination of the CRP/Alb ratio and PF had synergistic effects on prognosis when compared with either the CRP/Alb ratio or the PF concentration alone. PF concentration is a convenient, rapid, and noninvasive biomarker, and its combination with the CRP/Alb ratio could significantly enhance the accuracy of prognosis prediction in pancreatic carcinoma patients, especially those with the most common histological subtype of PDAC.

The prognostic value of preoperative plasma fibrinogen in Asian patients with urothelial cancer: a systematic review and meta-analysis.

We conducted this meta-analysis to comprehensively explore the prognostic value of the preoperative plasma fibrinogen in Asian patients diagnosed with urothelial cancer (UC). After a systematic search of Web of Science, PubMed, and Embase before May 2024, we included 10 studies in our meta-analysis. The hazard ratios (HRs) with 95% confidence interval (CI) for overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and progression free survival (PFS) were estimated using fixed effect model. This meta-analysis included a total of 2875 patients. UC patients with an elevated preoperative plasma fibrinogen had worse OS (pooled HR: 2.13, 95% CI: 1.81-2.51; P<0.001), CSS (pooled HR: 2.22, 95% CI: 1.83-2.70; P<0.001), RFS (pooled HR: 1.90, 95% CI: 1.59-2.27; P<0.001), and PFS (pooled HR: 2.12, 95% CI: 1.36-3.29, P=0.001). No significant heterogeneity or publication bias was found. Additionally, statistically significant pooled HRs were also calculated in subgroup analysis when stratified by cancer type, country, and cut-off value. The presence of elevated preoperative plasma fibrinogen levels is significantly correlated with unfavorable tumor outcomes in UCs.

Predictive Value of Preoperative Fibrinogen and Albumin Score (FA Score) for Prognosis and Chemotherapeutic Efficacy in Resected Colorectal Cancer: A Retrospective Cohort Study.

Background: Limited research elucidated the role of preoperative fibrinogen and albumin (FA) score in colorectal cancer (CRC). We aimed to clarify the predictive value of FA score for prognosis and chemotherapeutic efficacy in CRC patients who underwent curative resection. Materials and Methods: Patients' clinicopathological parameters of 735 cases of resected CRC were recruited retrospectively. Optimal cut-off values of the preoperative plasma fibrinogen (F) and albumin (A) were confirmed by receiver operating characteristic (ROC) curves. Patients were categorized into three groups based on the FA score, and were further divided into a chemotherapy group and a non-chemotherapy group. Correlations between FA score and clinicopathological features, as well as overall survival (OS), cancer-specific survival (CSS) and disease-free survival (DFS) were assessed with Kaplan-Meier (KM) survival method, univariate and multivariate Cox proportional hazard models, and subgroup analyses. Results: The Kaplan-Meier survival curves revealed that higher FA score could predict poorer OS and CSS (P<0.001). Multivariate analyses revealed that FA score was an independent prognostic factor for OS (P=0.037). In addition, subgroup analyses based on the histological feature and primary tumor location showed that elevated FA score was significantly associated with worse OS, CSS and DFS (all, P<0.05) in patients with non-mucinous colorectal adenocarcinoma and rectal cancer (RECC). Subgroup analyses based on the TNM stage showed that elevated FA score was significantly associated with worse OS, CSS (all, P<0.05) in patients with TNM stage II tumors. Furthermore, chemotherapy could benefit the OS and CSS in TNM stage III CRC patients with FA score 1 and 2 (all, P<0.05). Conclusion: The preoperative FA score is an independent prognostic factor for CRC patients who underwent curative resection and may help predict the responses to chemotherapy in clinical practice. FA score may serve as a complementary to the TNM staging system to identify high-risk patients.

Coagulation factor XIII is a critical driver of liver regeneration after partial hepatectomy

BackgroundActivation of coagulation and fibrin deposition in the regenerating liver appears to promote adequate liver regeneration in mice. In humans, perioperative hepatic fibrin deposition is reduced in patients who develop liver dysfunction after partial hepatectomy (PHx), but the mechanism underlying reduced fibrin deposition in these patients is unclear. Methods and ResultsHepatic deposition of cross-linked (ie, stabilized) fibrin was evident in livers of mice after two-thirds PHx. Interestingly, hepatic fibrin cross-linking was dramatically reduced in mice after 90% PHx, an experimental setting of failed liver regeneration, despite similar activation of coagulation after two-thirds or 90% PHx. Likewise, intraoperative activation of coagulation was not reduced in patients who developed liver dysfunction after PHx. Preoperative fibrinogen plasma concentration was not connected to liver dysfunction after PHx in patients. Rather, preoperative and postoperative plasma activity of the transglutaminase coagulation factor (F)XIII, which cross-links fibrin, was lower in patients who developed liver dysfunction than in those who did not. PHx-induced hepatic fibrin cross-linking and hepatic platelet accumulation were significantly reduced in mice lacking the catalytic subunit of FXIII (FXIII−/− mice) after two-thirds PHx. This was coupled with a reduction in both hepatocyte proliferation and liver–to–body weight ratio as well as an apparent reduction in survival after two-thirds PHx in FXIII−/− mice. ConclusionThe results indicate that FXIII is a critical driver of liver regeneration after PHx and suggest that perioperative plasma FXIII activity may predict posthepatectomy liver dysfunction. The results may inform strategies to stabilize proregenerative fibrin during liver resection.

Pre-operative Plasma Fibrinogen Level as a Potential Predictor of Pathological T3 Upstaging in Clinically Localized Renal Cell Carcinoma.

We investigated pre-operative factors for predicting pathological T3 (pT3) upstaging in clinical T1 renal cell carcinoma (RCC). We evaluated 181 patients with renal tumors suspected to be clinical T1 RCC. All patients had undergone a partial or radical nephrectomy. Pre-operative parameters, including patient characteristics, RENAL nephrometry score and blood tests were analyzed to determine factors predicting pT3 upstaging. Eight (4.4%) tumors were diagnosed as pT3. Large tumor diameter, less than 4 mm distance between the tumor and the renal collecting system and a high level of preoperative plasma fibrinogen were associated with pT3 stage. Multivariate analysis showed that a preoperative plasma fibrinogen level >330 mg/dl was a significant independent factor predicting upstage (p=0.041). Furthermore, among patients diagnosed with RCC (n=162), a preoperative plasma fibrinogen level >330 mg/dl was related to poor overall survival (p<0.001) and poor recurrence-free survival (p=0.002). A high preoperative plasma fibrinogen level may be a predictor of pT3 upstaging and may suggest the need for radical nephrectomy rather than partial nephrectomy because of the associated poor oncological outcomes.

Prognostic value of the combined preoperative plasma fibrinogen and systemic inflammatory indexes in ESCC patients

The prognostic indexes based on the combination of preoperative fibrinogen and systemic inflammatory indexes may have greater predictive value in esophageal squamous cell carcinoma (ESCC). It was found that the predictive ability of F-NLR was more valuable than other systemic inflammatory indexes. The preoperative F-NLR score was closely related to the TNM stage, and could be used as an important independent prognostic index for patients with ESCC. Then the nomogram model constructed by F-NLR and TNM stage had higher prognostic ability than that of AJCC stage for ESCC patients. Preoperative F-NLR is a new independent prognostic index and a potential marker for treatment response monitoring in patients with ESCC.

RCC, appeared as a cystic renal mass (CRM) on computed tomography (CT), should be differentiated from benign renal cysts. Due to the advancement of diagnostic imaging techniques and increased use of use of cross-sectional imaging, detection of small renal masses increased. Here, we demonstrated the genomic profiling of cystic T1a RCC in comparison with non-cystic T1a RCC and evaluated the usefulness of the biomarker for predicting the risk of malignancy in complex CRM of ≤4 cm. METHODS: Using a prospective cohort (ClinicalTrials.gov Identifier: NCT03694912) RCC database, 2 cases of cystic T1a RCC and 3 cases of non-cystic T1a RCC were selected, and RNA sequencing was performed. Plasma fibrinogen levels were retrospectively reviewed. Patients diagnosed as complex CRM of ≤4 cm that categorized as Bosniak categories IIF, III, and IV between 2019 to 2021 were included. The pathological results were compared with preoperative plasma fibrinogen levels. RESULTS: Totally, 520 genes were differentially expressed with fold changes and p-values <0.05, and 3 genes (fibrinogen alpha chain (FGA) gene, fibrinogen beta chain (FGB) gene, and fibrinogen gamma chain (FGG) gene) were identified with the greatest upregulation in cystic T1a RCC even after the adjustment. Plasma fibrinogen levels of cystic T1a RCC was 624.5 mg/dl, which was significantly higher than non-cystic T1a RCC with 363.0 mg/dl (P < 0.01) (Figure 1A). In validation group (58 patients), significantly higher plasma fibrinogen levels of cystic T1a RCC compared to non-cystic T1a ccRCC were confirmed (P < 0.05, Figure 1B). For complex CRM group, 29 patients were included and 22 patients underwent surgeries with malignancy rate as follows: Bosniak category IIF, 0/6 (0%); category III, 7/12 (58.3%); category IV, 4/4 (100%). Plasma fibrinogen level of those diagnosed as cystic RCC was 445.7 mg/dl, which was significantly higher than that of category IIF cysts and/or category III-IV cysts (P<0.01, Figure 1C and 1D). CONCLUSIONS: This study is the first to demonstrate and suggest the role of plasma fibrinogens to differentiate between benign complex CRM from cystic RCC of ≤4 cm.

Plasma Fibrinogen as a Predictor of Perioperative-Blood-Component Transfusion in Major-Nontraumatic-Orthopedic-Surgery Patients: A Cohort Study.

There is a trend towards increased perioperative bleeding in patients with plasma fibrinogen levels < 200 mg/dL-1. This study aimed to assess whether there is an association between preoperative fibrinogen levels and perioperative blood-product transfusion up to 48 h after major orthopedic surgery. This cohort study included 195 patients who underwent primary or revision hip arthroplasty for nontraumatic etiologies. Plasma fibrinogen, blood count, coagulation tests, and platelet count were measured preoperatively. A plasma fibrinogen level of 200 mg/dL-1 was the cutoff value used to predict blood transfusion. The mean (SD) plasma fibrinogen level was 325 (83) mg/dL-1. Only thirteen patients had levels < 200 mg/dL-1, and only one of them received a blood transfusion, with an absolute risk of 7.69% (1/13; 95%CI: 1.37-33.31%). Preoperative plasma fibrinogen levels were not associated with the need for blood transfusion (p = 0.745). The sensitivity and the positive predictive value of plasma fibrinogen < 200 mg/dL-1 as a predictor of blood transfusion were 4.17% (95%CI: 0.11-21.12%) and 7.69% (95%CI: 1.12-37.99%), respectively. Test accuracy was 82.05% (95%CI: 75.93-87.17%), but positive and negative likelihood ratios were poor. Therefore, preoperative plasma fibrinogen level in hip-arthroplasty patients was not associated with the need for blood-product transfusion.

Preoperative Risk Stratification of Increased MIB-1 Labeling Index in Pituitary Adenoma: A Newly Proposed Prognostic Scoring System.

The MIB-1 index is an important risk factor for progression-free survival (PFS) in pituitary adenoma (PA). Preoperatively, the MIB-1 index is not available in the decision-making process. A preoperative method regarding MIB-1 index estimation in PA has not been evaluated so far. Between 2011 and 2021, 109 patients with tumor morphology data, MIB-1 index data, and inflammatory and pituitary hormone laboratory values underwent surgery for PA. An MIB-1 index cutoff point (≥4/<4%) determines the probability of PFS in completely resected PA. An elevated MIB-1 index (≥4%) was present in 32 cases (29.4%) and was significantly associated with increased IGF-1, age ≤ 60, increased ACTH, and increased fibrinogen levels in the multivariable analysis. A scoring system (“FATE”) using preoperative IGF-1, age, ACTH, and plasma fibrinogen level enables the estimation of the MIB-1 index (sensitivity 72%, specificity 68%). The FATE score is also significantly associated with the time to PA progression after the complete resection of the PA. We propose the FATE score to preoperatively estimate the risk of an elevated MIB-1 index (≥4%), which might enable tailoring to medical decision-making, and follow-up interval scheduling, as well as inform future studies analyzing proliferative activities.

Impact of fibrinogen levels and modified Glasgow prognostic score on survival of stage III/N2 non-small cell lung cancer patients treated with neoadjuvant therapy and radical resection

PurposeThe prognostic value of pretreatment and preoperative fibrinogen plasma levels and the modified Glasgow prognostic score (mGPS) in stage III/N2 non-small cell lung cancer (NSCLC) patients who receive neoadjuvant treatment followed by radical surgery is yet unclear.MethodsFibrinogen levels and mGPS of 84 patients with initial stage III/N2 NSCLC, who received neoadjuvant therapy followed by complete surgical resection from 2002 to 2014 were retrospectively analyzed and correlated with clinical parameters and overall survival (OS). Data were analyzed using log-rank and Cox regression analysis adjusted for clinical and pathological factors.ResultsMedian serum fibrinogen level after neoadjuvant treatment was 439 mg/dL (IQR 158 mg/dL). Elevated fibrinogen levels (> 400 mg/dL) after neoadjuvant treatment were significantly associated with poorer OS (28.2 months vs. 60.9 months, HR 0.562, p = 0.048). Importantly, a decrease in fibrinogen levels after neoadjuvant treatment (n = 34) was found to be an independent predictor for favorable OS in multivariate analysis (HR 0.994, p = 0.025). Out of 80 patients, 55, 19 and 6 patients had a mGPS of 0, 1 and 2, respectively. Moreover, elevated mGPS after neoadjuvant treatment (mGPS 1–2) showed a non-significant trend for poorer OS compared to mGPS 0 (28.2 vs. 46.5 months, HR 0.587, p = 0.066).ConclusionElevated fibrinogen levels after neoadjuvant therapy prior to surgery in stage III/N2 NSCLC patients are associated with significant disadvantage for OS. A decrease in fibrinogen levels after neoadjuvant therapy was found to be a predictor for superior OS in this retrospective patient cohort.

EP05.02-007 Impact Of Fibrinogen Levels and mGPS on Survival of Stage III/N2 NSCLC Patients Treated with Neoadjuvant Therapy and Radical Surgery

The prognostic value of pretreatment and preoperative fibrinogen plasma levels and the modified Glasgow prognostic score (mGPS) in stage III/N2 non-small cell lung cancer (NSCLC) patients who receive neoadjuvant treatment followed by radical surgery is yet unclear.

Prognostic value of preoperative platelet-related parameters and plasma fibrinogen in patients with non-muscle invasive bladder cancer after transurethral resection of bladder tumor.

Aim: To investigate the prognostic value of preoperative mean platelet volume (MPV), MPV/lymphocyte ratio (MPVLR), MPV/platelet count ratio and plasma fibrinogen in patients with non-muscle invasive bladder cancer (NMIBC) after transurethral resection of bladder tumor (TURBT). Methods: A total of371 patients who underwent TURBT were enrolled. The main end points were disease-free survival (DFS) and overall survival (OS). Results: MPVLR, tumor size, tumor number and pathological grade were independent risk factors for postoperative DFS. Age and pathological grade were independent risk factors for postoperative OS. Conclusion: MPVLR is an independent risk factor for DFS in NMIBC patients andcould be used as a parameter to predict postoperative tumor recurrence in patients after TURBT.

The Screening of Fixation-Related Infection in Patients Undergoing Conversion Total Hip Arthroplasty after Failed Internal Fixation of Hip Fractures: A Single-Central Retrospective Study.

ObjectiveTo evaluate the diagnostic values of preoperative plasma fibrinogen and platelet count for screening fixation‐related infection (FRI) in patients undergoing conversion total hip arthroplasty (cTHA) after failed internal fixation of hip fractures.MethodThis was a single‐center retrospective study. Data were retrospectively analyzed for 435 patients who underwent cTHA in our hospital from January 2008 to September 2020. They were divided into infected (n = 30) and non‐infected groups (n = 405) according to the 2013 International Consensus Meeting (ICM) criteria. The diagnostic sensitivity and specificity of plasma fibrinogen and platelet count were determined using receiver operating characteristic (ROC) curves. Optimal predictive cutoffs of these two markers were determined based on the Youden index. In addition, the diagnostic value of preoperative serum C‐reactive protein (CRP) and erythrocyte sedimentation rate (ESR) for screening FRI were also evaluated based on the cutoffs recommended by the 2013 ICM Criteria. Finally, the diagnostic ability of various combinations of the plasma fibrinogen and platelet count as well as serum CRP and ESR was re‐assessed.ResultsThe numbers of patients with and without FRI were 30 (6.9%) and 405 (93.1%), respectively. Areas under the ROC curves were 0.770 for fibrinogen, 0.606 for platelet, 0.844 for CRP and 0.749 for ESR. The optimal predictive cutoff of fibrinogen was 3.73 g/L, which gave sensitivity of 60.0% and specificity of 90.5%. The optimal predictive cutoff for platelet was 241.5 × 109/L, which gave sensitivity of 46.7% and specificity of 83.7%. The CRP gave sensitivity of 66.7% and specificity of 92.5% with the predetermined cutoff of 10 mg/L, while the ESR gave sensitivity of 67.5% and specificity of 72.4% % with the predetermined cutoff of 30 mm/h. The combination of CRP and ESR showed high specificity of 93.2% but low sensitivity of 66.7%, while the corresponding values for CRP with fibrinogen were satisfied both for sensitivity of 80.0% and specificity of 78.7%. The combination of these four biomarkers gave sensitivity of 73.3% and specificity of 85.7%.ConclusionPreoperative serum CRP, ESR, plasma fibrinogen and platelet count have low sensitivity on their own for screening FRI in patients, but the combination of CRP with fibrinogen shows promise for that.

Prognostic value of preoperative plasma fibrinogen levels in resected stage I non-small cell lung cancer.

BackgroundThe number of surgical procedures has increased among patients with early‐stage lung cancer. If the poor prognostic factors for stage I non‐small cell lung cancer (NSCLC) can be simply validated preoperatively, appropriate treatment will be provided. The current study aimed to evaluate the prognostic value of preoperative plasma fibrinogen levels in patients with resected stage I NSCLC.MethodsWe retrospectively analyzed the clinicopathological information of patients (n = 149) who underwent lobectomy for stage I NSCLC between May 2014 and July 2016. Data about peripheral blood analysis, histopathological finding, and follow‐up assessment results were collected from the databases. Patients were divided into the low and high fibrinogen groups. Univariate and multivariate analyses were performed to evaluate the predictors of recurrence and survival.ResultsCompared with the low fibrinogen group (<377 mg/dl), the high fibrinogen group (≥377 mg/dl) had a significantly greater number of male participants (p = 0.04), smokers (p < 0.001), and those with elevated cytokeratin antigen levels (p = 0.04), lymphatic invasion (p = 0.007), and squamous cell carcinoma (p < 0.001). Plasma fibrinogen level was considered a significant independent factor for recurrence and overall survival on both the univariate and multivariate analyses (p < 0.001 and p = 0.010) and the multivariate analysis alone (p = 0.020 and p < 0.012).ConclusionPreoperative plasma fibrinogen level might be a useful predictor of recurrence and survival in patients with stage I NSCLC. The treatment strategy for patients with high fibrinogen levels could be cautiously considered preoperatively.

Association of Preoperative Plasma D-Dimer and Fibrinogen and Osteosarcoma Outcome.

ObjectiveWe aimed to evaluate the utility of preoperative D-dimer and plasma fibrinogen (PF) levels as useful markers for predicting the clinical value of patients with osteosarcoma.Methods145 enrolled patients with osteosarcoma were studied retrospectively. We determined the critical values of D-dimer and PF by receiver operating characteristic curve analysis. Cox regression analysis was used to assess prognostic role of the D-dimer and PF levels among osteosarcoma patients.ResultsThe critical values of D-dimer and PF were calculated to be 0.46 µg/mL and 3.34 mg/mL, respectively. Upregulation of D-dimer and PF showed positive correlations with a higher clinical stage, tumour metastasis and recurrence. Survival curve results confirmed that osteosarcoma patients with higher levels of D-dimer and PF predicted worse overall survival (OS) and progression-free survival (PFS). Moreover, only a high D-dimer level was associated with a shorter OS (P = 0.013) and PFS (P = 0.042) in both the univariate and multivariate analysis.ConclusionElevated preoperative D-dimer levels are correlated with aggressive clinicopathological features and poor survival outcomes, which indicates that assessment of the D-dimer could be a useful prognostic marker in osteosarcoma.

The Hidden Treasures of Preoperative Blood Assessment in Oral Cancer: A Potential Source of Biomarkers.

Simple SummaryIn this study, we assess the prognostic potential of immune and inflammatory elements determined preoperatively in the peripheral blood of patients with oral squamous cell carcinoma (OSCC). Preoperative plasma fibrinogen (Fib) and platelet-to-lymphocyte ratio (PLR) show strong correlations with patients’ outcomes. Analyzed together, in a new parameter named Fibrinogen-PLR Algorithm (FiPLA), predictive power increases significantly. Clinicians can use this new, easy, cost-effective, and globally available tool for risk stratification of patients with OSCC, as early as from the moment of diagnosis.(1) Background: Oral squamous cell carcinoma (OSCC) is a common malignancy, and the impact of immune and inflammatory mechanisms in its development and progression are of major interest. The aim of our study is to assess the prognostic potential of circulating immune and inflammatory elements determined preoperatively in patients with OSCC, as well as the development of a new compound parameter with predictive value. (2) Methods: We assessed preoperative fibrinogen (Fib) and the platelet-to-lymphocyte ratio (PLR) in 111 OSCC patients. Using a mathematic algorithm, we determined a composite parameter with cumulative information from Fib and PLR, named Fibrinogen-PLR Algorithm (FiPLA). Survival analysis, followed by bivariate and multivariate analyses, was subsequently conducted. (3) Results: Increased preoperative Fib and PLR levels were associated with poor outcome in OSCC (p = 0.0001 and p = 0.0015, respectively). Preoperative FiPLA values were also associated with poor patient survival (p < 0.0001). Multivariate analysis confirmed the independent prognostic role for FiPLA only (CI95% 1.232–67.770, p = 0.03), showing the superior predictive value of FiPLA compared to its individual components. (4) Conclusions: Preoperative assessments of circulating immune and inflammatory elements can provide high-quality prognostic information, and they represent valuable tools in clinical practice, facilitating the early risk stratification of patients with OSCC.

Prognostic value of preoperative inflammation-based predictors in patients with bladder carcinoma after radical cystectomy.

AimsEmerging evidence has related inflammation-based biomarkers to numerous carcinomas, including bladder carcinoma (BC). However, the role of inflammatory biomarkers in the prognosis of BC remains inconclusive. This study aimed to compare preoperative plasma fibrinogen (PF) and other inflammatory biomarkers such as the platelet–lymphocyte ratio (PLR), neutrophil–lymphocyte ratio (NLR), lymphocyte–monocyte ratio (LMR), C-reactive protein (CRP) level, and serum albumin level to predict the prognosis of patients with BC.MethodsThis article focused on a retrospective analysis of 175 patients with newly diagnosed BC who were admitted to our hospital from March 2005 to March 2016. Of these BC patients, 136 had undergone radical cystectomy (RC).ResultsAccording to multivariate analysis, high PF level was an independent predictor of overall survival (OS) in 136 BC patients receiving RC (HR = 3.759; P = 0.011), but not for all 175 BC patients. Combining the NLR and PF values showed higher predictive accuracy for OS than NLR or PF alone (P < 0.05). Additionally, for 136 BC patients who had undergone RC, a close relationship was found between high PF levels (≥3.39 g/L) and lymph node metastasis (P = 0.011) and clinical T stage (P = 0.015). Furthermore, PF was a superior prognostic factor compared with the LMR, PLR, CRP, and albumin values in 136 BC patients who had undergone RC (P < 0.001).ConclusionsThe preoperative PF level may be a prognostic biomarker; and when combined with the NLR, it can improve the predictive ability of the survival of BC patients, particularly of BC patients who underwent RC.

Preoperative Serum CA125 and Plasma Fibrinogen Levels as Predictors of Lymphovascular Space Invasion in Endometrial Cancer

Background: Lymphovascular space invasion has been shown to be a predictor of lymph node metastasisand decreased survival in patients with endometrial cancer. Unfortunately, LVSI status is most commonlynot available until after hysterectomy at the time of preparation of the final Pathology report. Therefore;LVSI status represent additional information to be considered in decision making process regarding whetherto perform lymphadenectomy or to deliver adjuvant therapy. Thus, it was important to find biomarkers topredict the risk of LVSI before surgery.Objective: To evaluate the value of serum CA125 and plasma fibrinogen for prediction of lymphovascularspace invasion in women with endometrial cancer.Study Design: A prospective observational cross-sectional study.Settings: was carried out in the Department of Obstetrics and Gynecology/ Baghdad Teaching Hospital, andNursing Home Hospital in Medical City complex, Baghdad, Iraq, over a period of 1 year starting from thefirst of December 2017 to the end of November 2018.Patients and Methods: Fifty-five women with endometrial cancer undergoing surgery were included inthis study. We compared the preoperative level of serum CA125 and plasma fibrinogen with postoperativehistopathological report regarding LVSI, the results were statistically analyzed.Results: (16.4%) of the patients with positive lympho-vascular invasion. CA-125, Fibrinogen, were highlysignificantly increased in patients with positive LVSI. Sensitivity was (88.9%), specificity (95.7%), negativepredictive value (95.0%), positive predictive value (91.0%),and accuracy of the test was (92.3%)whenthe cutoff value for CA125 was (28.75U/ml) while for plasma fibrinogen in cutoff value (317mg/dl)thesensitivity was (100.0%), specificity (95.7%),negative predictive value (100.0%), positive predictive value(95.9%) and the accuracy of the test was (97.8%)Conclusion: The preoperative assessment of serum CA 125 and plasma fibrinogen could be used to predictthe LVSI in endometrial cancer.
