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

ABSTRACT: 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.

Project description:BackgroundDysregulation of the long non-coding RNA small nucleolar RNA host gene 16 (lncRNA SNHG6) has been found in multiple cancers. However, a definite conclusion on the clinical value of lncRNA SNHG6 expression in human cancers has not been determined. The purpose of the present meta-analysis was to comprehensively elucidate the association between SNHG6 expression and clinical outcomes in cancers.MethodsA systematic search was performed through the PubMed, Web of Science, Chinese National Knowledge Infrastructure (CNKI), and Wangfang databases for relevant studies. The pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were collected to estimate the prognostic value, and the odds ratios (ORs) with 95% CIs were used to evaluate the relationship between lncRNA SNHG6 expression and clinicopathological features, including tumor invasion depth, lymph node metastasis (LNM), distance metastasis (DM), and TNM stage.ResultsIn total, 914 patients from 13 studies were included in this meta-analysis. The pooled results suggested that evaluated SNHG6 expression could predict an unfavorable overall survival (OS) (HR = 2.04, 95% CI:1.56-2.52) with no heterogeneity (I2 = 0.0%, p = 0.996). Subgroup analysis indicated a significant association between high SNHG6 expression and shorter OS in those studies with digestive system cancers (HR = 2.05, 95% CI: 1.47-2.62), or with sample size < 70 (HR = 2.70, 95% CI: 1.29-4.11), or with multivariate analysis (HR = 2.04, 95% CI: 1.44-2.64). Moreover, elevated SNHG6 expression was positively associated with tumor invasion depth (OR = 1.76, 95% CI: 1.18-2.63), LNM (OR = 1.60, 95% CI: 1.18-2.17), DM (OR = 1.90, 95% CI: 1.37-2.64) and advanced TNM stage (OR = 1.88, 95% CI: 1.36-2.60) in patients with cancers.ConclusionsHigh lncRNA SNHG6 expression was correlated with tumor invasion depth, LNM, DM, and advanced TNM stage, suggesting that SNHG6 may serve as a promising prognostic biomarker of human cancers.
