Background. The prognostic value of loss of Krüppel-like factor 4 (KLF4) expression in digestive system cancers has not reached a consensus. This study aimed for a comprehensive investigation of the internal associations between KLF4 expression loss and prognostic implications in patients with digestive system cancers. Methods. We searched for all relevant literatures in the electronic databases until February 1, 2017. The degree of association between KLF4 and prognosis was evaluated by pooled hazard ratios (HRs) as well as relevant 95% confidence intervals (95% CIs). Results. Seventeen eligible studies with 2118 patients revealed that loss of KLF4 expression was connected with poor prognosis, with the pooled HRs of 1.61 (95% CI: 1.17–2.20, P=0.003) for the overall survival (OS) and 1.99 (95% CI: 1.12–3.52, P=0.001) for the disease-free survival (DFS)/recurrence-free survival (RFS)/metastasis-free survival (MFS). Additionally, loss of KLF4 expression was also related to a worse disease-special survival (DSS) yielding a pooled HR of 1.73 (95% CI: 1.08–2.77, P=0.022). Conclusion. Our findings suggest that loss of KLF4 expression is correlated with a bad outcome in most digestive system cancers, apart from esophagus squamous cell carcinoma (ESCC).

Objective. MicroRNA-182 (miR-182) exhibits altered expression in various cancers. The aim of this study was to investigate the predictive value of miR-182 expression for cancer patient survival.Methods. Eligible studies were identified through multiple search strategies, and the hazard ratios (HRs) for patient outcomes were extracted and estimated. A meta-analysis was performed to evaluate the prognostic value of miR-182.Results. In total, 14 studies were included. A high miR-182 expression level predicted a worse outcome with a pooled HR of 2.18 (95% CI: 1.53–3.11) in ten studies related to overall survival (OS), especially in Chinese populations. The results of seven studies evaluating disease-free survival/relapse-free survival/recurrence-free interval/disease-specific survival (DFS/RFS/RFI/DSS) produced a pooled HR of 1.77 (95% CI: 0.91–3.43), which was not statistically significant; however, the trend was positive. When disregarding the DSS from one study, the expression of miR-182 was significantly correlated with DFS/RFS/RFI (pooled HR = 2.52, 95% CI: 1.67–3.79).Conclusions. High miR-182 expression is associated with poor OS and DFS/RFS/RFI in some types of cancers, and miR-182 may be a useful prognostic biomarker for predicting cancer prognosis. However, given the current insufficient relevant data, further clinical studies are needed.

Abstract Background:Small nucleolar RNA host gene 3 (SNHG3) is a promising long non-coding RNA that may possess prognostic value for different types of tumors. The objective of this meta-analysis is to evaluate the prognostic value of lncRNA SNHG3 in cancer patients.Methods:A systematic literature search of the PubMed, Cochrane Library, EMBASE, Medline, Web of Science, CNKI, Weipu, and Wanfang electronic databases was carried out in this meta-anaysis. The synthetic hazard ratios (HRs) or odd ratios (ORs) with 95% confidence intervals (CIs) were obtained to determine the prognostic and clinicopathological significance of SNHG3 expression in tumors. Results:The final meta-anaysis included 17 studies that contained 2072 patients. The pooled results provided evidence that SNHG3 overexpression predicted reduced overall survival (OS) (HR=2.15, 95%CI: 1.76–2.63, P<0.00001), recurrence-free survival (RFS) ( HR=2.22, 95%CI: 1.04–4.76, P=0.04) and disease-free survival (DFS) (HR=2.04, 95%CI: 1.35–3.09, P=0.0007) for various cancers. Additionally, the SNHG3 overexpression was concerned with tumor node metastasis (TNM) stage (III/IV vs. I/II, OR=2.91, 95%CI: 1.60–5.29, P=0.0005), lymph node metastasis (LNM) (positive vs negative, OR=5.00,95%CI:2.82–8.87,P＜0.00001), distant metastasis (DM) (positive vs negative, OR=2.29, 95%CI: 1.52–3.47, P<0.0001) and tumor size (larger vs smaller, OR=1.80, 95%CI: 1.04–3.11, P=0.04).Conclusions:Our results indicated that SNHG3 overexpression was closely correlated with shorter OS in multiple cancer types, suggesting that SNHG3 might function as a promising predictor for clinical outcomes in cancer.

Abstract Background: M6A methylation modification of RNA can regulate the development of tumor cells. METTL3 is one of the modified methyltransferases. A growing number of studies have shown that high expression of METTL3 may be associated with the unfavorable prognosis in cancer patients and may become a new biomarker. Therefore, this meta-analysis was used to evaluate the prognostic value of METTL3 in cancer patients through the available literature information.Methods: Relevant studies were retrieved from electronic literature databases including six English databases and three Chinese databases. Correlation analysis was conducted by Stata SE 15.1 and RevMan 5.3 software. We analyzed 11 eligible studies with a total of 1638 cancer patients in this meta-analysis. We took advantage of HRs and ORs with 95% confidence intervals to evaluate the prognostic value of METTL3 in tumors. Besides,the article was qualified by MOOSE check lists and PRISMA Checklist. Results: The results of the meta-analysis indicated that high expression of METTL3 was associated with low overall survival (OS) (HR=2.67, 95%CI:2.19-3.25, P<0.00001) and disease-free survival (DFS) (HR=2.23, 95%CI:1.60-3.11, P<0.00001) in various cancers.Stratified analysis of cancer types showed that over expressed METTL3 was related to poor prognosis in digestive system cancer patients, including CRC(HR=2.29, 95%CI:1.50-3.49，P=0.0001) ,GC(HR=2.96，95%CI:2.13-4.12，P＜0.00001)，and liver cancer（HR=2.70，95%CI:1.88-3.88，P＜0.00001). Meanwhile, the elevated METTL3 expression also affected the lymph node metastasis (OR=3.40，95%CI=1.58-7.33，p=0.002) ，vascular invasion (OR=2.04，95%CI=1.06-3.95，p=0.03) and the tumors progression (III/IV vs. I/II: OR = 3.72, 95% CI: 1.94 - 7.13, P < 0.0001).Conclusion: The existing analysis indicates that METTL3 is associated with low OS and DFS in cancer patients and may serve as a biomarker to assess prognostic value.

Abstract Background In recent years, the Fibrinogen to pre-albumin ratio (FPR) has been reported in many studies to be significantly associated with the prognosis of various cancers. This systematic review and meta-analysis aimed to investigate the prognostic value of FPR in malignant tumors of the digestive system based on available evidence. Methods The relevant articles published before July 1, 2021, were systematically retrieved from electronic databases to evaluate the effect of Fibrinogen to pre-albumin ratio (FPR) on the prognosis of patients with malignant digestive system tumors and calculate the hazard ratio (HR) and the corresponding 95% confidence interval (CI). Result Thirteen articles, all from China, including 15 cohort studies and a total of 5116 cases, were included in this study. A high FPR was associated with poor overall survival (HR = 1.88, 95%CI 1.53–2.32, P < 0.001), recurrence-free survival (HR = 2.29, 95%CI 1.91–2.76, P < 0.001), progression-free survival (HR = 1.96, 95%CI: 1.33–2.90, P = 0.001), complications (HR = 1.78, 95%CI: 1.06–3.00, P = 0.029), disease-free survival (HR = 1.46, 95%CI: 1.08–1.97, P = 0.013) was significantly associated with cancer-specific survival (HR = 1.44, 95%CI: 1.15–1.79, P = 0.001). Even though intergroup differences were present, FPR was strongly associated with overall and relapse-free survival, and sensitivity analysis suggested that our results were stable. Conclusion FPR can be used as a valuable indicator to predict the prognosis of patients with malignant digestive system tumors.

Abstract Background: MicroRNA-135 (miR-135) is a well-known non-coding RNA that has been demonstrated to participate in tumorigenesis and cancer development; however, the clinical prognostic value of miR-135 in digestive system cancers remains controversial. This meta-analysis aims to explore the potential value of miR-135 as a prognostic marker for digestive system cancers. Methods: The PubMed, Embase, Cochrane Library, and Web of Science databases were searched for eligible articles published before 31 August 2019. Stata 12.0 software was used to analyze the overall survival (OS), disease-free survival (DFS), and recurrence-free survival (RFS) rates to access the prognostic value of miR-135 in digestive system cancers. We then used The Cancer Genome Atlas (TCGA) datasets to validate the meta-analysis results. Results A total of 1470 patients from 17 studies were included in this meta-analysis. The pooled results showed that enhanced miR-135 expression was significantly associated with poor OR (hazard ratio (HR): 1.790; 95% confidence interval (95% CI): 1.577–2.031; P=0.000), DFS (HR: 1.482; 95% CI: 0.914–2.403; P=0.110), and RFS (HR: 3.994; 95% CI: 1.363–11.697; P=0.012) in digestive system cancers. A sensitivity analysis confirmed the reliability of our findings, and no significant publication bias was observed. Conclusion: MiR-135 can be used as a novel biomarker for patients with digestive system cancers. We look forward to future large-scale clinical studies that will investigate the prognostic value of miR-135.

Purpose. The prognostic value of a new scoring system, termed F-NLR, that combines pretreatment fibrinogen level with neutrophil-lymphocyte ratio has been evaluated in various cancers. However, the results are controversial. The purpose of this study was to comprehensively analyze the prognostic value of F-NLR score in patients with cancers. Methods. An integrated search of relevant studies was conducted by screening the PubMed and Embase databases. Pooled hazard ratios, with 95% confidence intervals (CIs), for overall survival (OS) and disease-free survival (DFS)/progression-free survival (PFS) were calculated to estimate the prognostic significance of F-NLR score in patients with various tumors. A random effects model was used for comprehensive analysis, and subgroup and meta-regression analyses were used to explore sources of heterogeneity. Results. Thirteen articles reporting data from of 4747 patients were included in the study. Pooled analysis revealed that high F-NLR score was significantly associated with poor OS ( HR = 1.77 ; 95% CI, 1.51–2.08) and poor DFS/PFS ( HR = 1.63 ; 95% CI, 1.30–2.05). Subgroup and meta-regression analyses did not alter the prognostic role of F-NLR score in OS and DFS/PFS. Conclusions. Increased F-NLR score is significantly associated with poor prognosis in patients with cancers and can serve as an effective prognostic indicator.

Oral squamous cell carcinoma (OSCC) is a common type of cancer characterized by a low survival rate, mostly due to local recurrence and metastasis. In view of the importance of predicting tumor behavior in the choice of treatment strategies for OSCC, several studies have attempted to investigate the prognostic value of tissue biomarkers, including microRNA (miRNA). The purpose of this study was to perform a systematic review and meta-analysis to evaluate the relationship between miRNA expression and survival of OSCC patients. Studies were identified by searching on MEDLINE/PubMed, SCOPUS, Web of Science, and Google Scholar. Quality assessment of studies was performed with the Newcastle-Ottawa Scale. Data were collected from cohort studies comparing disease-free survival and overall survival in patients with high miRNA expression compared to those with low expression. A total of 15 studies featuring 1,200 OSCC samples, predominantly from Asia, met the inclusion criteria and were included in the meta-analysis. Poor prognosis correlated with upregulation of 9 miRNAs (miR-21, miR-455-5p, miiR-155-5p, miR-372, miR-373, miR-29b, miR-1246, miR-196a, and miR-181) and downregulation of 7 miRNAs (miR-204, miR-101, miR-32, miR-20a, miR-16, miR-17, and miR-125b). The pooled hazard ratio values (95% confidence interval) related to different miRNA expression for overall survival and disease-free survival were 2.65 (2.07–3.39) and 1.95 (1.28–2.98), respectively. The results of this meta-analysis revealed that the expression levels of specific miRNAs can robustly predict prognosis of OSCC patients.

AbstractObjective: A number of recent clinical studies have identified a relationship between elevated expressions of 14-3-3 and poorer patient prognosis in the context of several cancers. The present meta-analysis was therefore conducted to gain an enhanced understanding of the prognostic importance of 14-3-3 levels in cancer patients. Methods: Two reviewers independently systematically reviewed the Web of Science, Embase, and PubMed databases to identify published, suitable studies through October 2019. The correlation between the level of 14-3-3 and cancer patient survival were assessed based upon pooled HR (hazard ratios) and 95% CI (confidence intervals) derived from chosen studies. Results: In total we were able to identify 22 eligible studies that had enrolled 2676 patients in the present meta-analysis. Assessment of these studies revealed that elevated 14-3-3 level correlated significantly with poorer OS (overall survival) (HR : 1.93, 95% CI : 1.42-2.61) in cancer patients. This was true even when studies were analyzed in subgroups according to tumor type, sample size, analysis type, and method of HR determination. With respect to disease-free survival (DFS), the pooled HR for cancer patients expressing high levels of 14-3-3 was 1.89 (95% CI: 1.56-2.30). Patients with elevated 14-3-3 expression also exhibited reduced CSS (cancer-specific survival) (HR: 3.47, 95% CI: 2.12-5.69).Conclusions: The outcomes indicate that higher level of 14-3-3 correlates with poorer patient prognosis in a range of cancer types.Keywords: Meta-analysis, Prognosis, 14-3-3 Proteins C Continuous...

BackgroundSeveral recent publications have evaluated the prognostic value of preoperative hydronephrosis (HN) in patients with upper tract urinary carcinoma (UTUC). The aim of this meta-analysis was to explore the pooled effect of preoperative HN on the prognosis of UTUC patients treated with radical nephroureterectomy (RNU) based on current evidence.MethodsWe performed a systematic search of Pubmed, Cochrane library, and Web of Science databases from inception to June 2020. The outcomes of interest included overall survival (OS), cancer-special survival (CSS), disease-free survival (DFS), and intravesical recurrence-free survival (IVRFS).ResultsTwenty-two studies with a total of 7,542 patients satisfied the eligibility criteria and were finally included in this meta-analysis. The percent of patients with preoperative HN varied in the eligible studies, ranging from 18 to 81%. The pooled results showed that preoperative HN was significantly associated with worse OS (P = 0.004), CSS (P &lt; 0.001), and DFS (P = 0.005), but not IVRFS (P = 0.12). No obvious publication bias was detected by Begg’s test in all the analyses.ConclusionsThe results drawn in our meta-analysis suggest that the presence of preoperative HN is associated with worse prognosis in patients treated with RNU for UTUC. Therefore, closer surveillance and more aggressive therapy may be needed for UTUC patients present with preoperative HN. Well-designed prospective studies are necessary to substantiate the prognostic value of HN in UTUC.

BACKGROUND: Recent studies have shown that microRNAs (miRNA) have prognostic values in cancers. This meta-analysis seeks to summarize the global predicting role of miR-155 for survival in patients with a variety of carcinomas.METHODS: Eligible studies were identified through multiple search strategies. Data were extracted from studies investigating the relationship between miR-155 expression and survival in cancer patients. Combined hazard ratios (HRs) of miR-155 for outcome were analyzed.RESULTS: A total of 16 studies dealing with various carcinomas were included for this meta-analysis. For overall survival, higher miR-155 expression could significantly predict worse outcome with the pooled HR of 2.057 (95% CI: 1.392–3.039). For relapse or progress-free survival, elevated miR-155 was also a significant predictor, with a combined HR of 1.918 (95% CI: 1.311–2.806,). In addition, subgroup analysis showed that higher expression of miR-155 had the trends to predict worse outcome in lung cancer. However, the HRs did not reach the statistical significance.CONCLUSION: Our findings suggest that miR-155 detection has a prognostic value in cancer patients. Regularly measuring miR-155 expression may be useful in clinical practice.
