Prognostic significance of lncRNA DANCR expression in human cancers: a systematic review and meta-analysis

Several studies demonstrated that lncRNA differentiation antagonizing non-protein coding RNA (lncRNA DANCR) expression might have the potential capacity to predict the cancer prognosis; however, definite conclusion has not been obtained. The aim of this meta-analysis was to evaluate the prognostic value of lncRNA DANCR expression in cancers. PubMed, Web of Science, Scopus, and Embase were comprehensively searched for relevant studies. Studies meeting all inclusion standards were included into this meta-analysis. The analysis of overall survival (OS), disease-free survival (DFS), or clinicopathological features was conducted. Total 11 studies containing 1154 cancer patients were analyzed in this meta-analysis. The results showed, compared with low lncRNA DANCR expression, high lncRNA DANCR expression was significantly associated with shorter OS (hazard ratio [HR] = 1.85; 95% CI = 1.52–2.26; P<0.01) and DFS (HR = 1.82; 95% CI = 1.43–2.32; P<0.01) in cancers. Besides, high lncRNA DANCR expression predicted deeper tumor invasion (P<0.01), earlier lymph node metastasis (P<0.01), earlier distant metastasis (P<0.01), and more advanced clinical stage (P<0.01) compared with low lncRNA DANCR expression in cancer populations. High lncRNA DANCR expression was associated with worse prognosis compared with low lncRNA DANCR expression in cancers. LncRNA DANCR expression could serve as a prognostic factor of human cancers.     

Prognostic significance of X-linked inhibitor of apoptosis protein in solid tumors: A systematic review and meta-analysis

X-linked inhibitor of apoptosis protein (XIAP) is aberrantly expressed in solid tumors. Considering conflicting data, we conducted this meta-analysis to investigate its prognostic role. Electronic databases were searched to collect studies about associations between XIAP expressions and survival outcomes. Hazard ratio (HR), odds ratio (OR), and 95% confidence interval (CI) were utilized as effect size estimates. A total of 3,794 patients from 21 published studies were included. The results revealed that high XIAP expressions correlated with age (OR = 2.02; 95% CI, 1.07–3.84), lymph node metastasis (OR = 1.69; 95% CI, 1.02–2.77), histological grade (OR = 2.04; 95% CI, 1.01–4.11), and tumor stage (OR = 2.18; 95% CI, 1.20–3.96). The combined HR revealed that high XIAP expressions associated with poor overall survival (OS) (HR = 1.60; 95% CI, 1.22–2.10). Our study suggested high XIAP expressions may be indicative of poor prognosis in solid tumors.     

Prognostic role of c-Jun activation domain-binding protein-1 in cancer: A systematic review and meta-analysis

c-Jun activation domain-binding protein-1 (Jab1) is aberrantly overexpressed in multiple cancers and plays an oncogenic role in cancer progression. We examined the association between Jab1 expression and prognosis in patients with cancer by conducting a meta-analysis. A comprehensive search strategy was performed using the PubMed, Web of Science, Ovid and EMBASE in July 2020. Eligible studies were enrolled according to definite criteria. Twenty-seven studies involving 2609 patients were enrolled in this meta-analysis. A significant association between high Jab1 expression and poor overall survival (pooled hazard ratio [HR] 2.344, 95% confidence interval [CI]: 2.037-2.696) was observed. Subgroup analyses of the type of cancer, sample size, follow-up period, Jab1 detection method and preoperative treatment did not alter the significance. On pooling data from Cox multivariate analyses, high Jab1 expression was found to be an independent prognostic indicator for overall survival. In addition, high Jab1 expression was found to be associated with advanced clinicopathological features such as clinical stage, lymphatic metastasis, histological grade and distant metastasis in cancers. Our meta-analysis is the first to demonstrate that high Jab1 expression may be a promising indicator of poor prognosis and has an independent prognostic value for overall survival in patients with cancer.

Phosphorylation of focal adhesion kinase promotes extravasation of breast cancer cells

Inhibition of focal adhesion kinase (FAK) delays transendothelial migration of breast cancer cells. Here we investigate whether phosphorylation of specific tyrosine residues of FAK (397, 861, and 925) known to control aspects of cell migration on extracellular matrix (ECM), are also involved in transendothelial migration. AU-565 and MDA-MB-231 cells expressing Phe397 FAK show delayed or decreased transendothelial migration, demonstrating the involvement of the FAK autophosphorylation site. Only MDA-MB-231 cells expressing Phe861 FAK exhibit delayed transendothelial migration. Neither MDA-MB-231 nor AU-565 cells expressing Phe925 FAK show a change in transendothelial migration compared to untreated cancer cells. These findings suggest that modified signaling mechanisms regulate cancer cell migration through an endothelial monolayer versus those involved in cell migration on or through ECM.     

Prognostic role of EGR1 in breast cancer: a systematic review

EGR1 (early growth response 1) is dysregulated in many cancers and exhibits both tumor suppressor and promoter activities, making it an appealing target for cancer therapy. Here, we used a systematic multiomics analysis to review the expression of EGR1 and its role in regulating clinical outcomes in breast cancer (BC). EGR1 expression, its promoter methylation, and protein expression pattern were assessed using various publicly available tools. COSMIC-based somatic mutations and cBioPortal-based copy number alterations were analyzed, and the prognostic roles of EGR1 in BC were determined using Prognoscan and Kaplan-Meier Plotter. We also used bc-GenEx-Miner to investigate the EGR1 co-expression profile. EGR1 was more often downregulated in BC tissues than in normal breast tissue, and its knockdown was positively correlated with poor survival. Low EGR1 expression levels were also associated with increased risk of ER+, PR+, and HER2-BCs. High positive correlations were observed among EGR1, DUSP1, FOS, FOSB, CYR61, and JUN mRNA expression in BC tissue. This systematic review suggested that EGR1 expression may serve as a prognostic marker for BC patients and that clinicopathological parameters influence its prognostic utility. In addition to EGR1, DUSP1, FOS, FOSB, CYR61, and JUN can jointly be considered prognostic indicators for BC.     

Clinicopathological and prognostic significance of osteopontin expression in patients with prostate cancer: a systematic review and meta-analysis

Background: Evaluation of the feasibility for osteopontin (OPN) to serve as a biomarker in the prognosis and clinical-pathological features of prostate cancer (PCA) patients.Methods: The original publications related to OPN and PCA were comprehensively searched in the online databases, including PubMed, Embase, Cochrane Library, Web of Science, Medline, Wanfang and China National Knowledge Infrastructure up to August 2019. Results were analyzed by Revman 5.3 and Stata 12.0.Results: A total of 21 studies were included in the analysis and the result showed that the positive OPN expression group had a lower overall survival than the negative expression group (univariate: hazards ratio (HR) = 2.32, 95% confidence interval (95% CI) [1.74, 3.10], multivariate: HR = 2.41, 95% CI [1.63, 3.57]) and a lower biochemical relapse-free survival than the negative group (univariate: HR = 1.42, 95% CI [0.92, 2.17], multivariate: HR = 1.61, 95% CI [1.39, 1.87]). In addition, there was a higher expression level of OPN in PCA tissues than in normal prostate tissues (OR = 46.55, 95% CI [12.85, 168.59], P<0.00001) and benign prostatic hyperplasia (BPH) tissues (OR = 11.07, 95% CI [3.43, 35.75], P<0.0001). Moreover, OPN positive expression was also related to high Gleason score (OR = 2.64, 95% CI [1.49, 4.70], P=0.0009), high TNM stage (OR = 3.15, 95% CI [1.60, 6.20, P=0.0009), high Whitmore–Jewett stage (OR = 2.53, 95% CI [1.06, 6.03], P=0.04), high lymph node (OR = 3.69, 95% CI [1.88, 7.23], P=0.0001), and distant metastasis (OR = 8.10, 95% CI [2.94, 22.35], P=0.01). There was no difference observed in the differentiation of PCA (OR = 1.79, 95% CI [0.39, 8.33], P=0.46).Conclusion: OPN could be recognized as a promising diagnostic and prognostic biomarker for PCA patients.     

Prognostic value of miR-21 for prostate cancer: a systematic review and meta-analysis

Elevated levels of miR-21 expression are associated with many cancers, suggesting it may be a promising clinical biomarker. In prostate cancer (PCa), however, there is still no consensus about the usefulness of miR-21 as an indicator of disease progression. This systematic review and meta-analysis was conducted to investigate the value of miR-21 expression as a prognostic measurement in PCa patients. Medline (Ovid), EMBASE, Web of Science, Scopus and Cochrane Library databases were systematically searched for relevant publications between 2010 to 2021. Studies exploring the relationship between miR-21 expression, PCa prognosis and clinicopathological factors were selected for review. Those reporting hazard ratio (HR) and 95% confidence intervals (CIs) were subject to meta-analyses. Fixed-effect models were employed to calculated pooled HRs and 95% CIs. Risk of bias in each study was assessed using QUIPS tool. Certainty of evidence in each meta-analysis was assessed using GRADE guidelines. A total of 64 studies were included in the systematic review. Of these, 11 were eligible for inclusion in meta-analysis. Meta-analyses revealed that high miR-21 expression was associated with poor prognosis: HR = 1.58 (95% CI = 1.19–2.09) for biochemical recurrence, MODERATE certainty; HR = 1.46 (95% CI = 1.06–2.01) for death, VERY LOW certainty; and HR = 1.26 (95% CI = 0.70–2.27) for disease progression, VERY LOW certainty. Qualitative summary revealed elevated miR-21 expression was significantly positively associated with PCa stage, Gleason score and risk groups. This systematic review and meta-analysis suggests that elevated levels of miR-21 are associated with poor prognosis in PCa patients. miR-21 expression may therefore be a useful prognostic biomarker in this disease.     

Diagnostic and prognostic value of miR-200 family in breast cancer: A meta-analysis and systematic review

BackgroundBreast cancer (BC) is the most common cancer for women all over the world. Great interests have been paid to discover accurate and noninvasive methods for breast cancer diagnosis and prognosis. Although the diagnostic and prognostic value of microRNA-200 (miRNA- 200, miR-200) family has been revealed in many studies, the results were inconsistent. Thus, this meta-analysis aims to assess the overall value of miRNA-200 family in breast cancer diagnosis and prognosis.MethodRelevant studies were searched from the following databases: PubMed, PMC, EMBASE, and ScienceDirect using key words: ("miRNA-200 family" or "miR-141" or "miR-200a" or "miR-200b" or "miR-200c" or "miR-429") and (“HER2” or “Luminal A” or “Luminal B” or “TNBC”) and ("breast cancers" or "breast carcinoma" or "breast malignancy" or "breast tumor"). The sensitivity, specificity, AUC were then calculated to estimate the diagnostic accuracy of the miR-200 family. As for the prognostic value of the miR-200 family, the pooled hazard ratio (HR) was assessed. Heterogeneity among individual studies was also examined by subgroup analyses.ResultA total of 24 articles were included in the meta-analysis. The diagnostic value of miR-200s in BC was presented by the pooled sensitivity was 0.86 (95% CI: 0.83-0.88); the pooled specificity was 0.82 (95% CI: 0.72-0.89); the pooled AUC was 0.931 (95% CI: 0.919-0.942). Besides, expression of miR-200s in metastatic breast cancer has sensitivity, specificity and AUC of 0.70 (95%CI: 0.56-0.81), 0.72 (95%CI: 0.61-0.81), and 0.814 (95%CI: 0.741-0.903), respectively. The meta-analysis then revealed that high expression of miR-200 family corresponded to poor OS (HR: 1.63, 95% CI: 1.03-2.52), poor DFS (HR: 1.55, 95% CI: 0.95-2.56) in BC patients while downregulation of miRNA-200s corresponded to poor OS (HR= 0.84, 95%CI: 0.46-1.63) in TNBC patients and poor OS (HR=0.49; 95%CI: 0.27-0.88) in luminal BC patient.ConclusionThe MiR-200 family has high diagnostic accuracy and can be used as an important biomarker to prognosticate breast cancer.     

Association between comorbidity and participation in breast and cervical cancer screening: A systematic review and meta-analysis

BackgroundComorbidity is associated with poor outcomes for cancer patients but it is less clear how it influences cancer prevention and early detection. This review synthesizes evidence from studies that have quantified the association between comorbidity and participation in breast and cervical screening.MethodsPubMed, CINAHL and EMBASE databases were systematically searched using key terms related to cancer screening and comorbidity for original research articles published between 1 January 1991 and 21 March 2016. Two reviewers independently screened 1283 studies that met eligibility criteria related to Population (adult, non-cancer populations), Exposure (comorbidity), Comparison (a ‘no comorbidity’ group), and Outcome (participation in breast cancer or cervical screening). Data was extracted and risk of bias assessed using a standardised tool from the 22 studies identified for inclusion (17 breast; 13 cervical). Meta-analyses were performed for participation in breast and cervical screening, stratified by important study characteristics.ResultsThe majority of studies were conducted in the United States. Results of individual studies were variable. Most had medium to high risk of bias. Based on the three “low risk of bias” studies, mammography screening was less common among those with comorbidity (pooled Odds Ratio 0.66, 95%CI 0.44–0.88). The one “low risk of bias” study of cervical screening reported a negative association between comorbidity and participation.ConclusionWhile a definitive conclusion could not be drawn, the results from high quality studies suggest that women with comorbidity are less likely to participate in breast, and possibly cervical, cancer screening.     

Parity and risk of developing breast cancer according to tumor subtype: A systematic review and meta-analysis

BackgroundClinical breast cancer subtypes are categorized basing on the expression of hormone receptors and overexpression of the human epidermal growth factor receptor 2 (HER2). It is still unclear whether parity impact the risk of different breast cancer subtypes.MethodsWe searched eight mainstream databases for published epidemiologic studies that assessed the relationship between parity and risk of breast cancer subtypes up to January 12, 2021. Parity number were unified into nulliparity and ever parity. The random-effects or fixed-effect models were used to calculate the pooled odds ratios (ORs) and 95% confidence intervals (CIs) among different subtypes. Restricted cubic spline analysis with four knots was applied to determine the relationship of parity number and risk of breast cancer subtypes.ResultsWe pooled sixteen case-control and four cohort studies, and performed an analysis including 7795 luminal A, 3576 luminal B, 1794 HER2-overexpressing, and 5192 triple-negative breast cancer cases among 1135131 participants. The combined ORs for ever parity versus nulliparity indicated a 34% reduction in luminal A risk (OR=0.66, 95% CI: 0.56–0.78), and a 29% reduction in luminal B risk (OR=0.71, 95% CI: 0.63–0.81), there was no significant association in HER2-overexpressing or TNBC risk. In the dose-response analysis, we observed a potentially non-linear and gradually increasing protective relationship between the number of parity and luminal breast cancer risk.ConclusionsThe effect of parity on breast cancer seems to vary among breast tumor subtypes, and it plays a protective role in luminal breast cancer.     

Prognostic value of periostin in multiple solid cancers: A systematic review with meta-analysis

Previous studies have shown that the expression of periostin (POSTN) is significantly correlated with prognosis in multiple solid cancers. However, the function of POSTN in tumorigenesis and its relationship with clinical outcomes have not been systematically summarized and analyzed. Thus, a meta-analysis was performed to evaluate the prognostic pertinence of POSTN in solid cancer. We conducted a systematic search in the PubMed, EMBASE, Web of Science, and Cochrane library databases, and a total of 10 studies were used to assess the association of POSTN expression and patients’ overall survival (OS) and disease-free survival (DFS). The hazard ratio (HR) or odds ratio (OR) and their corresponding 95% confidence intervals (95% CIs) were further calculated to estimate the association between POSTN and relevant clinical parameters of solid cancer patients. The pooled results indicated that POSTN overexpression was associated with poor OS (HR = 2.35, 95% CI = 1.88–2.93, p < .00001) and DFS (HR = 2.70, 95% CI = 2.00–3.65, p < .00001) in a cohort of 993 patients with cancer. Subsequent analyses showed that the positive expression ratio of POSTN was evidently higher in cancer tissues than in normal tissues (OR = 7.44, 95% CI = 3.66–13.95, p < .00001). In addition, subgroup analysis showed that POSTN was related to microvascular invasion (OR = 5.09, 95% CI = 3.07–8.44, p < .00001), tumor differentiation (OR = 2.03, 95% CI = 1.41–2.91, p = .0001), and lymph node metastasis (OR = 3.05, 95% CI = 2.01–4.64, p < .00001). These data showed that POSTN could be a credible prognostic biomarker and a potential therapeutic target in human solid cancer.     

Role of c-Src and focal adhesion kinase in progression and metastasis of estrogen receptor-positive breast cancer

The non-receptor tyrosine kinases c-Src and focal adhesion kinase (Fak) mediate signal transduction pathways that regulate cell proliferation, survival, invasion, and metastasis. Here, we investigated whether c-Src and Fak are activated during progression of hormone-dependent breast cancer. Maximally active c-Src was overexpressed in a subset of tamoxifen-resistant variants and in metastases of recurrent hormone-treated breast cancer. Active Fak was also frequently observed in these tumors. We also show that estrogen receptor (ER) can bind to Fak and that estrogen can modulate Fak autophosphorylation supporting a cross-talk between these two pathways. Inhibition of c-Src activity blocked proliferation of all tamoxifen-resistant variants, suggesting that inhibitors of c-Src-Fak activity may delay or prevent progression and metastasis of ER-positive tumors. These studies also raise the possibility that fully active forms of c-Src and Fak in breast tumors may be biomarkers to predict tamoxifen resistance and/or risk of recurrence in ER-positive breast cancer.     

Prognostic significance of vascular endothelial growth factor immunohistochemical expression in gastric cancer: a meta-analysis

Vascular endothelial growth factor (VEGF) is considered as a prime mediator of angiogenesis, and has been implicated in carcinogenesis and metastasis. Various studies examined the relationship between VEGF protein overexpression with the clinical outcome in patients with gastric cancer, but yielded conflicting results. The prognostic significance of VEGF overexpression in gastric cancer remains controversial. Electronic databases updated to July 2011 were searched to find relevant studies. A meta-analysis was conducted with eligible studies which quantitatively evaluated the relationship between VEGF overexpression and survival of patients with gastric cancer. Survival data were aggregated and quantitatively analyzed. We performed a meta-analysis of 30 studies (n?=?3,999 patients) that evaluated the correlation between VEGF overexpression detected by immunohistochemistry and survival in patients with gastric cancer. Combined hazard ratios suggested that VEGF-A overexpression had an unfavorable impact on overall survival (OS) (HR [hazard ratio]?=?1.49, 95?% CI [confidence interval]: 1.22-1.77) and disease free survival (DFS) (HR?=?1.85, 95?% CI: 1.38-2.32) in patients with gastric cancer. However, VEGF-C overexpression did not significantly correlate with OS (HR?=?1.24, 95?% CI: 0.92-1.56) or DFS (HR?=?1.15, 95?% CI: 0.78-1.52). VEGF-D is an unfavorable indicator of OS (HR?=?1.68, 95?% CI: 1.02-2.34) and DFS (HR?=?1.88, 95?% CI: 1.07-2.70) in patients with gastric cancer. VEGF-A and VEGF-D overexpression indicated a poor prognosis for patients with gastric cancer. VEGF-C overexpression was not associated with poor prognosis in patients with gastric cancer. The prognostic value of VEGF on survival still needs further larger prospective trials to be confirmed.     

Effect of pomegranate juice on vascular adhesion factors: A systematic review and meta-analysis

BackgroundCardiovascular diseases, obesity, and insulin resistance demonstrate elements of functional impairment of the endothelium. Treatment of endothelial dysfunction with natural products, such as pomegranate, can open new ways in the treatment of cardiovascular diseases.PurposeThe present meta-analysis provides information in highlighting the role of pomegranate in endothelial dysfunction.MethodsVarious databases, such as PubMed, Scopus, Web of Science, Cochrane, and Google Scholar, were searched up to July 2020 using relevant keywords. We have selected the studies that investigated the effects of pomegranate on vascular adhesion factors, including intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), E-selectin, and interleukin-6 (IL-6). MD with 95% CrI with 100,000 iterations by using Markov chain Monte Carlo code were used.ResultsPooled effect size of articles in human studies indicated that pomegranate juice was not significantly effective on ICAM-1 [MD: −0.42; CrI: (−1.01, 0.17)], VCAM-1 [MD: −0.20; CrI: (−1.95, 1.40)], and E-selectin [MD: −0.21; CrI: (−1.62, 1.21)] compared to the control group. But it can significantly reduce IL-6 [MD: −1.07; CrI: (−1.90, -0.19)].ConclusionGenerally, present study showed that pomegranate juice has no significant effect on vascular adhesion factors, ICAM-1, VCAM-1, and E-selectin, but can reduce IL-6 significantly. Future prospective randomized clinical trials with longer intervention duration are warranted to obtain a precise conclusion.     

Socioeconomic differences in prostate cancer treatment: A systematic review and meta-analysis

BackgroundSince the 1990s, most nations have had a reduction or stabilisation in prostate cancer mortality. However, socioeconomic differences in disease specific mortality and survival have persisted. This has been partially attributed to differences in treatment choices. The aim of this systematic review and meta-analysis was to describe and quantify socioeconomic differences in use of prostate cancer treatment in the literature.MethodsMEDLINE, CINAHL and Embase were searched from 01 January 2000–01 April 2021 to identify articles that reported use of prostate cancer treatment by socioeconomic status. Random effects meta-analysis was used to analyse socioeconomic differences in treatment where there was more than one study for treatment type. A modified version of the Newcastle-Ottawa Scale was used to assess risk of bias.ResultsOut of 7267 articles identified, eight met the inclusion criteria and six were analysed using meta-analysis. Meta-analysis could only be completed for non-active treatment (watchful waiting/active surveillance). Lower education was associated with non-active treatment (OR=0.90, [95% CI 0.83–0.98], p=0.02, I²=67%), however, level of income was not (OR=0.87, [CI 0.75–1.02], p=0.08, I²=94%). Sensitivity analysis of studies where active surveillance was the outcome (n=3), indicated no associations with level of income (OR=0.91, [95% CI 0.82–1.01], p=0.08, I²=52%) or education (OR=0.88, [95% CI 0.70–1.10], p=0.25, I²=79%). All studies were assessed as high-risk of bias.DiscussionThe relationship between socioeconomic status and prostate cancer treatment depended on the socioeconomic variable being used, the treatment type and how it was defined in research. Considerable methodological limitations were identified. Further research should improve on previous findings and address current gaps.     

Ethiopian women's breast cancer self-examination practices and associated factors. A systematic review and meta-analysis

BackgroundBreast neoplasm is the most frequently diagnosed and the leading cause of cancer death in the vast majority of the countries. Breast cancer self-examination is a check-up of a woman does at home to look for changes or problems in the breast tissue. The benefit of early recognition is for early treatment that is more effective, higher long-term survival rates and better quality of life. The aim of this review was to determine the pooled prevalence of breast cancer self-examination practice and identify its associated factors among Ethiopian women.MethodsGoogle Scholar, PubMed, Science Direct, web of science, and Cochrane Library were used for search of articles. This review includes thirty four articles conducted in Ethiopia between 2011 and 2020. The review contains 14,908 women to determine the ever pooled prevalence of breast cancer self-examination practice. Health workers and students made up 28.35% of the total participants. Data were extracted using a standardized data extraction format prepared in Microsoft Excel and analyzed with Stata 14. To assess heterogeneity I² test were used. A random effect meta-analysis model was used to estimate the pooled breast cancer self-examination (BCSE) practice of Ethiopian women. Moreover associated factors were also assessed.ResultsIn Ethiopian women, the overall ever and regular pooled breast cancer self-examination practice was 36% (95% CI: 28, 43) and 16% (95% CI: 28, 43) respectively. The ever pooled prevalence for health workers or students was 53% (95% CI: 41, 65), whereas for other participants it was 25% (95% CI: 19, 30). Good knowledge about breast self-examination (AOR: 3.69: 95% CI: 2.70, 5.05), positive attitude towards BCSE (AOR: 2.72: 95% CI: 1.74, 4.24), Getting to know people with breast cancer(AOR: 2.77: 95% CI: 1.51, 5.09), family history of breast cancer (AOR: 2.49: 95% CI: 1.60, 3.88) and personal history of breast cancer (AOR: 2.26: 95% CI: 1.70, 3.01) were associated factors to BCSE practice among Ethiopian women. All of the studies included in this review were conducted in a cross-sectional design was a limitation of this review and meta-analysis.ConclusionThis review and meta-analysis showed the ever and regular pooled prevalence of BCSE among Ethiopian women. More than one third of Ethiopian women ever practiced BCSE. We recommend that awareness creation should be perform in order to tackle the risk of breast cancer.
