Background. T cell immunoglobulin and ITIM domain (TIGIT) is a recently identified immunosuppressive receptor. The expression levels of TIGIT affect the prognosis of patients with solid tumors. To fully comprehend the role of TIGIT on the prognosis of patients with solid tumors, we conducted a meta-analysis. Methods. We performed an online search of PubMed, Embase, Web of Science (WOS), and MEDLINE databases for literature published till March 31, 2021. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the literature, and Stata 16.0 and Engauge Digitizer 4.1 software were used for data analysis. Results. Our literature search identified eight papers comprising 1426 patients with solid tumors. Increased expression of TIGIT was associated with poor prognosis. High expression of TIGIT was a risk factor for overall survival (OS) { hazard   ratio   HR = 1.66 , 95% confidence interval (CI) [1.26, 2.20], P < 0.001 } and progression-free survival (PFS) ( HR = 1.44 , 95% CI [1.15, 1.81], P = 0.01 ). We performed subgroup analysis to explore the source of heterogeneity, colorectal cancer ( HR = 2.07 , 95% CI [0.23, 18.82], P = 0.518 ), lung cancer ( HR = 1.29 , 95% CI [0.96, 1.72], P = 0.094 ), esophageal cancer ( HR = 1.70 , 95% CI [1.20, 2.40], P = 0.003 ), and other cancers ( HR = 1.83 , 95% CI [1.25, 2.68], P = 0.002 ). In addition to cancer type, expression location, sample size, and different statistical analysis methods are also considered the possible causes of heterogeneity between studies. Funnel plots suggested no publication bias for OS ( P = 0.902 ), and Egger’s test supported this conclusion ( P = 0.537 ). Conclusion. TIGIT expression was associated with OS and PFS in patients with solid tumors. Patients with elevated TIGIT expression have a shorter OS and PFS, and TIGIT expression could be a novel biomarker for prognosis prediction and a valuable therapeutic target for solid tumors.

Abstract Background To evaluate the prognostic value of pretreatment lymphocyte counts with respect to clinical outcomes in patients with solid tumors. Methods Systematic literature search of electronic databases (Pubmed, Embase and Web of Science) up to May 1, 2018 was carried out by two independent reviewers. We included Eligible studies assessed the prognostic impact of pretreatment lymphocytes and had reported hazard ratios (HR) with 95% confidence intervals (CIs) for endpoints including overall survival (OS) and progression-free survival (PFS). Only English publications were included. Results A total of 42 studies comprising 13,272 patients were included in this systematic review and meta-analysis. Low pretreatment lymphocyte count was associated with poor OS (HR = 1.27, 95% CI 1.16–1.39, P < 0.001, I2 = 58.5%) and PFS (HR = 1.27, 95% CI 1.15–1.40, P < 0.001, I2 = 25.7%). Subgroup analysis disaggregated by cancer type indicated that low pretreatment lymphocytes were most closely associated with poor OS in colorectal cancer followed by breast cancer and renal cancer. Conclusions Low pretreatment lymphocyte count may represent an unfavorable prognostic factor for clinical outcomes in patients with solid tumors.

Background and objectivesStudies have shown that serum ferritin (SF) has unfavourable prognostic value in hepatobiliary and pancreas (HBP) cancers. This meta-analysis aimed to comprehensively assess the prognostic role of pretreatment SF in patients with HBP cancers.MethodsEligible studies published before January 2020 were obtained through a comprehensive search in the PubMed, Web of Science, Cochrane Library and EMBASE databases. Pooled HRs and 95% CIs were then employed as effect sizes.ResultsSeven studies comprising 1244 patients were pooled. Elevated pretreatment SF was associated with worse overall survival (OS) (HR 1.60, 95% CI 1.36 to 1.88, p<0.001) and recurrence-free survival/progression-free survival/time to recurrence (HR 1.70, 95% CI 1.15 to 2.52, p=0.008). Significant prognostic value of elevated pretreatment SF on OS was detected in the subgroups regardless of the cancer type, race, SF cut-off value, tumour-node-metastasis stage and Newcastle-Ottawa Scale score.ConclusionElevated pretreatment SF was associated with worse survival outcome of patients with HBP cancers. As such, it may serve as a novel prognostic biomarker for HBP cancers.

Background/Aims: Several recent studies have demonstrated that Stathmin 1expression may be closely associated with prognosis in patients with various types of cancers. In the present study, we conducted a meta-analysis of all available studies in the English literature to assess the prognostic value of Stathmin 1expression in patients with solid cancers. Methods: The online databases PubMed, Embase, and Web of Science were searched for literature regarding Stathmin 1 and its association with patient outcomes associated with solid cancers. Results: A total of 23 articles including 26 studies that contained 5 335 patients were retrieved and analyzed. Our results indicated that high Stathmin 1 expression yielded a worse overall survival (OS) (hazard ratio [HR] = 2.17, 95% confidence interval [CI]: 1.81–2.60), disease-free survival (DFS) (HR = 2.46, 95% CI: 2.00–3.02), disease-specific survival (DSS) (HR = 1.98, 95% CI: 1.58– 2.47) and progression-free survival (PFS)/recurrence-free survival (RFS) (HR = 2.09, 95% CI: 1.51–2.89). Furthermore, the association of high Stathmin 1 expression with poor survival was significant even for sub-group analyses of different tumor types, ethnicities, methods used to calculate HRs, detected methods, and analysis types. Conclusion: In summary, this meta-analysis determined that high Stathmin 1 expression is associated with poor prognosis in patients with solid cancers and expression of this protein could be a clinically useful prognostic biomarker.

The use of tyrosine kinase inhibitors (TKIs) in the treatment of solid tumors is the expected standard of care for many types of tumors. Since the description of signal transduction pathways, followed by the development of small molecules designed to inhibit those pathways, there has been significant improvement not only in progression-free survival and overall survival but also in aiming toward chemotherapy-free treatment of solid tumors to maximize quality of life. This article reviews available TKIs and discusses toxicity, dosing, and resistance.

Background The prognostic significance of the expression of the miR-221/222 family in cancer remains controversial. We here performed a meta-analysis of published data investigating the effects of miR-221/222 expression on both overall survival (OS) and disease-free survival (DFS) among patients with cancer. Methods A systematic search of the PubMed, Embase, Cochrane, and CNKI databases was performed with the last search being updated on March 15, 2013. The hazard ratio (HR) and its 95% confidence interval (95% CI) were used to assess the strength of association. Results A total of 17 studies involving 1,204 subjects were included in this meta-analysis. When assessing the prognostic significance of miR-221 expression, the pooled HR was 1.91 (95% CI: 1.28-2.85, p=0.002) for OS and 1.36 (95% CI: 0.88-2.09, p=0.163) for DFS. When assessing the prognostic significance of miR-222 expression, the pooled HR was 2.15 (95% CI: 1.51-3.06, p<0.0001) for OS and 1.37 (95% CI: 0.45-4.13, p=0.581) for DFS. We also found that an elevated miR-221 expression was significantly associated with poor OS when stratifying by ethnicity, cancer type, statistical methodology, sample, and quality assessment. There was no evidence of publication bias. Conclusion The meta-analysis demonstrates that the elevated expression of miR-221 and miR-222 is associated with poor OS in patients with cancer. The miR-221/222 cluster might be used as a potential therapeutic strategy in clinical practice. More work is required to fully elucidate the role of the miR-221/222 family in human tumors.

Purpose: Sarcopenia is a major disease affecting mortality and quality of life in the elderly population. We performed a meta-analysis of studies on the community-dwelling population to investigate the prevalence of sarcopenia and its association with diabetes.Methods: Databases were searched for studies published up to February 3, 2021, reporting the prevalence of sarcopenia in patients with and without diabetes. Data extraction and quality assessment were performed according to the Newcastle-Ottawa scale.Results: Six articles were included in the systematic review. All the patients were Asian, aged ≥60 years (women 53.4%), and the diabetic and non-diabetic population was 1,537 and 5,485, respectively. In all six studies, the Asian Working Group for Sarcopenia criteria were used to diagnose sarcopenia. The prevalence of sarcopenia was 15.9% in diabetics and 10.8% in non-diabetics. Diabetics showed a significantly higher risk of sarcopenia than non-diabetics (pooled OR = 1.518, 95% CI = 1.110 to 2.076, Z-value = 2.611, p = 0.009).Conclusion: Among the Asian community-dwelling geriatric population, the prevalence of sarcopenia was significantly higher in diabetics than in non-diabetics. These results suggest that strategies for the management of sarcopenia are required in Asian elderly patients, especially with diabetes.

AbstractBackgroundThis systematic review and meta-analysis was aimed to evaluate the efficacy and safety of tocilizumab (TCZ) in treating severe coronavirus disease 2019 (COVID-19).MethodsThe electronic search was performed using PubMed, Scopus, CENTRAL, and Google scholar to identify the retrospective observational reports. The studies published from 01 January 2020 to 30th September 2020. Participants were hospitalized COVID-19 patients. Interventions included tocilizumab versus placebo/standard of care. The comparison will be between TCZ versus standard of care (SOC)/placebo. Inconsistency between the studies was evaluated with I2 and quality of the evidences were evaluated by Newcastle-Ottawa scale.ResultsBased on the inclusion criteria there were 24 retrospective studies involving 5686 subjects were included. The outcomes of the meta-analysis have revealed that the TCZ has reduced the mortality (M-H,RE-OR −0.11(−0.18 to −0.04) 95% CI, p =0.001, I2 =88%) and increased the incidences of super-infections (M-H, RE-OR 1.49(1.13 to 1.96) 95% CI, p=0.004, I2=47%). However, there is no significant difference in ICU admissions rate (M-H, RE-OR −0.06(−0.23 to 0.12), I2=93%), need of MV (M-H, RE-OR of 0.00(−0.06 to 0.07), I = 74%), LOS (IV −2.86(−0.91 to 3.38), I2=100%), LOS-ICU (IV: −3.93(−12.35 to 4.48), I2=100%), and incidences of pulmonary thrombosis (M-H, RE-OR 1.01 (0.45 to 2.26), I2=0%) compared to SOC/control.ConclusionBased on cumulative low to moderate certainty evidence shows that TCZ could reduce the risk of mortality in hospitalized patients. However, there is no statistically significant difference observed between the TCZ and SOC/control groups in other parameters.

Background: Melanoma is the most serious lethal skin cancer, affects the melanin producer cells (melanocytes). Surgery is the most common treatment, whereas for the advance stage the development of a treatment is recommended. BRAF (Dabrafenib and Vemurafenib) inhibitor or MEK inhibitor (Trametinib) is used as the most frequently targeted therapy of melanoma due to more than 80% patient with positive BRAF mutation. In this review, those treatments will be investigated systematically to identify their clinical outcome.Method: This systematic literature review (SLR) was performed from Cochrane, Science Direct, Google Scholar, and Pubmed. Cochrane Risk-of-Bias Tool RoB2 is used to assess RCT studies and New-castle Ottawa Scale Assessment to assess cohort studies by 3 different assessors. Data analysis was carried out by using Review Manager (RevMan 5.4). Heterogenicity test was assessed by I2  and Chi2 statisticResult: There are 20 studies used in this article (13 RCT and 7 cohorts). The overall survival (OS) and progression-free survival (PFS) of study that using targeted therapy (vemurafenib, trametinib, or dabrafenib) compare other therapies (chemotherapy, immunotherapy,etc) showed risk ratio (RR) was 1.12 (95%CI 1.07,1.17;  I2=100%; p<0,00001). The OS and PFS with monotherapy compare of vemurafenib, trametinib, or dabrafenib with combination therapy showed RR was 1.09 (95%CI.06,1.13;I2=99%; p<0,00001). Conclusion: BRAF and MEK targeted therapy has a good prognosis for a patient with a positive BRAF gene mutation and could be combined with other therapy for a better clinical outcome rather than monotherapy.Keyword: melanoma, dabrafenib, vemurafenib, and trametinib
