ObjectiveThe objective of this systematic review and meta-analysis was to determine the prognostic value of memory CD8(+) T cells in cancer patients with immunotherapy.MethodsEMBASE, MEDLINE (PubMed), and Web of Science databases were searched to identify suitabile articles published before March 2021. Risk of bias on the study level was assessed using the Cochrane Bias Risk Assessment Tool. The hazard ratios (HRs) and 95% confidence intervals (CIs) of pooled progression-free survival (PFS) and overall survival (OS) were calculated using RevMan 5.4 to evaluate the prognostic impact of memory CD8(+) T cells.ResultsIn total, nine studies were included in the final analysis. High levels of memory CD8(+) T cells were significantly closely correlated with better progression-free survival (PFS) and overall survival (OS) of cancer patients with immunotherapy (PFS, HR 0.64, 95% CI 0.53–0.78; OS, HR 0.37, 95% CI 0.21–0.65). Memory CD8(+) T cells still have significant prognostic value in cancer patients given immunotherapy alone after excluding of other interfering factors such as chemotherapy, radiotherapy, and targeted therapy (PFS, HR 0.65, 95% CI 0.48–0.89; OS, HR 0.23, 95% CI 0.13–0.42). However, high memory CD8(+) T cells levels did not correspond to a longer PFS or OS in cancer patients with non-immunotherapy (PFS, HR 1.05, 95% CI 0.63–1.73; OS, HR 1.29, 95% CI 0.48–3.48). Thus, memory CD8(+) T cells might be a promising predictor in cancer patients with immunotherapy.ConclusionsThe host’s overall immune status, and not only the tumor itself, should be considered to predict the efficacy of immunotherapy in cancer patients. This study is the first to show the significant prognostic value of memory CD8(+) T cells in immunotherapy of cancer patients through systematic review and meta-analysis. Thus, the detection of memory CD8(+) T cells has a considerable value in clinical practice in cancer patients with immunotherapy. Memory CD8(+) T cells may be promising immunotherapy targets.

An increased presence of CD206-expressing tumor associated macrophages in solid cancers was proposed to be associated with worse outcomes in multiple types of malignancies, but contradictory results are published. We performed a reproducible systematic review and meta-analysis to provide increased evidence to confirm or reject this hypothesis following the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. The Embase, Web of Science, and MEDLINE-databases were systematically searched for eligible manuscripts. A total of 27 papers studying the prognostic impact of CD206 in 14 different tumor types were identified. Meta-analyses showed a significant impact on the overall survival (OS) and disease-free survival (DFS). While no significant differences were revealed in progression-free survival (PFS) and disease-specific survival (DSS), a shift towards negative survival was correlated with increased CD206-expresion. As a result of the different tumor types, large heterogeneity was present between the different tumor types. Subgroup analysis of hepatocellular carcinoma and gastric cancers revealed no heterogeneity, associated with a significant negative impact on OS in both groups. The current systematic review displays the increased presence CD206-expressing macrophages as a significant negative prognostic biomarker for both OS and DFS in patients diagnosed with solid cancers. Because a heterogenous group of tumor types was included in the meta-analysis, the results cannot be generalized. These results can, however, be used to further lead follow-up research to validate the specific prognostic value of CD206 in individual tumor types and therapeutic approaches.

BackgroundStudies on the prognostic value of the soluble programmed death ligand 1 (sPD-L1) in cancer patients have not yielded consistent results.ObjectiveThis meta-analysis was performed to assess the association between sPD-L1 and the prognosis of cancer patients.MethodsPublished articles in Pubmed, EMBASE, and Cochrane clinical trial databases were searched from the inception to September 2020. Overall survival (OS), progression-free survival (PFS), recurrence-free survival (RFS), and disease-free survival (DFS) data were evaluated using a hazard ratio (HR) at 95% confidence interval (95% CI).ResultsA total 31 studies involving 17 tumors and 3,780 patients were included. The overexpression of sPD-L1 was associated with shorter OS (HR 1.85, 95% CI 1.59–2.15, I2 = 33%). High sPD-L1 had worse PFS (HR 2.40, 95% CI 1.55–3.72, I2 = 83%), and worse DFS (HR 2.92, 95% CI 2.02–4.29, I2 = 40%), without significant statistical difference in RFS (HR 2.08, 95% CI 0.99–4.40, I2 = 0%).ConclusionsHigh sPD-L1 levels were associated with worse survival prognosis in cancer patients. The sPD-L1 may be a potential prognostic, non-invasive, and dynamic monitoring biomarker for cancers in the future.

Abstract Background: Some studies have found that immune cell spatial structures, also known as tertiary lymphoid structures (TLSs), may have prognostic value in cancer. However, these studies all had insufficient sample sizes and inconsistent conclusions. To overcome these problems and draw conclusions, a systematic review and meta-analysis was conducted to determine the prognostic impact of TLSs in cancer.Methods: PubMed, Web of Science, and Embase databases were searched to identify eligible articles published before April 2021. Two authors assessed each record, ensuring that the PICOS framework was met, and risk of bias on the study level was assessed using the Cochrane Bias Risk Assessment Tool. We then performed a meta-analysis using Review Manager 5.3 program to obtain a comprehensive estimate of the prognostic role of TLSs. Results: In total, 28 studies were included in our analysis. We found that in comparison to cancer patients with low TLSs levels, those with high TLSs levels had a better overall survival (OS, hazard ratio [HR]: 0.48, 95% confidence interval [CI]: 0.40-0.57, p<0.00001) and disease-free survival (DFS, HR: 0.52, 95% CI: 0.42-0.63, p<0.00001). Surprisingly, after receiving immune checkpoint inhibitors (ICIs) therapy, cancer patients with high TLSs levels also had a better OS (HR, 0.28; 95% CI, 0.16-0.48; p<0.00001). Furthermore, our subgroup analysis showed that the density of DC-Lamp+ dendritic cells (DCs) and CD20+ B cells in TLSs represented better clinical outcomes.Conclusion: To the best of our knowledge, this study is the first meta-analysis to show the significant prognostic value of TLSs in cancer, to date. Moreover, TLSs are expected to be a potential marker for predicting anti-tumor immune response, which may help clinicians to select patients with cancer who are sensitive to immunotherapy. In addition to their concentration, TLSs components also had strong prognostic value. In particular, the study may provide a novel therapeutic target for patients with cancer and provide a new theoretical basis for future research on tumor immunotherapy.

Objective. We performed a meta-analysis of available studies to assess the prognostic value of circulating tumor cells detected by cytological methods for patients with gastric cancer. Methods. Two authors systematically searched the studies independently with key words in PubMed, MEDLINE, EMBASE, Science Citation Index Expanded, and Cochrane Library (from inception to April 2016). The estimated hazard ratio, risk ratio, odds ratio, and their 95% confidence intervals were set as effect measures. All analyses were performed by STATA 12.0. Results. Sixteen studies were included in this meta-analysis. CTCs-high status was significantly associated with poor overall survival (HR=2.23, 95% CI: 1.86–2.66) and progression-free survival (HR=2.02, 95% CI: 1.36–2.99). CTCs-high status was also associated with depth of infiltration (OR = 2.07, 95% CI: 1.16–3.70), regional lymph nodes metastasis (OR = 1.85, 95% CI: 1.26–2.71), and distant metastasis (OR = 2.83, 95% CI: 1.77–4.52). For unresectable gastric cancer patients, CTCs-high status was significantly associated with poor overall survival, progression-free survival, and disease control rate before and during chemotherapy group. Conclusions. Our meta-analysis has evidenced the significant prognostic value of CTCs detected for both PFS and OS in gastric cancer patients. For patients treated with chemotherapy alone, we proved that CTCs detected by cytological method showed a significant prognostic value and poor response to chemotherapy.

Abstract Purpose: To investigate the prognostic value of pretreatment albumin to alkaline phosphatase ratio (AAPR) in human cancers.Methods: Several electronic databases were searched up to Jan 4, 2020 for relevant studies. The prognostic value of AAPR were assessed by pooled hazard ratios (HRs) with their corresponding 95% confidence intervals (CIs). The endpoint events included the overall survival (OS), disease-free survival (DFS), cancer-specific survival (CSS) and progression-free survival (PFS).Results: A total of 15 articles involving 20 studies with 6062 cancer patients were included. Our results proved that low pretreatment AAPR was related with poor OS (HR=1.83, 95% CI: 1.66-2.02; P<0.001), DFS (HR=1.97, 95% CI: 1.49-2.61; P<0.001), CSS (HR=1.88, 95% CI: 1.37-2.56; P<0.001) and PFS (HR=1.74, 95% CI: 1.24-2.43; P=0.001). In addition, the significant correlation between pretreatment AAPR and OS was not affected by the treatment strategy and tumor pathological type.Conclusion: Low pretreatment AAPR is related to poor prognosis in human cancers, and AAPR could be served as a promising prognostic indicator in cancer patients.

Abstract Background Tumor-infiltrating lymphocytes (TILs) are major participants in the tumor microenvironment. The prognostic value of TILs in patients with pancreatic cancer is still controversial. Methods The aim of our meta-analysis was to determine the impact of FoxP3+Treg cells on the survival of pancreatic cancer patients. We searched for related studies in PubMed, EMBASE, Ovid, and Cochrane Library from the time the databases were established to Mar 30, 2017. We identified studies reporting the prognostic value of FoxP3+Treg cells in patients with pancreatic cancer. Overall survival (OS) and disease-free survival (DFS)/progression-free survival (PFS)/relapse-free survival (RFS) were investigated by pooling the data. The pooled hazard ratios (HRs) with 95% confidence intervals (95% CI) were used to evaluate the association between FoxP3+Treg cells and survival outcomes of pancreatic cancer patients. A total of 972 pancreatic cancer patients from 8 studies were included in our meta-analysis. Results High levels of infiltration with FoxP3+Treg cells were significantly associated with poor OS (HR=2.13; 95% CI 1.64–2.77; P<0.05) and poor DFS/PFS/RFS (HR=1.70; 95% CI 1.04 ~ 2.78; P< 0.05). Similar results were also observed in the peritumoral tissue; high levels of FoxP3+Treg cells were associated with poor OS (HR =2.1795% CI, CI 1.50–3.13). Conclusion This meta-analysis indicated that high levels of intratumoral or peritumoral FoxP3+Treg cell infiltration could be recognized as a negative factor in the prognosis of pancreatic cancer.

Abstract Introduction: The detection of abnormal protein bands (APB) different from the original monoclonal protein in patients with multiple myeloma (MM) who underwent stem cell transplantation and/or chemotherapy has been reported. These atypical serum immunofixation patterns may be monoclonal (also termed secondary monoclonal gammopathy of undetermined significance) or oligoclonal bands (OB). The prognostic significance of this phenomenon remains controversial. This systematic review and meta-analysis aimed to summarize and analyze the evidence for the association between APB with survival in MM patients. Methods: A systematic search of PubMed, Cochrane, Google Scholar, Medline-Ovid, CINAHL, and ERIC, was conducted using relevant search terms. All studies were screened using predefined selection criteria and critically appraised for quality assessment following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. All studies that described the presence of APB, defined as monoclonal spike with heavy or light chain immunoglobulin distinct from the original paraprotein at initial diagnosis of MM, and its associations with survival were included. Studies that reported multivariate adjusted hazard ratios (HR) were further included for meta-analysis. Random-effects model was used to synthesize the pooled HR estimate for the association of APB with survival. Cochran's Q statistics and I2 tests were used to evaluate statistical heterogeneity. Results: A total of 24 out of 181 eligible studies were included for qualitative synthesis. Four studies (including 1115 patients) that reported HR estimates were included in the final meta-analysis. The random-effect summary HR for the progression-free survival among patients with APB was 0.44 (95% CI, 0.31-0.65) with no statistical heterogeneity (I2=0%, p=0.93). The pooled HR for the association with overall survival was 0.31 (95% CI, 0.14-0.66) with moderate statistical heterogeneity (I2=45%; p=0.16) for patients with APB. One study (Silva et al, 2017) only included patients with at least very good partial response while the other three studies reported similar findings of higher occurrence of APB with complete response (Tovar et al, 2013; Jo et al, 2014; Zou et al, 2014). These results are also consistent with the presumed association of APB with complete response as suggested in other studies included in qualitative review. Conclusions: This study indicated a potential prognostic value of APB for favorable outcomes in the context of both overall and progression-free survival in MM patients after treatment. Further research is needed to evaluate the prognostic impact of the sole emergence of APB irrespective of treatment response. Figure 1 Figure 1. Disclosures Jamshed: Takeda: Honoraria.

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.
