Background. Metabolism in the tumor microenvironment can play a critical role in tumorigenesis and tumor aggression. Metabolic coupling may occur between tumor compartments; this phenomenon can be prognostically significant and may be conserved across tumor types. Monocarboxylate transporters (MCTs) play an integral role in cellular metabolism via lactate transport and have been implicated in metabolic synergy in tumors. The transporters MCT1 and MCT4 are regulated via expression of their chaperone, CD147.Methods. We conducted a meta-analysis of existing publications on the relationship between MCT1, MCT4, and CD147 expression and overall survival and disease-free survival in cancer, using hazard ratios derived via multivariate Cox regression analyses.Results. Increased MCT4 expressions in the tumor microenvironment, cancer cells, or stromal cells were all associated with decreased overall survival and decreased disease-free survival (p<0.001for all analyses). Increased CD147 expression in cancer cells was associated with decreased overall survival and disease-free survival (p<0.0001for both analyses). Few studies were available on MCT1 expression; MCT1 expression was not clearly associated with overall or disease-free survival.Conclusion. MCT4 and CD147 expression correlate with worse prognosis across many cancer types. These results warrant further investigation of these associations.

Sine Oculis Homeobox Homolog 1 (SIX1) is reported to promote cancer initiation and progression in many preclinical models and is demonstrated in human cancer tissues. However, the correlation between SIX1 and cancer patients’ prognosis has not yet been systematically evaluated. Therefore, we performed a systematic review and meta-analysis in various human cancer types and extracted some data from TCGA datasets for further verification and perfection. We constructed 27 studies and estimated the association between SIX1 expression in various cancer patients’ overall survival and verified with TCGA datasets. Twenty-seven studies with 4899 patients are include in the analysis of overall, and disease-free survival, most of them were retrospective. The pooled hazard ratios (HRs) for overall and disease-free survival in high SIX1 expression patients were 1.54 (95% CI: 1.32-1.80, P&lt;0.00001) and 1.83 (95% CI: 1.31-2.55, P=0.0004) respectively. On subgroup analysis classified in cancer type, high SIX1 expression was associated with poor overall survival in patients with hepatocellular carcinoma (HR 1.50; 95% CI: 1.17-1.93, P =0.001), breast cancer (HR 1.31; 95% CI: 1.10-1.55, P =0.002) and esophageal squamous cell carcinoma (HR 1.89; 95% CI: 1.42-2.52, P&lt;0.0001). Next, we utilized TCGA online datasets, and the consistent results were verified in various cancer types. SIX1 expression indicated its potential to serve as a cancer biomarker and deliver prognostic information in various cancer patients. More works still need to improve the understandings of SIX1 expression and prognosis in different cancer types.

Head and neck squamous cell carcinoma (HNSCC) rank seventh among the most common type of malignant tumor worldwide. Various evidences suggest that transcriptional factors (TFs) play a critical role in modulating cancer progression. However, the prognostic value of TFs in HNSCC remains unclear. Here, we identified a risk model based on a 12-TF signature to predict recurrence-free survival (RFS) in patients with HNSCC. We further analyzed the ability of the 12-TF to predict the disease-free survival time and overall survival time in HNSCC, and found that only NR5A2 down-regulation was strongly associated with shortened overall survival and disease-free survival time in HNSCC. Moreover, we systemically studied the role of NR5A2 in HNSCC and found that NR5A2 regulated HNSCC cell growth in a TP53 status-dependent manner. In p53 proficient cells, NR5A2 knockdown increased the expression of TP53 and activated the p53 pathway to enhance cancer cells proliferation. In contrast, NR5A2 silencing suppressed the growth of HNSCC cells with p53 loss/deletion by inhibiting the glycolysis process. Therefore, our results suggested that NR5A2 may serve as a promising therapeutic target in HNSCC harboring loss-of-function TP53 mutations.

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.

Abstract Objective To evaluate local recurrence, metastases, and survival outcomes of `wait and watch’ (WW) strategy and local excision (LE) of tumours, in comparison to the present standard practice of total mesorectal excision (TME) for locally advanced rectal cancers. Data Sources MEDLINE, EMBASE, PubMed databases, and sources of Grey literature. Study Selection Randomised and non-randomised prospective studies, retrospective studies with propensity-score-matched analyses. Data Extraction and Synthesis These were carried out independently by two reviewers. A random-effects methodology was used for meta-analyses. Data was presented keeping with the 27-item PRISMA checklist. Main Outcomes The primary outcomes of interest were local recurrence, distant metastases, disease-free-survival and overall-survival, which were assessed in comparison to those associated with radical surgeries (TME). Results 7 of the 16 studies in the systematic review were included for the quantitative synthesis and meta-analysis. Local recurrence rates were comparable amongst patients in WW group and LE group to those undergoing TME. [Risk ratio (RR) 3.07/1.41; 95% Confidence Interval (CI) 0.86-10.95/0.66-3.01; P = 0.08/P=0.89 respectively]. Rates of distant metastases in the WW group and LE group were comparable to those undergoing TME [RR = 0.71/0.94; 95% CI 0.22-2.30/0.55-1.61; P = 0.56/ P = 0.83 respectively]. The median 3-year disease-free survival among patients undergoing WW, LE procedure, and TME were 88%, 80%, and 78.2% respectively; and the median 3-year overall survival among the three groups were 96%, 93%, and 89.5% respectively. Conclusions and Relevance Organ-preservation strategies appear to be a viable treatment option in the management of rectal-cancers. Further research is warranted to provide stronger levels of evidence on organ-preservation strategies.

Background: The pretreatment prognostic nutritional index has been considered a potential prognostic biomarker in patients with non-small cell lung cancer (NSCLC), but this remains controversial. Therefore, we performed a meta-analysis to systematically assess the prognostic value of the prognostic nutritional index in patients with NSCLC. Methods: We systematically searched PubMed, EMBASE, Web of Science, and CNKI. The hazard ratios (HRs) with their corresponding 95% confidence intervals (CIs) were used to evaluate the link between the prognostic nutritional index and the oncological outcomes of patients with NSCLC, including overall survival, disease-free survival/recurrence-free survival, and progression-free survival. Results: Fifteen studies were included in this meta-analysis. Twelve of these studies explored the association between the prognostic nutritional index and the overall survival of patients with NSCLC. Our pooled analysis indicated that a low prognostic nutritional index was significantly related to adverse overall survival (HR 1.61; 95% CI 1.44, 1.81; P < 0.001). Our results also showed that the prognostic nutritional index was a negative predictor for disease-free survival/recurrence-free survival, and progression-free survival in patients with NSCLC. Conclusion: Our meta-analysis demonstrated that there was a close association between the prognostic nutritional index value and prognosis in NSCLC patients and that the prognostic nutritional index may act as a useful prognostic biomarker in NSCLC patients.

3548 Background: Colon cancer is potentially curable by surgery in the early stages of the disease. Adjuvant chemotherapy improves disease-free and overall survival in patients with stage III disease, but the magnitude of benefit in stage II colon cancer is less clear. A previous Cochrane systematic review and meta-analysis (SR/MA) found improved disease-free, but not overall survival (Figueredo et al., 2008). An updated SR/MA was performed to determine the effects of adjuvant chemotherapy on disease-free and overall survival in patients with stage II colon cancer. Methods: Relevant databases (MEDLINE, EMBASE, and Cochrane) were independently searched by all authors, using the same search strategy employed in the original study (1/1988 to 9/2012). Randomized trials containing data on stage II colon cancer patients undergoing adjuvant 5-fluorouracil (5FU) chemotherapy versus observation were included. Pooled results were expressed as hazard ratios (HR) whenever possible, or risk ratios (RR), with 95% confidence intervals (95%CI) using a random effects model. Results: Seven studies were identified, and included in the final SR/MA. Six of the 7 studies were included in the disease-free survival analysis (n=4587). Adjuvant 5FU was associated with better disease-free survival (RR 0.84 (95%CI 0.75-0.94)). All 7 studies (n=5353) were included in the overall survival analysis showing an improvement with adjuvant 5FU (HR 0.87 (95%CI 0.78-0.97)). There was no evidence of heterogeneity across the studies (I2 = 0% for all analyses). Conclusions: In stage II colon cancer, adjuvant 5FU chemotherapy statistically improves both disease-free and overall survival. Our SR/MA demonstrates, for the first time, an overall survival advantage with adjuvant chemotherapy in stage II colon cancer.

4585 Background: Adjuvant trials aim to integrate systemic therapy earlier to increase cure rates over surgery alone. Overall survival (OS) is a critical endpoint for these studies but requires long durations to events and significant patient resources. We explored the potential use of disease-free survival (DFS) as an intermediate readout for OS in the adjuvant setting for localized renal cell carcinoma (RCC). Methods: We performed a systematic literature review following the PRISMA guidelines. Inclusion criteria required randomized controlled trials (RCT) for adjuvant systemic therapy in localized RCC, which reported on both DFS and OS. Data on hazard ratio (HR) and 5-year event-free rate from Kaplan-Meier estimates were extracted. We performed a trial level meta-analysis and correlated these estimates for OS and DFS, weighted by the number of DFS events. R-square > 0.7 would indicate a strong correlation and potential for surrogacy. Results: Thirteen RCTs encompassing 6,473 patients treated with various forms of systemic therapy were eligible for the analyses. Minimum follow-up was 40 months. There was a moderate correlation between 5-year DFS and 5-year OS rates (R-square = 0.49, 95% CI:0.15-0.68) and between treatment effects as measured by DFS and OS hazard ratios (R-square = 0.44, 95% CI:0.00-0.69). Conclusions: Across trials of adjuvant systemic therapy for localized RCC, we observed a moderate correlation between 5-year DFS and OS rates and between treatment effects (HRs) on these endpoints. Further granularity may be achieved using individual patient data to assess different and earlier time points for surrogacy than are commonly reported. [Table: see text]

Purpose To develop a systematic review that would address the following question: Should patients with stage II colon cancer receive adjuvant therapy? Methods A systematic review was undertaken to locate randomized controlled trials comparing adjuvant therapy to observation. Results Thirty-seven trials and 11 meta-analyses were included. The evidence for stage II colon cancer comes primarily from a trial of fluorouracil plus levamisole and a meta-analysis of 1,016 patients comparing fluorouracil plus folinic acid versus observation. Neither detected an improvement in disease-free or overall survival for adjuvant therapy. A recent pooled analysis of data from seven trials observed a benefit for adjuvant therapy in a multivariate analysis for both disease-free and overall survival. The disease-free survival benefits appeared to extend to stage II patients; however, no P values were provided. A meta-analysis of chemotherapy by portal vein infusion has also shown a benefit in disease-free and overall survival for stage II patients. A meta-analysis was conducted using data on stage II patients where data were available (n = 4,187). The mortality risk ratio was 0.87 (95% CI, 0.75 to 1.01; P = .07). Conclusion There is preliminary evidence indicating that adjuvant therapy is associated with a disease-free survival benefit for patients with stage II colon cancer. These benefits are small and not necessarily associated with improved overall survival. Patients should be made aware of these results and encouraged to participate in active clinical trials. Additional investigation of newer therapies and more mature data from the presently available trials should be pursued.

Abstract Background: In clinical work, it has been increasingly found that the prognosis is still very different even for esophageal cancer (EC) patients with the same TNM stage. Tumor length has been analysed as a possible independent prognostic factor in many studies, but no unanimous conclusion has been reached. Therefore, this review used a meta-analysis to evaluate the association between tumor length and prognosis in EC patients.Methods: A systematic search for relevant articles was performed in PubMed, Web of Science, and Embase. Hazard ratios (HRs) and 95% confidence intervals (CIs) were used as effective measures to estimate the correlation between tumor length and prognosis, including overall survival, disease-free survival, progression-free survival, disease-specific survival, and cancer-specific survival. STATA 15.0 software was used to perform the meta-analysis and the data synthesis.Results: Finally, 41 articles with 28,973 patients were included in our study. The comprehensive statistical results showed that long tumors are an independent prognostic parameter associated with poor overall survival (OS) (HR=1.30; 95% CI: 1.21-1.40, p<.001) and disease-free survival (DFS) (HR=1.38; 95% CI: 1.18-1.61, p<.001) in EC patients. Subgroup analyses also suggested a significant correlation between long tumors and poor OS. Sensitivity analysis and publication bias evaluation confirmed the reliability and stability of the results. Similar results were obtained in the analyses of progression-free survival (PFS), disease-specific survival (DSS), and cancer-specific survival (CSS).Conclusion: The results of this meta-analysis showed that long tumors were related to poor OS, DFS, PFS, DSS and CSS in EC patients. Tumor length might be an important predictor of prognosis in EC patients, and it can be used as an independent staging index. Further well-designed and large-scale prospective clinical studies are needed to confirm these findings.

Abstract Backgrounds The inflammatory biomarker “C-reactive protein to albumin ratio (CAR)” has been reported to significantly correlate to a variety of human cancers. However, there are conflicting results regarding the prognostic value of CAR in colorectal cancer. Previous studies mainly assessed patients in Eastern countries, so their findings may not be applicable to the Western population. Therefore, this updated meta-analysis aimed to investigate the prognostic value of pre-treatment CAR and outcomes of patients with colorectal cancer. Methods We conducted a systematic search for eligible literature until October 31, 2020, using PubMed and Embase databases. Studies assessing pre-treatment CAR and outcomes of colorectal cancer were included. Outcome measures included overall survival, disease-free survival, progression-free survival, and clinicopathological features. The pooled hazard ratios (HR) with 95% confidence intervals (CI) were used as effective values. Results A total of 15 studies involving 6329 patients were included in this study. The pooled results indicated that a high pre-treatment CAR was associated with poor overall survival (HR 2.028, 95% CI 1.808−2.275, p < 0.001) and poor disease-free survival/progression-free survival (HR 1.768, 95% CI 1.321–2.365, p < 0.001). Subgroup analysis revealed a constant prognostic value of the pre-treatment CAR despite different study regions, sample size, cancer stage, treatment methods, or the cut-off value used. We also noted a correlation between high pre-treatment CAR and old age, male sex, colon cancer, advanced stage (III/IV), large tumor size, poor differentiation, elevated carcinoembryonic antigen levels, neutrophil-to-lymphocyte ratio, and the modified Glasgow prognostic score. Conclusions High pre-treatment CAR was associated with poor overall survival, disease-free survival, and progression-free survival in colorectal cancer. It can serve as a prognostic marker for colorectal cancer in clinical practice.
