Meta-Analysis Review
BACKGROUND
Interleukin-36s (IL-36s) are a category of inflammatory cytokines and an increasing number of studies over the past decade have found that different kinds of IL-36s play different roles in cancers. This systematic review and meta-analysis aimed to evaluate the prognostic value of IL-36s in different cancer types.
METHOD
Two reviewers independently searched in PubMed, Cochrane Library and EMBASE up to December 13, 2022. We extracted the hazard ratio (HR) and the confidence intervals (CIs) of the related prognostic outcomes and analyzed the pooled HR.
RESULTS
We included 12 studies including 1925 patients. In all, six studies including IL-36α, five including IL-36γ and one including IL-36β. A high expression of IL-36α was associated with better overall survival (OS) (HR = 0.48, 95 %CI: 0.37-0.62, P < 0.001) of cancer patients. The expression of IL-36γ was not related with cancers. Further, subgroup analysis showed that the expression of IL-36γ had no correlation with the OS of colorectal cancer (CRC) and non‑small cell lung cancer (NSCLC) patients. Interestingly, a high expression of IL-36γ played contrasting prognostic roles in hepatocellular carcinoma (HCC) (HR = 0.43, 95 %CI: 0.27-0.69, P < 0.001) patients and gastric cancer (GC) (HR = 1.58, 95 %CI: 1.33-1.87, P < 0.001) patients. The only IL-36β related study showed the expression of IL-36β was not correlated with the prognosis of CRC patients (P > 0.05).
CONCLUSION
IL-36α, IL-36β and IL-36γ possibly play different roles in different cancers. High expression of IL-36α may be associated with good prognostic value in cancer patients, especially in CRC patients. The association between cancers prognosis and expression of IL-36β or IL-36γ needs further evaluation. These conclusions need more clinical prognostic data for confirmation.

Meta-Analysis
OBJECTIVE
Our study represents the first meta-analysis conducted to evaluate the prognostic utility of the baseline prognostic nutritional index (PNI) in patients with gastrointestinal cancer (GIC) who received immune checkpoint inhibitor (ICI) therapy.
METHODS
We searched PubMed, the Cochrane Library, EMBASE, and Google Scholar until April 23, 2023, to obtain relevant articles for this study. Our analysis examined several clinical outcomes, including overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR).
RESULTS
In this analysis, a total of 17 articles with 2883 patients were included. Our pooled results indicated that patients with high PNI levels had longer OS (HR: 0.530, 95% CI: 0.456-0.616, < 0.001) and PFS (HR: 0.740, 95% CI: 0.649-0.844, < 0.001), as well as higher ORR (OR: 1.622, 95% CI: 1.251-2.103, < 0.004) and DCR (OR: 1.846, 95% CI: 1.428-2.388, < 0.001). Subgroup analysis showed that PNI cutoff values of 40 to 45 showed greater predictive potential. Subgroup analysis also confirmed that the above findings still hold true in patients with esophageal cancer, gastric cancer, and hepatocellular carcinomas.
CONCLUSION
The PNI were reliable predictors of outcomes in GIC patients treated with ICIs.

Meta-Analysis
Thyroid cancer (TC) represents the most common endocrine malignant tumor. Liquid biopsy has been suggested as a new and accurate biomarker in cancer. This systematic review analyzes the existing literature on circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), cell-free DNA integrity index (cfDI), and their potential as biomarkers for TC, including the subtypes: differentiated (papillary and follicular), medullary, and anaplastic. A systematic search was performed in PubMed, Embase, and Cochrane databases for published articles in English between 1 January 1970 and 6 September 2022 (PROSPERO: CRD42022358592). The literature search generated a total of 635 articles. In total, 36 articles were included (patients = 2566). Four studies reported that higher levels of CTCs were associated with metastases and worse prognosis. Nineteen studies found the presence of mutated ctDNA in TC patients. The diagnostic accuracy in detecting BRAFV600E as ctDNA was determined in 11 studies regarding papillary TC. The pooled sensitivity, specificity, and diagnostic odds ratio were estimated at 56% (95% CI 36-74), 91% (95% CI 84-95) and 12 (95% CI 4.09-33.11), respectively. Four studies concluded that the cfDI was higher in patients with TC compared to benign thyroid lesions and healthy controls. The detection of CTCs, ctDNA, and cfDI may have a potential prognostic value in TC in relation to diagnosis, disease progression, and treatment efficacy. Despite the promising potential of CTCs, ctDNA, and cfDI in TC management, limitations hinder direct comparison and generalization of findings. Standardized methodologies, larger patient cohorts, and a consensus on relevant markers are needed to validate their clinical applicability and enhance TC management.

Meta-Analysis
IMPORTANCE
Growing research suggests that the prevalence of cutaneous immune-related adverse events (cirAEs) is associated with favorable outcomes among individuals with cancer who receive immune checkpoint inhibitor (ICI) treatment.
OBJECTIVE
To identify whether the presence of cirAEs and their subtypes subsequent to ICI administration is associated with enhanced cancer prognosis.
DATA SOURCES
The PubMed, Embase, Cochrane Library, and Web of Science databases were searched for publications examining the association between cirAE development during ICI treatment and subsequent cancer prognosis. The initial search was limited to English-language publications from database inception until December 31, 2022; a subsequent search was performed on May 21, 2023.
STUDY SELECTION
Two reviewers independently scrutinized the identical articles and included those that constituted original research evaluating the association between cirAE development and cancer prognosis.
DATA EXTRACTION AND SYNTHESIS
The search terms, study objectives, and methodological protocols were defined before study initiation. The aforementioned 2 reviewers performed data extraction independently and resolved discrepancies through agreement. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis and the Meta-analysis of Observational Studies in Epidemiology reporting guidelines. The protocol was prospectively registered with PROSPERO. Data analyses were conducted between May 21 and June 1, 2023.
MAIN OUTCOMES AND MEASURES
The major outcome end points were overall survival (OS) and progression-free survival (PFS). Subgroup analyses were also conducted according to cirAE type, cancer type, geographic region, study design, and ICI type. Given the heterogeneity inherent in the included studies, a DerSimonian-Laird random-effects model was adopted.
RESULTS
This systematic review and meta-analysis included 23 studies with a total of 22 749 patients treated with ICIs. The occurrence of cirAEs was associated with improved OS (hazard ratio [HR], 0.61 [95% CI, 0.52-0.72]; P < .001) and PFS (HR, 0.52 [95% CI, 0.41-0.65]; P < .001). Consistent results were observed across all subgroups stratified by study design, geographic region, ICI type, and cancer type, aligning with the overall estimate of OS and PFS improvement. However, no statistically significant differences were identified in terms of PFS within studies conducted in the US.
CONCLUSIONS AND RELEVANCE
In this systematic review and meta-analysis, the presence of cirAEs and their subtypes was associated with improved prognosis for individuals with cancer undergoing ICI treatment. These findings suggest that cirAEs may have useful prognostic value in ICI treatment.

Meta-Analysis
Objective: to explore the association between serum vitamin D level and the occurrence and pathological grade of gastric cancer. Material a nd methods: search PubMed, Embase, Web of Science, Cochrane and Chinese database; all articles about the association between serum vitamin D levels and gastric cancer published before July 2021. Results: 10 trials with 1159 cases of gastric cancer patients and 33,387 cases of regular control patients were analyzed. The serum vitamin D level of the gastric cancer group (15.56 ± 7.46 ng/ml) was lower than in the control group (17.60 ± 1.61 ng/ml), and the difference was statistically significant. The patients with gastric cancer, clinical stage III/IV (16.19 ± 8.04 ng/ml) had lower vitamin D levels than those with stage I/II (19.61 ± 9.61 ng/ml), and the patients with low differentiation of gastric cancer (17.5 ± 9.5 ng/ml) had lower levels than those with well- or moderately-differentiated cancer (18.04 ± 7.92 ng/ml). The patients with lymph node metastasis (19.41 ± 8.63 ng/ml) had lower vitamin D levels than the patients without lymph node metastasis (20.65 ± 7.96 ng/ml), and the difference was statistically significant. Conclusion: vitamin D levels were negatively associated with gastric cancer. Vitamin D levels were significantly associated with different clinical stages, degrees of differentiation, and lymph node metastasis, suggesting that low vitamin D levels might predict poor prognosis in gastric cancer.

BACKGROUND
Delta-like ligand 3 (DLL3), a member of the Notch pathway, has been identified as a potential therapeutic target as it is highly expressed in small cell lung cancer (SCLC), a subtype accounting for 15% of lung cancer cases.
OBJECTIVE
A systematic literature review (SLR) was conducted to understand the prevalence and prognostic impact of DLL3 expression on survival of patients with SCLC and treatment response.
PATIENTS AND METHODS
Systematic literature searches were conducted across multiple databases to capture studies of any SCLC population that evaluated DLL3 expression. Specific outcomes of interest included prevalence of DLL3 expression, method of expression analysis, and impact on outcome, including treatment response and survival (overall, progression-free, disease-free) according to varying levels of DLL3 expression/positivity. Standard risk of bias tools were used to evaluate study quality.
RESULTS
Among the 30 included studies, the most common DLL3 testing method was immunohistochemistry (N = 26, 86.7%). For comparability, results focused on the 13 (22.3%) studies that used the Ventana DLL3 (SP347) immunohistochemistry assay. The prevalence of DLL3 positivity ranged from 80.0-93.5% for studies using a threshold of ≥ 1% of tumor cells (N = 4) and 58.3-91.1% for studies with a ≥ 25% threshold (N = 4). DLL3 expression was generally categorized as high using cutoffs of ≥ 50% (prevalence range: 45.8-79.5%; N = 6) or ≥ 75% (prevalence range: 47.3-75.6%; N = 5) of cells with positivity. Two studies used an H-score of ≥ 150 to define high DLL3 expression with prevalence ranging from 33.3-53.1%. No consistent associations were seen between DLL3 expression level and patient age, sex, smoking history, or disease stage. Two studies reported change in DLL3 expression category (high versus low) before and after chemotherapy. No statistically significant differences were reported between DLL3 expression groups and survival (overall, progression-free, or disease-free) or treatment response.
CONCLUSIONS
There is a high prevalence of DLL3 expression in SCLC. Further research and analytical methods may help to characterize different populations of patients with SCLC based on DLL3 expression. While no significant prognostic factor in the included studies was identified, additional cohort studies using standardized methodology, with longer follow-up, are needed to better characterize any potential differences in patient survival or response by DLL3 expression level in SCLC.

Meta-Analysis Review
BACKGROUND
Inflammation has been associated with tumor development and circulating inflammatory biomarkers have been proposed as possible predictors of recurrence of several solid tumors. However, the role of inflammation markers in differentiated thyroid carcinoma (DTC) is still uncertain.
OBJECTIVE
This meta-analysis aimed to assess the prognostic value of neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) in patients with DTC.
METHODS
Studies investigating the association between survival and preoperative circulating inflammatory markers in DTC patients were included. The primary outcome was disease-free survival (DFS). Cumulative logarithms of the hazard ratio (log-HRs) with 95% CI were calculated through the inverse variance method using a random-effects model.
RESULTS
A total of 7599 patients with a mean age of 48.89 (95% CI 44.16-53.63) were included. The estimated pooled log-HRs for DFS were 0.07 for NLR (95% CI -0.12-0.26; p = 0.43), -0.58 for LMR (95% CI -1.21-0.05; p = 0.06), and 0.01 (95% CI 0-0.01; p = 0.21) for PLR.
CONCLUSIONS
Our meta-analysis showed no association between NLR, PLR, LMR and DFS in DTC; however, more prospective data are needed to better define the association between inflammatory status and prognosis of DTC.

Meta-Analysis
BACKGROUND
The receptor for activated C kinase 1 (RACK1) expression is associated with clinicopathological characteristics and the prognosis of various cancers; however, the conclusions are controversial. As a result, this study aimed to explore the clinicopathological and prognostic values of RACK1 expression in patients with cancer.
METHODOLOGY
PubMed, Embase, Web of Science, Cochrane Library, and Scopus were comprehensively explored from their inception to April 20, 2023, for selecting studies on the clinicopathological and prognostic role of RACK1 in patients with cancer that met the criteria for inclusion in this review. Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were used to assess the prognosis-predictive value of RACK1 expression, while pooled odds ratios (ORs) and 95% CIs were used to evaluate the correlation between RACK1 expression and the clinicopathological characteristics of patients with cancer. The quality of the included studies was evaluated using the Newcastle-Ottawa Scale.
RESULTS
Twenty-two studies (13 on prognosis and 20 on clinicopathological characteristics) were included in this systematic review and meta-analysis. The findings indicated that high RACK1 expression was significantly associated with poor overall survival (HR = 1.62; 95% CI, 1.13-2.33; = 0.009; I = 89%) and reversely correlated with disease-free survival/recurrence-free survival (HR = 1.87; 95% CI, 1.22-2.88; = 0.004; I = 0%). Furthermore, increased RACK1 expression was significantly associated with lymphatic invasion/N+ stage (OR = 1.74; 95% CI, 1.04-2.90; = 0.04; I = 79%) of tumors.
CONCLUSIONS
RACK1 may be a global predictive marker of poor prognosis in patients with cancer and unfavorable clinicopathological characteristics. However, further clinical studies are required to validate these findings.

Prognostic and Clinicopathological Significance of Epidermal Growth Factor Receptor (EGFR) Expression in Oral Squamous Cell Carcinoma: Systematic Review and Meta-Analysis.
The aim of this systematic review and meta-analysis was to evaluate the current evidence in relation to the clinicopathological and prognostic significance of epidermal growth factor receptor (EGFR) overexpression in patients with oral squamous cell carcinoma (OSCC). We searched MEDLINE/PubMed, Embase, Web of Science, and Scopus for studies published before November 2022. We evaluated the quality of primary-level studies using the QUIPS tool, conducted meta-analyses, examined inter-study heterogeneity via subgroup analyses and meta-regressions, and performed small-study effects analyses. Fifty primary-level studies (4631 patients) met the inclusion criteria. EGFR overexpression was significantly associated with poor overall survival (hazard ratio [HR] = 1.38, 95% confidence intervals [CI] = 1.06-1.79, = 0.02), N+ status (odds ratio [OR] = 1.37, 95%CI = 1.01-1.86, = 0.04), and moderately-poorly differentiated OSCC (OR = 1.43, 95% CI = 1.05-1.94, = 0.02). In addition, better results were obtained by the application of a cutoff point ≥10% tumor cells with EGFR overexpression ( < 0.001). In conclusion, our systematic review and meta-analysis supports that the immunohistochemical assessment of EGFR overexpression may be useful as a prognostic biomarker for OSCC.

Meta-Analysis Review
BACKGROUND/AIM
Low human epidermal growth factor receptor 2 expression (HER2-low: 1+/2+ by immunohistochemistry without HER2 amplification) is emerging as defining a specific breast cancer (BC) subgroup owing to its distinct biological features. However, its prognostic role has not been confirmed in clinical practice. We conducted a systematic review and meta-analysis to determine the prognostic role of HER2-low status in patients with estrogen receptor-positive (ER+) early BC.
MATERIALS AND METHODS
We searched PubMed, EMBASE, and the Cochrane Library for prospective or retrospective studies that reported data on overall (OS) or disease-free (DFS) survival for HER2-low compared to HER2-negative BC. Data were pooled using hazard ratios (HR) with confidence intervals (CI) for OS/DFS of HER2-low vs. HER2-negative subgroups according to the random-effects model. OS was the primary outcome measure, and DFS and pathological complete response were the secondary endpoints.
RESULTS
An analysis was made of 25 studies collected, including 34,965 patients with HER2-low BC. A HER2-low status was associated with an HR for OS of 0.83 (95% CI=0.76-0.9, p<0.0.01). Similarly, a pooled HR of 0.89 (95% CI=0.840.94, p<0.0.01) showed that patients with HER2-low BC had an increased DFS. Pathological complete response was significantly lower in HER2-low BC in 13 studies (OR=0.72, 95% CI=0.58-0.91; p<0.01).
CONCLUSION
Based on these data, HER2-low status should be identified as a potential prognostic factor in early stage ER+ BC. This should be taken into account when considering treatment in (neo)adjuvant settings, and it should be a potential stratification factor in future investigations.
