Abstract Background : The prognostic value of pretreatment elevated platelet count remains controversial in lung cancer patients. We performed the present meta-analysis to determine the precise role of it in these patients.Methods: We performed a multiple search strategy in PubMed database, EMBASE and Cochrane Library to identify eligible studies. Disease-free survival (DFS) /Progress-free survival (PFS)/Time to progress(TTP) and Overall survival (OS) were used as outcomes with hazard ratio (HR) and its 95% confidence intervals (CIs). Heterogeneity among studies and publication bias were also evaluated.Results : A total of 39 studies including 16696 lung cancer patients were eligible in the analysis. Overall, the pooled analysis showed that pretreatment elevated platelet count was associated with poorer OS (HR= 1.47, 95%CI: 1.31-1.66, P<0.001) and poorer DFS/PFS/TTP ((HR=1.63, 95%CI: 1.28-2.09, P<0.001) in patients with lung cancer compared with normal platelet count. In subgroup analyses, pretreatment elevated platelet count was also associated with poorer OS and DFS/PFS/TTP in most subgroups. There was no evidence of publication bias.Conclusions : This meta-analysis revealed that pretreatment elevated platelet count was an independent predictor of OS and DFS/PFS/TTP in lung cancer patients. Large scale prospective studies and a validation study are warranted.

Lymphocyte To Monocyte Ratio

Background: The overall prognosis of lung cancer remains unfavorable and novel prognostic biomarkers of lung cancer are needed warranted. Accumulating evidence indicate that systemic inflammation plays a vital role in lung cancer. The lymphocyte-to-monocyte ratio (LMR) is biomarker that reflects the level of systemic inflammation. Objective: To perform a comprehensive meta-analysis exploring the correlation of pretreatment LMR with the overall survival (OS) and progression-free survival (PFS) of lung cancer patients. Methods: We conducted searches of the PubMed, Embase, Cochrane Library, and Web of Science databases to May 2020 to identify relevant studies and calculated combined hazard ratios (HRs) to evaluate the association between pretreatment LMR and survival time in patients with lung cancer. Results: A total of 23 studies comprising 8361 lung cancer patients were included. Among the patients, 5702 (68%) were males, 4548 were current smokers and 2212 were diagnosed with squamous carcinoma. The pooled analysis revealed that decreased pretreatment LMR was significantly correlated with reduced of PFS (HR = 1.49, 95% CI: 1.34-1.67, p < 0.01) and reduced OS (HR = 1.61, 95% CI: 1.45-1.79, p < 0.01) among lung cancer patients. Furthermore, in the subgroup analyses according to histologic type, a lower level of pretreatment LMR seemed to be unrelated to the poorer OS of small cell lung cancer (SCLC) patients (HR = 1.21, 95%CI: 0.87-1.67, P = 0.25). Conclusions: Decreased pretreatment LMR in peripheral blood was associated with shorter OS and PFS in lung cancer patients, suggesting its potential prognostic value.

Abstract Background:Small nucleolar RNA host gene 3 (SNHG3) is a promising long non-coding RNA that may possess prognostic value for different types of tumors. The objective of this meta-analysis is to evaluate the prognostic value of lncRNA SNHG3 in cancer patients.Methods:A systematic literature search of the PubMed, Cochrane Library, EMBASE, Medline, Web of Science, CNKI, Weipu, and Wanfang electronic databases was carried out in this meta-anaysis. The synthetic hazard ratios (HRs) or odd ratios (ORs) with 95% confidence intervals (CIs) were obtained to determine the prognostic and clinicopathological significance of SNHG3 expression in tumors. Results:The final meta-anaysis included 17 studies that contained 2072 patients. The pooled results provided evidence that SNHG3 overexpression predicted reduced overall survival (OS) (HR=2.15, 95%CI: 1.76–2.63, P<0.00001), recurrence-free survival (RFS) ( HR=2.22, 95%CI: 1.04–4.76, P=0.04) and disease-free survival (DFS) (HR=2.04, 95%CI: 1.35–3.09, P=0.0007) for various cancers. Additionally, the SNHG3 overexpression was concerned with tumor node metastasis (TNM) stage (III/IV vs. I/II, OR=2.91, 95%CI: 1.60–5.29, P=0.0005), lymph node metastasis (LNM) (positive vs negative, OR=5.00,95%CI:2.82–8.87,P＜0.00001), distant metastasis (DM) (positive vs negative, OR=2.29, 95%CI: 1.52–3.47, P<0.0001) and tumor size (larger vs smaller, OR=1.80, 95%CI: 1.04–3.11, P=0.04).Conclusions:Our results indicated that SNHG3 overexpression was closely correlated with shorter OS in multiple cancer types, suggesting that SNHG3 might function as a promising predictor for clinical outcomes in cancer.

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.

Background We investigated whether all size-based pathological T4N0–N1 non-small cell lung cancer patients with tumors at any size >7 cm had the same outcomes. Methods We reviewed non-small cell lung cancer patients with tumors >7 cm who underwent anatomical lung resection between 2010 and 2016. A total of 251 size-based T4N0–N1 patients were divided into two groups based on tumor size. Group S ( n = 192) included patients with tumors of 7.1–9.9 cm and Group L ( n = 59) as tumor size ≥10 cm. Results The mean tumor size was 8.83 ± 1.7 cm (Group S: 8.06 ± 0.6 cm, Group L: 11.3 ± 1.6 cm). There were 146 patients with pathological N0 and 105 patients with pathological N1 disease. Mean overall survival and disease-free survival were 64.2 and 51.4 months, respectively. The five-year overall survival and disease-free survival rates were 51.2% and 43.5% (five-year OS; pT4N0:52.7%, pT4N1:47.9%, DFS; pT4N0:44.3%, pT4N1: 42.3%). No significant differences were observed between T4N0 and T4N1 patients in terms of five-year OS or DFS ( p = 0.325, p = 0.505 respectively). The five-year overall survival and disease-free survival rates were 52% and 44.6% in Group S, and 48.5% and 38.9% in Group L. No significant difference was observed between the groups in terms of five-year overall survival or disease-free survival ( p = 0.699, p = 0.608, respectively). Conclusions Above 7 cm, any further increase in tumor size in non-small cell lung cancer patients had no significant effect on survival, confirming it is not necessary to further discriminate among patients with tumors in that size class.

Diagnostic Values

Circular RNAs (circRNAs) may serve as potential biomarkers for patients with lung cancer. The aim of this meta-analysis was to analyse the diagnostic, prognostic and clinicopathological values of circRNAs in lung cancer patients. A systematic search of PubMed, Embase, Web of Science, Scopus and the Cochrane Library databases was performed for relevant articles from inception to 29 January 2020. Pooled parameters including sensitivity, specificity and area under the curve (AUC) were used to assess the diagnostic performance, HRs and 95% CIs were used to evaluate overall survival (OS) and ORs were used to estimate clinicopathological parameters. 52 studies from 45 articles were enrolled in this study, including 17 on diagnosis and 35 on prognosis. For diagnostic values, circRNAs could discriminate lung cancer patients from the controls, with AUC of 0.83 (95% CI: 0.79 to 0.86), a relatively high sensitivity of 0.77 (95% CI: 0.73 to 0.81) and specificity of 0.75 (95% CI: 0.71 to 0.79). For prognostic significances, overexpression of 23 upregulated circRNAs was relevant to a poor prognosis (OS: HR=2.21, 95% CI: 1.96 to 2.49, p<0.001), and overexpression of 9 downregulated circRNAs was correlated with a favourable prognosis (OS: HR=0.62, 95% CI: 0.53 to 0.73, p<0.001). As for clinicopathological parameters, high expression of 23 upregulated circRNAs was associated with unfavourable clinicopathological features while 9 downregulated circRNAs proved the contrary. In conclusion, this study confirmed that circRNAs might serve as important biomarkers for diagnostic and prognostic values of lung cancer.

BackgroundSeveral recent publications have evaluated the prognostic value of preoperative hydronephrosis (HN) in patients with upper tract urinary carcinoma (UTUC). The aim of this meta-analysis was to explore the pooled effect of preoperative HN on the prognosis of UTUC patients treated with radical nephroureterectomy (RNU) based on current evidence.MethodsWe performed a systematic search of Pubmed, Cochrane library, and Web of Science databases from inception to June 2020. The outcomes of interest included overall survival (OS), cancer-special survival (CSS), disease-free survival (DFS), and intravesical recurrence-free survival (IVRFS).ResultsTwenty-two studies with a total of 7,542 patients satisfied the eligibility criteria and were finally included in this meta-analysis. The percent of patients with preoperative HN varied in the eligible studies, ranging from 18 to 81%. The pooled results showed that preoperative HN was significantly associated with worse OS (P = 0.004), CSS (P &lt; 0.001), and DFS (P = 0.005), but not IVRFS (P = 0.12). No obvious publication bias was detected by Begg’s test in all the analyses.ConclusionsThe results drawn in our meta-analysis suggest that the presence of preoperative HN is associated with worse prognosis in patients treated with RNU for UTUC. Therefore, closer surveillance and more aggressive therapy may be needed for UTUC patients present with preoperative HN. Well-designed prospective studies are necessary to substantiate the prognostic value of HN in UTUC.
