The minichromosome maintenance complex 3 (MCM3) is essential for the regulation of DNA replication and cell cycle progression. However, the expression and prognostic values of MCM3 in cervical cancer (CC) have not been well-studied. Herein, we investigated the expression patterns and survival data of MCM3 in cervical cancer patients from the ONCOMINE, GEPIA, Human Protein Atlas, UALCAN, Kaplan-Meier Plotter, and LinkedOmics databases. The expression level of MCM3 is negatively correlated with advanced tumor stage and metastatic status. Specifically, MCM3 is significantly differentially expressed between patients in stage 1 and stage 3 cervical cancer with p value 0.0138. Similarly, the p values between stage 1 and stage 4 cervical cancer, between stage 2 and stage 3, and between stage 2 and stage 4 are 0.00089, 0.0244, and 0.00197, respectively. Not only that, cervical cancer patients with high mRNA expression of MCM3 may indicate longer overall survival but indicate shorter relapse-free survival. PRIM2 and MCM6 are positively correlated genes of MCM3. Bioinformatics analysis revealed that MCM3 might be considered a biological indicator for prognostic evaluation of cervical cancer. However, it is currently limited to bioinformatics analysis, and more clinical tissue specimens and cell experiments are needed to further explore the role of MCM3 in the occurrence and progression of cervical cancer.

Objective: To investigate whether serum Tie-1 (sTie-1) is a valuable marker for predicting progression and prognosis of cervical cancer.Methods: Enzyme-linked immunosorbent assay (ELISA) was used to detect serum sTie-1 concentrations in 75 cervical cancer patients, 40 cervical intraepithelial neoplasia (CIN) patients, and 55 healthy controls without cervical lesions, and sTie-1 levels were compared between the groups. Receiver operating characteristic curves was used to evaluate the diagnostic value of sTie-1. The relationship between sTie-1 concentrations in patients with cervical cancer and clinicopathological features and prognosis were analyzed, and the risk factors for postoperative recurrence were determined using univariate and multivariable Cox proportional hazards regression.Results: We found that sTie-1 concentrations gradually increased according to lesion severity (i.e., cancer vs. CIN; p < 0.05) and were significantly elevated in adenocarcinoma compared with healthy controls. sTie-1 levels strongly distinguished between cervical cancer patients and the healthy controls (area under the curve = 0.846; cut-off value = 1,882.64 pg/ml; sensitivity = 74.6%; specificity = 96.4%). Moreover, sTie-1 levels in cervical cancer patients were significantly associated with tumor size, advanced tumor stage, lymph node metastasis, and reduced 4-years progression-free survival. Cervical cancer patients with high sTie-1 concentrations had a 3.123-fold [95% confidence interval (CI): 1.087–8.971, p = 0.034] higher risk for tumor recurrence.Conclusions: Elevated sTie-1 levels in patients with cervical carcinoma were associated with tumor progression and poor prognosis, indicating that sTie-1 may be a valuable marker for predicting progression and prognosis of cervical cancer.

Abstract The solute carrier 30 (SLC30) family genes play a fundamental role in various cancers. However, the diverse expression patterns, prognostic value, and potential mechanism of SLC30A family genes in gastric cancer (GC) remain unknown. Herein, we analyzed the expression and survival data of SLC30A family genes in GC patients using multiple bioinformatic approaches. Expression data of SLC30A family genes for GC patients were extracted from the Cancer Genome Atlas (TCGA) and genetic alteration frequency assessed by using cBioportal database. And validated the expression of SLC30A family genes in GC tissues and corresponding normal tissues. The prognostic value of SLC30A family genes in gastric cancer patients were explored using Kaplan–Meier plotter database. Functional enrichment analysis performed using DAVID database and clusterProfiler package. And ssGSEA algorithm was performed to explore the relationship between the SLC30A family genes and the infiltration of immune cells. We found that the median expression levels of SLC30A1-3, 5–7, and 9 were significantly upregulated in gastric cancer tissues compared to non-cancerous tissues, while SLC30A4 was downregulated. Meanwhile, SLC30A1-7, and 9 were significantly correlated with advanced tumor stage and nodal metastasis status, SLC30A5-7, and 9–10 were significantly related to the Helicobacter pylori infection status of GC patients. High expression of five genes (SLC30A1, 5–7, and 9) was significantly correlated with better overall survival (OS), first progression survival (FPS), and post progression survival (PPS). Conversely, upregulated SLC30A2-4, 8, and 10 expression was markedly associated with poor OS, FP and PPS. And SLC30A family genes were closely associated with the infiltration of immune cells. The present study implied that SLC30A5 and 7 may be potential biomarkers for predicting prognosis in GC patients, SLC30A2 and 3 play an oncogenic role in GC patients and could provide a new strategy for GC patients treatment.

AbstractThe chaperonin-containing T-complex protein 1 (CCT) subunits participate in diverse diseases. However, little is known about their expression and prognostic values in human head and neck squamous cancer (HNSC). This article aims to evaluate the effects of CCT subunits regarding their prognostic values for HNSC. We mined the transcriptional and survival data of CCTs in HNSC patients from online databases. A protein–protein interaction network was constructed and a functional enrichment analysis of target genes was performed. We observed that the mRNA expression levels of CCT1/2/3/4/5/6/7/8 were higher in HNSC tissues than in normal tissues. Survival analysis revealed that the high mRNA transcriptional levels of CCT3/4/5/6/7/8 were associated with a low overall survival. The expression levels of CCT4/7 were correlated with advanced tumor stage. And the overexpression of CCT4 was associated with higher N stage of patients. Validation of CCTs’ differential expression and prognostic values was achieved by the Human Protein Atlas and GEO datasets. Mechanistic exploration of CCT subunits by the functional enrichment analysis suggests that these genes may influence the HNSC prognosis by regulating PI3K-Akt and other pathways. This study implies that CCT3/4/6/7/8 are promising biomarkers for the prognosis of HNSC.

The long noncoding RNA, Growth arrest-specific 5 (GAS5) plays a crucial role in the development of oral cancer. However, potential genetic variants in GAS5 that affect the susceptibility and progression of oral cancer have rarely been explored. In this study, two loci of GAS5 single nucleotide polymorphisms (SNPs) (rs145204276 and rs55829688) were genotyped by using the TaqMan allelic discrimination in 1125 oral cancer patients and 1195 non-oral-cancer individuals. After statistical analyses, the distribution of both the GAS5 SNP rs145204276 and GAS5 SNP rs55829688 frequencies were similar between the study and control groups. However, the patients with GAS5 SNP rs145204276 variants (Ins/Del or Del/Del) showed a higher tendency of moderate to poor cell differentiation of oral cancer (OR: 1.454, 95% CI: 1.041–2.031, p = 0.028). Moreover, the GAS5 SNP rs145204276 variants (Ins/Del or Del/Del) in the non-alcohol-drinking population were associated with significantly advanced tumor stage (OR: 1.500, 95% CI: 1.081–2.081, p = 0.015) and larger tumor size (OR: 1.494, 95% CI: 1.076–2.074, p = 0.016). Furthermore, individuals with the GAS5 SNP rs145204276 variant were associated with a higher expression of GAS5 in the GTEx database (p = 0.002), and the higher GAS5 level was associated with poor cell differentiation, advanced tumor stage and larger tumor size in head and neck squamous cell carcinoma from the TCGA database (all p < 0.05). In conclusion, the GAS5 SNP rs145204276 variant is related to poor-differentiation cell status in oral cancer. Besides, the presence of the GAS5 SNP rs145204276 variant is associated with a worse tumor stage and tumor size in oral cancer patients without alcohol drinking.

Angiopoietin 1

Objectives Angiopoietins have been found to play essential roles in tumor angiogenesis. The present study was aimed at investigating the diagnostic and prognostic values of serum angiopoietin 1 and 2 (sAng-1 and sAng-2) in cervical cancer. Methods The sAng-1 and sAng-2 concentrations were analyzed in 77 women with cervical cancer, 44 women with cervical intraepithelial neoplasia (CIN) and 43 women without cervical lesions by enzyme-linked immunosorbent assay. The diagnostic values of sAng-1, sAng-2 and sAng-1/sAng-2 were evaluated by receiver operating characteristic (ROC) curves. The Ang-1 and Ang-2 expression in cervical cancer tissues as well as microvessel density (MVD), were assessed by immunohistochemistry. Results The concentration of sAng-2 gradually increased and the sAng-1/Ang-2 ratio was gradually decreased from normal control to CIN, then to squamous cell cancer, and the sAng-1/sAng-2 ratio was also significantly decreased in adenocarcinoma. The area under ROC curves of sAng-2 and sAng-1/sAng-2 ratio for discriminating cervical cancer from normal were 0.744 and 0.705, respectively. Decreased sAng-1/sAng-2 was significantly associated with advanced tumor stage, poor differentiation, lymph-vascular space invasion and high MVD. sAng-2 was positively correlated with the Ang-2 expression in cervix epithelia. A high sAng-1/sAng-2 ratio was associated with a longer progression-free survival and a longer overall survival in cervical cancer patients. Conclusions These findings suggest that sAng-2 and the sAng-1/sAng-2 ratio may be valuable diagnostic and prognostic biomarkers for cervical cancer.

Background/Aims: Emerging studies have shown that the neutrophil-lymphocyte ratio (NLR) is a potential predictor in various tumors. Our study was conducted to assess the prognostic value of the pretreatment NLR in bladder cancer and metastatic or unresectable urothelial carcinoma (mUC or uUC) patients up to July 2017. The correlation between the pretreatment NLR and pathological characteristics was also evaluated in bladder cancer patients. Methods: The hazard ratio (HR) and odds ratio (OR) with the 95% confidence interval (CI) were extracted or calculated from the included studies for further pooled analysis. A total of 21 studies were included in a pooled analysis. Results: The pooled results indicated that a high pretreatment NLR was associated with reduced overall survival (OS) (HR=1.27, 95% CI=1.12-1.43), relapse-free survival (RFS) (HR=1.41, 95% CI=1.23-1.60), progression-free survival (PFS) (HR=1.75, 95% CI=1.36-2.15), disease-specific survival (DSS) and cancer-specific survival (CSS) (HR=1.27, 95% CI=1.19-1.35) in the bladder cancer patients. Additionally, an elevated pretreatment NLR suggested a worse OS rate in the mUC or uUC patients (HR=1.63, 95% CI=1.34-1.91). The pooled ORs and 95% CIs showed that a high pretreatment NLR could be a risk indicator for certain pathological features, such as lymphovascular invasion, a positive margin status and advanced tumor stage. Conclusions: our results showed that a high pretreatment NLR predicted poor prognosis in bladder cancer, mUC and uUC patients.

e15110 Background: Risk factors for the pancreatic cancer are cigarette smoking, obesity, family history, chronic pancreatitis and type 2 diabetes mellitus. Diabetes mellitus is associated with 2-3 fold increase in the risk of pancreas cancer development. Down-regulation of mTOR pathway which begins with the insulin signaling is the possible protective effect of metformin in the oncogenesis of pancreatic cancer. In this study, we aimed to evaluate whether the use of metformin in diabetic pancreas cancer patients has an advantage or not. Methods: The data of 467 patients with the diagnosis of pancreas cancer in from 2003 to 2012 were analyzed, retrospectively. Results: Four hundred and sixty seven patients with the median age of 62 (20-85) were reviewed Median tumour size was 42 mm (14-145 mm). According to 2010 TNM staging, 23 patients had stage 1 (4.9%), 97 patients stage 2 (20.8%), 70 patients stage 3 (15%) and 277 patients had stage 4 disease (59.3%). Diabetes mellitus was detected in 173 (37%) patients. In this group 23 patients had stage 1 (4.9%), 97 patients stage 2 (20.8%), 70 patients stage 3 (15%) and 98 patients had stage 4 disease (56.6%). Thirty seven percent (64 patients) of the patients with diabetes were using metformin. Median time for metformin usage was 14±2,3 months. Median follow-up time was 7 months (1-88 months). Median overall survival (OS) of all pancreas cancer patients was 8 months. Surprisingly, median OS of diabetic pancreas cancer patients and non-diabetics was 9 and 8 months, respectively (statistically not significant). Median OS of diabetic patient subgroup who use metformin or not was 7 versus 10 months, respectively (statistically not significant). In the subgroup of stage 3 pancreatic cancer patients with diabetes mellitus, the median OS were 16 months and 10 months according to metformin usage or not, respectively (p=02). Conclusions: In this study, the median OS of diabetic pancreas cancer patients was superior from the non-diabetics. Multi-center prospective trials including large number of patients are needed to understand well enough the benefit of metformin in diabetic pancreas carcinoma patients.

Background. The objective of our study is to investigate the potential effect of adjusting preoperative platelet to lymphocyte ratio, an emerging biomarker of survival in cancer patients, for the fraction of large platelets.Methods. A total of 79 patients with breast neoplasias, 44 with fibroadenomas, and 35 with invasive ductal carcinoma were included in the study. Both conventional platelet to lymphocyte ratio (PLR) and the adjusted marker, large platelet to lymphocyte ratio (LPLR), were correlated with laboratory and histopathological parameters of the study sample.Results. LPLR elevation was significantly correlated with the presence of malignancy, advanced tumor stage, metastatic spread in the axillary nodes and HER2/neu overexpression, while PLR was only correlated with the number of infiltrated lymph nodes.Conclusions. This is the first study evaluating the effect of adjustment for large platelet count on improving PLR accuracy, when correlated with the basic independent markers of survival in a sample of breast cancer patients. Further studies are needed in order to assess the possibility of applying our adjustment as standard in terms of predicting survival rates in cancer.

282 Background: Death within 1 month of surgery is considered treatment related and serves as an important healthcare quality metric. We sought to identify the incidence of and factors associated with 1-month mortality after cancer-directed surgery. Methods: We used the Surveillance, Epidemiology and End Results Program to study a cohort of 1,110,236 patients diagnosed from 2004-2011 with cancers that are among the 10 most common or most fatal who received cancer-directed surgery. Multivariable logistic regression analyses were used to identify factors associated with 1-month mortality after cancer-directed surgery. Results: 53,498 patients (4.8%) died within 1 month of cancer-directed surgery. Patients who were married, insured, or who had a top 50th percentile income or educational status had lower odds of 1-month mortality from cancer-directed surgery ([adjusted odds ratio (AOR) 0.80; 95% CI 0.79 – 0.82; P<0.001], [AOR 0.88; (0.82 – 0.94); P<0.001], [AOR 0.95; (0.93 – 0.97); P<0.001], and [AOR 0.98; (0.96 – 0.99); P=0.043], respectively). Patients who were non-white minority, male, or older (per year increase), or who had advanced tumor stage 4 disease all had a higher risk of 1-month mortality after cancer-directed surgery, with AORs of 1.13 (1.11 – 1.15), P<0.001; 1.11 (1.08 – 1.13), P<0.001; 1.02 (1.02 – 1.03), P<0.001; and 1.89 (1.82 – 1.95), P<0.001 respectively. Conclusions: Unmarried, uninsured, non-white, male, older, less educated, and poorer patients were all at a significantly higher risk for death within 1 month of cancer-directed surgery. Efforts to reduce 1-month surgical mortality and eliminate sociodemographic disparities in this adverse outcome could significantly improve survival among patients with cancer.
