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.

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.

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.

Background MicroRNAs have been implicated in many biological pathways involved in tumourigenesis and can serve as prognostic biomarkers in many cancer types. The present study aims at evaluating the prognostic significance of miR-425-5p in cervical cancer. Methods Real-time polymerase chain reaction was performed to assess the expression levels of miR-425-5p in 35 pairs of cervical cancer tissues and their matched normal tissues as well as serum samples from 40 cervical cancer patients, 13 benign cervical disease patients and 32 healthy controls. The association between miR-425-5p expression levels in tissue and serum, and clinicopathological factors was examined. The correlation between serum miR-425-5p expression levels and overall survival of cervical cancer patients was assessed by Kaplan–Meier analysis and Cox proportional hazards model. Results MiR-425-5p expression levels were significantly increased in cervical cancer tissues compared with matched non-cancerous tissues. Higher expression of miR-425-5p was positively associated with high tumour stage ( P = 0.0003) and positive lymph node metastasis ( P = 0.0107). Serum concentrations of miR-425-5p in cervical cancer patients were significantly higher compared with benign cervical disease and healthy controls. Moreover, the up-regulation of serum miR-425-5p occurred more frequently in cervical cancer patients with high TNM stage ( P = 0.0003) and positive lymph node metastasis ( P = 0.0037). Kaplan–Meier analysis showed that high serum miR-425-5p expression levels predicted poor survival ( P = 0.0571). Cox proportional hazards risk analysis demonstrated that miR-425-5p was an independent prognostic factor for cervical cancer. Conclusion Our study suggests that miR-425-5p is up-regulated in cervical cancer and serum miR-425-5p may serve as a potential prognostic biomarker for cervical cancer.

ObjectiveThe aim of this study was to investigate the prevalence and prognostic significance of an elevated platelet count at the time of the initial diagnosis in patients with cervical cancer who are treated with definitive radiotherapy.MethodsThe baseline characteristics and outcome data of cervical cancer patients who were treated with definitive radiotherapy between November 1993 and December 2011 were collected and retrospectively reviewed. The patients were separated into 2 groups according to their platelet counts. The clinicopathological characteristics and overall survival rates of the 2 groups were compared. A Cox proportional hazards regression model was used to investigate the prognostic significance of an elevated platelet count.ResultsAn elevated platelet count was found to be associated with younger age (P = 0.0003), an advanced clinical stage (P < 0.0001), larger tumors (P = 0.0025), lower hemoglobin levels (P < 0.0001), and more frequent treatment failure (P = 0.0015). Multivariate analysis demonstrated that an advanced clinical stage (hazards ratio [HR], 2.93; 95% confidence interval [CI], 1.47–6.70; P = 0.0015), nonsquamous cell carcinoma histology (HR, 2.67; 95% CI, 1.52–4.42; P = 0.0011), larger tumors (HR, 3.86; 95% CI, 2.18–7.03; P < 0.0001), lower hemoglobin levels (HR, 1.99; 95% CI, 1.34–2.93; P = 0.0008), and an elevated platelet count (HR, 1.65; 95% CI, 1.03–2.56; P = 0.0395) were significant predictors of survival.ConclusionsAn elevated platelet count at the time of the initial diagnosis is an independent prognostic factor in cervical cancer patients who are treated with definitive radiotherapy.

16034 Background: We have previously reported on the incidence of thromboembolic events (TE) in cervical cancer patients treated with definitive chemoradiation.Patients with TE seemed to have decreased survival compared to those without TE. We reviewed a larger cohort to compare the survival of cervical cancer patients with and without TE. Materials and Methods: We performed a retrospective chart review of cervical cancer patients diagnosed and treated at the University for Iowa from January 1997 until December 2003. Data sources included the University of Iowa Tumor Registry, the Gynecologic Oncology Tumor Data Base, and the relevant ICD-9 codes to identify cervical carcinoma and types of TE in both inpatients and outpatients. Statistical analysis included the Pearson chi-squared test for categorical variable, and the two-sample t-test for continuous factors. Log-rank tests were used for survival analysis along with the generation of Kaplan-Meier survival curves. Multivariate analysis was performed with Cox proportional hazards regression. All tests are two sided and carried out at the 5% level of significance. Results: Three hundred and fifty nine (359) patients were treated with surgery or chemoradiation; thirty-six patients (10%) developed TE. There were significant associations between thromboembolic status and pelvic irradiation (p=0.0493), chemotherapy (p=0.0118), and stage (p=0.0197). Survival could not be estimated for patients not experiencing a thromboembolism; survival did not drop below 50% by the end of follow-up. Median survival time for patients with thromboembolism was 4.5 years. According to log-rank test, this difference was significant (p-value<0.0001). Conclusion: The incidence of thromboembolic events in this cohort of cervical cancer patients was 10%. TE was associated with a significant decrease in survival. No significant financial relationships to disclose.

353 Background: High rates of recurrence following surgery (S) for intrahepatic cholangiocarcinoma (ICC) have prompted treatment strategies that incorporate chemotherapy (CT). However the benefit of CT remains poorly defined. The present study sought to determine the survival impact of CT for surgically resected ICC. Methods: Patients with non-metastatic ICC that underwent curative intent surgery (R0) were identified from the National Cancer Database (1998-2011) and stratified by receipt of CT. Log rank tests and cox proportional hazards models were used to examine overall survival (OS). Results: A total of 1,729 patients were identified (median age: 66 years, 53% female); 520 (30.1%) received CT. Patients receiving CT were younger (61 vs 66 years, p<0.01), had larger tumors (>5cm: 47 vs 40%, p<0.01), and had a higher frequency of lymph node metastasis (23 vs 12%, p<0.01). However, lymph node evaluation was not conducted in 30% (n=519) of the collective cohort. In the entire series, there was no difference in unadjusted median OS between patients receiving CT compared to S alone (30 vs 32 months, p=0.31). In multivariate models, advanced tumor stage and lymph node status (p<0.05) were associated with shorter OS. When stratified by lymph node status, CT demonstrated a significant improvement in median OS among N1 patients (HR: 0.47, 95%CI: 0.25-0.87; p=0.02). In contrast, patients with N0 disease derived no benefit from CT (HR: 0.95, 95%CI: 0.65-1.39; p=0.80). Conclusions: The use of CT was associated with a survival benefit only for ICC patients with nodal metastasis. Assessment of lymph nodes at the time of surgical resection is critical when attempting to identify a subgroup of patients best suited for CT.

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.

There have been no studies as to whether parthanatos, a poly (adenosine diphosphate-ribose) polymerase-1 (PARP-1)-dependent and apoptosis-inducing factor (AIF)-mediated caspase-independent programmed cell death, is present in pulmonary hypertension (PH). Basic studies have, however, been conducted on several of the key molecules in parthanatos, such as PARP-1, AIF, and macrophage migration inhibitory factor (MIF). For this study, we collected blood samples from 88 incident male patients with PH and 50 healthy controls at the Shanghai Pulmonary Hospital. We measured the key factors of parthanatos (PARP-1, PAR, AIF, and MIF) by enzyme-linked immunosorbent assay and performed a logistic regression, Cox proportional hazards analysis, and Kaplan–Meier test to assess the prognostic value of the key molecules in diagnosing and predicting survival. The patients who ultimately died had a significantly poorer clinical status during the study than those who survived. The PARP-1, PAR, AIF, and MIF levels were significantly higher in the patients than in the controls (all p < .0001), and the PARP-1, PAR, and AIF levels were higher in the nonsurvivors than in the survivors (all p < .0001). PARP-1 and AIF levels served as independent predictors of disease onset and mortality in these patients (all p < .005). Patients with PARP-1 levels <11.24 ng/mL or AIF levels <1.459 pg/mL had significantly better survival than those with higher PARP-1 or AIF levels ( p < .0001). Circulating levels of PARP-1 and AIF were independent predictors for PH onset and mortality, which indicated that parthanatos might be associated with the pathogenesis of PH.

Abstract Background We aimed to determine whether Plasmodium falciparum (Pf) infection affects age of Kaposi sarcoma-associated herpesvirus (KSHV) seroconversion in Kenyan children. Methods Kenyan children (n=144) enrolled at age one month, from two sites with different levels of malaria transmission (stable/high malaria vs. unstable/low malaria transmission) were followed through 24 months. Plasma was tested for KSHV antibodies using enzyme-linked immunosorbent assay (ELISA) (K8.1 and LANA) and a multiplex bead-based assay (K8.1, K10.5, ORF38, ORF50, and LANA) and whole blood tested for Pf DNA using quantitative-PCR. Cox proportional hazards models were used to assess associations between Pf DNA detection, malaria annualized rate (Pf detections/person-years), and enrollment site (malaria-high vs malaria-low) with time to KSHV seroconversion. Results KSHV seroprevalence was 63% by 2 years of age when assessed by multiplex assay. Children with Pf were at increased hazards of earlier KSHV seroconversion and among children with malaria, the hazard of becoming KSHV seropositive increased significantly with increasing malaria annualized rate. Children from the malaria-high transmission region had no significant difference in hazards of KSHV seroconversion at 12 months but were more likely to become KSHV seropositive by 24 months of age. Discussion Malaria exposure increases the risk for KSHV seroconversion early in life.

ObjectivesTo investigate the safety and outcomes of elective para-aortic (PA) nodal irradiation utilizing modern treatment techniques for patients with node positive cervical cancer.MethodsPatients with pelvic lymph node positive cervical cancer who received radiation were included. All patients received radiation therapy (RT) to either a traditional pelvic field or an extended field to electively cover the PA nodes. Factors associated with survival were identified using a Cox proportional hazards model, and toxicities between groups were compared with a chi-square test.Results96 patients were identified with a mean follow up of 40 months. The incidence of acute grade ≥ 2 toxicity was 31% in the elective PA nodal RT group and 15% in the pelvic field group (Chi-square p = 0.067. There was no significant difference in rates of grade ≥ 3 acute or late toxicities between the two groups (p&gt;0.05). The KM estimated 5-year OS was not statistically different for those receiving elective PA nodal irradiation compared to a pelvic only field, 54% vs. 73% respectively (log-rank p = 0.11).ConclusionsElective PA nodal RT can safely be delivered utilizing modern planning techniques without a significant increase in severe (grade ≥ 3) acute or late toxicities, at the cost of a possible small increase in non-severe (grade 2) acute toxicities. In this series there was no survival benefit observed with the receipt of elective PA nodal RT, however, this benefit may have been obscured by the higher risk features of this population. While prospective randomized trials utilizing a risk adapted approach to elective PA nodal coverage are the only way to fully evaluate the benefit of elective PA nodal coverage, these trials are unlikely to be performed and instead we must rely on interpretation of results of risk adapted approaches like those used in ongoing clinical trials and retrospective data.
