e14595 Background: MIC1 and MMP7 are secreted cytokines involved respectively in the modulation of immunological processes and in extracellular matrix remodeling. Their expression were found deregulated in different tumors, including GC. However, few data are available about their serum levels, their diagnostic potential, and their prognostic significance in GC pts. Here, we analyze the diagnostic performance of these markers and we present data linking them with short survival in GC pts. Methods: Serum samples were assayed in duplicate for MIC1 and MMP7 levels by ELISA. The diagnostic performance of markers was assessed by ROC curve analysis and the cut-offs were set using the Youden index approach. The cut-offs for prognostic purposes were determined using X-tile software. Differences in progression free (PFS) and overall survival (OS) were analyzed using Kaplan-Meier curves and logrank test. Cox regression was used to determine the prognostic independence of biomarkers. Results: From November 2006 to July 2010, 52 GC pts and 28 healthy donors were consecutively recruited. The follow-up of pts was performed until their death or the end of study (September 2011). The AUCs for MIC1 and MMP7 were respectively 0.897 and 0.865 (p < 0.001). Using the optimal cut-off to diagnose GC pts, we obtained a 73.08% of sensitivity (Ss) and a 92.86% of specificity (Sp) for MIC1, and a 78.85% of Ss and an 85.71% of Sp for MMP7. In the survival analysis, high serum levels of MIC1 and MMP7 were significantly associated with shorter PFS (p < 0.001) and OS (p < 0.001 and p = 0.003, respectively). In univariate analysis, pts with high serum levels of MIC1 and MMP7 had an increased risk of progression (HR = 3.608, p<0.001 for MIC1; HR = 4.172, p<0.001 for MMP7) and death (HR = 3.843, p=0.001 for MIC1; HR = 2.602, p=0.006 for MMP7). However, MIC1 and MMP7 failed to reach prognostic independence in multivariate analysis. Conclusions: We obtained cut-off values of MIC1 and MMP7 in serum for diagnostic purposes in GC. In addition, we established a correlation between increased levels of MIC1 and MMP7 in serum and shorter PFS and OS in GC. These findings justify studies with a larger number of pts.

ObjectiveThe relationship between serum levels of calcium, parathyroid hormone (PTH) and risk of venous thromboembolism (VTE) has not been addressed in population-based cohorts. We investigated the associations between serum levels of calcium and PTH, with future risk of VTE in a general adult population.DesignPopulation-based cohort.MethodsA total of 27 712 subjects (25–87 years) who participated in Tromsø 4 (1994–1995) and Tromsø 5 (2001–2002) surveys were included in the study, and total calcium and PTH were measured in 27 685 and 8547 subjects respectively. Incident VTE was recorded through December 31, 2012. Cox-regression models with calcium and PTH as time-varying exposures were used to calculate hazard ratios (HR) of VTE by quartiles of calcium and PTH. Quartiles of calcium and PTH were also combined to assess the effect of discordants of both PTH and calcium (e.g. highest and lowest quartiles of both calcium and PTH) on VTE risk using the middle two quartiles as reference.ResultsThere were 712 VTEs during 15.0 years of median follow-up. Serum levels of calcium and PTH were not associated with risk of VTE. However, subjects with discordant high serum levels of both calcium and PTH (calcium ≥2.45 mmol/L and PTH ≥4.0 pmol/L) had increased risk of VTE compared to those in subjects with normal calcium and PTH (multivariable HR: 1.78, 95% CI: 1.12–2.84).ConclusionsSerum levels of calcium and PTH separately were not associated with future risk of VTE, but subjects with high levels of both calcium and PTH had increased risk of VTE compared to those in subjects with normal levels.

Background/Aims: The prognostic role of serum procalcitonin level in critically ill patients with ventilator-associated pneumonia was unclear. The aim of our study was to investigate the relationship between serum procalcitonin level and mortality risk in critically ill patients with ventilator-associated pneumonia. Methods: Data of critically ill patients with ventilator-associated pneumonia were retrospectively collected. Demographics, comorbidities, and serum procalcitonin level were extracted from electronic medical records. The primary outcome was mortality within two months after diagnosis. Multivariable Cox regression analyses were performed to assess the prognostic role of serum procalcitonin level in those patients. Results: A total of 115 critically ill patients with ventilator-associated pneumonia were enrolled in our study. Serum procalcitonin level was not associated with age, gender, or other comorbidities. Univariate Cox regression model showed that high serum procalcitonin level was associated increased risk of morality within 2 months after diagnosis (OR = 2.32, 95% CI 1.25-4.31, P = 0.008). Multivariable Cox regression model showed that high serum procalcitonin level was independently associated increased risk of morality within 2 months after diagnosis (OR = 2.38, 95% CI 1.26-4.50, P = 0.008). Conclusion: High serum procalcitonin level is an independent prognostic biomarker of mortality risk in critically ill patients with ventilator-associated pneumonia, and it's a promising biomarker of prognosis in critically ill patients.

Central Pulse Pressure

Higher central pulse pressure is associated with higher carotid-femoral pulse wave velocity (CFPWV) and an increased risk of cardiovascular disease (CVD). A smaller aortic root diameter (AoR) is associated with higher central pulse pressure. We hypothesized that the combination of a smaller AoR and higher CFPWV is associated with increased CVD risk (relative to a larger AoR and lower CFPWV). We tested this hypothesis in the community-based Framingham Study (N=1970, mean age 60 years, 57% women). We created sex-specific longitudinal echocardiographic AoR trajectories over 2 decades, categorizing participants into smaller versus larger AoR groups. We cross-classified participants based on their AoR trajectory and CFPWV (dichotomized at the sex-specific median). We used Cox regression to relate the cross-classified groups to CVD incidence on follow-up (median 17 years): lower CFPWV, larger AoR (referent group; 6.4/1000 person-years); lower CFPWV, smaller AoR (6.9/1000 person-years); higher CFPWV, larger AoR (23.1/1000 person-years); and higher CFPWV, smaller AoR (21.9/1000 person-years). In sex-pooled analyses, groups with higher CFPWV were associated with a multivariable-adjusted 1.8-fold risk of CVD ( P <0.01) regardless of AoR size. We observed effect modification by sex ( P for sex×AoR-CFPWV group interaction 0.04). In men, the group with smaller AoR and higher CFPWV was associated with a 2.5- to 2.8-fold risk of CVD ( P <0.001). In women, the group with larger AoR and higher CFPWV experienced a statistically nonsignificant 70% to 80% higher CVD risk. Our observations indicate that the prognostic significance of a smaller versus larger AoR varies in men versus women. Additional studies are warranted to confirm our findings.

Abstract Background Studies have shown that inflammation-associated blood cell markers are associated with prognoses in a variety of tumors. However, the prognostic significance of these markers for gastric cancer (GC) is still not very clear. This article aims to explore its value of GC prognostic assessment.Methods From July 2011 to July 2016, 353 GC patients with surgical treatment were enrolled in this retrospective study. Patients’ demographics were analyzed along with clinical and pathologic data. The chi-square test was used to evaluate relationships between the markers and other clinicopathological variables; The Kaplan–Meier method and Cox regression proportional hazard model were performed to evaluate prognostic factors.Results Univariate analysis indicated T stage, N stage, vascular tumor thrombus, tumor long diameter, Bormann Classification, preoperative MWR (monocyte/leukocyte ratio), preoperative serum CEA levels are prognostic factors for GC. Multivariate analysis showed that preoperative MWR, tumor differentiation, and tumor length were independent prognostic factors in patients with GC. The boundary value of MWR is 0.8.Conclusion Preoperative MWR was convenient, simple marker of gastric cancer, might be useful for the evaluation of prognosis of patients with GC. Comparing with TNM stage, tumor differentiation was a more reliable pathological factor evaluating recurrence.

Many studies have reported the prognostic significance of peak oxygen consumption (VO 2 ) and V E -VCO 2 slope in patients with heart failure (HF). However, there are limited data stratifying risk based on a combination of these measures and how to best use them. Purpose: Describe 1 and 3-y event rates for the composite endpoint of mortality, left ventricular assist device (LVAD), or cardiac transplant (CT) based on the combined evaluation of peak VO 2 and V E -VCO 2 slope in patients with HF with reduced ejection fraction (≤ 40%; HFrEF). Methods: Patients (n= 1,116; 33% female; age= 54 ± 13 y) with a cardiopulmonary exercise test between 1997 and 2010 and confirmed HFrEF were identified. Endpoint data was obtained through 2011. Patients were grouped based on peak VO 2 (< 12, 12 to18, and > 18 mL/kg/min) and (V E -VCO 2 slope ≥ 34 or < 34). Cumulative events were identified from life tables. Cox regression with adjustment for age, gender, ejection fraction, and beta-blocker therapy was used to calculate the hazard ratio for V E -VCO 2 slope ≥ 34 within each peak VO 2 group. Results: The 1 and 3-y event rates are shown in the Table. Among patients with a peak VO 2 < 12, 1 and 3-y events were 23% and 44%, respectively. Within this group, V E -VCO 2 slope ≥ 34 represented more than twice the risk at both 1 y (HR 2.42, 95% CI 1.09, 5.38) and 3 y (HR 2.32, 95% CI 1.33, 4.05). Among patients with a peak VO 2 12 to 18, 1 and 3-y events were 14% and 30%, respectively. Within this group, a V E -VCO 2 slope ≥ 34 was associated with increased risk at both 1 y (HR 1.80, 95% CI 1.13, 2.87) and 3 y (HR 1.80, 95% CI 1.30, 2.50). Among patients with peak VO 2 > 18, 1 and 3-y events were 2% and 10%, respectively, and V E -VCO 2 slope was not statistically associated with increased risk. Conclusion: Among patients with a peak VO 2 ≤ 18, V E -VCO 2 slope ≥ 34 further refines the risk for a composite endpoint of mortality, LVAD, or CT at both 1 and 3 y.

Galectin 3

PURPOSE: Galectin-3 is a pleiotropic carbohydrate-binding protein participating in a variety of normal and pathologic processes, including cancer progression. This study was aimed at evaluating the prognostic value of galectin-3 expression in node-negative laryngeal squamous-cell carcinoma (SCC). PATIENTS AND METHODS: Galectin-3 expression was analyzed by immunohistochemistry using M3/38 monoclonal antibody, in a single-institution series of 73 node-negative laryngeal SCC patients (median follow-up, 52 months; range, 2 to 90 months). RESULTS: Forty-two (57.5%) of 73 patients expressed galectin-3. Galectin-3 expression was positively associated with tumor keratinization and histologic grade. A significant correlation was found between galectin-3 tumor positivity and longer relapse-free and overall survival. In univariate analysis, high-grade (grade 3 or 4) tumors, nonkeratinizing tumors, and galectin-3–negative tumors showed a significantly increased risk of relapse and death. In multivariate analysis, only galectin-3 expression retained an independent prognostic significance for both relapse-free and overall survival. CONCLUSION: We conclude that the absence of galectin-3 expression is an independent negative prognostic marker in laryngeal SCC patients. Thus, histochemical detection of galectin-3 in these tumors could be useful for the selection of node-negative patients with potentially unfavorable outcomes, to establish adjuvant therapy protocols.

OBJECTIVES/SPECIFIC AIMS: Our objective was to examine serum E2 levels in dcSSc males in relation to disease characteristics (i.e autoanitbody profile and internal organ involvement) and its impact on survival. METHODS/STUDY POPULATION: We measured serum E2 levels in 83 dcSSc men >50 years old from the University of Pittsburgh Scleroderma Center and healthy controls of similar age. Using statistical modeling, we examined the associations between circulating E2 levels, internal organ involvement, autoantibody profiles, and survival. RESULTS/ANTICIPATED RESULTS: Male dcSSc patients had significantly higher serum E2 levels compared to healthy male controls and compared to dcSSc post-menopausal women of similar age. Male dcSSc patients with high serum E2 levels had significantly more heart involvement and worse survival. Using Cox regression modeling for risk of death, increasing serum E2 levels in anti-Scl-70 antibody positive dcSSc males were associated an increased risk of death. DISCUSSION/SIGNIFICANCE OF IMPACT: DcSSc male patients have higher levels of E2 compared to healthy controls and dcSSc postmenopausal women. Elevated serum E2 levels in dcSSc males >50 are associated with heart involvement and, if anti-Scl-70 antibody positive, worse survival. Our current study expands on our previous work, not only that that E2 exerts pro-fibrotic effects on skin, but also internal organ involvement, overall survival. These data suggest an important role of estrogen imbalance in SSc.

ObjectivePrevious studies have postulated a causal role of patent foramen ovale (PFO) in the aetiology of embolic stroke in the general population. We hypothesised that the presence of concomitant PFO and atrial fibrillation (AF) will add incremental risk of ischaemic stroke to that linked to AF alone.MethodsWe analysed data on 3069 consecutive patients (mean age 69.4±12.2 years; 67.1% men) undergoing transoesophageal echocardiography-guided electrical cardioversion (ECV) for AF between May 2000 and March 2012. PFO was identified by colour Doppler and agitated saline contrast study. All patients were followed up after ECV for first documentation of ischaemic stroke. Outcomes were compared using Cox regression models.ResultsThe prevalence of PFO was 20.0% and the shunt direction was left-to-right in the majority of patients (71.4%). Patients with PFO had a higher frequency of obstructive sleep apnoea (21.7% vs 17.1%, p=0.01) and higher mean peak left atrial appendage emptying velocity (38.3±21.8 vs 36.1±20.4 cm/s; p=0.04) compared with those without PFO. Otherwise, baseline characteristics were similar between groups. During a mean follow-up period of 7.3±4.6 years, 214 patients (7.0%) had ischaemic stroke. Multivariable analysis showed no significant association between PFO and ischaemic stroke (HR, 0.82 (95% CI 0.57 to 1.18)). PFO shunt direction was strongly associated with stroke: HR, 1.91 (95% CI 1.16 to 3.16) for right-to-left shunt and HR, 0.58 (95% CI 0.36 to 0.93) for left-to-right shunt.ConclusionsThe presence of concurrent PFO in this largely anticoagulated group of patients with AF was not associated with increased risk of ischaemic stroke.

This study aimed to evaluate the association between abdominal-to-gluteofemoral adipose tissue (AT) distribution and recurrence-free survival (RFS) in breast cancer patients. Staging F-18 fluorodexoyglucose (FDG) positron emission tomography/computed tomography (PET/CT) images of 336 women with breast cancer were retrospectively analyzed. From CT images, the volume and CT-attenuation of visceral adipose tissue (VAT), abdominal subcutaneous adipose tissue (SAT), and gluteofemoral AT were measured and the ratio of abdomen-to-gluteofemoral AT volume (AG volume ratio) was calculated. The relationships between adipose tissue parameters and RFS were assessed. Through univariate analysis, abdominal SAT volume, gluteofemoral AT volume, and AG volume ratio were significantly associated with RFS. An increase in abdominal SAT volume and AG volume ratio were associated with an increased risk of recurrence, whereas increased gluteofemoral AT volume was associated with a decreased risk of recurrence. On multivariate analysis, abdominal SAT volume, gluteofemoral AT volume, and AG volume ratio were found to be significant predictors of RFS after adjusting for clinic-histological factors. Irrespective of obesity, patients with a high AG volume ratio showed a higher recurrence rate than those with a low AG volume ratio. Increased abdominal SAT volume and decreased gluteofemoral AT volume were related to poor RFS in breast cancer patients.

BackgroundLung cancer is the most incident and lethal form of cancer, with late diagnosis as a major determinant of its bad prognosis. Immunotherapies targeting immune checkpoints improve survival, but positive results encompass only 30%–40% of the patients, possibly due to alternative pathways to immunosuppression, including tumour-associated macrophages (TAM). Colony stimulating factor-1 (CSF-1) is implicated in TAM differentiation and recruitment to tumours and in tumour angiogenesis, through a special setting of Tie-2-expressing macrophages, which respond to angiopoietin-2 (Ang-2). We evaluated the role of serum levels of CSF-1 in non-small cell lung cancer (NSCLC) prognosis and whether these could serve as biomarkers for NSCLC detection, along with Ang-2.Participants and methodsWe prospectively studied an unselected cohort of 145 patients with NSCLC and a group of 30 control individuals. Serum levels of Ang-2 and CSF-1 were measured by ELISA prior to treatment.ResultsSerum levels of CSF-1 and Ang-2 are positively correlated (p<0.000001). Individuals with high serum levels of CSF-1 have a 17-fold risk for NSCLC presence and patients with combined High Ang-2/CSF-1 serum levels present a 5-fold increased risk of having NSCLC. High Ang-2/CSF-1 phenotype is also associated with worst prognosis in NSCLC.ConclusionsCombined expression of CSF-1 and Ang-2 seems to contribute to worst prognosis in NSCLC and it is worthy to understand the basis of this unexplored partnership. Moreover, we think CSF-1 could be included as a biomarker in NSCLC screening protocols that can improve the positive predictive value of the current screening modalities, increase overall cost effectiveness and potentially improve lung cancer survival.
