Abstract Background: Soluble urokinase plasminogen activator receptor (suPAR) levels have previously been associated with readmission and mortality in acute medical patients in the ED. However, no specific cut-offs for suPAR has been tested in this population. Methods: Prospective observational study of acute medical patients. Follow-up of mortality and readmission was carried out for 30- and 90 days stratified into baseline suPAR < 4, 4-6 and > 6 ng/ml. suPAR levels were measured using suPARnostic® Turbilatex assay on a Cobas c501 (Roche Diagnostics Ltd) analyser. Results: A total of 1747 acute medical patients in the ED were included. Median age was 70 (IQR: 57-79) and 51.4% were men. Cox regression analysis showed that suPAR, independently of age, sex and C-reactive protein levels, predicted 30- and 90-day mortality (both p<0.001). Among patients with suPAR below 4 ng/ml (N=804, 46.0%), 8 (1.0%) died within 90-day follow-up, resulting in a negative predictive value of 99.0% and a sensitivity of 94.6%. Altogether 514 (29.4%) patients had suPAR4-6 ng/ml, of whom 43 (8.4%) died during 90-day follow-up. Among patients with suPAR above 6 ng/ml (N=429, 24.6%), 87 patients (20.3%) died within 90-day follow-up, resulting in a positive predictive value of 20.1% and a specificity of 78.7%. Conclusions: suPAR cut-offs of below 4, between 4-6 and above 6 ng/ml can identify acute medical patients who have low, medium or high risk of 30- and 90-day mortality. The turbidimetric assay provides fast suPAR results that may aid in the decision of discharge or admission of acute medical patients.

Abstract Background Soluble urokinase plasminogen activator receptor (suPAR) levels have previously been associated with readmission and mortality in acute medical patients in the ED. However, no specific cut-offs for suPAR have been tested in this population. Methods Prospective observational study of consecutively included acute medical patients. Follow-up of mortality and readmission was carried out for 30- and 90 days stratified into baseline suPAR < 4, 4–6 and > 6 ng/ml. suPAR levels were measured using suPARnostic® Turbilatex assay on a Cobas c501 (Roche Diagnostics Ltd) analyser. Results A total of 1747 acute medical patients in the ED were included. Median age was 70 (IQR: 57–79) and 51.4% were men.

Abstract Objective To evaluate the efficacy and toxicity of SBRT for localized prostate cancer (PCa). Moreover, it is the largest-to-date pilot study to report 5-year outcomes of SBRT for localized PCa from China. Methods In this retrospective study, 133 PCa patients in our center were treated by SBRT with CyberKnife (Accuray) from October 2012 to July 2019. Follow-up was performed every 3 months for evaluations of efficacy and toxicity. Biochemical progression-free survival (bPFS) and toxicities were assessed using the Phoenix definition and the Common Terminology Criteria for Adverse Events (CTCAE) v.5.0 respectively. Factors predictive of bPFS were identified with COX regression analysis. Results 133 patients (10 low-, 21 favorable intermediate-, 31 unfavorable intermediate-, 45 high-, and 26 very high risk cases on the basis of the NCCN risk classification) with a median age of 76 years (range: 54–87 years) received SBRT. The median dose was 36.25Gy (range: 34-37.5Gy) in 5 fractions. Median follow-up time was 57.7 months (3.5–97.2 months). The overall 5-year bPFS rate was 83.6% for all patients. The 5-year bPFS rate of patients with low-, favorable intermediate-, unfavorable intermediate-, high-, and very high risk PCa was 87.5%, 95.2%, 90.5%, 86.3%, and 61.6% respectively. Urinary symptoms were all alleviated after SBRT. All the patients tolerated SBRT with only 1 (0.8%) and 1 (0.8%) patient reporting grade-3 acute and late genitourinary (GU) toxicity, respectively. There were no grade 4 toxicities. Gleason score (P < 0.001, HR = 7.483, 95%CI: 2.686–20.846) was the independent predictor of bPFS rate after multivariate analysis Conclusion SBRT is an efficient and safe treatment modality for localized PCa with high 5-year bPFS rates and acceptable toxicities.

PURPOSE: For endometrial carcinoma patients, there is a need for improved identification of high-risk groups that may benefit from postoperative adjuvant therapy. We therefore studied the prognostic impact of markers for cell proliferation, cell-cycle regulation, and angiogenesis among endometrial carcinoma patients in a population-based setting. PATIENTS AND METHODS: All patients diagnosed with endometrial carcinoma between 1981 and 1985 in Hordaland County, Norway, were studied. The median follow-up for the survivors was 11.5 years (range, 8 to 15 years), with no patient lost because of insufficient follow-up information. Paraffin-embedded tumor tissue, available in 96% of the cases (n = 142), was studied immunohistochemically for microvessel density (MVD) and expression of Ki-67, p53, and p21 proteins. We used the hot spot method for calculation of MVD, and expression of Ki-67 and p21 protein, because this approach may increase the probability of detecting small aggressive clones of possible prognostic relevance. The importance of these tumor markers was investigated in univariate survival analyses and Cox regression analysis. RESULTS: The majority of traditional clinicopathologic variables was significantly associated with the tumor biomarkers. Age, International Federation of Gynecology and Obstetrics (FIGO) stage, histologic type, histologic grade, MVD, as well as Ki-67, p53, and p21 protein expression, all significantly influenced survival in univariate analyses (P ≤ .05). In the Cox regression analysis, age, FIGO stage, MVD, Ki-67 expression, and p53 expression were the only variables with independent prognostic impact (P ≤ .05), whereas histologic type, histologic grade, and p21 expression had no independent influence. A group of high-risk patients with more than one unfavorable marker was identified. CONCLUSION: In addition to age and FIGO stage, MVD, Ki-67, and p53 protein expression showed an independent prognostic impact. Thus, information derived from routine histologic specimens identified a subgroup of high-risk endometrial carcinoma patients in this population-based study.

9519 Background: A 31-GEP test is a validated prognostic tool for predicting the risk of metastasis in CM, classifying patients (pts) as Class 1 (low risk) or Class 2 (high risk). Here we report updated survival analysis from two clinical registry studies (NCT02355574/NCT02355587) designed to prospectively evaluate outcomes in patients for whom the GEP test was part of their clinical care. Methods: Eleven US dermatologic and surgical centers participated using IRB-approved protocols. Participants were CM pts ≥16 years old who had successful 31-GEP test results. Recurrence-free (RFS), distant metastasis-free (DMFS) and overall survival (OS) were assessed using Kaplan-Meier and Cox regression analysis. Results: At data censoring, 340 pts were accrued who had completed at least one follow-up visit. Median age was 58 years (range 18-87), 53.5% were male, median Breslow thickness was 1.2mm (range 0.2-12mm), 18.2% (62/340) were ulcerated, and 11.2% (38/340) had a positive sentinel lymph node (SLN). Median follow-up was 3.2 years for pts without an event. Six percent (16/265) of Class 1 pts had a recurrence compared to 33% (25/75) of Class 2 pts (p < 0.001). Three-year RFS was 96%, 91%, 80%, and 62% for Class 1A, 1B, 2A, and 2B, respectively (p < 0.001). Three-year DMFS was 97%, 93%, 84%, and 80% for Class 1A, 1B, 2A, and 2B, respectively (p < 0.001). Three-year OS was 98%, 90%, 96%, and 74% for Class 1A, 1B, 2A, and 2B, respectively (p < 0.001). Class 2 was an independent predictor of RFS and OS in multivariate analysis (respective HRs: 2.28 and 3.70, p < 0.05). Conclusions: Consistent with results from previous studies, this analysis demonstrates that the GEP test complements conventional staging and improves the ability to identify high-risk CM pts. These results support use of the test for guiding decisions related to follow-up, surveillance, and treatment in CM pts. Clinical trial information: NCT02355574/NCT02355587.

Introduction The aim of this prospective study was to evaluate the association between serum magnesium (Mg) and mortality, in particular the cause-specific mortality of Mg and other risk factors in hemodialysis (HD) patients. Methods We studied a cohort of 185 HD patients receiving thrice-weekly HD treatment, on a dialysate Mg concentration of 0.5 mmol/L. We stratified 3 patient groups according to the level of Mg: lower (<1.1 mmol/L), intermediate-reference (1.1 to <1.3 mmol/L), and higher (Mg >1.3 mm/L). Results During the 5-year follow-up, 60 patients died, with cardiovascular (CV) disease as the predominant cause (73.3%). Hazard ratio (HR) for all-cause and CV mortality were 2.55 and 2.67 in the lower versus intermediate Mg group, but there was no significant association between the higher and intermediate Mg group. Univariate Cox regression analysis showed that Mg <1.1 versus 1.1–1.30 mml/L with HR 2.34, was a significant univariate predictor for increased mortality in addition to the Hb <110 g/L, Alb <40 g/L, C-reactive protein (CRP) ≥10 mg/L and brain natriuretic peptide >1,200 pg/mL However, in the multivariate analysis only CRP ≥10 mg/L with HR 3.89 was a significant predictor of mortality. Subgroup analyses showed that among patients with CRP >10 mg/L, HR for all-cause and CV mortality of the lower versus intermediate Mg group were 1.96 and 2.39, respectively, not reaching significance for the higher versus intermediate Mg group. Conversely, there was no association between Mg level and all-cause and CV mortality within these 3 groups among patients with CRP <10 mg/L. Conclusions Lower serum Mg level was significantly associated with an increased all-cause and cardiovascular mortality in HD patients, especially in inflamed patients.

9573 Background: DecisionDx-Melanoma has been validated as an accurate prognosticator of cutaneous melanoma (CM) metastasis risk. The GEP test classifies CM pts as Class 1 (low risk) or Class 2 (high risk). Interim survival analysis from two clinical registry studies (NCT02355574/NCT02355587) designed to prospectively evaluate outcomes in pts for whom the GEP test was performed is described. Methods: Eleven US dermatologic and surgical centers participated in the IRB-approved protocols. Physicians enrolled CM pts who were ≥16 years old and had successful GEP test results. Endpoints of recurrence-free (RFS), distant metastasis-free (DMFS) and melanoma-specific survival (MSS) were assessed using Kaplan-Meier and Cox regression analysis. As an interim analysis at year 3 of an expected 5-year study, the critical alpha level (p-value) was 0.01. Results: At the time of data extraction, 322 pts were accrued and completed at least one follow-up visit. Median age was 58 years (range 18-87), median Breslow thickness (BT) was 1.2mm, 55% were male, 20% (58/296) were ulcerated, and 15% (36/237 biopsied) had a positive sentinel lymph node (SLN). Median follow-up time was 1.5 years for pts without a recurrence. Of 25 recurrent cases, 80% (20/25) were Class 2 and 40% (10/25) were SLN-positive. Two percent of Class 1 pts had a recurrence compared to 6% (12/201 biopsied) of SLN-negative pts. Of the SLN-negative pts who recurred, 75% (9/12) were called Class 2. Combined GEP and SLN risk prediction identified 88% (21/24) of recurrences. Kaplan-Meier event rates for each class are shown in the table. In Cox multivariate analysis, BT and GEP Class 2 were significant predictors of recurrence (p<0.01 for each). Conclusions: Results of this analysis show that the GEP test provides prognostic information that complements conventional staging and significantly enhances identification of high risk CM pts, consistent with reported validation studies.The results support use of the test for guiding surveillance decisions and enrollment of CM pts in clinical trials. Clinical trial information: NCT02355574, NCT02355587. [Table: see text]

Background. Angiopoietin-like protein 3 (ANGPTL3) plays a pivotal role in lipid metabolism and angiogenesis, and there is growing interest regarding the association between ANGPTL3 and coronary artery disease (CAD). This study aims to investigate whether ANGPTL3 levels can be used to predict the future occurrence of major adverse cardiovascular events (MACEs) in patients with CAD. Methods. Overall, 90 patients with CAD were enrolled between January and December 2012. The study’s primary endpoint was incidence of MACEs. Patient follow-up was completed on June 30, 2017. Results. Following a median follow-up period of 54 months, 33 MACEs had occurred. Patients reporting MACEs had lower statin use (P=0.022) and higher serum C-reactive protein (P<0.001) and serum ANGPTL3 (P<0.001) levels than those without MACEs. Kaplan–Meier analysis revealed higher cumulative incidence of CV events in the high ANGPTL3 group (median ANGPTL3 level ≥ 222.37 ng/mL) than in the low ANGPTL3 group (log-rank P=0.046). Multivariable Cox regression analysis demonstrated that ANGPTL3 levels were independently associated with MACEs in patients with CAD (hazard ratio: 1.003; 95% confidence interval: 1.000–1.005; P=0.026) after adjusted for age, gender, and body mass index, classical risk factors, and potential confounders. Conclusions. Serum ANGPTL3 levels could serve as a biomarker for future occurrence of MACEs in patients with CAD.

4645 Background: Percent biopsy core positivity (%BCP) has been correlated with tumor volume, extraprostatic disease and biochemical progression free survival (bPFS) in surgical series. In an external beam series, it can predict time to progression in a subset of patients. Methods: The percentage of biopsy cores involved with cancer was determined from original pathology reports of 566 patients with clinical stage T1c-T2a, Gleason grade 7–10 and/or PSA 10–20 CaP. These patients had previously been treated on a prospective study that randomized between 20 or 44 Gy of supplemental beam radiation therapy followed by Pd-103 brachytherapy. bPFS was defined as having a serum PSA ≤0.5 ng/ml at last follow-up. Patients were censored at last follow-up if their serum PSA was still decreasing. Results: 5 year bPFS was 79% for the entire group of 566 patients and 84% for the sub-group of 333 patients with %BCP quantified. On Cox regression analysis, biological variables analyzed included PSA, PSA < or ≥ 10, Gleason score, Gleason score < or ≥8, %BCP divided into two different grouping schemes (<34, 34 through 50 and ≥50) and < or ≥50. Treatment related variables analyzed included V100, V100 < or ≥90%, D 90, D 90 < or ≥80%, supplemental beam dose of 20 or 40 Gy. On univariate analysis, significant factors were limited to: %BCP < vs. ≥50 (p = 0.004), %BCP <34 Vs. ≥50% (p = 0.006), PSA, PSA < or ≥10, Gleason score, V100 < or ≥90%, D 90. On multivariate analysis, %BCP was the only significant determinant (p = 0.006) irregardless of which stratification scheme was utilized. For %BCP ≥50%, the hazard ratio for biochemical failure was 3.6 (95% confidence interval 1.4 to 8.8). On Kaplan-Meier analysis, 5 year bPFS was 90% and 79% for patients with <50% and ≥50% cores involved respectively (p = 0.002). Conclusions: With implementation of implant techniques that uniformly meet optimal dosimetric criteria in patients felt to be at intermediate to high risk of failure based on Gleason and PSA, the percent of biopsy cores positive with malignancy emerges as the single most important factor in predicting biochemical failure. There is a statistically significant reduction in bPFS in patients with ≥50% of their core needle biopsies involved with malignancy. No significant financial relationships to disclose.

<b><i>Introduction:</i></b> Chronic kidney disease (CKD) is a risk factor for cardiovascular and all-cause mortality. Recognition of high-risk patients is important and could lead to a different approach and better treatment. The CHA<sub>2</sub>DS<sub>2</sub>-VASc score was originally used to predict cerebral infarction in patients with atrial fibrillation (AF), but it is also a useful predictor of outcome in other cardiovascular conditions, independent of AF. Therefore, the aim of our research was to assess the role of CHA<sub>2</sub>DS<sub>2</sub>-VASc score in predicting cardiovascular and all-cause mortality in CKD patients. <b><i>Methods:</i></b> Stable nondialysis CKD patients were included. At the time of inclusion, medical history data and standard blood results were collected and CHA<sub>2</sub>DS<sub>2</sub>-VASc score was calculated. Patients were followed till the same end date, until kidney transplantation or until their death. <b><i>Results:</i></b> Eighty-seven CKD patients were included (60.3 ± 12.8 years, 66% male). Mean follow-up time was 1,696.5 ± 564.6 days. During the follow-up, 21 patients died and 11 because of cardiovascular reasons. Univariate Cox regression analysis showed that CHA<sub>2</sub>DS<sub>2</sub>-VASc score is a significant predictor of cardiovascular and all-cause mortality. In multivariate Cox regression analysis, in which CHA<sub>2</sub>DS<sub>2</sub>-VASc score, serum creatinine, urinary albumin/creatinine, hemoglobin, high-sensitivity C-reactive protein, and intact parathyroid hormone were included, CHA<sub>2</sub>DS<sub>2</sub>-VASc score was an independent predictor of cardiovascular (HR: 2.04, CI: 1.20–3.45, <i>p</i> = 0.008) and all-cause mortality (HR: 2.06, CI: 1.43–2.97, <i>p</i> = 0.001). The same was true after adding total cholesterol, triglycerides, and smoking status to both the analyses. <b><i>Conclusion:</i></b> The CHA<sub>2</sub>DS<sub>2</sub>-VASc score is a simple, practical, and quick way to identify the risk for cardiovascular and all-cause mortality in CKD patients.
