Abstract Objective Cardiovascular diseases (CVDs) are important complications for patients with rheumatoid arthritis (RA). The study aimed to explore whether serum leptin is associated with a increased risk of cardiovascular (CV) events in patients with RA. Methods Two hundred twenty-three patients with RA were followed for a mean of 40 (range = 8-42) months. Serum leptin levels were measured at baseline. Cox regression analysis was performed to assess the association between leptin levels and the risk of CV events. Results The univariate analysis showed that patients with RA with higher serum leptin levels had higher rates of CV events and CV mortality, respectively (P <.001). The logistic regression model showed that leptin was independently related to CVD history (odds ratio = 1.603, 95% confidence interval [CI], 1.329–2.195; P =.005) after adjusting for confounding factors in patients with RA at baseline. The multivariate Cox proportional hazard model suggested that leptin was an independent prognostic factor for CV events in patients with RA after adjustments were made for clinical confounding factors (hazard ratio = 2.467, 95% CI, 2.019–4.495; P <.001). The Kaplan-Meier analysis showed that compared with patients with RA with leptin levels below the median value (≤15.4 mg/L), patients with leptin above the median value (>15.4 μg/L) had a higher rate of CV events (P <.001). Conclusion Leptin was significantly associated with CV events in patients with RA. Elevated serum leptin levels may be a reliable prognostic factor for predicting CV complications in patients with RA.

Purpose: We aimed to study the influence of fast-track care programs in total hip and total knee replacements (THR and TKR) at Swedish hospitals on the risk of revision and mortality within 2 years after the operation. Methods: Data were collected from the Swedish Hip and Knee Arthroplasty Registers (SHAR and SKAR), including 67,913 THR and 59,268 TKR operations from 2011 to 2015 on patients with osteoarthritis. Operations from 2011 to 2015 Revision and mortality in the fast-track group were compared with non-fast-track using Kaplan–Meier survival analysis and Cox regression analysis with adjustments. Results: The hazard ratio (HR) for revision within 2 years after THR with fast-track was 1.19 (CI: 1.03–1.39), indicating increased risk, whereas no increased risk was found in TKR (HR 0.91; CI: 0.79–1.06). The risk of death within 2 years was estimated with a HR of 0.85 (CI: 0.74–0.97) for TKR and 0.96 (CI: 0.85–1.09) for THR in fast-track hospitals compared to non-fast-track. Conclusions: Fast-track programs at Swedish hospitals were associated with an increased risk of revision in THR but not in TKR, while we found the mortality to be lower (TKR) or similar (THR) as compared to non-fast track.

ObjectiveTo explore whether varicella zoster virus (VZV) infection could increase the risk of disease flares in patients with SLE.MethodsPatients who had VZV reactivations between January 2013 and April 2018 were included from the SLE database (n=1901) of Shanghai Ren Ji Hospital, South Campus. Matched patients with SLE were selected as background controls with a 3:1 ratio. Patients with SLE with symptomatic bacterial infections of the lower urinary tract (UTI) were identified as infection controls. Baseline period and index period were defined as 3 months before and after infection event, respectively. Control period was the following 3 months after the index period. Flare was defined by SELENA SLEDAI Flare Index. Kaplan-Meier analysis, Cox regression model and propensity score weighting were applied.ResultsPatients with VZV infections (n=47), UTI controls (n=28) and matched SLE background controls (n=141) were included. 16 flares (34%) in the VZV group within the index period were observed, as opposed to only 7.1% in UTI controls and 9.9% in background controls. Kaplan-Meier curve revealed that patients with a VZV infection had a much lower flare-free survival within the index period compared with the controls (p=0.0003). Furthermore, after adjusting for relevant confounders including baseline disease activity and intensity of immunosuppressive therapy, Cox regression analysis and propensity score weighting confirmed that VZV infection within 3 months was an independent risk factor for SLE flares (HR 3.70 and HR 4.16, respectively).ConclusionsIn patients with SLE, recent VZV infection within 3 months was associated with increased risk of disease flares.

Recurrence Group

Small bowel neuroendocrine tumors (SBNET) account for most gastrointestinal neuroendocrine tumors. Patients often present with late-stage disease; however, there is little information regarding factors that contribute to recurrence. Database review identified 301 patients diagnosed with SBNET between 1990 and 2013. Univariate analysis included patients who underwent complete resection. Survival was estimated by the Kaplan–Meier method. A total of 147 patients met study criteria. Average age was 60 years (range 21–91); 49 per cent were male. Thirty-seven (25.3%) patients had laparoscopic resection, and 29 (19.9%) patients had only small bowel disease, whereas 108 (72.6%) had nodal metastasis. Five-year overall and disease-free survival were 97.5 and 73.5 per cent. Forty-seven (32%) patients had recurrence. The recurrence group was more likely to have an open operation (59.6 vs 32%, P < 0.01), mesenteric invasion, or lymphatic metastasis (87.2 vs 67%, P < 0.01) compared with the no-recurrence group. Cox regression analysis showed that variables associated with recurrence included nodal disease (HR 9.06, P = 0.03), lymphovascular invasion (LVI) (3.95, P < 0.01), perineural invasion (PNI) (3.48, P < 0.01), and mesenteric involvement (3.77, P = 0.03). Patients with SBNET presenting with nodal metastasis, mesenteric involvement, LVI, or PNI have a higher risk of recurrence. Closer surveillance should be considered after operative resection.

10082 Background: Treatment of Ewing sarcoma pts. usually follows pediatric protocols, both in children and in adults. However, older patients fare poorly in most series. We analyze our experience with the 2001 protocol of the Spanish Society of Pediatric Oncology. Methods: Retrospective analysis. Schema: 6 cycles (cy) of VIDE chemotherapy (CT: vincristine, ifosfamide, etoposide, doxorrubicin). If no progression, local treatment (surgery or RT) and consolidation adjusted to risk: VACx8 (vincristine, dactinomycin, ciclophosphamyde) in standard-risk pts; if increased risk (axial, complete response in lung metastases or non-pulmonary metastases) VACx1, high-dose CT (busulphan-melphalan) and autologous transplant (ATSP). Analysis: induction CT toxicity, pathological response rates, consolidation treatment, disease-free (DFS) and overall survival (OS) (Kaplan- Meier). Log-rank and Cox regression analysis of prognostic factors in OS. Results: 35 patients (01.2003-05.2011). 60% male. Median age 16 y (r 7-57). Axial (43%), extremities (34%), extra-osseous (18%) and ribs (9%). Metastases: 54% (lung 58%, bone 26%, others 12%). > 1 location: 29%. Induction CT: 83% received 6 cy. 6% early progressions and 3% toxic deaths. 196 cycles of CT. Dose reduction (etoposide) in 60%. Grade 3-4 toxicity: neutropenia 13%, anemia 14%, neutropenic fever 13%, diarrhoea-stomatitis 7%.Local treatment: surgery (49%), radiotherapy (29%), none (22%). In 17 resections, > 90% necrosis in 53%. Consolidation: VACx8 29%; VACx1-ATSP in 34%; 37% other treatments (progression). No ATSP-related mortality. Median follow-up: 36 m ( 5-101 m). Median DFS 25 m (16-34 m). Median OS 28 m (15-41 m), 3-year OS 40%. Median time to progression 7 m (0.4-15 m). Median OS from progression 7 m (0.4-15 m). Age < 15 years, a non-axial primary and no extra-pulmonary metastases were favourable prognostic factors in the univariate analysis. Conclusions: Induction CT with the VIDE regimen is feasible in most patients, with a low risk of early progression. Hematological toxicity is substantial but manageable. Adults patients have a worse prognosis compared to pediatric patients. Unfortunately, survival after progression is dismal.

760 Background: Pts included in clinical trials represent the unusual population in mCRC. This study aims to provide oncologist with a better understanding of the potential benefit of CT with CTX in older patients with mCRC KRAS wild type and evaluate prognostic variables on the PFS including the age. Methods: Premium cancer study is a French multicentre prospective community-based registry. 493 pts enrolled and 487 included between September 2009 to March 2012 from 94 French centers and physicians. Pts had to provide written informed consent and protocol submitted to regulatory authorities. Predefined efficacy endpoints was PFS. CTX was administrated at 250 mg/m2 weekly (n=100; 20.3%) or 500 mg/m2 every 2 weeks (n=380;77,2%), other n=13; 2.5%) CT regimen choice was at physician’s discretion.. The main analysis is PFS as well as analysis of prognostic factors of this PFS (29 items including age (< 65 years n=229; 65-74 years n= 165.; ≥75years n=93). Univariate analysis was performed for each covariate, PFS was estimated by Kaplan-Meier curves and compared by log-rank test. univariable Cox regression analysis was used to assess the association between each variable and outcome. Multivariable stepwise Cox models were then fitted for final variable selection of prognostic factors on PFS. Results: Univariate significant prognostic factors for PFS are OMS (0-1 vs 2-3), Tobacco, Site of tumor (right vs other), Number of metastatic organ (1 vs 2-3), Resecability of metastatic disease defined before CT (definitively non resectable metastases vs possible resectable), Surgery of mCRC, folliculitis or xerosis or paronychia grade 0-1 vs 2-4. Age was unidentified as a prognostic factor in univariate analysis. Four factors were independently associated with a better PFS: xerosis [hazard ratio (HR0,651); 95% confidence interval (CI) 0,494-0,857], (WHO PS) 0–1 (HR0,519 ; 95% CI 0,371–0,726) and folliculitis (HR 0,711; 95% CI0,558–0,956) metastases surgery 0,287(CI 0,205-0,403). Conclusions: CTX in combination with standard CT is effective, age is not identified as a prognostic factor for the PFS. Both groups of pts based on age benefit from CTX.

Abstract Glioblastoma (GBM) is the most common and deadly tumor in the central nervous system. Recent studies illuminated that long noncoding RNAs (lncRNAs) serve as competitive endogenous RNAs (ceRNAs) and play an important role in GBM by regulating immune responses. Here, GBM datasets from TCGA database were analyzed to obtain 356 significantly differentially expressed lncRNAs (DE-lncRNAs), 4951 DE-mRNAs, and 34 DE-miRNAs in GBM, respectively. For mRNAs, 369 DE-mRNAs were identified as immune-related genes in Immport database. For DE-lncRNAs, univariate analysis identified 39 DE-lncRNAs with prognostic significance, and 9 DE-lncRNAs are included in ImmLnc database. Then, combined analysis was conducted, by integrating 9 immune related DE-lncRNAs, 369 immune related DE-mRNAs and 34 DE-miRNAs, and generated a ceRNA network composed of 2 upregulated lncRNAs (LINC01268 and CTB-31O20.2), 3 downregulated miRNAs and 5 upregulated mRNAs. Then we focused on LINC01268 and CTB-31O20.2, and Kaplan-Meier survival, univariate and multivariate Cox regression analysis showed that LINC01268 and CTB-31O20.2 serve as independent protective prognostic markers in GBM. Finally, LINC01268 and CTB-31O20.2 overexpression was conducted in GBM cell U251. CCK8, transwell and scratch healing assay indicated that LINC01268 and CTB-31O20.2 inhibits GBM cell line U251 proliferation, invasion and migration. To sum up, LINC01268 and CTB-31O20.2 are independent prognostic immune related markers, and reduces cancer cell proliferation and metastasis in GBM.

(1) Background: This study aimed to investigate the association between radioactive iodine (RAI) and long-term cardiovascular disease (CVD) morbidity/mortality in thyroid cancer. (2) Methods: The study was conducted using data from the Taiwan National Health Insurance Database during 2000–2015. Thyroid cancer patients aged ≥20 years were categorized into RAI (thyroidectomy with RAI) and non-RAI (thyroidectomy only) groups. The Cox proportional hazard regression model and Kaplan–Meier method were used for analysis. (3) Results: A total of 13,310 patients were included. Kaplan–Meier analysis demonstrated that the two groups had similar cumulative risks of CVD (log-rank p = 0.72) and CVD-specific mortality (log-rank p = 0.62). On Cox regression analysis of different RAI doses, the risk of CVD was higher in the cumulative dosage >3.7 GBq (hazard ratio = 1.69, 95% confidence interval = 1.24–2.40, p < 0.001). (4) Conclusions: RAI was not associated with an increased risk of CVD in thyroid cancer. However, CVD surveillance is indicated in the patients receiving the cumulative RAI dosage above 3.7 GBq.

3 Background: While treatment-related lymphopenia (TRL) is common and associated with poorer survival in multiple solid malignancies, little data exists for anal cancer. We evaluated TRL and its association with survival in anal cancer patients treated with chemoradiation (CRT). Methods: A retrospective analysis of 140 patients with non-metastatic anal squamous cell carcinoma (SCC) treated with definitive CRT was performed. Total lymphocyte counts (TLC) at baseline and monthly intervals up to 12 months after initiating CRT were analyzed. Multivariable Cox regression analysis was performed to evaluate the association between overall survival (OS) and TRL, dichotomized by G4 TRL ( < 0.2k/μl) two months after initiating CRT. Kaplan-Meier and log-rank tests were used to compare OS between patients with versus without G4 TRL. Results: Median time of follow-up was 55 months. Prior to CRT, 95% of patients had a normal TLC ( > 1k/μl). Two months after initiating CRT, there was a median of 71% reduction in TLC from baseline and 84% of patients had TRL: 11% G1, 31% G2, 34% G3, and 8% G4. On multivariable Cox model, G4 TRL at two months was associated with a 3.7-fold increased risk of death (p = 0.013). On log-rank test, the 5-year OS rate was shorter in the cohort with versus without G4 TRL at two months (32% vs. 86%, p < 0.001). Conclusions: TRL is common and may be another prognostic marker of OS in anal cancer patients treated with CRT. The association between TRL and OS supports the hypothesis that host immunity plays an important role in survival among patients with anal cancer. These results support ongoing efforts of randomized trials underway to evaluate the potential role of immunotherapy in localized anal cancer.

Abstract Background Citric acid–based bicarbonate haemodialysis (CIT-HD) has gained more clinical acceptance over the last few years in France and is a substitute for other acidifiers [e.g. acetic acid (CH3COOH) and hydrochloric acid (HCl)]. This trend was justified by several clinical benefits compared with CH3COOH as well as the desire to avoid the consequences of the corrosive action of HCl, but a nationwide clinical report raised concerns about the long-term safety of CIT-HD. The aim of this study was to assess the long-term effects of CIT-HD exposure on patient outcomes in western France. Methods This is a population-based retrospective multicentre observational study performed in 1132 incident end-stage kidney disease patients in five sanitary territories in western France who started their renal replacement therapy after 1 January 2008 and followed up through 15 October 2018. Relevant data, collected prospectively with the same medical software, were anonymously aggregated for the purposes of the study. The primary goal of this study was to investigate the effects of citrate exposure on all-cause mortality. To provide a control group to CIT-HD one, propensity score matching (PSM) at 2:1 was performed in two steps: the first analysis was intended to be exploratory, comparing patients who received citrate ≤80% of the time (CIT-HD ≤80) versus those who received citrate &gt;80% of the time (CIT-HD &gt;80), while the second analysis was intended to be explanatory in comparing patients with 0% (CIT-HD0) versus 100% citrate time exposure (CIT-HD100). Results After PSM, in the exploratory part of the analysis, 432 CIT-HD ≤80 patients were compared with 216 CIT-HD &gt;80 patients and no difference was found for all-cause mortality using the Kaplan–Meier model (log-rank 0.97), univariate Cox regression analysis {hazard ratio [HR] 1.01 [95% confidence interval (CI) 0.71–1.40]} and multivariate Cox regression analysis [HR 1.11 (95% CI 0.76–1.61)] when adjusted for nine variables with clinical pertinence and high statistical relevance in the univariate analysis. In the explanatory part of the analysis, 316 CIT-HD0 patients were then compared with 158 CIT-HD100 patients and no difference was found using the Kaplan–Meier model (log-rank 0.06), univariate Cox regression analysis [HR 0.69 (95% CI 0.47–1.03)] and multivariate Cox regression analysis [HR 0.87 (95% CI 0.57–1.33)] when adjusted for seven variables with clinical pertinence and high statistical relevance in the univariate analysis. Conclusions Findings of this study support the notion that CIT-HD exposure ≤6 years has no significant effect on all-cause mortality in HD patients. This finding remains true for patients receiving high-volume online haemodiafiltration, a modality most frequently prescribed in this cohort.

Abstract Background To compare the incidence of osteoporotic fractures in patients with rheumatoid arthritis (RA) with matched controls from a university hospital. Methods Consecutive RA patients (n = 100) were matched (age and sex) with controls (1:2). The follow-up period began at the index date, defined as the date of diagnosis for RA patients and the date of the first medical claim at the Health Management Organization (HMO) for non-RA patients. Fracture incidence rates per 1000 persons-years (PY) for distinct types of fractures were calculated. Multivariate cox regression analysis was performed to identify factors associated with fractures. Results One hundred RA patients were followed for a total of 975.1 patients-years and 200 controls for 1485.7 patients-years. No difference was found in the overall fracture incidence rate per 1000 PY between RA and controls (19.5, 95% CI 12.7–28.6 vs 12.1, 95% CI 7.7–18.7, p = 0.07). In the Cox regression analysis, only age (HR 1.06, 95% CI 1.02–1.11, p = 0.006) and history of a prior fracture (HR 9.85, 95% CI 2.97–32.64, p <  0.001) were associated with fractures after the index date. The stratified analysis of the fractures by location showed that only the vertebral fractures were more frequent in RA patients compared with controls (12.9 per 1000 PY, 95% CI 8.9–25.8, vs. 3.4, 95% CI 1.4–8.1, respectively, p = 0.01). Conclusion Patients with RA didn’t show an overall increased risk of osteoporotic fractures compared with matched controls, but vertebral fractures were more frequently observed in patients with RA.
