Abstract Background Epithelial-mesenchymal transition (EMT) has been implicated in the invasion and progression of gliomas, the present study investigated EMT-related long noncoding (lnc)RNAs in gliomas.Methods Candidate lncRNAs screened from a glioma dataset in The Cancer Genome Atlas were used to construct EMT-related lncRNA coexpression networks in order to identify EMT-related lncRNAs; these were validated using the Chinese Glioma Genome Atlas (CGGA). Gene set enrichment analysis and principal component analysis (PCA) were used to annotate lncRNA functions. We established an EMT-related lncRNA signature composed of 9 lncRNAs (HAR1A, LINC00641, LINC00900, MIR210HG, MIR22HG, PVT1, SLC25A21-AS1, SNAI3-AS1, and SNHG18) that could distinguish between low- and high-risk glioma patients. The functions of the identified lncRNAs were evaluated by constructing a competing endogenous RNA network.Results The low-risk group had longer overall survival (OS) than the high-risk group (P<0.0001). High-risk patients also had no deletion on chromosome arms 1p and/or 19q, expressed wild-type isocitrate dehydrogenase, and had higher World Health Organization (WHO) tumor grade. The signature was an independent factor significantly associated with OS (P=0.041, hazard ratio=1.806). These findings were validated in the CGGA dataset. PCA also revealed differences in EMT status between low- and high-risk patients. Competing endogenous RNA network showed that complex lncRNA–microRNA–mRNA interactions potentially contributing to EMT progression in glioma. Conclusion Our results demonstrate that the EMT-related 9-lncRNA signature has prognostic value for glioma patients.

Abstract Background: Esophageal carcinoma (ESCA) is a malignant tumor with high invasiveness and mortality. Autophagy has multiple roles in the development of cancer; however, there are limited data on autophagy genes associated with long non-coding RNAs (lncRNAs) in ESCA. The purpose of this study was to screen potential diagnostic and prognostic molecules, and to identify gene co-expression networks associated with autophagy in ESCA. Methods: We downloaded transcriptome expression profiles from The Cancer Genome Atlas and autophagy-related gene data from the Human Autophagy Database, and analyzed the co-expression of mRNAs and lncRNAs. In addition, the diagnostic and prognostic value of autophagy-related lncRNAs was analyzed by multivariate Cox regression. Furthermore, Kyoto Encyclopedia of Genes and Genomes analysis was carried out for high-risk patients, and enriched pathways were analyzed by gene set enrichment analysis. Results: The results showed that genes of high-risk patients were enriched in protein export and spliceosome. Based on Cox stepwise regression and survival analysis, we identified seven autophagy-related lncRNAs with prognostic and diagnostic value, with the potential to be used as a combination to predict the prognosis of patients with ESCA. Finally, a co-expression network related to autophagy was constructed. Conclusion: These results suggest that autophagy-related lncRNAs and the spliceosome play important parts in the pathogenesis of ESCA. Our findings provide new insight into the molecular mechanism of ESCA and suggest a new method for improving its treatment.

Abstract Background: Autophagy and long non-coding RNAs (lncRNAs) have been the focus of research on the pathogenesis of melanoma. However, the autophagy network of lncRNAs in melanoma has not been reported. The purpose of this study was to investigate the lncRNA prognostic markers related to melanoma autophagy and predict the prognosis of patients with melanoma.Methods: We downloaded RNA-sequencing data and clinical information of melanoma from The Cancer Genome Atlas. The co-expression of autophagy-related genes (ARGs) and lncRNAs was analyzed. The risk model of autophagy-related lncRNAs was established by univariate and multivariate COX regression analyses, and the best prognostic index was evaluated combined with clinical data. Finally, gene set enrichment analysis was performed on patients in the high- and low-risk groups.Results: According to the results of the univariate COX analysis, only the overexpression of LINC00520 was associated with poor overall survival, unlike HLA-DQB1-AS1, USP30-AS1, AL645929, AL365361, LINC00324, and AC055822. The results of the multivariate COX analysis showed that the overall survival of patients in the high-risk group was shorter than that recorded in the low-risk group (p<0.001). Moreover, in the receiver operating characteristic curve of the risk model we constructed, the area under the curve (AUC) was 0.734, while the AUC of T and N was 0.707 and 0.658, respectively. The Gene Ontology was mainly enriched with the positive regulation of autophagy and the activation of the immune system. The results of the Kyoto Encyclopedia of Genes and Genomes enrichment were mostly related to autophagy, immunity, and melanin metabolism.Conclusion: The positive regulation of autophagy may slow the transition from low-risk patients to high-risk patients in melanoma. Furthermore, compared with clinical information, the autophagy-related lncRNAs risk model may better predict the prognosis of patients with melanoma and provide new treatment ideas.

Abstract Background Following Myocardial Infarction (MI), patients are at increased risk for recurrent cardiovascular events, particularly during the immediate period. Yet some patients are at higher risk than others, owing to their clinical characteristics and comorbidities, these high-risk patients are less often treated with guideline-recommended therapies. Aim To examine temporal trends in treatment and outcomes of patients with MI according to the TIMI risk score for secondary prevention (TRS2°P), a recently validated risk stratification tool. Methods A retrospective cohort study of patients with an acute MI, who underwent percutaneous coronary intervention and were discharged alive between 2004–2016. Temporal trends were examined in the early (2004–2010) and late (2011–2016) time-periods. Patients were stratified by the TRS2°P to a low (≤1), intermediate (2) or high-risk group (≥3). Clinical outcomes included 30-day MACE (death, MI, target vessel revascularization, coronary artery bypass grafting, unstable angina or stroke) and 1-year mortality. Results Among 4921 patients, 31% were low-risk, 27% intermediate-risk and 42% high-risk. Compared to low and intermediate-risk patients, high-risk patients were older, more commonly female, and had more comorbidities such as hypertension, diabetes, peripheral vascular disease, and chronic kidney disease. They presented more often with non ST elevation MI and 3-vessel disease. High-risk patients were less likely to receive drug eluting stents and potent anti-platelet drugs, among other guideline-recommended therapies. Evidently, they experienced higher 30-day MACE (8.1% vs. 3.9% and 2.1% in intermediate and low-risk, respectively, P<0.001) and 1-year mortality (10.4% vs. 3.9% and 1.1% in intermediate and low-risk, respectively, P<0.001). During time, comparing the early to the late-period, the use of potent antiplatelets and statins increased among the entire cohort (P<0.001). However, only the high-risk group demonstrated a significantly lower 30-day MACE (P=0.001). During time, there were no differences in 1-year mortality rate among all risk categories. Temporal trends in 30-day MACE by TRS2°P Conclusion Despite a better application of guideline-recommended therapies, high-risk patients after MI are still relatively undertreated. Nevertheless, they demonstrated the most notable improvement in outcomes over time.

Abstract BMT remains the treatment of choice for early BM relapse of childhood ALL. We reasoned that further intensification of cytoreductive therapy pre-BMT may further improve survival amongst those with the highest risk of treatment failure, early BM relapse (BFM groups S3/4) and high level MRD pre-BMT. A cohort of 32 patients transplanted at a single institution (1996–1999) provided an historical control. 8 high risk patients transplanted 1999–2000 received additional fludarabine cytoreduction therapy at the time of transplant (FLA group). MRD analysis and time to relapse were used in a subsequent cohort of 22 patients (BMT 2000–2002) to allocate those at highest risk of treatment failure to receive a further cytoreductive block, FLX, pre-BMT. Method. All patients were conditioned with cyclophosphamide (60mg/m2 x2) and TBI (14.4 Gy). UD and haplo-BMT were T-cell depleted with Campth-1M in vitro and Campath-1G day -9 to -5 (Control and FLA group), and by Miltenyi CD34+ cell depletion (FLX group). GvHD prophylaxis - CSA + MTX for matched related, CSA for Campath treated grafts and none for Miltenyi grafts. The FLA group received fludarabine 25mg/m2 from d −12 to d −10. Patients with on treatment relapse (S4) or high level MRD pre-BMT (MRD++) in the FLX group received DaunoXome 100mg/m2, fludarabine 30mg/m2 x 5d and cytosine 2g/m2 x 5d 3 weeks prior to BMT. Patients and donors. Control group: 28 precursor-B ALL 4 T-ALL; donors - 7 matched related, 13 matched unrelated (MUD) and 12 mismatched unrelated (MMUD); 14 S2, 18 S3/4. FLA group: 5 presursor-B ALL and 3 T-ALL; donors - 2 SIB, 4 MUD, 1 MMUD and 2 haplo; all S4. FLX group: 21 precursor-B and 1 T-ALL; donors - 6 SIB, 7 MUD, 5 MMUD and 4 haplo;13 S2, 9 S4. 7 patients received FLX intensified conditioning (6 S4, 5 high level MRD ++). 3 high risk patients violated protocol and did not receive FLX (1 age &lt;1yr on treatment relapse, 2 S2 MRD ++). Results. Considering those in the high-risk S3/4 group, there was no significant difference in OS between the 3 groups. Survival by study and risk group Study S2 S3/4 Overall Control 10/14 (71%) 3/18 (17%) 13/32 (41%) FLA 2/8 (25%) 2/8 (25%) FLX 11/13 (85%) 3/9 (33%) 14/22 (64%) No excess cardiac events were seen. The TRM is higher in the FLX group than in the control. Outcome data Study TRM Relapse Alive Total Control 3 16 13 32 S2 2 2 10 14 S3/4 1 14 3 18 FLA 3 3 6 12 S2 - - - - S3/4 3 3 3 9 FLX 6 2 14 22 S2 2 0 11 13 S3/4 4 2 3 9 Total 12 21 33 66 2 of 7 patients treated with FLX are in CCR, 2 relapsed and 3 died of TRM. The 3 high risk patients in the FLX study, but who did not receive FLX, are also in CCR. Survival in those in the S2 group (late BM relapse) has been good throughout the study period. Conclusion. In this study the addition of intensive pre-BMT conditioning has not improved survival amongst high risk (S3/4 or MRD ++ pre-BMT) relapses. The number of post-BMT relapses has fallen but this is not clearly related to the use of FLX. The use of more haploidentical donors, more immunosupressive BMT regimes and additional cytoreductive chemotherapy may have contributed to the increased TRM seen. Time and site of relapse remain the clearest predictor of outcome. Further novel strategies are required to improve survival for the S4 risk group. The good OS for children receiving BMT in the S2 group should be noted.

Abstract Background and aims: Serum galactomannan (GM) is used as a screening test for the early diagnosis of Aspergillus infection in high risk patients for fungal invasive infection. Serial GM levels analysis have proven to be useful in the high risk clinical setting patients, specially when neutropenic and not receiving anti-mold agents prophylaxis. There is a lack of information regarding the benefit of GM in patients undergoing allogeneic hematopoietic cell transplant (HCT). The aim of this work is to measure the real clinical benefit of the serial periodic determination of GM in the post allo-HCT period. Material and methods: 139 consecutive patients who receivedan allo-HCT (59% related family member donorsand 41% unrelated donors) in our centre for five years (since January 2010 to February 2015) were included in the study. Median age was 46 years. Baseline characteristics of these patients are shown in figure 1. Patients were monitored with GM weekly and received primary prophylaxis with fluconazole since the admission until the immunosuppression was tapered. In order to find a population that could benefit the most for AGA monitoring, we classified our population in low risk patients for invasive fungal infection (IFI) versus high risk patients (those with previous proven or probable IFI or those suffering from GVHD; high risk patients received anti-mold prophyllaxis, mainly with voriconazole or posaconazole). Patients considered as low risk who suffered from Graft versus Host Disease (GVHD) in the ulterior outcome, were censored for low risk and considered as high risk since the development of GVHD, and therefore anti-mold agent prophylaxis was started. GM positivity was determined according standard criteria. When GM positivity was detected, radiological and clinical studies (chest/sinus CT scans, cultures, etc.) to discard Aspegillosis were done as soon as possible. Every patient was followed up prospectively until the last medical consultation or decease. Results: Global overall survival (OS) for the entire cohort was 55.39% and cumulative incidence for severe GVHD grade III/IV was 49.5%. During the follow up, GM became positive in 31/139 (22%) cases. With this approach, the global false positive and false negative rate was 31% and 6% respectively.110/139 (79.14%) patients were identificated as low risk cases. We observed GM positivization in 1.81% (2/110) and 37.18% (29/78) for low and high group respectively. All 2 positive GM in the low risk group were false positives. Regarding the high risk group, 34.48% (10/29) were false positives while in the rest 19 patients (65.52%), subsequent radiological and clinical findings allowed us to diagnose Aspergillus infection (besides they received anti-mold agent prophylaxis). Conclusions: In our experience there is not enough evidence for supporting making serial monitoring with GM in low risk patients for IFI in the post allo-HCT period. However it may be an useful tool in high risk patients. Table 1.

1577 Background: Venous thromboembolism (VTE) poses a significant health risk to cancer patients and is one of the leading causes of death among this population. The most effective way to prevent VTE and reduce its prominence as a public health burden is by identifying high-risk patients and administering prophylactic measures. In 2008, Khorana et al. developed a model that classified patients by risk based on clinical factors. Methods: We conducted a retrospective study to test this model’s efficacy, on 150 patients with cancer receiving chemotherapy at an outpatient oncology clinic between January 1 and August 1, 2011. We aggregated data and assigned points based on the five factors in the Khorana model: site of cancer with 2 points for very high-risk site and 1 point for high-risk site, 1 point each for leukocyte counts more than 11 x 109/L, platelet counts greater than 350 X 109/L, hemoglobin levels less than 100 g/L and/or the use of erythropoiesis-stimulating agents, and BMI greater than 35 kg/m2 (Khorana et al., Blood 2008). Based on this scoring system, patients with 0 points were grouped into the low-risk category, those with 1-2 points were considered intermediate-risk, and those with 3-4 points were classified as high-risk. Results: As shown in the table, VTE incidence for the low-risk group was 1.9%, intermediate-risk group was 3.9%, and high-risk group was 9.1%. Conclusions: High-risk patients were about 4.5 times more likely to develop a VTE than low risk patients. These results provide valuable insight in determining which patients might benefit from prophylaxis and in motivating the design of prospective clinical trials that assess the VTE predictive model in various ambulatory cancer settings.

Although great progresses have been made in the diagnosis and treatment of hepatocellular carcinoma (HCC), its prognostic marker remains controversial. In this current study, weighted correlation network analysis and Cox regression analysis showed significant prognostic value of five autophagy-related long non-coding RNAs (AR-lncRNAs) (including TMCC1-AS1, PLBD1-AS1, MKLN1-AS, LINC01063, and CYTOR) for HCC patients from data in The Cancer Genome Atlas. By using them, we constructed a five-AR-lncRNA prognostic signature, which accurately distinguished the high- and low-risk groups of HCC patients. All of the five AR lncRNAs were highly expressed in the high-risk group of HCC patients. This five-AR-lncRNA prognostic signature showed good area under the curve (AUC) value (AUC = 0.751) for the overall survival (OS) prediction in either all HCC patients or HCC patients stratified according to several clinical traits. A prognostic nomogram with this five-AR-lncRNA signature predicted the 3- and 5-year OS outcomes of HCC patients intuitively and accurately (concordance index = 0.745). By parallel comparison, this five-AR-lncRNA signature has better prognosis accuracy than the other three recently published signatures. Furthermore, we discovered the prediction ability of the signature on therapeutic outcomes of HCC patients, including chemotherapy and immunotherapeutic responses. Gene set enrichment analysis and gene mutation analysis revealed that dysregulated cell cycle pathway, purine metabolism, and TP53 mutation may play an important role in determining the OS outcomes of HCC patients in the high-risk group. Collectively, our study suggests a new five-AR-lncRNA prognostic signature for HCC patients.

Aim. To assess the specifics of antihypertension therapy (AHT) in hypertensives of various cardiovascular risk, in the registry of chronic non-communicable diseases in Tyumenskaya oblast.Material and methods. A random sample studied, of 1704 patients with hypertension, inhabitants of Tyumenskaya oblast (region), ascribed to dispensary follow-up. Mean age 62±7,5 y.o. Of those 31,5% (n=537) males. The prevalence and efficacy of AHT assessed according to cardiovascular risk level. The significance was evaluated with the criteria χ2.Results. AHT was characterized by the growth of the frequency of treatment approaches with cardiovascular risk consideration. Regular treatment took 33,9% patients of low and moderate risk vs 41,3% of high and very high (p<0,01). In the male group such tendency also took place. Gender specifics of AHT was characterized by that in the groups of high and very high risk females took medications significantly more commonly than males — 46,6% vs 29,1% in high risk group (p<0,01) and 47,5% vs 30% in very high risk group (p<0,01). With the increase of the risk level, there was decline of treatment efficacy — from 95% in low risk group to 32,5% in very high risk group; 53,1% of the participants were taking monotherapy, 32,9% — two drugs, 14,0% — ≥3 drugs. With the increase of risk grade there is tendency to increase of combinational AHT, however with no significant increase of efficacy. Treatment efficacy in high and very high risk patients comparing to patients with low and moderate risk was significantly lower — 33,1% vs 69,7% (p<0,01), respectively. Statins intake among the high and very high risk patients was 10,6-11,0% males and 7,8% females (p<0,05).Conclusion. AHT in hypertensives in Tymenskaya oblast, under dispensary follow-up, is characterized by insufficient usage of combinational drugs. With the raise of cardiovascular risk there is tendency to higher rate of combinational AHT. However there is no significant increase in efficacy of treatment with the increase of medications number. A very low rate of statins intake is noted. The obtained specifics witness for the necessity to optimize AHT among the high and very high risk patients — inhabitants of Tyumenskya oblast.
