Abstract Background: More and more cases of leukemia with heart injury have been reported, mostly due to tumor cell infiltration, endothelial injury and high viscosity of leukemia cells in circulating blood. To evaluate whether the newly diagnosed acute leukemia patients have suffered heart-related injuries, and determine the possible related factors, we carried out this study. Methods: From January 2015 to August 2019, we retrospectively selected 408 patients from the Department of Hematology and Cardiology, Zhongnan Hospital of Wuhan University. There were 200 newly diagnosed acute leukemia patients (including 15 acute hyperleukocytic leukemia patients), 105 patients without cancer and no known heart disease, and 103 cases of confirmed coronary heart disease. We collected the basic information of patients, echocardiographic data and myocardial enzyme results. We also followed up all newly diagnosed acute leukemia patients for prognostic analysis. All data were logarithmically transformed to make the data normally distributed. Normally distributed samples were compared using independent sample t-tests, Mann-Whitney U rank sum test was used for non-normally distributed samples and qualitative data was using chi-square test. The log-rank test was used to perform univariate analysis through Kaplan-Meier curves, and meaningful values were screened for multivariate COX regression analysis. The statistical analysis was performed with the SPSS software. Results: Compared with the control group, patients with newly diagnosed acute leukemia had already experienced some heart-related injuries. The average values of myocardial enzyme indexes such as CKMB,LDH,hs-cTnI,BNP and echocardiography indexes such as LV,EDV,ESV,SV,EF were all significantly different. But the degree of heart damage was lower than that of the coronary heart disease group. Compared with hyperleukocytic leukemia, non-hyperleukocytic leukemia had suffered more serious heart damage, especially myocardial enzyme indexes such as HBDH and LDH were significantly increased. Analyze the relationship between age, gender, cardiovascular risk factors (hypertension, diabetes and smoking history), myocardial enzyme indexes, echocardiography indexes and survival, to screen for risk factors related to the prognosis of the disease. Variables with statistically significant effect measurement values include age (p<0.001), LDH (p=0.018), and EF (p=0.053). In addition, the meaningful variables in the previous single-factor analysis were subjected to multi-factor COX regression analysis, and age (HR = 1.515, 95 %CI, 0.994-2.311, P = 0.001), EF (HR = 0.526, 95% CI, 0.361-0.766, P=0.05) were independent factors related to the prognosis of patients. Classification based on the clinical diagnosis of echocardiography in newly diagnosed acute leukemia patients, significant differences in myocardial enzymes and related indicators of echocardiography were included for ROC plots. The 3 indicators with the highest results for the area under the curve (AUC) from ROC plots were LV, EDV and HBDH, AUC were 0.721,0.619 and 0.615, respectively. This result revealed that the best predictor of leukemia myocardial damage was LV. It showed the predict ability of LV (AUC = 0.721, 95%CI = 0.643-0.799, P <0.001; sensitivity = 42.4%; specificity = 91.8%). Conclusions： According to our research, we have confirmed that the cardiac function of newly diagnosed acute leukemia patients is significantly different from that of patients without leukemia, and these differences will have an impact on the prognosis of patients. Among them, the best predictor of leukemia heart damage is LV, and EF is an independent risk factor for the prognosis of leukemia patients. In addition, newly diagnosed acute leukemia patients are more likely to have an increase in left ventricular diameter and a significant decrease in ejection fraction. Further research is needed to explore the specific mechanism in the future. Disclosures No relevant conflicts of interest to declare.

Waist To Hip Ratio

Background: Heart failure (HF) is considered one of the most common complications of coronary heart disease (CHD), with a higher incidence of readmission and mortality. Thus, exploring the risk factors related to the prognosis is necessary. Moreover, the effect of the waist-to-hip ratio (WHR) on HF patients with revascularized CHD is still unclear. Thus, we aimed to assess the influence of WHR on the prognosis of HF patients with revascularized CHD.Methods: We collected data of HF patients with revascularized CHD who were referred to the Cardiac Rehabilitation Clinic of PLA Hospital from June 30, 2015, to June 30, 2019. Cox proportional hazard regression analysis was used to determine the relationship between WHR and prognosis of HF patients with revascularized CHD. Patients were divided into higher and lower WHR groups based on the cutoff WHR value calculated by the X-tile software. Cox regression analysis was used to analysis the two groups. We drew the receiver operating characteristic curve (ROC) of WHR and analyzed the differences between the two groups. Endpoints were defined as major adverse cardiac events (MACE) (including all-cause mortality, non-fatal myocardial infarction, unscheduled revascularization, and stroke).Results: During the median follow-up of 39 months and maximum follow-up of 54 months, 109 patients were enrolled, of which 91.7% were males, and the mean age was 56.0 ± 10.4 years. WHR was associated with the incidence of MACE in the Cox regression analysis (p = 0.001); an increase in WHR of 0.01 unit had a hazard ratio (HR) of 1.134 (95%CI: 1.057–1.216). The WHR cutoff value was 0.93. Patients in the higher WHR group had a significantly higher risk of MACE than those in the lower WHR group (HR = 7.037, 95%CI: 1.758–28.168). The ROC area under the curve was 0.733 at 4 years. Patients in the higher WHR group had a higher body mass index (BMI; 26.7 ± 3.5 vs. 25.4 ± 2.4, P = 0.033) than patients in the lower WHR group.Conclusions: WHR is an independent risk factor of the long-term prognosis of Chinese HF patients with revascularized CHD. Patients with WHR ≥ 0.93 require intensified treatment. Higher WHR is related to higher BMI and ΔVO2/ΔWR.

Abstract Background: To evaluate the risk factors for the morbidity and prognosis of lung metastases (LM) in patients with newly diagnosed ovarian carcinoma (OC). Methods: Based on the Surveillance, Epidemiology, and End Results (SEER) dataset, OC patients from 2010 and 2016 were retrospectively analyzed. Risk factors for the morbidity of LM in OC patients and their survival were assessed by logistic regression analysis and Kaplan-Meier and Gray method, respectively. Cox regression analysis was performed to identify risk factors for the prognosis of OC patients with LM, and their prognostic potentials were further validated by two established nomograms.Results: There are 27,123 eligible OC patients were enrolled in the study, with the morbidity of LM at 5.61% (1,521/27,123). Logistic regression models illustrated that T3 stage [odds ratio (OR)=2.74, 95%CI=2.09-3.66, P<0.01], advanced N stage (OR=1.86, 95%CI=1.62-2.14, P<0.01), and the prevalence of bone metastasis (OR=3.78, 95%CI=2.79-5.11, P<0.01), brain metastasis (OR=4.67, 95%CI=2.50-8.63, P<0.01) and liver metastasis (OR=3.60, 95%CI=3.14-4.12, P<0.01) were all significantly correlated with the morbidity of LM in OC patients. Median survival for OC patients with LM was 11 months (interquartile range, 3 to 25 months). Cox regression analyses illustrated over 80 years of age [hazard ratio (HR)=2.52, 95%CI=2.33-2.72, P<0.01] and positive expression of cancer antigen 125 (CA-125, HR=1.63, 95%CI=1.47-1.82, P<0.01) were significantly correlated with the high mortality of LM, while chemotherapy (HR=0.62, 95%CI=0.59-0.65, P<0.01) was significantly correlated with the low mortality. Two nomograms were established to examine the concordance index (C-index), calibration curves, the area under the curve (AUC), decision curve analyses (DCAs) and clinical impact curves (CICs), which validated the prognostic potentials of identified risk factors in OC patients with LM. Conclusion: The population-based cohort study provides references for guiding clinical screening and individualized treatment of OC patients with LM.

e14533 Background: Lymphopenia frequently occurs after concomitant chemoradiation (CCRT) in patients with glioblastoma (GBM) and is associated with worse overall survival (OS). A few studies have tried to identify risk factors for lymphopenia; however, the results were not clear. We aimed to identify potential risk factors for lymphopenia, focusing on the use of dexamethasone to control cerebral edema in patients with GBM. Methods: The electronic medical records of 180 patients with newly diagnosed GBM treated at our institution between 2009 and 2017 were retrospectively examined. Acute lymphopenia was defined as TLC (total lymphocyte count) less than 1,000 cells/mm3 at 4 weeks after completion of CCRT. Multivariate logistic regression analysis was used to identify independent risk factors for lymphopenia, and Cox regression analysis was used to identify independent risk factors for OS. Results: Of the 125 eligible patients, 40 patients (32.0%) developed acute lymphopenia. Female sex and median daily dexamethasone dose > 2mg after initiation of CCRT were independent risk factors for acute lymphopenia on multivariate analysis. Acute lymphopenia, extent of surgical resection, and performance status were associated with OS; however, dexamethasone use itself was not an independent risk factor for poor OS. Conclusions: Female sex, median daily dexamethasone dose > 2 mg after initiation of CCRT until four weeks after completion of CCRT may be associated with acute lymphopenia. However, dexamethasone use itself did not affect OS in patients newly diagnosed with GBM. These results should be validated by further prospective studies controlling for other confounding factors.

Background: The aim of our study was to develop a nomogram model to predict overall survival (OS) and cancer-specific survival (CSS) in patients with gastric signet ring cell carcinoma (GSRC). Methods: GSRC patients from 2004 to 2015 were collected from the Surveillance, Epidemiology, and End Results (SEER) database and randomly assigned to the training and validation sets. Multivariate Cox regression analyses screened for OS and CSS independent risk factors and nomograms were constructed. Results: A total of 7,149 eligible GSRC patients were identified, including 4,766 in the training set and 2,383 in the validation set. Multivariate Cox regression analysis showed that gender, marital status, race, AJCC stage, TNM stage, surgery and chemotherapy were independent risk factors for both OS and CSS. Based on the results of the multivariate Cox regression analysis, prognostic nomograms were constructed for OS and CSS. In the training set, the C-index was 0.754 (95% CI = 0.746-0.762) for the OS nomogram and 0.762 (95% CI: 0.753-0.771) for the CSS nomogram. In the internal validation, the C-index for the OS nomogram was 0.758 (95% CI: 0.746-0.770), while the C-index for the CSS nomogram was 0.762 (95% CI: 0.749-0.775). Compared with TNM stage and SEER stage, the nomogram had better predictive ability. In addition, the calibration curves also showed good consistency between the predicted and actual 3-year and 5-year OS and CSS. Conclusion: The nomogram can effectively predict OS and CSS in patients with GSRC, which may help clinicians to personalize prognostic assessments and clinical decisions.

The majority of patients with myelodysplastic syndromes (MDS) require regular red blood cell (RBC) transfusions. Alloimmunization (AI) against blood products is an adverse event, causing time-consuming RBC compatibility testing. The reported incidence of AI in MDS patients varies greatly. Even though different studies on AI in MDS patients have been performed, there are still knowledge gaps. Current literature has not yet fully identified the risk factors and dynamics of AI in individual patients, nor has the influence of disease modifying treatment (DMT) been explored. Therefore, we performed this study to evaluate the effect of DMT on AI. An observational, population-based study, using the HemoBase registry, was performed including all newly diagnosed MDS patients between 2005 and 2017 in Friesland, a province of the Netherlands. All available information about treatment and transfusions, including transfusion dates, types, and treatment regimens, was collected from the electronic health records and laboratory systems. Follow-up occurred through March 2019. For our patient cohort, blood products were matched for AB0 and RhD, and transfused per the 'type and screen' policy (i.e. electronic matching of blood group phenotype between patient and donor). After a positive antibody screening, antibody identification and Rh/K phenotyping was performed and subsequent blood products were (cross)matched accordingly. The observation period was counted from first transfusion until last transfusion or first AI event. Univariate analyses and cumulative frequency distributions were performed to study possible risk factors and dynamics of AI. DMT was defined as hypomethylating agents, lenalidomide, chemotherapy and monoclonal antibodies. The effect of DMT as a temporary risk period on the risk of AI was estimated with incidence rates, relative risks (RR) and hazard ratios (HR) using a cox regression analysis. Follow-up was limited to 24 months for the cox regression analysis to avoid possible bias by survival differences. Statistical analyses were performed using IBM SPSS 24 and SAS 9.4. Out of 292 MDS patients, 236 patients received transfusions and were included in this study, covering 463 years of follow-up. AI occurred in 24 patients (10%). AI occurred mostly in the beginning of the observation period: Eighteen patients (75%) were alloimmunized after receiving 20 units of RBCs, whereas 22 patients (92%) showed AI after 45 units of RBCs (Figure 1). We found no significant risk factors for AI in MDS patients at baseline. DMT was given to 67 patients (28%) during the observation period. Patients on DMT received more RBC transfusions than patients that did not receive DMT (median of 33 (range: 3-154) and 11 (range: 0-322) RBC units respectively, p<0,001). Four AI events (6%) occurred in patients on DMT and 20 AI events (12%) occurred in patients not on DMT. Cox regression analysis of the first 24 months of follow-up showed an HR of 0.30 (95% CI: 0.07-1.31; p=0.11). The incidence rates per 100 person-years were 3.19 and 5.92 respectively. The corresponding RR was 0.54 (95% CI: 0.16-1.48; p=0.26). Based on our results, we conclude that the incidence of AI in an unselected, real world MDS population receiving RBC transfusions is 10% and predominantly occurred in the beginning of follow-up. Risk factors for AI at baseline could not be identified. Our data showed that patients on DMT received significantly more RBC transfusions but were less susceptible to AI. Therefore, extensive matching of blood products may not be necessary for patients on DMT. Larger studies are needed to confirm the protective effect of DMT on AI.

Abstract Background: Osteosarcoma is the most common primary malignant bone tumor. The current study was conducted to describe the general condition of patients with primary osteosarcoma in a single cancer center in Tianjin, China and to investigate the associated factors in osteosarcoma patients with lung metastasis. Methods: From February 2009 to October 2020, patients from Tianjin Medical University Cancer Institute and Hospital, China were retrospectively analyzed. The Kaplan–Meier method was used to evaluate the overall survival of osteosarcoma patients. Prognostic factors of patients with osteosarcoma were identified by the Cox proportional hazard regression analysis. Risk factor of lung metastasis in osteosarcoma were investigated by the logistic regression model. Results: A total of 203 patients were involved and 150 patients were successfully followed up for survival status. The 5-year survival rate of osteo-sarcoma patients was 70.0%. Surgery, bone and lung metastasis were the significant prognostic factors in multivariable Cox regression analysis. Twenty-one (10.3%) patients showed lung metastasis at the diagnosis of osteosarcoma and 67 (33%) lung metastases during the later course. T3 stage (OR=11.415, 95%CI 1.362-95.677, P=0.025) and synchronous bone metastasis (OR=6.437, 95%CI 1.69-24.51, P=0.006) were risk factors of synchronous lung metastasis occurrence. Good necrosis (≥90%, OR=0.097, 95%CI 0.028-0.332, P=0.000) and elevated Ki-67 (≥50%, OR=4.529, 95%CI 1.241-16.524, P=0.022) were proved to be significantly associated with metachronous lung metastasis occurrence. Conclusion: The overall survival, prognostic factors and risk factors for lung metastasis in this single center provided insight about osteosarcoma management.
