Incidence, patterns of progression and outcomes of melanoma brain metastasis (MBM) during programmed-death 1 inhibitor (PD1i) therapy.

9532 Background: MBM are common in patients (pts) with metastatic melanoma (MM) and represent a frequent site of treatment failure with current therapies. Little is known, however, about the incidence, patterns of progression and outcomes of MBM pts treated with PD1i and in conjunction with central nervous system (CNS) focused therapy. Methods: Outcomes of mm pts treated with PD1i at MD Anderson from 01/12 to 07/16 were reviewed. The association between clinical variables and development of MBM and overall survival (OS) were assessed using logistic regression and Cox regression analyses. Results: We identified 324 mm pts, including 77 pts (24%) who had MBM prior to first dose of PD1i. Median follow-up from start of therapy was 16.3 months, median OS for pts without MBM at the start of PD1i 3.37 years, as compared to 2.85 years in pts with prior MBM (p = 0.268). Of the 247 pts without prior MBM, 64 (26%) developed MBM after exposure to PD1i. Of those, 21 pts (8.5%) developed MBM during therapy or within 30 days of discontinuation, with 12 (4.5%) having CNS-only progression, while 9 (3.6%) had both systemic and CNS progression. Pts with MBM prior to PD1i (n = 77) had CNS-only progression in 22 pts (28.6%) during therapy. Progression occurred in systemic and systemic plus CNS in 12 pts (15.6%) and 19 pts (24.7%), respectively. 24 pts (31.2%) had stable disease (SD). On multivariate analysis, pts with lung metastases (OR, 2.16; 95% CI, 1.25 - 3.78; p = 0.006) and NRAS-mutated tumors (OR, 2.17; 95% CI, 1.14 - 4.18; p = 0.02) were more likely to develop MBM; pts who had liver metastases at the start of PD1i (HR, 1.77; 95% CI, 1.09 - 2.87; p = 0.002) and those who developed MBM during PD1i (HR, 4.81; 95% CI, 3.00 - 7.71; p < 0.0001) had increased risk of death. Conclusions: We found a 26% incidence of MBM after PD1i exposure. Pts that develop MBM are still at higher risk of death despite advances in systemic and local CNS therapy. CNS-only progression was substantially higher in patients with MBM prior to PD1i, supporting a change in the natural history of the disease after PD1i. These findings support the use of CNS imaging to monitor disease during PD1i therapy.

Prognostic Implications

9049 Background: The natural history of BRAF and NRAS mutant (mut) melanoma (mel) has been described, but prognostic implications of KIT mut mel have not. Methods: We performed a single-center retrospective review of 180 patients (pts) enriched for mucosal, acral or chronic sun-damaged skin (CSD) mel and screened for KIT, BRAF, and NRAS mut from 4/07 - 4/10 as a part of a phase II imatinib study. Pt/disease characteristics were compared using the Kruskal-Wallis or Chi-square tests. Factors associated with outcomes were assessed by Kaplan-Meier methods and multivariable Cox regression. Results: Median age, 63.7 years; 54.4% male. Primary site: 40% mucosal, 29% acral, 22% CSD, 9% others. Mut rate: 18% KIT, 16% BRAF, 14% NRAS, 52% wild-type (wt). Pathologic subtype differed by genetic subgroup (p<.001) while age, gender, and stage did not (all p>0.05). 18/26 (69%) KIT mut pts received imatinib in the metastatic (met) setting; 6/18 received > 1 other KIT inhibitor. 3/25 (12%) BRAF mut pts received vemurafenib. 8/27 (30%) KIT mut, 4/27 (15%) BRAF mut, 6/20 (30%) NRAS mut, and 6/20 (30%) wt pts received ipilimumab. 149/180 (83%) pts developed mets at a median of 2.15 years (95% CI: 1.72, 2.72). Median follow-up (FU) of pts not developing mets was 3.91 yrs (range: 0.25, 14.34). Older age (HR: 1.02, 95% CI: 1.00, 1.03) and pathologic subtype (mucosal vs CSD HR: 1.70, 95% CI: 1.02, 2.84; non-CSD/unknown vs CSD HR: 2.05, 95% CI: 1.00, 4.21) were associated with increased risk of mets but not with time from mets to death. Of 149 pts who progressed, 123 (83%) died during FU. Median time from met to death was 1.21 years (95% CI: 0.91, 1.67). Median FU from time of mets among those alive at last FU was 2.53 yrs (range: 0.06, 6.85). Mut status including KIT mut was not associated with time to first met or time from met to death. Pts who received ipilimumab from time of first distant met had reduced risk of death (HR: 0.55, 95% CI: 0.36, 0.87) independent of mut status. No impact was observed with KIT inhibition. Conclusions: KIT mut status is not an independent predictor of time to mets or survival in pts with mets. Ipilimumab improved pt outcomes regardless of mut status. The lack of impact of KIT inhibitors is likely due to the heterogeneity of KIT mut in mel but does not preclude efficacy in appropriately selected pts.

ObjectiveHistory of cardiovascular diseases (CVDs) may influence the prognosis of patients hospitalised for COVID-19. We investigated whether patients with previous CVD have increased risk of death and major adverse cardiovascular event (MACE) when hospitalised for COVID-19.MethodsWe included 839 patients with COVID-19 hospitalised at the University Hospitals of Geneva. Demographic characteristics, medical history, laboratory values, ECG at admission and medications at admission were collected based on electronic medical records. The primary outcome was a composite of in-hospital mortality or MACE.ResultsMedian age was 67 years, 453 (54%) were males and 277 (33%) had history of CVD. In total, 152 (18%) died and 687 (82%) were discharged, including 72 (9%) who survived a MACE. Patients with previous CVD were more at risk of composite outcomes 141/277 (51%) compared with those without CVD 83/562 (15%) (OR=6.0 (95% CI 4.3 to 8.4), p<0.001). Multivariate analyses showed that history of CVD remained an independent risk factor of in-hospital death or MACE (OR=2.4; (95% CI 1.6 to 3.5)), as did age (OR for a 10-year increase=2.2 (95% CI 1.9 to 2.6)), male gender (OR=1.6 (95% CI 1.1 to 2.3)), chronic obstructive pulmonary disease (OR=2.1 (95% CI 1.0 to 4.2)) and lung infiltration associated with COVID-19 at CT scan (OR=1.9 (95% CI 1.2 to 3.0)). History of CVD (OR=2.9 (95% CI 1.7 to 5)), age (OR=2.5 (95% CI 2.0 to 3.2)), male gender (OR=1.6 (95% CI 0.98 to 2.6)) and elevated C reactive protein (CRP) levels on admission (OR for a 10 mg/L increase=1.1 (95% CI 1.1 to 1.2)) were independent risk factors for mortality.ConclusionHistory of CVD is associated with higher in-hospital mortality and MACE in hospitalised patients with COVID-19. Other factors associated with higher in-hospital mortality are older age, male sex and elevated CRP on admission.

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.

Introduction: The evidence that blood levels of the soluble receptor for advanced glycation end products (sRAGE) predict mortality in people with cardiovascular diseases (CVD) is inconsistent. To clarify this matter, we investigated if frailty status influences this association. Methods: We analysed data of 1,016 individuals (median age, 75 years) from 3 population-based European cohorts, enrolled in the FRAILOMIC project. Participants were stratified by history of CVD and frailty status. Mortality was recorded during 8 years of follow-up. Results: In adjusted Cox regression models, baseline serum sRAGE was positively associated with an increased risk of mortality in participants with CVD (HR 1.64, 95% CI 1.09–2.49, p = 0.019) but not in non-CVD. Within the CVD group, the risk of death was markedly enhanced in the frail subgroup (CVD-F, HR 1.97, 95% CI 1.18–3.29, p = 0.009), compared to the non-frail subgroup (CVD-NF, HR 1.50, 95% CI 0.71–3.15, p = 0.287). Kaplan-Meier analysis showed that the median survival time of CVD-F with high sRAGE (>1,554 pg/mL) was 2.9 years shorter than that of CVD-F with low sRAGE, whereas no survival difference was seen for CVD-NF. Area under the ROC curve analysis demonstrated that for CVD-F, addition of sRAGE to the prediction model increased its prognostic value. Conclusions: Frailty status influences the relationship between sRAGE and mortality in older adults with CVD. sRAGE could be used as a prognostic marker of mortality for these individuals, particularly if they are also frail.

BackgroundThe risk of death and complications after major trauma in patients with chronic kidney disease (CKD) is higher than in the general population, but whether this association holds true among Canadian trauma patients is unknown.ObjectivesTo characterize patients with CKD/receiving dialysis within a regional major trauma cohort and compare their outcomes with patients without CKD.MethodsAll major traumas requiring hospitalization between 2006 and 2017 were identified from a provincial trauma registry in Nova Scotia, Canada. Trauma patients with stage ≥3 CKD (estimated glomerular filtration rate <60 mL/min/1.73 m2) or receiving dialysis were identified by cross-referencing two regional databases for nephrology clinics and dialysis treatments. The primary outcome was in-hospital mortality; secondary outcomes included hospital/intensive care unit (ICU) length of stay (LOS) and ventilator-days. Cox regression was used to adjust for the effects of patient characteristics on in-hospital mortality.ResultsIn total, 6237 trauma patients were identified, of whom 4997 lived within the regional nephrology catchment area. CKD/dialysis trauma patients (n=101; 28 on dialysis) were older than patients without CKD (n=4896), with higher rates of hypertension, diabetes, and cardiovascular disease, and had increased risk of in-hospital mortality (31% vs 11%, p<0.001). No differences were observed in injury severity, ICU LOS, or ventilator-days. After adjustment for age, sex, and injury severity, the HR for in-hospital mortality was 1.90 (95% CI 1.33 to 2.70) for CKD/dialysis compared with patients without CKD.ConclusionIndependent of injury severity, patients without CKD/dialysis have significantly increased risk of in-hospital mortality after major trauma.

History Of Cancer

Background: Early cardiology involvement within 90 days of atrial fibrillation (AF) diagnosis is associated with greater likelihood of oral anticoagulant use and a reduced risk of stroke. Due to variation in cardiovascular care for patients with cancer, it is possible that a similar association does not exist for AF patients with cancer. Methods: We examined the association of early cardiology involvement with oral anticoagulation use among non-valvular AF patients with history of cancer (past or active), using data from 388,045 patients (mean age=68±15 years; 59% male) from the MarketScan database (2009-2014). ICD-9 codes in any position were used to identify cancer diagnosis prior to AF diagnosis. Provider specialty and filled anticoagulant prescriptions 3 months prior to and 6 months after AF diagnosis were obtained. Poisson regression models were used to compute the probability of an oral anticoagulant prescription fill and Cox regression was used to estimate the risk of stroke and major bleeding. Results: A total of 64,016 (17%) AF patients had a prior history of cancer. Cardiology involvement was less likely to occur among patients with history of cancer than those without (relative risk=0.92, 95% confidence interval (0.91, 0.93)). Similar differences were observed for cancers of the colon (0.90 (0.88, 0.92)), lung (0.76 (0.74, 0.78)), pancreas (0.74 (0.69, 0.80)), and hematologic system (0.88 (0.87, 0.90)), while no differences were observed for breast or prostate cancers. Patients with cancer were less likely to fill prescriptions for anticoagulants (0.89 (0.88, 0.90)) than those without cancer, and similar results were observed for cancers of the colon, lung, prostate, pancreas, and hematologic system. However, patients with cancer were more likely to fill prescriptions for anticoagulants (1.48 (1.45, 1.52)) if seen by a cardiology provider, regardless of cancer type. A reduced risk of stroke (hazard ratio=0.89 (0.81, 0.99)) was observed among all cancer patients who were seen by a cardiology provider than among those who were not, without an increased risk of bleeding (1.04 (0.95, 1.13)). Conclusion: AF patients with cancer were less likely to see a cardiologist, and less likely to fill an anticoagulant prescription than AF patients without cancer. However, cardiology involvement was associated with increased anticoagulant prescription fills and reduced risk of stroke, suggesting a beneficial role for cardiology providers to improve outcomes in AF patients with history of cancer.

259 Background: Exposure of Vietnam War Veterans to the defoliant Agent Orange (AO) has been linked to increased tumor stage of Veterans diagnosed with prostate cancer. However, information on the effect of exposure to treatment outcomes is lacking. The goal of this study was to evaluate oncologic outcomes in Veterans based on AO exposure history, accounting for known prognostic covariates not previously studied. Methods: United States military Veterans diagnosed with prostate adenocarcinoma born between the years 1930-1956 were identified from a large professionally curated institutional database. Evaluable patients had to have known AO exposure status, age, NCCN risk group, Charlson comorbidity score, smoking status, and whether initial therapy was surgical, radiation, or systemic. Risk of death, metastasis, and progression stratified by the type of initial therapy received was analyzed using Cox regression. Results: There were 70 AO exposed and 561 non-exposed Veterans identified, with a median follow-up of 10.0 years. AO exposure Veterans (AOeV) were significantly younger (64.0 versus 65.7 years, p=0.013) at diagnosis and presented at more advanced stages (e.g. Stage 4: 14.3% versus 2.5%) than non-exposed Veterans (non-AOeV). There was no difference for overall survival (HR=0.86, p=0.576, metastasis-free survival (HR=1.5, p=0.212), or progression-free survival (HR=0.67, p 0.060) between AOeV versus non-AOeV in analyses stratified by treatment received accounting for other prognostic covariates. Cigarette smoking was associated with a 2- 3-fold increased risk of death over those who quit or never smoked. Conclusions: Although AOeV do present at younger age and higher clinical stages than non-AOeV, the oncologic outcomes after accounting for treatments received and other prognostic covariates are similar. The implication is that AOeV are more likely to be recommended multimodality or systemic therapies at presentation.

Abstract Aims Cardiac troponins (cTn) have been reported to be predictors for adverse outcomes in atrial fibrillation (AF), patients, but their actual use is still unclear. To assess the factors associated with cTn testing in routine clinical practice and to evaluate the association of elevated levels of cTn with adverse outcomes in a large contemporary cohort of European AF patients. Methods and results Patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry were stratified into three groups according to cTn levels as (i) cTn not tested, (ii) cTn in range (≤99th percentile), and (iii) cTn elevated (>99th percentile). The composite outcome of any thromboembolism/any acute coronary syndrome (ACS)/cardiovascular (CV) death, defined as major adverse cardiovascular events (MACE) and all-cause death were the main endpoints. 10 445 (94.1%) AF patients were included in this analysis [median age 71 years, interquartile range (IQR): 63–77; males 59.7%]. cTn were tested in 2834 (27.1%). Overall, cTn was elevated in 904 (8.7%) and in-range in 1930 (18.5%) patients. Patients in whom cTn was tested tended to be younger (P < 0.001) and more frequently presenting with first detected AF and atypical AF-related symptoms (i.e. chest pain, dyspnoea, or syncope) (P < 0.001). On multivariable logistic regression analysis, female sex, in-hospital enrollment, first-detected AF, CV risk factors, history of coronary artery disease (CAD), and atypical AF symptoms were independently associated with cTn testing. After a median follow-up of 730 days (IQR: 692–749), 957 (9.7%) composite endpoints occurred while all-cause death was 9.5%. Kaplan–Meier analysis showed a higher cumulative risk for both outcomes in patients with elevated cTn levels (Figure) (Log Rank tests, P < 0.001). On adjusted Cox regression analysis, elevated levels of cTn were independently associated with a higher risk for MACE [hazard ratio (HR): 1.74, 95% confidence interval (CI): 1.40–2.16] and all-cause death (HR 1.45, 95% CI: 1.21–1.74). Elevated levels of cTn were independently associated with a higher occurrence of MACE, all-cause death, any ACS, CV death and hospital readmission even after the exclusion of patients with history of CAD, diagnosis of ACS at discharge, those who underwent coronary revascularization during the admission and/or who were treated with oral anticoagulants plus antiplatelet therapy. Conclusions Elevated cTn levels were independently associated with an increased risk of all-cause mortality and adverse CV events, even after exclusion of CAD patients. Clinical factors that might enhance the need to rule out CAD were associated with cTn testing.

Comorbidity Index

Abstract Despite improvements, mortality after allogeneic hematopoietic cell transplantation (HCT) for nonmalignant diseases remains a significant problem. We evaluated whether pre-HCT conditions defined by the HCT Comorbidity Index (HCT-CI) predict probability of posttransplant survival. Using the Center for International Blood and Marrow Transplant Research database, we identified 4083 patients with nonmalignant diseases transplanted between 2007 and 2014. Primary outcome was overall survival (OS) using the Kaplan-Meier method. Hazard ratios (HRs) were estimated by multivariable Cox regression models. Increasing HCT-CI scores translated to decreased 2-year OS of 82.7%, 80.3%, 74%, and 55.8% for patients with HCT-CI scores of 0, 1 to 2, 3 to 4, and ≥5, respectively, regardless of conditioning intensity. HCT-CI scores of 1 to 2 did not differ relative to scores of 0 (HR, 1.12 [95% CI, 0.93-1.34]), but HCT-CI of 3 to 4 and ≥5 posed significantly greater risks of mortality (HR, 1.33 [95% CI, 1.09-1.63]; and HR, 2.31 [95% CI, 1.79-2.96], respectively). The effect of HCT-CI differed by disease indication. Patients with acquired aplastic anemia, primary immune deficiencies, and congenital bone marrow failure syndromes with scores ≥3 had increased risk of death after HCT. However, higher HCT-CI scores among hemoglobinopathy patients did not increase mortality risk. In conclusion, this is the largest study to date reporting on patients with nonmalignant diseases demonstrating HCT-CI scores ≥3 that had inferior survival after HCT, except for patients with hemoglobinopathies. Our findings suggest that using the HCT-CI score, in addition to disease-specific factors, could be useful when developing treatment plans for nonmalignant diseases.

Abstract Introduction: Previous studies have shown that uninsured and Medicaid patients had higher morbidity and mortality due to limited access to healthcare. Disparities in cancer-related treatment and survival outcome by different insurance have been well established (Celie et al. J Surg Oncol.,2017). There are approximately 8,260 newly diagnosed HL cases in the US yearly (Master et al. Anticancer Res.2017). Therefore, we aim to investigate the variation of survival outcome and insurance status among HL patients. Methods: We extracted data from the US National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) 18 program. HL patients who were diagnosed from 2007-2014 were included. Demographic information including age, sex, race, annual household income, education and insurance were also collected. Insurance includes uninsured, insured and any Medicaid. Race/ethnicity includes white, black and other (including American Indian/AK native, Asian/Pacific Islander). HL is categorized by using International Classification of Disease for Oncology (ICD-O-3) into classical HL NOS (CHL NOS), nodular lymphocyte predominant HL (NLP), lymphocyte rich (LR), mixed cellularity (MC), lymphocyte depleted (LD), and nodular sclerosis (NS). Treatment modality included RT alone, CT alone, RT and CT combined, and no RT or CT. Survival time was estimated by using the date of diagnosis and one of the following dates: date of death, date last known to be alive or date of the study cutoff (December 31, 2014). Chi-square test and multivariate Cox regression were performed by using SAS 9.4 (SAS Institute Inc., Cary, NC, USA). Exclusion criteria include: 1) patients with unknown or unspecified race; 2) patients who survived less than 6 months because time of radiotherapy/chemotherapy was not known to the time of diagnosis; 3) patients with any other type of cancer prior to the diagnosis of HL; 4) patients with second or later primaries, and who were not actively followed. Results: A total of 14.286 HL patients were included in the analysis. Table 1 indicates the insurance status and demographic and tumor characteristics among HL patients diagnosed between 2007 and 2014. Patients with black race, male sex, and B symptoms were more likely to be uninsured and on any Medicaid compared to other races, female sex and without B symptoms (p<0.01). As stage of disease increased, the percentage of insured patients decreased from 82.0% to 71.7%, (p<0.01). As with year of diagnosis advanced, the percentage of uninsured did not appear to be changed however the proportion of both those with insurance and any Medicaid decreased slightly by 2.4% (p<0.01). Those who received RT only were most likely to have insurance (89.6%) followed by combination modality (80.1%). As expected, uninsured status was associated with lower income and education level (p<0.01). Table 2 shows the insurance and hazard ratio among HL patients by year of diagnosis adjusting for race, sex, histology type, income, education, and year of diagnosis. Any Medicaid patients had the highest HR of death from 2007-2010 compared to insured patients. Without insurance was also associated with increased risk of death but only significant in 2008, HR=2.26, 95% CI (1.35, 3.80). The survival outcomes comparing different insurance status by age groups (<=29 and 30-64) were demonstrated in Kaplan-Meier Curve. In the age 29 or less group, insured patient showed has the best survival outcome followed by any Medicaid and then the uninsured. In the age 30-64 group, Medicaid patients had the worst survival outcome compared to those with or without insurance. Conclusion: Insurance status is one of the most important contributors of health disparity, especially in malignancy given the significant financial toxicity of therapies. We found that the proportion of the uninsured was trending up before the Affordable Care Act (ACA). Regarding the HL outcome, insured patients had the best survival across all age groups even though not significantly while Medicaid patients had the worst outcomes in almost all age groups, even worse than the uninsured after adjusting for the disease stage at diagnosis and sociodemographic factors. It would be of interest to explore the reason behind Medicaid patients' relatively poor outcomes. Future studies may also investigate how ACA, Medicaid expansion, and the possible upcoming republican healthcare reform influence HL outcome.
