Abstract
BACKGROUND Real-world studies assessing the comparative effectiveness of biologic or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) as first-line targeted therapy are scarce. We analyzed the real-world persistence and effectiveness of etanercept (ETN), adalimumab (ADA), and Janus kinase inhibitors (JAKis) as first-line therapy in b/tsDMARD-naïve patients with rheumatoid arthritis (RA). METHODS Adults (≥ 18 years) enrolled in the CorEvitas RA Registry and initiating ETN, ADA, or a JAKi (alone or in combination with csDMARDs) between November 2012 and June 2021 were included if they had 6 and/or 12 months' follow-up. Treatment persistence and effectiveness outcomes including the change in Clinical Disease Activity Index (CDAI) and patient-reported outcomes (PROs) were evaluated at follow-up, adjusting for covariates using linear and logistic regression models. An exploratory analysis for patients on monotherapy was also conducted. RESULTS Of 1059 ETN, 1327 ADA, and 581 JAKi initiators; 803 ETN, 984 ADA, and 361 JAKi initiators had 6 months' follow-up. JAKi initiators were older and had a relatively longer disease duration than ETN or ADA initiators (mean age: 61.3 vs 54.5 and 55.5 years; mean duration of RA: 8.1 vs 5.7 and 5.6 years). Unadjusted mean improvements in CDAI and PROs were similar between the groups at 6 months, except the proportion achieving LDA, remission, and MCID in CDAI, which were numerically higher in the ETN and ADA groups vs JAKi group (LDA: 43.4% and 41.9% vs 32.5%; remission: 18.2% and 15.1% vs 11.5%; MCID: 46.5% and 47.8% vs 38.0%). Adjusted effectiveness results did not reveal statistically significant differences between treatment groups at 6 months, with an exception in MCID (odds ratio [95% CI] for JAKi vs ETN: 0.65 [0.43-0.98]). At 6 months, 68.2% of ETN, 68.5% of ADA, and 66.5% of JAKi initiators remained on therapy. The findings at 12 months' follow-up and sensitivity analysis among monotherapy initiators also showed no differences in effectiveness outcomes between the groups. CONCLUSIONS This analysis of real-world data from the CorEvitas RA Registry did not show differences in clinical effectiveness and treatment persistence rates in b/tsDMARD-naïve patients initiating ETN, ADA, or JAKi as first-line targeted therapy either alone or in combination with csDMARDs.

Abstract
OBJECTIVE Real-world studies assessing treatment response by psoriatic arthritis (PsA) domains are limited. This study aimed to describe the patient characteristics, frequency and combinations of disease domains, disease activity, and patient-reported outcomes (PROs) by PsA domains in patients who initiated treatment with a tumor necrosis factor inhibitor (TNFi) or interleukin-17 inhibitor (IL-17i). METHODS Adults with PsA who initiated treatment with a TNFi or an IL-17i between January 2013 and January 2021 and had a 6 (±3)-month follow-up were included. The prevalence of PsA domains, the most common domain combinations, treatment persistence, and unadjusted change in disease activity and PROs from baseline to 6 months for each PsA domain were summarized descriptively. RESULTS Of the 1005 eligible patients, 63% were receiving TNFi and 37% were receiving IL-17i. Forty percent of TNFi and 14% of IL-17i initiators received these treatments as first-line therapy. Peripheral arthritis and skin disease were the most common PsA domains identified in 86% and 82% of patients, respectively, and the triad of peripheral arthritis, skin disease, and nail psoriasis was the most common domain combination observed in 14% of patients. More than two thirds (68%) of patients remained on therapy at 6 months' follow-up. Improvements in disease activity and PROs were observed across all PsA domains in those receiving TNFi or IL-17i. CONCLUSION This real-world analysis highlights the heterogeneity in domain presentation; therefore, assessing all PsA domains is important for optimal disease management. Improvements in outcomes across all PsA domains demonstrate the effectiveness of TNFi and IL-17i in diverse patient groups exhibiting different phenotypes of PsA.

Abstract
OBJECTIVE Etanercept is commonly used to treat juvenile idiopathic arthritis, including juvenile psoriatic arthritis (JPsA); however, information on etanercept's safety and effectiveness in clinical practice is limited. We used data from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry to evaluate etanercept's safety and effectiveness in JPsA in clinical practice. METHODS We analysed safety and effectiveness data for paediatric patients enrolled in the CARRA Registry who had a JPsA diagnosis and had used etanercept. Safety was assessed by calculating rates of prespecified adverse events of special interest (AESIs) and serious adverse events (SAEs). Effectiveness was assessed by a variety of disease activity measures. RESULTS Overall, 226 patients had JPsA and received etanercept; 191 met criteria for safety analysis and 43 met criteria for effectiveness analysis. AESI and SAE incidence rates were low. There were five events: three uveitis, one new-onset neuropathy and one malignancy. Incidence rates were 0.55 (95% CI: 0.18, 1.69), 0.18 (95% CI: 0.03, 1.29) and 0.13 (95% CI: 0.02, 0.09) per 100 patient-years for uveitis, neuropathy and malignancy, respectively. Etanercept showed effectiveness for JPsA treatment; 7 of 15 (46.7%) had an American College of Rheumatology-Pediatric Response 90, 9 of 25 (36.0%) had a clinical Juvenile Arthritis Disease Activity Score 10-joint ≤1.1 and 14 of 27 (51.9%) had clinically inactive disease at the 6-month follow-up. CONCLUSION Data in the CARRA Registry showed that etanercept treatment was safe in treating children with JPsA, with low AESIs and SAEs. Etanercept was also effective, even when assessed in a small sample size.

Abstract
BACKGROUND/PURPOSE Tumor necrosis factor inhibitors (TNFi) may have a direct benefit on cardiovascular (CV) disease beyond reducing rheumatoid arthritis (RA) disease activity measured by the Clinical Disease Activity Index (CDAI). METHODS We compared TNFi initiators and methotrexate (MTX) monotherapy initiators from the CorEvitas RA registry. Two approaches to the "direct effect" of TNFi beyond CDAI were used. In the natural direct effect (NDE) analysis, the potential CV benefit of TNFi was partitioned into NDE and the natural indirect effect (NIE) mediated by CDAI during the first 6 months. We also estimated the controlled direct effects (CDE), corresponding to the direct benefit of TNFi when CDAI trajectories were hypothetically equalized between the initiators of TNFi and MTX monotherapy at a constant value. Estimates were given on the hazard ratio scale. RESULTS We identified 5764 initiators of TNFi and 3588 initiators of MTX monotherapy. TNFi initiators were younger (58 vs. 64 years) with a shorter disease duration. Our total effect estimates (TNFi vs. MTX [reference]) were protective in direction (0.76-0.91). The NDE estimate was 0.76 [95% confidence interval (CI) 0.59, 0.98], whereas the NIE estimate was 1.00 [95%CI 1.00, 1.00]. In the CDE analyses accounting for longitudinal CDAI, the CDE estimates was 1.27 [95%CI 0.60, 2.69]. CONCLUSIONS We could not convincingly demonstrate a direct benefit of TNFi outside its impact on CDAI. At present, the emphasis should be on the stringent control of RA disease activity, a known important CV risk factor, regardless of medication choice.

Abstract
BackgroundOngoing debate exists regarding the optimal sequence of tumor necrosis factor inhibitors and Janus kinase inhibitors (JAKis) in patients with rheumatoid arthritis (RA) as first-line biologic or targeted synthetic disease-modifying antirheumatic drug (b/tsDMARD) therapy following conventional therapies.ObjectivesTo describe baseline characteristics, effectiveness, persistency, and treatment patterns among first-line b/tsDMARD-naive initiators of etanercept (ETN), adalimumab (ADA), or JAKis (tofacitinib, baricitinib, and upadacitinib).MethodsData on patients who initiated b/tsDMARD from 11/2012 to 6/2021 were obtained from the CorEvitas RA Registry, a prospective, multicenter, observational, disease-based registry. Patients ≥18 years with rheumatologist-diagnosed RA and 6- and/or 12-months’ (M) follow-up were included. We report descriptive statistics at baseline, persistency on therapy, escalation/de-escalation of therapy, details on patterns of drug switching, and effectiveness outcomes using regression models adjusted for baseline covariates (demographic/socioeconomic/lifestyle characteristics, comorbidities, medication history, disease activity, and patient-reported outcomes). Outcomes were evaluated at 6M and 12M follow-up.ResultsFirst-line initiators of ETN, ADA, and JAKis with baseline and follow-up visits were identified: 803, 984, and 361 patients at 6M, respectively; 589, 749, and 264 patients at 12M, respectively. Baseline characteristics were similar among ETN, ADA, and JAKi initiators with the exception of disease duration, which was longer among first-line JAKi initiators (mean, 8.6 y) versus ETN (5.9 y) and ADA (5.8 y) initiators. Unadjusted mean improvement in Clinical Disease Activity Index (CDAI) was generally similar between groups at 6M and 12M (Table 1). Adjusted effectiveness results were similar at 6M and 12M (Figure 1). At 6M, 68% of ETN, 69% of ADA, and 67% of JAKi initiators remained on the same therapy; at 12M, 53% of ETN, 57% of ADA, and 57% of JAKi initiators remained on the same therapy. The frequency of switching to another b/tsDMARD was similar across initiators.Table 1.Patient Description at Time of Initiation and Unadjusted Disease Activity ResultsETNADAJAKisAge, years54.4 (12.8)55.5 (12.1)60.9 (12.5)Female, n (%)666 (77)843 (76)303 (77)BMI, kg/m230.4 (7.6)31.3 (7.9)30.8 (7.6)Duration of RA, years5.9 (7.6)5.8 (7.3)8.6 (10.0)BL disease activitya CDAI19.9 (14.3)18.9 (12.7)18.8 (13.2) mHAQ0.5 (0.5)0.5 (0.5)0.5 (0.5) Patient painb48.0 (28.8)49.2 (28.5)45.2 (29.2)Disease activity decrease from BL at 6M CDAI6.9 (13.6)6.4 (12.1)4.7 (12.3) mHAQ0.1 (0.4)0.1 (0.4)0.1 (0.4) Patient painb9.7 (30.2)10.6 (28.4)8.9 (29.5)Disease activity decrease from BL at 12M CDAI7.4 (13.5)6.1 (13.0)5.1 (13.0) mHAQ0.1 (0.4)0.1 (0.4)0.1 (0.4) Patient painb8.8 (29.7)8.7 (30.1)7.5 (28.6)Achievement of LDAc, % 6M43.441.932.5 12M41.039.638.3aBaseline for combined population with 6M and 12M follow-up. b(range: 0–100). cCDAI ≤10 among those with moderate or high disease activity at baseline.Data are mean (SD) unless otherwise specified.ADA, adalimumab; BL, baseline; CDAI, Clinical Disease Activity Index; ETN, etanercept; JAKis, Janus kinase inhibitors; LDA, low disease activity; M, months; mHAQ, modified Health Assessment Questionnaire; RA, rheumatoid arthritis; SD, standard deviation.ConclusionIn this real-world study in patients initiating first-line b/tsDMARD therapy with ETN, ADA, or JAKis, we did not observe differences in clinical effectiveness/patient-reported outcomes and treatment persistency at 6M and12M after treatment initiation.AcknowledgementsThis study is sponsored by CorEvitas, LLC.

Abstract
BackgroundPsoriatic arthritis (PsA) is a burdensome, chronic disease that can impact patient functionality and quality of life. Real-world data are limited regarding the most common disease domain combinations in patients with PsA receiving biologic disease-modifying anti-rheumatic drugs.ObjectivesThe objective of this study was to describe PsA disease domain frequency, the most common disease domain combinations of PsA manifestations, and pairwise disease domain prevalence in patients initiating treatment with tumor necrosis factor inhibitors (TNFis) or interleukin-17 (IL-17) inhibitors.MethodsThe CorEvitas PsA/Spondyloarthritis (SpA) Registry is a prospective, observational registry for patients with PsA or SpA under the care of a rheumatologist. The current analysis included adults with PsA who initiated treatment with a TNFi (adalimumab, etanercept, certolizumab pegol, infliximab, golimumab), etanercept (ETN; independent exploratory evaluation as a subset of the TNFi group), or an IL-17 inhibitor (ixekizumab, secukinumab) from January 2013 through December 2020. Baseline disease characteristics among the total population and by therapy group were examined for 6 PsA domains, including enthesitis (ET), dactylitis (DA), peripheral arthritis (PA), nail psoriasis (NP), axial PsA (AX), and skin disease (SD). The top 5 most common domain combinations and frequency of other concomitant disease domains within each domain subpopulation are presented.ResultsAmong 1005 patients initiating treatment for PsA (mean age, 52.9 years; 57% female, 90% white), the prevalence of disease domains was PA (86%), SD (82%), NP (57%), ET (38%), DA (23%), and AX (20%); these proportions were similar among the therapy groups. The frequency of high skin disease (body surface area [BSA] ≥10%) at baseline was highest in IL-17 initiators (23% vs 16% for TNFi and 9% for ETN). TNFi (40%) and ETN (48%) were more frequently observed as first-line therapy compared with IL-17 inhibitors (14%). The most common disease domain combination overall (14%) was PA, NP, and SD; frequency of the top 3 most common domain combinations were similar among therapy groups (Table 1). Overall, PA and SD were the most common concomitant disease domains observed within each PsA disease domain subpopulation (Figure 1). Results were similar by therapy group (data not shown).Table 1.Most common PsA domain combinations overall and by therapyDomain Combination Ranking by Frequency, n (%)Overall (N=1005)TNFia (n=631)ETN (n=112)IL-17 (n=374)#1PA, NP, SD 138 (14)PA, NP, SD 91 (14)PA, SD 17 (15)PA, NP, SD 47 (13)#2PA, SD 122 (12)PA, SD 84 (13)ET, PA, NP, SD 13 (12)ET, PA, NP, SD 41 (11)#3ET, PA, NP, SD 95 (9)ET, PA, NP, SD 54 (9)PA, NP, SD 12 (11)PA, SD 38 (10)#4ET, PA, SD 64 (6)DA, PA, NP, SD 38 (6)SD 7 (6)ET, PA, SD 33 (9)#5DA, PA, NP, SD 61 (6)ET, PA, SD 31 (5)ET, PA, NP, AX, SD 6 (5)ET, PA, NP, AX, SD 24 (6)Matching domain combinations are shaded across each therapy group.ET, enthesitis; DA, dactylitis; PA, peripheral arthritis; NP, nail psoriasis; AX, axial PsA; SD, skin disease; TNFi, tumor necrosis factor inhibitors; ETN, etanercept; IL-17, interleukin-17 inhibitors.aTNFi includes ETN initiators.Figure 1.ConclusionThe most common disease domains and domain combinations were similar among initiators of TNFis, ETN, and IL-17s.

Abstract
Objective It is unknown how the relationship between disease activity in rheumatoid arthritis (RA) and cardiovascular (CV) events may change over time. We examined the potentially time‐varying association of RA disease activity to CV events. Methods We used the CorEvitas prevalent RA registry. The Clinical Disease Activity Index (CDAI) score category, averaged within each 6‐month window since enrollment, was the exposure, and the outcome was major adverse CV events (MACEs). We used marginal structural models to estimate the hazard ratio (HR), comparing each CDAI score category with remission, allowing for differential association over time. We predicted MACE‐free survival under several CDAI score scenarios. Results We found 44,816 eligible patients (77% female; mean age 58 years) with a crude event rate of 5.3/1000 person‐years (median follow‐up 3.4 years). The strongest association between higher CDAI score and MACEs was observed during the first 6 months of enrollment (HR for CDAI score low 2.29 [95% CI: 1.21‐4.36], moderate 2.81 [95% CI: 1.46‐5.43], and high 2.99 [95% CI: 1.48‐6.02]). These estimates gradually diminished; by year 5, the HRs were 1.00 (95% CI: 0.49‐2.05) for low, 1.18 (95% CI: 0.51‐2.71) for moderate, and 1.04 (95% CI: 0.45‐2.40) for high CDAI score. Predicted MACE‐free survival suggested a potential decrease in MACEs with a hypothetical earlier transition to remission. Conclusion The association of higher disease activity with CV events may be stronger earlier in the disease course of RA. Interventional studies may be warranted to precisely determine the effect of disease activity suppression on CV events in RA.

Abstract
Background Understanding the evolving treatment patterns in patients with rheumatoid arthritis (RA) is important for rheumatologists to make the best practice decisions and optimize treatment. Here, we describe treatment patterns among patients newly initiated on biologic and/or nonbiologic RA therapy over time after enrollment in the US Corrona RA registry. Methods This was a retrospective, cohort study of adult patients with RA enrolled in the Corrona RA registry. Patients were included in this study if they initiated therapy with conventional synthetic disease-modifying antirheumatic drug (csDMARD) monotherapy, TNF inhibitor (TNFi) monotherapy, other (non-TNFi) biologic monotherapy, or combination therapy (index therapy); initiated therapy between January 1, 2004, and December 31, 2015 (index date), after enrollment in the Corrona RA registry; had at least 6 months of follow-up time after the index date; and had at least one follow-up visit. Time periods of interest were based on the year of index therapy initiation: 2004–2007, 2008–2011, and 2012–2015. Results This study included 8027 patients. csDMARD monotherapy and TNFi + csDMARD combination therapy were the most common index therapies in the registry (39.9% and 44.9%, respectively, in the 2004–2007 period; 38.6% and 38.2%, respectively, in the 2008–2011 period; and 35.2% for both in the 2012–2015 period). At therapy initiation, a higher proportion of patients who initiated other biologics, whether as monotherapies (54.0%) or in combination with csDMARD (49.9%), had high disease activity than those who initiated csDMARD monotherapy (28.4%). For 2012–2015 vs 2004–2007 and 2008–2011 periods, persistence on a given therapy appeared to decrease for the TNFi monotherapy cohort (48.2% vs 64.3% and 52.4%) and other biologic monotherapy cohort (52.3% vs 71.4% and 54.5%) over 12 months; switching from one therapy to another was common in the Corrona RA registry. Conclusions Increased switching from one therapy to another and decreased time on a given therapy was observed in the Corrona RA registry in the 2012–2015 period. This observation is most likely due to the increased availability of additional treatment options and/or the change in clinical focus, particularly the emphasis on achievement of treat-to-target goals of remission or low disease activity along with more aggressive treatment.

Abstract
BACKGROUND We aimed to characterize etanercept (ETN) use in juvenile idiopathic arthritis (JIA) patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry. METHODS The CARRA Registry is a convenience cohort of patients with paediatric onset rheumatic diseases, including JIA. JIA patients treated with ETN for whom the month and year of ETN initiation were available were included. Patterns of ETN and methotrexate (MTX) use were categorized as follows: combination therapy (ETN and MTX started concurrently), step-up therapy (MTX started first and ETN added later), switchers (MTX started and then stopped when or before ETN started), MTX add-on (ETN started first and MTX added later), and ETN only (no MTX use). Data were described using parametric and non-parametric statistics as appropriate. RESULTS Two thousand thirty-two of the five thousand six hundred forty-one patients with JIA met inclusion criteria (74% female, median age at diagnosis 6.0 years [interquartile range 2.0, 11.0]. Most patients (66.9%) were treated with a non-biologic disease modifying anti-rheumatic drug (DMARD), primarily MTX, prior to ETN. There was significant variability in patterns of MTX use prior to starting ETN. Step-up therapy was the most common approach. Only 34.0% of persistent oligoarticular JIA patients continued treatment with a non-biologic DMARD 3 months or more after ETN initiation. ETN persistence overall was 66.3, 49.4, and 37.3% at 24, 36 and 48 months respectively. ETN persistence among spondyloarthritis patients (enthesitis related arthritis and psoriatic JIA) varied by MTX initiation pattern, with higher ETN persistence rates in those who initiated combination therapy (68.9%) and switchers/ETN only (73.3%) patients compared to step-up (65.4%) and MTX add-on (51.1%) therapy. CONCLUSION This study characterizes contemporary patterns of ETN use in the CARRA Registry. Treatment was largely in keeping with American College of Rheumatology guidelines.

Abstract
Background:Rheumatoid arthritis (RA) patients have an increased risk of cardiovascular (CV) events not fully explained by traditional CV risk factors. The relationship between fluctuating inflammation due to RA disease activity and CV events is of interest.Objectives:To examine the influence of time-varying disease activity on the subsequent risks of CV disease.Methods:We followed patients from a large US registry of clinically diagnosed RA patients, starting at their first visit with a Clinical Disease Activity Index (CDAI) through the end of follow-up or first CV event. Exposure of interest was disease activity measured by categorical CDAI (high, moderate, low, and remission) averaged within each 6-month window. The outcome of interest was major adverse CV events (MACE) defined as non-fatal myocardial infarction, non-fatal stroke (excluding transient ischemic attacks), and CV death. For baseline confounders we considered age, gender, race, disease duration, Health Assessment Questionnaire, hypertension, diabetes, hyperlipidemia, family history of premature (age<50) CV events, and RF/ACPA seropositivity. For time-varying variables we considered tumor necrosis factor inhibitor (TNFi), non-TNFi biologic, methotrexate, oral glucocorticoid, non-steroidal anti-inflammatory drugs, statin, and aspirin use. We used the marginal structural model (MSM) framework to examine the impact of CDAI at each 6-month interval on MACE. We estimated time-varying hazard ratios (HRs) comparing high CDAI during follow-up to CDAI remission. Several predicted survival curves were constructed under different hypothetical CDAI scenarios, such as early and late transition to CDAI remission.Results:40,721 patients were eligible for our analyses. 77% were female and 84% were Caucasian. The mean age was 58 (SD 13) years with mean disease duration of 8.8 (median 5) years. Mean CDAI at their first registry visit was 14 (SD 13; remission 19%, low 31%, moderate 28%, and high 22%). Other baseline characteristics include: 41% current/former smokers, 31.5% with hypertension, 8.6% with diabetes, 18% with hyperlipidemia, and 52% seropositive. The average follow-up duration after baseline was 4.4 (median 3.3; max. 17.6) years. The crude event count of MACE was 1,050 events / 180,402 person-years.In the MSM analysis, the average HRs, assuming a constant HR, were 1.31 [0.90, 1.90] for low, 1.46 [1.01, 2.10] for moderate, and 1.43 [0.89, 2.31] for high CDAI disease activity categories during each 6-month interval. When approximating time-varying HR with linear trends, the highest estimates during the first 6 months of follow up were 1.61 [0.93, 2.77] for low CDAI, 1.97 [1.13, 3.43] for moderate CDAI, and 2.11 [1.13, 3.96] for high CDAI. These HRs gradually diminished during the follow up (Table). When we constructed hypothetical survival curves with transition to CDAI remission at different time points, earlier transition to CDAI remission was related to better event-free survival (Figure).Table 1.Time-varying hazard ratio estimates [95% confidence intervals] by duration in studyDisease activity measured by CDAIYearRemissionLowModerateHigh0.51.00 [ref]1.61 [0.93, 2.77]1.97 [1.13, 3.43]2.11 [1.13, 3.96]11.00 [ref]1.54 [0.97, 2.44]1.85 [1.17, 2.93]1.94 [1.13, 3.31]21.00 [ref]1.42 [1.00, 2.01]1.63 [1.16, 2.29]1.62 [1.04, 2.54]31.00 [ref]1.31 [0.90, 1.90]1.43 [0.97, 2.11]1.36 [0.80, 2.31]41.00 [ref]1.20 [0.72, 2.02]1.26 [0.72, 2.21]1.14 [0.55, 2.36]51.00 [ref]1.11 [0.54, 2.26]1.11 [0.51, 2.42]0.96 [0.36, 2.53]Figure 1.MACE-free survival curves under hypothetical CDAI scenariosConclusion:High and moderate CDAI were associated with higher hazard of MACE during the earlier period of follow-up, but the increased hazard diminished over time.

Abstract
OBJECTIVE To describe characteristics of children with enthesitis-related arthritis (ERA) and juvenile psoriatic arthritis (PsA) who were enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) registry. METHODS All children with ERA and those with juvenile PsA were identified. Demographic characteristics, clinical characteristics, and treatments were described. The children with sacroiliitis and those without sacroiliitis were compared. In the children with sacroiliitis, the first visit with clinically active sacroiliitis (which came first in 72% of cases) was compared to the first visit without clinically active sacroiliitis. RESULTS A total of 902 children with ERA or juvenile PsA were identified. Children with ERA were older at diagnosis (ages 10.8 years versus 8.2 years; P < 0.01) and were more likely to be male (56% versus 38%; P < 0.01). Polyarticular involvement was reported in 57% of children with ERA and in 72% of those with juvenile PsA. Of the children tested, HLA-B27 was positive in 38% of those in the ERA group and in 12% of those in the juvenile PsA group. At least 1 biologic was taken by 72% of those with ERA and 64% of those with juvenile PsA. Sacroiliitis (diagnosed clinically and/or by imaging) was reported in 28% of the children (40% of those with ERA and 12% of those with juvenile PsA). Of these, 54% of the children were female, 36% were HLA-B27 positive, and 81% took at least 1 biologic. In children with sacroiliitis, scores according to the physician global assessment of disease activity, parent/patient global assessment of well-being, and clinical Juvenile Arthritis Disease Activity Score 10 were all significantly worse at the first visit with clinically active sacroiliitis versus the first visit without active sacroiliitis. CONCLUSION In this registry, there are more than 900 children with ERA or juvenile PsA. There was high biologic use in this population, especially in those with sacroiliitis. Further, there was equal sex representation in those children with sacroiliitis.

Abstract
Objective The purpose of this study was to evaluate maintenance of remission/low disease activity (LDA) in patients with rheumatoid arthritis (RA) who achieved remission/LDA with etanercept (ETN) plus a conventional synthetic disease‐modifying antirheumatic drug (csDMARD) and to compare patients who discontinued csDMARD to receive ETN monotherapy (Mono) with those remaining on combination therapy (Combo). Methods Patients from the Corrona RA registry between October 1, 2001, and August 31, 2017, were eligible. The index date for the Mono cohort was the csDMARD discontinuation date; the index visit for the Combo cohort was estimated from time between ETN initiation and csDMARD discontinuation in the Mono cohort. The main outcome calculated was maintenance of remission/LDA. Patients were censored if they switched to or added a biologic DMARD, discontinued ETN, when a csDMARD was reintroduced (Mono), or if methotrexate increased more than 5 mg/d (Combo). Trimming was used to balance demographic and clinical characteristics between groups. Cox regression models were adjusted for the remaining differences across groups. Results We identified 182 Mono and 403 Combo patients; 120 Mono and 207 Combo patients remained after trimming. Most patients (approximately 80%) were biologic medication–naive before initiating ETN. At 24 months postindex, modeled percentages of patients remaining in remission/LDA were 75% for Mono and 86% for Combo (overall adjusted P = 0.057). More patients were censored for therapy change in Mono than in Combo groups (37% versus 5%), largely due to reintroduction of csDMARDs in the Mono group. Conclusion Many patients with RA who achieved remission/LDA on combination therapy maintained remission/LDA with ETN monotherapy for 2 years after csDMARD discontinuation. ETN monotherapy may be a viable option for patients who discontinue csDMARDs after achieving LDA/remission.

Abstract
Background:Methotrexate (MTX) is frequently used in patients with rheumatoid arthritis (RA) or psoriatic arthritis (PsA) because of its beneficial effects in both populations1-3. Despite the well-known benefits of MTX, it is associated with a number of potential side effects4-6These include nausea and fatigue, are often temporally related to the timing of weekly MTX administration, and can be severe. The combined patient-reported side effects, along with potential of long-term toxicity, may make use of MTX more burdensome. Currently, there is a gap in patient-centered studies that focus on patients’ experience with MTX.Objectives:Examine patient temporal experience of fatigue and nausea relating to oral MTX therapy for the treatment of RA and PsA.Methods:Adult US patients in the ArthritisPower registry with self-reported RA or PsA taking MTX for less than 10 years were invited to participate in the study via email invitation. Participants (pts) completed a screener and brief online survey. In an ancillary study to the ArthritisPower registry and using a self-controlled case series study design where pts serve as their own control to avoid between-person confounding, pts were asked to complete a set of up to 8 assessments within 6-36 hours (‘risk’) and 96-144 hours (‘control’) after taking their oral dose of MTX each week, for up to 4 weeks. Risk and control windows were selected based on the expected temporal relationship between MTX use and peak onset of these symptoms. Assessments included PROMIS short forms for same-day Fatigue, same-day Nausea/Vomiting, and Patient Global. Descriptive statistics were conducted using paired t-tests two-way comparisons. Within-person change in PROMIS scores between the risk (1-2 days after MTX) and control (4-6 days after MTX) windows were analyzed using mixed models for repeated measures, stratified on whether pts reported fatigue or nausea with MTX at baseline. Recruitment for this study is ongoing.Results:As of December 2019, 91 pts had participated, of whom 76.9% were living with RA and 28.6% with PsA, with mean baseline PROMIS Patient Global score (SD) of 39.5 (7.1). Mean age (SD) was 50.9 (12.0) years, 84.6% female, 92.3% White, with mean BMI 33.7 (8.8). Mean duration of MTX treatment among current users was 2.1 (2.8) years. Among pts, 41.8% were on a biologic DMARD and 58.2% on non-biologic DMARDs only. Among pts reporting baseline nausea (n=30, 33.0%) where paired within-week measures were observed (n=64 observations among 20 pts), the mean increase in the PROMIS Nausea score was 4.5 units (adjusted p=0.003). Among those reporting MTX-associated fatigue (n=39, 42.9%) as a side effect of MTX on their baseline survey where paired within-week measures were observed (n=96 observations among 28 pts), the mean increase in PROMIS Fatigue was 4.7 (adjusted p=0.004) units. In those pts, the proportion of pts with worsened nausea and fatigue with minimally important difference of >5 units7-8was 40.0% (nausea), and 60.7% (fatigue) [Figures 1 and 2].Conclusion:People taking MTX to manage RA or PsA commonly experience bothersome side effects, notably fatigue and nausea, that are temporally related to weekly MTX dosing. In this sample, one-third or more of pts were bothered by nausea or fatigue shortly after MTX dosing, many of them with clinically meaningful symptoms.References:[1]Singh JA, et al.Arthritis Rheumatol. 2016;68:1-26.[2]Singh JA, et al.Arthritis Rheumatol. 2019;71:5-32.[3]Mease P.Bull NYU Hosp Jt Dis. 2013;71.(suppl 1):S41.[4]Wang W, et al.Eur J Med Chem. 2018;158:502-516.[5]Wilsdon TD, et al.Cochrane Database Syst Rev. 2019;1:CD012722.[6]Husted JA, et al.Ann Rheum Dis. 2009;68:1553-1558.[7]Norman GR, et al.Med Care. 2003;41:582-92.[8]Bingham CO, et al.J Patient Rep Outcomes. 2019;3:14.Disclosure of Interests:W.

Abstract
OBJECTIVE Inappropriate granulocyte colony-stimulating factor use with myelosuppressive chemotherapy has been reported. Using the Oncology Services Comprehensive Electronic Records electronic medical record database, prophylactic granulocyte colony-stimulating factor (pegfilgrastim/filgrastim) use in cancer patients was assessed by febrile neutropenia risk level. METHODS Patients with nonmetastatic or metastatic breast, head/neck, colorectal, ovarian/gynecologic, lung cancer, or non-Hodgkin's lymphoma who received myelosuppressive chemotherapy from June 2013 to May 2014 were included. Prophylactic granulocyte colony-stimulating factor use with high-risk, intermediate-risk, and low-risk chemotherapy and distribution of National Comprehensive Cancer Network risk factors with intermediate-risk regimens were assessed. RESULTS Overall, 86,189 patients received ∼4.2 million chemotherapy cycles (high risk, 9%; intermediate risk, 48%; low risk, 43%). Prophylactic granulocyte colony-stimulating factor was given in 24% of cycles (high risk, 59%; intermediate risk, 29%; low risk, 11%). For nonmetastatic solid tumors, granulocyte colony-stimulating factor was given in 78% (high risk), 31% (intermediate risk), and 6% (low risk) of cycles. For metastatic solid tumors or non-Hodgkin's lymphoma, granulocyte colony-stimulating factor was given in 50% (high risk), 27% (intermediate risk), and 11% (low risk) of cycles. Among patients receiving intermediate-risk regimens with granulocyte colony-stimulating factor, febrile neutropenia risk factors were identified in 56% (95% confidence interval, 51.1-60.9%) of patients with nonmetastatic solid tumors (n = 400) and in 70% (64.5-73.5%) of patients with metastatic solid tumors or non-Hodgkin's lymphoma (n = 400). CONCLUSION Prophylactic granulocyte colony-stimulating factor use was appropriately highest for high-risk regimens and lowest for low-risk regimens yet still potentially underused in high risk regimens, overused in low-risk regimens, and not appropriately targeted in intermediate-risk regimens, indicating a need for further education on febrile neutropenia risk evaluation and appropriate granulocyte colony-stimulating factor use.

Abstract
BACKGROUND Population-based cohorts of immune thrombocytopenia (ITP) are useful for understanding occurrence, clinical characteristics and long-term clinical course. This paper describes the content of the Nordic Country Patient Registry for Romiplostim (NCPRR) and provides prevalence and incidence estimates of chronic ITP (cITP). METHODS The NCPRR, a cohort study established in 2009, includes all adult (≥ 18 years) patients in Denmark, Sweden and Norway with cITP (defined as ITP lasting > 12 months and platelet count < 100 × 109/L), combining data from national health registries and medical records. The NCPRR currently includes prevalent cITP patients diagnosed before 2009 and incident cITP patients diagnosed during 2009-2016. The registry obtains clinical information for cITP patients, including comorbidities, treatments, laboratory values, and complete follow-up for various outcomes. FINDINGS The NCPRR currently includes 3831 patients with cITP (1258 prevalent; 2573 incident). In 2009, the prevalence of registered cITP was 10 · 0/100,000 (95%CI:9 · 1-11 · 0) adult persons in Denmark and 10 · 7/100,000 (95% CI: 9 · 9-11 · 4) adults in Sweden. During 2009-2016, the incidence rates of cITP per 100,000 person-years were 2 · 8 (95%CI: 2 · 6-3 · 0), 1 · 8 (95%CI: 1 · 7-1 · 9) and 2 · 1 (95%CI: 1 · 9-2 · 2) in Denmark, Sweden and Norway, respectively. Fifty-eight percent of cITP patients were women. At NCPRR inclusion, 30.2% were aged ≥ 70 years, 23% had a platelet count < 50 × 109/L, 17.4% were splenectomized, 41% had prior ITP therapy, and 8.6% had severe comorbidity. INTERPRETATION The NCPRR provides population-based data on the epidemiology and characteristics of almost 4000 cITP patients and is a valuable resource for research. FUNDING This study was partly funded by a research grant from Amgen to Aarhus University.

Abstract
INTRODUCTION Giant-cell tumor of bone (GCTB) is a locally aggressive histologically benign neoplasm with a less common malignant counterpart. Longitudinal data sources on GCTB are sparse, limited to single institution case series or surgical outcomes studies. The Swedish Cancer Registry is one of the few national population-based databases recording GCTB, representing a unique source to study GCTB epidemiology. We estimated incidence rate (IR) and overall mortality rates based on registry data. MATERIALS AND METHODS We identified patients with a GCTB diagnosis in the Swedish Cancer Registry from 1983 to 2011: benign (ICD-7 196.0-196.9; PAD 741) and malignant (PAD 746). Results were stratified by age at diagnosis, gender, and anatomical lesion location. RESULTS The cohort included 337 GCTB cases (IR of 1.3 per million persons per year). The majority (n=310) had primary benign GCTB (IR of 1.2 per million per year). Median age at diagnosis was 34 years (range 10-88) with 54% (n=183) females. Malignant to benign ratio for women was 0.095 (16/167) and for men 0.077 (11/143). Incidence was highest in the 20-39 years age group (IR of 2.1 per million per year). The most common lesion sites were distal femur and proximal tibia. Mortality at 20 years from diagnosis was 14% (n=48) and was slightly higher for axial (17%; n=6) and pelvic (17%; n=4) lesions. Recurrence occurred in 39% of primary benign cases and 75% of primary malignant cases. CONCLUSIONS In our modern population-based series primary malignant cases were uncommon (8%), peak incidence 20-39 years with slight predominance in women. Recurrence rates remain significant with overall 39% occurring in benign GCTB, and 75% in malignant form. The linkage between databases allowed the first population based estimates of the proportion of patients who received surgery at initial GCTB diagnosis, and those who also received subsequent surgeries.

Abstract
INTRODUCTION Canadian guidelines define castration-resistant prostate cancer (CRPC) at high risk of developing metastases using PSA doubling time (PSADT) < 8 months, whereby men may be offered more frequent bone scans/imaging. We evaluated PSA data from nonmetastatic (M0) prostate cancer patients treated at urology and oncology clinics across the United States (US) to describe the proportion and characteristics of patients who met CRPC and high-risk criteria. MATERIALS AND METHODS We identified M0 prostate cancer patients aged = 18 years receiving androgen deprivation therapy (ADT) in 2011 from electronic health records (EHR), covering 129 urology and 64 oncology practices across the US. We estimated the proportion of prostate cancer patients with evidence of CRPC (consecutive rising PSAs) and subsets that may be at high risk (using several PSA and PSADT cut-points). RESULTS Among 3121 M0 prostate cancer patients actively treated with ADT, 1188 (38%) had evidence of CRPC. Of these, 712 (60%) qualified as high risk in 2011 based on PSADT < 8 months (equivalent to = 8 months in these data). Men = 65 years were more likely to have evidence of CRPC than younger men, although younger men were more likely to have evidence of high-risk disease. CRPC was more common among men receiving ADT in the oncology setting than the urology setting (48% versus 37%). CONCLUSIONS In this large EHR study with patient-level PSA data, 38% of men with M0 prostate cancer treated with ADT had CRPC. Approximately 60% of M0 CRPC patients may experience a PSADT of < 8 months. These findings require validation in a Canadian patient population.

Abstract
BACKGROUND Estimating the incidence of giant cell tumor of bone is challenging because few population-based cancer registries record benign bone tumors. We compared two approaches, the indirect (relative index) estimation approach used in The Burden of Musculoskeletal Diseases in the United States (BMUS) and a direct incidence rate approach (from registries that record giant cell tumor), to estimate giant cell tumor incidence in France, Germany, Italy, Spain, the U.K., Sweden, Australia, Canada, Japan, and the U.S. METHODS Giant cell tumor of bone incidence was calculated with use of the BMUS relative index of giant cell tumor to osteosarcoma in three scenarios (low, base case, and high) from case series. We compared the BMUS approach with the latest data from tumor registries in Australia (1972 to 1996), Japan (2006 to 2008), and Sweden (1993 to 2011) that record giant cell tumors. United Nations population estimates were used to project results to 2013. RESULTS The low scenario in the BMUS approach reflects data from Unni and Inwards; the incidence of giant cell tumor of bone is 0.34 relative to osteosarcoma. As the incidence of osteosarcoma is 31.4% of the total incidence of bone and joint cancers, the incidence of giant cell tumor is 0.11 times that of all bone and joint cancers. The base scenario reflects the series by Mirra et al., with a giant cell tumor incidence of 0.47 relative to osteosarcoma (0.15 to all bone and joint cancers). The high scenario reflects the series by Ward, with an incidence of 0.84 relative to osteosarcoma (0.26 to all bone and joint cancers). Differences among the three series reflect referral to a national center of excellence compared with referral to a local oncology practice. Registry data indicated a giant cell tumor incidence rate per million per year of 1.33 in Australia, 1.03 in Japan, and 1.11 in Sweden in 2013. The estimated incidence rate per million in the ten countries in 2013 ranged from 1.03 (Japan) to 1.17 (Canada) with use of the registry-based approach and from 0.73 (Japan) for the low scenario) to 2.20 (Germany) for the base case with use of the BMUS approach. CONCLUSIONS Giant cell tumor of bone affects approximately one person per million per year in the ten countries studied. Estimates derived with use of age-specific incidences from tumor registries were typically within the range of the low and base case BMUS scenarios. We recommend the registry-derived method for estimating the incidence of giant cell tumor.

Abstract
111 Background: Increasing emphasis on assessing the quality of treatment (tx) for cancer patients highlights the need for real-world data sets that can address critical policy questions about cancer care in the US. This study examined treatment and mortality in women with incident early-stage breast cancer (BC) 2007-2009 using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data. Methods: We identified women age ≥66 years at the diagnosis of AJCC stage II/III BC between 2007-2009, who received surgery and were enrolled with Medicare Parts A and B. Women were followed from definitive surgery until the end of 2010, death, or change in enrollment status. Risk (cumulative incidence proportion [CIP]) of all-cause death was calculated with 95% confidence intervals (CI) using the Kaplan-Meier method stratified by tumor characteristics and tx type. Results: The cohort included 10,048 women with stage II (78%) or III (22%); 58% were ≥75 years and 78% had hormone-receptor (HR) positive tumors (77% ER positive, 64% PR positive). After the definitive surgery, 1,271 deaths reflected a CIP of 5.7% (95% CI 5.3-6.2) at 1 year, 10.9% (10.2-11.5) at 2 years, and 16.9% (15.9-17.9) at 3 years. Unadjusted mortality (Table) was higher among those without chemotherapy (chemo), women with neo-adjuvant tx, and those identified as “triple negative” phenotype (HR negative, no trastuzumab). Conclusions: Linking SEER and Medicare allowed us to assess mortality according to tumor characteristics and cancer treatments, respectively, which are both related to prognosis. The use of administrative data from Medicare should be further enhanced with inclusion of test results from standard gene expression panels to ensure a better match of therapy for the patient and adequate assessment of resource utilization.

Abstract
163 Background: Androgen deprivation therapy (ADT) is the cornerstone treatment of metastatic prostate cancer (PC), but is frequently used in the non-metastatic (M0) setting. After a variable period of hormone sensitivity, most patients develop castration-resistant prostate cancer (CRPC). These men are at increased risk of developing bone metastases (BM), particularly in those with higher serum PSA and shorter PSA doubling time (DT). The epidemiology and natural history of M0 CRPC has not been well studied in a population-based setting. Methods: Using HFHS patient records, a retrospective cohort study was conducted among 723 men diagnosed with M0 PC between 1996 and 2005 (with follow-up [f/u] for outcomes through 12/31/2008), who received ADT, including 613 men with serial PSA measurements for CRPC determination. CRPC was defined as 2 consecutive PSA rises, with “high-risk” defined as PSA ≥ 8 ng/mL or PSA DT ≤ 10 months (mos) after the development of CRPC. The risk of subsequent BM was estimated for the overall cohort and for the CRPC and non-CRPC subsets. Results: The median age among patients in the study was 73 years, 48% were African American, and median f/u time after ADT initiation was 58 mos. 15% (n=93) met criteria for CRPC during f/u (with a median of 23 mos between ADT initiation and establishment of CRPC), with the majority considered being at high risk (n=81). Among the entire cohort, 74 men (10%) developed BM during f/u. The rate of BM was 4 times higher among CRPC patients compared to non-CRPC patients (p<0.001), with a median of 6 mos between CRPC and subsequent BM. No racial difference was observed with either the incidence of CRPC or BM. Conclusions: The HFHS resource allowed for investigation of disease progression in a racially diverse population. A substantial proportion of M0 PC patients on ADT will eventually develop CRPC and once castration-resistant, risk of BM is high.

Abstract
4659 Background: ADT is the cornerstone treatment of metastatic PC, but the nature and extent of its use in the M0 setting is less well-described. We sought to estimate the current prevalence of M0 PC patients actively receiving continuous ADT (≥6 months) in the US. Methods: Two point-prevalent cohorts on 12/31/2008 with continuous insurance coverage in 2008 were assembled: men aged 45-64 years (yrs) enrolled in commercial health plans (MarketScan) and men aged ≥67 yrs enrolled in fee-for-service (FFS) Medicare (Medicare 5% sample). Among those with evidence of PC and no evidence of metastases, we selected men who had continuous exposure to gonadotropin-releasing hormone agonists during at least the last 6 months of 2008 or received bilateral orchiectomy prior to 7/1/2008. The number of prevalent ADT users was extrapolated to the entire national commercially insured population aged 45-64 yrs and to the entire Medicare FFS population aged ≥65 yrs using person-level weights. Applying age-specific prevalence estimates to the US Census population on 12/31/2008, we estimated the number of prevalent ADT users in the total US male population aged ≥45 yrs. Results: An estimated 11,935 (95% confidence interval [CI]: 11,310-12,561) commercially insured men aged 45-64 yrs and 115,468 (95% CI: 112,304-118,633) Medicare FFS men aged ≥65 yrs were M0 PC patients actively receiving continuous ADT for ≥6 months on 12/31/2008. Extrapolated to the total US male population aged ≥45 yrs, this estimate was 188,916 (95% CI: 184,104-193,727). Age-specific prevalence (N [95% CI]) on 12/31/2008 is presented in the table. Conclusions: We projected nearly 190,000 US men with M0 PC were actively receiving continuous ADT for ≥6 months at the end of 2008, and the vast majority (91%) of these men were aged ≥65 yrs. Additional work will address timing of initiation, duration, and other aspects of ADT use in this large population of M0 PC patients. [Table: see text]

Abstract
1581 Background: Prostate-specific antigen (PSA) is a well-known PC biomarker. In the M0 setting, rising PSAs despite ADT is an indication of the development of castration-resistant prostate cancer (CRPC). In this disease state, men are at risk for developing bone metastasis (BM), which is associated with significant morbidity and may negatively affect survival. Using real-world data, we explored PSA-based criteria to identify patients who develop CRPC while on ADT and the subsets that may be at increased risk of BM. Methods: We used the Oncology Services Comprehensive Electronic Records (OSCER) database, which includes electronic medical record (EMR) data on cancer patients from 328 urology and oncology clinics in the US. Eligible patients were adult men with M0 PC with ≥1 PSA recorded between 3/1/2010 and 2/28/2011 and currently receiving ADT (gonadotropin-releasing hormone agonists or bilateral orchiectomy) for ≥6 months (mos). We defined CRPC as two sequential PSA rises while on ADT and high risk for BM as any PSA ≥8 ng/mL or PSA doubling time (DT) ≤10 mos, as described by Smith MR et al, Lancet 2012. We explored subsets of CRPC patients who may be at even higher risk of BM using PSA thresholds (≥8 ng/mL and ≥20 ng/mL) and DT (≤4, 6, 8, and 10 mos). Results: Of 1,818 men with M0 PC receiving ADT ≥6 mos, 36% (N=646) met the CRPC definition, of whom 80% (N=517) had PSA ≥8 ng/mL and/or PSA DT ≤10 mos (high risk). PSA DT alone explained 63% (44% / 70%) to 93% (65% / 70%) of subgroup eligibility (Table), and emerged as a main driver in defining increased risk of BM for CRPC subsets. Conclusions: In this analysis of EMR data, over one-third of men with M0 PC on ADT met criteria for CRPC, and most CRPC patients (80%) may be considered at high risk for BM. Requiring ≥3 PSAs to define CRPC may be a limitation; however, because PSAs are closely monitored in patients on ADT, these definitions of CRPC and high risk may be useful in practice. These data suggest that PSA DT may be a more clinically meaningful measure of defining CRPC subsets than absolute PSA thresholds. [Table: see text] .

Abstract
e15147 Background: Androgen deprivation therapy (ADT) is the cornerstone treatment of advanced PC, but is frequently used in the M0 setting. After a variable period of hormone-sensitivity, most patients develop CR disease (rising prostate-specific antigen [PSA] despite ongoing ADT). These men are at increased risk of developing bone metastases (BMT), particularly in those with higher serum PSA and shorter PSA doubling time (DT). The epidemiology and natural history of M0 CRPC has not been well-studied in a population-based setting. Methods: A retrospective cohort study was conducted using HFHS administrative data and included 691 men diagnosed with M0 PC between 1996 and 2005, who received ADT, with serial PSA measurements to determine CR. Patient records through 12/31/2008 were reviewed for outcomes of interest. CRPC was defined as 2 consecutive PSA rises, with “high risk” defined as PSA ≥8 ng/mL or PSA DT ≤10 months (mos) after the development of CRPC (Smith MR et al. Lancet 379:39-46, 2012). The risk of BMT was estimated for the entire cohort and for the CRPC and high-risk CRPC subsets. Results: Of the 691 patients included in the cohort (median age: 73 years, 48% African American), 98% received only GnRH agonists and 2% had orchiectomy. Median follow-up for the entire cohort after ADT initiation was 49 mos (IQR=45). 101 patients (15%) met criteria for CRPC during follow-up, with a median of 18 mos on active ADT prior to CRPC development (IQR=14). Of CRPC patients, 85% met criteria for high-risk (of those, 16% had PSA ≥8 ng/mL, 12% had PSA DT ≤10 mos, and 72% had both). Among all patients, 12% (n=82) developed BMT during follow-up, with 42% (n=36) of the high-risk CRPC subset developing BMT. Median time from high-risk CRPC to BMT was 9 mos (IQR=17). Conclusions: The HFHS resource allowed for our investigation of PSA characteristics corresponding to disease progression in a racially diverse patient population. A substantial proportion of M0 PC patients on ADT will eventually develop CR disease. Once a patient has CRPC, the risk of BMT is relatively high.

Abstract
e15169 Background: ADT is well-established for metastatic PC but is also used in men with less advanced PC. Patterns of ADT use in the M0 PC setting have not been well-described. Methods: Medicare claims in 2005 for men aged ≥66 years (yrs) were assessed for use of gonadotropin-releasing hormone agonists or bilateral orchiectomy. The cohort was limited to men who, during the 15 months (mos) prior to their first 2005 ADT claim, had continuous Parts A + B coverage, a diagnosis code for PC, no claims for metastases (except lymph nodes), and no claims for ADT. Follow-up (f/u) was from ADT initiation to 3 yrs, death, or change in Medicare coverage. Regimen duration was defined by combining claim service count and dosage with FDA label dosing. Because ADT has biologic activity beyond the recommended regimen duration, active dose time was calculated by adding 3 and 6 mos to claims for regimens <6 mos and ≥6 mos, respectively. Interruption was defined as ≥180 days from end of active dose time to next ADT claim. Results: We identified 3246 M0 PC patients aged ≥66 yrs who initiated ADT in 2005 but describe results in the 2161 who had 3 full yrs of f/u (data for the entire cohort were similar). Nearly 70% received only 1 type of ADT agent during f/u (25% had 2 types, 5% had 3 or 4 types), and 73% started on a 3-or 4-month regimen. The distribution of patients by first ADT type (and by type received at any point) was: leuprolide injection: 54% (67%); goserelin implant: 36% (43%); triptorelin injection: 6% (19%); leuprolide implant: 2% (4%); orchiectomy: <1% (1%); and histrelin implant: 0% (3%). Use of >1 type of ADT agent was more common in men who began with goserelin (45%) or triptorelin (53%) versus leuprolide (≤24%). At three years after ADT initiation, 36% received ADT for the entire 36-month period, 15% for 24-35 mos, 17% for 12-23 mos, and 32% for <12 mos. Interruption in active therapy occurred in only 13%. Conclusions: Most elderly men with M0 PC initiating ADT in 2005 started on a 3- or 4-month leuprolide or goserelin regimen. Though these agents remained the most commonly used throughout f/u, switching was common (30% used >1 type during f/u). ADT was continued for at least 2 yrs in nearly half and extended to 3 yrs in over one-third of the cohort.

Abstract
BACKGROUND The prevalence of metastatic bone disease in the US population is not well understood. We sought to estimate the current number of US adults with metastatic bone disease using two large administrative data sets. METHODS Prevalence was estimated from a commercially insured cohort (ages 18-64 years, MarketScan database) and from a fee-for-service Medicare cohort (ages ≥65 years, Medicare 5% database) with coverage on December 31, 2008, representing approximately two-thirds of the US population in each age group. We searched for claims-based evidence of metastatic bone disease from January 1, 2004, using a combination of relevant diagnosis and treatment codes. The number of cases in the US adult population was extrapolated from age- and sex-specific prevalence estimated in these cohorts. Results are presented for all cancers combined and separately for primary breast, prostate, and lung cancer. RESULTS In the commercially insured cohort (mean age = 42.3 years [SD = 13.1]), we identified 9505 patients (0.052%) with metastatic bone disease. Breast cancer was the most common primary tumor type (n = 4041). In the Medicare cohort (mean age = 75.6 years [SD = 7.8]), we identified 6427 (0.495%) patients with metastatic bone disease. Breast (n = 1798) and prostate (n = 1862) cancers were the most common primary tumor types. We estimate that 279,679 (95% confidence interval: 274,579-284,780) US adults alive on December 31, 2008, had evidence of metastatic bone disease in the previous 5 years. Breast, prostate, and lung cancers accounted for 68% of these cases. CONCLUSION Our findings suggest that approximately 280,000 US adults were living with metastatic bone disease on December 31, 2008. This likely underestimates the true frequency; not all cases of metastatic bone disease are diagnosed, and some diagnosed cases might lack documentation in claims data.

Abstract
Renal impairment (RI) and events potentially leading to RI were reported in idiopathic thrombocytopenic purpura (ITP) patients with specific medications. This study was conducted to estimate the incidence rate (IR) of RI, hemoglobinuria and hemoglobinemia (HE) and characterize baseline risk factors in ITP and ITP-free patients. Incident ITP and matched non-ITP patients were identified from an electronic medical record database from 1990 to 2002. ITP patients were classified by the treatment first received (initiators) or ever received (users). All cohorts were followed for study outcomes. IRs were calculated and standardized by age and gender. A total of 881 ITP and 4,496 ITP-free patients yielded 3,044 and 16,006 person-years, respectively. The ITP cohort had a slightly higher prevalence of autoimmune diseases and infections than the ITP-free cohort. The IR (/10,000 person-years) for RI, hemoglobinuria and HE was 14.2, 35.7, and 7.1 in the ITP cohort; 10.0, 48.8, and 0 in the ITP-free cohort; and 18.3, 37.1, and 6.1 in untreated ITP patients, respectively. The risk of RI, HE or hemoglobinuria was not found to differ substantially between ITP and non-ITP patients or across ITP treatments.

Abstract
BACKGROUND Concerns have been raised about a potential link between the use of TNF inhibitors and development of malignancy in the pediatric population. We examined the worldwide experience of etanercept use in pediatric patients and the occurrence of malignancies as reported from clinical trials, registry studies, post-marketing surveillance, and published scientific literature. METHODS All reports of "malignancy" in pediatric patients (including subjects who received etanercept before age 18 and developed a malignancy before age 22) were collected from the etanercept clinical trials database and global safety database using the Medical Dictionary for Regulatory Activities (MedDRA; v12.0) standardized MedDRA query "Malignancies" from 1998 to August 2009. Cases were collected irrespective of treatment indication. All cases were included regardless of exposure to other TNF blockers or other biologics and whether the other exposure was before or after etanercept. RESULTS A total of 18 potential malignancies were identified: 4 leukemias, 7 lymphomas, and 7 solid tumors. Three of the 18 malignancies remain unconfirmed. No malignancies were reported from clinical trials or the open-label extension studies in any indication in children. CONCLUSION The data suggest that there does not appear to be an increased risk of malignancy overall with the use of etanercept. Among etanercept-exposed patients aged 4 to 17 years, the estimated worldwide and US reporting rates for lymphoma were approximately 0.01 per 100 patient-years (1 in 10,000 pt-yrs). While the reported rate of lymphoma is higher in pediatric patients treated with etanercept than in normal children, the expected rate of lymphoma in biologic naïve JIA patients is currently unknown. The risk of TNF inhibitors in the development of malignancies in children and adolescents is difficult to assess because of the rarity of malignant events, the absence of knowledge of underlying frequency of leukemia and lymphoma in JIA, and the confounding use of concomitant immunosuppressive medications.

Abstract
BACKGROUND The incidence of pure red cell aplasia (PRCA) in chronic kidney disease patients treated with epoetins increased substantially in 1998, was shown to be antibody mediated, and was associated predominantly with subcutaneous administration of Eprex. A technical investigation identified organic compounds leached from uncoated rubber stoppers in prefilled syringes containing polysorbate 80 as the most probable cause of the increased immunogenicity. METHODS This study investigated whether the incidence of PRCA was higher for exposure to the product form containing leachates than for leachate-free product forms. Antibody-mediated PRCA cases were classified according to indication, product form, and route of administration. Exposure estimates were obtained by country, indication, route of administration, and product form. RESULTS For 2001 to 2003, the PRCA incidence rate for patients with subcutaneous exposure to Eprex in prefilled syringes with polysorbate 80 and uncoated rubber stoppers (leachates present) was 4.61/10,000 patient years (95% CI 3.88-5.43) versus 0.26/10,000 patient years (95% CI 0.007-1.44) for syringes with coated stoppers (leachates absent). The rate difference was 4.35/10,000 patient years (95% CI 3.44-5.26; P < 0.0001); the rate ratio was 17 (95% CI 3.14-707). A substantial rate difference remained in sensitivity analyses that adjusted for exposure to multiple product forms. CONCLUSION The epidemiologic data, together with the chemical and immunologic data, support the hypothesis that leachates from uncoated rubber syringe stoppers caused the increased incidence of PRCA associated with Eprex. Currently, all Eprex prefilled syringes contain fluoro-resin coated stoppers, which has contributed to decreased incidence of PRCA with continued surveillance.

Abstract
BACKGROUND Fluoroquinolones (FQs) have been infrequently used in children, largely because of concern that these agents can cause lesions of the cartilage in juvenile animals. However, the relevance of this laboratory observation to children treated with FQs is unknown. A retrospective, observational study was conducted to assess the incidence and relative risk of tendon or joint disorders (TJDs) that occur after use of selected FQs compared with azithromycin (AZ), a drug with no known effect on cartilage or tendons in humans or animals. METHODS An automated database was searched to identify patients younger than 19 years who had been prescribed ofloxacin (OFX), levofloxacin, ciprofloxacin (CPX), or AZ. Potential cases of TJD occurring within 60 days of a prescription of one of the study drugs were identified based on assignment of a claims diagnosis consistent with a TJD within this period. Verified cases were identified by a blinded review of abstracts of medical records from subjects identified as potential cases. RESULTS The incidence of verified TJD was 0.82% for OFX (13 of 1593) and CPX (37 of 4531) and was 0.78% for AZ (118 of 15,073). The relative risk of TJD for OFX and CPX compared with AZ was 1.04 (95% confidence interval, 0.55 to 1.84) and 1.04 (95% confidence interval, 0.72 to 1.51), respectively. The distributions of claims diagnoses and time to onset of TJD were comparable for all groups. The most frequently reported category of TJD involved the joint followed by tendon, cartilage and gait disorder. CONCLUSIONS In this observational study involving more than 6000 FQ-treated children, the incidence of TJD associated with selected FQ use in children was <1% and was comparable with that of the reference group, children treated with AZ.

Abstract
An unusual case of deciduoid mesothelioma occurring in the anterior abdominal wall of a 30-year-old woman is reported. The patient had a palpable mass that was resected. The mass appeared largely cystic with solid areas. Histologically, the tumor cells appeared epitheloid with eosinophilic cytoplasm and prominent nucleoli. The tumor was positive for keratins and vimentin and negative for CEA and Ber-EP4. Electron microscopy showed features of mesothelial cells characterized by well-formed desmosomes and long, slender microvilli. In contrast to previously reported cases of deciduoid mesothelioma, this tumor developed in the abdominal wall and appears to have a benign course.

Abstract
Cystic fibrosis (CF) is a complex illness characterized by chronic lung infection leading to deterioration in function and respiratory failure in over 85% of patients. An understanding of the risk factors for that progression and the interaction of these factors with current therapeutic strategies should materially improve the prevention of this progressive lung disease. The Epidemiologic Study of Cystic Fibrosis (ESCF) was therefore designed as a multicenter, longitudinal, observational study to prospectively collect detailed clinical, therapeutic, microbiologic, and lung function data from a large number of CF treatment sites in the U.S. and Canada. The ESCF also serves an important role as a phase-IV study of dornase alfa. To be eligible for enrollment, subjects must have the diagnosis of CF and receive the majority of their care at an ESCF site. In this paper, the authors present the ESCF study design in detail. Further, enrollment data collected at 194 study sites in 18,411 subjects enrolled from December 1, 1993 to December 31, 1995 are presented in summary form. This comprehensive study is unique in the detail of clinical data collected regarding patient monitoring and therapeutic practices in CF care. Two companion articles present data regarding practice patterns in cystic fibrosis care, including data on resource utilization and prescribing practices.

Abstract
An observational study was conducted at 18 transplant centers in the United States and Canada to characterize the platelet recovery of patients receiving myeloablative therapy and stem cell transplantation and to determine the clinical variables influencing recovery, determine platelet utilization and cost, and incidence of hemorrhagic events. The study included 789 evaluable patients transplanted in 1995. Clinical, laboratory, and outcome data were obtained from the medical records. Variables associated with accelerated recovery in multivariate models included (1) higher CD34 count; (2) higher platelet count at the start of myeloablative therapy; (3) graft from an HLA-identical sibling donor; and (4) prior stem cell transplant. Variables associated with delayed recovery were (1) prior radiation therapy; (2) posttransplant fever; (3) hepatic veno-occlusive disease; and (4) use of posttransplant growth factors. Disease type also influenced recovery. Recipients of peripheral blood stem cells (PBSC) had faster recovery and fewer platelet transfusion days than recipients of bone marrow (BM). The estimated average 60-day platelet transfusion cost per patient was $4,000 for autologous PBSC and $11,000 for allogeneic BM transplants. It was found that 11% of all patients had a significant hemorrhagic event during the first 60 days posttransplant, contributing to death in 2% of patients. In conclusion, clinical variables influencing platelet recovery should be considered in the design and interpretation of clinical strategies to accelerate recovery. Enhancing platelet recovery is not likely to have a significant impact on 60-day mortality but could significantly decrease health care costs and potentially improve patient quality of life.

Abstract
UNLABELLED This study was undertaken to determine the early experience of the embers of the COST Study Group with colorectal cancer treated by laparoscopic approaches. METHOD A retrospective review was performed of all patients with colorectal cancer treated with laparoscopy by the COST Study Group before August 1994. Tumor site, stage, differentiation, procedure completion, presence of recurrence (local, distant, trocar site), and cause of death were analyzed. RESULTS A total of 372 patients with adenocarcinoma of the colon and rectum were treated by laparoscopic approach between October 1991 and August 1994 (170 men and 192 women): right colectomy, 170; sigmoid colectomy, 55; low anterior resection, 56; abdominoperineal resection, 44; left colectomy, 22; colostomy, 8; total colectomy, 6; transverse colectomy, 7; exploration, 2. Conversion to an open procedure was required in 15.6 percent of cases. Operative mortality was 2 percent. Tumor characteristics were as follows: TNM state: I, 40 percent; II, 25 percent; III, 18 percent; IV, 17 percent; Differentiation: well-moderate, 88 percent; poor, 12 percent; carcinomatosis, 5 percent. Local (3.6 percent) and distant implantation occurred in four patients (1.1 percent). Only one of these patients died a cancer-related death (Stage III at 36 months). Cancer-related death rates increased with increasing stage of tumor: I, -4 percent; II, 17 percent; III, 31 percent; IV, 70 percent. CONCLUSION A laparoscopic approach to colorectal cancer results in early outcome after treatment that is comparable with conventional therapy for colorectal cancer. A randomized trial is needed to compare long-term outcomes of open and laparoscopic approaches with colorectal cancer.

Abstract
To evaluate the incidence and stage at which p53 alterations occur in human pancreatic carcinogenesis, we examined primary and metastatic carcinomas, carcinoma in situ, and hyperplastic lesions with and without atypia for p53 protein overexpression by immunohistochemical procedure. Overexpression of p53 was observed in 40% (10/25) of primary tumors, 29% (2/7) of metastatic tumors, 36% (5/14) of carcinoma in situ, and 35% (6/17) of hyperplastic lesions. These results suggest that p53 protein overexpression is not only a common genetic alteration but also occurs very early in the development of these tumors. It is suggested that p53 overexpression can be used as a marker to identify precursor lesions that have increased potential to develop into malignant tumors.

Abstract
Data from the 1969 and 1971 panels of the National Longitudinal Survey of Middle-Aged Men are analyzed to assess the mediating effects of locus of control beliefs in the relationship between stressful job and economic events and psycho-physiological well-being. The analyses indicate that men with internal locus of control orientations respond more adequately to stress than do those with external locus of control beliefs. A more detailed examination of the data revealed that men with moderately internal locus of control orientations cope more effectively with stress than those whose locus of control beliefs may be classified as extreme internal, extreme external or moderately external. The theoretical implications of these findings are discussed.

Abstract
The case of an 18-year-old man with coarctation of the aorta discovered on routine physical examination and subsequently surgically repaired is reported. Four months postoperatively, aneurysms developed at the repair site and thrombosis of both femoral arteries was noted. Following an attempt to repair the aneurysm and remove the thrombi, the patient became paraplegic; Aspergillus fumigatus was found infecting the aorta and femoral vessels. After additional operations and a course of amphotericin B to control the fungal infection, the patient died of intrathoracic bleeding originating from infected, aneurysmally dilated intercostal vessels in the area of the original coarctation repair. The complicating fungal infection of the operative site and the paraplegia are discussed. This report is among the first to present a patient with fungal endarteritis complicating operation for coarctation of the aorta.

Abstract
A cluster of five cases of non-O group 1 (non-O1) V. cholerae gastroenteritis occurred in one Florida locality during November 1979. Clinical findings included nausea, vomiting, and abdominal cramping in all affected persons; two had bloody diarrhea. All five persons gave a history of eating raw oysters within four days of onset of illness. A case-control study statistically associated the eating of raw oysters with development of illness (p = 0.0008); this finding was confirmed by a retrospective cohort study of patients hospitalized for diarrhea (p = 0.0001). Non-O1 V. cholerae organisms were isolated from oysters and water samples taken from areas where ill persons had obtained their oysters. In at least one instance the same serotype was isolated from a patient's stool specimen and from the water where the patient had obtained oysters. Non-O1 V. cholerae infection must be considered in the differential diagnosis of shellfish-associated gastroenteritis.

Abstract
Mesenteric tumefactions comprise a group of non-neoplastic conditions that present as an intra-abdominal mass. Symptoms vary from none to obstruction of the gastrointestinal tract. Histologic examination reveals dystrophy, fibrosis, or inflammation of the mesenteric fat. Despite a large number of descriptive terms currently in use, this study suggests that all these lesions are part of a single clinical and histologic continuum.
