RESUMO
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.

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.
RESUMO
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.

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.

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.
RESUMO
INTRODUCTION: The magnitude and frequency of temporally related methotrexate (MTX)-associated side effects in rheumatoid arthritis (RA) or psoriatic arthritis (PsA) patients are difficult to quantify using traditional research methods. As proof of concept designed in part to implement digital data collection for remote patient monitoring, we conducted a study implementing self-controlled case series analytic methods to understand MTX-related symptoms in RA or PsA. METHODS: In study phase 1, adults with RA or PsA from the ArthritisPower® Registry (past or current oral MTX users) participated in a cross-sectional survey. In phase 2, current MTX users participated in a longitudinal study and completed the Patient-Reported Outcomes Measurement Information System (PROMIS®) 1-day nausea/vomiting and fatigue measure. Within-person change in PROMIS scores between risk (6-36 h post-dose) and control (96-144 h post-dose) windows were compared using mixed models. RESULTS: The baseline survey was completed by 671 participants (mean age: 54 years, 88% female, 92% white, 79% with RA). Among current MTX users (353/671 [53%]), most reported MTX-associated side effects (216/353 [61%]), most frequently fatigue (161/353 [46%]). Among phase 2 participants with (n = 39) and without (n = 84) baseline nausea, mean increase in PROMIS nausea was 5.1 units (P < 0.0001) and 0.7 units (P = 0.135), respectively; among those with (n = 51) and without (n = 72) baseline fatigue, mean increase in PROMIS fatigue was 3.9 units (P = 0.0003) and 0.4 units (P = 0.554), respectively. CONCLUSIONS: Digital remote patient monitoring presents an opportunity to detect and address medication tolerability in real time. Using a novel study design to control for between-person confounding, the magnitude of nausea and fatigue experienced by participants with RA and PsA temporally related to weekly MTX use was substantial.
RESUMO
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.

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.

Biological disease-modifying antirheumatic drugs (bDMARDs) monotherapy may enhance adherence and decrease adverse events compared to combination therapy with conventional synthetic DMARDs (csDMARDs); however, persistence with bDMARD monotherapy has not been extensively studied. We explore persistence of etanercept monotherapy and monotherapy with other tumor necrosis factor inhibitors (TNFis) among patients first achieving remission/low disease activity (LDA) while on combination therapy with csDMARDs and a TNFi. Using Corrona registry data, the percentage of patients persistent with the index TNFi (etanercept versus other TNFis) over 6 and 12 months was determined. Factors influencing persistence and treatment patterns at 6 and 12 months were examined. Among 617 eligible patients, 56% of 182 patients on etanercept and 45% of 435 patients on other TNFis persisted with monotherapy at 6 months, 46% and 33%, respectively, at 12 months. Across first-line and subsequent biologic DMARDs, etanercept persistence was greater than other TNFi persistence by 10.8% (95% CI 2.1%, 19.6%) at 6 months and 11.4% (95% CI 0.9%, 21.9%) at 12 months. Patients on other TNFis were more likely to require reintroduction of csDMARD after 6 months (45% versus 35% for etanercept). Remission was the key predictor of persistence for both etanercept and other TNFi monotherapies. This retrospective, cohort study of registry data reflecting real-world practice indicates patients who achieve remission/LDA with combination csDMARD and TNFi therapy may successfully transition to TNFi monotherapy. Patients on etanercept monotherapy experienced greater persistence and less frequent reintroduction of a csDMARD than was observed for patients on other TNFi monotherapies.

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.

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.
RESUMO
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 (≥ 18â¯years) patients in Denmark, Sweden and Norway with cITP (defined as ITP lasting > 12â¯months and platelet count < 100â¯×â¯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 ≥â¯70â¯years, 23% had a platelet count < 50â¯×â¯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.
RESUMO
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 â¼4.2 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.

PURPOSE: Granulocyte colony-stimulating factors (G-CSF) are commonly used in clinical practice to prevent febrile neutropenia (FN). US and EU prescribing information and treatment guidelines from the NCCN, ASCO, and EORTC specify that pegfilgrastim, a long-acting (LA) G-CSF, should be administered at least 24 h after myelosuppressive chemotherapy. Nevertheless, many patients receive LA G-CSFs on the same day as chemotherapy. This systematic literature review evaluated the relative merits of same-day versus next-day dosing of LA G-CSFs. METHODS: A broad Ovid MEDLINE® and Embase® literature search was conducted that examined all publications indexed before May 9, 2016 that compared same-day versus next-day LA G-CSF administration. A congress abstract literature search included congresses from January 1, 2011 to April 6, 2016. The parameters for this review were prospectively delineated in a research protocol and adhered to the PRISMA Guidelines. RESULTS: The first part of the systematic literature search identified 1736 publications. After elimination of duplicates, title/abstract screening was conducted on 1440 records, and full text review was conducted on 449 publications. Eleven publications met all criteria and are included in this systematic review; of these, four included data from randomized or single arm prospective studies, and seven were retrospective studies. In most studies included in this review and across a variety of tumor types, administration of pegfilgrastim at least 24 h after myelosuppressive chemotherapy resulted in improved patient outcomes. CONCLUSIONS: Data from multiple publications support administration of pegfilgrastim at least 1 day after chemotherapy.

PURPOSE: Growth factors and antimicrobials can reduce complications of chemotherapy-induced myelosuppression. Their prophylactic use in elderly patients is important given the associated comorbidity in this age group. There is a developing trend by payers to include supportive care agents in chemotherapy care bundles, which could affect clinical practice. We examined whether the febrile neutropenia (FN) risk categories can be used to describe utilization in the Centers for Medicare & Medicaid fee-for-service system in older adults. METHODS: We conducted a retrospective cohort study using the Medicare 20% sample data to describe growth factor and antimicrobial use patterns in patients receiving chemotherapy for breast cancer, lung cancer, and non-Hodgkin lymphoma (NHL). RESULTS: The highest percentage of patients receiving granulocyte colony-stimulating factor (GCSF) within the first 5 days of a chemotherapy cycle were on high-FN-risk regimens, particularly for cycle 1 (73.7%, breast cancer; 61.5%, NHL) and cycle 2 (75.9%, breast cancer; 77.5%, NHL). Chemotherapy regimens for lung cancer are less myelotoxic, and growth factor use was more likely with latter cycles. Antibiotic use was lower at 15% within a cycle and appeared to be in response to complications. CONCLUSION: Practitioners use GCSF and antibiotics for elderly patients treated with potentially toxic chemotherapy, while comorbidity burden plays a role for patients treated with less myelotoxic regimens. The complexity of these choices in clinical practice should be considered in the proposed reimbursement changes being piloted by Medicare and private insurance companies seeking treatment cost reductions, as altered use could affect safety and efficacy.

This meta-analysis describes the incidence rate of arterial and venous thromboembolism (ATE and VTE) in patients with immune thrombocytopenia (ITP), and the relative risk of ATE and VTE in patients with ITP and comparable populations without ITP. MEDLINE and EMBASE were systematically searched for observational studies reporting incidence rates of ATE and VTE in populations with and without ITP between 1996 and 2013 [follow-up completed before thrombopoietin receptor (TPOr) agonists were commercially available]. Three large, population-based studies were identified from Denmark, the United Kingdom, and the United States. The incidence of ATE per 100 patient-years among patients with ITP ranged from 1.0 to 2.8, and among populations without ITP ranged from 0.7 to 1.8; the summary relative risk adjusted for matching factors (aRR) was 1.5 [95 % confidence interval (CI) 1.3, 1.8]. The incidence of VTE per 100 patient-years among patients with ITP ranged from 0.4 to 0.7, and among populations without ITP ranged from 0.1 to 0.4; the summary aRR (95 % CI) was 1.9 (1.4, 2.7). The risk of ATE and VTE among patients with ITP, based on evidence from three large, population-based observational studies, should be considered when evaluating the risk of thromboembolism attributed to ITP treatments, such as TPOr agonists.

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.

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.

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.
