RESUMO
Purpose: Topical treatments for mild-to-moderate (MM) atopic dermatitis (AD) include emollients, corticosteroids, calcineurin inhibitors, a Janus kinase inhibitor, and a phosphodiesterase 4 inhibitor, which differ in multiple ways. This study aimed to quantify the conditional relative importance (CRI) of attributes of topical treatments for MM AD among adult and adolescent patients and caregivers of children with MM AD.Materials and methods: A discrete-choice experiment (DCE) survey was administered to US adults and adolescents with MM AD and caregivers of children with MM AD. Each choice task comprised 2 hypothetical topical treatments characterized by efficacy, adverse events, vehicle, and application frequency. Data were analyzed using a random-parameters logit model to calculate the CRI of each attribute.Results and conclusions: 300 adults, 331 adolescents, and 330 caregivers completed the DCE. Avoiding changes in skin color (CRI 29.0) and time until itch improves (26.6) were most important to adults, followed by time until clear/almost clear skin (17.8). Application frequency (3.0) did not have a statistically significant impact on adults' choices. Adolescents were less concerned about changes in skin color than adults or caregivers; caregivers were less concerned about time until clear/almost clear skin than patients. Physicians should consider age-relevant aspects of preferences in treatment discussions with patients and caregivers.

INTRODUCTION: Invasive Escherichia coli disease (IED) can lead to sepsis and death and is associated with a substantial burden. Yet, there is scarce information on the burden of IED in Asian patients. METHODS: This retrospective study used US hospital data from the PINC AI™ Healthcare database (October 2015-March 2020) to identify IED cases among patients aged ≥ 60 years. IED was defined as a positive E. coli culture in blood or other normally sterile body site (group 1 IED) or positive culture of E. coli in urine with signs of sepsis (group 2 IED). Eligible patients with IED were classified into Asian and non-Asian cohorts based on their reported race. Entropy balancing was used to create cohorts with similar characteristics. Outcomes following IED were descriptively reported in the balanced cohorts. RESULTS: A total of 646 Asian and 19,127 non-Asian patients with IED were included (median age 79 years; 68% female after balancing). For both cohorts, most IED encounters had community-onset (> 95%) and required hospitalization (Asian 96%, mean duration 6.9 days; non-Asian 95%, mean duration 6.8 days), with frequent admission to intensive care (Asian 35%, mean duration 3.3 days; non-Asian 34%, mean duration 3.5 days), all standardized differences [SD] < 0.20. Compared to non-Asian patients, Asian patients were more likely to be discharged home (54% vs. 43%; SD = 0.22), and less likely to be discharged to a skilled nursing facility (24% vs. 31%; SD = 0.16). In-hospital fatality rates during the IED encounter were similar across cohorts (Asian 9%, non-Asian 10%; SD = 0.01). Most E. coli isolates showed resistance to ≥ 1 antibiotic (Asian 61%; non-Asian 64%) and 36% to ≥ 3 antibiotic classes (all SD < 0.20). CONCLUSION: IED is associated with a substantial burden, including need for intensive care and considerable mortality, in Asian patients in the USA that is consistent with that observed for non-Asian patients.
RESUMO
BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease that is associated with allergic comorbidities. However, studies examining comorbidities in childhood AD are incomplete, which may contribute to suboptimal care. OBJECTIVE: The objective was to compare the risk of developing different allergic and non-allergic comorbidities among children with AD to that of a matched non-AD reference cohort in Sweden. METHODS: This was a nationwide population-based cohort study using longitudinal data from primary and specialist care registers. Patients with AD were identified by confirmed diagnosis in primary or specialist care. The non-AD reference cohort was randomly drawn from the general population and matched 1:1 with the AD patients. The risk of developing the following conditions was evaluated: hypersensitivity and allergic disorders, neurological disorders, psychiatric disorders, infections, immunological and inflammatory disorders, Type 1 diabetes (T1D), endocrine and metabolic disorders, skeletal disorders, ocular disorders and malignancies. RESULTS: This study included 165,145 patients with AD (mild-to-moderate [n = 126,681] and severe [n = 38,464]) and an equally sized reference cohort. Patients with AD displayed a higher risk of developing comorbid conditions for all investigated categories, except for T1D and skeletal disorders, compared with the reference cohort. The highest risk compared with the reference cohort was observed for hypersensitivity and allergic disorders (hazard ratio [HR]: 3.87), followed by malignancies (HR: 2.53) and immunological and inflammatory disorders (HR: 2.36). Patients with AD also had higher risk of developing multiple comorbidities (≥2). The risk of comorbidity onset increased alongside AD severity and patients with active AD were associated with increased risk of comorbidity onset compared with patients in remission. CONCLUSIONS: The clinical burden of AD is substantial for children with AD and patients are at an increased risk of developing several comorbid conditions extending beyond the atopic march. Our results also showed a positive association between worsening severity of AD and an increased risk of comorbidity onset.

INTRODUCTION: Atopic dermatitis (AD) is a chronic and relapsing inflammatory skin disease that negatively impacts overall health, quality of life (QoL), and work productivity. Prior studies on AD burden by severity have focused on moderate-to-severe disease. Here, we describe the clinical and humanistic burden of AD in Europe across all severity levels, including milder disease. METHODS: Data were analyzed from the 2017 National Health and Wellness Survey from adult respondents with AD in the EU-5 (France, Germany, Italy, Spain, and the UK). AD disease severity was defined based on self-reported assessments as "mild," "moderate," or "severe" and by Dermatology Life Quality Index (DLQI) severity bands. Self-reported outcomes for AD respondents by severity were assessed using propensity score matching. These outcomes included a wide range of selected medical/psychological comorbidities, overall QoL and functional status (EuroQol 5-Dimensions 5-Level and Short Form-36 version 2 questionnaires), and work productivity and activity impairment (Work Productivity and Activity Impairment questionnaire). RESULTS: In total, 4208 respondents with AD (mild AD, 2862; moderate AD, 1177; severe AD, 169) and 4208 respondents without AD were included in this analysis. Results showed greater burden across severity levels compared with matched non-AD controls. A higher proportion of respondents with mild-to-moderate AD, defined by DLQI severity bands, reported atopic comorbidities (P < 0.05) and a wide range of cardiac, vascular, and metabolic comorbidities, including hypertension, high cholesterol, angina, and peripheral vascular disease (P < 0.005), compared with non-AD controls. Relative to potential impacts of various medical and psychological burdens, respondents with mild-to-moderate AD reported higher activity impairment than controls (P < 0.0001). CONCLUSION: Clinical and humanistic burden was observed in European respondents with AD compared with matched non-AD controls across severity levels, with burden evident even in milder disease, highlighting the importance of improving disease management in early stages of AD.
RESUMO
INTRODUCTION: The use of real-world data offers a possibility to perform large-scale epidemiological studies in actual clinical settings. Despite their many advantages, administrative databases were not designed to be used in research, and the validation of diagnoses and treatments in administrative databases is needed. The primary objective of this study was to validate an existing algorithm based on dispensed prescriptions and diagnoses of skin conditions to identify pediatric patients with atopic dermatitis (AD), using a diagnosis of AD in primary care as a gold standard. METHODS: Retrospective observational data were collected from nation-wide secondary care and pharmacy-dispensed medication databases and two regional primary care databases in Sweden. An existing algorithm and a Modified algorithm, using skin-specific diagnoses from secondary care and/or pharmacy-dispensed prescriptions to identify patients with AD, were assessed. To verify the presence of AD, diagnoses from primary care were used in the base case and complemented with diagnoses from secondary care in a sensitivity analysis. RESULTS: The sensitivity (30.0%) and positive predictive value (PPV) (40.7%) of the existing algorithm were low in the pediatric patient population when using primary care data only but increased when secondary care visits were also included in the Modified algorithm (sensitivity, 62.1%; PPV, 66.3%). The specificity of the two algorithms was high in both the base case and sensitivity analysis (95.1% and 94.1%). In the adult population, sensitivity and PPV were 20.4% and 8.7%, respectively, and increased to 48.3% and 16.9% when secondary care visits were also included in the Modified algorithm. CONCLUSION: The Modified algorithm can be used to identify pediatric AD populations using primary and secondary administrative data with acceptable sensitivity and specificity, but further modifications are needed to accurately identify adult patients with AD.
RESUMO
INTRODUCTION: Crisaborole topical ointment, 2%, is a nonsteroidal, topical anti-inflammatory phosphodiesterase-4 (PDE4) inhibitor that is approved for the treatment of mild-to-moderate atopic dermatitis (AD). The objective of the current analysis was to compare the efficacy of crisaborole 2% relative to pimecrolimus 1%, tacrolimus 0.03% and tacrolimus 0.1% in patients aged ≥ 2 years with mild-to-moderate AD by comparing improvement in Investigator's Static Global Assessment scores ( (ISGA scores of 0/1 indicating "clear or almost clear"). ISGA was selected as the primary efficacy outcome given the US Food and Drug Administration's recommendations on the use of ISGA for assessment of global severity in AD and to align with efficacy measurements in the crisaborole registration trials. Safety endpoints could not be analyzed due to differences in outcome definitions across studies. METHODS: Efficacy of crisaborole was evaluated using individual patient data (IPD) from two pivotal phase III randomized controlled trials (RCTs), and efficacy of comparators was evaluated using published RCTs included in a previous network meta-analysis. Vehicle controls were not comparable due to differences in ingredients and population imbalance and, therefore, an unanchored matching-adjusted indirect comparison (MAIC) was used, which reweighted IPD for crisaborole to estimate absolute response in comparator populations. RESULTS: The odds of achieving an improvement in ISGA score was higher with crisaborole 2% versus pimecrolimus 1% (odds ratio [OR] 2.03; 95% confidence interval [CI] 1.45-2.85; effective sample size = 627, reduced from 1021; p value < 0.001) and for crisaborole 2% versus tacrolimus 0.03% (OR 1.50; 95% CI 1.09-2.05; effective sample size = 311, reduced from 1021; p = 0.012). CONCLUSION: The unanchored MAIC suggests that the odds of achieving an improvement in ISGA score is greater with crisaborole 2% than with pimecrolimus 1% or tacrolimus 0.03% in patients aged ≥ 2 years with mild-to-moderate AD. These results are consistent with findings from the previously published network meta-analysis, which used a different methodology for performing indirect treatment comparisons.
RESUMO
INTRODUCTION: The burden of mild-to-moderate atopic dermatitis (AD) in the United Kingdom (UK) is not well understood. Long-lasting AD flares may lead to systemic inflammation resulting in reversible progression from mild to more severe AD. This study aimed to assess the clinical and economic burden of mild-to-moderate AD in the UK. METHODS: AD patients were identified in the Health Improvement Network (THIN) from 2013 to 2017 and propensity score matched to non-AD controls by demographics. Patients were identified based on continuous disease activity using validated algorithms and sufficient patient status to fully validate data integrity for the entire period. Mild-to-moderate AD patients were identified by using treatment as a surrogate. Demographics, clinical characteristics and healthcare resource use (HCRU) were obtained from THIN. Literature reviews were conducted to obtain additional outcomes. A cost-of-illness model was developed to extrapolate the burden in 2017 to the UK population and in subsequent years (2018-2022). RESULTS: In 2017, the prevalence of mild-to-moderate AD in THIN was 1.28%. These patients reported higher comorbidity rates and significantly higher (p < 0.0001) HCRU, encompassing mean general practitioner visits (5.57 versus 3.59), AD-related prescriptions (5.85 versus 0.68) and total referrals (0.97 versus 0.82) versus matched non-AD controls. The model projected total HCRU and drug excess costs of 462.99M over the 5 years. The excess cost decreased to 417.35M after excluding patients on very potent topical corticosteroids, who most likely had at least moderate disease. The excess costs increased to 1.21B and 7.06B when considering comorbidity burden and productivity losses, respectively. CONCLUSION: Mild-to-moderate AD patients had higher comorbidity burden, HCRU and cost compared with matched non-AD controls. Overall, UK country-based economic burden was high given partly the high prevalence of this disease. Moreover, productivity burden and comorbidities had considerable impact on the economic burden, which further suggests the importance of optimal disease management.
RESUMO
INTRODUCTION: Atopic dermatitis (AD) severity was measured in two phase 3 US studies of crisaborole ointment, 2%, in patients aged ≥ 2 years using the Investigator's Static Global Assessment (ISGA), an FDA-recommended scale. Eczema Area and Severity Index (EASI) is a validated scale used globally to assess AD severity in clinical trials. The objective of this study is to aid interpretability of ISGA by translating ISGA scores to EASI scores. METHODS: ISGA was mapped to EASI using published EASI severity strata by Chopra et al. and Leshem et al. and pooled data from phase 3 trials CrisADe CORE 1 and CORE 2, which evaluated crisaborole in patients aged ≥ 2 years with mild-to-moderate AD (crisaborole, n = 1016; vehicle, n = 506). Least squares mean (LSM) percentage change from baseline (%CFB) in EASI and proportion of patients with 50%, 75%, and 90% improvement (EASI-50, EASI-75, and EASI-90, respectively) on day 29 were computed for mapped EASI. The relationship between changes in ISGA and changes in EASI was assessed using data from three abrocitinib trials. RESULTS: ISGA was mapped to EASI using 70,000 random simulations. LSM (standard error) for %CFB in mapped EASI at day 29 (crisaborole versus vehicle) was -26.3% (17) versus 45.2% (35) (P = 0.0671) using Chopra strata and -43.1% (4.6) versus -5.2% (8.4) (P < 0.0001) using Leshem strata. EASI-50, EASI-75, and EASI-90 rates were 72.1% versus 57.6%, 63.0% versus 47.8%, and 55.0% versus 40.1%, respectively, using Chopra strata (P < 0.0001 for each difference). These rates were 68.8% versus 54.0%, 54.8% versus 40.5%, and 38.9% versus 27.2%, respectively (P < 0.0001 for each difference) using Leshem strata. Mean two-point improvement in ISGA was comparable to EASI-90. CONCLUSION: Mapped EASI results were consistent with ISGA results in crisaborole phase 3 trials. Simulation methodologies yielded consistent results and may aid in interpretability of ISGA across clinical studies. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02118766, NCT02118792.
RESUMO
INTRODUCTION: Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin condition characterized by pruritic, eczematous lesions. Recent evidence suggests that AD may be a systemic disorder, implying that management of this disease extends beyond merely controlling symptoms associated with AD. Even though this disease is highly prevalent in children and patients typically present with mild-to-moderate symptoms, the disease burden is not well established. METHODS: A large, retrospective cohort study of Swedish population data was conducted to compare the clinical burden in terms of healthcare resource use and direct medical costs for pediatric mild-to-moderate (pM2M) AD patients (≤ 14 years of age, N = 87,721) with matched controls. The burden of a severe AD cohort was also evaluated. Severity of AD was defined by treatment usage and systemic treatment was used as a proxy for severe AD. A robust approach was used by including any type of secondary care visits known to be more common in AD patients than in the general population; however, data for primary care visits were not available. RESULTS: For healthcare resource use, the incidence rate ratio (pM2M AD versus reference cohort) of secondary care visits ranged from 1.56 to 2.35 during each of 5 years after AD onset (all p < 0.001), with largest differences seen in years 1-2. The average direct medical cost (SD) was 1111 (3416) and 524 (2446) in the pM2M AD and reference cohorts, respectively. The corresponding estimate in the severe AD cohort was 1906 (7067). Including all secondary care visits and pharmacy-dispensed medications, the pM2M AD cohort was shown to have an additional 118.9 million in direct medical costs over 5 years compared with the reference cohort. CONCLUSIONS: This study shows significant clinical and economic burden of pM2M AD with important secondary care resource utilization, suggesting a need for further research to increase treatment options and improve the management of these patients.

RESUMO
INTRODUCTION: There is a need to compare efficacy and safety profiles of crisaborole ointment, 2%, versus other topical treatments across randomized clinical trials (RCTs). We performed this review/network meta-analysis to evaluate the comparative efficacy and safety of crisaborole versus other topical pharmacologic therapies for mild-to-moderate atopic dermatitis (AD) among patients aged ≥ 2 years. METHODS: Searches were conducted in MEDLINE, Embase, the Cochrane Collection Central Register of Clinical Trials, and the Database of Abstracts of Reviews of Effects using Ovid to identify English language articles reporting RCTs of topical anti-inflammatory agents in patients aged ≥ 2 years with mild-to-moderate AD published between inception and 10 March 2020. This review used a prespecified protocol with eligibility criteria for population, interventions, comparisons, outcomes, and study design. Efficacy was evaluated using the Investigator's Static Global Assessment (ISGA) of clear (0) or almost clear (1) and expressed by hazard ratios (HR) with 95% credible intervals. RESULTS: Patients treated with crisaborole or tacrolimus ointment, 0.1% or 0.03%, versus vehicle alone were significantly more likely to achieve ISGA 0/1 at 28-42 days, with the greatest point estimate observed for the crisaborole comparison (hazard ratio: 2.07; 95% credible interval 1.76 to - 2.36; probability HR above 1 [p better]: 100.0%). Patients were also more likely to achieve ISGA 0/1 with crisaborole than with pimecrolimus cream, 1% (HR: 1.62; 95% credible interval 1.04-2.48; p better: 98.3%). While network meta-analysis for safety was not feasible because of data limitations, crisaborole pivotal studies (AD-301/AD-302) showed crisaborole was well tolerated. CONCLUSIONS: Crisaborole was shown to be superior to vehicle and pimecrolimus and comparable to tacrolimus, 0.1% or 0.03%, with respect to ISGA 0/1 at 28-42 days in patients aged ≥ 2 years with mild-to-moderate AD. This evaluation of comparative efficacy of crisaborole further supports use of crisaborole as an effective therapeutic option in this population.
RESUMO
OBJECTIVE: To estimate health-related quality of life (HRQoL) in patients with tuberous sclerosis complex (TSC) and associated manifestations and to identify potential factors associated with HRQoL in this population of patients. METHODS: We performed a retrospective chart review of adults with TSC who attended the outpatient clinic of the University Medical Center Utrecht in the Netherlands from 1990 to 2015 (N = 363; on average 33.6 years of follow-up). HRQoL data were assessed in 2012 using the Health Utility Index version 3 (HUI-3) questionnaire completed by patients or caregivers (N = 214 with HUI score and ≥1 TSC manifestation, including renal angiomyolipomas [rAMLs], subependymal giant cell astrocytoma [SEGA], or epilepsy). RESULTS: Of 214 patients in the study sample, 171 had TSC-associated epilepsy (with or without rAML/SEGA), 37 had TSC and rAML (without epilepsy or SEGA), and 6 had other combinations of manifestations. The median HUI score for the 214 patients with ≥1 TSC manifestation was 0.51 (-0.371 to 1 scale, 1 = perfect health, 0 = death, <0 = worse than death). Among all components used to build the overall HUI score, the cognition component had the lowest score (mean = 0.47; 0-1 scale). Patients with TSC-epilepsy had significantly lower overall HUI than patients with TSC and rAML only (median HUI = 0.31 vs 0.95, P < .05), especially those who were in refractory state for prolonged periods of time (median HUI = -0.11 among patients with seizures during the entire duration of their follow-up time). In multivariate analyses, severe impairment of daily functioning was the strongest predictor of HRQoL decrement (adjusted HUI difference between patients with severe vs. no impairment = -0.55, P < .05). SIGNIFICANCE: This study showed that TSC-related epilepsy is associated with lower HUI, especially for patients who have refractory seizures for prolonged periods of time. Early and effective interventions to control or reduce seizures and preserve patients' cognitive functions may help to improve patients' quality of life.
RESUMO
BACKGROUND: There is limited information on changes over time in carcinoid syndrome (CS) symptoms and quality of life (QoL). This study assessed change in CS symptoms and QoL in patients treated with somatostatin analogs (SSAs) using the Functional Assessment of Cancer Therapy-General (FACT-G) and Patient-Reported Outcomes Measurement Information System (PROMIS)-29 instruments. METHODS: Patients ≥18 years old with CS symptoms and treated with SSA or non-SSA agents in the United States were recruited through a patient advocacy group to complete a two-part, anonymous online survey. Time point (T) 1 survey was fielded from July-October 2016, and T2 survey followed 6 months later. Clinical characteristics and SSA treatment duration were assessed at T1. FACT-G and PROMIS-29 QoL surveys were administered and CS symptoms were assessed at T1 and T2; proportions of patients not experiencing symptoms were compared by McNemar's test. Healthcare resource utilization (HRU) was assessed for the T1-T2 interval, and mean difference in QoL score from T1 to T2 by SSA duration was calculated. RESULTS: Of 117 participants at T1, 89 (76%) completed the T2 survey and served as the study sample; 11 (13%) were treated with SSAs for > 0-2 years, 37 (42%) for > 2-5 years, and 39 (45%) for > 5 years. A higher proportion of patients at T2 vs. T1 reported the following symptoms as not applicable: diarrhea (16% vs. 7%, p < 0.05), flushing (28% vs. 18%, p < 0.05), wheezing (78% vs 66%, p = 0.008). Most patients (89%) had a physical exam and a mean of 7.2 healthcare provider visits between T1 and T2. Patients treated with SSAs for ≤2 years had a mean positive change of 3.7 in their FACT-G total score between surveys, and 6.0 in an additional set of CS-specific questions. Patients receiving SSAs for > 2 years did not appear to associate with a clinically meaningful improvement in QoL score as assessed by FACT-G between T1 and T2; patients also had no clinically meaningful improvement as assessed by PROMIS-29. CONCLUSIONS: There may be clinically important improvement in QoL as measured by FACT-G in patients in earlier years of receiving SSA, which may not appear in later years of SSA treatment.

BACKGROUND: In the phase IIIb PROMID study, octreotide long-acting significantly extended time to tumor progression compared with placebo in treatment-naïve patients with well-differentiated metastatic midgut neuroendocrine tumors. We report post hoc analyses for health-related quality of life (HRQoL). METHODS: HRQoL was measured with EORTC QLQ-C30, a 30-item self-report questionnaire (5 functional, 1 global, 9 symptom scales). Assessments were completed at baseline and every 12 weeks until tumor progression. Time to definitive deterioration (TDD; worsening of ≥10 points without further improvement) was analyzed with the Kaplan-Meier method. Linear mixed models were fit to assess change from baseline in QLQ-C30 scores by treatment arm over time. RESULTS: Among 85 patients, 82 (96%) completed the QLQ-C30 at baseline. There were few events of definitive deterioration for many scales. Significantly longer TDD was reported for long-acting octreotide versus placebo for fatigue (median 18.5 months vs. 6.8; p = 0.0006), pain (not reached [NR] vs. 18.2; p = 0.0435) and insomnia (NR vs. 16.4; p = 0.0046). Change from baseline to week 24 fatigue scores were stable for long-acting octreotide (mean 0.78; 95% CI -6.3 to 7.8) but worsened for placebo (mean 9.1; 95% CI 1.9-16.4), and for diarrhea there were improvements for long-acting octreotide (mean -8.0; 95% CI -19.6 to 3.5) and worsening for placebo (mean 11.2; 95% CI -0.7 to 23.1). CONCLUSIONS: HRQoL was maintained with few deteriorations in long-acting octreotide patients, whereas there was earlier and/or more deterioration in placebo patients. In long-acting octreotide patients, HRQoL was maintained or improved for the clinically important neuroendocrine tumor symptoms such as fatigue, insomnia, diarrhea and pain, whereas placebo patients experienced a deterioration of HRQoL scores for these symptoms.

BACKGROUND: Using data from four tertiary referral centers in the U.S., we assessed real-world treatment patterns and clinical outcomes of patients with advanced lung neuroendocrine tumors (NETs). SUBJECTS, MATERIALS, AND METHODS: We performed a retrospective chart review of adult patients with locally advanced/metastatic (typical/atypical) lung NETs treated between July 2011 and December 2014. Index date was histologically confirmed typical/atypical carcinoid tumor diagnosis date. Data included baseline characteristics, treatment patterns, progression, death, and lung NET-related health care resource use from index date through last contact/death. Time to treatment discontinuation and first progression, time from first to second progression, and overall survival (OS) were estimated using Kaplan-Meier analysis. RESULTS: We identified 83 patients; 19 (23%) had functional NET. First-line treatments included somatostatin analogs (SSAs) alone (56%) or in combination with other therapies (6%), cytotoxic chemotherapy (20%), external beam radiation therapy (EBRT) (9%), liver-directed therapy (LDT) (4%), and everolimus/other (5%). Sixty patients had second-line therapy including SSA alone (18%) or in combination (40%), cytotoxic chemotherapy (17%), everolimus (12%), LDT (7%), EBRT (3%), and other treatments (3%). Median time (months) to first-line discontinuation were as follows: SSAs, 43.3; cytotoxic chemotherapy, 3.6. Overall median time (months) to investigator-assessed progression following treatment initiation was 12.4. Median OS (months) following treatment initiation was 66.4 for all patients and 81.5 for patients receiving SSAs. CONCLUSION: SSAs, alone and in combination, are common treatments for advanced lung NETs. Patients have additional treatment options and relatively long survival compared with patients with other advanced cancers. Treatment pattern assessment following approval of newer treatments is needed. IMPLICATIONS FOR PRACTICE: Somatostatin analogs (SSAs), cytotoxic chemotherapy, EBRT, liver-directed therapy, and targeted therapies are common treatments for locally advanced/metastatic (typical/atypical) lung neuroendocrine tumors (NETs). SSAs alone or in combination with other treatment modalities were the most common first- and second-line therapy, followed by cytotoxic chemotherapy. Patients continued treatment with SSAs long-term with median treatment duration of 43 months. Median overall survival was 66 months following initiation of first-line therapy for all patients. Treatment pattern assessment beyond the time period of this study is needed given recent U.S. Food and Drug Administration approvals for additional treatments for lung NETs that will likely be incorporated in the treatment landscape.

BACKGROUND: We assessed treatment patterns and outcomes of patients with advanced gastrointestinal (GI) neuroendocrine tumors (NET) at four large tertiary referral centers in the U.S. PATIENTS AND METHODS: We performed a retrospective chart review of patients aged ≥18 years at advanced GI NET diagnosis, treated between July 2011 and December 2014. Index date was the histologically confirmed diagnosis date of locally advanced/metastatic GI NET. Data included baseline characteristics, treatment patterns, progression, death, and GI NET-related health care resource utilization from index date through last contact or death. Time-to-event analyses, including treatment discontinuation, progression, and overall survival (OS), were performed using Kaplan-Meier analysis. RESULTS: We identified 273 patients; 156 (57%) had primary ileum NET, and 174 (64%) had functional NET. First-line treatments included somatostatin analog (SSA) alone (89%) or in combination (2%), liver-directed therapy (LDT; 8%), and cytotoxic chemotherapy or interferon (2%). One hundred fifty-five patients continued with second-line therapy, including SSA alone (17%) or in combination (75%, with 3% combined with peptide receptor radionuclide therapy), LDT (4%), and other treatments (3%). Median time (months) to first-line discontinuation was 154.0 for SSAs and 3.8 for cytotoxic chemotherapy. Overall median time to investigator-assessed progression following treatment initiation was 30.3 months. Median OS (months) following first-line initiation was 151.8 for all patients and 178.9 for first-line SSA. CONCLUSION: Our study illustrates the common use of SSAs in both first-line and subsequent treatment of patients with GI NETs, as well as the relatively long survival durations and multiple additional treatments received by patients with this condition. Treatment pattern assessment at later times, following approval of newer treatments, is warranted. IMPLICATIONS FOR PRACTICE: This study, assessing treatment patterns over a period of up to 30 years, showed that SSAs, LDT, cytotoxic chemotherapy, and interferon are common treatments for advanced GI NETs. SSAs alone or in combination with other treatments were the most frequent therapy in first and subsequent lines. Patients in this study remained on SSAs long-term, with median treatment duration of 12.8 years in first line. Treatment patterns should be assessed beyond this study's time period, given recent U.S. Food and Drug Administration approvals for additional treatments for GI NET, which will likely be incorporated in the continuum of care of patients.

To evaluate association of carcinoid syndrome (CS) symptom burden and somatostatin analog (SSA) duration with quality of life (QoL) using Functional Assessment of Cancer Therapy-General (FACT-G) and Patient-Reported Outcomes Measurement Information System (PROMIS-29) instruments.Adults who received treatment for CS symptoms in the US were recruited to participate in a cross-sectional online survey (July-October, 2016). Demographic, clinical, and QoL questions (FACT-G, 29 CS-related supplemental questions, PROMIS-29) were included. Descriptive and multivariable regression analyses adjusting for demographic and clinical characteristics followed.Most (98%) of the 117 patients received SSAs in the prior month. Multivariable regression analysis showed ≥4 bowel movements/day (vs <4) and each additional CS symptom was associated with 7.1 (Pâ=â.043) and 3.4 (Pâ=â.034) point FACT-G total score decreases, respectively. Requiring bed rest (vs normal activity) was associated with significant decreases in FACT-G total score (Pâ<â.001). There were similar associations for FACT-G subscales, supplemental questions, and PROMIS-29. After adjustment, FACT-G total score was significantly higher (11.3 points; Pâ=â.033) for patients treated with SSA >8 years versus <2.7 years.CS symptom burden was observed to be associated with lower QoL scores, measured by FACT-G. Patients with >8 years SSA treatment duration versus <2.7 years had higher QoL.

OBJECTIVE: To compare kidney size (used as proxy for total renal angiomyolipoma [rAML] size) and kidney function outcomes between patients with tuberous sclerosis complex (TSC) and rAML treated and not treated with everolimus. METHODS: Medical charts of adults with TSC-associated rAML followed at a specialty medical center in the Netherlands (1990-2015). Included patients treated with everolimus (n = 33, of which 27 were included in the kidney size analyses and 27 in the kidney function analyses [21 patients in both]; index date = everolimus initiation) and non-treated patients (n = 39, of which 29 were included in the kidney size analyses and 33 in the kidney function analyses [23 patients in both]; index date = one date among all dates with outcome measurement).Percent change in kidney size and kidney function from the index date to the best measurement in the two years post-index date (best response) compared between patients treated and not treated with everolimus. RESULTS: Compared with non-treated patients, significantly more everolimus-treated patients experienced a reduction in the size of their largest kidney in the two years post-index date (85.2% vs. 37.9%, p < 0.01). Also, there was a tendency towards more improvement in the estimated glomerular filtration rate (eGFR) among the everolimus-treated patients (55.6% vs. 33.3%, p = 0.08). CONCLUSIONS: The study results suggest that everolimus is effective in controlling and even reversing the growth of the kidneys, used as a proxy for rAML size, as well as preserving or improving kidney function in patients with TSC and rAML treated in a real-world, observational setting.

BACKGROUND: As reported in Surveillance, Epidemiology, and End Results (SEER) data, US incidence and prevalence of neuroendocrine tumors (NET) has increased over recent years. The study objective was to update incidence and prevalence information for lung NET using administrative claims. METHODS: This descriptive epidemiological study used 2009-2014 data from 2 US claims databases: MarketScan and PharMetrics. Patients (18-64 years old) had ≥1 inpatient or ≥ 2 outpatient claims with NET of bronchus or lung, identified by International Classification of Diseases, 9th Revision, Clinical Modification diagnosis codes. Prevalence was number of lung NET patients divided by number of enrollees/year. Incidence was number of patients with a first observed NET diagnosis who were disease-free for 2 years prior, divided by number of enrollees. Age and gender adjustments performed. RESULTS: The annual number of patients with lung NET identified from 2009 to 2014 ranged from 435 to 796 (MarketScan) and 419-648 (PharMetrics). In MarketScan, there was a 7.4% (95%CI 2.1-13.0; p = 0.027) annual percent change (APC) in the age-adjusted incidence for males and 6.8% (- 0.2-14.3; 0.052) for females. In PharMetrics, APC was - 2.9% (- 13.8-9.4; 0.395) for males; 14.7% (- 12.9-51.2; 0.165) for females. In MarketScan, APC in age-adjusted prevalence for males was 9.9% (4.7-15.3; 0.006); 16.2% (11.4-21.1; <.001) for females. For PharMetrics, APCs were 9.5% (2.3-17.2; 0.021) for males; 16.3% (9.6-23.5; 0.002) for females. CONCLUSIONS: From 2009 to 2014 there was a statistically significant increase in age-adjusted lung NET incidence for males in MarketScan, and a statistically significant increase in age-adjusted prevalence for both genders in PharMetrics. Incidence and prevalence changes, to the extent they exist, may be due to better diagnostic methods, increased awareness of NET among clinicians and pathologists, and/or an actual increase in US disease occurrence. Differences in rates across databases are difficult to explain. These results suggest the need for awareness of the clinically effective and safe treatment options available for lung NET patients among healthcare providers.
