RESUMO
Aim: To describe real-world treatment patterns/outcomes among patients with HER2+ metastatic breast cancer (MBC). Materials & methods: Real-world treatments and overall survival (OS) were evaluated among adult women diagnosed with HER2+ MBC, with and without brain metastases (BMs), between 1 June 2012 and 31 May 2018 using electronic medical records from the Definitive Oncology Dataset. Results: Among 372 patients, 69% initiated first-line trastuzumab plus pertuzumab-based therapy; many therapy combinations were utilized in the second- to fourth-line. During follow-up (median 24.8 months), 18% of patients died (22% with and 16% without BMs). Mean OS was shortest among patients with BMs at MBC diagnosis in the third- and fourth-line. Conclusion: OS was poor, and no clear standard of care was observed among patients with HER2+ MBC progressing on trastuzumab-based therapies.

OBJECTIVE: There is no standard systemic treatment for recurrent or metastatic cervical cancer (r/mCC) after failure of first-line (1L) therapy. This study characterizes the patient experience, treatment patterns, and clinical outcomes of patients who initiated second-line (2L) therapy for r/mCC in a US community oncology setting. METHODS: This is an observational study of cervical cancer patients who failed 1L systemic treatment for r/mCC and initiated 2L systemic therapy between 2014 and 2019 within the US Oncology Network (USON). USON's electronic health records were used to identify eligible patients and abstract data. Overall survival (OS), time to treatment discontinuation (TTD), and time to first subsequent treatment (TFST) were estimated using Kaplan-Meier methods. RESULTS: A total of 130 patients were identified (mean age 53 years). Over 60% of patients had Eastern Cooperative Oncology Group score of 0-1. Cytotoxic monotherapy was the most frequently prescribed regimen (N = 60, 46%) in 2L, followed by combination therapies (N = 45, 35%), pembrolizumab monotherapy (N = 19, 15%), and bevacizumab monotherapy (N = 6, 5%). Median OS was 9.1 months (95% CI: 7.2-12.2) after initiation of 2L therapy. Median TTD was 2.8 months (95% CI: 2.5-3.3), and median TFST was 4.9 months (95% CI: 4.2-5.7). No significant difference in outcomes was found when stratified by 2L treatments. CONCLUSIONS: The observed heterogeneity in 2L r/mCC therapy suggests no clear standard-of-care in this setting. Additionally, short duration of OS observed was consistent across 2L regimens. New, effective treatment options in this setting are needed.

OBJECTIVES: Liposomal irinotecan (nal-IRI) is a topoisomerase inhibitor proven to improve survival in metastatic pancreatic cancer (mPC). This study describes real-world characteristics of patients treated with nal-IRI for mPC. METHODS: Patients 18 years or older diagnosed with stage IV mPC and treated with nal-IRI were selected retrospectively from a deidentified electronic health record database of more than 2 million US cancer patients. Demographics, clinical and dosing characteristics, and treatment outcomes were collected. RESULTS: Of 257 total patients, 145 (57%) received nal-IRI as first- or second-line therapy. Median nal-IRI treatment duration was 51 days, longer when nal-IRI was used as first/second versus as third-line therapy or later (62 vs 44.5 days). Seventy patients (27.2%) experienced dose modification. Median time to treatment discontinuation was 2.3 versus 1.6 months for first-/second- versus third-line therapy or later, respectively. Median overall survival from nal-IRI initiation was 5.6 versus 4.1 months for first-/second- versus third-line therapy or later, respectively. Prior irinotecan treatment, baseline serum albumin less than 40 g/L, and baseline neutrophil-to-lymphocyte ratio greater than 5 were associated with reduced overall survival. CONCLUSIONS: This is the first large US study of real-world US mPC patients treated with nal-IRI. These results, comparable to the NAPOLI-1 trial, can help inform future studies and the efficacy of nal-IRI in mPC therapy.

BACKGROUND: Although an increasing number of treatments have become available for patients with advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs), there remains little consensus on treatment sequence and its impact on health care resource use (HRU). We sought to describe treatment patterns and HRU, in a cohort of patients with metastatic GEP-NETs treated at a tertiary referral center in the U.S. MATERIALS AND METHODS: We identified patients with a well-differentiated, metastatic GEP-NET evaluated at Dana-Farber Cancer Institute between July 2003 and May 2015. For these patients, we describe the sequence of treatment regimens received for their disease, together with associated HRU. RESULTS: We identified 682 patients with advanced GEP-NETs. Of these patients, 597 (87.0%) initiated ≥1 treatment over the follow-up period. The mean age at diagnosis was 58.5 years, 50.2% were men, and 94.0% were white. A total of 83.1% initiated a somatostatin analog (SSA) as their first-line treatment, with 55% and 31% of patients continuing with second- and third-line therapies. A total of 31.2% of patients with SSAs underwent dose escalation to above standard dose. In this setting, patients with pancreatic neuroendocrine tumors were more commonly treated with cytotoxic regimens than other NET tumor types and also had higher HRU. CONCLUSION: Our study suggests that, at a tertiary referral center, patients with advanced NETs commonly received multiple courses of treatments. Our data suggest a clear preference for use of SSAs as a first-line treatment for patients with advanced NETs, with SSAs commonly escalated and continued throughout the course of treatment in combination with other regimens. IMPLICATIONS FOR PRACTICE: The current study demonstrates the common use of somatostatin analog as a first-line therapy for patients with advanced gastroenteropancreatic neuroendocrine tumors as well as the incorporation of multiple different treatment regimens in the treatment course of patients with this disease.

PURPOSE: To understand the quality of life (QoL) for patients with neuroendocrine tumors (NETs) through comparison of QoL questionnaires and symptom tracking as well as journaling via the Carcinoid NETs Health Storylines mobile application (app). PATIENTS AND METHODS: This was a 12-week prospective, observational study of US patients with NET who were taking long-acting somatostatin analogs. National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) and European Organisation for Research and Treatment of Cancer (EORTC) questionnaires were administered three times. Patients also monitored symptoms, mood, bowel movements, food, activity, and sleep, and they journaled in their app, which was coded by theme and sentiment for qualitative analysis. RESULTS: Of the 120 patients with NET, 78% were women (mean age, 57 years); 76% had gastroenteropancreatic NETs, and 88% had metastases. Lanreotide depot and octreotide long-acting release (LAR) were used by 41% and 59%, respectively. The most common symptoms at baseline were fatigue (76.7%), diarrhea (62.5%), abdominal discomfort (64.1%), and trouble sleeping (57.5%). The majority completed five of six survey assessments (median, 5; mean, 5.1) and tracked four symptoms in the app (median, 4; mean, 5.5); the average frequency was 41.6 days for each symptom (median, 43; mean, 41.6; range, 1 to 84 days [12 weeks]). Without treatment change, most EORTC-assessed physical symptoms decreased from baseline to midpoint (eg, 59.3% at baseline v 33% at midpoint reported "quite a bit" or "very much" diarrhea; P = .002). App-based symptom tracking revealed large day-to-day variation, but weekly averages correlated well with survey scores. Journal entries showed that more patients made predominantly negative unsolicited entries about their injection experience with octreotide LAR compared with lanreotide (13 of 17 v two of 13; P < .001). CONCLUSION: Patients with NET experience a large symptom burden that varies daily. A decrease in physical symptoms on QoL surveys suggests an effect from daily app-based monitoring or journaling, which may reduce recall bias and benefit the patient's experience of symptoms.

BACKGROUND: Although recent pivotal trials (PROMID, CLARINET) have established somatostatin analogs (SSAs) as first-line agents for neuroendocrine tumors (NETs), their use in clinical practice is largely unknown. We aimed to understand real-world management and treatment of gastroenteropancreatic (GEP) NETs. MATERIALS AND METHODS: Patients with metastatic GEP-NETs treated with SSAs, lanreotide depot or octreotide long-acting release (LAR), between January 1, 2015, and December 31, 2015, were identified from a U.S. claims database supplemented with chart review for a subset of patients. Descriptive statistics summarized patients' demographics, clinical characteristics, treatment patterns, and healthcare resource use. Univariate and multivariate comparisons were made across SSA groups. RESULTS: Among 548 patients treated with an SSA for metastatic GEP-NET (lanreotide = 108; octreotide = 440), demographic and clinical characteristics were similar across groups, except more patients with pancreatic NETs were treated with lanreotide (38.7% vs. 6.3%, p < .01). More octreotide patients had a diagnosis of carcinoid syndrome compared with lanreotide patients (19.8% vs. 11.1%, p = .02). Approximately 1.1% of patients received lanreotide (>120 mg every 4 weeks [Q4W]) at a dose above label compared with 12.7% of octreotide patients (>30 mg Q4W; p < .01). At 1.5 years after SSA initiation, 85.7% (95% confidence interval, 74.3%-92.3%) were still on index SSA as reported by the physician. Variances between chart review and claims data were significant. CONCLUSION: SSAs were common in first-line systemic intervention, but dose escalations and dosing deviations outside of label were noted. Variances between claims and chart review warrant additional research to compare methodologies. With an increasing focus on value-based care in oncology, it is critical to understand the use of, and outcomes with, these agents in community practices. IMPLICATIONS FOR PRACTICE: The aim of this study was to enhance understanding of real-world management and treatment of metastatic neuroendocrine tumors (NETs), with particular focus on systemic therapy with a somatostatin analog (SSA). As per published guidelines, SSAs are common in first-line systemic intervention, but dose escalations and dosing deviations outside of the label are noted for symptom control. Nevertheless, oncologists must weigh the implications of the use of above-label dosing of SSAs to manage and treat patients with metastatic NET within a value-based care framework.

PURPOSE: Metastatic neuroendocrine tumors (mNETs) are rare, heterogeneous tumors that present diagnostic and treatment challenges, with limited data on the management of mNETs in clinical practice. The present study was designed to identify current diagnostic and treatment patterns in mNET patients treated in the US community oncology setting. METHODS: Patient-level data was collected from medical records of adults with mNETs from the Vector Oncology Data Warehouse, a comprehensive US community oncology network database. RESULTS: Of the 263 patients included (median follow-up, 22 months; range, 0.1-193.9), 30.4% (80/263) had intestinal tumors, 11.0% (29/263) had pancreatic, and 58.6% (154/263) had tumors of other or unknown location. Progression-free survival (PFS) from the start of first-line therapy differed significantly by tumor grade (log rank P = 0.0016) and location (P = 0.0044), as did overall survival (OS) (grade, P < 0.0001; location, P = 0.0068). Median PFS and OS for patients with undocumented tumor grade were shorter than for patients with G1/G2 tumors and longer than patients with G3 tumors. Median PFS and OS for patients with other or unknown tumors were shorter than for patients with intestinal tumors. CONCLUSIONS: While potentially confounded by the high number of patients with other or unknown tumor locations, this retrospective study of patients in a US community oncology setting identified the importance of awareness of tumor grade and tumor location at diagnosis, as these were direct correlates of PFS and OS.

OBJECTIVE: This study was conducted to understand treatment patterns and clinical outcomes in metastatic gastroenteropancreatic neuroendocrine tumor patients treated in a large community oncology network. METHODS: This retrospective study used the McKesson Specialty Health/US Oncology Network iKnowMed electronic health record database with supplemental chart review. Eligibility criteria included a metastatic neuroendocrine tumor diagnosis between January 1, 2008, and to December 31, 2012; at least 2 US Oncology Network visits; and age at least 18 years. Follow-up was through October 31, 2014. RESULTS: Among the 229 patients identified, median age was 64.0 years, 52.4% were male, 69.4% were white, and 62.9% were overweight/obese. Primary tumor sites included small bowel (47.6%), pancreas (31.4%), and stomach/colorectum (21.0%). There were 16.2% under observation without treatment, 52.4% received only somatostatin analogs (SSAs), and 31.4% received chemotherapy/targeted therapy during treatment. In the first-line setting (n = 192), 77% received SSAs, 12% received chemotherapy, and 10.9% received targeted therapy. Fifty percent of patients receiving octreotide had a relative dose intensity of less than 85%, and 16.7% received above-label dose. Toxicities of SSAs included diarrhea (18.2%), abdominal pain (16.9%), and fatigue (13.5%). Median overall survival from diagnosis was 68.0 months (95% confidence interval, 57.1 to not reached). CONCLUSIONS: Most metastatic gastroenteropancreatic neuroendocrine tumor patients received systemic treatment with SSAs. Patient treatment used an individualized dosing approach. Overall survival and toxicity were consistent with the published literature.

OBJECTIVE: With the introduction of new therapies, hospitals have to plan spending limited resources in a cost-effective manner. To assist in identifying the optimal treatment for patients with locally advanced or metastatic gastroenteropancreatic neuroendocrine tumors, budget impact modeling was used to estimate the financial implications of adoption and diffusion of somatostatin analogs (SSAs). PATIENTS AND METHODS: A hypothetical cohort of 500 gastroenteropancreatic neuroendocrine tumor patients was assessed in an economic model, with the proportion with metastatic disease treated with an SSA estimated using published data. Drug acquisition, preparation, and administration costs were based on national pricing databases and published literature. Octreotide dosing was based on published estimates of real-world data, whereas for lanreotide, real-world dosing was unavailable and we therefore used the highest indicated dosing. Alternative scenarios reflecting the proportion of patients receiving lanreotide or octreotide were considered to estimate the incremental budget impact to the hospital. RESULTS: In the base case, 313 of the initial 500 gastroenteropancreatic neuroendocrine tumor patients were treated with an SSA. The model-predicted per-patient cost was US$83,473 for lanreotide and US$89,673 for octreotide. With a hypothetical increase in lanreotide utilization from 5% to 30% of this population, the annual model-projected hospital costs decreased by US$488,615. When varying the inputs in one-way sensitivity analyses, the results were most sensitive to changes in dosing assumptions. CONCLUSION: Results suggest that factors beyond drug acquisition cost can influence the budget impact to a hospital. When considering preparation and administration time, and real-world dosing, use of lanreotide has the potential to reduce health care expenditures associated with metastatic gastroenteropancreatic neuroendocrine tumor treatments.
RESUMO
BACKGROUND: Cushing's disease (CD) is a rare disorder of chronic hypercortisolism due to an adrenocorticotropic hormone (ACTH)-secreting pituitary corticotroph adenoma. Because hypercortisolism symptoms are wide ranging, it is important to assess a variety of outcomes including both clinical factors, such as cortisol levels, and health-related quality of life (HR-QOL), to better understand the severity and impact of CD on patients and the potential efficacy of CD treatment. Pasireotide, a somatostatin analog that targets somatostatin receptors on the pituitary adenoma, is under development as a treatment for CD. A phase III clinical trial was conducted to investigate its safety and efficacy in patients with CD. In this trial, HR-QOL was assessed with the Cushing's Quality-of-Life (CushingQOL) questionnaire, specifically developed and validated in patients with Cushing's syndrome. OBJECTIVE: Reliability, validity, the ability to detect change, and a minimal important difference (MID) were evaluated for the CushingQOL questionnaire using data from patients diagnosed with CD who participated in the phase III clinical trial designed to assess the safety and efficacy of different doses of pasireotide. METHODS: Adult patients (n = 162) with CD participated in a randomized, double-blind, multinational, phase III clinical trial. Patients received subcutaneous pasireotide (600 µg or 900 µg) twice daily for 3 months (double blind). After 3 months, some patients were unblinded based on their mean urinary free cortisol (mUFC) levels and were given the chance to increase their dosage, while the other patients remained blinded. At month 6, an open-label 6-month period began. The CushingQOL questionnaire was self-administered four times (baseline [n = 160], and at months 3 [n = 134], 6 [n = 113], and 12 [n = 76]). A confirmatory factor analysis (CFA) was conducted. Reliability estimates were calculated for internal consistency (coefficient alpha) and test retest (intraclass correlation coefficients [ICCs]) for patients with stable hypercortisolism at month 3 and month 6. Construct validity hypotheses (correlations), mean differences in known groups (ANOVAs), and responsiveness effect sizes (Guyatt's) were estimated based on measures of cortisol, body mass index (BMI), waist circumference, weight, facial rubor (redness), striae (stretch marks), bruising, supraclavicular fat pad, dorsal fat pad, and results of the Beck Depression Inventory II (BDI-II). The half-standard deviation distribution method was used to estimate MID. RESULTS: CFA loadings supported a one-factor solution for the CushingQOL questionnaire items. Internal consistency reliability (0.87-0.88) and ICCs (0.87) were high. Construct validity hypotheses were in the anticipated direction. Changes in CushingQOL scores were moderately correlated with changes in mUFC levels, in BMI, and in weight. Mean scores for minimally depressed patients were significantly higher (indicating better HR-QOL) than for severely depressed patients. Moderate Guyatt's responsiveness effect sizes were observed for patients who achieved reductions in weight, BMI, and waist circumference. Using the half-standard deviation method, an estimate of the MID was computed as 10.1. CONCLUSIONS: This study provided evidence within the context of a longitudinal design that the CushingQOL questionnaire is a reliable, valid, and responsive instrument for the assessment of HR-QOL in adults with CD in accordance with recommendations set forth by regulatory agencies in the USA and Europe.

OBJECTIVE: To assess health care costs associated with Cushing disease and to determine changes in overall and comorbidity-related costs after surgical treatment. METHODS: In this retrospective cohort study, patients with Cushing disease were identified from insurance claims databases by International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes for Cushing syndrome (255.0) and either benign pituitary adenomas (227.3) or hypophysectomy (07.6×) between 2004 and 2008. Each patient with Cushing disease was age- and sex-matched with 4 patients with nonfunctioning pituitary adenomas and 10 population control subjects. Comorbid conditions and annual direct health care costs were assessed within each calendar year. Postoperative changes in health care costs and comorbidity-related costs were compared between patients presumed to be in remission and those with presumed persistent disease. RESULTS: Of 877 identified patients with Cushing disease, 79% were female and the average age was 43.4 years. Hypertension, diabetes mellitus, and hyperlipidemia were more common among patients with Cushing disease than in patients with nonfunctioning pituitary adenomas or in control patients (P<.01). For every calendar year studied, patients with Cushing disease had significantly higher total health care costs (2008: $26 440 [Cushing disease] vs $13 708 [nonfunctioning pituitary adenomas] vs $5954 [population control], P<.01). Annual outpatient costs decreased significantly for patients in remission after surgery, and there was a trend towards improvement in overall disease-related costs with remission. A significant increase in postoperative health care costs was observed in those patients not in remission. CONCLUSIONS: Patients with Cushing disease had more comorbidities than patients with nonfunctioning pituitary adenomas or control patients and incurred significantly higher annual health care costs; these costs decreased after successful surgery and increased after unsuccessful surgery.
