A prospective observational study of patient-reported functioning and quality of life in advanced and metastatic breast cancer utilizing a novel mobile application.

PURPOSE: To assess and describe patient-reported outcomes (PROs) in women with locally advanced/unresectable or metastatic breast cancer (aBC/mBC) with hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR + /HER2 -) status receiving palbociclib combination therapy in a US real-world setting. METHODS: A prospective, noninterventional, multicenter longitudinal study was conducted in US patients initiating treatment with palbociclib combination therapy for HR + /HER2 - aBC/mBC. PRO data (SF-12; CES-D-10; mood; pain; fatigue; interference of aBC/mBC or its treatment on family life, social life, physical activity, energy, and productivity; overall health rating; and quality of life [QOL]) were collected via a custom-developed mobile application at daily, weekly, and cycle-based intervals. Patient medical information (demographics, clinical characteristics, treatment information, and adverse events) was collected from medical records at baseline and at the end of the 6-month follow-up period. RESULTS: Patients' general health status (SF-12) remained consistent throughout treatment and was generally consistent with published norms for individuals diagnosed with cancer. The presence of depression (CES-D-10) was low and did not change substantially over time. Mean pain and fatigue scores using an 11-point numeric rating scale were low and remained stable. Patients, on average, reported neutral or positive moods. Patient-reported QOL and overall health was primarily "Good," "Very good," or "Excellent." Findings were consistent regardless of patient experience with neutropenia. CONCLUSIONS: Patients treated with palbociclib, on average, reported consistently low levels of pain and fatigue as well as good QOL and overall health that remained stable throughout the first 6 months of treatment regardless of episodes of neutropenia.

Physician and Patient Knowledge of Safety and Safe Use Information for Aflibercept in Europe: Evaluation of Risk-Minimization Measures.

BACKGROUND: As part of the risk-management plan for aflibercept in the European Union, materials have been developed to educate physicians and patients in Europe on the safe use of aflibercept. OBJECTIVES: The objectives of this study were to measure receipt of the educational materials and to evaluate understanding of key safety information for aflibercept. METHODS: An observational cross-sectional study among physicians and patients with recent aflibercept experience in France, Germany, Italy, Spain, and the UK was conducted. Eligible physicians and patients completed a brief questionnaire regarding their knowledge of key safety information. RESULTS: Among the 8424 physicians invited to participate in the survey, 428 physicians were eligible, completed the questionnaire, and were included in this analysis. Most physicians reported having received the aflibercept summary of product characteristics (87%) and prescriber guide (77%); approximately half reported receiving the injection procedure video (50%) and patient booklet (54%). Physician knowledge of the most important topics (i.e., side effects; preparing patients for aflibercept injection) was high. Physician knowledge of dosing was high for neovascular (wet) age-related macular degeneration and lower for less commonly prescribed indications. Most physicians knew the contraindications for aflibercept and recognized possible side effects. Among the 874 patients approached about participation in the study, 773 patients were eligible, completed the questionnaire, and were included in the analysis. Patients' reported receipt was relatively low for the aflibercept patient booklet (38%) and the audio CD (23%). Patient knowledge of the health conditions to discuss with a doctor prior to injection was generally high; knowledge about possible side effects varied. Most patients knew that they should speak to a physician immediately if they experienced a possible side effect of aflibercept. CONCLUSION: Most physicians reported receiving the summary of product characteristics, prescriber guide, and patient booklet; half reported receiving the intravitreal injection procedure video. Patient receipt of the educational material was variable. Observed patterns of knowledge indicated the greatest knowledge of the most important risks emphasized in the educational material and lower knowledge of more complex or less salient aspects of safe use.

Evaluation of Physician Knowledge of the Key Safety Information for Aflibercept in Canada: Evaluation of Risk-Minimization Measures.

BACKGROUND: As part of the risk-management plan (RMP) for aflibercept, materials have been developed to educate physicians in Canada on the key safety information and safe use for aflibercept. OBJECTIVE: The objectives of this study were to assess whether physicians in Canada received and reviewed the aflibercept educational materials (i.e. vial preparation instruction card, intravitreal injection procedure video, and product monograph) and to evaluate their knowledge of key safety information. METHODS: Retinal specialists and ophthalmologists who prescribe and/or administer aflibercept were recruited to complete a survey. Physicians could complete and return a paper questionnaire by mail or complete the questionnaire online via a study website. RESULTS: Of the 308 physicians invited to participate in the survey, 95 (31%) completed the questionnaire. Nearly all physicians (98%) reported receiving at least one of the educational materials. The proportion of correct responses to individual questions on storage and preparation of aflibercept ranged from 54 to 98%. Physician knowledge was high on the recommended dose of aflibercept (91%), dose preparation (91-96% on individual items), and dosing guidelines (75-95% on individual items). Most physicians knew the contraindications for aflibercept (89%) and that aflibercept should not be used in pregnancy unless clearly indicated by medical need in which benefits outweigh risks (60%); 21% responded more conservatively that aflibercept should never be used in pregnancy. Knowledge was high for most questions about injection procedures (91-99% on individual items); however, fewer physicians (24%) correctly reported that the eye should be covered with a sterile drape. Knowledge was high for possible side effects (89-100% on individual items) and actions to take in relation to the potential for increased intraocular pressure (86-93% on individual items). CONCLUSION: Nearly all physicians (98%) reported having received the product monograph, and most (82%) reported having received the vial preparation instruction card; nearly half (46%) reported having received the intravitreal injection procedure video. Physicians' knowledge of the most important topics was high. Knowledge varied for topics that are less frequently encountered (e.g. use in women of childbearing potential) and for recommendations that are not standard medical practice in Canada (e.g. use of sterile drape).

Adjuvant treatment patterns and outcomes in patients with stage IB-IIIA non-small cell lung cancer in France, Germany, and the United Kingdom based on the LuCaBIS burden of illness study.

OBJECTIVES: To inform health-technology assessments of new adjuvant treatments, we describe treatment patterns in patients with complete resection of stage IB-IIIA non-small cell lung cancer (NSCLC) in France, Germany, and the United Kingdom (UK). MATERIALS AND METHODS: Data were collected via medical record abstraction. Patients were aged ≥18 years with completely resected stage IB-IIIA NSCLC, diagnosed between 01 January 2009 and 31 December 2011. Median follow-up was 26 months. Adjuvant treatment patterns and clinical outcomes were summarized descriptively. RESULTS: Among the 831 patients studied, 239 (29%) had stage IB disease, 179 (22%) had stage IIA disease, 165 (20%) had stage IIB disease, and 248 (30%) had stage IIIA disease. Adjuvant systemic therapy was received by 402 patients (48.4%), (France, 61.8%; Germany, 51.9%; UK, 33.4%). Use of adjuvant therapy increased with increasing stage of disease. Cisplatin/vinorelbine and carboplatin/vinorelbine were the most frequently prescribed adjuvant regimens. Median disease-free survival was 48.0 months (95% confidence interval [CI] 42.3-not estimable); the 25th percentile was 13.2 months (95% CI, 11.0-15.3). 204 patients (24%) died during the follow-up period. The median overall survival was not reached, the 25th percentile was 31.2 months (95% CI 26.8-36.0 months). 272 patients (33%) had disease recurrence during the follow-up period. For 86 of those patients, the first recurrence was local or regional with no distant metastasis and 14 had further progression to metastatic disease during the follow-up time. For the other 186 patients, the first recurrence involved distant metastases. A total of 200 patients had metastatic disease at any time during study follow-up. CONCLUSIONS: Less than half the patients with stage IB-IIIA NSCLC in this observational study received adjuvant systemic therapy. A high rate of first recurrence with distant metastatic disease was observed, emphasising the need for more effective systemic adjuvant therapies in this population.

Economic burden of resected (stage IB-IIIA) non-small cell lung cancer in France, Germany and the United Kingdom: A retrospective observational study (LuCaBIS).

OBJECTIVES: New adjuvant treatments are being developed for patients with resected non-small cell lung cancer (NSCLC). Due to scarcity of real-world data available for treatment costs and resource utilization, health technology and cost-effectiveness assessments can be limited. We estimated the burden and cost-of-illness associated with completely resected stage IB-IIIA NSCLC in France, Germany and the United Kingdom (UK). MATERIALS AND METHODS: Eligible patients were aged ≥18 years with completely resected stage IB-IIIA NSCLC between August 2009 and July 2012. Patients (living or deceased) were enrolled at clinical sites by a systematic sampling method. Data were obtained from medical records and patient surveys. Direct, indirect and patient out-of-pocket expenses were estimated by multiplying resource use by country-specific unit costs. National annual costs were estimated based on disease prevalence data available from published sources. RESULTS: 39 centers provided data from 831 patients of whom patient surveys were evaluable in 306 patients. Median follow-up was 26 months. The mean total direct costs per patient during follow-up were: €19,057 (France), €14,185 (Germany), and €8377 (UK). The largest cost drivers were associated with therapies received (€12,375 France; €3694 UK), and hospitalization/emergency costs (€7706 Germany). Monthly direct costs per patient were the highest during the distant metastasis/terminal illness phase in France (€15,562) and Germany (€6047) and during the adjuvant treatment period in the UK (€2790). Estimated mean total indirect costs per patient were: €696 (France), €2476 (Germany), and €1414 (UK). Estimates for the annual national direct cost were €478.4 million (France), €574.6 million (Germany) and €325.8 million (UK). CONCLUSION: To our knowledge, this is the first comprehensive study describing the burden of illness for patients with completely resected stage IB-IIIA NSCLC. The economic burden was substantial in all three countries. Treatment of NSCLC is associated with large annual national costs, mainly incurred during disease progression.

Diffusion-weighted Imaging Is a Sensitive and Specific Magnetic Resonance Sequence in the Diagnosis of Ankylosing Spondylitis.

OBJECTIVE: We tested the discriminatory capacity of diffusion-weighted magnetic resonance imaging (DWI) and its potential as an objective measure of treatment response to tumor necrosis factor inhibition in ankylosing spondylitis (AS). METHODS: Three cohorts were studied prospectively: (1) 18 AS patients with Bath Ankylosing Spondylitis Disease Activity Index > 4, and erythrocyte sedimentation rate > 25 and/or C-reactive protein > 10 meeting the modified New York criteria for AS; (2) 20 cases of nonradiographic axial spondyloarthritis (nr-axSpA) as defined by the Assessment of Spondyloarthritis international Society (ASAS) criteria; and (3) 20 non-AS patients with chronic low back pain, aged between 18 and 45 years, who did not meet the imaging arm of the ASAS criteria for axSpA. Group 1 patients were studied prior to and following adalimumab treatment. Patients were assessed by DWI and conventional magnetic resonance imaging (MRI), and standard nonimaging measures. RESULTS: At baseline, in contrast to standard nonimaging measures, DWI apparent diffusion coefficient (ADC) values showed good discriminatory performance [area under the curve (AUC) > 80% for Group 1 or 2 compared with Group 3]. DWI ADC values were significantly lower posttreatment (0.45 ± 0.433 before, 0.154 ± 0.23 after, p = 0.0017), but had modest discriminating capacity comparing pre- and posttreatment measures (AUC = 68%). This performance was similar to the manual Spondyloarthritis Research Consortium of Canada (SPARCC) scoring system. CONCLUSION: DWI is informative for diagnosis of AS and nr-axSpA, and has moderate utility in assessment of disease activity or treatment response, with performance similar to that of the SPARCC MRI score.
