RESUMO
Acute hepatic porphyria (AHP) is a group of rare genetic diseases of heme biosynthesis resulting in severe neurovisceral attacks and chronic complications that negatively impact patients' well-being. This study evaluated the impacts of AHP on patients' physical and emotional health from a global perspective. Adult patients from the United States, Italy, Spain, Australia, Mexico, and Brazil with AHP with >1 porphyria attack within the past 2 years or receiving intravenous hemin and/or glucose for attack prevention completed an online survey assessing demographics, health characteristics, and patient-reported outcomes. Results were analyzed collectively and by patient subgroups. Ninety-two patients with AHP across the six countries completed the survey. More than 70% of patients reported that their physical, emotional, and financial health was fair or poor. Among patients who reported pain, fatigue, and muscle weakness, 94.3%, 95.6%, and 91.4%, respectively, reported that these symptoms limited daily activities. Moderate to severe depression was present in 58.7% of patients, and moderate to severe anxiety in 48.9% of patients. Of the 47% of patients who were employed, 36.8% reported loss in productivity while at work. Among patients, 85.9% reported that they had to change or modify goals that were important to them because of AHP. Aside from differences in healthcare utilization and pain severity, scores did not significantly vary with attack rate or use of hemin or glucose prophylactic treatments. AHP substantially impacts patients' physical and emotional well-being, regardless of hemin or glucose prophylactic treatment or frequency of attacks. This multinational study demonstrates that there is substantial disease burden for patients with AHP, even among those experiencing sporadic attacks or using prophylactic treatment.
RESUMO
BACKGROUND: Esophageal cancer is a highly prevalent cancer associated with low survival, especially among those with advanced disease. Second-line (2L) treatment patterns and related clinical outcomes of patients with advanced esophageal squamous cell carcinoma (advESCC) treated in routine clinical care were examined globally and regionally. METHODS: A retrospective, noninterventional study collected physician-provided chart data of patients aged ≥20 years receiving either 2L active systemic therapy or BSC following first-line active therapy for advESCC from 11 countries in Asian and Western regions (September-October 2018). Bivariate analyses examined treatment and outcomes by region. RESULTS: AdvESCC patients (Asia = 192; West = 195) were examined, of which 58.1% (Asia n = 101; West n = 124) received active systemic therapy. While regional differences in tumor classification and staging at diagnosis were observed with less advanced tumors in Asia, no regional differences for these characteristics at 2L initiation were reported. Both taxane- and nontaxane-based therapies were used as 2L therapy among Asian and Western patients, although more western than Asian patients received immuno- or targeted therapies (17.0% vs. 3.0%; p = 0.001). Alopecia (10.7%), neutropenia (9.3%), and fatigue (9.3%) were the most-commonly reported adverse events (AEs) in both regions. Significantly higher 2L AE-related emergency room visits (Asia = 22.5% vs. West = 8.0%; p < 0.001) and hospitalizations (Asia = 25.9 ± 31.2 vs. West = 4.7 ± 7.0, p < 0.001) were observed in Asian than in Western patients. No regional differences were reported for response to 2L treatment or the percent of patients who received third-line treatment/died. CONCLUSIONS: While regional variations were observed throughout the course of a patient's advESCC journey, disease response and treatment outcomes were similar.
