RESUMO
BACKGROUND: Molecular-targeted drugs and immune checkpoint inhibitors have been developed for various malignant diseases, thereby improving clinical outcomes. However, these drugs are expensive, and few studies have assessed their actual use and costs in Japan. This study aimed to survey the use and costs of first-line chemotherapy for advanced/recurrent gastric cancer (AGC) in real-world settings. METHODS: The survey included patients with human epidermal growth factor receptor type2 (HER2)-negative AGC who initiated first-line chemotherapy from January 2022 to December 2022 at the participating 92 institutions in the Japan Clinical Oncology Group. Data on the regimens were collected using Google Forms. A regimen that costs >500 000 Japanese yen (JPY) per month was defined as expensive. RESULTS: Data on chemotherapy regimens were collected from 2173 patients at all 92 institutions between March 2023 and May 2023. We analyzed 2113 patients who underwent the chemotherapy with recommended regimens and conditionally recommended regimens according to the Japanese Gastric Cancer Treatment Guidelines sixth edition. The expensive regimens were triplet chemotherapy with fluoropyrimidine (S-1 or capecitabine or 5-fluorouracil/levofolinate), oxaliplatin, and nivolumab. Their monthly costs ranged from 767 648 to 771 046 JPY. Nivolumab-containing regimens cost more than 20 times the price of conventional chemotherapy with fluoropyrimidine and oxaliplatin. These regimens were used in 1416 (67%) of 2113 patients: in 71% of patients aged ≤74 years and in 59% of patients aged ≥75 years. CONCLUSION: The regimens with >20-fold cost of conventional chemotherapy were used as first-line chemotherapy in two-thirds of patients and more than half even in the elderly population with HER2-negative AGC. This finding is important for future health economic studies on drug cost-efficacy.

Aim: To investigate the association of discordance in patient- and physician-reported symptoms on health-related quality of life (HRQoL) in hepatocellular carcinoma (HCC). Patients & methods: Data were drawn from a point-in-time survey of physicians and patients conducted in Germany, Italy and Spain (October 2018 - January 2019). Physicians and their consulting patients independently reported baseline characteristics, symptoms, treatment history and satisfaction, and HRQoL derived using the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) questionnaire. Results: Of 486 patients analysed, tiredness (73.3%, 73.7%), pain/aches (67.7%, 66.9%) and weight/appetite loss (54.3%, 53.7%) were the most common and concordant patient and physician-reported symptom domains, respectively. The symptom domains showing the largest discordance were reflux/indigestion (14.6%, 5.1%), neurological (11.9%, 5.6%), dermatological (9.3%, 6.2%) symptoms and jaundice (4.7%, 10.3%). Reduced HRQoL was observed with increasing symptom-reporting discordance. Conclusion: Further studies should investigate how symptom-reporting discordance influences patient satisfaction and HRQoL.

BACKGROUND: Osteoarthritis (OA) is the most common form of arthritis, with the knee being the joint most frequently affected, and symptomatic knee OA affecting around one quarter of the general population. For patients who do not respond to non-pharmacologic or pharmacologic treatment, surgery is a recommended option. The objectives of this study were to compare the willingness of patients with knee OA to undergo surgery, together with reasons for delaying surgery, and factors affecting successful outcomes. METHODS: A point-in-time survey was conducted in 729 primary care physicians, rheumatologists, orthopedic surgeons, and 2,316 patients with knee OA across three geographical regions: Japan, the United States (US), and Europe (EUR: France, Spain, Italy, Germany, and the United Kingdom), in order to garner their perceptions of knee surgery. Regression models were used to identify factors that might affect patients' and physicians' perceptions of surgery, including severity of OA (mild/moderate/severe), number of affected joints, surgery status, and willingness to undergo or delay surgery. RESULTS: Baseline demographics were similar between US and EUR, although patients in Japan were more likely to be female, older, and only 7% in fulltime employment. We found that few patients with end-stage knee OA, across all regions, but particularly Japan, were willing to undergo surgery (Japan 17%, US 32%, EUR 38%), either through fear, or the lack of awareness of the risk/benefits. Moreover, surgeons are prepared to delay surgery in elderly or unwilling patients, due to their dissatisfaction with the outcome, and may defer surgery in younger patients due to the need for future revision. We also identified a disconnect between physicians, of whom over 80% consider improved functioning to be the most important outcome of surgery, and patients, who seek pain relief (Japan 60%, US 35%, EUR 14%). Since physicians across all regions considered pain reduction to be an indication of surgery success (Japan 27%, US 47%, EUR 43%), this may indicate a need for improved communication to patients on the potential benefits of surgery. CONCLUSION: Managing the expectations of patients undergoing surgery remains an important goal in the treatment of knee OA and may help guide physician choice.

INTRODUCTION: Denosumab is a humanized IgG2 monoclonal antibody that was approved for the treatment of osteoporosis in Japan in 2013. This study aimed to investigate the long-term safety and effectiveness of denosumab in Japanese patients with osteoporosis in daily clinical practice. MATERIALS AND METHODS: This 3-year, prospective, observational, post-marketing study included patients who initiated treatment with denosumab (60 mg/6 months) for osteoporosis. Data were assessed at baseline, 3, 6, 12, 24 and 36 months. Key endpoints were adverse events (AEs), adverse drug reactions (ADRs), occurrence of osteoporotic fractures, bone mineral density (BMD), and bone turnover markers. Multivariate analyses were conducted to identify predictors of hypocalcaemia and percent change in BMD. RESULTS: Overall, 3534 patients were assessed (mean 75.7 years; 89.8% women). In total, 298 patients (8.4%) developed ADRs; the most common was hypocalcaemia (3.9%). Hypocalcaemia risk was significantly increased in patients with creatinine clearance < 30 mL/min, no prior use of bisphosphonates, prior use of calcium and vitamin D preparations, baseline serum calcium < 8.5 mg/dL, and no concomitant use of calcium or vitamin D preparations. Six patients had adjudicated osteonecrosis of the jaw. Lumbar spine BMD increased significantly from baseline (mean percent change: 11.4% at 36 months). All bone turnover markers decreased significantly from baseline. Over 3 years, 3.3% of patients developed a new osteoporotic fracture. CONCLUSIONS: This study confirmed the long-term safety and effectiveness of denosumab in Japanese patients with osteoporosis in daily clinical practice. No new safety signals were identified.

BACKGROUND: Understanding disease burden is imperative for improving inflammatory bowel disease (IBD) management. This real-world survey investigated residual disease burden and treatment satisfaction among European patients with moderate-to-severe ulcerative colitis (UC) and Crohn's disease (CD). METHODS: The Adelphi Real World IBD Disease Specific Programme was a multinational, cross-sectional survey with retrospective collection of patient- and physician-reported data on disease burden and management. Between October 2020 and March 2021, participating gastroenterologists recruited their next 7 (UC) and 8 (CD) eligible patients and reported demographics and clinical characteristics. Patients completed symptom, health-related quality of life (HRQoL), and treatment satisfaction questionnaires. Data were adjusted for confounding variables and compared between patients in remission (clinical remission, endoscopic remission, or both) and not in remission. RESULTS: Overall, 1040 patients (UC, nâ =â 502; CD, nâ =â 538) were included. Although most patients were in remission (UC, 66.1%; CD, 69.5%), most still reported symptoms (UC, 63.7%; CD, 74.1%), including flatulence, fatigue/tiredness, and abdominal pain/distension. In UC, there were no significant differences in the likelihood of experiencing 7 of 23 symptoms between patients in remission and not in remission. In CD, there was no significant difference in 19 of 23 symptoms between patients in remission and not in remission. Several symptoms were significantly associated with reduced HRQoL. HRQoL was significantly better among patients in remission than not in remission. CONCLUSIONS: Patients with IBD, both in remission and not in remission, experience residual symptoms that impair HRQoL. Comprehensive endpoints, incorporating HRQoL and patients' perspectives, and improved treatments are needed to address residual disease and patients' needs.
This real-world study investigated the residual burden of inflammatory bowel disease on European patients. We found that patientsincluding those in remissionexperience significant symptomatic burden and impaired quality of life, highlighting gaps in current therapeutics and patients' unmet needs.
RESUMO
BACKGROUND: Data on the effectiveness and safety of rivaroxaban for the treatment of patients with venous thromboembolism (VTE) and active cancer are limited in the Japanese real-world setting. METHODS: In this subanalysis of the J'xactly study, which was a multicenter, prospective, observational study, we evaluated the effectiveness and safety of rivaroxaban in patients with acute VTE and active cancer (nâ¯=â¯193) versus those without active cancer (nâ¯=â¯823). RESULTS: Compared with patients without active cancer, those with active cancer demonstrated a significantly different age distribution, with fewer aged <65 and ≥75â¯years; a lower proportion of women; a lower mean body mass index; and a lower proportion of physical inactivity, injury, thrombophilia, and heart failure. There was no difference in the initial dose distribution of rivaroxaban between patients with and without active cancer. The incidences of recurrence or aggravation of symptomatic VTE and major bleeding were not significantly different [VTE: 1.44â¯% vs. 2.80â¯% per patient-year, hazard ratio (HR) 0.50, 95â¯% confidence interval (CI) 0.18-1.39, pâ¯=â¯0.172; major bleeding: 4.49â¯% vs. 2.55â¯% per patient-year, HR 1.80, 95â¯% CI 0.82-3.95, pâ¯=â¯0.137]. Approximately 10â¯% of patients with active cancer died at 6â¯months, with a significantly higher cumulative all-cause mortality rate than those without active cancer (23.29â¯% vs. 2.03â¯% per patient-year, HR 11.31, 95â¯% CI 7.30-17.53, pâ¯<â¯0.001). CONCLUSIONS: In patients with VTE and active cancer, rivaroxaban showed acceptable effectiveness, although clinically significant bleeding remains a concern.

Background: Rivaroxaban, a direct oral anticoagulant, is used as a first-line treatment to prevent venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE). However, whether 21 days is optimal for the initial treatment duration has not been investigated. MethodsâandâResults: In this subanalysis of the prospective multicenter observational J'xactly study, which included 1,039 Japanese patients with acute symptomatic/asymptomatic DVT/PE who were prescribed rivaroxaban, the VTE recurrence rate and incidence of bleeding complications were assessed in 667 patients who underwent intensive rivaroxaban treatment (15 mg, twice daily) for a short (1-8 days), intermediate (9-16), or standard (17-24) duration. The short treatment duration group showed a tendency for increased VTE recurrence/aggravation compared with the standard treatment duration group (6.10% vs. 2.60% per patient-year). The intermediate treatment duration group showed a higher incidence of bleeding events than the standard treatment duration group (9.34% vs. 2.16% per patient-year), without major differences in patient characteristics between the groups. Conclusions: In this subanalysis of the real-world observational J'xactly study of VTE treatment and prevention in Japanese patients with acute symptomatic/asymptomatic DVT/PE, the standard initial intensive rivaroxaban treatment duration (17-24 days) appeared to be safe and effective, providing important insights into the clinical outcomes of the initial rivaroxaban treatment duration in this population.
RESUMO
OBJECTIVES: We assessed the effectiveness and safety of rivaroxaban in patients with isolated distal deep vein thrombosis (IDDVT). METHODS: Symptomatic venous thromboembolism (VTE) and major bleeding were assessed. RESULTS: Of 1016 patients with acute symptomatic/asymptomatic DVT and/or pulmonary embolism treated with rivaroxaban, 288 had IDDVT and 294 had proximal DVT (pDVT). The IDDVT group had fewer patients on the higher rivaroxaban dose (30 mg/day) (42.7% vs. 66.0%) and a shorter treatment duration (135.5 vs 369.5 days) than the pDVT group. VTE recurrence occurred in 14 and 11 patients with IDDVT and pDVT, respectively (2.89% vs. 2.29% per patient-year; p = 0.534). Major bleeding was less frequent in the IDDVT group (1.55% vs. 4.53% per patient-year; p = 0.044). Comparable effectiveness and safety were observed with 15 and 30 mg/day rivaroxaban in the IDDVT group. CONCLUSIONS: Short-term, low-dose rivaroxaban seems safe and effective for IDDVT treatment.

INTRODUCTION: Patients with chronic obstructive pulmonary disease (COPD) often have poor sleep quality and report a worsening of respiratory symptoms during night-time. However, current clinical guidelines for COPD management do not specifically consider nocturnal symptoms when recommending pharmacological treatment. This study aimed to better understand the burden of nocturnal symptoms in patients with COPD, and to evaluate the importance of nocturnal symptom control compared with daytime and overall symptom control. METHODS: Data were analyzed from the Adelphi Respiratory Disease Specific Programme, a point-in-time survey of physicians and their patients, conducted in the USA in 2019. Primary care physicians and pulmonologists who managed three or more patients with COPD per month were eligible for inclusion; eligible patients were ≥ 18 years old, with a physician-confirmed diagnosis of COPD. RESULTS: Surveys from 171 physicians and 800 patients were analyzed. Everyday symptoms were reported in 14% of patients. In total, 88% of patients reported daytime symptoms, and 74% of patients experienced nocturnal symptoms, with 7% reporting daily nocturnal symptoms. Patients experiencing nocturnal symptoms every day had the greatest impairment in their activity as per the Work Productivity and Activity Impairment questionnaire (mean total activity impairment, 66.9%; nocturnal symptoms once or twice a week, 41.1%; no nocturnal symptoms, 26.4%). Patients experiencing daily nocturnal symptoms also had the lowest quality of life (QoL) as per the EuroQoL 5-Dimension 3-Level score. Physicians reported prescribing therapy based on sustained 24-h symptomatic relief for the majority of patients (78%). They reported nocturnal symptom control as a factor in their choice of therapy for 38% of patients, and daytime symptom control as a reason for 61% of patients. CONCLUSION: Daytime and nocturnal symptoms are common among patients with COPD. Frequency of nocturnal symptoms is related to a significant impairment in activity and health-related QoL.
RESUMO
PURPOSE: To understand similarities and differences in patient treatment goals as selected by US psychiatrists, adult patients with schizophrenia, and their caregivers in a real-world setting in the United States, including stratification by current medication and age. PATIENTS AND METHODS: Data were drawn from the Adelphi Schizophrenia Disease Specific Programme™, a point-in-time survey of psychiatrists and their consulting adult patients with schizophrenia, conducted from June to October 2019. Psychiatrists completed record forms for their next 8 consecutive outpatients and (where possible) 2 inpatients matching inclusion criteria. Participating psychiatrists, patients, and caregivers completed treatment goal questionnaires as part of the survey. RESULTS: Psychiatrists (n = 124) provided data on 1204 patients with schizophrenia, including 1135 on drug treatment (207 inpatients [18%] and 928 outpatients [82%]); questionnaires were completed by 555 patients and 135 caregivers. Decrease in disease symptoms was identified as the most important patient treatment goal by patients (64%), psychiatrists (selecting for 63% of patients), and caregivers (selecting for 68% of patients). Patients, psychiatrists, and caregivers similarly rated the least important goals (less sexual problems and less weight gain). Patients indicated their current medication helped to reach their most important goals: decrease in disease symptoms (68%) and thinking more clearly (39%). Findings based on analysis of treatment goals by treatment and age were similar to overall trends. CONCLUSION: These findings, including identification of a primary consensus goal of decrease in disease symptoms, may help with discussions between patients with schizophrenia, psychiatrists, and caregivers to inform effective management strategies and encourage shared decision-making.
RESUMO
Background During the coronavirus disease 2019 pandemic, three-dimensional (3D) printing was utilized to rapidly produce face shields for frontline workers in response to an acute shortage of personal protective equipment (PPE). In this study, we examine the perceived utility and performance of 3D-printed (3DP) face shields through a survey of frontline workers in Ontario, Canada. Methodology Frontline workers who received community-produced 3DP face shields from the Canadian initiative "3DPPE GTHA" (March-December 2020) were invited to participate in the study. The survey response rate was 54.3%. Of 63 respondents, 39 were patient-facing and 24 were community-facing frontline workers. Participants were asked to rate performance measures in 10 categories on a five-point Likert scale. Data were categorized by organization and frontline worker type, and a t-test was used to determine statistically significant differences among subgroups. Results The mean preference for 3DP face shields among respondents was 3.2 out of 5 (95% confidence interval [CI]: 2.1-4.3). Community-facing respondents reported significantly greater overall utility scores for 3DP face shields (3.58, 95% CI: 3.38-3.79) compared to respondents working in a patient-facing profession (2.95, 95% CI: 2.77-3.13; p < 0.05). However, no differences were reported in portability and compatibility with other PPE. Respondents from organizations with large service volumes reported significantly lower overall utility scores (2.67, 95% CI: 2.44-2.89) than respondents in organizations with smaller service volumes (3.45, 95% CI: 3.28-3.62; p < 0.05). Conclusions Community-facing frontline workers and those from smaller service volume organizations endorse higher utility for 3DP face shields than patient-facing frontline workers. Despite this, frontline workers generally rate 3DP face shields positively. 3DP face shields are a viable option for personal and community use and can be used to supplement supply in a community setting.
RESUMO
The use of hydrogen for cancer control has made great progress in cytology and animal experiments. With the increasing number of hydrogen products on the market, larger numbers of advanced cancer patients have participated in clinical trials or received treatment at home after purchase. Our study reported a real-world survey from 82 patients with good cancer control using hydrogen products, including real world evidence from patients who received ineffective traditional treatment, patients who received traditional treatment that failed, or patients who refused traditional treatment. Two typical cases were reported herein. Subsequently, we included studies on the mechanism of hydrogen oncology. The mechanism of cancer control using hydrogen includes the inhibition of tumor cells and the activation of exhausted lymphocytes. Large-scale real world evidence has shown clinical value, and yet remains to be further developed and researched.

Advanced cancer treatment is a huge challenge and new ideas and strategies are required. Hydrogen exerts antioxidant and anti-inflammatory effects that may be exploited to control cancer, the occurrence and progression of which is closely related to peroxidation and inflammation. We conducted a prospective follow-up study of 82 patients with stage III and IV cancer treated with hydrogen inhalation using the "real world evidence" method. After 3-46 months of follow-up, 12 patients died in stage IV. After 4 weeks of hydrogen inhalation, patients reported significant improvements in fatigue, insomnia, anorexia and pain. Furthermore, 41.5% of patients had improved physical status, with the best effect achieved in lung cancer patients and the poorest in patients with pancreatic and gynecologic cancers. Of the 58 cases with one or more abnormal tumor markers elevated, the markers were decreased at 13-45 days (median 23 days) after hydrogen inhalation in 36.2%. The greatest marker decrease was in achieved lung cancer and the lowest in pancreatic and hepatic malignancies. Of the 80 cases with tumors visible in imaging, the total disease control rate was 57.5%, with complete and partial remission appearing at 21-80 days (median 55 days) after hydrogen inhalation. The disease control rate was significantly higher in stage III patients than in stage IV patients (83.0% and 47.7%, respectively), with the lowest disease control rate in pancreatic cancer patients. No hematological toxicity was observed although minor adverse reactions that resolved spontaneously were seen in individual cases. In patients with advanced cancer, inhaled hydrogen can improve patients' quality-of-life and control cancer progression. Hydrogen inhalation is a simple, low-cost treatment with few adverse reactions that warrants further investigation as a strategy for clinical rehabilitation of patients with advanced cancer. The study protocol received ethical approval from the Ethics Committee of Fuda Cancer Hospital of Jinan University on December 7, 2018 (approval number: Fuda20181207).

INTRODUCTION: Rivaroxaban, a factor Xa inhibitor used as a direct oral anticoagulant, is beneficial over warfarin in terms of food-drug interactions and the need for therapeutic monitoring in patients with acute venous thromboembolism (VTE), including deep vein thrombosis and pulmonary embolism. Because there is little data regarding VTE treatment in Japan, a real-world survey of Japanese patients being treated with rivaroxaban for VTE is needed. METHODS AND ANALYSIS: The Japanese Registry of Rivaroxaban Effectiveness & Safety for the Prevention of Recurrence in Patients with Deep Vein Thrombosis and Pulmonary Embolism has been established to investigate the clinical outcomes of rivaroxaban for the initial treatment and prevention of symptomatic recurrent VTE in Japanese patients with acute symptomatic/asymptomatic VTE. 150 institutions in Japan will enrol patients in the study; the target enrolment is 1000. All patients will be followed up two times a year for at least 18 months and up to 3 years after their enrolment. The primary outcome is symptomatic recurrent VTE occurring during the study period. The principal safety outcome is clinically relevant bleeding (ie, major bleeding or clinically relevant non-major bleeding) occurring during treatment. A clinical events committee will adjudicate all outcomes. ETHICS AND DISSEMINATION: The study protocol has been approved by the Nihon University Itabashi Hospital, Clinical Research Ethics Committee and all local institutional ethics committees of the participating hospitals. Findings of the study will be presented in scientific sessions and will be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03091621,UMIN000025072; Pre-results.
