RESUMO
Introduction: Breast cancer (BC) is one of the leading causes of cancer and is the first cause of death from malignant tumors among women worldwide. New cancer therapies receive regulatory approval yearly and to avoid health disparities in society, the health systems are challenged to adapt their infrastructure, methodologies, and reimbursement policies to allow broad access to these treatments. In addition, listening to patients' voices about their therapy preferences is essential. We aim to investigate the administration route preferences [subcutaneous (SC) or intravenous (IV)] among patients diagnosed with HER2 positive BC and healthcare professionals (HCPs) and to investigate healthcare resources utilization (quality and quantity) for each route of administration (SC or IV) for treating those patients. Methods: We conducted a systematic literature review focused on clinical trials and observational and economic studies, using PubMed (MEDLINE), Cochrane Library, Virtual Health Library (VHL), Scientific Electronic Library Online (SciELO), and Latin American and Caribbean Health Sciences Literature (LILACS) databases based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Results: The literature review included 25 studies in the analysis. Studies have reported that patients and HCPs prefer the SC route of administration to IV because it saves time in terms of chair time, administration, and preparation and is less painful. In addition, SC administration might be a more cost-saving option when analyzing direct and indirect costs. Discussion: As BC stands as a significant global health concern and the leading cause of cancer-related deaths in women worldwide, understanding and incorporating patient and HCPs preferences in the choice of administration route become paramount. The observed preference for SC administration not only aligns with the imperative of adapting health systems to facilitate broad access to new cancer therapies but also underscores the importance of considering patient experiences and economic implications in shaping treatment strategies. These insights are crucial for healthcare policymakers, clinicians, and stakeholders in optimizing healthcare resources and enhancing the overall quality of BC care.
RESUMO
Objetivo: Compreender o cenário da esclerose múltipla (EM) em relação aos aspectos epidemiológicos, diagnósticos, progressão, tratamento e comorbidades no sistema público brasileiro. Métodos: Trata-se de um estudo retrospectivo e observacional utilizando os sistemas de dados do Departamento de Informática do Sistema Único de Saúde (DataSUS). Os dados utilizados foram obtidos por meio da base de dados do Sistema Ambulatorial/Sistema de Procedimentos de Alta Complexidade (SIA/SUS). Nessa base, o vínculo de registros foi por meio do Cadastro Nacional de Saúde (CNS). Para a quantificação de dados epidemiológicos, foram coletados os dados do Código de Endereçamento Postal (CEP), sexo e data de nascimento, além das bases de geolocalização dos pacientes. Considerou-se como desfecho primário a descrição epidemiológica da população de pacientes em uso ou que usaram MMCD para o tratamento da EM. Como desfecho secundário, consideraram-se as características dos pacientes (gênero, idade, idade ao diagnóstico e comorbidades). Resultados: Foram incluídos na análise 45.011 pacientes. Identificou-se predominância de pacientes do gênero feminino (72,9%) e com idade entre 31 e 60 anos (61,23%) diagnosticados com CID G35 no primeiro registro. A taxa de incidência de pacientes com EM foi maior (2,7 pacientes/100 mil habitantes) na região Sudeste, seguida pela região Sul (2,2 pacientes/100 mil). A prevalência na região Sul teve a maior taxa (18 pacientes/100 mil), seguida pelo Sudeste (16,7 pacientes/100 mil). As betainterferonas e o acetato de glatirâmer foram os medicamentos mais utilizados no primeiro tratamento. O acetato de glatirâmer foi o mais utilizado para o segundo tratamento no período de 2011 até 2017. Em 2018, os MMCD mais utilizados como segundo tratamento foram fingolimode e natalizumabe. A partir de 2019, fingolimode, fumarato de dimetila e natalizumabe foram os medicamentos mais utilizados como segundo tratamento, permanecendo nessa ordem até 2021. Para o terceiro tratamento, o natalizumabe foi o medicamento mais utilizado até 2017. Após esse período, o fingolimode passou a ser mais usado. Desde 2019, com o acesso ao fumarato de dimetila, os medicamentos mais prescritos foram, em ordem decrescente, fingolimode, natalizumabe e fumarato de dimetila. Conclusão: Estabelecer uma análise epidemiológica dos pacientes que usam MMCD para o tratamento da EM no Brasil, além do padrão de tratamento, são dados essenciais para a promoção do tratamento da EM de forma adequada, bem como para a implementação de políticas públicas locais, regionais e nacionais.
Objective: To understand the multiple sclerosis (MS) setting in relation to epidemiological aspects, diagnoses, progression, treatment and comorbidities in the Brazilian public system. Methods: This is a retrospective, observational study using the Unified Health System's Informatics Department [Departamento de Informática do Sistema Único de Saúde] data systems (DataSUS). The data used were obtained by means of the outpatient system/high-complexity procedure system (SIA/SUS) database. In this database, the association of entries was via the National Health Registration [Cadastro Nacional de Saúde] (CNS). For epidemiological data quantification, Zip Code, sex and date of birth information was collected, as well as data from patient geolocation databases. The epidemiological description of the patient population using or having used DMTs for MS treatment was considered as the primary endpoint. Patient characteristics (gender, age, age at diagnosis and comorbidities) were considered as the secondary endpoint. Results: 45,011 patients were included in the analysis. A predominance of female patients (72.9%) aged between 31 and 60 years (61.23%) and diagnosed with ICD code G35 in the first entry was identified. The incidence rate of patients with MS was higher (2.7 patients/100 thousand inhabitants) in the Southeast region, followed by the South region (2.2 patients/100 thousand). Prevalence in the South region had the highest rate (18 patients/100 thousand), followed by the Southeast region (16.7 patients/100 thousand). Interferons beta and glatiramer acetate were the most used drugs in the first treatment. Glatiramer acetate was the most used drug for the second treatment within the period from 2011 to 2017. In 2018, the most common DMTs used as second treatment were fingolimod and natalizumab. From 2019, fingolimod, dimethyl fumarate and natalizumab were the most used drugs as second treatment, remaining in this order until 2021. For the third treatment, natalizumab was the most used drug until 2017. After this period, fingolimod became more widely used. Since 2019, with access to dimethyl fumarate, the most prescribed drugs were, in decreasing order, fingolimod, natalizumab and dimethyl fumarate. Conclusion: Establishing an epidemiological analysis of patients using DMTs for MS treatment in Brazil, in addition to standard of care, results in critical data for adequately promoting MS treatment, as well as for implementing local, regional and national public policies.
