Introduction: Malignant brain neoplasms are characterized by uncontrolled cellular proliferation within the brain parenchyma or adjacent structures, exhibiting significant histopathological heterogeneity and posing substantial therapeutic challenges. Among these, gliomas - including astrocytomas, ependymomas, and oligodendrogliomas - are among the most prevalent primary malignant tumors of the central nervous system. In Brazil, despite their relatively low incidence, these neoplasms are associated with high morbidity and mortality rates, necessitating hospital admission for patient survival. Risk factors such as age and genetic predisposition further complicate the clinical landscape. Thus, regional epidemiological studies are crucial for identifying population susceptibilities and informing public health strategies. Objectives: This study aims to analyze the profile of hospitalizations due to malignant brain neoplasms in Brazil's Northern Region from 2019 to 2024, examining associated risk factors and discussing the impact of related hospital costs. Methods: An ecological, descriptive and retrospective study of hospitalizations due to malignant brain neoplasm in Brazil’s Northern Region, between 2019 and 2024, was conducted using data from the Hospital Information System of the Brazilian Unified Health System (SIH/DATASUS). Variables analyzed included sex, age, race/color, type of care, mortality rate, temporal evolution, and total hospitalization costs. Results: Between 2019 and 2024, 4,145 hospitalizations for malignant brain neoplasms were recorded in Brazil's Northern Region. The majority of patients were male (n=2,299). Regarding race/color, white individuals accounted for the highest number of hospitalizations (n=304), while indigenous individuals had the lowest frequency (n=23). The most affected age group was 50 to 59 years (n=735), followed by 60 to 69 years (n=672) and 40 to 49 years (n=506); the lowest rates were observed in children under 1 year (n=20). Emergency care was the predominant type of admission (n=2,883). An increasing trend in hospitalizations was noted over the study period, with the lowest number in 2020 (n=582) and the highest in 2023 (n=769). The associated hospital mortality rate was 16.5%, and the total cost of hospitalizations for this condition in the region amounted to R$15,154,278.61. Conclusion: Age and race were significant risk factors for hospitalizations due to malignant brain neoplasms in Brazil's Northern Region. The high hospital costs recorded during the study period, coupled with the upward trend in hospitalizations, underscore the importance of understanding the disease's epidemiological profile to inform health strategies aimed at reducing hospitalization needs.
It is with great enthusiasm that we present the Annals of the Oncology International Symposium 2025, an event that continues to solidify its significance in the oncology landscape of northern Brazil. Held in Belém, Pará, Oncology 2025 centered around the theme "The cancer control challenge: better knowing it to best facing it," dedicating itself to exploring the latest frontiers in cancer treatment and prevention.
This year, the symposium provided a deep dive into the essential role of knowledge in the fight against cancer, presenting new perspectives and scientific advancements across various areas of oncology. Renowned global experts gathered to share their most recent research and innovative approaches, offering participants a comprehensive view of the challenges faced by healthcare professionals and patients worldwide.
Presentations and discussions during the event focused on critical topics such as the use of new technologies, advancements in personalized therapies, and more effective prevention strategies. Additionally, particular attention was given to the unique challenges faced by the Amazon region, with efforts aimed at developing region-specific solutions to meet local needs.
Beyond being a high-caliber academic event, Oncology 2025 stood out as a moment for integration and professional networking, with the warm hospitality of the city of Belém offering participants a unique experience. This event became a platform for exchanging ideas, where science, culture, and humanity came together in pursuit of a common goal: to improve cancer control both in Brazil and globally.
This collection of abstracts and articles presented during the event reflects the ongoing dedication to research and the development of innovative solutions, highlighting the importance of collaboration and shared knowledge in the fight against cancer.
