Introduction: Microsurgery for intracranial tumors aims primarily to allow histopathological diagnosis and surgical treatment of neoplasms located in sensitive neurological areas, using a surgical microscope to ensure adequate illumination and magnification. This approach enables precise excision of tumor lesions while preserving or restoring the patient’s neurological function. Objectives: To analyze the epidemiological profile of hospitalizations resulting from microsurgeries for the treatment of intracranial tumors in Brazil between 2013 and 2022. Methods: This is a retrospective, descriptive, and analytical study with a quantitative approach, based on data from DATASUS (SIH/SUS and Hospital Production databases). Hospitalizations for microsurgery of intracranial tumors (code 0403030145) performed from January 2013 to December 2022 were included. The analyzed variables were: annual number of hospitalizations by region, average length of hospital stay (in days), and total cost of procedures (in BRL). Statistical analysis was performed using Microsoft Excel® 365 and R® (v4.2.2) with raw data. Absolute and relative frequencies, means, and temporal variations were calculated. The hospitalization rate per 100,000 inhabitants was estimated based on IBGE population data. Results: Between 2013 and 2022, 21,336 hospitalizations for intracranial tumor microsurgeries were recorded in Brazil. The annual number of procedures ranged from 1,610 (2020) to 2,345 (2015), with a sharp drop in 2020 (?24.1%) and recovery in 2021 (+28.6%). The national average hospitalization rate was 1.01 per 100,000 inhabitants. Regional distribution was: Southeast (8,751 – 41.03%), Northeast (5,785 – 27.11%), South (3,042 – 14.26%), North (2,010 – 9.42%), and Central-West (1,748 – 8.19%). The highest average hospital stay was in the North (17.9 days) and the lowest in the Southeast (13.8 days), with a national peak in 2013 (16.3 days). The total cost of procedures was BRL 122,379,265.02, with the Southeast accounting for 42.60%, followed by the Northeast (25.38%), South (17.73%), North (8.47%), and Central-West (5.80%). Conclusion: The findings reveal significant variations in procedure frequency over the years and among regions. The Southeast and Northeast led in procedure volume and financial investment. The Southeast had the shortest average hospital stay, suggesting more efficient hospital management, while the North had the longest, indicating potential challenges in infrastructure and logistics. These results highlight disparities in resource allocation and access to neurosurgical care in Brazil, reinforcing the need for public policies that promote greater regional equity.
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.
