Introduction: Malignant stomach neoplasm is a relevant topic for public health due to its high global mortality rate. Gastric adenocarcinoma is the most common histological type, usually caused by infection with the bacterium Helicobacter pylori. Objective: To analyze the epidemiological patterns of hospitalizations for malignant stomach neoplasms in Brazil over a decade, with the aim of contributing to the formulation of public policies that reduce the incidence of the disease. Method: This is a descriptive, retrospective and quantitative study, based on secondary data extracted from the Department of Informatics of the Unified Health System (DATASUS). Information available in the Hospital Information System (SIH/SUS) between January 2015 and December 2024 was extracted. The following variables were analyzed: number of hospitalizations, average hospital stay, total amount spent on hospitalizations, mortality rate, gender, and age group. Results: During the period studied, 306,371 hospitalizations for malignant stomach neoplasms were recorded in the national territory. The total number of hospitalizations continued to increase between 2015 and 2019, reducing in 2020, registering a new growth from 2021 onwards. The Southeast region concentrated the highest number of hospital admissions 129,163 (42.2%), while the North region recorded the lowest 14,503 (4.7%). The total expenses related to hospital services for stomach cancer totaled R$741,722,942.89. The Southeast region led again with a total cost of R$310,682,880.71 (41.9%). The resources invested by the North region were R$34,942,157.70 (4.7%) of the amount spent throughout Brazil. The North region had the highest average hospital stay, with 9.4 days, which is equivalent to 49.2%, above the national average (6.3 days). The total mortality rate was 14.87%, which was similar between the sexes, 14.89% and 14.90%, respectively. The age group with the highest mortality was 80 years or older, representing 25.49%. Conclusion: The analysis reveals worrying information about the panorama of hospitalizations for malignant stomach neoplasm in the country, between 2015 and 2024, mainly due to the implications for public health. The approximate reduction of 9.5% in hospitalizations between 2019 and 2020 indicates possible relationships with the pandemic. The predominance of hospitalizations and expenditures in the Southeast region, the high average hospital stay in the North region, and the high mortality rate among the elderly, underline the need for public health policies aimed at prevention, diagnosis, and early treatment, as well as strategies to reduce regional and demographic inequalities in the fight against gastric cancer.
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.
