Introduction: Exploratory laparotomy is a surgical procedure involving the opening of the abdominal cavity for the purposes of investigation, diagnosis, and treatment of various pathologies. In the oncological context, this practice is widely used for the partial or total resection of tumors located in abdominal organs, being a procedure potentially associated with epidemiological factors in the North Region of Brazil. Objectives: To describe the epidemiological profile of exploratory laparotomies with parcial or total tumor resection in Oncology in the North Region of Brazil, in the period of 2018 to 2024. Methods: Epidemiological study of a cross-sectional and observational nature based on secondary data. The research was conducted through consultation of the databases of the Department of Informatics of the SUS (DATASUS). The collected data were organized and analyzed according to the following variables: state of hospitalization occurrence, deaths and hospitalizations by year of processing, average duration of hospitalization in days, total annual cost of procedures and mortality rate. The data obtained were analyzed using Microsoft Office Excel 2019. Subsequently, a descriptive and comparative approach to this information was carried out. A Spearman’s correlation test was performed to assess a possible relationship between the average duration of hospitalization and mortality rate of hospitalized patients of each state of the North Region. A p-value less than 0.05 (p < 0.05) was used as the reference for statistical significance. Results: A total of 556 hospitalizations were recorded in the North Region between the years 2018 and 2024. Of these, 257 were registered in Tocantins (46.22%), making it the state with the highest number of hospitalizations, followed by Pará with 160 (28.72%). The year of 2019 had the highest absolute number of hospital admissions in the region, with 119 cases (21.40%), but not the highest number of deaths. Of the 61 total deaths in during the period, 16 (26.22%) occurred in 2020, making it the year with most fatal events. The average length of hospitalizations in the context of exploratory laparotomy was 12.6 days in the North Region, with Acre having the highest average duration (17 days) and Roraima the shortest (4.3 days). The total cost, in Brazilian reais, of the surgeries across all states during the period was R$ 3,331,803.19, with 2019 being the year of the highest expenditure (R$ 672,449.53, accounting for 20.18% of the total). Tocantins was the federative unit with the highest spending (R$ 1,488,662.80), representing 44.68% of the total amount spent by the states from 2018 to 2024. The average mortality rate during the period was 10.97%, with 2023 being the year with the highest mortality rate (16.95%) and 2024 the lowest (5.88%). There was no statistically significant monotonic correlation between the length of hospitalization and the mortality rate (p = 0.8191). Conclusion: This study highlights significant epidemiological disparities in exploratory laparotomies for oncological tumor resection in Brazil's North Region. By analyzing variables such as hospitalization rates, mortality, and costs, it provides critical insights into regional healthcare demands, supporting more effective planning and resource allocation in oncological surgery.
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.
