Introduction: Malignant pancreatic neoplasms in children and adolescents are extremely rare and potentially lethal, particularly when not diagnosed and managed early. These tumors exhibit significant histological and pathophysiological heterogeneity. Studies indicate an association between prognosis, disease stage, and the possibility of surgical resection, with the latter being the primary survival factor, especially for the most common tumors in the 0–19 age group—solid pseudopapillary tumors and pancreatoblastomas. In Brazil, there is a scarcity of updated population-based epidemiological studies on pancreatic cancer, with almost none focusing on children and adolescents, despite mortality being influenced by regional and gender disparities in the country. Objectives: To analyze and describe the epidemiological profile of pediatric and adolescent patients with malignant pancreatic neoplasms in Brazil between 2015 and 2024. Methods: This is an exploratory, epidemiological, descriptive, cross-sectional, quantitative, and retrospective document-based study using data extracted from the Hospital Information System (SIH) available in the Unified Health System’s Informatics Department (DATASUS). Hospital admissions for malignant pancreatic neoplasms nationwide from 2015 to 2024 were evaluated. Patients aged 0–19 years were analyzed, considering variables such as year, number of cases, and geographic region. Results: A total of 859 cases of pancreatic cancer were recorded in this population from 2015 to 2024. The average annual growth rate was 6.7%, increasing from 66 to 119 cases, with notable temporal variations such as in 2021 (+27.6%) and 2017 (+24%). The Southeast region had the highest prevalence, with 311 cases (32.6%), followed by the Northeast region with 269 cases (31.3%), revealing marked regional disparities. Regarding age distribution, 373 cases (43.4%) occurred in individuals aged 15–19, while 251 (29.2%) were in the 10–14 age group, indicating heterogeneous distribution across pediatric and adolescent populations. The findings demonstrate that although pancreatic cancer is rare in children and adolescents, its occurrence in Brazil showed significant growth during the years, particularly in late adolescence (15–19 years). The Southeast and Northeast regions accounted for most cases, suggesting regional disparities potentially linked to sociodemographic factors, differential access to specialized services, and diagnostic capacity. Conclusion: The increasing incidence, albeit low in absolute magnitude, underscores the need for public policies focused on early detection, strengthening pediatric oncology care networks, and expanding epidemiological surveillance systems for this specific age group.
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.
