Introduction: Malignant encephalic neoplasms are cancerous cell growth on the central nervous system (CNS) which cause significant disruption of the patient’s life because of procedural damage to the CNS. Considering this scenario, it is important for the state of Pará to be watchful of reported cases, as to prepare for earlier interventions to improve the quality of life of patients with bad prognostics, and choose which could benefit from chemotherapy, especially in pediatric cases considering the special needs of these groups of patients. Public powers should be more proactive and assertive on diagnosing early stages as to choose which patients would benefit from chemotherapy or palliative care. Objectives: To analyze the epidemiological profile of mortality and morbidity from malignant encephalic neoplasms in pediatric patients (aged 0-19 years) in the state of Pará, during the period of 2020-2025. Methods: This work is an epidemiologic study done with a quantitative bias, the data were collected from government platform DATASUS, using the hospital morbidity system based on records of internations and deaths from malignant encephalic neoplasms (ICD-10: C71) in the state of Pará from 2020-2025. The study analyzed reported cases in individuals aged 0-19 years while taking in account their city, sex and race. Results: The data analysis recorded 683 hospitalizations by malignant encephalic neoplasms among patients aged 0-19 years during the analyzed period, with 53 deaths and a mortality rate of 7,76%. The capital Belém was the most affected municipality, concentrating 618 hospitalizations and 44 deaths, with a mortality rate of 7,12%. Furthermore, the hospitalizations were predominant in males (433 cases and 34 deaths) and in patients with 5-9 years (250 cases and 17 deaths, among males and females). Moreover, a racial analysis verified that mixed race people (pardo) represented the majority of hospitalizations (561 cases and 39 deaths). Conclusion: The data analysis recorded that, between 2020-2025, Belém was the municipality with the highest hospital morbidity of pediatric patients aged 0-19 years, reinforcing its role as the primary referral center for the treatment of malignant neoplastic encephalic tumors in Pará. This concentration also suggests weaknesses in early diagnosis, reporting, and access to specialized care in other regions of the state. The data study reveals male predominance of hospital morbidity and shows that the most affected age group was 5–9 years (among males and females), which may be explained by their increased health susceptibility and indicates possible delays in diagnosis or treatment access. In addition, highest concentration of cases occurred among mixed-race individuals, suggesting disparities in healthcare access linked to broader social vulnerability. Thus, towards the huge trouble of high hospital morbidity in Belém caused by the concentration of hospitalizations and deaths, it is imperative to strengthen the structure of the health system in the interior of the state, to reduce the overload of this system in the capital.
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.
