  • Abstract
  • Introduction: Malignant breast neoplasms have a high incidence and are important causes of morbidity and mortality in the female population. Thus, in order to ensure early screening and treatment, in 2014, the Ministry of Health established, through the Unified Health System, the guarantee of free mammography examinations for Brazilian women in all age groups, with the age group from 50 to 69 years being the priority, following the WHO recommendation. Therefore, it is essential to analyze the effective impact of early screening of this disease. Objective: To analyze the temporal trend and projections of mortality due to malignant breast neoplasm in Brazil between 2010 and 2021. Methods: This is a cross-sectional, observational and retrospective study, which used secondary data from the Department of Information Technology of the Unified Health System (DATASUS on mortality due to Malignant Breast Neoplasm and Outpatient Production of mammography exams). The number of deaths was used to calculate the mortality rate. The collected data were separated into tables in Excel®. For modeling and forecasting, the ARIMA (AutoRegressive Integrated Moving Average) model was used, which is suitable for non-stationary time series. Results: In the period from 2010 to 2021, 190,344 deaths were recorded in Brazil. The year with the highest number was 2021, with 18,361 (9.64%) deaths, and the year with the lowest number was 2010, with 12,853 (6.75%). Regarding education, the largest number of deaths were associated with those who lacked formal education or had incomplete elementary school (1 to 7 years), with 75,302 (39.56%) and the youngest were found with no education - 15,265 (8%) - and had completed high school or higher education (12 years or more) - 24,072 (12.64%). The temporal analysis demonstrated an increasing trend until 2019, when it began to decline until the end of 2020, once again demonstrating an upward trend. The forecast (figure 1) performed by the ARIMA test demonstrated monthly values ??and trends below or following the pattern recorded over the years presented in the real rate time series (figure 2).  Conclusion: The introduction of mammography in the SUS aimed to reduce mortality from breast cancer by performing early diagnosis. However, there was a notable increase in mortality or its stabilization over the years, which can be explained by greater effectiveness in diagnosing breast cancer with the use of the exam, reducing underreporting of the disease. Furthermore, an inverse relationship was observed between education level and the number of deaths from breast cancer, reflecting the notable impact of the socioeconomic conditions of patients and the prognosis of the disease.

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.
