Introduction: Gastric cancer is a major public health concern in Brazil, ranking as the third most common cancer among men and the fifth among women in the Northern Region (INCA, 2023). Studies indicate that dietary patterns high in ultra-processed foods, especially those from fast food chains, are linked to an increased risk of gastric cancer (Wu et al., 2023). In Pará, a worrying rise in gastric cancer incidence has been observed, potentially related to shifts in eating habits, particularly greater fast food consumption. These foods, rich in fats, sodium, and preservatives, are classified as potential carcinogens by the World Health Organization (WHO, 2020). This study analyzes gastric cancer incidence in Pará between 2021 and 2024, seeking to identify possible correlations with the expansion of fast food consumption, based on data from INCA, DataSUS, and WHO. Objectives: To present the incidence of gastric cancer in Pará from 2021 to 2024 and assess the relationship between the increase in fast food establishments and cancer occurrence, aiming to inform intervention projects within the Unified Health System (SUS). Methods: This cross-sectional study used secondary, publicly available data from DataSUS (SIM) and the National Cancer Institute (INCA) on gastric cancer cases (ICD-10: C16) in Pará from 2021 to 2024. Data on fast food chain growth were sourced from the Pará Economic Development Agency (ADEPARA) and the National Health Surveillance Agency (ANVISA). Raw, non-normalized data were employed, which limits the analysis. Descriptive statistics and Pearson correlation analyses were conducted using IBM SPSS Statistics, version 26, with significance set at 5% (p < 0.05). Ethical approval was not required due to the use of aggregated public data, in line with Resolution No. 510/2016 of the Brazilian National Health Council. Results: From 2021 to 2023, gastric cancer diagnoses increased by 19.1% in Pará (INCA, 2023). Simultaneously, fast food chains grew by 35% (ADEPARA, 2024), suggesting a potential association. Statistical analysis revealed a moderate positive correlation (r = 0.62; p < 0.05) between the number of fast food establishments andgastric cancer incidence. Furthermore, epidemiological data show that 68% of diagnosed patients reported consuming fast food two or more times weekly (VIGITEL/DataSUS, 2023), supporting the hypothesis of a link between poor diet and cancer risk. Conclusion: This study aimed to explore the relationship between the growth of the fast food sector and rising gastric cancer incidence in Pará. Findings indicate a possible association; however, causality cannot be confirmed due to the cross-sectional design and use of raw data. Future research should focus on longitudinal cohort studies and systematic literature reviews to verify if these trends align with other regional or global patterns. Such investigations are crucial to support effective public health policies for cancer prevention and the promotion of healthy eating habits.
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.
