Introduction: Lung cancer is one of the most prevalent malignant neoplasms in Brazil, with high mortality rates, especially in advanced stages. It is classified into two main subtypes: small cell carcinoma (SCLC) and non-small cell carcinoma (NSCLC). Risk factors include smoking, occupational exposure to carcinogenic agents, and genetic predisposition. The high lethality and incidence of the disease reinforce the relevance of studies that analyze its epidemiological profile in the national territory. Objectives: To analyze the epidemiological profile of bronchial and lung cancer (ICD-10: C34) in adults living in different regions of Brazil, considering the distribution by region, year of diagnosis, sex and age group over the last decade. Methods: This is a descriptive study with a quantitative approach, based on secondary data extracted from the DATASUS Oncology Panel and the National Cancer Institute (INCA). Records of cases of malignant neoplasm of the bronchi and lungs that occurred in Brazil between 2015 and 2024 were analyzed. The variables included region, year of diagnosis, sex, age group and therapeutic modality. The data were tabulated in Microsoft Excel and analyzed descriptively, with presentation in absolute and relative frequencies. The data used were raw, without standardization, and no controls for confounding factors were applied. Results: The assessment by year of diagnosis of malignant neoplasm of the bronchi and lungs revealed a higher frequency of cases in 2023 (42.92%), with a predominance in the Southeast region (12.25%). In the stratification by sex, a higher incidence was observed in males (23.22%), followed by females (19.71%). The distribution by age group showed a predominance in the 65 to 69 age group (23.63%). Among men, this same age group presented a higher concentration (22.49%), while among women, the peak incidence occurred between 60 and 64 years (21.08%). Regarding the therapeutic modalities, chemotherapy was the most applied in women (42.10%), while the combination of chemotherapy, radiotherapy and surgery was more frequent among men (51.20%). Conclusion: This study aimed to highlight the profile of malignant neoplasms of the bronchi and lungs in adults in Brazil. The results show a higher incidence in the Southeast region, especially among men aged 65 to 69. These findings reinforce the importance of public policies aimed at prevention, such as combating smoking, and expanding access to early diagnosis, especially in regions with lower healthcare coverage. The analysis also highlights the need for specific strategies to reduce mortality associated with this neoplasm.
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.
