Introduction: Malignant renal neoplasms are conditions in which kidney cells grow uncontrollably and are harmful to human health. The main type of primary kidney tumor is Clear Cell Renal Carcinoma (ccRCC), accounting for 70 to 80% of cases in Brazil, followed by Papillary Carcinomas, responsible for 10 to 15%; finally, the other types represent 5 to 10% of occurrences. The treatment of these cancers is usually done through total or partial nephrectomies, depending on the size of the tumor and its stage of progression. Objectives: This study aims to perform a comparative analysis of hospitalizations and mortality rates for total and partial nephrectomies in oncology in Brazil, with a time frame from 2019 to 2024. Methods: This is a descriptive, cross-sectional and quantitative study based on secondary data from the SUS Hospital Information System (SIH-SUS) available in DATASUS, seeking variables for indicators of hospitalizations and mortality rates of the procedures. The distribution of nephrectomies by region, the year in which they were processed, the average length of hospitalization, and the deaths caused were taken into account. Results: Between 2019 and 2024, Brazil presented 14,479 hospitalizations for total nephrectomy surgeries and 8,219 for partial nephrectomy, both in oncology. The Southeast region had the highest concentration of both operations in question, with 7,516 total nephrectomies performed and 4,624 partial ones, representing approximately 51% and 56% of the national total, respectively. On the other hand, the Central-West region had the lowest numbers of complete kidney removals, with only 767 procedures (5% of the total), while the North performed the least partial ones, with 303 surgeries (3% of the total). In addition, there was an increase in the performance of both procedures, going from 2,214 for total and 1,247 for partial in 2019, to 3,035 total and 1,762 partials in 2024, representing approximately 37% and 41% increase in hospitalizations. The mortality rate for both surgeries decreased during these years, starting at 2.64% for total surgeries and 1.12% for partial surgeries, and ending at 2.54% and 0.96%, respectively. In addition, a decrease in the average length of stay of patients in hospital was also observed, going from 6.0 to 4.8 days for total surgeries, and from 4.9 to 4.3 days for partial surgeries. Conclusion: The study demonstrated that most nephrectomies performed in Brazil are total, possibly evidencing failures in the early diagnosis of these tumors, since there was greater renal impairment. However, the notable reduction in the direct mortality rate for surgery and in the average length of hospitalizations may represent an improvement in surgical practice, since survival after the procedure was shown to be greater and recovery more effective, accelerating the discharge of patients. Thus, new studies are needed in the area to confirm these findings and, therefore, plan the best actions for national health.
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.
